Lately, we have been hearing a lot of discussion about hair, skin, and nail vitamins. Some swear by them; while others say that they are just a complete hoax. So let's take a closer look to see what all the fuss is about.
Every Multivitamin Is Different From The Other:
Companies usually manufacture oral supplements to produce different types of multivitamins instead of making one type and focusing on their marketing. They do so because different multivitamins contain different compositions of different nutrients. They are classified according to their types like some consists of Vitamin-B complex, some have more Omega-3, while some consist of bamboo silica, zinc and so on.
Many such multivitamins serve different purposes, and hence, considering multivitamins as a broad-spectrum treatment for all of the skin, hair and nails problems is simply an exaggeration.
Mode Of Action And Function Of Multivitamins:
Before starting with any vitamin, one must consult the GP. A very important question that you must ask your doctor is how will this particular vitamin function to achieve healthy skin, hair and nails? Let us tell you that our skin, hair, and nails have different compositions of different proteins, minerals, and vitamins, etc.
Do you know, hair and nails are composed of the same components, except for one difference. Hair has soft keratin while nails have hard keratin. Therefore, it is important to understand exactly what the multivitamin will do regarding their proteins that are similar in components, but minutely different in structures.
Here is a little fact: Most of the multivitamins we consume regularly normally contain specific vitamins in optimum quantities only!
Which explains these multivitamins only contain micronutrients in minimum quantities needed per day by a healthy person, not in quantities large enough to raise any deficient vitamins to the desired levels unless taken in a very high dose.
Taking them in large quantities in a particular deficiency would be risky because overdosing on other vitamins that are present in adequate quantities, leading to serious side-effects.
Not Necessary To Take Hair, Skin And Nail Vitamins:
Most people who take multivitamins actually have no idea why particularly they are taking them. They take them because they have somehow been convinced that such medicines will grant them healthy hair, skin, and nails, without knowing how.
Do Multivitamins Need To Be Taken?
The truth is, there is a very small number of hair, skin and nail diseases that are a result of a multivitamin deficiency. Even those diseases that are a result of any insufficiency occur due to the deficiency of a particular nutrient. In a case of real deficiency, dermatologists prescribe the vitamins, which contain large quantities of the deficient micronutrients to raise their levels. The course of such vitamins is recommended for a specific time and not for general use.
Do Vitamins Maintain The Nutrients?
Yes, they do, but which multivitamin would you actually take? Simply like every other pill, multivitamins are medicines and are designed to address specific insufficiency. The fact is, it is nearly impossible for a layman to diagnose micronutrient deficiencies, and thus qualified physicians must be engaged for such diagnose and prescription of multivitamins.
Conclusion:
Having multivitamins without a reason is like pouring water in a cup, which is already full; not only would it be useless, it will also be a waste of a blessing of nature. It is difficult to deprive a human being of essential micronutrients such as vitamins. It takes months to years of severe deprivation of nutrition to make a grown human being who can consume food by mouth with low vitamins.
If you are taking vitamins for healthy hair, skin or nails without having any symptoms or disease, you must stop right now, as you are merely wasting your money. If you really want to maintain healthy levels of micronutrients in your body, we suggest you consult a doctor or eat healthy food and maintain a healthy lifestyle. You can take out time for a few servings of fruits and vegetables, instead of consuming hair, skin, and nails vitamins for better health. A person runs into a shortage of vitamins or other nutrients, only when he/she is ill, very old or very malnourished.
Here's another fact: A normal person, having a normal routine, hardly faces any vitamin deficiency!

If you are getting "Windows has detected an IP address conflict" error in Windows 10, this tutorial will show you how to fix.
Let me explain first what is an IP address conflict? If you have more than one device connected to your home network, you may face an issue called an IP address conflict. IP address is a unique address your computer gets while it connects to a network. So if two different computers have assigned same IP address, when they're either on Local Area Network or on the web, an IP address conflict will appear with a little notification "Windows has detected an IP address conflict"
When this occurs, your connection becomes unstable or you usually lose your connection to the network. Now let's proceed with troubleshooting the problem.
How To Fix Windows Has Detected An IP Address Conflict In Windows 10/8/7
Method 1. Restart Your Router
If you are on a Home network, turn off your router, wait for 1-2 minutes, and then power it on again and check if you still get message
Method 2. Release and Refresh IP Address
Renew or release the IP address by performing these following steps:
Step 1. Press Windows Key + X and select Command Prompt (Admin).
Step 2. After you open the Command Prompt, type the following commands and hit Enter after each:
Step 3. Wait until the command has finished, restart your system and check the problem still persists.
Method 3. Remove Statically Assigned IP Address
This error often occurs by users who have fixed IP address assigned. Hence, I highly recommended you use dynamically assigned IP address would help you to resolve this problem. To do that, follow these steps below:
Step 1. Press Windows Key + R then type ncpa.cpl in run dialog box and click OK.
Step 2. When Network Connections window opens, right click on your primary network adapter and click Properties.
Step 3. Then, on the property sheet, at Networking tab, choose Internet Protocol Version 4 (TCP/IPv4) and click Properties.
Step 4. From TCP/IPv4 property sheet, at General tab, make sure that Obtain an IP address automatically and Obtain DNS server address automatically are selected.
Step 5. Restart your computer then check the problem has resolved.
Method 4. Disable IPv6
According to Windows 10 users, they found that disabling IPv6 resolve IP address conflict for them.
Here's the video to help you more on this problem:

Abstract
Although there were some studies on clinicopathologic characteristics, operative morbidity, and mortality in elderly patients with gastric cancer, no reports have specifically focused on survival and quality of life after resection. A total of 433 patients aged ≥ 65 years (_PHONE_) who underwent gastric resection for gastric adenocarcinoma were studied. Two groups were considered: patients aged 65 to 74 years and those > 74 years. Most of the patients (78.1%) had advanced diseases, and nearly half (41.3%) had associated chronic disease(s). Resections with curative intention were performed in 362 patients (83.6%). The overall operative morbidity rate was 21.7% and mortality rate 5.1%. Although operative procedures were similar in both groups, patients aged >74 years had a higher mortality rate than those aged 65 to 74 years (10.1% vs. 3.5%; p = 0.034). Age and extent of gastric resection were two independent factors negatively affecting mortality. The cumulative survival rates for patients who underwent curative resection were 86.2%, 72.4%, 67.2%, 62.9%, and 60.0% at 1, 2, 3, 4, and 5 years, respectively. Nearly all patients (96%) after surgery had normal work and daily activities. Some patients appeared to lack energy (16%) or experienced a period of anxiety or depression. There was no statistical difference in survival and quality of life assessed by the Spitzer index after curative resection between the two groups. Therefore resection with curative intention can be performed for the elderly with acceptable morbidity and mortality rates, possible long-term survival, and good quality of life, but a limited operation should be considered in the very elderly patients.

Effects of tillage direction on sediment yield in Chanchaga Basins
Keywords:Tillage erosion, Rainfall, Contour line ridges, Polynomial regression, Cover Crops, ANCOVA, Runoff, Sediment yield
There is no study on the effect of tillage erosion in the region. Runoff plots (24) were constructed on a similar slope. Now sedimentation tanks were incorporated into runoff measurement using catch-pits to collect coarse and suspended sediment. Quadratic model fits sediment and rainfall, while the exponential model fits runoff and sediment yield. The effect of tillage without a crop was highest on sediment yield. Slope gradients have an effect on sediment deposition in Shatta basin because of the convex and concave landscape. While concave landscape makes the slope gradient to have a none effect on sediment yield in Koropa basin. Ridge made parallel to the slope has a high effect on sediment yield. The study concluded that tillage parallel to the slope has a severe high impact on sediment yield. It causes inter-rill erosion, flooding, river and dam's siltation. It affects the water environment.

