Since the beginning of time, man has looked for better ways to navigate. Land exploration was easier because of the various landmarks that prevailed, but oceanic exploration was an entirely different challenge. Early sailors created primitive charts of the coast lines and learned to look to the sun and stars for direction. Over time, man developed instruments such as the compass, quadrant, sextant and chronometers to assist sailors in charting their course. The first gyroscope compass that pointed true north was not invented until 1907. Radio detection and ranging (radar) was invented in 1935, and then long range navigation (Loran) was developed during World War II. But late in the 20th century, NAVSTAR, the official name for the global positioning system (GPS), was invented for military use. Between 1978 and 1994, the US Department of Defense launched 24 satellites into space. These satellites, which orbit about 12,000 miles above the earth and travel at 7,000 mph, complete two orbits every 24 hours. The satellites, each weighing about 2,000 pounds, are 17 feet wide and powered by solar panels. After about 10 years of service, a replacement satellite is launched into orbit to keep up the accuracy of the system. In the 1980s, the US government decided that the GPS system should also be available for civilian use. Today, GPS has become a necessity for all modes of transportation. When your GPS receiver is locked onto four or more satellites, it can determine latitude, longitude, altitude, speed, the time of sunrise and sunset and so much more. We are truly living in a fast-paced electronic era where a space-based global navigation system, maintained by our government with free accessibility to anyone with a GPS receiver, now provides us with the information we need for travel. And as fast as this new information age is emerging, it is a wonder to imagine what the next decade will bring.

Water is revitalized via equipment that is installed in the water distribution. Equipment is based on purely physical, hydrodynamic principles when water flows through the chambers and passageways that are specifically arranged. This principles transfer part of water molecules power. Kinetic energy of the water flow is passed to positioned energy of water molecules. We call this action water structuralization - because energy rebuilds, creates and makes bonds in the internal water structure strength. Each product line for water revitalization is different - in design, efficiency, complexity of the technology, material resistance, internal and external surface modification , etc. We recommend that you discuss your choice of water revitalization unit with your supplier or with us. There are a lot of things to consider for the best choice, e.g. for appropriate efficiency we need to know the real flows more than just the diameter of pipes. All our products can operate independently or as part of a cascade of water treatment system. Some physical characteristic of water is changed - such as the polarity of the solution, the degree of solvation (hydration) of dissolved substances - even those inserted after adjusting the water activity of dissolved ions and molecules, gas solubility, etc.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
Occurring more than 300 million years ago, dragonflies form one of the most ancient groups of insects. With more than 6 000 species world-wide, they have fascinated numerous civilisations over the ages. Their many popular names (in the Middle Ages, for example, they were known as ‘Satan’s needles’, ‘Devil’s arrows’ and ‘dragon’s whores’) illustrate the fear and demonic reputation they have held over a long period. However, in the Far East, these insects are regarded with great respect, notably in Japan – the town of Nakamara has even devoted a museum to them, unique of its type – where they represent a symbol of force and bravery, and their silhouette is regarded as synonymous with good luck and victory. Emblems of our water courses and wetland areas, dragonflies are among the most popular of insects. However, every fisherman, walker or naturalist one meets by the riverside will tell you that these insects are becoming less and less numerous. Such anecdotal evidence has motivated societies for nature conservation and the environment in the Poitou-Charentes to conduct a survey to refine our knowledge of these insects. The aim is to conserve dragonfly populations and their habitats and to bring dragonflies to the attention of the public, especially those involved in decision-making, principally by the publication of this book. The dragonfly world < Click here to see more (pdf) > The dragonflies, or Odonata, are one of the earliest groups of insects, first appearing during the age of the dinosaurs. The European species are divided into 2 major groups : the Zygoptera, or damselflies, and the Anisoptera, or true dragonflies. The 6000 species described in the world are morphologically uniform but they have developed diverse ecologies allowing them to colonise nearly the entire terrestrial surface of the planet. Biology and Ecology < Click here to see more (pdf) > Compared with many other groups of organisms, the morphology, life-cycle and general ecology of members of the Odonata are relatively homogeneous. Their most striking characteristic is that they are dependant on 2 radically different media – the aquatic one in which their larvae develop and the aerial world of the adults. This life-cycle switch is accompanied by fundamental physiological transformations (changes in methods of respiration, development of the organs of reproduction), morphological transformations (use of wings) and, conspicuously, behavioural transformations (changes in hunting methods, development of reproductive behaviour). < Click here to see more (pdf) > Although dragonflies can be found in many different habitats and throughout much of the year, certain areas and certain periods are most suitable. To know where and when to look for them, together with a knowledge of their ecology and behaviour are very valuable. In this chapter, information on flight periods, sites to visit and the equipment needed to observe and identify them is provided. Photographing dragonflies – practical advice : Damseflies (Zygoptera) tend to adopt a look-out post (a plant stem or twig by the waterside) and when disturbed, take off, only to re-alight again in exactly the same place a few moments later. Approach to within 50 cm of the damselfly and focus the camera before the insect takes off. When it departs, remain as still as possible, keeping your camera focused on its perch, and then, from the moment you have it in the view-finder you have several seconds in which to press the shutter. True dragonflies (Anisoptera) tend to fly hardly without stopping and it’s even more difficult to photograph them successfully ! You need to stand quietly in the flight area of your dragonfly and wait until it becomes used to your presence. With a little luck it will come to investigate you, hovering before you for a second or two. This is the time you have to frame it in the field of view and press the shutter – not easy ? Identifying the dragonflies of the Poitou-Charentes The identification of dragonflies begins with an ‘apprenticeship’. Start by learning to recognise the commonest species. To conduct a systematic survey of the species present in a locality one must obey one simple rule : to identify with certainty each species present on the site. To do this, capture is essential. In this chapter, identification keys for each of the families are provided. Identification should be based on several characters and on mature individuals. Sure identification of immature or worn examples is more difficult. Binoculars are useful for observing dragonflies, particularly Anisoptera, in the field. The use of photography, with the aim of recording salient features, is useful in constructing a personal reference collection and in confirming identifications. The identification of the exuviae, the skin of the larva from which the adult has emerged, also provides valuable information on the dynamics of a population. Although much less spectacular than the adults, the forms of the exuviae are very diverse. Never to name a species where a doubt remains must remain the rule as much for the larvae and exuviae as for the adults. The dragonflies in their habitats From the results obtained during our surveys, we have tried to identify the range of dragonflies typical of each of the principal habitat types to be found in the Poitou-Charentes. For each of these habitats, only the species for which we have proof of reproduction have been included. Threats linked to human activities Nearly 40% of the species of dragonflies of the Poitou-Charentes are included in the regional list of threatened species. Most suffer from the impact of human activities on humid zones, which constitute an ecosystem particularly fragile and vulnerable. The profound changes to which these areas are submitted, outweigh the adaptive capabilities of many specialised species. Although dragonflies are considered as poor bio-indicators because they are quite tolerant of environmental change, the decline of their populations indicates the overall sad state of our wildlife heritage. Of the 68 species of Odonata present in the Poitou-Charentes, 10 are protected at the European and national level. However, an evaluation of the conservation status of our species indicates that 29 are gravely threatened on a national and regional scale. The conservation of dragonflies is provided by comprehensive measures for the protection of humid zones and a better consideration of the requirements of species in the management of natural habitats. The construction of ornamental ponds in gardens could begin to play an important role in the protection of certain species.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
Did you know that there are currently roughly 62 million adults ages 65 and older living in the US? This number is projected to nearly double by 2050. As we continue to live longer lives, it’s important to focus on maintaining our physical and mental well-being. One powerful tool for doing so is using mindfulness activities for seniors. This practice involves being fully present and aware in the moment, without judgment. In this section, we’ll explore the benefits and techniques to promote well-being and relaxation. Read on to discover how mindfulness can enhance your golden years. As we age, our bodies and minds go through various changes. Chronic pain, memory loss, stress, and anxiety are just a few common challenges that seniors may face. Fortunately, research has shown that mindfulness can help alleviate these issues and improve overall well-being. Here are some specific benefits of mindfulness for seniors: Improved Cognitive Function As we get older, our cognitive abilities may start to decline. However, studies have found that practicing mindfulness can improve cognitive function. It can slow down age-related declines in memory and attention. This is because mindfulness helps us focus on the present moment and reduce distractions. Reduced Stress and Anxiety Stress and anxiety are common issues that many seniors face. Mindfulness can help alleviate these feelings by promoting relaxation and reducing negative thoughts. Practicing mindfulness has been linked to reduced levels of cortisol. This is the hormone responsible for stress and anxiety in our body. Better Physical Health Mindfulness has also been shown to have a positive impact on physical health. It can help lower blood pressure, reduce inflammation, and improve immune function. These benefits can help seniors maintain their health and prevent chronic diseases. Techniques for Mindfulness Now that you’ve learned about the benefits of mindfulness, here are some techniques and activities for the elderly: One of the simplest ways to practice mindfulness is through breathing exercises. Find a comfortable seated position and focus on your breath. Inhale deeply through your nose, hold for a few seconds, then exhale slowly through your mouth. Repeat this for a few minutes. Body Scan Meditation This technique involves bringing awareness to different parts of your body. Starting from your toes and moving up to the top of your head. Pay attention to any sensations or tension you may feel in each area, without judging them. This can help you feel more relaxed and connected to your body. You don’t have to sit still to practice mindfulness. Take a slow, deliberate walk and focus on the sensations in your feet as they touch the ground. Observe your surroundings without judgment and pay attention to the present moment. To help you with these techniques, check out the leading assisted living community in Palm Beach Gardens. They offer various wellness programs and engaging senior activities, including mindfulness classes. Mindfulness Activities for Seniors: Promoting Health and Wellness Mindfulness is a powerful tool that can benefit seniors in their golden years. It can improve cognitive function, reduce stress and anxiety, and promote physical health. By incorporating mindfulness activities for seniors into our daily routines, we can enhance our quality of life and continue to thrive as we age. So take some time today to practice mindfulness and reap its many benefits. Your future self will thank you.

On the afternoon on December 10, 2018, an area of what initially appeared to be precipitation (Figure 1) was detected northwest of Evansville, Indiana by the National Weather Service (NWS) Doppler Weather Radar station at Paducah, Kentucky (KPAH). When first detected, the blob was 100 nm northeast of KPAH at an elevation of approximately 12,000 feet. A check of surface weather stations near the blob and visible satellite imagery (Figure 2) indicated that no precipitation was occurring and that skies were clear in the area. The blob was visible by the KPAH radar for nearly ten hours (from 2:49 pm on December 10 to 12:49 am on December 11, 2018 CDT). During this time, it traveled approximately 120 nautical miles (average of 12 knots) in a southeasterly direction from southeastern Illinois to western Kentucky (see animation below). If it wasn’t precipitation, what was the radar station detecting? It’s not uncommon for migrating birds to appear on radar, but at a height of 7,000 to 10,000 feet, the blob was too high to be birds. Dust and insect swarms sometimes appear on radar, but the elevation was too high for these also. Not to mention it is the wrong time of year for insect swarms. While impossible to confirm, the evidence suggests the blob was chaff from a military aircraft. Traditional military aircraft lack radar-avoiding technology and must rely upon defensive countermeasures. Primary among these is chaff, a fibrous substance composed of glass fibers and aluminum packed into small bundles. The pilot launches the bundle into the aircraft’s slipstream, where it opens and releases nearly five million small fibers (1 to 2cm in length) into the atmosphere forming a highly-reflective masking “cloud.” The dispersal of the chaff is intended to confuse a missile’s radar guidance system by creating a more attractive target than the plane that released it. Since the rapid dispersal of the chaff cloud would be counter-productive, the material is designed to linger in the atmosphere for an extended period. Falling at a rate of approximately ten meters per minute, chaff dispersed at an altitude of ten thousand feet doesn’t reach the ground for nearly ten hours. The fibers are also highly resistant to breaking apart during descent helping to prolong their protective mission. The Evidence For Chaff A zoomed-in reflectivity image (Figure 3) at 2:49 pm CDT on December 01, 2018 shows the blob shortly after it initially appeared on radar. The high values of dBZ (55 dBZ) associated with the blob are consistent with chaff when the radar station is in clear air mode. (Clear air mode is slower than the standard precipitation mode and increases the station’s ability to detect small particles such as dust and mist.) Correlation coefficient (CC) is a radar product that measures the uniformity of the target’s shape. Targets will high CC values (close to 100%) are round, such as perfectly formed raindrops or snowflakes. The correlation coefficient image at 2:49 pm CDT on December 10, 2018 (Figure 4) shows the blob had values less than 60% which typically suggests chaff or other non-weather related targets. Based on data associated with the KPAH radar beam, the presumed cloud of chaff extended from an altitude of approximately 7,000 to 10,000 feet. This height roughly correlates to 700 mb, one of the standard atmospheric levels analyzed by meteorologists. The impact of friction is virtually absent at 700 mb, therefore the wind flows nearly parallel to the contours of constant height (the dark lines on Figure 5). A review of the 700 mb analysis valid at 7:00 pm on December 10, 2018 (Figure 5) indicates the wind above southeastern Illinois and western Kentucky was likely northwesterly to northerly at approximately 15 to 20 knots. The observed sounding at Nashville, TN at 7:00 pm on December 10, 2018 (Figure 6) confirms that wind speeds at the height of the presumed chaff cloud were rather light at approximately 15 knots. The absence of precipitation, the longevity of the cloud’s appearance on radar, and its movement consistent with the speed and direction of the wind at 700 mb, supports the conclusion that the cloud was military chaff.

