Anti-Fatigue Lenses Relieve Stress On Overworked Eyes
Spending numerous hours multitasking between your computer, smartphones, tv, and reading materials can make your eyes feel tired and over worked. Hoya, Zeiss, and Essilor have developed revolutionary eyeglass lenses that are specifically designed to complement modern multitasking, tech-savvy lifestyles and minimize the strain placed on the eyes when frequently switching between near (e.g., smartphone) and intermediate (e.g., computer screen) visual tasks. Providing relief from the eyestrain and visual stress resulting from the eyes frequently changing focus between far/intermediate and near activities, anti-fatigue lenses are a real game-changer for anyone who wants to be at their absolute best all day! Whether you're a busy professional, a tech-savvy student, or someone who visually multitasks throughout the day, anti-fatigue lenses will help you say goodbye to blurred vision, headaches, and discomfort, and say hello to a relaxing, enhanced, and energized visual experience.Schedule An Exam Our Optometrists

What Are Anti-Fatigue Lenses?
Technically, anti-fatigue lenses are a single vision eyeglass lens - they contain a single prescription intended to correct vision at all distances, but have a near vision zone (i.e., for activities within 30 cm) with increased magnification, or BOOST in the lower portion of the lens designed to reduce the muscular strain required to focus on near-distance tasks, such as reading or using a smartphone. Similar to progressive lenses, anti-fatigue lenses have no visible line between viewing zones.Schedule A Anti-Fatigue Fitting

How Do Anti-Fatigue Lenses Work?
Anti fatigue eyeglass lenses work by providing a slight magnification, or BOOST, at the bottom portion of the lens. The magnification applied to the near distance zone of the lens is typically selected from predefined options (e.g., +0.6, +0.9, +1.2) by the optometrist based on testing and feedback provided by the patient. The zone of the lens in which the magnification is applied is determined by precision digital measurements performed by our licensed optometrists and opticians. Theses measurements are unique for each individual and eyeglass frame and are essential to providing the best optical performance.Schedule A Anti-Fatigue Eye Glass Consult

Are Anti-Fatigue LensesFor Me?
If you are an individual that spends a considerable amount of time multi-tasking between digital devices or switching between viewing computer screens and reading materials throughout the day, then you will most certainly benefit from anti-fatigue eyeglass lenses. This is especially true if your eyes often feel extremely tired and/or you experience headaches during, or following, extended periods of visual multitasking. Anti-fatigue lenses are generally well suited for individuals between 15 and 40 years of age - individuals that would benefit from easier reading vision, are pre-presbyopic, and do not yet require progressive lenses.Schedule A Anti-Fatigue Lens Fitting

Anti-Fatigue Lenses Are Not Progressive Lenses
Anti-fatigue lenses are often referrred to as baby progressives or introductory progressives, and are often a precursor to progressive lenses. While sharing similar no-line transions between lens zones, tt is important to note that anti-fatigue lenses differ from progressive eye glass lenses. Differences between anti-fatigue lenses and progressive lenses include:
|Lens Type||Single Vision||Multifocal|
|Benchmark Rxs||1 + Boost||3|
|Field Of View||Wide||Narrower|

Benefits Of Anti-Fatigue Eyeglass Lenses
The reading zone boost and continuous, seamless design of anti-fatigue lenses offer wearers several important functional and aesthetic benefits:
- Anti-Fatigue lenses minimize the eye strain, blurry vision, and the dry eye symptoms encountered during screen-heavy or extended multitasking days.
- bifocals, resulting in a seamless, modern look. Like progressive lenses, anti-tatigue lenses are lack the lined focal zones of
- The small area of added power at the bottom of the lens that gives your vision a slight magnification to help relax your eye muscles and make focusing easier.
- Anti-fatigue lenses reduce the demand placed on eye muscles to contract and maintain focus to read a varous focul length, which in turn results in fewer headaches.
Specialty Eye Glass Lenses.
Anti-Fatigue Lenses Need To Be Professionally Measured
Despite what online sellers may suggest, crafting anti-fatigue lenses that provide clear, high-definition vision requires numerous precise measurements. These measurements include pupillary distances for both near and far focal lengths, optical center, heights, vertex (i.e., the distance between the eye and the back of the lens), pantoscopic tilt (i.e., the angle of the lens from vertical), and wrap angle (i.e., the angle at which the lenses curve around the head). These measurements are specific to each individual's combination of biology, behavioral preferences, frame type, frame fit, and prescription. Modern digital tools should be utilized to obtain the most accurate measurements, and the selected frame must be properly fitted and professionally adjusted to ensure that measurements are precise and customized to the individual.Schedule V-eye-P Eyewear Fitting

Reading Experiences in the Kindergarten Classroom
Kindergarten classrooms also differ in terms of the instructional practices that teachers use to help children learn to read.6 Teachers' practices vary in terms of their instructional approaches—that is, the extent to which learning is teacher directed and involves the whole class; teacher directed and involves small group activities; or teacher guided and involves individual-child activities or child-selected activities. Teachers' practices can also vary according to the ways that children are grouped for instruction—whether children are organized into mixed-level groups, achievement groups, or peer-tutored groups.
In whole-class, teacher-directed activities, the teacher initiates and leads the majority of activities while the entire class is involved. Teachers can also lead and structure small-group and individual teacher-directed activities, which sometimes can occur concurrently with child-selected activities. Child-selected activities in kindergarten might include, for example, the use of learning centers in which the children can choose an activity (and perhaps the time spent on that activity). To account for the difference in the length of day between fulland half-day programs, in this analysis, the minutes that kindergarten teachers reported spending on these activities were converted into the percentage of class time.
Based on teacher reports, fulland half-day classes spent more time in whole class activities than in small group, individual, and child-directed activities. No differences were detected in the percentage of total class time spent on each type of teacher-directed activity by kindergarten program type (figure 5).
In some classrooms, teachers group children for instruction by their level of ability. As mentioned previously, teachers use various types of groups—mixed-level, reading achievement level, and peer-tutoring—to teach reading. Mixed-level groups consist of children of different ability levels working together. Reading achievement groups include children with similar abilities working together. Peer-tutoring allows proficient students to assist those who are less proficient with a learning activity. Ability grouping in kindergarten is related to the type of program. In spring 1999, full-day classes were more likely than half-day classes to use mixed-level groups (48 vs. 42 percent), reading achievement groups (26 vs. 14 percent), and peer-tutoring in reading (23 vs. 15 percent) on a daily basis (figure 6). Half-day classes used mixed-level groups more often than other types of groups (Walston and West 2004).
6The findings about children's reading achievement in the preceding sections reflect percentages of children. The findings in this section refer to percentages of classrooms. Eighty-five percent of kindergartners were in public school classrooms in fall 1998, and the majority of ECLS–K analyses of kindergarten classrooms to date are limited to public schools (Walston and West 2004).

