MANY-BODY PROBLEM IN THE METRIC OF CIRCULAR DISTRIBUTED SOURSES
01.00.00 Physical-mathematical sciences
Description
In this article we consider the many-body problem in general relativity in the case of the distribution of N singularities on the circle. It specifies the exact solution of the problem for an arbitrary distribution of singularities. It is shown that the static metric of N singularities corresponds to Newton's theory of N centers of gravity, moving around the central body in a circular orbit in a non-inertial frame of reference, rotating with a period of bodies revolving. We consider the statement of the problem of many bodies distributed at the initial time on the circle. In numerical calculations, we studied the properties of the gravitational potential in the problem of establishing a static condition in which multiple singularities retain the initial position on the circle. This is achieved due to relativistic effects, which have no analogues in Newton's theory of gravitation. Using the properties of relativistic potentials justified transition from the relativistic motion of the particles to the dynamic equations in the classical theory. A system of non-linear parabolic equations describing the evolution of the metric in the Ricci flow proposed. The problem of the calculation of the potentials in the Ricci flow formulated. The application of the theory to describe the ring galaxy, planetary rings and the asteroid belt considered

Description
The creation of artificial intelligence systems is one of important and perspective directions of development of modern information technology. Since there are many alternatives of mathematical models of systems of artificial intelligence, there is a need to assess the quality of these models, which requires their comparison. To achieve this goal we require free access to the source data and methodology, which allows to convert these data into a form needed for processing in artificial intelligence. A good choice for these purposes is a database of test problems for systems of artificial intelligence of repository of UCI. In this work we used the database "Iris Data Set" from the bank's original task of artificial intelligence – UCI repository, which solved the problem of formalization of the subject area (development of classification and descriptive dials and graduations and the encoding of the source data, resulting training sample, essentially representing a normalized source data), synthesis and verification statistical and system-cognitive models of the subject area, identify colors with classes, which serve varieties of Iris, as well as studies of the subject area by studying its model. To solve these problems we used the automated system-cognitive analysis (ASC-analysis) and its programmatic Toolkit – intellectual system called "Eidos"

STUDY OF SOIL WATER REGIME ON VINEYARDS OF ANAPA - TAMAN SUBZONE
06.00.00 Agricultural sciences
Description
One of the limiting factors to obtain high yields of grape plantations in Anapa-Taman subzones with good quality is moisture. Grape plant adapts well to a limited amount of moisture in the soil. The penetration of roots deep into the soil horizons may reach 5-6 meters, provided with a moderate density of the soil and the lack of limiting factors such as the presence of ground water and limiting the content of toxic soluble salts. In the course of mathematical data processing we have established a trend of increasing average annual rate of precipitation in the period from 1932 to 2015. In the years when the amount of precipitation for the year exceeds the average long-term performance, the key amount of precipitation in the summer months in a downpour and in a limited area. Average annual amount of precipitation in the period from 1932 to 2015 was 519 mm, the minimum was recorded in 2002 (324 mm), the maximum - in 1981 (800 mm). Despite the general trend of increasing average annual rainfall over the years, moisture deficit is in the soil. Accounting of moisture saving dynamics in the soil in the 2015-2016's indicates the absence of moisture reserves. Optimal soil moisture values were observed only in May and June, and only half meter layer of soil. In the phase of growth and ripening berries (July, August, September) soil moisture content was much lower than the permissible value, which is comparable with the level of wilting point. For the stable-quality grape raw materials it is necessary to pay more attention to the water and the air regime of the soil

EXPLORING THE POSSIBILITY OF OBTAINING PECTIN EXTRACTS OF HIGH PURITY
Description
The article describes a possibility of obtaining food pectin extracts of high purity form secondary raw materials such as sunflower anthodiа. The relevance of the use of pectin extracts as independent products or as an ingredient in food products for therapeutic and prophylactic purposes is determined by the high complexing ability of pectin substances in the dissolved form, in comparison with the commercial powder pectin. The use of pectin extracts reduces the cost of the final product by reducing the number of technological procedures. As dried plant material is mainly used for the production of pectin and pectin extracts, the article presents the study of the swelling process of dried and crushed sunflower anthodiа. It is established that the inclusion of the swelling process as a separate technological process for the production of pectin extract from the sunflower anthodiа is impracticable. The study on further processing of vegetable raw materials by electroactivated water system (EAWS) to reduce the content of ballast substances in raw material in relation to pectin and increase the purity of pectin extract is also presented. Some processing options of sunflower anthodia with EAWS of various рН were considered as well. The decrease in the content of dry substances in the processing of plant material that characterizes the decrease in the number of ballast substances is shown. We have also calculated the purity of the obtained pectin extracts