As we stated at the very beginning, for most students and teachers this area of study touches on the very private and unique part of a person. But if the teacher is committed and truly believes in the positiveness of what he/she is doing it will be a beneficial endeavor. Another problem the teacher will have to face is the lack of homogeneity even in a bilingual class. Some students might be almost unable to speak English and have very Hispanic values while others will be well on their way to being americanized and might consider themselves more “modern” (“with it”) than their more conservative peers. The teacher will have to act as mediator in the possible conflicts that may arise out of these differences. Finally, the teacher must be aware that he/she will most probably need a peer support system for him/herself. In times of self-doubt, such as direct attacks on sex educators in the media or a student relating an explosive sexual experience such as incest, support from a respected peer can be invaluable. All things considered, we feel that an examination of Family Life and Human Sexuality is essential to normal growth and development.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
here you will find all the answers to the most frequently asked questions about tartar formation. Dr. Gambino, dental hygienist, gives advice for dental hygiene at home. If there are still unanswered questions, send us a message via email or on Instagram. WHAT IS TARTAR AND HOW DOES IT FORM? Tartar is nothing more than mineralized bacterial plaque (multi-species microorganisms organized to colonize the surfaces of the teeth). The amount of tartar that forms varies depending on several factors, such as age (the older you get, the more tartar you have), gender (males are more predisposed), race, dental location, and, of course, poor oral hygiene. Tartar formation occurs following the deposition on the dental surface of organic and inorganic bacterial matrix (such as the mineral salts present in saliva), which if not removed daily tend to harden and can only be eliminated with a professional hygiene session. HOW CAN I RECOGNIZE TARTAR? Generally, we can find it on the lower incisors and upper molars. It has a yellow color that turns orange depending on how "old" it is (in smokers it tends to brown/black). There are plaque detectors and tartar on the market that, in the form of liquids or candies, color the bacteria so that the patient can clearly see the amount and location. Once colored, just take the toothbrush and properly brush your teeth, you will see that the color from the surface of the teeth will pass directly onto the bristles. Receive plaque detectors for free by purchasing a promis kit WHAT ARE THE CAUSES/BENEFITS OF TARTAR? Tartar formations have no benefits for our oral health, on the contrary, they constitute the ideal environment for bacterial development. In fact, thanks to its organic component, it can adhere to all surfaces of the oral cavity (teeth, implants, crowns, bridges, fillings, prostheses) and due to its porosity, it creates niches where bacteria proliferate undisturbed, secreting inflammatory substances harmful to the health of oral tissues. WHY AND HOW OFTEN SHOULD IT BE REMOVED? Removing tartar is the basis of preventing bacteria-dependent pathologies that we can find in the oral cavity. Being a structure capable of hosting microorganisms, the less there is, the less they can organize and cause us problems (cavities, abscesses, gingivitis, periodontitis, etc). Generally, professional oral hygiene should be done every 6 months. This timing can vary depending on several factors (patient's manual dexterity, genetic predisposition, motor disabilities, presence of prostheses, etc.) and can range from a minimum of 45 days to a maximum of 12 months. The professional will evaluate, from time to time, the most appropriate timing for the next recall. HOW DOES IT USUALLY WORK? On average, an oral hygiene session lasts from 45-60 minutes. There are steps to follow to ensure a truly professional and useful job for the patient's health. After the compilation and study of the medical history form an accurate inspection of the oral cavity must be performed to evaluate any past or ongoing problems (and if necessary, refer to the most suitable dentist for a diagnostic visit) and understand the patient's hygiene gaps to instruct and correct them as best as possible. Once the patient has understood any corrections to be made, we must go physically to remove plaque, tartar and extrinsic stains from the surfaces of the teeth or prostheses using manual or mechanical instruments that with their movements can clean, polish, and disinfect oral structures. The hygiene session is never painful! It can be slightly annoying when there are abundant plaque accumulations caused by hygiene appointments too far apart or poor home hygiene manual dexterity of the patient. In this case, we can still take advantage of using specific mouthwashes, local anesthetics, or nitrous oxide... ZERO FEAR OF THE DENTIST! WHAT HAPPENS IF TARTAR IS NOT REMOVED? When we do not have professional hygiene for a long time or do not remove plaque daily with a toothbrush, there is an increase in the number and change in the "quality" of bacteria present in the mouth. These are detected by our immune system and the defense mechanism of inflammation is activated, which, if not promptly treated, can lead to gingivitis and if it persists over time becomes periodontitis. HOW CAN TARTAR BE PREVENTED? The only way to prevent tartar formation is proper oral hygiene by removing bacterial plaque daily. Cleaning the oral surfaces should occur about 15 minutes after the end of each meal (to give time for saliva to restore the correct pH of the mouth). After applying a small amount of toothpaste to the bristles of our toothbrush (about the size of a grain of rice) and with light pressure, perform rolling movements from the gum towards the center of the mouth for about 2-3 minutes to touch all the surfaces of the tooth (both vestibular and oral). It is very important to use dental floss to remove food residues and plaque deposited between the teeth, to be used always but with particular dedication in the evening before going to bed. However, it must be said that, despite our skill and dedication, we may always find small accumulations of tartar located, for example, in crowded teeth or very posterior teeth (such as wisdom teeth). We must not be discouraged, but simply pay more attention to small spaces! A TIP FOR THE RIGHT TOOTHBRUSH? Manual or electric toothbrush? Soft, medium, or hard bristles? There is no perfect toothbrush, there is the most suitable toothbrush for us. During a professional hygiene session, after evaluating the patient's manual dexterity and the type of dental anatomy, a more precise answer to these questions can be given. Normally, I recommend using toothbrushes with soft bristles and very dense, without rubber inserts and with anatomical handles for a firm and precise grip. The friction of the bristles on the tooth determines the removal of plaque, which is why toothbrushes with many bristles are the best. However, it is very important not to exert excessive force that would cause premature enamel wear and gingival recession. Generally, if the same toothbrush is used daily, it should be replaced every maximum of 3 months; for this reason, I recommend eco-friendly toothbrushes. Finding one that encompassed all the characteristics I wanted was not easy, they always had something that was not right, until I tried the Promis line and I am not just talking about toothbrushes but also toothpastes and periodontal gels. The head of a promis toothbrush is very small (about 1cm) and allows you to touch the entire tooth, even the most hidden surfaces! It contains 6750 soft, dense, and thick bristles, properly fixed to a handle made of bioplastic shaped to have an anatomical grip that fits the person's hand. The toothpastes and periodontal gels are naturally based and contain 6 different herbs (Eucalyptus, rosemary, bergamot, tea tree, mint, and neem) enclosed in a tube made of sugar cane to dispose of everything in the most ecological way possible.

In the rugged and often unpredictable environment of a mine site, success hinges not just on machinery and minerals, but on the skilled hands and informed minds of the workers who navigate this challenging terrain daily. Every individual, from seasoned professionals to newcomers, must be equipped with a robust skill set that encompasses technical knowledge, safety protocols, and the ability to adapt to ever-changing conditions. This article delves into the essential skills that form the bedrock of effective mine site training, spotlighting the myriad ways in which these competencies not only enhance personal performance but also contribute to overall operational efficiency. With safety as a top priority, workers must cultivate a deep understanding of both their craft and the environment around them—ensuring that each day spent underground is not just productive, but also secure. Join us as we explore the vital skills that empower workers to thrive in one of the most demanding industries in the world. Safety Awareness and Practices Safety awareness and practices are paramount in the realm of mine site training, where the stakes are incredibly high and the environment can be unforgiving. Workers must be equipped with not only knowledge but also a keen sense of vigilance, as hazards lurk around every corner. From understanding the proper use of personal protective equipment to recognizing the subtle signs of potential emergencies, every detail matters. Regular drills can make the difference between a minor incident and a catastrophic event; thus, being prepared and responsive is crucial. Moreover, fostering a culture of safety through open communication and teamwork amplifies overall site awareness, encouraging everyone to speak up about unsafe conditions or practices. In an industry where lives depend on each other’s actions, being proactive about safety isn’t just a priority—it’s a responsibility that every worker must embrace. Operational Skills and Technical Knowledge Operational skills and technical knowledge are the backbone of a worker’s effectiveness at a mine site. Mastery of heavy machinery, for instance,doesn’tt merely involve knowing how to operate equipment; it requires a deep understanding of the mechanics behind it, the environmental factors at play, and the safety protocols that govern its use. Workers must be adept at troubleshooting issues on the fly, from adjusting hydraulic systems to recognizing potential failures before they escalate into dangerous situations. Furthermore, proficiency in reading geological maps and data analysis enhances worker’srs capability to navigate the complexities of mining operations. This blend of hands-on skills, technical insight, and critical thinking fosters an environment where every worker can contribute to achieving operational efficiency while ensuring safety and compliance. Ultimately, it is this comprehensive skill set that distinguishes successful mine workers from their peers, enabling them to adapt and thrive in a demanding and ever-evolving landscape. Effective communication skills are paramount in the high-stakes environment of a mine site, where clarity can mean the difference between safety and disaster. Workers must not only convey their tasks and concerns succinctly but also actively listen to colleagues and supervisors, fostering an atmosphere of mutual respect and collaboration. The nuances of verbal and non-verbal cues add layers of complexity; a nod, a gesture, or even a pause can carry significant meaning in this dynamic setting. Beyond mere exchanges, strong communication involves problem-solving conversations and conflict resolution, ensuring that every team member feels heard and valued. Training programs should emphasize these skills, incorporating role-playing scenarios and real-life examples to prepare workers for the intricacies of on-site communication. By honing these abilities, employees contribute not only to the success but also to the collective efficiency and safety of the entire operation. In conclusion, equipping mine site workers with essential skills is crucial for ensuring not only their safety but also the overall efficiency and productivity of mining operations. By focusing on comprehensive training programs that cover operational procedures, emergency response, and safety protocols, companies can foster a culture of safety and competence among their workforce. One pivotal component of this training is the Mine Site Safety Supervisor course, which prepares individuals to take on leadership roles in maintaining safe work environments. Ultimately, investing in these essential skills not only enhances individual performance but also contributes significantly to the long-term success of mining operations.