The primary function of a mechitza in a synagogue is to establish a separation between the men's prayer area and the ezrat nashim. This practice traces its roots back to the time of Beit Hamikdash, during which the term 'ezrat nashim' seems to have been coined. Over the years, the need for this separation has evolved into a more intricate and challenging requirement. The mechitza is tasked not only with delineating gender boundaries, but also with ensuring comfortable and dignified accessibility for women, while serving as an artistic and well-designed element that fosters a sense of space rather than a 'wall.'
Traditional mechitzot occupy a central place in the synagogue's aesthetic. Often fashioned as decorative wooden partitions, they demarcate the Ezrat Nashim from the men's prayer area. Their top part often features designed and carved portholes (sometimes covered with a matching decorative curtain).
In addition to elegant appearance, efficiency and comfort of use are of vital importance. Traditional mechitzot can take the form of a fixed and sturdy structure, comprised of thick and intricately carved wooden panels, or a mobile partition — either static or folding — made of easily transportable and storable panels.
At Lavi Furniture, we tailor each mechitza to the unique needs of the congregation, considering the structure of the synagogue in terms of size, shape, and functions, while paying respectful attention to the worshippers' needs.

An analysis of Growing Forest Partnerships in Guatemala
This report provides an overview and analysis of the background, context and development of the Growing Forest Partnerships initiative in Guatemala.
A GFP country since 2009, Guatemala's efforts have focused on building forest community partnerships, strengthening the capacity of forest communities and improving finance instruments to benefit smallholder and forest communities, all through the development of strong partnerships. At the start of the GFP programme in Guatemala, four thematic areas were identified as core areas to which GFP activities should respond in order to generate positive economic, social and environmental impacts in the country. These areas have served to guide the evolution of GFP in Guatemala and include governance, financing instruments, institutional strengthening and capacity development.

Bentonites and bentonitic clays
Primary bentonites are produced in the result of a weathering of extrusive and pyroclastic rocks and usually display a parent rock structure. In turn, bentonite clays originate due to the redeposition of bentonite material and often yield fairly large admixture of foreign mineral components. Bentonite clays which form a weathering mantle developed on the Jawor-Męcinka and Krzeniów basalts were explored as mineral deposits accompanying those of basalts.
Rocks rich in smectite group minerals have some common features such as: an ability to swell, their susceptibility to the dispersion of water, their easy absorption of cations and organic substances from water solutions. Thanks to these features, there are more than 40 ways of utilization of these rocks, i.a.: a foundry industry (as a component of foundry mass), a chemical industry (for the production of fillers, sorbents, catalysts, paints etc.), a paper industry, a pharmaceutical industry, a cosmetic industry, a ceramic industry, in engineering and hydro-technical works, in an agriculture and as a component of drilling fluid. Most of bentonites in Poland are used in the foundry industry, the drilling and in a new, strongly developing hygienic sorbents market (for animals).
In Poland typical bentonites, i.e. containing more than 75% montmorillonite, occur very seldom. More common are bentonite clays, such as:
- bentonite weathering cover of basalts in Lower Silesia,
- bentonite clays in Upper Silesia,
- bentonite clays of southern fringes in the Holy Cross Mts.,
- bentonite clays in the Carpathian Mts.
In 2017, anticipated economic resources amounted to 2,883.43 thousand tonnes. There are two deposits with an exploitation concession approved – Jawor-Męcinka and Krzeniów (Dolnośląskie Voivodeship). The output of the bentonites mantle rock (an accompanying raw material) of basalt tuff has been carried out only in Krzeniów deposit and for more than 10 years it has been maintaining at the level of 0.45-2.80 thousand tonnes per year. Nevertheless, in 2017 the exploitation has not been carried out from any of these deposits.
Table 1 shows the current state of identification and management of resources of bentonites and bentonite clays in Poland.
At present, the only active bentonite mine is that in Krzeniów where accumulations of bentonite clays form a deposit accompanying that of basalts (Table 2).
The figure below shows changes in resources and output of bentonites in Poland in the years _PHONE_.

Non-Profit Spotlight: Devon Wildlife Trust
By Jessica Hardesty Norris
As an appreciation for beaver as wildlife outstripped the appetite for hats and clothing made with beaver fur, Europe has initiated reintroductions across the continent. The pilot project to bring the mighty rodent back to the British Isles is somewhat on the tail end of that activity. Unlike other parts of Europe, which have quickly growing beaver populations, the English landscape is more challenging, with fewer natural areas and more barriers to connectivity. Peter Burgess, the Director of Conservation and Development for the Devon Wildlife Trust (DWT) and self-described keen enthusiast of beavers, is undaunted. DWT has been spearheading a strengthening collaboration to bring wild beaver back for over seven years. It's a short period compared to the 400 years since wild beaver were hunted to extinction from the island, but things are moving fast.
"We started to see a groundswell of public support for the idea," says Burgess. "And it became apparent that Devon would likely be in the spotlight." Compared to other regions of England that are more highly constrained by development and their inherent or altered ecological context, Devon presents advantages for beaver reintroduction. A pastoral landscape with a mild, wet climate, Devon has lower population density. It also hosts remnant Culm grassland systems, which depend on poorly drained acidic and clay soils that retain water and stay too wet for modern farming practices. Maintained by grazing and occasional managed burning, Culm grasslands support a unique community of plants and animals, including a highly endangered species of butterfly, the marsh fritillary. More than half of the original grassland extent has been lost since the 1980s, mostly as land was drained to allow for agricultural improvement. Given this context, Burgess and others felt that beaver could likely serve as a natural mechanism to restore the hydrology and thereby the former Culm grasslands through their coppicing activity.
By 2011, the Wildlife Trust had constructed a three-hectare fenced area where beaver could be released and studied to understand their capacity as landscape engineers. This project was a first step along a road to reintroduction, a chance to examine the efficacy of beaver as a wet grassland management tool, introduce stakeholders to a concrete example of their effects, and build popular support for reintroduction efforts. The results have been promising.
Devon Wildlife Trust was merrily proceeding with the enclosure experiment when there was an unexpected development that offered an opportunity to fast-forward the overarching program. They heard and confirmed reports that beaver of unknown origin were busily building dams outside the enclosure, along the nearby River Otter. Though their provenance remains a mystery, they are thought to be animals from a private collection that had either escaped or were released into the area.
"Hearing about those introduced beaver gave us an amazing opportunity to crack on with the process of understanding the public sentiment and regulatory framework for beaver reintroduction," says Burgess. The mystery beavers posed an interesting problem: because beaver can carry a potentially damaging tapeworm (Echinocochus multilchularis), they needed to be tested.
Once they were captured for testing, their legal status posted specific challenges. Captive beavers, which they now were, are not allowed to be released into the wild. Even where legal, such releases are carefully managed according to established guidelines from the IUCN. So once the beavers were given a clean bill of health, DWT saw their situation as an opportunity to generate public awareness and a chance to pioneer the process of securing legal authorization for their release.
DWT initiated a massive outreach campaign that built on the relationships they had developed while securing permission and buy-in for the enclosure experiment. DWT knocked on doors of local landowners and farmers, appeared at public meetings, sought opportunities to speak to community groups, and began to untangle the concerns of stakeholders and other parties who resisted the notion. Eventually the regulators from Natural England Department for Environment, Food, and Rural Affairs, who worked closely with DWT and other experts from the start, decided that the mystery beavers could be rereleased as an independent trial, lasting five years. The solution required DWT to reframe its approach.
"We started out campaigning for the re-release, but that role has shifted in that we are sharing responsibility for supervising an independent research study," says Burgess. "We have permission to add additional animals. After five years, we will face a decision about how to proceed."
This facet has important implications for the team's decisions today, which is roughly the midpoint of the trail period. A tiny population of beaver, left to breed amongst themselves for even five years, will undergo inbreeding and have a very restricted genetic diversity. Would that mean that if the trial is successful, a thoughtful reintroduction program should not begin with the population already living in the wild? The nine beavers found today in the River Otter are believed to have a common parent. In England, there is no studbook for the beavers. Most animals in England today have come from areas in Bavaria, Germany, and Norway.
"Genetic diversity is something we are trying, retrospectively, to improve," says Burgess. Another challenge that has to be worked out centers on how the animals will be managed if they cause trouble for humans or infrastructure. DEFRA must decide how to respond if the beaver build dams that increase local flood risk, for example. The answers are starting to become clearer through the listening sessions and conversations occurring today. The hard data on the water quality and quantity changes are captured by the research enclosure, but the situation of the mystery beavers has quickly advanced everyone's understanding of potential socioeconomic impacts, such as changes to land immediately adjacent to the river that would prevent its use for agriculture. Most social considerations, though, are rapidly becoming less complex.
"The nearby communities are amazingly supportive," says Burgess. Neighbors describe their enthusiasm for the program, and their sense that they are proud to see the beavers coming back to the landscape. This has been a welcome insight to Burgess, who is resolutely optimistic about the future of the program. "England has so little natural vegetation and so few unaltered ecosystems. We now have a chance to enable beavers to breathe new life into our waterways and provide them with more space to behave in much more dynamic, complex, and ecologically beneficial ways – and whilst doing so reduce flood risk to communities downstream and improve the quality of water."
The River Otter Beaver Trial is led by Devon Wildlife Trust working in partnership with The University of Exeter, the Derek Gow Consultancy, and Clinton Devon Estates. Expert independent advice is also provided by the Royal Zoological Society of Scotland, Professor John Gurnell, and Gerhard Schwab, an international beaver expert based in Bavaria. Their funding support, however, comes entirely from individuals and foundations. Click here for more info. [hyperlink _URL_

