01.00.00 Physical-mathematical sciences
Description
This article is a continuation of the previous works of the authors [The influence of reaction dissociation / recombination of molecules of water on transportation of electrolyte 1:1 in the membrane systems in the diffusion layer. Part 1. Mathematical model // Scientific journal of Kuban State Agrarian University, 2016. No. 07(121) and The influence of the reaction of dissociation / recombination of molecules of water on transportation of electrolyte 1: 1 in membrane systems in the diffusion layer. Part 2. Asymptotic analysis // Scientific journal of Kuban State Agrarian University, 2016. – №08(122)] and devoted to assessing the possibility of gravitational convection due to the recombination of hydrogen and hydroxyl ions. The article presents the solution of a boundary-value problem, which is a mathematical model of electrodiffusion for the four types of ions at the same time (two ions of salts and hydrogen and hydroxyl ions) in the diffusion layer in electro-membrane systems with ideal selective membrane, with the heat transfer equation and the Navier-Stokes equation. The article shows the possibility of the emergence of gravitational convection due to the exothermic reaction of recombination of water molecules in the depth of the solution. The article considered the reaction of recombination of hydrogen ions and hydroxyl, although the main results can be applied, after appropriate modifications, and to amfolit-containing solutions, such as wine, juices, dairy products, microbiological processing of biomass (amino acids, anions of polybasic carboxylic acids), municipal effluent (anions of phosphoric acid), etc.

VYBORG’S PERIOD OF A GREAT RUSSIAN ARTIST NICHOLAS ROERICH
Description
A Karelian stage in the life of the great Russian artist, Nicholas Roerich, is relatively well-known. However, researchers have not been practically studied the period of residence of the Roerich family in Vyborg. It is known that N. Roerich was friends with the Finnish artist A. Gallen-Kallela, who helped him to remain in Finnish Vyborg in the period of revolutionary events in Russia. From October 1918 to May 1919 the Roerich family lived in Viborg in Ladaunkatu (now Turgenev St.), №8. The painting «Autumn» (1919) was written by the artist during the Vyborg’s period. The painting was created in a fantastic manner which was usual for the artist. Unfortunately, at the moment nothing is known about his other works with views of Vyborg. However, in the catalog of his works, published in the USA in the 1920-es , under the name of each picture is given information about where and when it was created. Thus, under some of the works of the artist is the mark: «Painted in Viborg». So, today we can say about some works of master, which he wrote in Vyborg. In the first place, there are famous paintings of the artist: «Repentance», «Call of the bell. Old Pskov», «Sons of the Heavens», «The heat of the Earth», «Autumn – Vyborg», «Les Miserables (Outcast)», «Treasure» and others. As well, in 1918 at the time of staying the family in Vyborg a number of sketches in "Vyborg Notebook" were made by his son, Svetoslav Roerich, who was then 16 years old. Probably, inexhaustible diligence of Roerich gave a rise to other works with the theme of Vyborg, which scientists do not know because this topic has not been investigated

01.00.00 Physical-mathematical sciences
Description
Specially formed mixtures of isotopes of chemical elements have better consumer properties than their natural counterparts. Therefore, the development of methods for increasing the efficiency of the known methods for producing of isotope materials is relevant. It is known that the chemical bond is formed only in the singlet state of the spins of valence electrons of the reagents. On the basis of the known representations about dispersion of spin projections on the coordinate axes and the molecular-kinetic theory of gases was obtained an expression for the constant of the chemical reaction between the radicals occurring in the magnetic field. This expression allows calculating the reactivity of the isotopic modifications of radicals. Plasma allows to transfer many of the compounds in the gas phase. It is known that a significant part of particles in low temperature plasma is in a radical form. The equations of chemical kinetics for describing the process of oxidation of the carbon isotopes in argon-oxygen plasma occurring in an external permanent magnetic field were written in the work. It was shown that the efficiency of plasma process of isotopes separation can be increased only under insufficient oxygen relative to the stoichiometric value. These equations of chemical kinetics of processes occurring in the plasma process of incomplete oxidation of carbon isotopes needed to find experimental conditions that provide the maximum isotope effect in a magnetic field

