Description
Under consideration is the international experience of NCFU in developing student mobility via French resource center. Today, in the era of globalization, student academic mobility is the integral part of the process of integrating higher education establishment into common European educational framework. Emphasis is made on the academic environment as an important factor of realizing international student mobility. Tendencies towards open academic environments set up new possibilities for academic exchanges both with foreign and Russian – based academic establishments. Thus, we can talk both about inner and outer student and teacher mobility, which is realized individually as well as on the institutional level. Conclusion is made that academic exchanges can be viewed upon as means of developing and renewing higher school educational programmers in Russia. This can eliminate exclusiveness of Russian educational system; pave the way for obtaining recognition of its educational programs; secure transparency and acknowledgment of competences and qualifications to raise student mobility and competition of Russian educational programs in the world market of educational services. The experience of NCFU in developing international activity discussed in the article illustrates the theoretical base of the research because empiric data well integrates into the framework of academic mobility

Description
The article is dedicated to a numerical investigation of a plane problem of the oscillation amplitude of a buried source, depending on the frequency and motion speed in various isotropic media. Three types of the medium are considered: a two-layer package with a rigidly fixed base, a two-layer package with a mechanically free base, a half-space. The source, in the form of a stress jump simulating a rigid inclusion of small dimensions, moves in the interface plane at a constant speed. Homogeneous boundary value problems are considered in a moving coordinate system associated with a source. The solution method is based on the usage of integral Fourier transforms, the method of direct contour integration and algorithms for constructing symbols of Green's matrices. The method of direct contour integration significantly simplifies calculations in comparison with the traditional approaches to the calculation of Fourier integrals. We have presented calculations of nine amplitude-frequency and amplitude-velocity characteristics for different combinations of medium and source types, that give an exhaustive qualitative and quantitative description of the solutions for boundary value problems in a wide range of velocities and frequencies. Comparative analysis of calculations showed a primary influence of the type of an elastic medium on the investigated characteristics, as well as the large influence of the source type. Which, in turn, revealed some substantial connections between the boundary value problems with a moving source and the corresponding problems with a stationary source

Description
The influence of auto-displacement in a resonancetunnel diode (RTD) on the dynamic range of amplifiers on these diodes is considered in the article. The amplification at resonance frequency is considered and the influence of higher harmonics is not taken into account, since they do not create a significant voltage drop at the nonlinear resistance of the diode. It is assumed that the gain will be sufficiently large, and then the nature of the dependence of the gain factors on the degree of regeneration will be the same for amplifiers "per pass" and "reflection". This allows us to consider the problem for both types of amplifiers on the RTD. The types of amplitude characteristics , which are possible for the RTD amplifier, are considered. The dependences of the parameter determining the dynamic range of the amplifier on the position of the operating point for several values of the product of the resistance on the direct current of the supply circuit are calculated for the value of the modulus of the maximum negative conductivity of the tunnel gap RG max. For each value of RG max for given parameters, you can determine the position of the operating point, which provides the specified amplifier mode. Dependences of the value of the dynamic range are constructed with allowance for auto-displacement and in the absence of auto-displacement for two values of the degree of regeneration. Taking into account autosplacement, two possible types of amplitude characteristics and boundaries of their existence were revealed. For these two types of amplitude characteristics, expressions were obtained that determine the dynamic range of the amplifier

Description
The work is done in scientific and practical directions for minimization of power losses in transmission of electricity to local distribution networks between the actors of the energy (producers and consumers) of energy-saving technologies focused on technological activities such as modernization and reconstruction of networks. Quite often in various circuits of power systems, it is advisable to transfer energy and its power through intermediate (transit) nodes. Structural changes in the electricity sector, at present, are mainly associated with the introduction of market relations between the subjects of energy exchange; therefore, in this work special attention is paid to the problem of calculating the power losses, as it is nonlinearly dependent on the power at the nodes and branches of a network. It should be noted that the nodes in problems transit capacity could be both sources and consumers. The latter necessitated the need for search of possible ways to reduce transportation losses of energy due to both the improvement and optimization of distribution networks and through the use of intermediate transit nodes. It follows that the transportation problem in this formulation is more General and expands the possibilities of optimization of power losses for the local subsystems of the energy clusters. The work is composed of the transport matrix for solving problems transit capacity, where the algorithm taking into account the distinctive features of which consist in the use of continuous numbering of sources and consumers in the matrix, and any node can be a transit country. The transit capacity ii-th node Zii=0, and the dimension of the matrix in contrast to the previously considered tasks has (n+m) (n+m) and it remains square as all the transport problems of linear programming. Transit variables Xii are included in the solution of the problem with a minus sign, and all transit variables are considered basic. From the above example in the work of a number of branches of a network is minimal, which significantly reduces the cost of building and maintaining the network, and the solver minimizes the power loss between the subjects of energy exchange and, as a result to savings from the standpoint of cost of construction of the network and the management of overflows of energy in it