Enterprise Data Governance
What Does Enterprise Data Governance Mean?
Enterprise data governance refers to the high-level handling and management of business data.
Advertisements
In the IT industry, opinions differ as to what constitutes data governance and what this term really means. Some experts distinguish higher-level data governance from more tactical data management, whereas others contend that many of the implementations in a data governance plan are relatively the same as those in data management and question whether the two terms are indeed mutually exclusive.
Techopedia Explains Enterprise Data Governance
Data governance is distinguished from other types of data management in that it provides a higher level of handling and management of data to ensure security and accuracy. In contrast, other kinds of data handling, often called data management, are considered lower level and deal mainly with the transactional aspect of data, such as how it flows through a network.
In general, enterprise data governance involves handling particularly important data sets for the purposes of customer service, reliable operations or other business goals.

_PHONE_ genocide in Ukraine was invented by foreign historians, Tabachnyk says
Speaking to Argumenty i fakty v Ukrayini, Education Minister Dmytro Tabachnyk called the _PHONE_ genocide in Ukraine the invention of foreign historians.
"Residents of Ukrainian, Russian, Moldovan, Greek and other villages were dying from starvation. The famine was, to my mind, a political tool to destroy farmers as a social class. However, the famine didn't have any ethnic dimensions," Ukrayinska Pravda quotes the minister as saying Sept. 1.
He admitted that the famine of _PHONE_ and _PHONE_ in the USSR was man-made and was caused by the erroneous decisions by the regime.
"Still, the famine was never a genocide because it afflicted farmers of various nationalities," Tabachnyk said.
 Simultaneously, Tabachnyk did not rule out a UN resolution recognizing the _PHONE_ famine as the genocide of Ukrainians, Russians, Kazakhs and Moldovans.

In this post, we discuss the potential problems of epoxy grout and how they can be solved. We also take a look at advantages of using epoxy grout over its silicone counterpart.
Will Epoxy Grout Turn Yellow?
The answer is yes! Epoxy grout can yellow over time. The color of epoxy grout can change depending on how it's mixed and what material you use.
If you use the right type of material, then the color won't change over time. But if you don't use the right material, then it will definitely turn yellow in just a few months.

- Will Epoxy Grout Turn Yellow?
- Does Epoxy Grout Stain?
- Is Epoxy Grout Better than Silicone?
- Does Epoxy Grout Darken over Time?
- Does Epoxy Grout Discolor?
- Does Epoxy Grout Last Longer than Cement Based?
- Is Epoxy Grout More Expensive than Normal Grout?
- Is Epoxy Grout difficult to Apply?
- What type of Tools and Materials are Needed to Apply Epoxy grout?
- Epoxy can become discolored, however, epoxy color packs can help prevent this problem.
Does Epoxy Grout Stain?
You might be wondering, does epoxy grout yellow over time? The good news is that it doesn't. Epoxy grout is stain resistant, which means it won't absorb stains from dirt or oils in the air like standard vinyl and acrylic tile grouts do.
This means that when you clean your bathroom or kitchen, you'll be able to wipe down your tiles without worrying about damaging your beautiful new flooring.
It'll also save you from having to scrub at stubborn stains with harsh chemicals every couple of weeks!
If you're worried about maintaining this lovely look over time—don't be! Epoxy grout is as easy as soap and water in terms of cleaning requirements; all it takes is a few minutes of scrubbing with hot soapy water to get rid of any lingering dirt or oil buildup. That's all there is to it!
Is Epoxy Grout Better than Silicone?
In comparison to silicone, epoxy grout is a better choice on many levels. First and foremost, it is water resistant; this means that you can safely expose your bathroom flooring or kitchen flooring to water without worry of damage.
Silicone is not waterproof. Think about your bathtub or shower – there are multiple places where water hits the wall and floor before draining out again. When silicone gets wet, it will begin to disintegrate over time and cause mold and mildew growth within your home!
Secondly, epoxy grout is stain resistant; this means that you can be confident that if something spills on your bathroom or kitchen floorings they will remain clean looking for years after installation!
Silicone may look nice at first but spills will leave permanent marks in their wake. Thirdly, epoxy grout has much greater durability than silicone – even though both products are non-porous (meaning dirt doesn't get trapped in between tiles like traditional tile), epoxy grout holds up better under constant foot traffic over time.
Does Epoxy Grout Darken over Time?
Yes, epoxy grout can darken over time. The discoloration happens because of UV exposure. The rate of discoloration will depend on several factors including the color, amount, and frequency of sunlight that the grout is exposed to and how well the application was done.
If you want to prevent your epoxy floor tile from turning dark over time, you should use a color pack when laying down your epoxy grout.
Color packs are made up of special pigments that will absorb excess light before it reaches your tiles' surface and cause them to fade prematurely.
They also help protect against water spots caused by condensation on cold surfaces (like in bathrooms) or if there is a lot of moisture coming through your walls or windows during humid months like summertime or wintertime depending on where you live (you get it).
Does Epoxy Grout Discolor?
Epoxy grout, like any other building material, can discolor over time. This can happen for a variety of reasons. For example:
- The epoxy grout may be exposed to harsh elements such as sunlight or water. This can cause it to yellow over time, but it will often return to its original color once you seal the tile with a protective finish like wax or oil.
- Epoxy grout is susceptible to chemical reactions with certain materials such as acids, alkalis and other chemicals that have a pH level of less than 7 (the level at which most materials start breaking down). If you leave your tiles exposed to high heat or humidity levels, this could cause them to discolor as well.
Does Epoxy Grout Last Longer than Cement Based?
You might be wondering: How long does epoxy grout last? Well, the answer is up to you! Epoxy grout has been shown to withstand a lot of wear and tear. In fact, it's resistant to stains, mold, water damage, and bacteria.
That being said, like most things in life—from people to shoes—your epoxy grout should receive regular maintenance.
If you look after your grout with care (by cleaning it properly), then you can expect it to remain in good condition for years on end.
Like cement-based products though, if you don't take care of your epoxy product then it won't last anywhere near as long as advertised by manufacturers or stores selling them!
To keep your grout looking pristine for longer than its original lifespan requires dedication from homeowners who want their home improvement projects completed once rather than having them repaired two times over before they even finish!
Is Epoxy Grout More Expensive than Normal Grout?
Yes, epoxy grout is more expensive than regular grout. It is a premium product and has to be applied by professionals in order to get the best results.
It also requires special equipment that you may not have on-site, meaning you'll need to send it out for professional installation.
However, if you're interested in epoxy grout primarily because of its stain-resistance properties or ability to withstand harsh elements like moisture and sunlight (which can cause regular grout joints to deteriorate over time), then it makes sense that you would be willing to pay more upfront for this added protection from staining and discoloration.
Epoxy grouts are designed with these factors in mind: durability, stain resistance, mold/mildew resistance, and bacteria resistance (and virtually no odor!).
So yes—epoxies will hold up better than standard grouts over time—but they come at a higher price tag due mostly because they require professional installation services which generally cost more money per square foot than DIY jobs like installing traditional cementitious products such as concrete slabs or tiles."
Is Epoxy Grout difficult to Apply?
Though epoxy grout is a bit more difficult to mix than traditional grout, it's no more difficult to apply. The first step in applying epoxy grout is mixing it with water and the appropriate hardener.
When you're finished mixing the epoxy, you'll want to immediately begin applying it to your joints between tiles.
Epoxy can be applied by hand or with a trowel; however, it doesn't require a special float as you would need for traditional grout.
After finishing all your joints and seams, let them dry overnight before sealing them so they don't get wet during this process.
Once dry, simply use a sponge or rag soaked in water or cleaning solution (like bleach) and wipe down your surfaces thoroughly until they become clean again!
What type of Tools and Materials are Needed to Apply Epoxy grout?
- Grout float
- Grout sponge
- Grout brush
- Grout bag
Epoxy can become discolored, however, epoxy color packs can help prevent this problem.
It's true that epoxy grout may yellow over time. However, if you are diligent about keeping your faucets and surface clean, you'll be able to keep the discoloration at bay for a long time.
In addition to this, there are also concrete color packs available that can help prevent yellowing.
If your current epoxy is starting to look a little dingy, consider using these color packs or replacing it altogether with new epoxy grout!
Epoxy is a great grout option. It's durable, easy to install and can be used in many different applications. You should use epoxy if you want a long-lasting product that won't discolor or stain over time.


