Description
The article gives results of research of the process of abrasive wear of samples made of Steel 45, U10 and with applied composite surface layer "nickelmulticomponent material with shape memory effect (SME) based on TiNi". For the tests we have chosen TiNiZr, which is in the martensite state and TiNiHfCu, which is in the austenitic state at the test temperature. The formation of the surface layer was carried out by high-speed gas-flame deposition in a protective atmosphere of argon. In the wear test, Al2O3 corundum powder was used as an abrasive. It is shown that the wear rate of samples with a composite surface layer of multicomponent materials with an SME is significantly reduced in comparison with the base, which is explained by reversible phase transformations of the surface layer with an SME. After carrying out the additional surface plastic deformation operation (SPD), the resistance of the laminated composition to abrasion wear is greatly enhanced, due to the reinforcing effect of the SPD. It is recommended for products working in conditions of abrasive wear and high temperatures to use the complex technology of formation of the surface composition "steel-nickel-material with high-temperature EPF", including preparation of the surface of the substrate and the deposited material, VGN in the protective atmosphere of argon, followed by SPD

Description
This article analyses the state religious policy in regard to the Russian Orthodox Church in the first post Great Patriotic War years. The characteristic of the religious life during the above-mentioned period in the Krasnodar Territory is given. The main resource of this research was documents of the Authorized Board on Russian Orthodox Church Affairs of the USSR Ministerial Council in Krasnodar Territory. Some positive changes in state- church relations took place. New churches began to open. Revitalization of the religious life came into being. It was shown in peoples’ participating in religious holidays, making orthodox ceremonies. Christening was the most popular ceremony. The less popular was the religious wedding. In that period of time, women were active participants of the religious life of the region. Among believers there were soldiers demobilized from the army. However from 1948 first signs of estrangement in state – church relations began to appear

01.00.00 Physical-mathematical sciences
DescriptionThe Euler function is very important in number theory and in Mathematics, however, the range of its values in the natural numbers has not been written off. The greatest value of the Euler function reaches on Prime numbers, furthermore, it is multiplicative. The value of the Euler function is closely associated with the values of the Moebius function and the function values of the sum of the divisors of the given natural number. The Euler function is linked with systems of public key encryption. The individual values of the Euler function behave irregularly because of the irregular distribution of primes in the natural numbers. This tract is illustrated in the article with charts; summatory function for the Euler function and its average value are more predictable. We prove the formula of Martinga and, based on it, we study the approximation accuracy of the average value of the Euler function with corresponding quadratic polynomial. There is a new feature associated with the average value of the Euler function and calculate intervals of its values. We also introduce the concept of density values of the Euler function and calculate its value on the interval of the natural numbers. It can be noted that the results of the behavior of the Euler function are followed by the results in the behavior of functions of sums of divisors of natural numbers and vice versa. We have also given the results of A.Z.Valfish and A.N.Saltykov on this subject

NEURAL NETWORK ALGORITHMS OF PATTERN RECOGNITION IN THE STOCK EXCHANGE RATE
DescriptionRecent research shows that patterns of stock market indices may contain useful information for the prediction of the stock market price. Currently, there are two basic pattern recognition algorithm: Match the rule and pattern matching. However, both algorithms require the participation of experts in the subject area. To solve these problems, the proposed approach is the recognition of patterns stock exchange indexes based on artificial neural networks. The experiment shows that the neural network is able to effectively study the characteristics of patterns and recognize them with high accuracy

PERFECTION OF CLEARING OF WATERS FROM PETROLEUM TECHNOLOGY
DescriptionNowadays there are sorbents, both natural, and modified, which allow to clear waters from variety of pollutants simultaneously, for example from ions of heavy metals and petroleum. We have received a new modified sorbent with use of a sol-method. The given sorbent represents beads in common besieged magnesium hydroxide and aluminum having layered structure. For the characteristic of the structure of the researched systems we have carried out an X-ray analysis. Studying the mechanism of interaction of the sorbent with ions of heavy metals was carried out with the use of the research of chemical structure of the sorbent and the condition of adsorbed ions by methods of IR spectroscopy and X-ray analysis. The conclusion was made, that modified inorganic sorbent on a basis of magnesium hydroxide and aluminum has a number of distinctive features and advantages comparing to other filtering materials