We’ve provided information below to give you insight into a number of dental related matters. We hope it is helpful. Just click any subject below to reveal more details… If you’d like to know more about anything at all, just get in touch! Tooth whitening (bleaching) is a totally painless and simple process which will make your teeth lighter and brighter and will give you something extra to smile about. The process is completed in the comfort of your own home and usually takes about two weeks although results can be seen in just a few days. This treatment can also be used to change the colour of individual teeth and in many cases can be an alternative to veneers or crowns. Ask your dentist if this treatment would be suitable for you when you are next in the practice. When you lose one or more teeth and you want to replace them but don’t want to wear a denture a bridge may be the answer. A bridge is a false tooth or maybe a few teeth which are attached to adjacent teeth to act as a permanent replacement. Once cemented into position you clean and brush it like a natural tooth and it doesn’t need a plate to hold it in place. Archaeological evidence shows that the first bridges were constructed thousands of years ago by the Egyptians who used fine gold wire to fasten human or animal teeth and white stones onto their other teeth to fill spaces. Modern bridges you will be pleased to know have come on a fair way since then and it is now often possible to replace a missing tooth in such a way as to make it impossible to tell. There are many variations of bridges, most conventional bridges are held in place by a crown or crowns on adjacent teeth but there is a type called a Maryland bridge which is simply bonded into place with a resin cement. The advantage of this is that it is simple, inexpensive and doesn’t involve preparing other teeth but it is only really suitable for front teeth and it isn’t as strong as the conventional type of bridge. If this idea appeals to you, ask us to investigate if you would be a suitable candidate. Ancient Egyptians used fine gold wire to fasten animal teeth into their mouths to fill gaps! In recent years things have moved on!! Good tooth brushinq techniques The average ftime that people brush their teeth for is 45 seconds, and it is totally ineffective. Electric tooth brushinq We recommend electric tooth brushes as the best method. They have a very efficient cleaning actiocarder models have a two minute timer, that ensures the teeth are brushed for long enough. The technique is very different from that for manual tooth brushing. Just put the brush in contact with the tooth-gum margin and follow the contour of the tooth round to the next one. Let the brush do the work for you. Brush each tooth individually, not as a “row of teeth”. Ask for a demonstration next time you are in the practice. Manual tooth brushinq The technique we recommend is called the Bass mini scrub technique. This involves carefully placing the bristles on the gum margin, pointing 45 degrees up for upper teeth or down for lower teeth, and gently but firmly move the brush backwards and forwards, no more than a centimetre at a time, keeping the bristles in contact with the gum margin. After a few seconds of this carefully roll the bristles away from the gum edge then start again with your toothbrush centred on the next tooth. Gradually work your way around your mouth. Inside and out, top and bottom. As a private practice we are able to spend the time necessary to provide you with the highest quality of treatment and advice. At your initial consultation appointment we will almost always be able to provide you with a detailed written estimate of any dental treatment, which may be necessary. In more complex cases we may require a couple of appointments to fully investigate the treatment options and discuss the costs and implications with you. Because we do not rush you in and out of the surgery, you can expect to be at the practice for about half an hour on your first visit. We will also ask you to fill in a confidential medical history form, which we will normally post to you when you book your appointment. Once we have completed any initial treatment required we generally recommend Denplan care to help you improve your long term dental health and as an excellent way to budget for any future costs. Along with this we recommend regular check-ups every three, six or twelve months to enable us to detect minor problems before they become major ones which means treatment is kept to a minimum. We believe very strongly in regular monitoring of your total oral health. We will advise you of the recall interval we feel is appropriate for you. We will only start treatment with your consent and usually only because it is urgent. We do not rush you in and out of the surgery. You can expect to be at the practice for about half an hour on your first visit. One of the most common problems we encounter in modern dentistry is how to treat a cracked tooth. With today’s lifestyles of eating healthy foods (muesli, granary bread, etc) with lots of hard bits in it, high stress working environments (many of us grind our teeth, often at night as a stress relieving habit) and the way we now retain our habit) and the way we now retain our teeth longer, often for life. This means lots of often heavily filled and weakened teeth enduring heavy strains and workloads for many years. It is hardly surprising that cracked teeth become a problem, normally starting from the third decade of life. Many teeth have superficial cracks in them which are visible but of no consequence. These are thought to be caused by thermal cycling. (Hot drinks then cold air or ice cream, throughout your life.) However if the crack becomes deeper and enters the dentine layer, symptoms will occur. This happens mainly in back teeth. It may start as sensitivity to hot and cold things, or pain when biting crunchy things. The treatment is to reinforce the tooth across the line of the crack. This may be done by use of a white (bonded) filling, or a crown. If the crack is severe it may injure the pulp (nerve) within the tooth and cause an abscess. At this stage the tooth may require a root filling. Ultimately the crack may propagate right through the tooth causing a fracture of one or more cusps and depending upon the depth of the fracture this may result in the tooth becoming unrestorable. Although most cracked teeth can be treated simply and successfully, a small number (10%) will cause persistent problems and will ultimately require extraction. Cracked teeth are unpredictable and it often takes a lot of time and effort to diagnose and treat them successfully. What are composite fillings? These are an alternative to conventional silver fillings. In the right place they are hard wearing and look like a natural tooth. Advantages of composite fillings - A moderate sized white filling can increase the strength of the remaining tooth making it less likely to fracture in the future. - They look better than conventional silver fillings, in fact in some cases they can be virtually indistinguishable from natural tooth. - In some cases the better thermal insulation provided by non-metal fillings can make a tooth less sensitive. Disadvantages of Composite fillings - White fillings may not be suitable if the cavity is too big. - Proper placement requires the site to be kept isolated of saliva. This can be difficult in very large cavities near the back of the mouth. - They are not suitable if the cavity is deep enough to go below gum level. - White fillings take longer to place. Our practice policy is to use white fillings in cases where we would expect them to last at least as well as a silver amalgam filling but not if we feel the result may be compromised by moisture control or other clinical factors. This sometimes means we have to make a final decision when the filling is being placed. Your monthly Denplan Essentials payment will give you a 10% discount of our filling fees. What is a dental crown? A crown (often called a cap) is a tooth shaped covering that encases the tooth on which it is cemented. Crowns are used generally when the damage or decay is so extensive that filling materials cannot make the tooth strong enough. They can also be used to improve the appearance of teeth. They are a long lasting and durable way to restore a tooth. How are crowns prepared and fitted? A crown is provided over two visits. At the first appointment the tooth is filed down to make room for the crown. An impression of the tooth is then taken and a temporary crown is placed. The impression is then sent to the dental laboratory for construction of thev permanent crown, which generally takes about two weeks. At the second appointment the temporary crown is removed and the newly constructed permanent crown is cemented onto the previously prepared tooth. There are many different types of crown available with differing aesthetic and physical properties. We will always explain the choice of material we wish to use for your teeth and allow you to make the final decision. Very strong even when in thin section. Aesthetic but fragile. Only for front teeth. Quite good aesthetics and fairly strong. A good standard restoration. High strength ceramic Strong and beautiful but expensive. What is a denture? A denture is a removable replacement for missing teeth. It is made from acrylic resin (a type ofhard plastic) sometimes incombination with various metals.Complete dentures replace all the teeth whilst partial dentures replace some missing teeth and prevent the remaining teeth from moving. Dentures can improve chewing ability, speech, and provide support for the facial muscles. They are also important in maintaining and improving appearance. Newer materials now available can restore appearance so that others cannot tell you are wearing dentures. How are they constructed? Dentures usually require about 4 or 5 surgery visits. Initial impressions are taken of your teeth and gums and plaster models are made in the dental laboratory. The dental technician then makes a wax rim for the dentist to register how you bite. This is returned to the lab and it tells the Botox technician how your top and bottom jaws meet. It will also give him/her information on how much tooth you will show and how your lips are supported. It is often a good idea to bring and old photo of how your teeth looked before you lost them. Teeth are then added to the wax and tried in the mouth to gauge appearance and fit. We will check first for technical accuracy then let you see how the new denture looks. If you have any concerns about the appearance please let us know at this stage and we can change things very simply. A further try-in stage may be required. The denture is now finished in the laboratory and is ready to be fitted… You go away wearing it Subsequent visits may be necessary for adjustments as the dentures “bed in”. It is particularly true in children but also with adults, if you are having problems with tooth decay it is probably your diet that is at fault. To take this further it is not only what you eat and drink but the way you consume it. We are all aware that sugar, cakes and sweets are bad for our teeth but there are many other less obvious foods which can cause decay. Tooth decay occurs when we eat and drink incorrect foods but the risk of decay increases if we eat them frequently. This means opening a packet of sweets and eating one every few minutes throughout the day will cause more decay than if we eat the whole packet all at once. Just half a tsp of sugar in hot drinks throughout the day still creates an increased risk of decay. We recommend that food or drink which is likely to cause tooth decay is eaten straight after main meals. This cuts down the amount of times food is eaten which will result in less decay. There are no safe snacks in between meals, milk or still water are the only safe drinks. Diet soft drinks are extremely acidic so even though they contain no sugar they are just as harmful as the regular type of drink. Even natural fruit juice and cordials are extremely harmful! I often look at what people have in their shopping trolleys at supermarkets for the weekly shopping and I am stunned by the quantity of soft drinks, biscuits and sweets most families consume. The British Dental Health Foundation estimated that a tax of just 2% on this sort of product would fully fund private dental health care for the entire population of the UK. How much do you spend on this sort of product? When our first permanent molar teeth come through at approximately age six you can see a pattern of grooves and fissures on the biting surface. In many cases these are the weakest part of the tooth. In conjunction with the limited cleaning abilifies of the average six year old and the sweet diet that children often have, these fissures are generally the first part of a tooth to decay and need filling. To protect this weak part of the tooth, we can bond a thin layer of plastic over the fissure. This prevents the bacteria and sugary foods from getting into the fissure and causing decay. Once the tooth has been sealed it should be monitored regularly to check its integrity. Fissure sealants can reduce the occurrence of decay by up to 80%. Placing a fissure sealant is a quick and painless way of protecting a tooth. It is normally done shortly after the tooth erupts and requires some cooperation from the patient so may not be possible for all children. Gum disease effects 99.9% of the population at sometime in their lives. Left untreated it may develop into Periodontal disease which may result in the loosening and loss of healthy teeth. Plaque is a soft film of millions of bacteria which grow in the mouth. It is extremely sticky and white in colour which makes it difficult to see against white teeth. Plaque collects and sticks around the gum line where the gum meets the tooth. If plaque is not brushed away at LEAST once in 24 hours, then it produces toxins which cause the gums to become inflamed, red, swollen and sometimes painful. Gums will bleed when brushed, this is known as gingivitis. The Plaque will then begin to harden and form calculus (tartar) this cannot be removed with a toothbrush and you will need a scale and polish which your dentist/hygienist will do for you. At this stage gingivitis is reversible and with good teeth cleaning techniques and effective removal of plaque taught by your dentist/hygienist the gums will become healthy (pink with no bleeding on brushing) within a few days. Our Hygienists our professionally trained in the role of prevention and treatment of tooth decay and gum disease for adults and children. As dental therapists they will advise you on teeth cleaning techniques and dietary advice which is tailored to your specific needs. This will involve a combination of electric and manual tooth brushing and the use of dental floss or inter-dental brushes to clean even the most inaccessible spaces. In the surgery the hygienist will scale and may polish your teeth to remove stains and tartar (calculus) build up which cannot be removed with your toothbrush. Measurement of gum recession will often be recorded to monitor the progress of any gum disease in your mouth. The hygienist can apply Fissure sealants (thin plastic coatings) to weak surfaces of teeth, especially for children, to help prevent cavities. No matter how hard we try to save your teeth and no matter how well you look after them, sometimes teeth need to be extracted. When this happens one option to replace the tooth is to insert an implant into the jaw and then fit to crown over this. An implant is a titanium screw which is placed into the bone of the jaw in a simple surgical procedure. The bone then heals around the implant until it is held fast. Then the top of the implant can be exposed and a crown may be fitted. Some of the advantages of implants are that they replace the root of the tooth not just the crown therefore a better gum contour can sometimes be achieved than with conventional methods. Modern implants have a very high success rate. Implants retain the bone around an extraction socket. Best results are often obtained by placing the implant within a few months of the extraction. Possible disadvantages are complicated to complete and are correspondingly expensive. They are not necessarily suitable to replace multiple lost teeth. They need excellent oral hygiene to maintain them. They are not suitable if you srnoke. In some parts of the mouth there are other anatomical structures which prevent the placement of an implant. An inlay is a type of filling made in the laboratory. They have been made from gold for many years however more recently they have been fabricated from high strength porcelain materials. Gold inlays are the strongest type of filling and this is sometimes important. Porcelain inlays again are very strong [although not as strong as gold] and can sometimes be used in situations where a conventional white filling cannot be used. They are very aesthetic and can make a heavily filled tooth look like new again. They do however take two visits to complete and since they are made in a laboratory they are considerably more expensive than the more usual type of filling. (pronounced LY-ken PLANE-us) What is it? Lichen Planus in the mouth can affect the inside of the cheeks, the tongue or the gums. Usually it appears as white lines or patches, which are occasionally sore, but severe cases can lead to raw, red areas or ulcers, which may be painful. It is relatively common and occurs most often in middle aged adults (slightly more women then men). It is not a progressive condition and although it may persist for several years, it usually becomes less active with time, eventually burning itself out. In about 1 in 5 people with oral lichen planus the skin is also affected, with itchy purplish scaly patches, particularly inside the wrists and ankles. It may affect the genital area as well. What causes it? The exact cause is unknown, although sometimes certain medications can cause a reaction similar to lichen planus. Otherwise it is thought to be “immune related” I.e. the white blood cells attack normal parts of the skin or mucous membranes (instead of responding just to injury or infection). Because it is not an infection, it is not contagious. It is not a cancer, it does not appear to be inherited and it is not directly related to nutrition. What make it worse? - Certain foods e.g. wines/spirits, citrus juices, coffee, cola and spicy/crispy foods. - Mild trauma, such as rubbing on sharp teeth or fillings. - Poor oral hygiene. - Contact with amalgam fillings (not proved). It is usual to confirm clinical diagnosis with a biopsy. This sometimes reveals a fungal infection, which requires anti fungal medication before a re biopsy will detect underlying lichen planus. It also provides a baseline for any changes seen in the future. (blood tests may be taken). Biopsy is minor procedure carried out in the department using local anaesthetic to numb the area to be sampled, after which dissolvable sutures are placed. Occasionally the healing areas can be quite painful for several days, so we recommend that you don’t plan any important activities during this time and suggest using painkillers and mouthwashes as necessary. Mouth Cancer during Lockdown If you are worried that you have mouth cancer, get in touch with us immediately. Referrals for mouth cancer are still available and we will be able to give you all sorts of advice and help to come to an understanding of your problem. Signs and symptoms to look out for are: - A non-healing ulcer in your mouth. If an ulcer hasn’t healed after 3 weeks, it is considered suspicious. (not an ulcer caused by a sore denture or a sharp edge of a filling or broken tooth) - A red, white or speckled patch on the mucosa. This includes the gums, tongue, roof of your mouth, cheek linings and lips. - A thickening or lump in your mouth - Difficulty or pain with chewing, swallowing or speaking - A lump in your neck - Sudden unexplained weight loss - Bleeding or numbness in your mouth If you experience any of these please contact us as soon as possible. We will arrange a remote consultation immediately. You may want to look here for more information. This is a reputable source. Mouth Cancer Facts Mouth cancer can develop in any part of the mouth including the tongue, gums, tonsils, lining of the mouth, lips and upper part of the throat. The early signs of mouth cancer can often be seen. When changes are found early there is a very good chance of a cure. This page tells you about the changes to look out for and who is most at risk. Who is most at risk? Our lifestyle choices have a big effect on our risk of mouth cancer. The most important causes of mouth cancer are… - smoking tobacco (cigarettes, cigars, pipes) - regularly drinking large amount of alcohol - chewing tobacco or betel nut People who use tobacco and drink too much alcohol have the highest risk of mouth cancer. Up to three-quarters of mouth cancers are caused this way. Mouth cancer is more common in men than women and is rare in people under the age of 40. Early detection saves lives It is important to notice changes inside your mouth. Tell your doctor or dentist if they last longer than three weeks. Early treatment is simpler and more effective and many people can be cured. What should I look out for? Look for the following changes. They may not be painful but you should still see your doctor or dentist if they last longer than three weeks. The most common signs of mouth cancer are… - an ulcer or sore in your mouth or on your tongue - a red or white patch in your mouth - an unexplained pain in your mouth or ear Other signs to look out for are… - an unexplained lump in your neck - a sore or painful throat - a croaky voice or difficulty swallowing If you notice any of these changes and they last longer than three weeks, tell your doctor or dentist without delay. Usually they are not caused by cancer but it is better to play safe. Checking your mouth Sometimes the early signs of mouth cancer do not cause pain or discomfort but they can be seen. So it is important to check your mouth for any of the changes. From time to time, spend a few moments in front of the mirror looking in your mouth. Check your tongue, gums, lining of your cheeks, lips, under your tongue and the roof of your mouth. But remember your dentist can easily check the parts you cannot see. Your dentist can help Dentists have special training to help them identify health problems and are often the first to spot early changes in their patients. As part of a regular examination, dentists check for the early warning signs of mouth cancer. They will refer patients with suspect changes to hospital. There are many different mouthwashes and generally we do not recommend you to use a mouthwash since they are of debatable value and are an expensive way to freshen your breath. There are however some specific situations where therapeutic mouthwashes can benefit. Colgate Fluorigard, Plax and Mcleans iviouthguard are some examples. We recommend you Talk to either the Dentist or Hygienist about these mouthwashes. Also try the Alcohol Free alternative. These are of benefit if you are at particular risk from decay (cavities). This may be due to an unsuitable diet, congenitally weak teeth, or more often factors such as poor ability to clean your teeth (arthritis, broken arm, stroke etc.) or gum recession which exposes the roots of your teeth which gum recession which exposes the roots of your teeth which are more susceptible to decay. Usually you should change the cause [if possible] as well as using the mouthwash. Listerine, Listermint, Freshbreath, etc. We recommend don’t bother! The effect of these is very transient; they are of NO benefit in removing plaque and helping to clean your teeth. In effect they make you feel you are doing something and make your teeth feel clean although they are not That slippery clean feeling is achieved by the use of detergent. It does not clean your teeth. If you want to freshen your breath and can’t manage to clean your teeth with a brush try SUGAR FREE GUM & MINTS OR SUGAR FREE STRIPS. However do not be under the impression that you are cleaning your teeth! Therapeutic Chlorhexidine Gluconate: This is the only mouthwash which has any significant action against the bacteria in your mouth. Daily use is highly effective to prevent and control all types of gum disease, however, it also causes severe staining of your teeth. Therefore we recommend that you only use it when we advise you to and for short periods only Hydrogen Peroxide mouthwash which is effective against many bacteria which cause gum disease. It is only a “help” as correct cleaning techniques are far more important for the control of gum disease. Try Sensodyne gentle, Gel Kam or Duraphat toothpaste. These are all high fluoride products which reduce sensitivity when used on a regular basis. However we do not recommend you to use Sensodyne or similar products on a regular basis unless you discuss it with us first. Click here to find out more about Sensitivity. If gingivitis is left untreated it may develop into periodontitis. Periodontitis has all the symptoms/signs of gingivitis but deteriorates further as plague bacteria slides down the tooth root, underneath the gum and starts to rot away at the bone which holds the tooth in. This causes the gum to split away from the tooth and form deep pockets which may result in gum abscesses, gum shrinkage (recession) and finally loose or drifting teeth. Tooth roots will become exposed making them more susceptible to root decay and sensitivity. You are at an increased risk to gum disease if you smoke, are stressed or take some prescribed medications which are known to irritate gums. Treatment of Periodontitis As periodontitis becomes worse it is important to establish the seriousness of the disease. Your dentist/hygienist will measure the gum pockets so the progress of deterioration of the disease can be monitored. Treatment of periodontifis involves education, enabling you to effectively clean plague bacteria from the base of deep pockets ONCE A DAY. Then your dentist/hygienist will clean and scale the teeth and all exposed root surfaces in order to remove calculus from above and below the gum line. This calculus is rough and traps live plague bacteria which will cause further disease. It is possible to halt the progress of possible to halt the progress of periodontifis up to a point, but if too much bone is eaten away this is much bone is eaten away this is irreversible and will result in tooth loss. What is a root filling and why might I need one? A root filling is required when the nerve in a tooth dies. This may happen for a number of reasons. The nerve often dies in heavily filled teeth, or if a tooth is knocked in an accident. Teeth with big cavities or broken teeth may also cause the nerve to die, this often, but not always, presents as an abscess with pain and for swelling. At this point you will need either a root filling or extraction of the affected tooth. A root filling is the process by which the dentist removes the dead or dying nerve from the centre of a tooth (root canal) then cleans, files and shapes the root canal to get rid of any infected or potentially infected material. Then fills it with an inert, radiopaque root filling (usually gutta percha, which is a rubbery material). Once this has been completed the tooth is ready for a filling or a crown to rebuild it to full form and function. Root filled teeth tend to be rather brittle so a crown is often the preferred restoration since this can re-enforce the tooth to some extent. This is one of the most common types of dental treatment. The intention is to remove all of the build up of plaque (live bacteria) and calculus (the calcified remains of dead bacteria) from your teeth. Unless this is done your teeth and gums will remain infected and may develop gingivitis or periodontitis. In most cases we will use a sonic or ultrasonic scaler to do this. These instruments can quickly and effectively remove all the debris from your teeth and will leave a smooth and clean surface which can restore the health of your gums. These instruments use effects called cavitation and micro-streaming to clean. These are techniques which are used in many other processes in a wide range of scale from cleaning barnacles off the hulls of ships to cleaning the inside of delicate laboratory instruments. It is a very effective but also very delicate way of cleaning your teeth. Traditional hand scaling may sometimes be used for particular individual situations but hand instruments do not flush away the debris as well and will not be able to remove calculus as efficiently as mechanical devices. We will sometimes polish your teeth to remove superficial stain and soft plaque. We may decide not to polish your teeth if no stain is present and especially if you suffer from sensitivity or abrasion. Sensitivity is the single most common problem in dentistry. At some point in our lives we will all suffer from sensitivity. Sensitivity may range from mild (it is normal to feel the cold if you eat ice-cream or in severe weather) to the extreme. (You may suffer severe pain from drinking a lukewarm beverage or when brushing your teeth.) The most common cause is receding gums. This can be caused by gum disease or by brushing your teeth too hard. When the gum recedes it exposes dentine which may be very sensitive to hot, cold or sweet stimuli. Treatment is to apply a variety of desensitising materials until the pain reduces and eventually goes away. You must also stop the cause of sensitive teeth or the problem will return. If it returns it means you have treated the symptom but not the cause. This may mean changing to a more suitable toothbrush, changing your brushing or flossing technique or changing the toothpaste you use. Your dentist or hygienist will be happy to advise on your individual requirements. Sensitivity can also be caused by a cavity developing in one of your teeth or by a very deep or broken filling, a failing crown or a cracked tooth can also cause sensitivity. If the nerve in a tooth starts to die and form an abscess the first symptom may be sensitivity. If you suffer from persistent sensitivity ask your dentist to investigate it with you. You don’t need to put up with it! In most cases sensitivity is easy to treat however sensitivity may be the first sign of an abscess developing. Silver Amalgam fillings have been used in dozens of countries around the world for over a century. Amalgam is a very well tolerated material and has been amazingly successful over this period of time. There have been some concerns raised in recent years about the safety of amalgam, since it contains mercury. However there is no independent authorative evidence to suggest that there is a link between silver fillings and mercury toxicity. This is despite the fact that there are millions of amalgam fillings in the UK alone, and that these have been present in some cases for many decades. Having said that, I still prefer to use non mercury fillings where they are suitable, however this is not always possible and I personally adopt a common sense approach to the issue. If a white filling can be used I will use it, if for clinical reasons it is not suitable I will use amalgam. This is the same rationale I apply to myself if ever I need one of my fillings replacing. If you feel strongly about this matter please discuss it with us and we will try to come to a treatment plan which will accommodate your concerns. This however may involve using porcelain or gold inlays or crowns instead of a simple filling, where necessary. You will be surprised how much sugar there is in seemingly “savoury” foods compared to obviously sweet foods… Here are a few examples. 1 Packet of Oxtail Soup = 6 tsp of sugar 1 Tin of Tomato Soup = 2 tsp of sugar 1 Tin of Baked Beans = 4 tsp of sugar 1 Tin of Sweetcorn = 3 tsp of sugar 4 tbl of Muesli = 3 tsp of sugar 1 Glass of Lucozade = 7 tsp of sugar This is exactly the same as refined sugar and will still cause decay in your teeth. Natural sugar occurs in all fruit. The other problem with many foods is that they are naturally acidic. This means they cause damage to your teeth even more quickly than sugary foods. You can measure the acidity of a product by the PH value, the lower the PH the higher the acidity. Here are a few examples. Anything less than 5.4 causes damage to your teeth. Having acidic drinks at mealtimes makes them less harmful and continuous sipping is more harmful than consuming the whole drink at once. Drinking through a straw can also reduce the contact between the acidic drink and your teeth. It is also good practice to rinse your mouth with water when you have finished drinking soda. Lemonade, orangeade, cola, etc. (sugar and sugar free) PH 2.7-3.2 Sugar free whole orange drink E.g. apple, mixed fruit, rosehip and hibiscus PH 3.0-3.2 Still PH 7.6 Sparkling PH 5.4 Lager/Bitter PH 4.0 Red Wine PH 2.5 Cider PH 3.2 Every time you eat or drink anything containing sugar or anything acidic, it damages your teeth. How much damage depends on the frequency and how resilient your teeth are. There is a bewildering array of toothbrushes available today, which one is right for you? - A small head- most of us will naturally choose a toothbrush with a large head. This is the first mistake. About 2 cm long is the best length for most people with an average size mouth ranging up to 3cm if you have a large mouth. - An oval head without any sharp edges to catch your gums. - A handle that fits comfortably into your hand. - Most importantly the correct bristles… “Soft” or “Natural” bristles can’t remove the build up of plaque from your teeth. “Hard” bristles will damage the delicate gums and cause recession. This leaves us with “Medium” bristles. These must always be nylon and we find that most reputable manufacturers use the same stiffness of bristles for all their main range of brushes. Again, ask your dentist or hygienist which toothbrush is right for you. We are very keen on using electric rechargeable toothbrushes. They produce a vigorous but controlled cleaning action which can’t be improved upon by manual brushing. Whilst many people clean their teeth excellently with a conventional toothbrush we feel it is easier, faster and more sustainable to get the cleanest teeth with an electric brush. Ask us for a recommendation next time you are in the practice. We sell a wide range of manual and electric toothbrushes at prices that always compare very favourably with the high street. Why do we need to take x-rays? We may sometimes want to take one or more x-rays of your mouth. This is to give us important extra information, for example to spot decay underneath old crowns or fillings or to assist with completing a successful root filling. How often do we take x-rays? How often we will want to take x-rays will depend on a variety of factors. Usually we would need them at your first visit to the practice or if you have not been for a long time. After that we assess how much of a risk of decay your teeth are and take some x-rays to monitor progress about every 6 month to 3 years. We will always need x-rays to enable us to carry out root fillings or the removal of wisdom teeth and we also need a recent x-ray before preparing a tooth for a crown or bridge. Many patients are concerned about their exposure to x-rays at the dentist and we too share this concern which is why we limit the number x-rays we take to a minimum and only to obtain essential information. We use the latest x-ray equipment which is checked monthly and certified every 15 months to ensure that it complies with current legislation. This means that the lowest possible x-ray dose is used every time we take a film. - We use very narrow beam (only 6 cm wide) so only the area we are interested in is exposed. - The x-rays beam is filtered so that all the ‘soft’ harmful radiation is removed, since we only need the ‘hard’ relatively harmless radiation for x-rays of teeth. - The X-ray “dose” from one small film is about the same as you get from 6 hours background radiation. (The natural radiation you experience all day, everyday, wherever you are.) We use the latest x-ray equipment which is checked and certified every 15 months.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
Life during the Middle Ages was hard. People were always at war. Therefore, castles were built to protect people from their enemies. The castle was the home of a lord and his family. It was also the home of the soldiers. The soldiers were there to protect the castle, the load and his family. They also protected the village from attack. The castle was also the prison and the treasure house. It was even the center of local government. Most castles were built on a hill or high ground. This made the castle easy to defend. A moat ( a deep ditch filled with water) was built around the castle. A drawbridge, which could be raised and lowered with winches and chains, lay across the moat. During the Middle Ages, most castles were built in the shape of a square. They had a large tower in each corner. These towers were usually made of stone. A thick stone wall ran from tower to tower and formed an area called the inner ward. A large central tower was called the keep. This was always the very strongest part of the castle. The load and his family lived on the upper floors of the keep. The soldiers lived on the lower levels. The keep had many secret rooms and getaway passages. It was here, in the keep, that all the village people would hide during times of great danger. There were many underground tunnels leading to the keep. The other towers were used for the prison. The great hall was the place for town meetings. The kitchen and bake shop were also part of the castle. The space outside the towers and wall was called the outer ward. This outer ward was surrounded by another wall. This second wall also ran around the whole village. The top of this wall had a walk for the soldiers and battlements (high stone shields). From behind the battlements the soldiers could hide and shoot their arrows and cast stones at the enemy. At the end of the Middle Ages, castles disappeared. They were replaced by forts. But many rich homes, homes of loads and earls, were still built in the shape of a castle. Castles have always held the interest of people. Even today in European countries the old romantic castles are a big tourist attraction. Many people flock to see these buildings of time.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
In the hot sun, the sandstone layers of the canyon were like melting Neapolitan ice cream, the strawberry of the Jurassic entrada liquifying under the weight of vanilla and chocolate. I followed a slim trail of pink puddles through archways of junipers and found myself in the landscape depicted in Georgia O’Keeffe’s 1940 painting Untitled (Red and Yellow Cliffs), a trippy oil that shows the precipice that towers over her beloved Ghost Ranch topped by a tiny slice of blue sky served à la mode. A cloud of bushtits led me to a boulder that had calved off the pastel canyon rim. It was rough as sandpaper and festooned with an eight-inch lizard. She basked in the Southwest rays doing push-ups, displaying her fierce black-and-yellow stripes. When she raised her chin, the powder-blue underside contrasted with the pink hue of the boulder, a color combination that haunted me with visions of viral gender-reveal parties. How did I know that she was a she? I had stumbled across the internet’s “gay icon” of herpetology: the New Mexico whiptail. Over the past decade, Cnemidophorus neomexicanus has become an idol for some queer people, because this species’ members are all female. They reproduce asexually through a process called parthenogenesis and yet still display sexual behaviors like mounting. They’ve thus been dubbed the “leaping lesbian lizard” and inspired art, comics, a Pokémon named Salazzle and shelves of online merchandise — even the name of an ultimate frisbee team at Wellesley College. One sticker sold on Etsy portrays two lizards in the seven colors of the Sunset Lesbian Pride Flag, their tails curled in the shape of a love heart. Over the past decade, Cnemidophorus neomexicanus has become an idol for some queer people, because this species’ members are all female. Simply put, parthenogenesis is reproduction without fertilization, Hannah Caracalas, a biologist and board member of the Northern Colorado Herpetological Society, explained. She told me that the process is relatively common in plants, as well as invertebrates such as scorpions, but rare in vertebrates. It does occur in some fish, reptiles and birds; in fact, it was recently observed in a pair of female California condors, though these New World vultures primarily reproduce sexually. Parthenogenesis, however, is well known in certain species of whiptails, including the nearby Colorado checkered whiptail (Cnemidophorus tesselatus), whose reproductive behaviors Caracalas has studied. “There are a series of hormonal triggers that happen around reproduction time that signal to the female to start producing these eggs,” Caracalas said. “She basically copies her own genetic material and passes it off to her offspring.” This means that the mothers and daughters are all clones of each other — they have identical genetics. While the lizards reproduce fully on their own, the New Mexico whiptail and Colorado checkered whiptail both engage in pseudocopulation, in which one lizard mounts another, bites, and hooks its leg around the bottom lizard’s body, while the two lizards entwine their tails. “It is thought that that kind of behavior will start stimulating those hormonal triggers that will lead to ovulation,” said Caracalas. When I found a second whiptail on the south face of the Ghost Ranch boulder, I thought of my dry biology classes in high school and college, and how they were framed through a cisgender and heteronormative bias that excluded the full reality of the natural world: Not all species reproduce via male/female pairs. Many species, in fact, including New Mexico whiptails, lack males altogether, and others, like some marine snails, change genders to mate. This same prejudice has been propagated by everyone from historians and academics to Hollywood producers, who have straight-washed queer people and their relationships, from Susan B. Anthony to the artist Mai-Mai Sze and her partner, Irene Sharaff. Whiptail fans joke on online message boards that the cis-het male biologists of yesteryear must have described the New Mexico whiptail as “a species consisting entirely of good friends and roommates.” “Our understanding of same-sex sexual behavior in animals has really shifted from when I was a queer youth in the ’80s,” said Karen Warkentin, a professor of biology and gender and sexuality studies at Boston University. In the past, Warkentin added, information about queer biology was “actively suppressed,” and scientists were discouraged from studying it. Today, however, many scientists conduct research without these biases, opening the door to a truer understanding of biology. Take the common name of the mourning gecko, an all-female parthenogenetic species native to Southeast Asia. According to Reptiles Magazine, it comes from a clicking sound they make at night; biologists assumed that they were “mourning” over never having a male mate. As if. That clicking, along with head-bobbing, is actually a primary form of communication for mourning geckos. A recent study published in Life Sciences Education showed that biases like this in biology courses impacted queer students’ sense of belonging and career preparation. By erasing the truth of diverse genders and orientations in nature, this bias helps bigots spread the lie that queerness in humans is “unnatural,” an errant choice. It’s reminiscent of today’s book bans, which label queer texts as profane in a homophobic effort to skew how we view the world. One of the first things that they teach you in a college biology course is that there’s always exceptions to the rule and that nothing ever fits into nice, neat boxes. But today’s scientists are studying and communicating nature to the public as it is. Caracalas, who has been a lizard lover her entire life, said she discovered that she was a lesbian around the same time she began studying the Colorado checkered whiptail. Observing the lizards in the field brought her immense joy at a formative time. “Biology has been used as such a weapon against (queer people),” she said. “But ironically, one of the first things that they teach you in a college biology course is that there’s always exceptions to the rule and that nothing ever fits into nice, neat boxes.” Warkentin believes that the New Mexico whiptail inspires the LGBTQ+ community partly because its complex biology has been studied and communicated so effectively by scientists. For me, learning about New Mexico whiptails has not only anchored me more firmly to the high desert landscape we shared that afternoon, but given me yet another example of how the natural world can shatter human prejudices. In short, these lizards have radicalized me. Miles W. Griffis is a writer and journalist based in Southern California. He writes “Confetti Westerns,” a serial column at High Country News that explores the queer natural and cultural histories of the American Southwest.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
Refugees, in order to survive, have been forced to flee their countries throughout history. Such was the case with five year old Stephanie and her 9 year old sister who fled Nazi Germany in 1938. Born of a Jewish father, their mother put them on a kindertransport, a train for children refugees that would take them from Vienna to England. They weren’t alone – nearly 10,000 primarily Jewish children – were welcomed into the United Kingdom. Stephanie, of course, had no understanding of what was going on, what this England place was or why she and her sister were sent there. What she came to realize is that the foster family who took them in, helped save them from the holocaust. Even at a young age, this fact would have a major impact on Stephanie’s life. Having been saved through the generosity of total strangers, she became determined to show that her life had been worth saving. That she would certainly do. She had an interest in science and a particular passion for mathematics. Those subjects weren’t readily available to females in those days – but she was determined to pursue her desired studies. Performing well on assessments, she was allowed to take several courses in math and science at the local school for boys. Upon graduating, she went to work rather than pursue a university education given the limited science curriculums available. Instead, she went to work at the Post Office Research Station. There, she helped to build computers from scratch and programmed them using machine programming. At the same time, she pursued a mathematics degree in night school. She moved to the private sector, going to work for CDL Ltd., a computer development company. It was there that she first experienced the ‘glass ceiling’. It was the 1950’s. She would not tolerate being hugged or pinched – behavior that was deemed ‘normal’ at that time. More so, she realized that she had advanced as far as she ever would – entirely because of her gender. By 1962, she was married, and with the full support and encouragement of her husband, decided to start her own business. Her concept was truly unique and well ahead of its time. Her company would sell software, a concept considered foolish by most. In those days, software was given away as an inducement to purchase the hardware. Stephanie knew there was an evolving need for custom software. Hers would be a company of women – bright, talented and smart – who, like herself, stayed home to raise children. With that, she launched Freelance Programmers. She pioneered flexible scheduling and embraced a ‘trust the staff’ approach. As a female, she faced challenges which no male had to deal with. After discussion with her husband, she began to use the name Steve in her business dealings. Letters were answered. Doors were opened. The surprise that he was a she, quickly evaporated when business needs were met. The company’s output required extensive coding. Programming was in its infancy at that time which resulted in the company and its employees becoming coding trailblazers. It was this team of women that created the first ‘black box’ for the Concorde. Stephanie – Steve – decided to give 25% of the company to her staff, at no cost to them. In 1975, Britain passed an Equal Employment Opportunity law, which had the ironic consequence of forcing Steve to hire men – but only highly qualified men. The company continued to grow. By 1996, this female owned company started with ‘bizarre concepts’ was valued at $3 billion. Seventy of the staff had become millionaires as the result of the ownership stake they were given. Those results were realized because Dame Stephanie ‘Steve’ Shirley is a fearless brand. Fearless Brands are both determined and persistent What an incredible legacy Dame Shirley would have created if the story were to end there – it doesn’t. Steve, as she very comfortably goes by today, was nowhere near finished with her life’s purpose. She and her husband had a son, Giles. At the age of two and a half, he changed into an unmanageable toddler and lost what little speech he had. It was then that Giles was diagnosed as profoundly autistic. Giles became the first resident in the first house in the first charity that Steve created. She became a pioneer in the development of services to support autism. She went on to start more homes, schools, research facilities – whatever she could do to fill any gap in services for the autistic. Most recently, she’s started a three year think tank on autism. Giles died in 1998. Steve’s love for her son and her commitment to address the impact of autism have not – and will not – waver. The Oxford Internet Institute (OII) is another of Steve’s initiatives. Its mission is to study the social, economic, legal and ethical ramifications of the internet. OII is a department of the University of Oxford which is committed to the social science of the internet and is focused on research, teaching and policy. Today, Dame Shirley is 82 years old. Her determination and persistence are as strong as ever. She is truly a fearless brand and someone from whom we can learn a great deal Embrace what drives you – Dame Shirley enthusiastically embraced her new country, becoming a patriotic citizen of Great Britain. She has an appreciation for the generosity of strangers and a country which open its arms to people in need which as she says “Only someone who’s lost their human rights, can understand”. She was able to discover her purpose in life at a very early age – prove that hers was a life worth saving. Do you know what drives you? Do you know your purpose? If so, embrace it every day – if not, find the key which will unlock that power. Make yourself invaluable – She half-jokingly says that she has no fear of ever being lost, because if she went missing “several charities would quickly come to find me.” Be so committed to what you do – to your purpose – that your absence couldn’t go unnoticed. Doing so isn’t difficult when you know your purpose – when you embrace your passion. The magic is in making things happen – Ideas are great says Steve. What’s essential, however, is making it happen. That takes a relentless energy, strong self-belief and determination. It requires courage and a willingness to accept failure – on your path to success. If you know your purpose, but aren’t ‘making it happen’, you need to either reignite your energy or redirect your efforts. What an amazing gift the world received when a young refugee was welcomed by a country and embraced by strangers. You can’t replicate exactly the ground-breaking and innovative path that Stephanie ‘Steve’ Shirley blazed. You may not become worth $1.5 billion or even live to 82 and beyond. But you can learn from her, adopt her traits, be inspired by her and build yourself into a fearless brand.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
"And the light shines on in the darkness, but the darkness has not mastered it." John 1:5 Depression and its affects can be a devastating blow to anyone. It is invasive and can take a person from standing tall in their life to hunched over, mentally and physically, rapidly. It is not our fault when we struggle with depression, but it becomes our responsibility to decide what we will do with it--or won't. Left untreated, depression can cripple us, but there is hope--even the creation can help us battle against depression. But what is depression? Depression is a mood disorder that can affect people of all ages and backgrounds. It is estimated that over 300 million people worldwide suffer from depression, making it one of the most common mental health conditions. That is a lot of people doing battle against their depression daily. While there are many treatment options available, there are some things a person can do on their own that might help when they are struggling. It has been found that something as simple as spending time in sunlight can help alleviate symptoms of depression. Sunlight is a natural source of vitamin D, a nutrient that plays an important role in regulating mood. When we are exposed to sunlight, our bodies produce vitamin D, which can help boost our mood and reduce symptoms of depression. In fact, research has shown that people with depression are more likely to have low levels of vitamin D. In addition to its mood-boosting effects, sunlight also helps regulate our circadian rhythms, which can have a big impact on our mood and energy levels. Our circadian rhythms are our body's internal clock, which tells us when to sleep and wake up. When we are exposed to sunlight during the day, it can help regulate our circadian rhythms, which in turn can help improve our mood and energy levels. ***It's important to note that too much sun exposure can also have negative effects on our health, such as increasing our risk of skin cancer. It's important to strike a balance between getting enough sunlight to benefit our mood and overall health, while also protecting our skin from harmful UV rays. But, that's what life is all about right? Trying to find the balance. If you're struggling with depression spending more time in sunlight could help. Here are some practical tips to consider when being in the light: Start small: If you're not used to spending time in sunlight, it's important to start small and gradually build up your exposure. Start with just a few minutes of sunlight each day, and slowly increase your exposure over time. Protect your skin: Always wear sunscreen and protective clothing when you're spending time in sunlight, especially during peak sun hours. Find ways to incorporate sunlight into your daily routine: Whether it's taking a walk outside during your lunch break or sitting outside to read a book, finding ways to incorporate sunlight into your daily routine can help improve your mood and overall well-being. Consider light therapy: If you live in an area with limited sunlight or have difficulty getting outside, light therapy may be an option. Light therapy involves exposure to bright, artificial light, which can help regulate your circadian rhythms and improve your mood. Find something you enjoy: With depression, it can be difficult to want to do anything. Making time outside coincide with something you have found joy in in the past can help make it easier to get yourself outdoors. You can also weigh the effort it takes to get outside and do your activity with the payoff after you spend your time outside to see the benefit for yourself. Just the doing of things when you are depressed can have a major impact on the level of depression you are experiencing (for more information on this look at Behavioral Activation Therapy). While sunlight may not be a cure for depression, it can be a helpful tool in managing symptoms and improving our overall well-being. Coordinating other activities such as therapy and doing the things that we don't feel like doing with our time outside can cause a turnaround where there once seemed no hope. If you're struggling with depression, it's important to talk to a mental health professional and explore all treatment options available to you. Please reach out to The King's Forge Counseling via our contact form at www.thekingsforge.net to set up a time to talk. And don't forget to walk in the light, it will help you see more clearly!

