Шапочка для плавания малышей "Чебурашка"


Российская современная фундаментальная наука, а также офтальмология и психология научно обосновали древние знания о цветолечении. На этой основе были разработаны перфорационные очки-тренажеры с использованием нейтрального «зеленого» диапазона. Они усиливают работу одних фоторецепторов глаза и ослабляют работу других, улучшают качество изображения на сетчатке. Тем самым позволяют воспринимать тот же объем информации, но с гораздо меньшим зрительным напряжением.

Ultraviolet radiation (UV, UV, UV) - electromagnetic radiation, which occupies the range between the visible violet light and X-rays (380 - 10 nm, 7.9 1014 - 3.1016 Hz).

UV water treatment is needed to reduce the concentration of various pollutants and complete disinfection. Numerous studies have shown ultraviolet radiation is more effective than other agents for the destruction of chlorine.

Soon after it was discovered infrared radiation, the German physicist Johann Wilhelm Ritter began searching radiation and at the opposite end of the spectrum, with a wavelength shorter than violet tsveta.V 1801, he discovered that silver chloride decomposes when exposed to light, faster decomposed by invisible radiation beyond the violet region of the spectrum. White silver chloride in a few minutes it gets dark in the light. Different parts of the spectrum have different effects on the rate of browning. The fastest way is going to the violet region of the spectrum. Then, many scientists, including Ritter, agreed that light consists of three separate components: the oxidative or thermal (infrared) component, lighting component (visible light), and recovery (UV) component. While UV radiation also called actinic radiation. The idea of ??the unity of the three different parts of the spectrum were first made public only in 1842 in the writings of Alexander Becquerel, Macedonio Melloni, etc.

Ultraviolet water treatment

It should be noted that the sterilization of water does not completely remove residues. That is why it is advisable to install a water purification systems for more disinfectant. Sterilization of water is gaining popularity not only abroad but also in Russia, because it is economical, safe and effective.

Near ultraviolet, UV-A rays (UVA, 315-400 nm)
UV-B rays (UVB, 280-315 nm)
Far UV, UV-C rays (UVC, 100-280 nm)

Virtually all UVC and approximately 90% UVB is absorbed by ozone and water vapor, oxygen and carbon dioxide during the passage of sunlight through the atmosphere. UVA radiation from the range quite weakly absorbed by the atmosphere. Therefore, the radiation reaching the Earth's surface, to a large extent has near ultraviolet UVA and in a small proportion - UVB.

Eye Protection

To protect your eyes from the harmful effects of ultraviolet radiation using special goggles, detaining up to 100% of UV radiation and are transparent in the visible spectrum. As a rule, these glasses lenses are made of special plastic or polycarbonate. Many types of contact lenses also provide 100% protection from UV rays (note the labeling of packaging). Filters for ultraviolet rays are solid, liquid and gaseous. For example, ordinary glass is opaque at? 320 nm at shorter transparent only Special types of glass (up to 300-230 nm), quartz is transparent to 214 nm, fluorite - up to 120 nm. For even shorter wavelengths there is no suitable material for the transparency of the objective lens and has to use reflective optics - concave mirror. However, for such a short UV opaque and have air that significantly absorbs ultraviolet light from 180 nm.

In the ultraviolet radiation water treatment disastrous effect on the chain of ribonucleotides and DNA micro-organisms by disrupting their viability and ability to reproduce. In addition, ultraviolet radiation gives the permeability of cell walls and membranes of bacteria and helps to purify water from iron.

Lamp without bulb - a powerful source of ultraviolet radiation. During operation, a danger to the eye and skin.


Artificial sources

Thanks to the development and improvement of artificial sources of UV radiation that ran parallel to the development of electrical sources of visible light, now professionals working with UV radiation in medicine, prevention, sanitation and hygiene facilities, agriculture, etc., provided significantly greater opportunities than use of natural UV radiation. Development and production of UV lamps for installations photobiological action (UFBD) is currently engaged in a number of major companies and electrical lamp, etc.). Nomenclature UV lamps UFBD very wide and varied: for example, the world's leading manufacturer of Philips, it has more than 80 types. In contrast to the UV illumination light sources, as a rule, have a selective range, designed to achieve the maximum possible benefit for a specific FB process. Classification artificial UV AI application area, deterministic terms of the spectra of the respective FB processes with specific UV range of the spectrum

The design of the apparatus for the UV water treatment is very simple: in a metal reactor is UV lamp placed in a quartz tube, which serves to protect the lamp. In contrast to the flotation water uses complex physical-chemical method for the purification of water. Water flows around the lamp and disinfected. Depending on the contamination of water nutrients wattage and the number one reactor can vary significantly. Each has a different kind of bacteria resistant to ultraviolet water purification: the hardest destroyable with ultraviolet water purification spores and protozoa. But for this purpose use shungite filter.

