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

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

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

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

Description
In the article, we have performed an analysis of respect for the principle of immunity of the right of a private property in case of the address of a claim to property. Restrictions of the principle of immunity are shown concerning both property objects, and concerning competences of the owner that in case of proper approach from the legislator is not violation of the rights and interests of the person. The unique premises can act as a subject of the address of collection of debts of the testator. It is established that the size of the money which isn't subject to collection shall be determined living at least by the territorial subject of the Russian Federation, and also funds for expenses for acquisition of necessary medicines and the equipment shall be in addition guaranteed. Shortcomings and contradictions in case of regulation of the bases of the address of collection on separate types of property are revealed, suggestions for improvement of these provisions are made

JUSTIFICATION OF SUNFLOWER SEED CLEANING SCHEME ON AIR-SIEVE GRAIN CLEANING MACHINES
DescriptionA set of actions aimed at preserving seed quality is the task of primary importance, which is expected to produce effective results. To implement this task it is necessary to prepare high-quality seeds by cleaning and sorting sunflower seeds on air-sieve grain cleaning machines. To determine the rational scheme of cleaning sunflower seed piles of the ‘Lakomka’ variety on the air-sieve grain cleaning machine ‘MVU-1500’ a qualitative analysis has been carried out. Cleaning sunflower seeds is carried out by an air stream by one or two sieves for separating large impurities and by two sieves, one of which separates milled seeds into the overseeding ,with the second dividing the whole seeds. In such a scheme of cleaning sunflower seeds, purity corresponds to the 3rd class of seed material and has some disadvantages. The disadvantages are as follows: the gathering seeds in sieve Ø5.0 have low individual weight and the sieves show low quality of work. To facilitate the work of the sowing sieves a grading sieve is installed, which will separate 50% of the seeds into the gathering. The size of the openings in the grading sieve is selected with the help of the correlation table. The sieve for sunflower seed variety ‘Lakomka ‘will be Ø 3.6, which will select the most valuable seeds with weight above 90 g from the purified material thus improving the productivity and performance of the sowing sieves. A promising scheme of cleaning sunflower seeds is the air flow rate equal to 4.43 m/s, with one grading sieve of Ø 3.6 and two sieves of Ø 7 and Ø 3.6 mm in grain cleaning machines that will allow you to get high quality seed material that meets the requirements of GOST(Russian national standard) for seed material

THE RATIONALE FOR SELECTING THE METHOD OF FORECASTING THE DEVELOPMENT OF A DIVERSIFIED CORPORATION
DescriptionApplication of classical forecasting methods applied to a diversified corporation faces some certain difficulties, due to its economic nature. Unlike other businesses, diversified corporations are characterized by multidimensional arrays of data with a high degree of distortion and fragmentation of the information due to the cumulative effect of the incompleteness and distortion of accounting information from its enterprises. Under these conditions, the applied methods and tools must have high resolution and to work effectively with large databases with incomplete information, to ensure correct common comparable quantitative processing of the heterogeneous nature of the factors measured in different units. It is therefore necessary to select or develop some methods that can work with poorly formalized complex tasks. This fact substantiates the relevance of the problem of developing models, methods and tools for solving the problem of forecasting the development of diversified corporations. This article compares methods of forecasting and encourages using the ask analysis which has a good theoretical justification for the meaningful interpretation of a knowledge model based on information theory; high accuracy and independence of calculation results of the unit of measurement baseline data through the use of not the correlation matrix, as in statistical systems, and matrices of knowledge. A well-developed and available Toolkit of the ASK-analysis which is an intellectual system called "Eidos" (created by E. V. Lutsenko, 1994) allows, on the basis of fragmented, noisy source data of various nature (numeric, text) to create models of large dimension. The ASK-analysis and the system of "Eidos" have been widely and successfully used in economics, engineering, agriculture, sociology and other fields. These features of the ASK-analysis have led to the fact that it was chosen as the method of forecasting of dynamics of indicators of the corporation

Description
To increase the validity of conclusions about the impact of the environment on the quality of life we need to move from generalities to the application of quantitative modeling techniques. This requires the joint processing environmental databases and databases depicting various aspects of quality of life. These databases are needed to be handled not just together, but in a comparable form approach, including technology and methodology, and to be implemented in one software system. For the first time in the environmental studies, it has been planned to be done with the application of the ASK-analysis and the system called "Eidos". Previously, the authors have set the goals and the objectives of the application of the ASK-analysis to study the effect of environmental factors on the quality of life of the population of the region. The article reveals the urgency of this study; the requirements for the method of conducting the study, the choice of a research method; as well as the contents of the objectives of the study. The proposed work is at the edge of mathematical ecology and mathematical modeling of quality of life (which refers to mathematical and instrumental methods of Economics), resulting from expected synergies, consists in obtaining of new knowledge in these fields that is relevant to both ecology and economy. This knowledge will make it more meaningful and justified for the application of environmental criteria and concepts in the economy. This work contains a description of the basic data sources for the study of the impact of environmental factors on various aspects of quality of life of the region's population, the source data for this study, the characteristics of the original data, substantiation of requirements to the method of research, choosing research methods appropriate to requirements; the development of steps to achieve the objectives of the study

Description
The problems of increasing the motivation of students of organizations of secondary vocational education and higher education to educational and training activities is due to the use of score-rating approach to recording achievements. The article examines factors that have a negative impact on training and outside training activities, such as TV entertainment, online games, social networks. We consider the activities that have a positive impact on the educational and training activities outside, such as volunteer work, scientific work, socially useful activity. We analyze the advantages and disadvantages of traditional approaches to increase the motivation of students on the basis of a three-level scholarships. The article reveals problems of placing information on the ranking of students in online news sites on educational organizations and media stands. The problems associated with the "transparent" scheme of formation of students rated by forming a student's portfolio have been considered as well. We have given a scheme of a fixed valuation of activities of pupils in points and a formula for calculating the scholarships for student achievements in education and trainings, as well as in volunteer activities. An example of the appearance of a prototype automated system for recording pupils' achievements has been presented. The article also shows data on the implementation of the prototype in educational institutions