INTERRELATION OF THE MODEL OF CALCULATIONS OF ATOMIC RADIUS AND VARIOUS SYSTEM CHARACTERISTICS
Description
In this article, we discuss the relationship between the previously obtained model for calculating atomic radii with electrodynamics, the hydrodynamic model of the planets of the Solar System, and the R-function of the structural organization of electronic systems. It is shown that the curve of the dependence of the value of the correction coefficient e x on the atomic number of the element in form coincides with the dependence of the ionization energy on the mass of the atom and the R-function on the nuclear charge. The concept of the "atomic nucleus potential", which takes into account the energy of the nucleus and the charge of the nucleus of the atom, is introduced. It is shown that the radius of an atom is the product of the nuclear potential by a factor kx , taking into account the characteristics of electronic levels; the energy of the nuclear reaction is the work of the forces of the field (potential) of the atomic nucleus along the displacement of the atomic charge. The dependence of the potential of the nucleus on the charge number in the Mendeleev’s Periodic Table is shown. It is shown that any system of satellites (or atomic shells) has a constant ratio of its Kepler number to the mass of the central body around which they rotate. It is shown that in the Table of Mendeleev's chemical elements and in the solar system, the fundamental value is the mass of the center (the nucleus of the atom or the center of the orbit). The ratio of the Kepler number to the mass of the central body is a constant, within the accuracy of construction and calculations

06.00.00 Agricultural sciences
Description
In the article there were analyzed the different approaches of Soviet and Russian authors to the assessment of soils regarding to agro-ecological factors. There was given the characteristic of natural-economic zones territorially entering the Azov-Kuban lowland by main soil-climatic indexes. There was considered the valuation of soils which determines their relative value and suitability on main factors of natural fertility or their groups, it serves as a criteria of unification of soils into agro-ecological groups. There were shown the main indexes and order of grouping of soils under unification of different soils into agro-ecological groups. There was calculated the “normative” productivity of main agricultural crops on natural-economic zones of Azov-Kuban lowland which defines the agro-productive value of soil. There were revealed the disadvantages of soil assessment method used in the course of state cadastre valuation of agricultural lands asserted by the order of the Ministry of Economic Development from 20.09.2010 № 445. There were cited the specific rates of cadastre cost (SRCC) of agricultural lands on municipal entities of Krasnodar region. There was given the assessment of obtained data regarding to natural-climatic factors of the region, there were made proposals on optimization of trends of further researches on claimed problem

IMPACT OF INTEREST CENTRAL BANK POLICY ON DEPOSIT POLICY OF COMMERCIAL BANKS
Description
The article is devoted to the evaluation of the influence of the interest rate policy of the central bank (CB) on the deposit policy of commercial banks. The author analyzes the dynamics of the Central Bank's key interest rate, weighted average interest rates to individuals funds obtained raised by credit organizations. Particular attention was paid to regression analysis to determine the dependence of rates on deposits of individuals from the Central Bank's key rate. The authors presented the forecasted values of interest rates on deposits of individuals, which clearly demonstrate the current situation of the deposit policy of commercial banks. A number of indicators that affect the change in interest rates on deposits of individuals are considered. In addition, the main positions on improving the deposit policy are presented. The conclusion is drawn that interest rates on deposits depend on a whole spectrum of both external and inner banking components. Each bank develops its own deposit policy, determining the terms, types of deposits and their interest, terms of conducting deposit operations, relying on the specifics of their activities and taking into account the factor of competition with other banks and the inflationary processes that occur in the economy