INVESTMENT POLICY OF CHINA AS THE DIRECTION FOR IMPROVEMENT OF THE RUSSIAN INVESTMENT CLIMATE
Description
In the article the investment policy pursued in China, defining high rates of economic growth and social changes in the country is considered. It is proved that the investment policy of China was directed to inflow of volumes of foreign investments which create benefit for export growth, modernization of technologies and skills, without negative consequences. As on the volume of foreign investments China takes the leading positions, the main reasons for appeal of this country for foreign investors are considered. Dynamics of volume changes of foreign investments of China is traced, changes of volumes of the Russian investments into the Chinese economy are compared. Positive and negative sides of investment policy of China are shown. In the article three key sectors of economy in China in which foreign investments are encouraged are described. The first sector of economy will promote increase in export subsequently. The second sector is earlier limited or closed sectors of economy, investments into which began to be encouraged since 2005 in connection with the entry of China into the WTO. And as the last key sector of the economy in China expensive energy, infrastructure and ecological projects are selected. Primary branches of the Russian-Chinese bilateral investment cooperation are considered. The examples for improvement of the investment policy of Russia followed from experience of investment policy of China are given

Description
Occupation of the Soviet territory by German fascist invaders during the Great Patriotic War caused considerable damage. The Soviet Government developed legal and regulatory framework for the methods of assessment of damage. The purpose of this article is to analyze the legal framework, by the example of a regulatory act according to which calculation of damage to the collective farms in the occupied territories during World War II was made. The NKVD instruction "On the procedure of collecting, recording and storage of documentary materials relating to the atrocities, destruction, looting and violence of the German authorities in the occupied Soviet areas" was adopted in May 1942. Based on the instruction, and under orders of the NKVD in Elista, events to identify and collect materials that characterize the crimes of Hitler's government were carried out. According to these instructions, materials reflecting Nazi atrocities were subjected to the mandatory deposit of the State Archives. The paper gives summary quantitative data on the results of assessment of damage caused during the occupation period in August 8, 1942 to January 20, 1943

IRONIC DISCOURSE IN "NOTEBOOKS" BY A. VAMPILOV
10.00.00 Philological sciences
Description
The article analyzes "Notebooks" by one of the most prominent playwrights of the 20th century Aleksandr Vampilov. "Notebooks" are considered as an example of ironic discourse in this genre. The study of irony nature in Vampilov’s “Notebooks” reveals the patterns of ironic discourse, which manifest themselves in the ironic light of serious domestic, moral, and professional problems. We perceive it today as intellectual and moral impetus, a special mood allowing us to survive, as self-protection of the individual from the pressure of reality. The irony in Vampilov’s "Notebooks" is achieved by the desire of getting away from the stereotypes of consciousness, obsolete dogmas. The irony "disallows" the eternal oppositions "new—old", "temporary—eternal", "subjective—objective", "art— life". The ironic game with terms, cliché expressions, denoting compromised political and ideological phenomena, with the concept of a name; the ironic interpretation of moon image as a leitmotif in Vampilov’s work reflect dominant ironic pathos of notebooks. The analysis of “Notebooks” by A. Vampilov allows us to understand the irony not only as a consequence of painful antinomicity, personal spiritual contradictions inherent to the artist of that time, but as a way of world vision: the ability to overcome the deadlock of crisis period, and aspiration of the creative personality to the desired integrity

USE OF EPIN-EXTRA, R PREPARATION ON SEED PLANTS OF ONION
Description
An important element in the technology of growing seed plants of onion is the use of physiologically active substances to protect plants from frost in early spring growing season. Damage to plants during this period affects seed production. In the experiment we used preparation called Epin-Extra R, with which the leaves of plants were treated a day before expected frost. Test results have shown high efficiency of preparation in the field and in the film unheated greenhouse. Treatment helps to balance the negative impact of low temperatures and obtain an additional seeds yield 92-95 kg / ha more compared with the control, due to the increase of seed of productivity of plants to 3.2 g