ACT for the Human Habitat To enable coatings that will transform the human habitat, the three ACTs take advantage of the versatility provided by polymers, nanoparticles and their mixtures to create coatings with tailored chemistry, surface texture and function. By imbuing coatings with structure and function via tailored chemistry, surface texture, or by embedding (nano)particles, we design active coating technologies (ACTs) to transform passive surfaces into functional devices. These ACTs address societal needs impacting humanity on a global scale, including access to clean water, prevention of the spread of disease, and the creation and storage of energy. To have maximum impact, we aim to design these active coating technologies to be inexpensive, achievable over large surface areas, and implementable under challenging settings, wherever humans reside. As a central theme, we focus on sites of natural disaster, where clean water, sanitary conditions and energy are in short supply. Our technologies will also have transformative impact in the rehabilitation of old/outdated buildings, making them more self-sustaining and energy-efficient without the need for complete re-construction. To achieve these goals, we have assembled an international team of scientists and engineers with complementary expertise from the US (Penn, ASU, Villanova, BMC) and GIANT (Grenoble, France) and its six affiliate institutions. To enable active coatings that will collect and filter water, ACT 1 seeks to understand how the length scales, geometry, and surface energy of hierarchically structured coatings influence equilibrium and non-equilibrium wetting, droplet growth and water transport. To enable active coating technologies that suppress surface-mediated transmission of disease, ACT 2 aims to relate surface mechanics, texture (ACT 1) and biomolecule density/orientation to the adhesion, proliferation and killing of microorganisms. Perhaps the most challenging aftermath of a natural disaster is the need for energy in the form of electrical power. ACT 3 is focused on ACTs for light harvesting, energy conversion and storage. ACT 3 develops flexible coatings to enhance solar light collection based on semiconductor and organic-inorganic perovskite nanoparticles doped with rare earth elements. ACT 3 also aims to develop the next generation of solid polymer electrolytes for lithium ion technology. Five unifying principles integrate the three ACTs to create a unifying environment within which to train scientists and engineers and to enrich our research. The first principle is the commonality of materials and approaches; all three ACTs utilize hybrid, structured coatings comprising polymers, textures and (nano) particles. The second principle is the importance of theory and simulation to guide research by focusing on relevant parameter spaces, for example, appropriate particle type, size, shape, and surface chemistry. This approach will predict the assembled particles/polymers structures that directly impact behavior, including wetting, bacteria adhesion, and energy conversion. The third principle unifying the ACTs is a common need for mechanical characterization and robustness; to be effective, advanced coatings technologies must be robust under environmental stress (strain, humidity, temperature). This is particularly relevant near sites of natural disasters. Promising coatings will undergo in-situ nanomechanical measurements so that structural changes can be correlated with changes in their function. The fourth principle is the novel methods for film characterization afforded by the partnership with GIANT, particularly ILL and ESRF for neutron and x-rays methods, respectively. Of all potential collaborators in the world, GIANT is uniquely positioned as an international partner because of the co-existence of all the necessary expertise and one-of-a-kind facilities in one city and the collaborative atmosphere that already exists among the GIANT-affiliated institutions. The fifth principle is the shared aims to translate our findings into applications in collaboration with our industrial partner, Solvay.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
At the American Translators Association Conference in Washington, DC, I attended a session on Interpreting and Translating for Farmers and Migrant Workers presented by Michelle Pinzl. This is the target audience of some of my translations, and knowing who we translate for helps us write in a way that our text is understood. When I can, I review the draft of my translation with the target readers. This post will be a brief overview of Ms. Pinzl’s presentation with some of my conclusions. She has kindly allowed me to share her PowerPoint. Farmers and Migrant Workers Distributed According to the 2013-14 National Agriculture Workers survey, there are 2.5-3 million agricultural workers. Data submitted at the attached ATA presentation give the following statistics regarding migrant farm workers: · 16% identify as migrating · 84% are seasonal workers · 73% are foreign born · 68% were born in Mexico · 31% said they speak English well Who is a Limited English Proficient Individual according to the US Federal Government? Individuals who do not speak English as their primary language and who have a limited ability to read, write, speak or understand English can be limited English proficient, or LEP, entitled to language assistance with respect to a type of service, benefit or encounter. See item IV on page 41459 of this link. 48% have an education of up to 6th grade. Therefore, written materials addressed to this population need to be: · Well written in English so they can be translated easily. Following the Five Steps to Plain Language to reach a 6th grade level on the Flesh-Kincaid scale (available on Word) will help. · In plain language in Spanish, making use of graphics, bulleted lists and charts to clarify the message. Reaching a 6th grade audience in Spanish will be a simple task when the document has been prepared for this purpose in English. This means that when specialized terminology is introduced, it should be explained. Studies have shown that reading comprehension is reduced when stressed, ill, or reading on the computer. Considering these factors when preparing good source materials for translation to Spanish will also improve services to English-speakers. The risk of a bad translation in this sector is high. A bad translation can cause confusion in the best of circumstances. As an interpreter, I have heard administrators tell people to ask their elementary school children to sight translate documents into English for submission to administrative offices. I have also seen Spanish-speakers decline translated materials with spelling and punctation mistakes because they do not trust the accuracy of the translation. In those cases, poor translations communicate disrespect and burn bridges instead of building them. The LEP community needs to work with certified interpreters and certified translators as often as possible. We can’t afford to garble the message when communicating with a vulnerable population. The first step, however, is for translators to receive carefully written materials, prepared with this audience in mind. This will benefit the community at large in all languages, even in English.