Background: Although bone repair is a relatively efficient process, a significant portion of patients fail to heal their fractures. Because adequate blood supply is essential to osteogenesis, the authors hypothesize that augmenting neovascularization by increasing the number of circulating progenitor cells will improve bony healing.
Methods: Bilateral full-thickness defects were created in the parietal bones of C57 wild-type mice. Intraperitoneal AMD3100 (n = 33) or sterile saline (n = 33) was administered daily beginning on postoperative day 3 and continuing through day 18. Circulating progenitor cell number was quantified by fluorescence-activated cell sorting. Bone regeneration was assessed with micro–computed tomography. Immunofluorescent CD31 and osteocalcin staining was performed to assess for vascularity and osteoblast density.
Results: AMD3100 treatment increased circulating progenitor cell levels and significantly improved bone regeneration. Calvarial defects of AMD3100-treated mice demonstrated increased vascularity and osteoblast density.
Conclusions: Improved bone regeneration in this model was associated with elevated circulating progenitor cell number and subsequently improved neovascularization and osteogenesis. These findings highlight the importance of circulating progenitor cells in bone healing and may provide a novel therapy for bone regeneration.

Cloud Native Solution for 5G Core
Updated: Nov 1, 2019
Venkatesh (Venky) Aravamudhan
This post intends to highlight how cloud native concepts are perceived by telecom operators, their assessment/concerns and as well guidelines for software vendors. Why all this fuzz about cloud native architecture all of a sudden ? 3GPP introduced 5G standards wherein signaling interfaces (core) are all HTTP/2 based and this augurs well for a cloud based solution.
Traditionally, telecom products were based on proprietary hardware and software until few years back when virtualized solution took a front seat enabling COTS hardware to be used for most software components. However, so called real benefits of virtualized environment remain a stretch goal, with ETSI, OSM, ONAP & other frameworks still enhancing their capabilities. Latest industry trends indicate "5G" and "Cloud Native" are the most popular buzzwords used. Operators architecture & planning teams are working on deploying 5G radio (NR) in their current networks followed by core network shortly.
What is Cloud Native ?
In simple terms for a telecom operator, cloud native provides a mechanisms for all network functions & functional modules to be managed and operated in a common way.
Cloud native principles are based on the basic principles listed below
ecomposition of software into multiple micro-service/(s) and run on containers (Read as no monolithic software)
 1. Independent LCM for micro-services
 2. Micro-Services are ephemeral (data layer shall be separate and cannot be part of connectivity or business layer)
 3. Every activity is a code, i.e., every change, features are all software driven
 4. No Manual configuration at all
 5. Employ Continuous Integration (CI) and Continuous Deployment (CD) processes which allows for rapid development, testing, building and releasing software
 6. DevOps support - Utilize common tools at development, test and for operations to ensure better alignment across teams thereby faster fixing of bugs
 7. All events are sent as data streams (Logs, metrics, tracing data are sent as streams for collection, storage and visualizing)
The micro-service architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.
— Martin Fowler

Telecom Operator perspective
In the current environment, most telecom operators have invested heavily on the virtualized solution albeit with mild support for NFV use cases. It has to be noted that virtualized solution solves the problems of not allowing proprietary hardware into their networks.
5G core software suppliers have filled the operators to think and research on cloud native solution. Operators are thinking, researching and evaluating if cloud native provides the necessary uplift to the existing networks. It has to be said, some operators are upbeat and others are in "wait and watch mode". From the operator perspective, following concerns and questions linger
 1. Open Source tools are used in most cloud native environment (thanks to CNCF !), support for these tools and fixes are dependent on open source projects
 2. With heavy investment done in virtualized environment, re-usability of the same
 3. Inter-working between Container environment and virtualized environment for LCM, manageability and operations
 4. In a multiple vendor scenario, NFs may have been developed with different tool sets hence running multiple cloud native environment is a potential option and is it a trouble ?
 5. Continuous Deployment is still far away from being a reality near term
 6. Should operators create their own IaaS and PaaS ?
 7. Up skill of existing workforce to be in-line with this cloud native approach
 8. Faesibility of running 4G network nodes along with 5G nodes, inter-working may be an option to understand
 9. Identifying which vendors provide "Cloud Native" solution and not a mere "Cloud Washing" solution
 10. Compliance of Cloud Security is a topic of IT hence company wide policies may include stringent rules that need to be adhered
 11. Clear migration strategy without compromising cloud native principles
Cloud washing (also spelled cloudwashing) is the purposeful and sometimes deceptive attempt by a vendor to rebrand an old product or service by associating the buzzword "cloud" with it.
- Rouse, Margaret, "cloud washing", in SearchCloudStorage
Cloud Network Function provider takeaway
Network Function software providers need to be wary of the fact that operators have not reaped much benefits from the virtualized solution, hence there is a tendency to brand, cloud native as a marketing gimmick, to sell software. Mobile vendors need solutions to ensure operators confidence is gained by employing some of these concepts
 1. Avoid "Cloud Washing" solution and follow cloud native principles to build software — don't provide operators with the same problem as existing virtualized solution
 2. Create real cloud native solution with micro service(s) to be run top of container and managed by container orchestration environment
 3. Data layer clearly segregated form business and connectivity layer Support containers running micro-services to be supported atop virtualized and as well bare metal infrastructure
 4. Utilize open source tools that are adaptable & utilize Open APIs that can be used across customer PaaS
 5. Ensure best practices on naming conventions, API versioning to enable cleaner solution
 6. Clear strategy for supporting Open Source tools to maintain operator SLAs
 7. Automate testing framework and run Continuous Integration (CI) process within your development to include securities scans (malware, dependencies, vulnerability checks…etc.)
 8. Consistently evaluate security and vulnerability checks in every Agile sprint or couple of sprints at the max
 9. Compliance with CIS benchmarks, NSA, NIST, GDPR and 3GPP security guidelines consistently will help customer with additional confidence
 10. Build Continuous Deployment pipeline in your labs and show case the same as an example to operators to build confidence
 11. Additional help to build Continuous Deployment pipeline at an operator environment may be an additional incentive
 12. Follow frameworks such as Agile to develop software to ensure faster
 13. Mechanisms to integrate with existing operations and serviceability tools (e.g. SNMP trap receiver, log aggregator) will be a biggest add-on (Operator's operations team will support your solution)
It is expected that cloud native adoption is a matter of time, from an operator standpoint, to support 5G use cases. Comparisons with already existing virtualized or bare metal solution during the initial phase are inevitable but this will gradually decrease with increasing cloud native deployments.
Summary
Cloud native solution for 5G generation mobile core provides benefits such as automated mechanisms for delivery of builds, automated upgrades, life cycle management…etc. This may be the first step forward, in creating networks, which are self-learning and adapting.

text: Millimeter wavelength radio telescopes require a high surface and pointing precision, which in steerable open-air telescopes is obtained by a stiff or homologous construction and elaborate thermal control. The perturbing thermal loads and wind loads can also be reduced by protecting the telescope by a radome or astrodome, as applied on several operating telescopes. However, for the new generation telescopes of 30-m to 50-m diameter the radome or astrodome is very large and costly, and it is a priori not certain to which extent the internal thermal climate must be controlled, for instance, by forced air-conditioned ventilation, to obtain a telescope of good radio performance. We present data from the Onsala and Haystack radomes to illustrate agreement between measurements and thermal model calculations, and we use similar calculations to investigate the thermal behavior of a very large astrodome and radome. The accuracy of the calculations is sufficient for design and operational purposes.

The Turkish Get Up (TGU) is a full-body, three-dimensional exercise that is great for shoulder stability, muscle endurance, and grip strength. As we perform this unique and artistic-like movement, there are a variety of high demand positions that our body must meet with the utmost quality in order to perform it successfully and safely. This includes excellent mobility in various aspects of the body, stability, strength, coordination, and mental focus. What is important to understand is that just because the Turkish is get up is a great exercise for may different aspects of movement, that does NOT mean everyone can or should be able to do it instantaneously without specific, individualized practice! In this article, you will learn everything you need to know to not screw up the Turkish Get Up.

