RESTRICTED MANY-BODY PROBLEM IN THE RICCI FLOWS IN GENERAL RELATIVITY
01.00.00 Physical-mathematical sciences
DescriptionIn this article, the restricted problem of three and more bodies in the Ricci flow in the general theory of relativity considered. A system of non-linear parabolic equations describing the evolution of the axially symmetric metrics in the Ricci flow proposed. A model describing the motion of particles in the Ricci flow derived. It is shown that the theory describing the Ricci flow in the many-body problem is consistent with the Einstein-Infeld theory, which describes the dynamics of the material particles provided by the singularities of the gravitational field. As an example, consider the metric having axial symmetry and contains two singularities simulating particles of finite mass. It is shown that the static metric with two singularities corresponds to Newton's theory of the two centers of gravity, moving around the center of mass in circular orbits in a noninertial frame of reference, rotating with a period of bodies. We consider the statement of the problem of many bodies distributed at the initial time on the axis of symmetry of the system. 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 axis of the system. This is achieved due to relativistic effects, which have no analogues in Newton's theory of gravitation. Using the properties of relativistic potentials we have justified transition from the relativistic motion of the particles to the dynamic equations in the classic theory

ASSESSMENT OF MILITARY AND PROFESSIONAL ADAPTATION OF CONSCRIPTS
DescriptionThe article presents a methodology of assessment of military and professional adaptation of conscripts considering a 12 month length service. This methodology intended to be used by officers (supervisors) at work with staff to monitor the dynamics, diagnostics and forecasting of the military personnel adaptation process and the adoption of corrective and management solutions. It includes criteria for testing and monitoring the daily activities, which are integrated with common methodological positions into the adaptation process of an assessment system. Developed methodology of military and professional adaptation assessment lead to necessity to develop certain types of conscript’s adaptive behavior. To make this methodology more effective in implementation, there was developed software, which allows receiving recommendations by command staff for the management of the adaptation process of each soldier after initial data entering. The developed software is aimed to be used by command staff for improvement of the effectiveness of subordinate personnel and does not require a special training

Description
Small businesses play a special role in the development of the state economy: the national budget from taxes, increasing the welfare of the population, the question of employment, the formation of competitive environment, cost containment and improving the quality of goods and services. In this regard, become topical issues related to the creation of favorable conditions for the functioning and development of management tools and mechanisms of development of organizations of this segment of the economy. This work aims to identify the key problems of functioning of small business organizations through the assessment of the development of this segment in the economy of the Krasnodar region. For the evaluation of small business development in the Krasnodar region we used basic unit of economic analysis aimed at determining the major trends of change in number of organizations average number of employees, revenues, as well as a number of relative indicators in the whole segment and by major activities. It was determined that the number of small businesses in the Krasnodar region for three years practically did not change, whereas a decrease in the number of workers employed in this segment, revenue has a small tendency to increase. In the structure of the segment is dominated by micro-enterprises, 47% operate in the trade sector. Indicators of development of small business organizations meet the classification criteria in terms of revenue for microenterprises and their share in total number of companies this segment is 1%. The results of the study say the lack of a clear strategy from small businesses, due to unavailability of tools for its development, expressed the high value of the resource and, as a consequence, ignoring this question when organizing the activities of enterprises. Therefore, the question becomes more urgent the development of tools of business modeling and strategic planning adapted to the requirements of this segment

DescriptionThe experiments were conducted on bull-calf of Kazakh white breed at the age of 12 months. In the capacity of feed additives there were used "Yoddar-Zn", which consists of microelements as iodine and zinc in organic form, and the additive "Glimalask-Vet" based on organic acids (I gr.). A second group of animals received only a basic diet with "Yoddar-Zn» (II gr.) feed additives. In the organism of experimental groups of calves, the transformation proceeded more intensively for nutrient feed. This has contributed to increase the intensity of their growth, slaughter performance and the quality of the resulting beef. Bulls that received a ration feed additives had a live weight more on 35,9, and 20,4 kg, carcass weight after slaughter - at 22,27 and 11,47 kg, and the mass of flesh - at 20,9 and 8,50 kg., compared with the control. The average sample flesh of carcass fat content was higher by 1,25 and 0,74%, protein – 0,68 and 0,47%, iodine - at 39,30 and 26,71%. The animals of experimental groups in the edible portion of the carcass was synthesized as compared to control, more protein on 5,86 and 10,71% and energy - on 10,95 and 5,02%. The highest efficiency established at complex using both feed additives. Estimation of economic efficiency of use of these feed additives showed a decrease in cost and increase in profitability of beef production

PERSPECTIVE TECHNOLOGIES OF POSTHARVEST SUNFLOWER SEED PROCESSING
DescriptionThe designers of competitive seed-cleaning equipment face a crucial task to develop a rational technology of post-harvest seed processing, which would provide output of high quality certified seeds with minimal cost. For determining rational technology of post-harvest processing of sunflower seeds in the seed-cleaning machine based on the grain-cleaning unit ‘GCA-20’, we chose three existing technologies (without fractionation), with various combinations of grain-cleaning equipment, one fractional technology followed by separation of seeds into size fractions (Ø7-Ø8 mm, Ø8-Ø9 mm) on the photoelectron separator. The aim of the study was to determine the priorities of the promising option of post harvest processing by the method of priori ranking using a psychological experiment. According to the survey results, we calculated the coefficient of concordance. After the calculation of the coefficient of concordance its significance was determined using Pearson criterion with the number of degrees of freedom equal 4. The calculated value of Pearson criterion is 17.58, and the table value is 9,488. As the table value is less than the calculated value of Pearson's, we can argue with 95% probability that the opinions of the experts regarding the priority technologies are assessed by the coefficient of concordance and the consistency of the researchers is not accidental. After checking the coefficient of concordance on Pearson criterion a chart of ranking options was built. As a result of the psychological experiment there was determined the rational variant of the technology of post-harvest sunflower seed processing. According to this technology seeds need to be fractioned into two size fractions (Ø7–Ø8 mm, Ø8–Ø9 mm) on the photoelectron separator at the final stage of seed separation in seed-cleaning complexes. This technology will allow us to increase the output of high-quality seeds and reduce their content in the waste (85.52 to 65.60%)
