USE A RADIATION PROTECTION CASE
For example, this memonizerSMARTWATCH case claims to help protect Apple Watch users from the negative effects of EMF radiation. However, be careful, there is a lack of data in terms of test results to prove the effectiveness of this product.
Since the smartwatch is worn directly on the body for a long period of time, electromagnetic fields and radiation are influenced through the symptoms above. By adding this extra protection (as well as reducing its use and wearing time), you put your health first.
DON'T BECOME ADDICTED TO YOUR WATCH
Most of us are probably a little guilty of depending on technology to help us connect with loved ones. However, if you feel like he controls you more than he helps you, it's time to disconnect.
If you can no longer be productive because your life is constantly filled with scrolling or games, then stopping using your watch for at least a while might be wise. Practice doing without it for a couple of hours, then a couple of days, then a couple of weeks in a row.
They say that three weeks without blemish officially breaks the habit! While it may seem like a waste of time not to carry the device you paid so much for, see it as an investment in your health. It's about knowing when you should use your watch and knowing when you should go without it.
FINAL THOUGHT
While the efficiency and convenience of smartwatches are abundant, there are a number of health risks that come with this type of technology. Due to the EMF radiation, it is not always wise to use your smartwatch in all situations.
Are you going to sleep? Going to a workshop? Dinner with your family? These are all situations in which you can do without your watch and you sleep better, have fewer headaches, improve your memory, be in a better mood, eat healthier foods, and be present with what you really need!
In 2020, the brand went on an independent "voyage", focusing on its own phones. Recently, smartphone users were shown three new items at once - Honor 50 (basic), Honor 50 Pro (large) and Honor 50 SE (budget). Each smartphone of the family is equipped with displays with a refresh rate of 120 Hz, a sampling rate of the sensor layer of 300 Hz.
New items differ in screen sizes. The Honor 50 has a 6.57-inch OLED monitor, the 50 Pro has a 6.72-inch display with the same matrix, the Honor 50 SE uses a 6.78-inch IPS panel. The first two models are bent on the sides, each smartphone has a screen resolution corresponding to the Full HD + class.
The rear cameras of the Honor 50 and 50 Pro have main sensors with a resolution of 100 megapixels. In addition, there are additions to 8 Mp and 2 Mp sensor units. These models are powered by the Qualcomm Snapdragon 778G chipset.
The Honor 50 SE (internal storage can be 128 or 256 GB, as in the basic configuration) has a 108 megapixel main sensor, which is complemented by auxiliary sensors of 8 and 2 megapixels. The phone is equipped with MediaTek Dimensity 900. Theblocks of the main cameras for each model are made in the form of two rings (own brand design). The front camera of the Honor 50 Pro (permanent memory is 256 GB) is located in the oblong cutout of the display panel and combines two blocks of 12 megapixels and 32 megapixels (sensors).
For all these reasons (and more), EMF emission and smartwatches are interactions that need to be known and aware of. Reduce your use and use a cover that helps protect your body. All this extra work will improve your health! The Honor 50 and 50 SE offer two 32MP and 16MP front sensors, respectively.
Smartphones also differ in the amount of "RAM": the basic version and the advanced version are available in versions for 8 and 12 GB, the budget version - in 6 and 8 GB.
The devices are equipped with Android 11 OS, equipped with a proprietary Magic UI shell, and Google services .
The smartphones run on different batteries: the Honor 50 Pro and 50 SE have a 4000 mAh battery, and the base model has a 4300 mAh battery. The advanced versions of Honor are equipped with 100W fast charging, while the more affordable smartphone is equipped with 66W.
It is possible to become the owner of new products from the brand by pre-order from the PRC, phones will appear in the USA and Europe later.

Large two-way flows of mobile students in higher education are as follows: China with us, India in the USA, China Japan, South Korea, China, Australia, China, UK, China, South Korea, China, Canada, India, UK, Canada, USA , Japan, USA, Turkey, Germany, Morocco and France. The importance of China as a major market of origin and the United States as a major destination is very evident from these flows. There may be other important bilateral flows (through TNE, student exchanges and short-term mobility) that are not listed here - for example, inflows to China, Singapore, Malaysia and other countries.