Unification - Artificial intelligence:
We have said that the laws of inference for propositional logic detailed in the previous lecture can also be used in first-order logic. However, we have to clear that a little. One important distinction between propositional and first-order logic is that the latter has predicates with expressions as arguments. So, one explanation we have to form is that we may use the inference lawsas long as the predicates and Arguments match up. That's why, not only do we have to check for the right kinds of sentence before we may carry out a law of inference, we also need to check that the arguments do not prohibit the inference.
For instance, let it in our knowledge base, we have the these two statements:
Knows (john) -> hates(john, X)
Knows(john, marry)
and we need to use the Modus Ponens law to infer something latest. In this case, there is no difficulty, and we may infer that, because john hates everybody he knows, and he knows Mary, then he should hate Mary, i.e., we may infer that hates(john, mary) is right.
However, let it instead that we had these two sentences:
knows(john,X) -> hates(john, X)
knows(jack, mary)
Here, the predicate names have not altered, but the arguments are handling us back from forming any deductive inference. In the first case above, we might allow the variable X to be instantiated to marry during the assumption, and the constant john before and after the assumption also matched without error. However, in the second case, although we might still instantiate X to marry, we could no longer match john and jack, because they are two dissimilar constants. So we cannot deduce anything for john (or anyone else) from the latter two statements.
The problem here arises from our incapability to make the arguments in knows(john, X) and the arguments in knows(jack, marry) match up. When we may make two predicates match up, we say that we have combined them, and we will look at an algorithm for unifying two predicates (if they can be combined) in this section. Remember that unification acts a part in the way Prolog searches for matches to queries.

In a study led by UCSF team an existence of relationship between asthma and composition of bacterial species, which are present in bronchial airways was revealed.
This finding could suggest new treatment or even potential cures for the common inflammatory disease.
Using new detection methods, researchers learned that the diversity of microbes inside the respiratory tract is far vaster than previously suspected - creating a complex and inter-connected microbial neighborhood that appears to be associated with asthma, and akin to what has also been found in inflammatory bowel disease, vaginitis, periodontitis, and possibly even obesity.
"People thought that asthma was caused by inhalation of allergens but this study shows that it may be more complicated than that - asthma may involve colonization of the airways by multiple bacteria," said study co-author Homer Boushey, MD, a UCSF professor of medicine in the division of Pulmonary and Critical Care Medicine.
In their three-year pilot project, the scientists collected samples from the airway linings of 65 adults with mild to moderate asthma and 10 healthy subjects. Then, using a tool that can identify approximately 8,500 distinct groups of bacteria in a single assay, the scientists profiled the organisms present in each sample to look for relationships between bacterial community composition and clinical characteristics of the patients' asthma.The researchers found that bronchial airway samples from asthmatic patients contained far more bacteria than samples from healthy patients. The scientists also found greater bacterial diversity in the asthmatic patients who had the most hyper-responsive or sensitive airways (a feature of asthma).
The study has been published online in the Journal of Allergy and Clinical Immunology.

CHRISTIANS & JEWS TO WEAR YELLOW IN IRAN
A new dress-code law reportedly passed in Iran this past week mandates the government to make sure that religious minorities - Christians, Jews and Zoroastrians - will have to adopt distinct colour schemes to make them identifiable in public, the Canadian National Post reported on Friday.
Melanie Phillips points out that this is not the first time that such a demand was made by a Muslim country.
But what many may not realise is that the yellow star by which the Jews in Nazi Germany were branded has wider and deeper origins. Indeed, it started under Islam, when Jews living under Muslim rule in the eighth and ninth centuries were forced to wear first a distinguishing mark and then a piece of yellow cloth, variously a belt, a turban and a badge. This sign of 'dhimmi' status was subsequently adopted in medieval times in Europe and in Britain, where Jews were forced to wear a yellow badge.
The Nazi yellow star was merely the latest reworking of that historic global obscenity. Until now.
The story may be doubtful. Lots of updates to be found on hot air
An Iranian Armenian adds:
When I was in Iran 5 years ago, all Armenian (or non-Muslim) shops had to post a sign saying that they are Christian to warn Muslims buying food from them. Armenian were not allowed to teach Armenian language in Armenian schools during the official schools hours. Armenian was taught after hours....Also, Armenians are not allowed to hold any government jobs...so , no wonder Armenian population in Iran has decreased from 200,000 to as low as 50,000.....

Jumping is used in many sports for different purposes. In each sport, the jump is performed in a way that enhances the purpose of the jump, such as:
- High jumpers perform a backward roll over the bar, to gain the greatest height (which works because they have a cushioned landing area).
- Long jumpers extend their arms legs in front of their body, to reach out and gain the greatest distance (which works because they have a cushioned landing area).
- Hurdlers use an extended scissor action of the legs to clear the hurdle, gain height, and set themselves up for the next hurdle (which works because they know what is on the other side of each hurdle).
No matter the sport, the primary purpose of a jump is to raise the body to higher altitude (except with jump off or into something, such as jumping off a diving board or parachuting from an aircraft, where the purpose is to lose altitude). A secondary purpose may be to move the body quickly over a distance, such as jumping out the way of a foil in fencing. Martial arts jumps share these purposes but they have two important variables to deal with—an opponent that wants to harm them and unfamiliar terrain. This means that during a martial arts jump, the jumper must remain stable, be able to defend him or herself during the jump, be prepared for an unknown landing areas, and land in way that permits further offensive or defensive actions if needed.

The data presented in this paper establish the finding that multiple specific protective antibodies exist in rabbits in response to immunization with Group B streptococci. The summary in Table I indicates the serological types into which Group B streptococci have been divided on the basis of their antigenic composition. This classification is dependent upon passive protection of mice with antibodies directed against the specific antigens, and types are defined in these terms. Heretofore, it was thought that type-specific polysaccharides accounted for all such protection in Group B streptococci. Certain exceptions of cross-protection between types due to minor polysaccharide determinants soon appeared; cross-protection reactions based on protein determinants in at least two types were also discovered. The present experiments show that specific antibodies directed to either polysaccharide or protein antigens of a single strain can be protective against infection with streptococci containing these antigens.