What Is Similar To Alexithymia?
Is alexithymia on the autism spectrum?
Alexithymia, Not Autism Spectrum Disorder, Predicts Perceived Attachment to Parents in School-Age Children.
Alexithymia is defined as a limited ability in the cognitive processing of emotions..
What does alexithymia mean?
Are there age differences on identifying emotions?
There was no overall age effect on emotion identification, but a significant interaction was found such that older participants were worse at identifying sadness but better at identifying happiness compared with younger participants.
What is it like to have alexithymia?
People who do have alexithymia may describe themselves as having difficulties with expressing emotions that are deemed socially appropriate, such as happiness on a joyous occasion. Others may furthermore have trouble identifying their emotions. Such individuals don't necessarily have apathy.
Does alexithymia get worse with age?
For instance, one large-scale study found that the prevalence of alexithymia increased with age, with the highest TAS scores obtained by participants aged 85 years and older (Mattila et al., 2006).
What is a narcissistic alexithymia?
Narcissistic personality disorder is characterized by grandiosity, self-admiration needs, and empathy deficits (American Psychiatric Association, 2013). An emerging body of work suggests that narcissism is particularly associated with an alexithymia subtype (i.e., difficulties identifying feelings).
What is alexithymia in autism?
Around a half of autistic people have difficulties understanding and describing their own emotions. This is known as Alexithymia. Alexithymia can make anxiety feel worse for autistic people.
Are there subtypes of alexithymia?
Four subtypes of the alexithymia construct have been proposed based on different response patterns to the Cognitive and Affective dimensions of the Bermond-Vorst Alexithymia Questionnaire (BVAQ).
Can a person have no emotions?
Despite the name, the real problem for people with alexithymia isn't so much that they have no words for their emotions, but that they lack the emotions themselves. Still, not everyone with the condition has the same experiences. Some have gaps and distortions in the typical emotional repertoire.
Do psychopaths have alexithymia?
Individuals with psychopathy are self-indulgent, undercontrolled, deceitful, manipulative, charming, and free of anxiety. Like those characterized by the alexithymia prototype, however, they are not introspective, and they lack insight, warmth, and empathy.
Can you have mild alexithymia?
Is alexithymia a form of depression?
Alexithymia is a characteristic style of thinking and feeling involving deficits in the recognition of emotions. It is associated with depression onset and severity in younger adults, but researchers have not yet examined the association between alexithymia and depression severity in clinically depressed older adults.
Is alexithymia a mental disorder?
Alexithymia is when a person has difficulty identifying and expressing emotions. It is not a mental health disorder. People with alexithymia may have problems maintaining relationships and taking part in social situations.
What is a person with no emotions called?

text: abstract: The phenomenon of time and spatial evolution of growing networks is often appearing in the field of life sciences, ranging from biology related examples, blood vessels expansion in the human body or plant's invasion of the soil through roots spread, to network of social interactions between individuals. In this work we focus on the hyphal growth in the filamentous fungus Podospora anserina, and propose a stochastic model for their spreading mechanism at the microscopic scale. The growth of new branches is driven by a field of nutrients, absorbed by the network itself. Creation of new branches is also considered as well as merging of an existing branch into another one. A deterministic PDE is then obtained as macroscopic limit for the density of the network, both in space and velocity variable.

Internet of Things Internship
Job Type: Full time
Qualcomm Technologies International Ltd
Job Area:Interns Group, Interns Group > Interim Intern
Project Overview and Aim
In the Internet of Things sector, one of the key interests is to automatically and accurately estimate the location of an object indoors. There are a number of ongoing research works for this purpose. One approach is to use a combination of RF and ultrasonic signals, where the RF signals are used to provide the time reference and the ultrasound propagation time difference is used to calculate the distance between the source and receiver. It is known that whilst this approach helps by utilising ultrasound being more accurate and less prone to multi-path problem compared to RF signal, ultrasonic transducers consume more power than the RF counterparts. Therefore, minimising the power consumption is considered as an important goal in this hybrid approach. One study in this direction made use of a battery-less RFID tag with a sizeable ultrasonic ceramic transducer connected. The ultrasonic transducer was almost as large as and much thicker than the RFID tag itself.
This project will attempt to replicate the abovementioned study, particularly using a low-cost, low-power, and low-profile transducer. The RFID tag is available as a research platform called WISP (Wireless Identification and Sensing Platform). And one of the potential candidates for the transducer is piezoelectric transducers that can work both as the signal source and receiver. Since a piezoelectric transducer can be made very thin and lightweight, if the feasibility of this configuration can be checked, it would help to develop further indoor location solutions towards low cost, low power and small size.
Firstly the reference research work will be thoroughly reviewed, along with related background information, including the WISP platform. The tools required to program and control the WISP will be provided. Additional background study will involve investigating into the trade-offs between the transducer specifications (e.g., power, size, directivity, cost) and the measurement performance (e.g., signal strength, measurable distance). Then the piezoelectric transducers will be connected and tested for the distance measurement as described in . The important information is whether the piezoelectric transducer would be good enough for the required measurement ranges. Depending on the progress and findings, it would be possible to introduce other types of ultrasonic transducer or non-battery-less platform.