In school, I was advised not to pursue a career in teaching as “I did not look like a teacher”. I still remember how deflated I felt and as a result was determined to become a teacher and never make a student of mine feel inadequate. To this day, I do not know what a teacher is supposed to look like, nor should it matter. What does matter is that a teacher has the ability and interest to instil a self-belief and self-confidence in their students, so they can develop into the best possible person they can be. They may not be successful the first time round, and may have to work harder and longer to achieve success, but with the right support, they can achieve their desired goals. It is unnerving to consider the potential impact – both positive and negative – a teacher’s words can have on a student. A female student who wishes to pursue a career in computer games development may be told to consider nursing, “a more suitable career for a woman”; a male student, who wishes to pursue a career in early childcare education, may be asked “is he sure he wants to spend all day with small children?” Such words can sway the choices of individuals and cast doubts on their own personal career preferences. Imagine the result if the female was encouraged to study and work in the gaming sector, which is almost totally male-dominated? She would be a role model for other potential female games developers. If the male was encouraged to follow his preferred career, he too would be a very positive role model for young children. Students should be encouraged and supported to follow their dreams and passions when it comes to career choices with the support of their teachers. The power of positivity and encouragement is miraculous. It can result in the transformation of doubtful students to empowered individuals.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu
The recent 2018 Midterm Election has resulted in having 112 women as elected officials (25% of the of the total 435 representatives who have ‘seat, voice and vote’. To pass any legislation requires 218+ votes. With their 237 Democratic majority, the Democratic Party will select the Speaker of the House and will be in charge of the agenda, setting priorities and schedules. Now the House Republican Caucus is 98% WASP (white Anglo-Saxon Protestant) males. The House Democratic Caucus numbers 38% WASP males. Elected women have not yet reached parity levels (50% men: 50% women). This nation’s population has 48% males plus 52% females. No population survives biologically when men exceed women or when women’s fertility rate declines below the replacement level needed to sustain a population. Stanford University population biologist (Paul Ehrlich: The Population Bomb author) has established that a couple needs to beget more than two children to sustain a nation’s population with their consensual reproductive efforts. A committed couple initially may agree to consensual recreational sexual relations with the woman using birth control to schedule family planning. These couples may become fully engaged in establishment of their career paths. An observation is that the three types of man-woman relationships (most often marriages) are: 1) matriarchy; 2) patriarchy and 3) partnership. Of the three, the partnership relationship seems to be most stable and productive. Biologically, men tend to be physically larger & stronger plus assertively competitive, even aggressive behavior traits essential to empire building. Women tend to be nurturing, protective, and desire having a stable relationship in a safe, secure home. Having a child means a woman deals with a reproductive process which includes 9-month gestation period plus 18 years of being the mom until the child is of legal age (18 years old). Being a consensual partner requires an ability to listen, to take-in other experiences and points of view. Individuals, at first are competitive, but the most successful are those who communicate well, negotiate, and know when to stop being competitive. A transition to a reliably mutual supportive and cooperative relationship results which requires constant attentive maintenance. I observe DEMOCRACY is a very good governance system when most, if not all, these traits are present in elected officials who make public policy decisions when dealing with humanity’s needs fairly and with equity. With all the current human reproductive biology knowledge, it is now possible for governance to contain both the male and female perspectives and sensitivities. Those leaders who take into consideration the needs of those being governed, and who reasonably distributed available resources and services were the most successful and highly revered. Jesus Christ began social inclusiveness with compassion for the gentiles who did not have Roman Citizen status enforced by Roman military forces of that era. It was the Christian philosophy of being a ‘Good Samaritan’ who looked out for and took care of the disabled and needy which began establishment of a higher level of Christian behavior. (All religions and cultures consistently deal and promote appropriate behavior and sharing resources amongst individuals and communities.) The Christian Bible contains many anecdotes which involve women…beginning with Adam and Eve. Other biblical women are Esther, Salome, Sara, and Mary who agreed to conceive, carry & deliver, and nurture Jesus Christ (with the support of Joseph, her husband) through his formative years. It is the mother who gives her child, while nurturing and nursing, its first relationship experiences language & vocabulary, a sense of safety and belonging, and appropriate & essential behavior and survival skills. It is these direct experiences which are lacking when men govern exclusively. I recall reading about an American indigenous tribe whose governance was totally conducted by men whose wives sat behind them during powwow discussions regarding tribal issues. These women directly communicated their perspectives and concerns immediately to their partner sitting before them. American society, economy and government, since its inception during 1770’s, has been dominated by WASP men who led this nation’s geographic and economic expansion. All through these periods, work done by women was facilitated by the development of appliances (vacuum cleaners, dishwashers, clothes washers, blenders, etc.). These provided additional opportunity for women to learn at all levels of science, technology, math, engineering, finance, etc. In addition, traditional women’s work as ‘home-making’, teaching, literature, nursing and child-rearing expanded. Today, it is possible for women to aspire to be astronauts, engineers, lawyers, physicians, and YES…even elected officials at all levels (local, state, national, international) of government. Women achieved the right to vote (19th Amendment; 1920) with the result that traditional governance by men exclusively is reluctantly yielding to including more women as elected officials. Many men like Donald Trump had power, authority, and dominion; who were allegedly physically and verbally abusive to women; and whose actions and statements were recorded using smart digital devices and disseminated to the general public via mainstream media and social media…all resulted in the women’s marches and “Me, Too” movement. It is these movements, coupled with women’s suffrage that enables able women to become elected officials. The House of Representatives, US Congress, will have the highest number of women ever elected to that level of legislative responsibility. Speaker of the House Nancy Pelosi is already providing advice regarding how not to be pushed around by Congressional men & lobbyists. These females need to function as PEERS to men who traditionally have not experienced any female colleagues. IT IS VERY IMPORTANT THAT THESE WOMEN EXPRESS DOMESTIC NEEDS FROM A MOM’S EXPERIENCE AND PERSPECTIVE. These newly elected woman members of the U.S. Congress will have to provide direct ‘seat, voice and vote’ decision-making authority based upon their humane nurturing instincts flavored with compassion and consideration. I project that the present influence of the military-industrial complex will be mitigated. It is the sons and daughters of women who are placed in harm’s way by the current knee-jerk military reaction strategy. Also, The Department of Defense will have to implement national security programs with more fiscal accountability and responsibility. If America is to achieve even greater international prominence (which has declined under the Trump Administration), it will be due to the propensity of women to communicate, negotiate, and compromise with logic and values using factual, truthful, and useful information. A transition may happen with regard to undertaking programs addressing Global Climate Change; creation of a shared global resources economy by using diplomacy. War-like police actions are wasteful of resources needed to provide education, medical care, housing, transportation, etc. A goal would be to utilize natural resources to sustain the common good and world peace which ‘We, The People’ crave. Many philosophers and economists have projected that this planet Earth can provide for all the needs of all humanity to live a comfortable life. What needs development to get there is a new distribution of wealth system which provides an assured annual personal income (aapi). All stakeholders would pay appropriate tax levels which enables government jurisdictions to monitor, assess, and distribute needed resources while holding down costs of necessary deterrent military forces. America can lead the way to enduring world peace and prosperity. A goal is to create heaven on this earth using resources already provided by Divine Providence.