The Four Ways Unstructured Data Can Improve Your Business
Dig unstructured sources for data that reveals valuable insights into customer transaction behaviors
With changing behaviors and buying preferences, it can be a challenge for distributors and manufacturers to fully grasp a complete understanding of customer needs. As discussed in a previous post, decision makers often rely on easily accessible digital channels such as e-commerce or punch-out for customer transaction insights. Extracting information solely from those sources however, does not provide a complete picture of customer transactions. They might be overlooking a great deal of other valuable insights. Unstructured data that remains in unorganized and hard to access formats such as e-mail orders can provide new actionable business intelligence.
Deploying Sales Order Analytics to extract and map unstructured data helps easily derive and manage information from emailed orders. With an in-depth look into customer transaction trends, decision makers have the opportunity to access data points that might have previously been missed. Tapping into unstructured data from email orders helps reveal new patterns and trends. Distributors and manufacturers can then gain a better understanding of which sales and customer service processes may require improvements and base strategic decisions on more accurate and complete insights.
Four hidden opportunities that can be uncovered from emailed orders:
 - Timing Patterns: Understanding when purchase orders typically get placed during the day allows distributors and manufacturers to allocate staff accordingly. This information can also help to time discount offers or promotions to target customers during peak times, increasing opportunities to up-sell and cross-sell.
 - Order Volume: Additional insight into periods of high/low order volumes help distributors and manufacturers manage inventory. This is because they now have a more accurate sense of the time and volume of products customers need during a given period. Understanding when orders are placed as well as the quantity of orders enables distributors to ensure inventory is appropriately stocked and guarantees order fulfillment.
 - High-Traffic Channels: With data from all sales channels including but not limited to e-mails, decision makers can identify the channel with the highest customer traffic. They can then adjust operational requirements and introduce digital solutions as needed to increase efficiency. For example, if e-commerce is the most used platform, consider document automation to process orders placed online into existing ERP systems.
 - Buyer Habits: Core to growth is understanding and responding to customer needs. Therefore, information on customer transaction preferences and buying habits are essential to profitability and productivity. A comprehensive snapshot of customer transactions enabled by data from all sales channels ultimately creates a more competitive business. Customer profiles created using this data can be used by sales reps to deliver targeted sales messages and personalized service.
There is a substantial amount of usable data sitting in unstructured sources like emailed orders. In today's challenging marketplace, smart distributors and manufacturers must consider new ways to maintain a competitive edge. Digging into untapped data sources can lead to more advantages and opportunities to better serve customers.

- 6 b&w illustrations
This beguiling book asks a set of unusual and fascinating questions - why is early Chinese printing so little acknowledged, despite anticipating Gutenberg by centuries? Why are the religious elements of all early printing overlooked? And why did printing in China not have the immediate obvious impact it did in Europe?T. H. Barrett, a leading scholar of medieval China, brings us the answers through the intriguing story of Empress Wu (AD 625-705) and the revolution in printing that occurred during her rule. Linking Asian and European history with substantial new research into Chinese sources, Barrett identifies methods of transmitting texts before printing and explains the historical context of seventh-century China. He explores the dynastic reasons behind Empress Wu's specific interest in printing and the motivating role of her private religious beliefs. He also deduces from eighthand ninth-century Chinese records an explanation for the lesser impact of the introduction of printing in China than in Europe. As Renaissance Europe was later astonished to learn of China's achievement, so today's reader will be fascinated by this engaging perspective on the history of printing and the technological superiority of Empress Wu's China.
T. H. Barrett is professor of East Asian History at the School of Oriental and African Studies, London. Among his books are Taoism Under the T'ang; Li Ao: Buddhist, Taoist or Neo-Confucian? and, with Peter Hobson, Poems of Hanshan. He lives in Cambridgeshire, England.
'... fascinating and makes us gasp at the early Chinese civilisation for both their progressive thinking and their cruelty. We in the West need to look with fresh eyes at the world social history and thankfully Yale University Press is at the forefront of this.' Bill Spence, Yorkshire Gazette and Herald
'The real thrust of his [Barrett's] beautifully compact but formidably well-researched book lies in its thoughtful investigation of Wu and her milieu. Indeed so literate is The Woman Who Discovered Printing that it belongs immediatley to that fine tradition of English writing about Chinese initiated by Arthur Waley.' Justin Wintle, The Independent

On Wednesday, the minister of education Costas Kadis announced that the public universities of Cyprus will be allowed to found businesses or organisations, or enter partnerships, aiming to exploit discoveries or inventions from their scientific research.
Kadis said the body approved the legislative framework that will allow turning the results of scientific research, innovation, and scientific knowledge of public universities, to commercial products and services that will benefit not only the universities, but the economy and society as a whole.
According to the minister, this will make our public universities even more modern and bring them closer to the economy's productive fabric. Meanwhile, it will create new jobs and boost the economy. In reality, Cyprus is following the example of countries that have achieved progress from such policies. It should be noted that Israel's leaps in the field of knowledge society have been based on such partnerships.
It should be also noted that the cabinet also approved a government bill banning smoking in schoolyards. Kadis said that this is a law that must be adhered to by everyone, and what it stipulates in all instances will apply to our schools. We have adapted to European norms and directives, and we will try to implement this legislation in collaboration with other ministries.

Hon'ble Minister for Women and Child Development, Smt Maneka Sanjay Gandhi laid a foundation of Sakhi Suraksha Advanced DNA Forensic Laboratory in the campus of Central Forensic Science Lab, Chandigarh today. Speaking at the event, the Minister said that forensic analysis plays a critical role in criminal investigation and the Advanced Lab will contribute to addressing the gap in forensic DNA analysis of pending sexual assault cases in the country. The Minister added that the lab is being set up as a model forensic lab and would be replicated in other parts of the country.
In sexual assault cases, the ideal time frame to complete the examination and submission of the report is 90 days. Furthermore, it is important that the biological crime exhibit is stored and preserved in a scientific manner so as to make any examination/reporting meaningful. However, presently such a storage/preservation capacity is around 200 cases in CFSL, Chandigarh.
Sexual Assault and Homicide Unit
Paternity Unit

Honoring ancient petroglyphs in Utah to be mammoth event
Courtesy of Andrew Gulliford
Fort Lewis College Professor Andrew Gulliford, who wrote earlier this year about the discovery of mammoth petroglyphs near Bluff, Utah, is tickled by the creative offering some residents of the town are making to the ancient rock art.
On Dec. 21 - the winter solstice - they will burn a 16-foot-tall mammoth effigy.
"Who needs to go to Nevada for the Burning Man Festival when you can go to Bluff and burn a mammoth?" Gulliford wrote in an email with a photo of the mammoth attached.
Joe Pachak, a rock expert and local artist who was the first to discover the petroglyph, said the idea of the burning is to draw attention to the petroglyphs.
"This will promote more recording by scientists of rock art in the future," he said.
The petroglyphs, first of discovered in 1987, have long been a subject of controversy.
Scientists question whether these illustrations really depict mammoths, and many residents of the town have advocated for further protection of the site where they were discovered.
Since the first discovery, more possible mammoth petroglyphs have been discovered.
Gulliford, in his Durango Herald and Cortez Journal column "Gulliford's Travels," also argued for further protection by the Bureau of Land Management.
The wooden mammoth was built over a three-week period by Pachak and local Bluff residents using only sticks and two support poles. It is built to the scale of an actual mammoth.
Pachak said many volunteers helped with the making of the mammoth, with a group doing the design and about 30 others assisting in construction on a volunteer basis. The sculpture has been on display for a week.
Gulliford is a frequent visitor to Bluff.
"What really appealed to me is the size of the mammoth - it's to scale," he said. "Mammoths are smaller than mastodons, and I didn't know that."
Gulliford plans to go to Bluff for the burning.
The mammoth will be burned at 8 p.m. in a ceremony complete with drumming and flaming darts to set the structure on fire.
Pachak said residents of Bluff are excited about the petroglyphs, which, at about 13,000 years old, may be some of the oldest rock art in North America.
In March, a group of 30 volunteers led by resident Anne Phillips recorded the fourth mammoth petroglyph.
Pachak hopes to see these practices continue because it could lead to more discoveries in the future.
"That's why it's very important to record the rock art - the other elements were discovered by documenting very well," he said.