Over the past decade, student Chinese outflows to the United States, Australia, Japan, South Korea, Canada and the United Kingdom have taken the leading positions in the standings for the fastest growing, in absolute terms. There are also some interesting falls just like in novels in bilateral student flows: Japan to the US, Greece, UK, Singapore, Australia, China, Malaysia, Indonesia, Malaysia, and Indonesia to the US.
As previously demonstrated, two-way trade patterns are an important factor in two-way mobile university students of origin, assignment patterns, both in the history and forecasting methodology used to make forecasts until 2020. Due to the lack of comprehensive bilateral trade services data, this global analysis is based solely on bilateral trade in goods. Although at the UK level, where bilateral data services are provided, some seem to be the relationship between bilateral trade services and the student's country of origin. This communication is of particular importance to the following countries: Canada, Japan, China, South Korea, India, and Switzerland. Some countries, however, match less this ratio, such as Malaysia, Nigeria, Hong Kong and Indonesia.
The UK typically has a share of outbound mobile students from certain origin markets - India, Nigeria, Malaysia, Hong Kong, Sri Lanka, Ireland, and the UAE - which far exceed its share of bilateral trade with these countries. This demonstrates the importance of historical novel and cultural ties and language in explaining two-way student flows mobile.
Transnational Education (TNE)
Definition of TNE
One of the definitions of TNE delivers education where the students are located in a country other than the one where the chosen institution is based. 4 The
Global TNE Alliance is specifically designated as an export product. There are many ways in which learning is delivered transnationally, including through distance education (with or without local support), joint programs, articulation programs, affiliates, and franchise agreements.
TNE is attractive for students wishing to obtain a foreign qualification without leaving the country of residence. It can also be attractive to employers and governments are considering human resource development options, including multinational or global corporations with a geographically dispersed workforce. Education providers are looking for ways to expand their export markets, attracted by the opportunities of transnational education. In other words, TNE can be mutually beneficial to all stakeholders - students, higher education providers, and host governments and countries - if it is implemented effectively.
There are very different policies in different countries to support and promote TNE, both in terms of outgoing domestic students and incoming foreign students. They can be opaque, conflicting, and sometimes a source of considerable frustration. India, for example, has so far failed to provide clear guidance on what development of education and cooperation will and will not allow.
In China, the government often requires overseas institutions to enter into partnerships with local suppliers, policies aimed at protecting and improving quality standards in the domestic education market. In addition, other countries such as Brazil and Indonesia have legislative frameworks that have not yet been proven to facilitate TNE initiatives from overseas suppliers.

If the packaging indicates that the watercolor paper contains 99% or less cotton, it is considered blended. Cellulose paper with the addition of cotton belongs to the same category. Often bamboo, rice, flax are added to wood fibers (cellulose). The most common formulations of mixed watercolor paper are cotton + cellulose and cotton + bamboo.
Depending on the percentage of fibers, the properties of watercolor paper will be different - here it is important to determine what is important specifically for the artist himself, what effects and qualities of watercolor painting are in priority, which is especially important in the process of conducting watercolor work. You can shift priorities towards more or less cotton fibers in the composition.
Mixed watercolor paper is perfect for teaching watercolor painting, for working on long-term sketches of a large format, for layered glaze painting with watercolors. Combining the basic properties of pure cotton and cellulose paper, watercolor paper of a mixed composition allows you to fully control the process of writing an etude, control the properties of pigments and the amount of water, quickly make changes or dry the desired areas.
The density of paper for watercolor is in the range of 170 g / m2. up to 850 g / m2 The standard density, which is suitable for most tasks, is 200-300 g / m2. It is easy to distinguish watercolor paper by density & brush, focusing on its thickness and weight - the heavier and thicker the paper, the denser it is, which means it will be less deformed and better retain water during drawing. Thin watercolor paper should be stretched over the base so that it does not warp, creating random accumulations of paint and other textures (I will talk about this in the next article).
It is especially important to stretch watercolor paper if you plan a large and long-term (many hours or multi-session) watercolor work.
The choice of paper with a high density is not always justified: for sketching or quick sketches, a paper density of 170-200 g / m2 is quite enough, for educational work in watercolor - 250-300 g / m2, for complex author's compositions in watercolor - more dense 300 g / m2 and higher.