Air travel has come a long way since the Wright brothers made their first successful flight in 1903. Over the past century, technology has played a crucial role in shaping the evolution of flights and transforming air travel into what it is today. One of the most significant advancements in air travel technology is the development of jet engines. Jet engines revolutionized air travel by allowing planes to fly faster, higher, and more efficiently than ever before. This innovation paved the way for commercial airlines to offer faster and more affordable flights to passengers around the world. Another key technological advancement that has transformed air travel is the introduction of computer systems and automation in aircraft. Modern airplanes are equipped with sophisticated computers that help pilots navigate safely through complex airspace, monitor engine performance, and optimize fuel consumption. These systems have greatly improved Book a flight safety and efficiency, making air travel one of the safest modes of transportation. The integration of digital communication systems has also had a profound impact on air travel. Pilots can now communicate with air traffic controllers in real-time using digital radios and satellite-based communication networks. This allows for better coordination between pilots and ground control, resulting in smoother take-offs, landings, and overall flight operations. In recent years, advancements in materials science have led to lighter and stronger materials being used in aircraft construction. This has allowed airlines to build more fuel-efficient planes that can carry more passengers over longer distances while reducing their environmental impact. Furthermore, developments in aerodynamics have led to the design of more efficient wings and fuselages that reduce drag and improve fuel efficiency. These innovations have helped airlines reduce operating costs while offering passengers a smoother flying experience. The rise of digital technologies has also transformed how passengers book flights, check-in for their journey, access entertainment during flights, and stay connected while onboard. Mobile apps allow travelers to book tickets instantly from anywhere around the globe while online check-in services streamline boarding processes at airports. Looking ahead, emerging technologies such as electric propulsion systems are poised to revolutionize air travel once again by reducing carbon emissions from airplanes significantly. Electric-powered planes could usher in a new era of sustainable aviation where environmentally-friendly flights become a reality. In conclusion, technology continues to drive innovation in air travel by making flights safer, faster, more efficient, comfortable for passengers worldwide. As we look towards future advancements like electric propulsion systems will continue shaping how we experience flying for generations to come as technology evolves further into unknown territories within this industry’s landscape – creating endless possibilities!

It is getting more expensive to run a car especially with the current price of fuel. You can improve your fuel consumption by adopting a “greener ” approach to your driving. Driving with empathy for the car, fuel consumption and the environment. A regularly serviced engine (as per manufacturer’s recommendation) will optimise fuel/engine performance and in the long run will save money on fuel and increase the life of the engine. Your tyres should be kept to the manufacturer’s recommended pressure. Too low and extra road surface contact will create drag and the friction will reduce fuel consumption. The life of the tyre will be reduced. Too high and the tyre will wear excessively in the middle and give a less comfortable drive. Avoid carrying unnecessary items in the car. More weight equals more fuel. The faster you travel the more air resistance. This in turn leads to increased use of fuel. Eco-driving is now being recorded on driving tests. Your ability to drive smoothly avoiding excess acceleration and braking. Using engine braking where appropriate. Using the gears in a controlled manner at the correct speed to optimise their use. Planning ahead and anticipating problems to avoid any late or over reaction. The outcome of a driving test will not be effected. However this is a pilot scheme and could well be introduced as part of the test in the future. DID YOU KNOW… As a new driver, you will find it easier to get the feel of the foot controls if you wear thin-soled shoes or trainers. The correct way to use the clutch is to bend the knee and keep the ball of the foot on the pedal. Your heel should lift off the floor as you raise your foot to find the biting point. Using your ankle to pivot upwards is awkward and difficult to control. Moving off smoothly and manoeuvring the car at slow speed becomes difficult. You will find yourself having to wriggle your foot back into place at regular intervals. Sometimes when trying to select reverse gear – it will not go in! It is not you! The gears do not always line up. Select a forward gear and try again. This time you should succeed. The car is on springs for a smooth ride – the suspension. When you stop the car on a hill it sinks on its springs. To find the biting point for an uphill start without fear of rolling back, feel the car lift (on its springs) and you have the weight of the car. You will not roll back. The Driver and Vehicle Standards Agency has recognised steering safely and in control does not necessarily mean a fixed routine of holding the steering wheel at ten-to-two or feeding the steering wheel through your hands at all times without crossing your arms. There are times when a more relaxed grip and crossing your arms can be more appropriate during slow paced manoeuvres for example. Steering with one arm only and letting the wheel slip through your fingers after a turn does not however constitute control. The examiner is looking for controlled steering following the correct line during a driving test with some flexibility as to how you do it. Oversteering on a bend is caused by steering the front of the car and not the wheels. The two do not point in the same direction on a bend. Steer the wheels and allow the front of the car to follow, this will help to stay with the curve. Dry steering (turning the steering wheel while stationary) is okay providing your vehicle has power-steering. Sometimes you need to, to recover from a manoeuvre. You will not be penalised on a driving test. When slowing down you do not have to change down through the gears 4-3-2-1. Apply the brake and select the gear to match the slower speed when you know what it is. If you are stopping, just apply the brake followed by the clutch. You can select neutral once you have stopped. You are not expected to select neutral gear every time you stop temporarily. You have enough to do especially as lead car waiting at traffic lights. You can remain in 1st gear (preferably without biting point for too long), handbrake applied if needed. Traffic lights are sometimes fitted with visors to avoid confusion where there is more than one set of lights close together. It could be dangerous for an approaching driver to see both red and green lights showing. One set of lights is visored, fitted with narrow slats and angled to obscure the projected light at a distance. Close up they can be seen from the lower line of sight. Before pulling away from a bus stop the bus driver applies the footbrake and then releases the handbrake before signalling. In other words the brake lights come on before the right indicator flashes. (This is a built in safety feature for automatic vehicles and modern buses are automatic). It does not happen like that every time but it is a very useful clue if you are considering passing the stationary bus. Flashing headlights should only be used to advise or warn other roadusers of your presence. However, it is a means of communication and should not be ignored if a driver flashes at you. Make sure you interpret it correctly and do make sure you look properly. You cannot rely on their observation if you are invited to emerge for example. Ask yourself:- Is it meant for me? Does it mean what I think it does? Is it safe to accept? Emerging on to a busy roundabout can be a confusing experience. Who’s going where and when? There is a basic rule. You give way to your right and so does everybody else!! Vehicles already on the roundabout will block the flow of oncoming traffic and you may have the opportunity to move forward. Watch their speed and steering, with practise you will get to recognise their intention earlier. Too many drivers forget the basic courtesy of signalling and sadly you cannot guarantee the accuracy of the signal even if they do signal. Their speed and direction are the only sure way of knowing what they are doing. If in doubt don’t! Examiners are examined. You could have a supervising examiner sitting in on your driving test as well as your instructor/observer on test. It would be a good idea to experience somebody in the back of the car in addition to your instructor as part of your training. You will get the feel of the heavier car and how it affects steering, acceleration and braking.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu

Inorganic farming is largely at fault for biodiversity loss, increased water pollution, and soil erosion. Chemical-heavy farming techniques destroy the soil, and the constant introduction of new pesticides generate impervious insects. There are some chemicals the USDA has approved for use on organic farms, but before they can be applied farmers must prove they have tried every other method possible for controlling their pests and weeds. Recycled water from wastewater treatments plants (known as sewer sludge) is used to irrigate conventionally farmed crops. Multi-drug resistant bacteria are found to survive the treatment process and be present in the finished water product. Food crops grow on sludge-applied lands can absorb heavy metals, such as cadmium and lead, which are linked to intestinal and kidney damage. The USDA prohibits sewer sludge fertilizer use on organic farms. Organic farming reduces carbon emissions by 50%, uses less energy due to lack of machinery, and reduces pollution levels by 50%. These good practices actually remove CO2 from the atmosphere. Conventional farming is at fault for causing biodiversity loss, soil erosion, and increased water pollution.

History of Bloomington, Ellettsville & Monroe County, Indiana Monroe County, Bloomington, and Ellettsville are a compelling and unique part of the Midwest, offering solid business and professional opportunities, excellent education, and a fantastic quality of life. Our community enjoys a proud history of industry and education. Known as the "Gateway to Scenic Southern Indiana,” Monroe County was established in 1818 and named after the fifth U.S. President, James Monroe. Before European settlement, the area was home to Native American tribes, primarily the Delaware, Miami, and Potawatomi, who navigated the White River's East and West Forks that inhabited lush forests and fertile lands. Bloomington, the county seat, was founded in 1818 by settlers from Kentucky, Tennessee, the Carolinas, and Virginia. Those settlers were so impressed with "a haven of blooms" that they named the town accordingly. The town of Ellettsville, just northwest, was established in 1837. Because the Indiana State Constitution of 1816 outlawed slavery, and many of Bloomington’s citizens were active participants in the Underground Railroad, the city remains deeply rooted in African American history. Since 1820, Bloomington has been home to Indiana University, now one of the leading public research universities in the United States. IU has dramatically influenced our community's growth and cultural identity, attracting leaders, teachers, entrepreneurs, literary and musical luminaries, professional athletes, and Nobel prize-winning scientists and economists who have shaped the city into a thriving academic and artistic hub. Hoosiers are known for being industrious, and our community is no exception. Our community is one of makers and innovators. We have consistently adapted to changing times to foster new opportunities. In the early years, most people in the area made a living by farming, limestone extraction, and timbering for the furniture industry. The construction of the Monon Railroad in the late 1840s connected the county to major markets, sparking local industrial growth. By 1920, Bloomington made 60% of the furniture in the U.S. Today, that former factory building is an energetic startup incubator called The Mill. In 1940, RCA purchased a Showers Brothers building on South Rogers Street to create RCA Plant One. RCA produced radios, tank transmitters, and receivers for the Army Signal Corps and other defense products in World War II, and then later it transitioned to producing televisions. The rise of industry also brought General Electric, Westinghouse, and Otis Elevator. Since the 1980s, our economy has been moving toward high-tech. The rise of Life Sciences began with Cook Medical, leading to Nova Holdings, (which recently acquired Catalent), Simtra (Formerly Baxter), Singota Solutions, as well as Boston Scientific. That sector continues to grow. Meanwhile, the U.S. Chips and Science Acts create significant job opportunities in the Microchip and Semiconductor industry. At BEDC, the heart of our work is creating economic vitality and quality jobs to ensure Monroe County is Our community of choice for employers, innovators, individuals, and families. Our history has taught us that communities prosper when they foster a vision for the future, lean into their strengths, and coordinate their investments and efforts around that vision.

Water is an essential element for sustaining life. Until recently, it was considered in some circles a natural resource of unlimited supply. However, lately the situation has changed: water has become a scarce resource around the world, including some regions of the United States, with competing interests for the limited supply. One person with a keen appreciation for this is Dr. Harbans Lal, an environmental engineer with the Water Quality and Quantity Team of the Natural Resources Conservation Service (NRCS), US Department of Agriculture (USDA) in Portland, OR. For Lal, food production is paramount to feed the world’s growing population. Lal says, “While we have done an excellent job in increasing land productivity to meet the food and fiber demand, we have not paid enough attention to water quality and have been impacting and affecting it some cases.” He points out that agriculture is the maximum user—at 70%—of available fresh water. “At the same time, agriculture has a tremendous effect on water quality.” To address that, Lal—as part of a USDA-NRCS scientific group—has developed a Web-based tool helping agricultural producers understand the quality of water: the Water Quality Index for Agricultural Runoff (WQIag). It provides a single number from 0 (poor) to 10 (excellent), representing overall water quality flowing off users’ fields, thus making complicated water quality data understandable and useable by non-professionals. Users input information about their field, such as slope, soil characteristics, nutrient and pest management, tillage practices, and conservation practices. It then calculates the WQIag rating. While variables such as slope and soil type won’t change, producers can adjust other factors to quickly estimate how their conservation efforts can impact water quality. What He Does Day to Day Lal says his daily activities center on “working on tools and technologies that can help producers do agriculture with minimal impact to the environment, principally water.” While pollution from point sources such as sewage treatment plants is regulated by the National Pollutant Discharge Elimination System, there are no such regulatory requirements on agricultural runoff from non-point sources. Thus, NRCS bases its work on a voluntary basis, says Lal, adding, “We don’t tell farmers they have to do it. We provide options through conservation planning to help both the environment and productivity.” Lal also spends time interacting with other scientists, reviewing scientific literature, participating in webinars, writing and contemplating how he can best make use of all of the information in designing tools, techniques, and transforming scientific knowledge into a framework which can be easily implemented by the agricultural community. What Led Him to This Line of Work As a youth in India, Lal had not planned to go into agricultural engineering, but his academic path eventually led him to the University of Florida, where he earned a Ph.D. in agricultural engineering. For more than 40 years, Lal has worked in natural resources management, specifically in agricultural systems worldwide, including India, Brazil, and the US. He’s also done private consulting work for many federal agencies. “I keep telling my supervisor I have limited time left on this planet, but I want to make a significant impact in the profession.” What He Likes Best About His Job Lal derives satisfaction through interacting with professionals worldwide. He enjoys working on water-related problems that could alleviate human suffering. He appreciates the freedom of planning his day to perform tasks. His positive supervisory evaluations support that as long as he is making contributions to the overall USDA/NRCS mission. “It’s satisfying if I have contributed something significantly in the professional arena,” he says. His Greatest Challenge Transforming complicated scientific knowledge into something the layperson comprehends in such a way where its real value is not lost is Lal’s biggest challenge. Because of the ‘green revolution’ that enabled agriculture “to do whatever farmers wanted as long as there was high crop production and high yield, we’ve gotten used to using water and nutrients to keep the highest crop yield, not the optimum crop yield,” says Lal. “There is pressure to feed the growing world population, but at the same time, we have to maintain our environment, including water, for future generations.” Carol Brzozowski specializes in topics related to resource management and technology.