Door Alarms for Wandering in Dementia
Door Alarms Can Help Alert You if a Loved One with Dementia Is Going Outside
SilviaJansen/ Getty Images
If your loved one or patient with Alzheimer's disease or a different type of dementia wanders and attempts to leave your home or facility, one option to increase their safety is to place alarms on the doors. You can also try different locking mechanisms such as a latch up high, but the concern with that strategy is that in case of a fire, the person may not be able to escape safely out of the house.
An alarm can allow the person to attempt exiting through the door but will also alert you to her need for assistance. Alarms can offer you a little support and reassurance in your efforts to ensure your loved one's safety so that, rather than feel that you have to constantly check on her, you know that the alarm will sound if she suddenly wakes and needs assistance.
Uses for Door Alarms
 - Protect Individuals from Elopement and Wandering
 Whether intentionally attempting to "run away" or simply wandering around and locating a door, those at risk for exiting without the needed supervision may benefit from a door alarm on the exterior doors.
 - Alerts Others for Assistance
 Door alarms can also be used on the bathroom door. They can be placed in such a way that they'll sound when the door is opened, letting you know that your loved one or patient requires assistance in the bathroom.
Types of Door Alarms
 - String Alarm
 A string alarm can be placed high up on the door frame with the string placed across the door opening. If the door opens, it will cause the string, which is held in place by a magnet, to detach from the alarm, causing it to sound. The alarm will stop sounding once the magnet is reattached.
 - Passive InfraRed (PIR) Alarms
 A PIR alarm can be utilized across a door opening so that if the plane across the door is broken, the alarm will sound and alert you to your loved one's need for assistance.
 - Magnetic Door Alarms
 Magnetic door alarms have two parts that are connected magnetically. One part is attached to the door frame right at the edge next to the door and the other part is attached to the door right next to the frame. The alarm sounds when the two parts are no longer connected by the magnet.
 - Floor Sensor Alarms
 Floor sensor alarms have a sensor pad on the floor and a magnetic lock on the door. They can be preset to different settings, some of which will alarm immediately and other settings that allow a person to exit out the door and return just a short time later before sounding.
Another option if you have doors in your house that you don't want your loved one to open, you can simply lock them or have a keypad lock installed on those doors. The keypad locks will unlock once you enter the correct number code in the keypad. Keypad locks can connected be to the smoke or fire alarm system so that they will unlock in case of a fire.

text: Species formed during the decomposition of silane-methane-hydrogen mixtures ([SiH4]x:[CH4]y:[H2]z), by spatial plasma separation technique using the TCDDC (Two Consecutive Decomposition and Deposition Chambre) systeml, are evaluated by mass spectrometric analysis and related with the structural and electro-optical properties for either amorphous (a-) or microcrystalline (μc-) thin films. Results obtained show that in the plasma region, the main reaction is the direct fragmentation of SiH4 by electron impact whilst near the growing surface, the main detected species are excited. The kind of species and their intensity depend strongly on the power density (dp), mixture gas ratio (g = CH4 /SiH4+CH4), static electromagnetic (ξ, B) fields and r.f. frequency (f), used. Since CH4 has a threshold decomposition higher than that one of SiH4, the species presented at the plasma region are, mainly, methyl, dimethyl and CH2-CH2 graphitic-like chains depending, mostly, on dp and on g. By diluting the mixture in H2, we observe the existence of active H2 species that, for high dp, may lead to a transition from the amorphous to microcrystalline phase, as well as a carbon incorporation in the amorphous tissue as graphitic-like bonds. This allow us to infer the merit of the TCDDC system in producing a-/μc-thin films that can be applied to photovoltaic and other applications.

Capture Silky Smooth Moving Water
Water is a compelling photographic subject. And how you capture it makes an impression on the viewer. Freezing the action for crystal clear water droplets from a crashing wave or pool splashes conveys power and energy. Slowing the motion down to create a milky white stream of water creates a more serene picture.
In this photo taken on the Little Falls Trail in Promised Land State Park, Poconos, PA, I hiked in mid-morning with my 18-400mm all-in-one lens as well as an electronics cable release designed for your camera and my travel tripod, two must-have accessories to create silky water fall action. Getting as close down and into the flowing water as possible creates a more dramatic perspective.
Settings are very important. First, set your camera to aperture priority and choose an aperture that will give you deep depth of field (between F11-F22 is ideal) so that your foreground to background will be in focus. I used F11 here. Next, select ISO 100. Now look thru the viewfinder and see if your shutter speed is below 1/15th second (I shot my image above at 1/6th second). You can change your aperture to make the shutter speed faster or slower. If you move the aperture from F11 to F16, the shutter speed be slower. If you open up your aperture to F8 to let light more light in, the shutter speed will be faster. Start shooting to see your effect and change your aperture until the image looks the way you want it to.
Since you will be shooting at slow shutter speeds below 1/60th second, you will not be able to handhold the camera. You must use a sturdy tripod and a cable release to ensure there is no camera shake.
The three settings involved in creating an image of a waterfall are referred to as the exposure triangle. The ISO, the aperture and the shutter speed all work in concert to create the effect. So your constant will be your ISO. The second that you will work with is your aperture. Opening or closing the aperture will change the shutter speed to be faster or slower. The shutter speed is ultimately the setting that will either freeze the water (faster shutter speed) or create the silky effect (slower shutter speed).
And the last tip for any landscape photo is to focus about a third of the way into the scene. This will give you the best results for foreground to background focus.
This tip is a good self-assignment for any season. So, find a park with waterfalls within driving distance and head out with your wide-angle lens, tripod and cable release.

Photographing Pets
One Location. Two Entirely Different Photos.
Change your position_compSometimes we take the shot we had in mind and call it a day. But when the light is so beautiful at sunset, it pays to take a few steps around just to check out how the sun is lighting your subject. The photo on the left was the one I was after: two girls watching the sunset, captured in near silhouette as the center-weighted meter gave an exposure for the bright setting sun and made most of the other parts of the shot go dark. Just what I wanted. But then I sat down next to the girls to watch the sunset with them, and wow, was the light across their faces gorgeous. So of course I snapped away while the sun set! Because the light was low, I boosted my ISO to 640 and got a shutter speed of 1/100th sec at F/5.0 aperture. If I had unlimited cooperation from my two subjects, I would have boosted the ISO to 1000 and shot more photos at F/8 so that the girl further back would be in sharper focus. When shooting more than one person, either try to get them on the same plane of focus, or deepen your depth of field by using a smaller aperture like F/8. Not always possible, as was the case here, but the sweet expressions and the light make the shot a perfect one for me.
Free Photo Tips Card Download 1: Aperture
TIPS CARDS_final.psd
I'm using my time in the airport in Palm Springs (I'm painfully early for my flight and it's 112 degrees outside so I can't even enjoy the outside cafeteria) to finish and upload the first of what I hope will be many free download cards. These will be a series of cards that you can print out and keep with you to refer to when you're out shooting. The first is about aperture priority mode. I've covered this topic a lot since I feel it is the most important technique to master to make better photos. Understanding what is does allows you to be more creative since you can force the outcome of your image to better tell your story. And we all know practice is the best way to master any technique. So print out this first set of cards on one letter-size sheet of photo paper (luster is best since it won't scratch as much). Then cut the paper along the grey lines to give you a set of four cards. If you like, punch a whole in the corners and put them on a D-ring key chain and attach them to your camera bag. You could even have them laminated at your local office supply store. This is the first set of Chasing Picture Perfection Tips Cards. Download the file at this link
Unclutter Your Photo's Background
Understanding the function of F-stops, or the aperture of your lens, is undeniably the most confusing of your DSLR's features. However, once you master it, you will make a huge leap forward in the quality of your photos.
As a photo student in high school and college, I stuck a slip of paper onto the back of my camera (yes, in film days SLRs had a bookplate slot on the back of the camera where you slipped in a flap from your film box so that you could remember what film you had loaded. Can you imagine?!). On this slip I wrote, "open aperture=blurry" and "small aperture=sharp."
An open aperture lets in a lot of light. On your lens it is a setting like F/2.8, 3.5, 5.6, or 6.3. Think of the aperture as your eye's pupil. If there is not much light, your pupil gets bigger, or "opens" to let in more light. But a big result of using an open aperture is the effect of a blurry background that really makes your subject pop off the page (or screen). You can easily control the aperture setting on your camera by putting the camera on "A" and dialing in one of the aforementioned numbers. Your camera will automatically pick a shutter speed to make a proper exposure.
If you have a distracting background, dialing in a wider (or open aperture) will make the background blurry and eliminate the distractions. However, maybe you want the background really clear. Like if you're standing in front of a sign that you want to be able to read in the photo. Then you would dial in a small aperture.
In this first photo, her eye is in focus, but her earring is not, and neither is the tip of her nose. I was just a few feet away and had the camera set to "A" (Aperture Priority) and dialed in F/6.3. Now conversely, if you choose a small aperture, like F/22 or F/32, your background will appear more sharp. Again, imagine a bright sunny day and how your pupils react: they get smaller and let in less light. But also, think about when you squint and how things get clearer. This is sort of how a smaller aperture works. In the second photo, I dialed in F/32 and her earring is now in more focus.