THE GENESIS OF THE "LEARNED IGNORANCE" DOCTRINE AND IT'S COGNITIVE VALUE
Description
A clarification and interpretation of the philosophical meaning of the "learned ignorance" doctrine, viewed from an aspect of a history of philosophy, involves a necessity to educe a genetic and essential relationship between the "learned ignorance" principle and the apophatic tradition of thought. The article describes the genesis of the "docta ignorantia" principle: it appeared in a context of theology as a method for attaining of the knowledge of God. It is this concept that often forces researchers to restrict the epistemic potential of the "learned ignorance" principle, leaving it in limits of negative theology and mystics. However after investigating the difference between the philosophical and the religious understanding of theology the authors of the article interpret the paradigm of the "learned ignorance" to be a fundamental philosophic principle of thought and cognition. Nowadays it is widely accepted, that the paradigm of the "learned ignorance" in it's classical form originates from the apophatic tradition. The article points out, that the representative examples of apophaticism, which could be found in the christian theology, on the one hand, were based on a solid philosophic tradition (predominantly platonic and neoplatonic), and on the other hand, did not complete a spread in a world philosophic thought of a definite (apophatic) tradition, which had an intimate connection with the paradigm of the "learned ignorance", postulating as it's main intention a seemingly paradoxical comprehension of the Absolute, supposed to be absolutely incomprehensible. The results of the scientific research in a field, thus defined, are presented briefly in this article

STATE REGULATION OF REGIONAL FOOD SECURITY IN THE SANCTIONS REGIME
Description
We have analyzed the system of state regulation of regional food security and substantiated the main directions of its software under the sanctions regime, presented the scheme of the constituent elements of regional food security, including the purpose and the main task. We have revealed the features of the modern food problems of Russia and its regions, systematized the negative effects of international sanctions, assessed the obstacles to implementation of the accelerated import substitution policy. An analysis of exports and imports of basic foodstuffs in the Krasnodar region for 2011-2015 has been shown. We have also presented the dynamics of the average per capita consumption of food among the population of Russia and the Krasnodar region. The work substantiates the necessity to diversify trade relations and the search for potential investors for the implementation of pilot innovative projects in the real sector of the economy of the region. It substantiates the actual directions of optimization tools of state regulation of the food security of the Krasnodar region in the conditions of modern economic realities. It is proved that the effective implementation of the regional agricultural policy requires a development strategy for the agricultural sector, which expresses the priority of the state in relation to agriculture and includes the presence of a real agrarian protectionism

DYNAMICS OF RELATIVISTIC PARTICLES IN THE RING AND SPIRAL GALAXY METRIC
01.00.00 Physical-mathematical sciences
Description
In this work, we examine the dynamics of relativistic particles in the ring or spiral galaxy metric in general relativity. On the basis of the solution of Einstein's equations we have derived metric having axial symmetry, comprising N centers of gravity and a logarithmic singularity. The application received metrics to describe the motion of particles in a spiral and ring galaxy. On the basis of Einstein's equations solutions for vacuum we are explained rotation of matter in spiral galaxies. An expression for gravitation potential in the inner region of spiral galaxies in agreement with experimental data on the rotation of the CO and hydrogen is described. It is established that in the metric with N centers of gravity which are distributed on the circumference, exist as a local motion near the center of gravity, and motion around N gravity center as well. The transition from one mode of motion to another is determined by the initial distance to the circle on which the distributed centers of gravity. A system of non-linear parabolic equations describing the evolution of the metric in the Ricci flow proposed. The boundary problem for the gravitational potentials in the Ricci flow was formulated. There are applications of the theory to describe a spiral and ring galaxy
