MONUMENTS OF THE FEBRUARY AND OCTOBER REVOLUTION IN THE TERRITORY OF RUSSIA
DescriptionThe article is devoted to the study of the monuments of revolutions of 1917 in Russia. It is emphasized that from the historical point of view, almost all monuments represent the embodiment of the losses and sufferings of humankind in various armed conflicts. This is especially true for the revolutions of 1917, which changed the entire modern history of the country, and even after 100 years cause a special interest both in the international scientific community and among ordinary people. This study specifies that after the final establishment and approval of the Soviet government, the new government realized that it was needed to create a certain basis, namely, its political symbolism as a foundation for the formation of image of the new government. The most important component of this process was the desire of the authorities to the formation of the ideas of the Soviet people about themselves and their place in the world, and, as a consequence, the folding of the foundations of Soviet patriotism, because the new generation who had no idea about the Russian Empire, began its life in the country, which had an ideology, but just started to develop the system of socialist values. The attention is paid to the fact that the monuments are one of the important elements of the historical and cultural heritage, which reflected the past experience of mankind, broadcast through architectural and sculptural symbols to the present, which contributes not only to the cultural enrichment of mankind, but also used by people to influence worldviews contemporaries. The article says that modern youth need to know the history of their country, not to forget about the numerous victims of various wars, to preserve peace and appreciate life

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

SPECIAL CASES OF INVERSE MATRICES
01.00.00 Physical-mathematical sciences
DescriptionThe inverse matrix for the square matrix A of order n with coefficients of some field exists, as it is known then and only then, when its determinant is not equal to zero. If the matrix A has a certain type (certain structure), then an inverse matrix A-1 should not have exactly the same structure. Therefore, it is interesting to describe such square matrices A, which have an inverse matrix A-1, having the same structure as the matrix A, under certain conditions. For example, a subdiagonal matrix with nonzero elements on the main diagonal has an inverse matrix over a field of characteristic zero, having also the form of subdiagonal matrix. Similarly, an inverse matrix towards symmetrical or skew-symmetric matrix is also symmetric or skew-symmetric accordingly. Also, the matrix inverse to non-degenerate (nonsingular) circulant will be a circulant itself, and finally, the matrix inverse to nonsingular quasdiagonal matrix D will be quasdiagonal itself, and will have the same partitioned structure as D. Thus, there is a problem of determining these types of nonsingular matrices that have an inverse matrix of the same type as a given matrix. In line with this problem in the present study it is determined such type of matrices for which an inverse matrix has the same type, at that the conditions are identified in explicit form, ensuring the nonsingularity of the matrix. The matrices of three orders are shown in detail. These results allow determining the characteristics of fields over which there are inverse matrices of the considered types

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

06.00.00 Agricultural sciences
DescriptionFor the research period (2003-2016), 57 pest species and 46 pathogens were recorded on stone and pomaceous fruits in humid Russian subtropics, among which the representatives of the order Lepidoptera and the division Ascomycota predominate. The greatest number of the species was recorded on the apple tree - 35 pests and 25 pathogens, the smallest - on cherry and sweet cherry trees (13 and 10, respectively). 43,7 per cent of the species are polyphages, while the relative abundance of monophages among fungi is higher than among arthropods. The species with activity in the summer are prevalent. A group of species that are harmful in humid subtropical environments all year round (11 species of phytophages and 19 pathogens) was identified. Analyzing the changes in the species composition of the complex through the time, we can speak about the relative stability of the dominant species. The group of the typical dominant species of pests for almost a century has included Grapholita molesta Busck., G. funebrana Tr., Cydia pomonella L., Taphrina deformans (Berk.) Tul., Stigmina carpophila (Lév.) M.B. Ellis, Monilinia laxa (Aderh. et Ruhland) Honey, M. fructigena Honey, Podosphaera leucotricha (Ellis & Everh.) E.S. Salmon, Venturia carpophila E.E. Fisher and pear V. pyrina Aderh. Eriosoma lanigerum Hausm., Scolytus mali Bechst. and Tranzschelia prunispinosae (Pers.) Dietel are currently dropped out from the group of the dominants; Halyomorpha halys Stål, which is a new pest for Russia, was added. Groups of the species with sharp fluctuations in abundance or frequently encountered were distinguished

Description
The article compares various hypotheses that explain the mechanisms of the influence of the magnetic field with different characteristics on liquids, physico-chemical and biological systems. Physical effects that cause specific biological activity of water (magnetic treatment of water, production of thawed water, degassing, etc.) make water be metastable or non-equilibrium states. Water attracts the attention of researchers as a likely universal mediator in the transmission of electromagnetic field signals to the biological level. Water is involved in a variety of chemical and metabolic reactions, so the question about the ability to change the properties of water and solutions under the influence of fields of different nature: an electromagnetic field with different frequencies, with different combinations of field orientations (parallel constant and variable magnetic field, slope fields, rotating magnetic fields, magnetic fields close to zero and electric fields) arises. At the heart of existing methods for treating liquids lie methods that use the energy of the acoustic and magnetic fields, as well as complex methods of influencing the electromagnetic field in combination with thermal heating, pressure change, etc. The analysis of existing hypotheses about the mechanisms of the influences of fields of a different nature on the treated liquid makes it possible to put forward a hypothesis about the possibility of the joint influence of the acoustic and magnetic fields on the liquid by means of the acoustic and magnetic device