text: Cooperative diversity techniques have been proposed to improve the performance of modern wireless mesh networks. The increased demand for bandwidth has led to the employment of frequencies above 10 GHz, where the dominant fading mechanism is rain attenuation. The rain attenuation induced on a microwave path is usually modelled as a lognormal random variable. In this paper, the outage performance analysis of a cooperative diversity system operating at frequencies above 10 GHz is presented, employing spatially correlated lognormal fading channels. The final destination node combines the direct link signal with a signal received through a regenerative (decode-and-forward) relay using selection combining. Various multiple-access protocols are considered, while energy and spectral efficiency are investigated. Extended numerical results present the impact of various operational, geometrical and geographical on the system performance. Finally, comparison with an effective direct link highlights the gain of cooperative diversity techniques.

Excerpts from this Manual
MySQL 5.6 Reference Manual / ... / KEY Partitioning
19.2.5 KEY Partitioning
Partitioning by key is similar to partitioning by hash, except that where hash partitioning employs a user-defined expression, the hashing function for key partitioning is supplied by the MySQL server. NDB Cluster uses MD5() for this purpose; for tables using other storage engines, the server employs its own internal hashing function which is based on the same algorithm as PASSWORD().
The syntax rules for CREATE TABLE ... PARTITION BY KEY are similar to those for creating a table that is partitioned by hash. The major differences are listed here:
 - KEY is used rather than HASH.
 - KEY takes only a list of zero or more column names. Any columns used as the partitioning key must comprise part or all of the table's primary key, if the table has one. Where no column name is specified as the partitioning key, the table's primary key is used, if there is one. For example, the following CREATE TABLE statement is valid in MySQL 5.6:
 CREATE TABLE k1 (
 id INT NOT NULL PRIMARY KEY,
 name VARCHAR(20)
 )
 PARTITION BY KEY()
 PARTITIONS 2;
 If there is no primary key but there is a unique key, then the unique key is used for the partitioning key:
 CREATE TABLE k1 (
 id INT NOT NULL,
 name VARCHAR(20),
 UNIQUE KEY (id)
 )
 PARTITION BY KEY()
 PARTITIONS 2;
 However, if the unique key column were not defined as NOT NULL, then the previous statement would fail.
 In both of these cases, the partitioning key is the id column, even though it is not shown in the output of SHOW CREATE TABLE or in the PARTITION_EXPRESSION column of the INFORMATION_SCHEMA.PARTITIONS table.
 Unlike the case with other partitioning types, columns used for partitioning by KEY are not restricted to integer or NULL values. For example, the following CREATE TABLE statement is valid:
 CREATE TABLE tm1 (
 s1 CHAR(32) PRIMARY KEY
 )
 PARTITION BY KEY(s1)
 PARTITIONS 10;
 The preceding statement would not be valid, were a different partitioning type to be specified. (In this case, simply using PARTITION BY KEY() would also be valid and have the same effect as PARTITION BY KEY(s1), since s1 is the table's primary key.)
 For additional information about this issue, see Section 19.6, "Restrictions and Limitations on Partitioning".
 Columns with index prefixes are not supported in partitioning keys. This means that CHAR, VARCHAR, BINARY, and VARBINARY columns can be used in a partitioning key, as long as they do not employ prefixes; because a prefix must be specified for BLOB and TEXT columns in index definitions, it is not possible to use columns of these two types in partitioning keys. In MySQL 5.6, columns using prefixes are permitted when creating, altering, or upgrading partitioned tables, even though they are not included in the table's partitioning key. This is a known issue in MySQL 5.6 which is addressed in MySQL 8.0, where this permissive behavior is deprecated, and the server displays appropriate warnings or errors when attempting to use such columns in these cases. See Column index prefixes not supported for key partitioning, for more information and examples.
 Note
 Tables using the NDB storage engine are implicitly partitioned by KEY, using the table's primary key as the partitioning key (as with other MySQL storage engines). In the event that the NDB Cluster table has no explicit primary key, the hidden primary key generated by the NDB storage engine for each NDB Cluster table is used as the partitioning key.
 If you define an explicit partitioning scheme for an NDB table, the table must have an explicit primary key, and any columns used in the partitioning expression must be part of this key. However, if the table uses an empty partitioning expression—that is, PARTITION BY KEY() with no column references—then no explicit primary key is required.
 You can observe this partitioning using the ndb_desc utility (with the -p option).
 Important
 For a key-partitioned table, you cannot execute an ALTER TABLE DROP PRIMARY KEY, as doing so generates the error ERROR 1466 (HY000): Field in list of fields for partition function not found in table. This is not an issue for NDB Cluster tables which are partitioned by KEY; in such cases, the table is reorganized using the hidden primary key as the table's new partitioning key. See Chapter 18, MySQL NDB Cluster 7.3 and NDB Cluster 7.4.
It is also possible to partition a table by linear key. Here is a simple example:
CREATE TABLE tk (
 col1 INT NOT NULL,
 col2 CHAR(5),
 col3 DATE
)
PARTITION BY LINEAR KEY (col1)
PARTITIONS 3;
Using LINEAR has the same effect on KEY partitioning as it does on HASH partitioning, with the partition number being derived using a powers-of-two algorithm rather than modulo arithmetic. See Section 19.2.4.1, "LINEAR HASH Partitioning", for a description of this algorithm and its implications.