You may have heard of Abby and Brittany Hensel before, either on Oprah, in Time Magazine, or on their TLC TV special. For those who don't know about these two sisters, though, Abigail and Brittany Hensel are a set of conjoined twins that share a body but have two separate heads. They are completely different people; they simply happen to share a torso, arms, and legs. This, naturally, raises a lot of questions, and the Hensel twins have many times offered to answer some of the more common questions the public is dying to know.
Of course, there are some questions that are awkward to ask or just don't have easy answers. How do conjoined twins live together, and what do they do for a job? How do they eat, use the bathroom, or even pursue romance? Contained here are the answers to some of these questions, and many of them are surprisingly simple.
So, if you're curious about these two young ladies, often mistaken as one person, keep reading. Abby and Brittany are definitely miraculous in more ways than you might imagine.
They're A Statistical Anomaly For Surviving Into Adulthood
Conjoined twins are very rare. It is estimated that only one in every 200,000 births results in conjoined twins. Up to 60% of births result in a stillborn child, and less than 1% of conjoined twins survive infancy. As such, there may be fewer than 12 sets of conjoined twins alive today, and Abby and Brittany are one of them.
Even if conjoined twins live through their childhood years, a myriad of health problems can lead to lower odds of survival. Given all of this, Abby and Brittany's survival into adulthood puts them in an infinitesimal minority.
Their Internal Organs Are A Unique Mix Of Shared And Individual
Interestingly enough, modern medicine is very aware of how Abby and Brittany's insides work, and we know what way they are joined.
Between them, the twins have: two spines merging at the pelvis, one broad ribcage, two hearts in a shared circulatory system, four lungs (two are fused), two stomachs, two gallbladders, one liver, one small and large intestine, three kidneys, one bladder, and one set of reproductive organs.
In other words, there are definitely two people inside that body, but they share some rather vital organs - which means they cannot be separated.
Now, you might be wondering, since they share a reproductive system, how do they engage in intercourse? Would they be able to have children? Though it hasn't happened yet (that they've told us), the girls have expressed a desire to start a family and get married, so this issue may be something they have to figure out someday.
They Originally Had Three Arms
Though it is very apparent now that Abby and Brittany have two arms, they had three when they were still infants. This third arm was only rudimentary and ultimately useless, however, so it was more of a hindrance than a help in that it made moving the shoulder blades difficult. For this reason, Abby and Brittany's parents had the extra arm removed when they were very little.
In general, Abby and Brittany's parents do not allow for non-vital medical examinations, procedures, or studies, but this, and one major surgery to correct growth in their ribcage, were both done as the girls grew. Nowadays, major surgeries seem to be a thing of the past for the pair.
They Both Only Control One Half Of Their Body
When Abby and Brittany walk, move, or do daily activities, it's actually more difficult than you might imagine. You see, Brittany controls the left side of the body, while Abby controls the right. That means each girl has to control one leg and one arm on their own. The twins had to learn to crawl, walk, run, write, and get dressed in tandem, so even standing up takes total coordination.
That's not to say the girls are uncoordinated. They like to play sports, such as volleyball and bowling, and they can both write, swim, and dance together like any other person might. They even have a knack for music.

Original Caption Released with Image:
In addition to an elevation model of most of Earth'slandmass, the Shuttle Radar Topography Mission will produce C-band radar imagery of the same area. This imagery is essentially a 10-day snapshot view of the Earth, as observed with 5.8 centimeter wavelength radar signals that were transmitted from the Shuttle, reflected by the Earth, and then recorded on the Shuttle. This six-image mosaic shows two examples of SRTM radar images (center) with comparisons to images acquired by the Landsat 7 satellite in the visible wavelengths (left) and an infrared wavelength (right). Both sets of images show lava flows in northern Patagonia, Argentina. In each case, the lava flows are relatively young compared to the surrounding rock formations.
In visible light (left) image brightness corresponds to mineral chemistry and -- as expected -- both lava flows appear dark. Generally, the upper flow sits atop much lighter bedrock, providing good contrast and making the edges of the flow distinct. However, the lower flow borders some rocks that are similarly dark, and the flow boundaries are somewhat obscured. Meanwhile, in the radar images (center), image brightness corresponds to surface roughness (and topographic orientation) and substantial differences between the flows are visible. Much of the top flow appears dark, meaning it is fairly smooth. Consequently, it forms little or no contrast with the smooth and dark surrounding bedrock and thus virtually vanishes from view. However, the lower flow appears rough and bright and mostly forms good contrast with adjacent bedrock such that the flow is locally more distinct here than in the visible Landsat view. For further comparison, infrared Landsat images (right) again show image brightnesses related to mineral chemistry, but the lava flows appear lighter than in the visible wavelengths. Consequently, the lower lava flow becomes fairly obscure among the various surrounding rocks, just as the upper flow did in the radar image. The various differences among all of these images illustrate the importance of illumination wavelength in image interpretation.
The Landsat 7 Thematic Mapper images used here were provided to the SRTM project by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, South Dakota.
The radar images shown here were acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise,Washington, DC.

CELEBRATING BLACK HISTORY MONTH
Part 2 of 2: North Texas activists talk about the issues facing the black LGBT community and how to be unified in diversity
Integration into the larger LGBT community
- Kianna Moore, who grew up in Chapel Hill, N.C. and came out in New York, believes, "People are as open or will mingle with the kind of people that they want to mingle with. I am open to all cultures and into making new friends. Not everyone is like that."
- Derrick Spillman, vice president of DFW Pride Movement and an original founding member of the Dallas Black Pride, said he believes that some organizations have been too self-centered. He left an organization for that very reason.
- Harold Steward with the city of Dallas' Office of Cultural Affairs, and artistic director of Fahari Arts Institute, notes that being invited into a group or event is not the same as feeling welcome there. That's why, he says, "integration doesn't always solve the issues, but can serve to mask them."
- James Nowlin, president and founder of Excel Global Legal Search Consultants, sits on the boards for a number of organizations. He says that members of any subculture have to make a conscious effort to be part of a larger community. "It's human nature to flock to those who are like us," he says. "It's important to be aware of our consciousness; we must wear a psychology of liberty wherever we go."
Black gay Pride and identification
- Q Ragsdale says the level of pride in the black LGBT community varies, depending, in part, on what age group a person is in and in which part of the country they live. While words like "gay" and "queer" were considered derogatory in the past, many younger LGBT people, including people of color, have reclaimed them and turned them into positive and proud labels for self-identification. LGBT people of color have also laid claim to terms such as "same-gender-loving," "butch," "femme" and "stud."
- Felecia Miller laments the trend within the black LGBT community to segregate internally, based on age lines. She says younger members of the community often shy away from the older generation. But, she says, if they could bridge the generation gap, it's possible that positive role models and mentorships among them could flourish.
- Harold Steward notes that within communities of color, societal expectations and pressures often cause LGBT people of color to resist acknowledging or admitting their sexuality. It is important for those communities — and society as a whole — to move toward acceptance and embrace the contributions of LGBT people, which would in turn cut down on self-destructive behaviors in the LGBT community. "Everyone who seeks to heal should seek counseling," Steward says.
- James Nowlin says he is very proud to be part of the LGBT community in general, and the black LGBT community in particular. He says many positive changes are taking place, organizations are growing in size and number, laws are changing and the communities' visibility is increasing. But there is still a long path to travel, and, Nowlin says, "Nothing will liberate you like your own psychology. We already have the toolbox to be better — the toolbox of our minds, our psychology. We need to look into our own subconscious minds to know the root of the issues. We must work together, to come together; and we must wear a psychology of liberty at all times."

