06.00.00 Agricultural sciences
DescriptionThe article presents the materials of research on studying of influence of various levels of crude fat in the complete feed (CF) for the young geese of Lindovskaya breed on chemical composition and organoleptic quality of goose meat. In the experimental groups we increased the concentration of crude fat in the start and finish of the CF to 7.4 % and 6,85 %, respectively. As the lipid supplement, we used sunflower oil. It is established that muscle tissue of geese, consuming finishing CF with sunflower oil, has a more pronounced taste, odour, tenderness and juiciness. We may highlight the tendency to increase the proportion of monounsaturated oleic acid, in the background of the decrease of specific weight of palmitic acid in the fat muscle 60 day goslings who received the start and finish of CFs with the addition of sunflower oil

CONCEPTUAL FOUNDATIONS FORMATION OF INFORMATION SECURITY SYSTEM FOR A PRODUCTION ENTERPRISE
DescriptionIn connection with the informatization of production, scientific-technical, social and public activities, the emergence of the digital economy, there is a need to protect effectively sensitive and confidential data. The solution to the problem of creation of system of information security becomes particularly relevant and significant, since with the advent of complex automated information systems significantly increased the quantity of information stored in the computing device, in single databases have become integrated information for various purposes, greatly expanded the number of users having access to the information resources of the enterprise. In the article, we have proposed and scientifically based conceptual foundation and principles of construction of modern system of protecting information files to manufacturing enterprises, which constitute commercial secret, from damage and unauthorized access. We have identified the information that requires protection from competitors and intruders, identified infrastructure their protection and the mechanisms for their own reliable operation of protective systems. It is shown that the objects to be protected from potential internal and external threats and illegal acts are staff, material, financial and intellectual resources, means and systems of informatization and protection of all types of resources. The basic principles of information security production of the enterprise are the mutual responsibility of management and staff, legitimacy, cooperation with law enforcement bodies, maintenance of optimum balance of interests of the company and the individual

Description
The integration of producers of raw materials and its processors into the agro-industrial complex is connected with the social division of labor, its specialization, the need for interaction between specialized branches and types of agro-industrial production. Agrarian enterprises are united in an effort to reduce the risk, the emergence of which depends on the climatic conditions, the spontaneity of the agricultural market, the dictates of processing enterprises, the need to increase the competitiveness of production. In the Russian practice, there were various organizational forms of integration, differing in the nature of economic ties between participants, the degree of independence of the enterprises entering the association, the combination of centralization and decentralization of management. Conventionally they are divided into associative - "soft" and corporate - "hard." The "soft" forms of association include as-association, union, non-profit partnership and strategic alliance. They can effectively function at the interregional level. A rigid type of integration ties is characteristic for combines, concerns, trusts, holdings. Agricultural consumer cooperatives are voluntary associations of legal entities and individuals residing or operating in a certain rural area on the basis of membership and pooling of money units in order to meet the needs of members in credit resources and other banks services. The conditions for the emergence of sustainable integrated associations in the agroindustrial complex require qualitative and quantitative analysis based on mathematical modeling

Description
The article is an author's view on the problem of innovation and innovation environment applied to the oil industry of the country and its regions. The main task set by the authors during the study is the development of theoretical provisions for determining the priorities for the formation of an innovation environment in the Russian oil and gas sector and the development of methodological recommendations for the improvement of the innovation environment. For this purpose, the following tasks were accomplished: the essence of the innovation environment of the oil industry as an economic category was revealed and the priorities of its formation in the oil and gas complex of the region were justified; the methodological bases of the innovation environment analysis are substantiated and the priorities of its formation in the economy (structure, functions, indicators) are revealed; proposals to improve the innovation environment in the oil-producing region have been developed; methodical recommendations on the development of innovative processes in the industry have been formed. Concerns about fuel safety, environmental problems are growing in the society. Therefore, in this article, the authors propose their own approaches to the organization of interaction between the subjects of regional oil and gas markets, the external environment and municipal and state authorities on a science-based basis.

Description
With the aim of improving the productivity and performance of the sunflower seed separation process in the air-sieve seed-cleaning machine called MVU-1500 its multivariate analysis was carried out. The main indicators of the seed heap separation process were determined according to the feeding of the seed heap onto the sieve of the lattice. The indicators are as follows: completeness of the j-th components screening, the j-th components content in the sieve path, the completeness of their discharge and their content in the discharge from the sieve tier. Having adopted the hypothesis of a possible increase in the efficiency of the separation process in the air-sieve grain cleaning machine, we analyzed the delivery patterns of seed heap components into the pneumatic channel with the aim of optimizing the process. For a more complete assessment of the process indicators under consideration, basic patterns of movement of various components in the sieve-tier lattice were estimated. It was taken into account that in modern designs of air-sieve grain cleaning machines seeds are fed into the pneumatic channel from the sieves. When the width of the lattice is equal to one, the density of the j-th component of the seed heap is constant along the length of each sieve in the stack of sieves and the separation coefficient is constant along the length of the sieve, the expression received estimates the average speed of movement in the first sieve-tier lattice in the steady process of separation. There was evaluated the statistical significance of differences of the j-th component average speed movement on the second sieve- lattice by Student's t-criterion, which showed that they belong to the same sample of random variables and do not have statistically significant differences. Therefore, we can obtain the following velocity values of the heap of sunflower seed movement in the sieve-tier lattice: fragments of stems velocity is 0.0518 m/s; milled seeds velocity is 0.0381 m/s; velocity of sunflower seeds less than 3.2 and 3.2-3.6 mm thick is 0.0835 m/s, velocity of sunflower seeds of 3.6-4.0 mm thick is 0.0453 m/s, that of more than 4.0 mm thick is 0.0410 m/s

SIMULATION OF BALL LIGHTNING IN CONDUCTING ENVIRONMENT
01.00.00 Physical-mathematical sciences
DescriptionIn this work, a model is developed to describe the formation of streamers, plasmoid, and ball lightning in a conducting medium. To describe the contribution of the conductivity currents, we modified the standard electrostatic equation taking into account the vortex component of the electric field. As a result of this generalization, a system of parabolic-type nonlinear equations is formulated that describes the formation of streamers, plasma long-lived formations and ball lightning. As is known, in laboratories it is possible to create a plasmoid with a lifetime of 300-500 ms and a diameter of 10-20 cm, which is interpreted as a ball lightning. With high-speed photography, a complex structure is detected, consisting of a plasmoid and surrounding streamers. Within the framework of the proposed model, problems are posed about the formation of a plasmoid and the propagation of streamers in an external electric field. In this model, the plasmoid is considered to be a long-lived streamer. The range of parameters in which a plasmoid of spherical shape is formed is indicated. It is established that there are three streamer branching mechanisms. The first mechanism is related to the instability of the front, which leads to the separation of the head of the streamer into two parts. The second mechanism is associated with the instability of the streamer in the base region, which leads to the branching of the streamer with the formation of a large number of lateral streamers closing the main channel of the streamer to the cathode. In numerical experiments, the third branching mechanism observed in experiments connected with the branching of the plasmoid in the cathode region with the closure of the space charge to the anode through the streamer system was observed. The results of modeling the evolution of globular clusters in a scale of hundreds of milliseconds are given. Plasma exchange recharge modes leading to the formation of a positive or negative charge of the system are found