Germany passes 50,000 coronavirus deaths as infections decline
Germany's coronavirus death toll on Friday surpassed 50,000 even as the number of new daily infections in the country is dropping.
The Robert Koch Institute, Germany's disease control center, recorded an additional 859 deaths on Friday, bringing the total number of fatalities due to COVID-19 to 50,642, according to The Associated Press.
As of late Friday morning, data compiled by Johns Hopkins University indicated that Germany has now had 51,134 coronavirus deaths, with a total of more than 2.1 million people infected.
While Germany was more successful than other countries at containing the virus in the early months of the pandemic, daily death tolls have reached as high as 1,000 in recent months, hitting a total of 40,000 on Jan. 10.
The AP reported that Lothar Wieler, head of the Robert Koch Institute, said the explanation for the increased number in coronavirus deaths is "relatively simple but relatively depressing."
"The increase is simply linked to the fact that the case numbers went up so much," he added.
Wieler added that there are currently more than 900 coronavirus outbreaks at nursing homes in the country, as well as a larger number of cases among Germans over the age of 80.
German President Frank-Walter Steinmeier announced Friday that he plans on leaving a light in one of his windows at his Bellevue palace in Berlin every evening starting Friday to commemorate the lives lost to COVID-19.
Steinmeier said the lights are a sign that "the dead in the corona pandemic are not just statistics for us."
"Even if we don't know their names and families, we know that every figure stands for a loved one whom we miss infinitely," he added.
Germany began its coronavirus vaccination campaign late last month, beginning with elderly populations and health care workers taking care of vulnerable groups.
However, while German Health Minister Jens Spahn initially had a target of 300,000 inoculations per day for the country, data from the Robert Koch Institute showed a daily average of approximately 86,000 as of Wednesday.
In total, more than 1.3 million people in Germany have been vaccinated since late December.
Stefan H.E. Kaufmann, founding director of the Max Planck Institute for Infection Biology in Berlin, told CNBC Tuesday that Germany has faced multiple challenges in administering the vaccine.
"Number one priority are currently the elderly and people with severe pre-disposing diseases, notably in nursery homes," he explained. "This process is ethically fine, but it is very time consuming."
He added, "it also includes health care workers and medical staff at nursing homes and hospitals. Apparently some of the nursing home staff is hesitant with respect to vaccination."

Lignin-fueled photoelectrochemical platform for light-driven redox biotransformation†
The valorization of lignin has significant potential in producing commodity chemicals and fuels from renewable resources. However, the catalytic degradation of lignin is kinetically challenging and often requires noble metal catalysts to be used under harsh and toxic conditions. Here, we report the bias-free, solar reformation of lignin coupled with redox biotransformation in a tandem structure of a BiVO4 photoanode and perovskite photovoltaic. The tandem structure compensates for the potential gap between lignin oxidation and biocatalytic reduction through artificial Z-schematic absorption. We found that the BiVO4-catalyzed photoelectrochemical oxidation of lignin facilitated the fragmentation of higher molecular weight lignin into smaller carboxylated aliphatic and aromatic acids. Lignin oxidation induced photocurrent generation at the photoanode, which enabled efficient electroenzymatic reactions at the cathode. This study successfully demonstrates the oxidative valorization of lignin as well as biocatalytic reductions (e.g., CO2-to-formate and α-ketoglutarate-to-L-glutamate) in an unbiased biocatalytic PEC platform, which provides a new strategic approach for photo-biocatalysis using naturally abundant renewable resources.

Law Enforcement and Society
Law Enforcement and Society: Lessons of the Holocaust is a one day training run by the Anti-Defamation League (ADL), in partnership with the United States Holocaust Memorial Museum (USHMM), that highlights the core values of American law enforcement and their unique role as protectors of the Constitution and individual rights.
The program was initially created in 1998 at the request of Washington's former Police Chief Charles Ramsey. Since then, more than 60,000 law enforcement professionals have participated in the program. Participating agencies now include the Federal Bureau of Investigation, US Immigration and Customs Enforcement, and Drug Enforcement Administration, among others.
In 2007, ADL received the FBI Director's Community Leadership Award in recognition of LEAS, and the ongoing partnership between the ADL and FBI.

There are a number of different benefits to this process.
- The first helps to reduce the thatch/mat layer of the green. The 37 blades on each of 3 reels will cut through the surface and remove some of the dead plant material. Topdressing sand is applied to the green and the sand takes the place of the dead plant material. This will improve firmness of the greens surface and does provide some gas exchange near the surface of the green.
- Since we had recently aerated our greens and had a great deal of sand near the surface, I did not want to go extremely deep with our operation. Our purpose was to cut through the bentgrass that by its nature grows sideways and will attempt to lay over. The vertical action of the mower cuts through the longer leaf blades.
- The cutting action of the mower will also stand up the leaf blades. The less grass surface that the ball touches, the less friction created and the better ball roll that our greens will have.
We will do a lighter version of this work during the season until the heat of summer kicks in.

Hydrogen offers a route to storing renewable electricity and lowering greenhouse gas emissions. Metal–organic framework (MOF) adsorbents are promising candidates for hydrogen storage, but a deep understanding of their potential for large-scale, stationary back-up power applications has been lacking. Here we utilize techno-economic analysis and process modelling, which leverage molecular simulation and experimental results, to evaluate the future opportunities of MOF-stored hydrogen for back-up power applications and set critical targets for future material development. We show that with carefully designed charging–discharging patterns, MOFs coupled with electrolysers and fuel cells are economically comparable with contemporary incumbent energy-storage technologies in back-up power applications. Future research should target developing MOFs with 15 g kg−1 of recoverable hydrogen adsorbed (excess uptake) and could be manufactured for under US$10 kg−1 to make the on-site storage system a leading option for back-up power applications.

Trimming Buds: Wet Trimming vs Dry Trimming
There is a long and drawn-out process before you will be able to smoke your weed. Trimming is just a single part of it and also one of the most boring things to do with marijuana.
You will be stuck for hours staring at wee, but the trimming is rather important as leaving some of the unwanted leaves and buds on the plant can and will hinder the quality of THC.
Trimming also affects the look, reduces mold formation, and grants smoother smoking.
Trimming is the action you do next after growing the plant. Although it might appear boring, it is rather important and worth your time and effort, due to the ultimate result.
Wet Trimming
Wet trimming is the faster one as it is all done in just one sitting. It can be done as soon as you harvest your flowers. Ultra sticky because of the water that is still in the flower, cut the branch near the node with a pair of curved trimming scissors. Each branch has several buds so try not to detach them until the trimming is near the end. Prepare scissors and a tray and put the gloves on your hands so you will prevent getting resin on your hands.
Now it is the trimming time. Cut away all the sugar leaves on each bud of each branch. Carefully use your curved scissor so you don't damage the flower. Some sugar leaves will prevail but that is normal, as some can be concealed by the body of the bud.
Pros and Cons of Wet Trimming
Wet trimming has several ups and downs.
By doing the wet trim it is much easier to remove sugar and fan leaves since during dry trim they get shriveled and dried up.
Drying is also a lot quicker as less moisture-filled foliage is attached to the flowers.
Wet trimming gives you a more pleasing final look at the plant and buds.
According to sources, wet trim also affects less the quality of the buds as trichomes remain intact, preserving terpenes and flavors of the final product.
Wet trimming is a rather sticky method and you can get trichomes all over your body, fingers, scissors, and everything else.
When starting wet trimming, there is no pause and you will need to cut all your plants down and separate branches and trim them right away.
Drying and Curing
Once you have completed trimming, before smoking it you need to dry and cure your beautiful buds. Put them on a drying rack in a room with ventilation and lightly heated. When they are dry, remove the buds from the individual buds from the branches and leave them in jars for curing.
Dry Trimming
Dry trimming is performed between drying and curing. Harvest your plants and cut them at the base. After this hang them upside down and leave them in a warm room with ventilation. After the drying period, cut off an individual branch and prepare them for trimming. Before trimming, wash your hands and put on a pair of gloves. Take the scissors in your hands and start cutting away all the sugar leaves from each bud. Cut the buds one at a time as this will make it easier for you to cure and store them. Once the trimming is completed load the buds into the curing jars.
Pros and Cons of Dry Trimming
Just like wet trimming, dry trim also has its benefits and drawbacks.
A lot less messy than the wet trimmings since the trichomes are hardened.
As you keep plants hung to dry it slows the express loss of terpenes.
Unfortunately, the less messy trichomes become rather brittle as they dry out and are very prone to breakage. Handle them with care as you don't want the loss of trichomes and THC levels.
Space might be the problem since the entirely hanged plants take much more space than the chopped plants. You should make sure that you have an adequate drying space before you start the dry trimming.
Which is Better: Wet or Dry Trimming?
The most important question is of course whether you should trim the plant wet after it was freshly harvested or after leaving it for a few days to dry.
Several pros and cons are there to weigh on the right choice, and the quality of the weed depends on many factors.
Harvesters have argued on both methods with pros and cons for each one, but have agreed that trimming is one of the most important processes in weed growing. It takes a lot of time, but at the final stage, you are awarded a delicate smell, taste, and feel.
Dry trimming gives you a better aroma but also it takes longer than wet trimming, while the wet trimming is faster, mold formation is dramatically lower in percentage, but the flowers and their extracts are of lower quality, and loss of resin and terpenes is unavoidable.