It is not recommended to fold sheets of thick watercolor paper (and it’s just technically difficult to do it), so students of art schools and student artists who prefer a tube to a folder write on thin watercolor paper. By the way, the price of watercolor paper rises along with the increase in density - another argument for beginners not to chase the best materials, but to choose a reasonable ratio of price and quality.

Work gloves are personal protective equipment, their main function is to protect hands from possible injuries, negative effects of harmful substances, dust, dirt. Everyone needs gloves: they are used by builders, movers, auto mechanics, gardeners, cleaners. Each of us uses them in everyday life. Now the assortment of gloves in hardware stores is huge. Gloves are universal and special, for different weather conditions, different in the level of protection. How to make the right choice with such a variety? The main thing when choosing gloves is to take into account the specifics of the work ahead. Below we will look at the materials that are used to make gloves.
Cotton
Cotton is the basis for knitted gloves. This material allows air to pass through well, without creating a "greenhouse" effect. Cotton gloves are comfortable, do not hinder movement, they retain the sensitivity of the fingers. They are versatile gloves, they do not have increased protective properties, but they are absolutely necessary to protect your hands from dirt, minor injuries and injuries. These gloves are easy to get dirty and can be washed and reused.
Knitted cotton gloves are of different density, which determines the number of threads (usually four, five or six threads) and knitting class, these indicators affect the strength and durability of the gloves and brush. The most popular type of cotton gloves is knitted with a PVC dot applied to the inside of the glove. PVC dots provide additional wear protection and provide a secure grip on tools. The price of such gloves depends on the density of the knit and the quality of the edge processing.
To give the cotton fabric additional protective properties, in the production of specialized gloves, cotton is sprayed or impregnated with other materials.
Latex
In the manufacture of latex gloves, an aqueous dispersion of rubber is used, which is vulcanized into rubber. Latex-doused gloves provide a secure grip, protect hands well from mechanical damage, are convenient to use, are highly wear-resistant, and get less dirty.
Nitrile
Nitrile coating provides reliable protection against chemicals, has puncture, tear, cut resistance. Nitrile gloves are suitable for working with greasy and abrasive materials, oil products, acid and alkaline compounds, solvents, varnishes. Such gloves are used in laboratories, in the food industry, and in medicine.
Neoprene
Neoprene gloves are comfortable to work with for a long time. Such gloves do not get wet, retain elasticity at low temperatures and tensile strength. Neoprene gloves are suitable for working with chemicals, paints and varnishes, during general construction work. The inner cotton cover will protect your hands from irritation and allergic reactions.
Vinyl
Vinyl gloves are cheaper than nitrile and neoprene gloves. Vinyl is resistant to alkalis, acids, alcohol. Such gloves do not reduce sensitivity, they are air permeable, have a fairly high tear resistance and provide a reliable, slip-free grip of objects.
Split
Split leather gloves and gaiters will protect your hands from punctures, cuts, hot metal sparks and other mechanical influences. It will be comfortable to work in split leather gloves, this is a natural material, it allows air to pass through well, but will not tolerate water. The main property of this material is resistance to high temperatures.
During repairs, for dry work, ordinary, universal cotton gloves are suitable for you. For working with aggressive agents, when interacting with water, choose gloves made of neoprene, nitrile or latex. When performing electrical work, vapors with a protective coating of rubber or latex are needed, such gloves do not pass current and will provide the necessary level of safety. For work at high temperatures, use heat-resistant gloves. In the cold season, insulated models should be used

This is a watch with a quartz crystal as an oscillating system. They can be electro-mechanical with a pointer time indication and electronic with digital indication.
How a quartz watch works
The principle of operation is based on the chemical properties of quartz. This mineral is piezoelectric: under the influence of electricity in clock circuits, it vibrates (vibrates) with a frequency of 32,768 times per second. The microcircuit counts the number of vibrations and uses them to generate regular electrical impulses once a second. The pulses are fed to the liquid crystal display of an electronic clock or control the stepping motor of the clock circuit, converting electrical energy into mechanical energy. Further, the rotational movement is transferred to the wheel mechanism, and its gears set the clock hands in motion.
The power source in a quartz watch is a battery. The wrist models use a button battery.
What does a quartz watch look like?