In Central and Northern Europe as well as in Russia is widespread UV OC type "artificial sun deck, which uses UV LL causing fairly rapid formation of sunburn. In the spectrum of the "tanned" UV LL prevails "soft" radiation zone UVA UVB share strictly regulated, depending on the type of plant and the type of skin (in Europe are 4 types of human skin from the "Celtic" to "Mediterranean") and is 1-5% of the total UV radiation. LL Sun are available in standard and compact design with capacity from 15 to 160 W and a length of 30 to 180 cm in 1980, American psychiatrist Alfred Levy described the effect of the "winter blues" that now qualify as a disease and is abbreviated SAD (Seasonal Affective Disorder - Sezonozavisimoe disorder) disease is associated with poor insolation, that is natural light. According to experts, SAD syndrome confirmed by ~ 10-12% of the world's population, and above all the people of the Northern Hemisphere. Known data on the United States: New York - 17%, in Alaska - 28%, even in Florida - 4%. The countries of Northern Europe, data range from 10 to 40%.

Very rational application UFLL found, the emission spectrum which coincides with the spectrum of the phototaxis some species of flying insects (flies, mosquitoes, moths, etc.), which may carry diseases and infections that lead to spoilage and products. These LL UV lamps are used as attractants, in special devices, light traps installed in cafes, restaurants, the food industry, livestock and poultry farms, warehouses, clothing, etc.

If these conditions are not met, then we apply the filter you sovetum AG. Water purification system in such a way qualitatively and bstro can design our experts.

Degradation of polymers and dyes

Many polymers used in consumer goods, degrade under UV light. To prevent degradation of these polymers are added in special substances which absorb UV, which is especially important in cases where the product is exposed to direct sunlight. The problem manifests itself in the disappearance of color, dull surface cracking, and sometimes the complete destruction of the product. Degradation rate increases with increasing exposure time and intensity of sunlight.

The above effect is known as UV aging and is a type of polymer aging. For sensitive polymers include thermoplastics, such as polypropylene, polyethylene, polymethyl methacrylate (organic glass), and special fibers, such as aramid fibers. UV absorption leads to the destruction of the polymer chain and the loss of strength in a number of points of the structure. Effects of UV on polymers used in nanotechnology, transplantation, X-ray lithography and others fields for modification of properties (roughness, hydrophobicity) of the polymers. It is known for the smoothing effect of vacuum ultraviolet (VUV) to the surface of PMMA.

Experience of using ultraviolet light shows that if the installation is ensured not dose below a certain value, guaranteed lasting effect decontamination. In international practice, the requirements for the minimum dose range from 16 to 40 mJ/cm2. The minimum dose corresponding to Russian standards - 16 mJ/cm2.

"Compete" with the technology of ultraviolet water purification methods ozonation and chlorination of the competition is usually not kept as an ultraviolet water treatment has several advantages:

Qualitative chromatographic analysis of chromatograms obtained by TLC, often viewed in ultraviolet light, which allows the identification of a number of organic substances by the color of the glow, and retention indices.

Catching insects

UV radiation is often used when fishing for insects to light (often in conjunction with lamps that emit in the visible spectrum). This is due to the fact that most of the visible range of insects removed, compared to the human eye, in the short-wave part of the spectrum: the insects do not see that the person perceives as red, but they see the soft ultraviolet light.



Tanning and "Mountain Sun"

At certain dosages tanning improves the condition and appearance of human skin, promotes the formation of vitamin D. Currently popular fotarii, which is often called the home tanning beds.

Ultraviolet light in the restoration

One of the main tools the experts - ultraviolet, X-ray and infrared radiation. Ultraviolet rays can determine the aging varnish film - a fresh paint in the ultraviolet is darker. In light of the laboratory ultraviolet lamp darker spots appear the restored sites and handicraft copied signatures. X-rays are delayed more heavy elements. The human body is bone, and the picture - white. The basis of most of the white paint is lead, in the XIX century began to use zinc, and XX-m - titanium. All these heavy metals. In the end, the film, we get an image bleach underpainting. Underpainting - individual "signature" of the artist, the item its own unique technology. For the analysis of X-ray base underpainting used paintings of great masters. Also, these images are used to recognize the authenticity of the picture.