Source: Russia in Global Affairs Russian society holds two contradictory attitudes to Islam. On the one hand, according to Nikolai Silayev, “the myth about the ’mysterious East,’ characteristic of Western Europe, never really materialized in Russia: the East has always been considered endemic to Russia.” On the other hand, notions of the “mysterious East” do exist in the Russian mindset, and it is only necessary to consider the many Arab fairy tales, the harems, and the India of Afanasy Nikitin, not to mention Japan and China. And if the Tatars did not pose a mystery, the peoples of the Caucasus and Central Asia posed it. The Muslim East has always been exotic, even if in close proximity to Russia. Islam has at all times been perceived as something alien to Russia on the subconscious level: Muslims live primarily abroad—in the arid Middle East, Afghanistan and Central Asia. This alienated view of Islam was largely promoted by official Soviet propaganda that divided Islam into “foreign,” that is, aggressive, politicized, and occasionally used as a slogan (jihad) in the liberation movement, and “Soviet Islam,” which was related to “backward old men” and “weak women,” and seen as a feudal relic. Needless to say, even then, some intelligent functionaries in the party apparatus and especially in the State Security Committee (KGB) realized that Islam in the Soviet Union had proved to be extremely resilient, retaining its functions as a regulator of social relations. But to reiterate, “Soviet Islam” was not identical to “their Islam,” while the religious identity of Soviet Muslims was regarded as marginal, doomed to extinction. In the late 20th century, following the disintegration of the Soviet Union and under the impact of growing contradictions amongst the Muslim world, Europe and the United States, as well as internal conflicts in Russia, “Russian” Islam began to be increasingly identified with the Muslim world, with all of its strengths and weaknesses. This holds true especially for the North Caucasus—a border area that is a part of Russia and a part of the Muslim world at the same time. The Muslims are perceived as alien or friendly depending on the specific political situation. The war in Chechnya caused the North Caucasus, in the public mindset, to move further away from Russia and closer to the Islamic world. Tatarstan, with its thousand mosques, Islamic University and resolve to adopt the Latin script, is also shifting closer to the world of Islam. Boris Yeltsin’s famous slogan, “Take as much sovereignty as you can swallow,” became a strong incentive for the Muslims to turn away from Russia. The division of Islam into “alien” and “native” remains to the present time, which is especially characteristic of the new official ideology, although today there is a somewhat different emphasis: the qualifier “alien” is applied to Islamic fundamentalism (Wahhabism), as opposed to “native,” or traditional Islam, which maintains a separation of religion from politics and is absorbed into purely religious affairs. The great majority of Russians judge Islam by: - Actions of religious extremists; - conflicts with the involvement of Muslims; - radical statements by Muslim politicians and spiritual leaders; - an influx of immigrants. Very few people have opened the Koran, but yet practically everybody reads newspapers and watches television where Muslims are involved in bomb attacks, wars, and special operations in the North Caucasus, while in news reports, Muslim spiritual leaders are saying uttering banalities. There are several common stereotypes associated with a Muslim: a head-shaven, bearded man with an automatic rifle; a terrorist wearing a facemask; a crooked businessman. It is noteworthy, however, that none of these negative stereotypes are associated with the Tatars, who, in their majority, especially in urban areas, are either close to or indistinguishable from the Slavs by their lifestyle and mentality. The Russian man on the street apparently ignores the Tatars’ Muslim identity: they are just neighbors that everyone has long become used to. “Scratch a Russian, find a Tatar,” as the saying goes. But no matter how hard you may scratch an Orthodox Russian, you will never find a Muslim. The perception of the Islamic world has been aggravated by the 9/11 tragedy, terrorist attacks in Russia and in Europe, and the bellicose phraseology of Muslim politicians. There have been other “incidents” as well, such as the destruction of ancient Buddha statues by the Afghan Taliban (2001), the murder of Dutch film director Theo Van Gogh (2005), the prosecution of an Afghan citizen for conversion from Islam to Christianity, and so on. Pro et Contra In Russia, as everywhere, public opinion is influenced, above all, by crimes committed by Muslims, which are played up in the media. But while criticizing the media, politicians and other public figures for their negative image, it should be noted that Muslims themselves provide cause for their negative perception in the public mind. Even without the benefit of a magnifying glass, it is obvious that Russians have ample grounds for complaints against immigrants from Muslim countries and regions. Meanwhile, attempts by Muslim spiritual leaders to cast Islam as a “world religion” are treated skeptically. First, imams and muftis are usually not eloquent enough to convince the public that they are right. Second, as freedom of expression is suppressed, judgments made in the media receive little credence, as was the case with Soviet propaganda. Third, the deeds of Islamic radicals belie Islam’s purported peace-loving nature in the public eye. Furthermore, Russia has been fighting against Muslims for almost two decades now with little break. Thus, the enemy in the Russian mindset is associated with the Afghan mujaheddin and the Caucasus militant. The present generation of war veterans can rightfully call themselves the “veterans of Muslim wars.” Russia’s attitude to Islam and Muslims also fits into the general context of xenophobia that in the first half of the 1990s was considered to be a hangover of post-totalitarian thinking; 10 years later, however, it has turned into a core element of the public consciousness. Whereas in 1989, some 20 percent of the population showed signs of xenophobia, by 2001 the share rose to 50 percent. According to Lev Gudkov, a well-known philosopher and social scientist, judging by its level of xenophobia, Russia had surpassed even Austria, the most xenophobic country in Europe. A poll conducted by the All-Russia Center for the Study of Public Opinion on Social and Economic Questions (VTsIOM) in March 2002 showed that Russian levels of xenophobia were the highest against people from the North Caucasus (43.3 percent), followed by Central Asia (38.7 percent), and then the Arab countries (30.3 percent). The percentage dropped to 12.6 percent for Belarusians, Moldovans, and Ukrainians. Some 73 percent of Interior Ministry officers were biased against non-Russian immigrants. It would seem that on the issue of immigrants Russia is in the same league with most European countries. For example, according to The Wall Street Journal (December 10-12, 2004), Europeans expressed discontent with the presence of Muslims in their countries (75 percent of Swedes, 72 percent of Dutch, 67 percent of Danes and Swiss, 65 percent of Austrians and Belgians, 61 percent of Germans, 56 percent of Finns, 48 percent of Spaniards, 44 percent of Italians, 39 percent of Britons, and 35 percent of Greeks). Yet it should be borne in mind that in the not so distant past, Muslim immigrants in Russia were Soviet citizens or are still Russian citizens; they speak Russian and can easily adapt to Russia’s cultural environment. Muslims in Russia are “strangers among their own,” while the older generation of immigrants share the same mentality with the Russians. This may bring them closer to the “host nation,” but it can also be an additional source of irritation: “We used to be in the same boat,” some Russians seem to be saying, “but now you are crowding us out, living off us, and getting rich in the process.” Whereas in the past xenophobia was mostly dominated by anti-Semitism, now its principal target are people from the south—70 percent of them being Muslims. Alexei Levinson has noted that “Caucasus-phobia” sometimes affects as much as two-thirds of the population. According to a recent poll conducted by the Yuri Levada Center, Chechens evoked a negative reaction from 52.3 percent of respondents, Azeris from 29.2 percent, whereas Jews from only 11 percent. Jews fought anti-Semitism mainly by leaving the Soviet Union and Russia or, contrary to xenophobic expectations, while preserving their ethnic/religious identity, they integrated into Russian culture, asserting themselves as part of Russia’s new elite. Muslims are not leaving or integrating. Rather, they painstakingly guard their religious identity, and they have extensive experience in resistance, including armed resistance. So, cautious and even negative attitudes toward Islam have a strong base. When asked the question, “Which religion is more alien (hostile) toward Russian Christian Orthodoxy, Islam or Catholicism,” 50.1 percent of respondents mentioned Islam, whereas only 12.3 percent cited Catholicism (Levada Center, 2002). It may be recalled that in a 1994 poll, only 16.5 percent of respondents said they held a negative opinion toward Islam. A negative view of Islam is also cultivated through the dissemination of biased comments by Islamic politicians and spiritual figures. These individuals talk about the inevitable Islamization of Russia, in addition to prospects for creating an Islamic state, which oppose marriages between Muslims and “infidels,” and so on. Xenophobia toward internal enemies is inseparable from xenophobia toward external enemies, but “Americanophobia” is fundamentally different from Islamophobia. The Americans are not feared—they are envied and their lifestyle is imitated. I would describe this as a national inferiority complex because it affects one nation, which in the not-so-distant past was a superpower, in relation to another nation, which is still a superpower. There is no inferiority complex in relation to the Muslim world, although there is a certain measure of irritation over the fact that the former little brothers in need of assistance—Arabs, Afghans, Indonesians, and Central Asians—suddenly grew up and started acting independently. This is incomprehensible, and it inspires fear. Military experts and advisers who worked in the Near East find it hard to understand how the Algerians, Egyptians, Iraqis, Saudis, Yemenis, and others, who had great difficulty studying the military art, were able to produce such a large number of professional fighters (mujaheddin) that caused so much trouble for their former Western and Soviet mentors. To the majority of Russians, however, relations with the Islamic world rank as a very low priority. When asked the question, “What countries should have priority for Russia in the long term,” only 1.8 percent of respondents mentioned Muslim countries, with 40.2 percent giving priority to the CIS countries, 26.2 percent to Western Europe, and 7 percent to China. On the other hand, Russians do not view Muslim countries as a threat to Russia. In a poll conducted in the late 1990s, when pollsters asked people to name states hostile to Russia, respondents in the 17-26 age group mentioned the United States (16.9 percent), Chechnya (13.1 percent), Japan (8.1 percent), Afghanistan (5.7 percent), Iraq (2.9 percent), Turkey (2.6 percent), and Iran (2.1 percent); respondents in the 40-60 age group gave the following answers: the United States (24 percent), Chechnya (8.5 percent), Japan (10.1 percent), Afghanistan (8 percent), Iraq (1 percent), Turkey (1.6 percent), and Iran (2.1 percent). Islam in Print and Electronic Media At the end of last century and the start of this century, media outlets substantially contributed to a religious revival. They helped increase the ranks of believers, shaping their religious identity and encouraging them to observe religious rites. Although this mostly applied to Russian Christian Orthodoxy, Islam was also given some support, but in a rather cautious manner. Whereas the revival of Orthodoxy was encouraged by the state, Islamic revival was permitted. The relatively rapid formation of Islam’s negative media image in the 1990s was due to a rise in nationalism among the Muslims and the ethnic/political conflicts that erupted in the late 1980s, with the conflicting sides often invoking Islam to justify their cause. From the 1990s, Islamic slogans started to be exploited by terrorists. These factors could be described as objective. The main subjective factor was that the difficulties that had arisen in relations with the Muslims quickly evolved into an “Islam scare.” The Islamic factor was blown out of proportion (in the mid-1990s, the war in Chechnya was often referred to as a “conflict of civilizations”); the fundamental concepts of Islam (especially jihad) were distorted; and extremist ideology was extrapolated (purposely or through ignorance) to the entire Muslim tradition. Many Islam-related publications were linked to wars, terror attacks, and armed conflicts. Here are just a few typical newspaper headlines: Islamic Wolves Kill Russian Soldiers; Muslims Besiege the Kremlin; Chechen Whores Blow Up Moscow; The Sword of Islamic Revolution Forged in London. Here is an example of a “model” text: “In the theater center on Dubrovka, not only terrorists and commandos but also Allah and Christ came to blows. Both suffered a devastating defeat” (Moskovskiye Novosti, No. 45, 2002). Russian television also contributed to Islamophobia, and more specifically to Caucasus-phobia. Individuals with a clearly non-Russian appearance are principal actors in such television shows as Criminal Russia, Man and Law, and Emergency Report. A comparison of Russian-made films with European and U.S. films shows that among those who stand up to evil in the Western productions, there are many non-European faces—Africans, Arabs, Chinese, and Southeast Asians, for example. However, in Russian films, exclusively “blond fellows with a Nordic character” fight against the enemy. The Islamophobia component in crime reports and thrillers is not the result of malicious intent, but rather an attempt to assess the global situation, adapt to the public mindset, and boost ratings. On the other hand, cultivation of the enemy stereotype has long been part of the government’s political agenda, even if implicitly. In the past decade, this enemy image has become associated with the international terrorist (i.e., the “evil Muslim”). This was followed, at the start of the 21st century, by restoration of the archetype of U.S. imperialist, allegedly linked with the Islamic extremist. What is even more worrying is that there are virtually no shows on Russian television that provide an honest and truthful account of Islam outside of politics, the “conflict of civilizations,” and so forth. There is a pressing need for objective information. It is also remarkable that in the wake of high-profile terrorist attacks in Russia, no attempt has been made to check the rise of negative perceptions toward Islam. After the bomb attacks in Spain and France, local authorities repeatedly warned the public that anti-Islamism was unacceptable. U.S. President George W. Bush, who in the wake of 9/11 had inadvertently used the word “crusade,” deployed an extensive damage-control effort, talking in favorable terms about Islam and emphasizing the need to distinguish between terrorists and Muslims. Almost nothing of the kind happened in Russia. While I do not think that Russian politicians and media outlets should slavishly copy European and U.S. experience, the fact that Islam remains terra incognita for Russian television must cause some concern: this vacuum tends to be filled with crudely apologetic or, on the contrary, provocative Islamophobic material. Islam in Fiction The Russian people do not only receive their impressions by watching television and reading newspapers; they also learn something about Islam from books. The problem is that the noble characters in the works of Pushkin, Lermontov and Tolstoy have been replaced in Russian pop culture by thugs and sadists. The Russian classics did not idealize “persons of Caucasian extraction,” but they did not turn them into beasts justifying their deeds by references to Islam. Those old books aroused genuine interest in Islam and in its followers; there was no Islamophobia there. According to Yakov Gordin, “the classics and their contemporaries did not see an inseparable wall between two apparently irreconcilable worlds.” The general attitude at that time was: Russia as a great empire was “doomed” to victory, while its adversary was doomed to submit and adapt to it. The empire can afford to be magnanimous toward its new future subjects. This prospect looked fairly optimistic from the 19th century. Today, by contrast, the situation looks murky, to put it mildly. Alexei Yermolov, Pavel Tsitsianov and Mikhail Vorontsov were the past conquerors of the Caucasus. However, considering the tactics being employed by army and police generals today, the word “thug” would seem somehow more appropriate. Meanwhile, an insurmountable wall represents the differences between the Russian and the Caucasus Muslim tradition. Public opinion is becoming increasingly aware of this wall. And pop literature, above all thrillers, provides ample evidence of this awareness. There are series of works where anti-heroes are represented by “persons of Caucasian origin” and where their religious identity is described with references to “jihad,” “Koran,” “infidels,” “Allah,” etc. “Wahit will avenge us,’ he said in a hoarse voice. ’The whole of Russia will be shaken by the hand of Allah!’” (Daniil Koretsky. Kod vozvrashcheniya (The Code of Return), Moscow, 2006, p. 26). This is a good example of the “clash of civilizations” made simple. Actually, thrillers only touch on Islam superficially, as though to remind the reader yet again that murderers and sadists profess this particular religion. Islam is a de rigueur characteristic of anti-heroes. It is noteworthy that more and more often standing behind the backs of Islamic terrorists and extremists are Western secret services, but as of lately, also Georgians and Ukrainians. A case in point is Dzhakhannam, a thriller novel by Yulia Latynina, a political journalist. Judging from the book’s cover, which details a split crescent and a Muslim rosary, with one of its beads shaped in the form of a bullet, it bears all the hallmarks of Islamophobia. The novel attempts to make a separation between the Chechen and Russian criminal underworlds, which live according to their own distinct laws, even though they occasionally cooperate. In these various fictional tales, the Islamic, Caucasian/Islamic, and Western/Islamic threats are primitive but at the same time multifaceted. There are recurring storylines in the Russian version, but also in U.S. and European variety. There is an attempt to initiate a terrorist attack with the use of nuclear weapons (e.g., Daniil Koretsky’s Kod Vozvrashcheniya). In yet another doomsday scenario, Chechen Wahid, a character from Alexander Prokhanov’s book Mr. Hexogen (Moscow, 2002, p. 196), also threatens to blow up nuclear power stations, missile silos and chemical plants. Yulia Latynina is only slightly less bloodthirsty than her contemporaries: the terrorists in her thriller only want to blow up a storage facility with 3,500 metric tons of hydrogen sulfide. The threat of a nuclear apocalypse is present not only in fiction, but is constantly discussed by serious experts, many of whom are convinced that terrorist access to nuclear weapons is only a matter of time. This is a Catch-22 situation: the danger of “Islamic apocalypse” is taken for granted; it is reflected in pulp literature, which inspires the fear of Islam. This shreds the fabric of interreligious accord, which in turn affects the global political situation. In the end, all of these factors can serve to justify preparations for a no-holds-barred, “ultimate” war. Unlike the 19th century, modern literature generally caters to people with “a passive mind,” who are tired and stressed out. They take everything they read for granted. Few readers will take the time to analyze a thriller. This is fertile soil for cultivating a Caucasian/Muslim enemy stereotype. The Islamic theme, however, is not limited to thrillers. In the past few years it has also entered sci-fi literature with an element of political philosophy. All story lines here evolve against the backdrop of total Islamic expansion that some authors see as an apocalypse, while others as geopolitical intrigue, possibly with a favorable outcome for Russia. A “classic” Islamophobic novel in this category is Mechet Parizhskoi Bogomateri (Notre-Dam de Paris Mosque) by Yelena Chudinova. Chudinova describes the triumph of Islam in Paris in the middle of the 21st century. In “Sharia France,” women have to wear the hijab. One street is called Osama. Those who have refused to convert to Islam live in five ghettoes, while practicing Christians are forced to recite their prayers in catacombs, and if discovered face death by stoning. When they learn that the French Muslim authorities are going to destroy the ghettoes, the “non-Muslim” survivors revolt and in the end blow themselves up in the Notre-Dam de Paris Cathedral, which in the last few hours before the destruction regains its Christian identity. The Muslim community ostracized Chudinova’s novel, but the critics missed one important passage that proves the author cannot be dismissed as a “zoological Islamophobe.” She believes that one of the causes of what happened in France, as well as in entire Western Europe, was that the enlightened Muslims who settled down in the Old World were caught unawares by their wild and fanatical religious brethren. It is this fear of “wild Islam” that breeds Islamophobia, sustaining the concept concerning the clash of civilizations. In Chudinova’s novel, Russia survived because it had just barely managed to close its borders to “Euro-Islam.” Following this logic, Russian (Tatar) Islam also saved Russia by its strong immunity to “wild Islam.” But for the average reader, The Notre-Dam de Paris Mosque will only strengthen hostility and hatred of Islam, while a more enlightened reader will replace Paris with Moscow and tremble in horror. Mikhail Veller, Chudinova’s ideological soul mate, sends a disturbing message that the Muslims’ ultimate objective is to destroy the Christian world. “They [Muslims] are stronger in spirit. They are ready to sacrifice more. They sacrifice themselves every day, destroying all those that they consider to be their enemies. They are ready to destroy all of us… They are ready to destroy our culture” (Mikhail Veller, Cassandra, St. Petersburg, 2002, p. 169). Veller’s plan to fight terror is impressive: “All terrorists are Arab Muslims. So if all Arab Muslims are destroyed, there will be no terrorism. Its technological capacity today enables the white civilization to start and win an all-out war with no holds barred.” This passage needs no commentary, except that the author might be reminded that in addition to Arabs, Avars, Dargins, Kabardins, Russians, Tajiks, Uzbeks, Uighurs, Chechens, Americans, and many other nationalities carry out terrorist attacks. Vladimir Mikhailov’s Variant-I (Moscow, 1999) rolls out a whole landscape of a futuristic world. Its storyline is phantasmagoric: Tsarevitch Alexei survives the 1917 execution of the tsarist family and ends up in Iran where he and his offspring succumb to the charms of Islam. In 2045, some international forces (primarily Muslim, but also Israeli) attempt to restore the monarchy and bring it to power in the hope of making Russia an Islamic state. The concept of the future is represented through the eyes of Mikhailov’s characters. Here are some of their judgments: - “Russia needed money and allies to compensate for what it had lost at the first stage after the disintegration, and it found even more than it looked for – in the Islamic world;” - “there is a pressing need for a consensus with the Persian Gulf countries by establishing an international monopoly on oil;” - “nuclear weapons may be transferred to some of our Muslim allies;” - “Islam unites everything; it is more comprehensible to the average believer than the Holy Scripture is;” and - “soldiers professing Islam will never waver.” What impact will this book have on the average reader? Mikhailov uses a potent word in reference to the Islamic world—“Islamida,” apparently to emphasize the omnipotence of this world. But this “Islamophilia” spooks the Russian reader, eventually turning it into Islamophobia. Yuri Nikitin builds a similar concept into his books, Anger and The Evil Empire. According to art critic Leonid Fishman, they present an “Islamic project” that can be summed up as “ideological revenge.” A union with Islam is proffered as the only way of saving Russia. Thus, Russians become the “new shakhids” (martyrs, those who suffer for the sake of principle) and ultimately defeat the West. It is noteworthy that both Mikhailov and Nikitin wrote their novels before 9/11. Presumably, after the tragedy, the idea of Russia forming a united front with Islam can no longer evoke an unequivocally positive response from the reader. Nevertheless, such views remain, and, amid growing anti-American sentiments, are still relevant. Most of the books with an Islamic theme that I have read have one thing in common: today, the Russian state is unable to protect its citizens against violence. It is corrupt and weak, while its officials collaborate with the adversary and are part of the mafia. Needless to say, the aforementioned books are ephemeral with plots and heroes that are easily forgotten. But their judgments, which shape the reader’s image of Islam and Muslims, remain in memory. The main cause of Islamophobia lies in reality, in the events that are unfolding both in Russia and in the world at large: conflicts in the North Caucasus, the rise of nationalism in Russia’s “Muslim republics,” migration, and international and domestic terrorism. The main sources of fear are largely personified in the “evil Chechen” and the “evil Arab.” But the “Islamic threat” is not so much reality as the perception of reality. Cultivated in the media, reflected in artistic forms, and blown up by politicians and clerics, it has become part of the Russian mass consciousness. This refers to the Islamic, not Islamist threat, which really exists. The difference between these two concepts did not begin to be appreciated until recently—due to the efforts of certain politicians, experts, and journalists. As for Muslim immigrants, the general irritation at their presence has little to do with religion. Against this backdrop, books like The Notre-Dam de Paris Mosque look especially provocative. This article has placed an emphasis on the negative perception of Islam. Yet I would like to draw the reader’s attention to the fact that some of the aforementioned figures could have a different interpretation: only 26 percent of respondents said that Islam was an alien religion, while about one-half did not see it as an aggressive religion. We must face the fact, however, that it is unlikely that the negative perception of Islam in Russia will be reversed in the foreseeable future, especially since many factors outside Russia influence this attitude. Everyone is interested in stopping the rise of Islamophobia, not least the Muslim themselves, who should also be more cautious and circumspect, and not speak, for example, about the inevitable “Islamization” of Russia.