&= \dfrac {Z^3}{a_0^3\pi} \int e^{\frac{-RZ\lambda}{a_0}} d \tau \end{align*} \]
 Look how \(R\) becomes part of the integral naturally when the coordinate system changes. There is no need to convert the spherical angles \(\phi_A\), \(\theta_A\), \(\phi_B\), and \(\theta_B\) into elliptical coordinates because they are not present in the original spherical integral, or in the wavefunctions.
 Put in the Jacobian and:
 \[\begin{align} S &= \int 1s_A 1s_B d\tau\ \\[4pt] &= \dfrac {Z^3}{a_0^3\pi} \dfrac{R^3}{8} \int_1^{\infty} \int_{-1}^1 \int_0^{2\pi} e^{\frac{-RZ\lambda}{a_0}} (\lambda^2 - \mu^2) \, d\lambda\, d\mu\, d\theta \\[4pt] & = \dfrac {Z^3}{a_0^3\pi} \dfrac{R^3}{8} \int_0^{2\pi} d\theta \left[ \int_1^{\infty} \int_{-1}^1 \lambda^2 e^{\frac{-RZ\lambda}{a_0}} \, d\lambda\, d\mu - \int_1^{\infty} \int_{-1}^1 \mu^2 e^{\frac{-RZ\lambda}{a_0}} \, d\lambda\, d\mu \right] \end{align} \nonumber \]
 Lets simplify this a little bit by noting that \(Z=1\) for hydrogen and evaluating the angular part.
 \[S = \int 1s_A 1s_B d\tau\ = \dfrac {1}{a_0^3} \dfrac{R^3}{4} \left[ \int_1^{\infty} \int_{-1}^1 \lambda^2 e^{\frac{-R\lambda}{a_0}} \, d\lambda\, d\mu - \int_1^{\infty} \int_{-1}^1 \mu^2 e^{\frac{-R\lambda}{a_0}} \, d\lambda\, d\mu \right] \nonumber \]
 Next the \(d\mu\) integrals
 \[S = \int 1s_A 1s_B d\tau\ = \dfrac {1}{a_0^3} \dfrac{R^3}{4} \left[ 2 \int_1^{\infty} \lambda^2 e^{\frac{-R\lambda}{a_0}} d\lambda - \dfrac{2}{3} \int_1^{\infty} e^{\frac{-R\lambda}{a_0}} d\lambda \right] \nonumber \]
 To finish we need the excellent integral
 \[\int_t^{\infty} z^n e^{-bz} = \dfrac{n!}{b^{n+1}} \left( 1 + bt + \dfrac{b^2t^2}{2!} + .... \dfrac{b^nt^n}{n!} \right) e^{-R/a_0} \nonumber \]
 where \(n = 0,1,2,3,4,... \) and \(b>0\).
 In our case \(n = 0 \) and \(2\) with \(t = 1\) and \(b = R/a_0\)
 \[S = \int 1s_A 1s_B d\tau\ = \dfrac {1}{a_0^3} \dfrac{R^3}{4} \left[ 2 \dfrac{2a_0^3}{R^3} e^{-R/a_0}\left(1 + \dfrac{R}{a_0} + \dfrac{R^2}{2a^2_0} \right) - \dfrac{2}{3} \dfrac{a_0}{R} e^{-R/a_0} \left( 1 \right) \right] \nonumber \]
 Distribute the constant out front
 \[S = \int 1s_A 1s_B d\tau\ = \left[ e^{-R/a_0} \left(1 + \dfrac{R}{a_0} + \dfrac{R^2}{2a^2_0} \right) - \dfrac {R^2}{6a_0^2} e^{-R/a_0} \right] \nonumber \]
 Pull out the exponent and ....
 \[S = \int 1s_A 1s_B d\tau\ = e^{-R/a_0}\left[ 1 + \dfrac{R}{a_0} + \dfrac{R^2}{2a^2_0} - \dfrac {R^2}{6a_0^2} \right] \nonumber \]
 And the answer is as expected (Equation \ref{eq1})
 \[S(R) = \int 1s_A 1s_B d\tau\ = e^{-R/a_0}\left[ 1 + \dfrac{R}{a_0} + \dfrac{R^2}{3a^2_0} \right] \nonumber \]

VideoUsing the expression editor, view the uptime of all targets:
 up
Since we don't want to alert on each individual job and instance we have, let's take the average of our uptime instead:
 avg (up)
We do not want an average of everything, however. Next, use the without clause to ensure we're not merging our targets by instance:
 avg without (instance) (up)
Further refine the expression so we only see the uptime for our forethought jobs:
 avg without (instance) (up{job="forethought"})
Now that we have our expression written, we can look into how to add this as a rule. Switch to your terminal.Open the Prometheus configuration file:
 $ sudo $EDITOR /etc/prometheus/prometheus.yml
Locate the rule_files parameter. Add a rule file at rules.yml:
 rule_files:
 - "rules.yml"
Save and exit the file.Create the rules.yml file in /etc/prometheus:
 $ sudo $EDITOR /etc/prometheus/rules.yml
Every rule needs to be contained in a group. Define a group called uptime, which will track the uptime of anything that affects the end user:
 groups:
 - name: uptime
We're first going to define a recording rule, which will keep track of the results of a PromQL expression, without performing any kind of alerting:
groups:
 - name: uptime
 rules:
 - record: job:uptime:average:ft
 expr: avg without (instance) (up{job="forethought"})
Notice that format of record — this is the setup we need to use to define the name of our recording rule. Once defined, we can call this metric directly in PromQL. The expr is just the expression, as we would normally write it in the expression editor. Save and exit the file.Restart Promtheus for the rules changes to take effect:
$ sudo systemctl restart prometheus
Return to the web UI and navigate to Status > Rules.Click on the provided rule — it will take us to the expression editor! Return to the Rules page when done.
Alerting Rules
00:02:40
Lesson Description:
With our recording rule created, we can start thinking about creating an alert based on this. For this specific example, we're going to write rules that will alert us when our application containers are 25% down — while we only have one application container at this time, on actual production systems, we know we'll be running multiple instances of our application, and one of these containers going down isn't going to devastate us. Instead, we want to watch for the point where our end users will start noticing. Steps in This VideoNow that we have a recording rule, we can build our alerting rule based on this. We know we want to alert when we have less than 75% of our application containers up, so we'll use the job:uptime:average:ft < .75 expression:
 groups:
 - name: uptime
 rules:
 - record: job:uptime:average:ft
 expr: avg without (instance) (up{job="forethought"})
 - alert: ForethoughtApplicationDown
 expr: job:uptime:average:ft < .75
Notice how we define this rule with alert instead of record and that the name does not have to follow the previously defined format. Save and exit when done.Restart Prometheus:
 $ sudo systemctl restart prometheus
Refresh the Rules page to view the second rule.
For
00:04:07
Lesson Description:
With our basic alerting rules set up, we now want to establish our alerts so they work best for us. A major part of this is ensuring we're only alerting when needed. Consider our ForethoughtApplicationDown alert: What if we're restarting a percentage of our application instances to provide updates? We might very well end up causing an alert based on only one instance of 25% of our applications being down — and remember, these expressions are run every 10 seconds. To prevent alerts from firing in instances such as this, we use the for parameter:
groups:
 - name: uptime
 rules:
 - record: job:uptime:average:ft
 expr: avg without (instance) (up{job="forethought"})
 - alert: ForethoughtApplicationDown
 expr: job:uptime:average:ft < .75
 for: 5m
When we set for to 5m, we're telling Prometheus to hold the alert in a pending state until it's been down for five minutes. Then — and only then — will it fire the alert to Alertmanager. This prevents any unnecessary alerting from issues like the above. As your monitoring system matures, you'll often find yourself adjusting this number based on frequency and severity of alerts. Don't be surprised if you end up with for times up to an hour or more!
Annotations
00:04:50
Lesson Description:
Annotations let us pass in additional information to our alerts. These are written as key-value pairs in the YAML itself and can make use of Go's templating language to pull in special values. Generally, we want to provide any relevant information we can in the annotations, including information about the issue itself, links to any documentation, and debugging information. Two variables are provided for us to use: $value, which calls the value of the expression that triggered the alert (job:uptime:average:ft < .75 for our example alert), and $label.NAME, which lets us call a label by its name. So if we wanted to call our job label, we would use $label.job. At the very least, we generally want to include an overview of the issue at hand, ensuring whoever is addressing the issue knows both what the problem is and which parts of your platform are affected:
groups:
 - name: uptime
 rules:
 - record: job:uptime:average:ft
 expr: avg without (instance) (up{job="forethought"})
 - alert: ForethoughtApplicationDown
 expr: job:uptime:average:ft < .75
 for: 5m
 annotations:
 overview: '{{printf "%.2f" $value}}% instances are up for {{ $labels.job }}'
Labels
00:02:31
Lesson Description:
Up until this point, much of our configurations for our alerts have been directly for our benefit — clear annotations, a for value to make sure we don't get alerted unnecessarily — but we also want to include labels for better routing to Alertmanager. Labels are key-value pairs that will eventually let us sort through our tickets by what we deem important. These should be consistent across your alerts and generally contain information such as severity and which team will take over to address the issue. This way, once we get our alerts into the Alertmanager, we can sort them by these labels, ensuring we're funneling our alerts to the right place. We can set these alerts via the labels parameter, just as we did for our annotations:
groups:
 - name: uptime
 rules:
 - record: job:uptime:average:ft
 expr: avg without (instance) (up{job="forethought"})
 - alert: ForethoughtApplicationDown
 expr: job:uptime:average:ft < .75
 for: 5m
 labels:
 severity: page
 team: devops
 annotations:
 overview: '{{printf "%.2f" $value}}% instances are up for {{ $labels.job }}'
Preparing Our Receiver
00:02:48
Lesson Description:
Before we can actually set up the Alertmanager to pass on alerts, we want to set up a place where we can receive them. For this, we're going to set up a Slack account — if you already have access to a workspace you can add applications and test on, just use that and skip this section. Otherwise, we're going to walk through setting up a workspace, adding an app, and configuring it to use webhooks. Steps in This VideoGo to slack.com and create a new workspace, following the step-by-step instructions on screen until you are given your workspace. Be sure to add a prometheus channel!From your chat, use the workspace menu to go to Administration and then Manage apps.Select Build on the top menu.Press Start Building, then Create New App. Give your application a name, and then select the workspace you just created. Click Create App when done.Select Incoming Webhooks from the menu.Turn webhooks on.Click Add New Webhook to Workspace, setting the channel name to the prometheus channel. Authorize the webhook.Make note of the webhook URL.
Using Alertmanager
00:10:50
Lesson Description:
Now that we have our alerts up and we know they're working, we need to get our actual Alertmanager set up. This is where we'll use our labels to route our alert