1 - Battery
2 - Quartz generator block
3 - Stepper motor
4 - Wheel mechanism
In order for the quartz to vibrate at the desired frequency under the action of the current, a U-shaped crystal of a certain size is placed in the circuits. The number of fluctuations is not a random number. If you use a 15-bit binary counter and apply a frequency of 32,768 oscillations to it, this is the number that will give a time interval of 1 second. A large number of bits of binary code is impractical from the point of view of resource allocation.
A Few Facts About Quartz Watches
The first wrist quartz watch was released by the Japanese company Seiko in 1969.
Quartz crystal watches are quite accurate - they lag behind or go ahead by no more than 20 seconds per month.
They don't need to be turned on every day. It is sufficient to check the accuracy once a year.
Quartz wears out over time and the watch wears out. But the degradation of the crystal takes several decades - there are no exact figures yet. All wearing parts can be replaced.

Counterfeits are everywhere now and they affect all products presented on the market including watches. A counterfeit watch is difficult to recognize when choosing one that is new or little known to us, but by noticing the small details you can easily distinguish them from real quality watches. First of all you must know that to have any reliable product you must avoid black markets and unrecognized and unreliable sales sites, and again you must beware of extraordinarily low prices. The finishes of the counterfeits are generally very poorly done whether in the dial or the back of the case and even the bracelet and the clasp. Its components are also of very poor quality, you can notice it by the weight of the case which is too light or too heavy, you can also suddenly move the case to notice if its components are well fixed. You can also distinguish a counterfeit from the original by the name of the brand which is not known as you can find symbols of a quality brand with small modifications. So pay close attention to the little details that make all the difference.
Are quartz watches reliable?
The quartz watch has been around for years now, it is known for its originality and the reliability of its operation. It is the improved version of automatic watches since it was able to improve precision and reduce the deviation or time difference as much as possible. During its years the watchmaking experts were able to further improve the quartz watch while keeping the classic model, they perfected its operating system and they also reduced the size of the case and used more solid and scratch resistant materials and at the water. So it is possible to wear the watch everywhere and use it in different places without fear.
Why choose a quartz watch?
Quartz watches are still worn today, generally by hardworking people and important in their fields since this watch is a sign of punctuality, originality, strength and charisma so to have it all at the same time you will need a watch that will complete your look. What makes quartz watches more original is their operation which uses one of the most important phenomena of physics which is piezoelectricity, which allows perfect precision, but also the chronograph function that no other watch has. analog display only used before. With all the quartz watch models presented on the market right now, it is easy to find the one that suits our everyday look but also our personal tastes.

School uniforms are the subject of much debate in US state school systems. Both sides have good arguments as to why schools should or should not require them from students, and the uniforms have grown in popularity in recent years.
Summary of this practical sheet
1 Definition
2 Statistics
3 Cost
4 Benefits
5 Disadvantages
Definition
School uniforms are specific clothing that a certain school requires its students to wear. Uniforms usually consist of a shirt or polo shirt for boys and girls and dark or brown pants for both or a dark or plaid skirt for girls. The shoes can be dress shoes or dark shoes.
Statistics
As of 2009, in the United States, there are 21 states whose public school system requires students to wear uniforms. A 1999 case study in Long Beach, California found that adopting a uniform policy significantly reduced violence and other problems in schools. Crimes, suspensions and sexual offenses have all been reduced by at least 90% and vandalism has fallen by almost 70%.
Cost
The cost of uniforms is a concern for some families, but families in which children wear uniforms have been shown to spend almost $ 80 less on their children's clothing for the school year compared to those who do. do not have children in uniform. In addition, 44% of families in which children wear uniform believe that it allows children to focus more on school.
Benefits
Some of the benefits of school uniforms include less violence in schools and increased student discipline. Violence decreases because students are less likely to be harassed for their clothes because it is not possible to emphasize brand names. Additionally, students from poor families are less likely to feel jealous or ashamed of not wearing the same clothes as students from richer families. Also, since children wear the same things, it is difficult, if not impossible, for them to wear gang colors or other types of gang related items.
Disadvantages
In the debate against uniforms, there are several points that are often mentioned. First of all, uniforms don't necessarily end bullying or other forms of violence. While the same clothes can help even out appearance, this will not prevent some students from finding other reasons to distinguish people. Additionally, forcing students to wear uniforms can stifle personal expression and creativity. This expression is part of personal growth and it is very important that children can express themselves and become an individual. Additionally, some students may resent being forced to wear uniforms, prompting them to take action.