At the grand old age of 63, just four years before his death, Karl Blossfeldt produced his first photography book, the internationally best-selling Urformen der Kunst (later translated into English as Art Forms in Plants). The book's 120 plates display Blossfeldt's remarkable photographs of plants – varieties from Equisetum hyemale (Winter Horsetail) to Tellima grandiflora (Fringe cups) — all captured in extraordinary detail, as if under the microscope, frozen into new forms almost beyond recognition. Born in 1865 in Germany’s Harz Mountains, Karl Blossfeldt lived a childhood in the open air. As a teenager he became an apprentice in a foundry making wrought iron grilles and gates, objects decorated with plant-motifs, before then moving to Berlin to study at the School of the Museum of Decorative Arts. In 1890, he moved to Rome to study under the decorative artist Moritz Meurer, where he created and photographed casts of botanical subjects, travelling as far as North Africa to collect specimens. From 1898, and for the next three decades, Blossfeldt taught design at Berlin's School of the Museum of Decorative Arts. It was here, using a homemade camera with custom magnifying lenses, that he first began to take his remarkable photographs, for the purpose of teaching his students about the patterns and designs found in natural forms. Through the technology of photography Blossfeldt was able to reveal to his students details difficult to see by the naked eye. As he wrote in a 1906 letter to the school's director: Plants are a treasure trove of forms — one which is carelessly overlooked only because the scale of shapes fails to catch the eye and sometimes this makes the forms hard to identify. But that is precisely what these photographs are intended to do — to portray diminutive forms on a convenient scale and encourage students to pay them more attention. In light of this mission to reveal overlooked beauty, it is perhaps fitting that Blossfeldt chose not to obtain his specimens from florists or botanical gardens, but rather from track sides and railway embankments, what he called “proletarian areas”. In this sense, the photographs also stand as strange memorials to long-forgotten patches of land. These plants, many weeds, originally "out of place", now find refuge within the corpus of photographic history, immortalised upon the page. When the gallerist and collector Karl Nierendorf came across Blossfeldt’s vast collection of photographs, he sought to publish them — Urformen der Kunst is the result. Though we know only a few hundred images today, largely selected by Nierendorf, it was thought that Blossfeldt had taken as many as 6000, many hung from the walls of his Berlin studio. In his introduction to the first edition, Nierendorf writes that Blossfeldt finds a “happy permeation” of three elements: nature, art, and technology. It is a common trope, oft-repeated in relation to Blossfeldt’s work. According to Hans Christian Adam, Blossfeldt strips nature down. Blossfeldt might have used a fairly basic camera, but the results are startling. The plants become graphic, geometric. One cannot help but draw parallels between Blossfeldt’s Urformen der Kunst and Ernst Haeckel’s Kunstformen der Natur, published a couple of decades prior. In both works, the distinction between nature and art blur. Both depict nature in such detail, with such magnitude, that it appears as almost artificial, as an artwork. Indeed, upon closer inspection it is revealed that Blossfeldt did in fact sometimes retouch his photographs to emphasise and enhance the beauty of the forms he sought to celebrate. Blossfeldt’s work was quiet and unassuming, but it quickly aligned with the avant-gardes of Weimar Germany: from "New Vision" to "New Objectivity". It provided a counterpart in the natural world to what others had attempted to achieve in the excess of the modern city: from the work of August Sander to László Moholy-Nagy. The critic Walter Benjamin was one of the first to review Blossfeldt’s book, claiming his fellow German had discovered the "optical unconscious": that which was invisible to the naked eye, revealed retrospectively or technically through the apparatus of the camera. In this sense, Blossfeldt completes Goethe’s idea of the Urpflanze — a primordial plant that contains within itself an infinity of potential forms: when dogwood becomes a bishop’s staff, when horse-chestnut shoots become totem poles, and the curly stems of the fern become iron railings. It is an art of revelation — "new objectivities" of nature revealed through the camera. Urformen der Kunst was the first of three photo books by Blossfeldt: four years later there came Wundergarten der Natur (1932), and posthumously Wunder in der Natur (1942). All of Blossfeldt's published photographs have been collected in the highly recommended 2014 book from Taschen, Karl Blossfeldt: The Complete Published Work.

Feeling sick lately? Struggling with poor digestion, nausea, or recurring infections? These problems are often caused by exposure to certain chemicals in food, deodorants, cosmetics, cookware, and other common products. Toxic ingredients are lurking everywhere, from water bottles and moisturizing creams to non-stick pans and shampoos. Many popular foods, such as potato chips, energy bars, flatbreads, and deli meats are packed with harmful ingredients. When ingested, these toxins weaken your immune system and cause a host of diseases. Some chemicals, such as those found in cosmetics, are absorbed into your skin. These potentially dangerous household items and foods can affect your health, leading to cancer, DNA damage, reproductive disorders, and digestive problems. To stay safe, avoid these five sources of toxins lurking in your home: High-Fructose Corn Syrup High fructose corn syrup (HFCS) is one of the most dangerous ingredients in food. This sweetener has been linked to heart failure, obesity, high blood pressure, insulin resistance, diabetes, and cancer. Its side effects are well-documented. Regular consumption of high-fructose corn syrup can kill you. This sugar goes directly to your liver where it’s stored as fat. In the long run, it puts you at risk for metabolic syndrome, non-alcoholic fatty liver disease, dementia, and chronic inflammation. It also feeds harmful gut bacteria, which affects digestion. Additionally, many HFCS brands contain mercury and other contaminants that are not regulated by the FDA. This ingredient can be found in most processed foods, from ready-made meals and diet snacks to soda. Cola and citrus-flavored beverages are made with brominated vegetable oil (BVO), a food additive that works as an emulsifier. BVO is high in bromine, the same compound used in plastic goods, flame retardants, and furniture. Studies have linked this ingredient to a high risk of behavioral disorders, weight gain, fatigue, migraines, and memory loss. Even though the FDA limits the amount of brominated vegetable oil in sodas to 15 parts per million, this doesn’t counteract its side effects. According to researchers, BVO increases the risk for cancer of the breast, prostate, ovaries, and thyroid gland. It also causes psychiatric problems, fatigue, and cardiac arrhythmia. Bisphenol-A (BPA), a chemical found in plastic bottles and food cans, has estrogen-like effects, which may disrupt the endocrine system. This compound interferes with metabolic hormones and increases the risk of heart disease, infertility, diabetes, and obesity. Studies have found that BPA is dangerous to human health even at low-level exposure. Millions of people have this toxin in their blood. Fragrances, cosmetics, synthetic leather, and other products contain phthalates. These toxins affect breast development, decrease sperm production, and increase breast cancer risk. Research also shows that people who are constantly exposed to phthalates have higher rates of autism spectrum disorders, neurodevelopmental issues, type II diabetes, and ADHD. The parabens used in shampoos and other personal care products cause toxicity even at low doses. In a recent study, researchers took samples of the breast tissues of 40 patients. Over 99 percent of samples contained parabens. These chemicals have a similar structure as estrogen, causing hormonal disorders, skin rash, irritation, and several types of cancer. The best thing you can do for your health is to use natural products. Eat clean, make your own soaps and face creams, or choose organic brands. Avoid these toxic five in order to detox your body.

Domestic dogs and cats, whether feral or owned, cause the death of millions of wildlife animals every year either by hunting and killing or through disease transmission. The reproductive rates of both species are very high and the current approach of surgical sterilization is too slow and ineffective to have a significant impact on feral cat and dog numbers. The ideal product would be a single dose injectable that causes permanent sterility for cats and dogs of both sexes and that could be administered to large numbers of animals in a short time. Immunocontraception GnRh is a key instigator of both male and female reproduction. The development of delivery systems for continued life long stimulation of antibodies through injectable virus particles is being developed. The virus imbeds itself in muscle cells and produces lifetime antigens. Further reproductive hormones such as Kisspektin (2), FSH, LH or AMH may also be targeted. High dose/long-term GNRH agonist Constant supply of GnRH leads to downregulation of the receptors and a complete cessation of the reproductive system in both the male and female. The already licenced drug Deslorelin works on this principle for 612 months. Attempts are being made to develop new devices to hold and release medication over much longer periods of time. Cytotoxins delivered to specific sites killing cells that are essential for reproduction could be used. The toxin is conjugated to a specific antibody that binds to the target cells. The problem in reproduction is that the target cells are either in the hypothalamus or the pituitary gland and have to cross the blood-brain barrier. Gene silencing/gene therapy A specific protein that suppresses reproduction has to be identified. Delivery of the gene via a virus into the cell for the production of the protein must then be achieved. Gene silencing works with small RNA fragments that are inco-operated into the cells DNA to turn off certain genes (3). This has not yet been attempted with reproductive genes, but in other human diseases.	CC-MAIN-2025-05	HuggingFaceFW/fineweb-edu

Overview

This dataset provides stratified subsets at 50k, 100k, 250k, 500k, and 1M scales, combining high-quality educational web content with mathematical and scientific documents.

Sampling Methodology

Rather than random sampling, we use embedding-based k-means clustering to ensure diverse, representative subsets:

Balanced Sampling: Maintains proportional representation from both FineWeb-Edu and Proof-Pile-2 sources
Embedding Generation: Each sample's text is embedded using Snowflake/snowflake-arctic-embed-xs
K-Means Clustering: For each category requiring M samples, k-means is applied with k=M clusters (100 iterations)
Centroid Selection: The centroid of each cluster is selected as the representative sample, exactly filling the required M samples

This deterministic approach ensures maximum diversity within each category while maintaining balanced distribution—no random sampling involved.