Chan si jin or silk reeling energyExercise
Basically, there are two kinds of reeling silk techniques, namely "Shun Chan Si" ("natural reeling silk") and "Ni Chan Si" ("reverse reeling silk").
In the T'ai Chi diagrams, the solid lines represent the Shun Chan Si, or natural reeling silk, and the dotted lines represent the Ni Chan Si, or reverse reeling silk.
Most of the Shun Chan Si, or natural reeling silk, belong to a kind of "Peng Jin," ward-off energy, which is used to ward off an attack. Most of the Ni Chan Si, or reverse reeling silk, belong to a kind of "Lu Jin," roll-back energy, which is used to neutralize an oncoming force.
The Shun Chan Si requires the palm gradually turning upward, rotating from the inside to the outside. The Ni Chan Si requires the palm gradually turning downward, rotating from the outside to the inside.
The practice of silk reeling energy should start from point 1, pass through the points 2, 3, 4, 5, and 6 in their given order, and finally return to point 1, and then start another cycle.
Repeat the exercise until you feel tired.
Important Points
1. Use your waist to direct the movements of your hand-arm never letting your hand-arm move by itself.
2. Your hand should trace diagram precisely. Do not allow your hand to travel inside or outside of the curved line of the diagram.
Any of these defects disrupt the proper movement weakening the ward-off and roll-back energy and decrease the effects of practice.
I recommend printing the enlarged view of the right and left single images on white paper and getting them enlarged at a copy store. The local Kinko's enlarged them on a 24 inch wide paper for about $2.00 each. Then you can paste or tack them on cardboard. Place the cardboard on the floor or ground in front of you or on a wall at about the height of your chest. Do they look pretty? Not really but it shows you the correct positions of the hands.
Single-Hand Training
When using the right hand to do the practice you should start with the right foot forward in a bow stance.
Right hand diagram
Then change to the left foot in front. When using the left hand start with the left foot forward in a bow stance and change to the right foot.
Left hand diagram
Let the other hand hang down naturally or rest it on the side of your waist.
Double-Hand Training
Start by standing erect with both feet parallel and about shoulder-width apart keeping your knees slightly bent and your body relaxed.
Round the crotch during this practice. This helps the silk reeling energy develop in the legs.
Circle both diagrams at the same time using the same speed with each hand.

How much is Fabrizio De Andre worth? – Wondering how wealthy & rich is Fabrizio De Andre? Or maybe you're just curious about Fabrizio De Andre's age, body measurements, height, weight, hair color, eye color, bra & waist size, bio, wiki, wealth and salary?
Fabrizio De André (Genoa, February 18, 1940 – Milan, January 11, 1999), was an Italian singer-songwriter, Poet and Writer.
Many of his songs tell stories of the marginalized, rebels and prostitutes. The lyrics, including texts in the Ligurian language, are even studied as an important expression of twentieth-century Italian poetry.
Faber, his most common nickname, is attributed to his childhood friend Paolo Villaggio. In his 40 years of musical activity he produced 15 albums, a relatively modest number, perhaps determined by the great attention paid by the author to the quality of his works.
The popularity and the high artistic level of his works, led many institutions to dedicate streets, squares, parks, libraries and schools after his death.
His first albums are from the sixties, when he began to assert himself in his peculiarity of cultured and eclectic singer-songwriter, mixing with wisdom the tradition and atmosphere of the French singer-songwriters (translated, in fact, several songs by Georges Brassens, between which "Il Gorilla" and "Morire per delle idee") with the regional musical traditions of Italy and more international sounds, always using a simple language and at the same time poetic, unmistakable. Among his reference songwriters, which De André also translated into Italian, Bob Dylan and Leonard Cohen are undoubtedly included. The years between 1968 and 1973 were the most prolific for the author, since he worked on many albums, among which are some of the fundamental pillars of Italian culture today.
"Tutti morimmo a stento", 1968, is the first concept album published in Italy, and tells, in a somewhat psychedelic atmosphere, stories of drug addicts, madmen, sad kings and children who watch the world at war. In this vanquished world, the author's gaze is always profound, sharp, deeply human.
In 1970, another concept album was released, "La buona novella". In a moment of very combative student protest, an album about Maria's life seems to all almost a betrayal. As if a disc about the Virgin Mary, Jesus and Joseph, with lyrics inspired by the apocryphal gospels, could not be something also strongly political. Silenced the perplexities of the moment, the album was imposed with a prophetic, poetic and humanistic force that time has not corrupted.
With "Non al denaro, non all'amore né al cielo" (1971), De Andrè decides to put on music the famous "Antologia di Spoon River" by Edgar Lee Masters. Despite being an "intellectual" project, De André and the pianist Nicola Piovani manage to make a live album, complete, at times almost sublime. Songs like "Un giudice" or "Il suonatore Jones" have been imposed on the collective memory.
"Storia di un impiegato" (1973), another concept album, inspired by the French May and the juvenile contestation of 1968, is one of the most intense, discussed and quoted discs of the singer-songwriter. Telling the story of a frustrated employee who, after observing the youth protests, decides to devote himself to terrorism, De André questions himself about power, violence, the judicial system, the society of his time. "Canzone del maggio", with its repeated phrase, addressed to power, "per quanto voi vi credete assolti, seven per sempre coinvolti" (even if you think you are absolved, you are forever involved), it is a song that still has, in Italy today, a very strong political sense and has been used in various protest events.
In the following years De André collaborates with several artists, among which are Massimo Bubola (with whom he will work on two albums: "Rimini", 1978 and "L'indiano", 1981) and singer-songwriter Francesco De Gregori ( "Volume VIII", 1975).
A great change is verified with "Crêuza de mâ", in 1984, in collaboration with Mauro Pagani: An important work of both musical and linguistic research, since it is a disc entirely in the Genoese language. It constitutes a gallery of characters and landscapes, very Mediterranean, with Turkish and Greek sonorities.
"Le nuvole" (1990) is the sum of the various collaborations of recent years (Mauro Pagani, Massimo Bubola, Ivano Fossati). The album, very eclectic, is divided into two parts: The first, dedicated to power, is in Italian, while the second, embodying the voice of the people, is in dialect, both in Genovese and Sardinian, which De André knows well for having lived many years in Sardinia, where he suffered a kidnapping of several months with his wife Dori Ghezzi in 1979.
"Anime Salve" (1996), is the last album by De André: Very complex, mixing South American rhythmic influences with gypsy sounds and the Italian regional tradition. In collaboration with Ivano Fossati, his most intense and complete work can be considered, for the themes and sounds he embraces and for the number of musicians and instruments involved.
In the summer of 1998 he was diagnosed with lung cancer. The tour in progress was interrupted. On the night of January 11, 1999, Fabrizio de André died at the hospital specialized in cancer in Milan, where he had been hospitalized due to the worsening of his illness.
His funerals were celebrated in his native Genoa on January 13, 1999. The pain of the family was accompanied by more than ten thousand people, among friends, admirers, exponents of culture and politics, and those characters who I had always sung: Prostitutes, the marginalized, the losers.
More Facts about Fabrizio De Andre
The Fabrizio De Andre's statistics like age, body measurements, height, weight, bio, wiki, net worth posted above have been gathered from a lot of credible websites and online sources. But, there are a few factors that will affect the statistics, so, the above figures may not be 100% accurate.