NEW SCIENTOMETRIC INDICATORS RESISTANT TO ARTIFICIAL “IMPROVEMENT”
DescriptionThe article presents the new criteria suitable for the diagnosis of the productivity of research and the importance of its results for the scientific community, are resistant to artificially "improve". It is known that generally accepted measure of the productivity of research scientists is the h-index, which is calculated based on a statistical method of scree. This indicator is applicable to research teams (organizations). However, the h-index and a number of other scientometric indicators based on citation, are easy to be artificially increased (fraudulent schemes action). New scientometric parameters adequately reflecting the importance of research results, and not amenable (or very difficult to) to be artificially "improved" are therefore needed; moreover, it is recognized around the world: the true score (not fictitious) of the significance of the results of a research scientist for the scientific community - is a complex metrological (scientometric) task. The authors argued that such indicators are primarily index latitude demand for research results, as well as a number of other parameters of copyright. Despite the fact that authors indicators, the same as the h-index are based on citation, their large values indicate that the scientific community recognizes the results of the research activities of scientific and pedagogical workers; moreover, these indicators can be considered as a criterion to identify really promising (productive) researchers. The problem of adequate assessment of the productivity of research activities and the significance of its results, the authors consider in the context of the problems (larger problems) of the effectiveness of educational environments. The practical significance of research results lies in the possibility of their use for constructing criteriondiagnostic apparatus for monitoring research activities of scientific institutions (including higher educational institutions). Research methodology: systemic, metasystemic, probabilistic-statistical and qualitative approaches. Research methods: cognitive, structural, functional, and mathematical modeling; methods of graph theory, sets and relations; system-cognitive analysis; methods of quality control (theory of latent variables); methods of probability theory and mathematical statistics (first of all – a method of scree), methods of analytical geometry; methods of the mathematical theory of limits

THE STUDY OF THE EFFECTS OF RICE QUALITY ON THE EFFICIENCY OF ITS PROCESSING
DescriptionThere were presented comparative analysis’ results of criteria rice quality used in Russian and international standards. Also there were shown summarized statistical analysis’ results of rice quality that was processed in 2013-2016 on rice mill plant at “Krasnodarzernoprodukt” Company. The purpose of research was to find factors that had influence on combining rice bulk effectiveness on specialized elevator. It was found that diapason of rice moisture content was quite small. Red rice content was ranging from 1.08 to 5.10 % with confidence interval of 1.98- 2.56 % that is evidence of small amounts of rice bulks with extreme high or low red rice content. Broken rice content varied in the wide range from 3.43 to 9.26 % with confidence interval from 5.84 to 7.26 % that shows necessity in length grading procedure applying for broken kernels removing at the elevator unit. Grain impurities content exceeded basic norm in 3-4 times that is a sign of low efficiency in the process of separation. During the treatment of rice bulks combined at the grain cleaning unit of rice plant broken rice cereals output varied in wide range from 3 to 9 % during single shift that is seems to be connected with kernels cracking increasing and rice moisture decreasing. Moreover, rice bran output also varied in a wide diapason from 10.2 to 17.0 % that could be explained by big swing in rice moisture, glassy texture and cracking of rice grains. According to our research it was investigated that current rice quality control system that is a base instrument of rice bulks forming for further processing is not quite efficient and as a result there should be created and implemented new methods and technical devices for quick and proper grain control that could assure stable technological regimes at different stages of rice treatment process and that would provide the best quality and the biggest output of rice cereals

PROSPECTS OF RECEIVING AND USING LIGHT WATER
DescriptionIt has long been known that mountain glacier water has special properties. It was found that such water contains fewer molecules with the heavy isotope of hydrogen - deuterium. On Earth, there are constant evaporation-condensation processes. The resulting protium water falls as rain. It is noted that the body of animals, as well as tropical fruits and vegetables containing water with an isotopic composition close to the composition of rainwater into these areas. When the nuclear industry began to produce heavy water, a byproduct of the production was the light water, which had a lower content of deuterium. Over a lifetime, a person drinks about 80 tons of water. As a result, the body receives 12-16 g deuterium and associated oxygen isotope 18O. This leads to damage to the genes, premature aging and the development of cancer. Numerous studies have identified a positive impact of light water on the growth of plants and living organisms. The biological effects of light water include the ability to optimize the biological reaction rate, the stimulation of cell division, radioprotective properties and antimutagenic effect. In Russia and abroad patented several methods and devices for producing light water, with severe medical and cosmetic properties. This water has become popular among the population. It has a higher value in comparison with typical drinking water. The article describes one of such units. In order to achieve its goals there occurs treatment of drinking water and low electromagnetic field is extremely low frequency. This plant is used to produce food protium water in the laboratory. It allows you to clean tap water from the deuterium content of tritium, salts and contaminants