New sentencing guidelines that will see the courts take full account of the harm caused by offences such as arson attacks on historic buildings or criminal damage leading to severe disruption of public services were published today by the Sentencing Council.
For the first time, all courts in England and Wales will have formal guidance to ensure that they take account of:
- The full impact of arson or criminal damage such as vandalism on national heritage assets including listed buildings, historic objects or unique parts of national heritage and history.
- The economic or social impact of damaging public amenities and services such as a fire at a school or community centre, or criminal damage at a train station, which can adversely affect local communities or cause economic hardship to neighbouring houses or businesses.
- The effect on communities when an area's emergency services or resources are diverted to deal with an incident of criminal activity.
The guidelines acknowledge that harm can involve not only physical injury but long-term psychological effects, and that damage to property can be about more than just its financial value.
Judges and magistrates will also consider requesting reports to ascertain both whether the offence is linked to a mental disorder or learning disability in order to assess culpability, and whether any mental health disposal should be considered.
The guidelines, which come into effect on 1 October 2019, will help to ensure that sentencing by judges and magistrates will be consistent across the whole range of these offences. Limited guidance exists in magistrates' courts, but the new guidelines apply to all courts.
The new guidelines cover the following offences:
- Arson – criminal damage by fire
- Criminal damage / arson with intent to endanger life or being reckless as to whether life endangered
- Criminal damage where the damage has a value of more than £5000
- Criminal damage where the damage has a value of less than £5000
- Racially or religiously aggravated criminal damage
- Threats to destroy or damage property
Sentencing Council member Her Honour Judge Sarah Munro QC said:
"The Council's guidelines ensure that courts can consider all the consequences of arson and criminal damage offences, from a treasured family photo being destroyed to someone nearly losing their life and home in a calculated and vengeful arson attack."
Welcoming the new guidelines Mark Harrison, Head of Heritage Crime Strategy for Historic England, said:
"England's heritage can't be valued purely in economic terms. The impact of criminal damage and arson to our historic buildings and archaeological sites has far-reaching consequences over and above what has been damaged or lost.
"Damage to our heritage comes in many forms. Whether it be graffiti painted on the walls of a historic church, vandalism to the stonework of an ancient castle or causing a fire that devastates a Medieval barn or Victorian pier; these offences have a detrimental impact on both the historic property or site and the local community in which it is located.
"The new guidelines will help the courts identify all the relevant factors to include in their sentencing decisions as they will now be able to consider 'threats to cause criminal damage', 'the act of damage' and 'damage by fire'. It will also aid Historic England's work with the Police and Crown Prosecution Service when cases involve damage caused to heritage or cultural assets."
Neil Odin, Chair of the National Fire Chiefs Council Prevention Coordination Committee, commented:
"I fully support these new guidelines for dealing with arson attacks through the courts. Deliberate acts of arson are a blight on our local communities and have an economic impact on businesses.
"In addition, damage and the loss of historical buildings is disruptive and impacts on our vitally important heritage. Arson also increases demands on the already stretched resources of fire services across the country, which can result in diverting resources away from other incidents.
" It is worrying to see that there has been an upward trend of arson since 2014/15 and while we will continue with prevention work to reduce these figures, it is important the courts can deal with criminal damage appropriately, sending a clear message to other people."
Justice Minister Robert Buckland said:
"Beyond the financial cost to victims, arson and criminal damage are serious offences which can risk lives and leave lasting psychological harm.
"So it is right that courts have clear and consistent guidance when sentencing offenders to ensure punishments properly fit the crime."

Mark Martin on the Big Three
Salinity, pH and Temperature in the Reef Aqaurium
In a reef tank, the big three—salinity, temperature and pH—are far more important than in a fish-only system, but every aquarist should shoot for stability in these three parameters. Every single tank crash in the history of aquaria has been a direct or indirect result of a lack of stability in one or all of the big three. It is funny when you think about—there are just three parameters you really need to watch, and yet so many people simply don't. I mean, sure, it is important to look at nitrates and calcium in a reef tank, but if you ignore the big three long enough, it does not matter if you have 500ppm calcium or 0ppm nitrates. The tank will eventually crash. So what can you do today to get the big three taken care of? Read on.
Use a Chiller, Heater and Controller to Maintain Temperature Stability in a Reef Tank
Temperature stability is essential to a reef tank. Fluctuations in temperature of only a few degrees every 24 hours creates environmental stress for your animals. The stress, while perhaps not deadly in and of itself, will, over time, make your animals more susceptible to disease and infestation. Instead of dumping money into expensive nitrate reactors or calcium reactors, most beginning reef aquarists would derive far more benefit by buying a chiller. Using a quality chiller in conjunction with a heater and a reliable controller will insure minimal temperature fluctuation in your aquarium.
Keeping Salinity Stable in a Tropical Marine Aquarium
In a reef or invertebrate tank, many of the animals are particularly sensitive to changes in salinity. Falling behind on topping-off your aquarium with freshwater can cause the salinity to increase gradually. While this usually does not present a huge problem, when you suddenly "catch-up" with tank maintenance, and replace five, ten or more gallons of freshwater all at once, the salinity drops back down to normal levels but much too quickly for many inverts. Investing in an automatic top-off system can make all the difference in terms of keeping your tank's salinity stable.
Dealing with pH Fluctuations
A normal daily cycle of pH fluctuation occurs in most aquaria secondary to the lighting schedule. While this is not a disaster, in most cases, the savvy aquarist can easily stabilize this parameter by simply installing a refugium that runs on an alternate light cycle. Keeping the refugium lights on when the display tank's lights are off will insure a more stable pH over an entire 24-hour period.
Install a Chiller, Automatic Top-Off and a Refugium Today!
New reef aquarists, like all aquarists, should focus first and foremost on the big three: temperature, salinity and pH. Investing in a chiller, an automatic top-off system and a refugium can go a long way to creating a stable reef environment that will quickly mature into a full-blown reef aquarium.