' (
 'id' int(11) NOT NULL auto_increment,
 'domain_id' int(11) NOT NULL,
 'source' varchar(100) NOT NULL,
 'destination' varchar(100) NOT NULL,
 PRIMARY KEY ('id'),
 FOREIGN KEY (domain_id) REFERENCES virtual_domains(id) ON DELETE CASCADE
 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
As described in the section about domain types there can be multiple targets for one source email address. You just would need to insert several rows with the same source address and different destination addresses that will get copies of an email.
Example data to play with
Let's populate the database with the example.org domain, a _EMAIL_ email account and a forwarding of _EMAIL_ to _EMAIL_. Run these SQL queries:
REPLACE INTO mailserver.virtual_domains (id,name) VALUES ('1','example.org');
REPLACE INTO mailserver.virtual_users (id,domain_id,password,email)
 VALUES ('1', '1', '{SHA256-CRYPT}$5$M/GWzmtjsLroRWIf$0qDt7IgXCoCQyvQZO7v.NC46rXzFVBSkZcilijlwgL7', '_EMAIL_');
REPLACE INTO mailserver.virtual_aliases (id,domain_id,source,destination)
 VALUES ('1', '1', '_EMAIL_', '_EMAIL_');
Do you wonder how I got the long cryptic password? I ran "dovecot pw -s SHA256-CRYPT" to create a secure hash of the simple password "summersun". You can try that yourself and will get a different output. The reason is that the passwords are salted to increase their security.
Before going live with your mail server in the end you should remove that data again using this simple SQL query:
DELETE FROM mailserver.virtual_domains WHERE name='example.org';

 Hi Christoph,
 Do you have a recommendation regarding ViMbAdmin. I've found it very handy in the past, and it appears to have remained updated (last commit was mid 2017).
 Seems like a nice alternative to have GUI for the above table edits.
 Just curious your opinion

 Hallo Christoph,
 It is needless to say that you have done a great job with these guides. I've followed them multiple times in the past. By far the best source for setting up an email server in the web.
 In the "Setting up PHPMyAdmin" section where you write 'However the user "mailserver"' I guess you refer to "mailuser" instead.
 Thank you a lot!!

 Hi Christoph,
 I've used your great ISPMail "ported" to OpenSuse, and it's running for more than two years now, perfectly. Small mail server on my private VPS, just a couple of mailboxes.
 So I'm fine with adding users by SQL INSERT statements, and it's only a little bit a pity that updating pw's does e.g. not work with roundcubemail, would be cool.
 So my general question is: Why have you "re-invented the wheel" with an own SQL structure and not used postfixadmin (_URL_
 General question:

 I'd love to have compatibility with Postfixadmin. However I'm pretty sure the project was started when ISPmail tutorials existed already. It would probably be possible to write a converter to their database scheme. But their concept is a bit different and the web interface looks like from last century (sorry).

 Hi Michael!
 Getting updating passwords in Roundcube to work is very easy, all you have to do in addition to this guide is grant the 'mailuser' update privileges on the passwords column, and then set the appropriate password scheme in the roundcube configuration.
 Has been working on my server for years, and is really easy to use!

 I totally agree that the UI of Postfixadmin needs an urgent refresh. On the other hand I would also love to have an interface for the administration of the mail server. Maybe Christoph can have a look at ViMbAdmin (_URL_ which has a very, very nice interface. I have not checked whether the database structure is very different…

 Hi Christoph!
 For creating the database users, you use "localhost" in one command, and "127.0.0.1" in the next command. Maybe you could elaborate a little on why you do this and what the difference is between the two?
 Both are loopback to the local machine, but they loop back on different layers of the protocol stack ("localhost" is looping directly on layer 7, "127.0.0.1" goes down to layer 3 and then loops back).
 This has implications on the route the packages may take! For example, localhost is allowed to use UNIX sockets, while 127.0.0.1 is not, this one must explicitly go through the network stack!
 The MariaDB server can see where a packet is coming from, and will differentiate between the two, so it is important to set up the one that the client actually uses.

 You seem to have done something unsual. There is no PHP7.2 in Debian's stable distribution. If you start upgrading packages manually you are doomed to manage your server security by yourself. Besides if you follow the web site you mentioned you are even installing files outside of the Debian package system. Pretty sure that's a bad idea on a public server.

A 'set' subclass providing fuzzy search based on N-grams.
The NGram class extends the Python 'set' class with efficient fuzzy search for members by means of an N-gram similarity measure. It also has static methods to compare a pair of strings.
The N-grams are character based not word-based, and the class does not implement a language model, merely searching for members by string similarity.
See the documentation, which includes a tutorial and release notes.
Use the GitHub issue tracker to report issues.
To install python-ngram from PyPI:
pip install ngram
How does it work?
The set stores arbitrary items, but for non-string items a key function (such as str) must be specified to provide a string represenation. The key function can also be used to normalise string items (e.g. lower-casing) prior to N-gram indexing.
To index a string it pads the string with a specified dummy character, then splits it into overlapping substrings of N (default N=3) characters in length and associates each N-gram to the items that use it.
To find items similar to a query string, it splits the query into N-grams, collects all items sharing at least one N-gram with the query, and ranks the items by score based on the ratio of shared to unshared N-grams between strings.
In 2007, Michel Albert (exhuma) wrote the python-ngram module based on Perl's String::Trigram module by Tarek Ahmed, and committed the code for 2.0.0b2 to a now-disused Sourceforge subversion repo.
Since late 2008, Graham Poulter has maintained python-ngram, initially refactoring it to build on the set class, and also adding features, documentation, tests, performance improvements and Python 3 support.
Development takes place on Github. On checking out the repo run tox to build the Sphinx documentation and run tests. Run pip install -e. to install the module in editable mode, inside a virtualenv.
