Modern enterprises are steadily developing. Development takes place with different speed, but lack of development leads to reduction activities. The company is constantly introducing innovations to keep the pace of development. The development involves the extension activities. The expansion focuses on the physical boundaries of the enterprises. In the future, its development, the company must predict the time when the estate should be expanded. On the other hand, the extension is not always possible within the boundaries of a given territory. So each company goes through a stage of transformation of its location. The change of place of activity related to the transfer of production capacity, we disclose via the category of redevelopment areas. In European practice, proceedings of the technology of redevelopment have a practice for over 30 years. Russian economy is faced with the necessity of solving such problems, only in the new Millennium. Previously planned organization of the economy is clearly shaped conditions for the functioning of industries and given expert guidance on the timing and the postponements of the proceedings. The Russian economy is building new inter-industry relations and problems of implementation of redevelopment programs are in demand. They affect the interests of the state, construction companies and manufacturers directly. The combination of these market participants need to develop organizational solutions that will not hinder the progressive development of the economy of the region and specific production. © The Authors, published by EDP Sciences, 2017.

Lately, in political and economic circles, a fierce debate on the need for additional monetary emission in Russia. The debate continues to this day. A number of economists and entrepreneurs are convinced of the need for cash injection into our economy to stimulate economic growth. They claim that lack of money hinders economic growth, because the lack of financial resources is hampering investment. At the same time criticized the Central Bank for a set them high key interest rate today at 10 %, which hampers not only investment in the real sector of the economy, but the current actual production. After all, profitability in most sectors of the real economy below 10%. Other economists, including the Government of the Russian Federation and the Central Bank of the country, hold the opposite point of view. They believe high inflation is the main constraining economic growth factor. According to them, only after a drop in inflation, the Russian economy will be able to start growth, and additional money creation will only fuel inflation. Therefore, the first step is to suppress the rising prices, lowering inflation to 4% per annum. In this direction and concentrated all the efforts of the monetary authorities, which are primarily in the key interest rate and limit the supply of money. Of course, the dispute about such issues as stimulating economic growth by an additional cash infusion, should be resolved through analysis of the theoretical foundations and the empirical data obtained in practice, as in Russia and other countries of the world. © The Authors, published by EDP Sciences, 2017.

Phase retardation of both extraordinary and ordinary polarized rays passing through a liquid crystal (LC) cell with homogeneous and inhomogeneous LC director distribution is calculated as a function of the LC pretilt angle θ0 on the cell substrates in the range 0 ≤ θ0 ≤ 90°. The LC pretilt on both substrates can have the same or opposite direction, thereby forming homogeneous, splay, or bend director configurations. At the same pretilt angle value, the largest phase retardation ΔΦ is observed in splay LC cells, whereas the smallest phase retardation is observed in bend cells. For the θ0 values close to 0, 45°, and 90°, analytical approximations are derived, showing that phase retardation depends on LC birefringence variation. © 2013 Optical Society of America.

We find the permittivity of a degenerate electron gas for a collisional plasma. We use the Wigner-Vlasov-Boltzmann kinetic equation with the collision integral in the relaxation form in the coordinate space. We study the Kohn permittivity singularities and reveal their spreading in the collisionless plasma. © 2011 Pleiades Publishing, Ltd.

Expressions for the transverse electric conductivity and transverse permittivity of collisional quantum plasma for an arbitrary value of the degeneracy factor of the electron gas are derived using the Wigner-Vlasov-Boltzmann kinetic equation with the Bhatnagar-Gross-Krook collision integral. Different particular cases are analyzed. Special attention is paid to the case of completely degenerate quantum plasma. The results obtained are compared with Lindhard's formula. © 2012 Pleiades Publishing, Ltd.

A distribution function for collisionless plasma is derived from the Vlasov kinetic equation in the quadratic approximation with respect to the electromagnetic field. Formulas for calculation of the electric current at an arbitrary temperature (arbitrary degree of degeneration of the electron gas) are deduced. The case of small wavenumbers is considered. It is shown that nonlinearity leads to the generation of an electric current directed along the wave vector. This longitudinal current is orthogonal to the classical transverse current, well known in the linear theory. A distribution function for collisionless quantum plasma is derived from the kinetic equation with the Wigner integral in the quadratic approximation with respect to the vector potential. Formulas for calculation of the electric current at an arbitrary temperature are deduced. The case of small wavenumbers is considered. It is shown that, at small values of the wavenumber, the value of the longitudinal current for quantum plasma coincides with that for classical plasma. The dimensionless currents in quantum and classical plasmas are compared graphically. © 2015, Pleiades Publishing, Ltd.

Evaporation of a binary mixture is considered for the case when the evaporating component is a Bose gas. An analytical solution of the problem of the chemical potential jump of a Bose gas is obtained for the case when the molecular collision frequency of the evaporating component is a variable quantity. The dependence of the coefficient of the chemical potential jump on the evaporation coefficient is investigated. The concentration of the evaporating component is assumed to be much less than that of the carrier gas. A graphical study of the coefficient of the chemical potential jump is presented. © 2014, Springer Science+Business Media New York.

In the framework of the Mermin approach, we obtain formulas for the longitudinal electric conductivity in a quantum collisional plasma with a collision frequency depending on the momentum. We use a kinetic equation in the momentum space in the relaxation approximation. We show that as the Planck constant tends to zero, the derived formula transforms into the corresponding formula for a classical plasma. We also show that as the frequency of collisions between plasma particles tends to zero (the plasma transforms into a collisionless plasma), the derived formula transforms into the well-known Klimontovich-Silin formula for the collisionless plasma. We show that if the collision frequency is constant, then the derived formula for the permittivity transforms into the well-known Mermin formula. © 2014 Pleiades Publishing, Ltd.

We derive formulas for the transverse electrical conductivity and the permittivity in a quantum collisional plasma using the kinetic equation for the density matrix in the relaxation approximation in the momentum space. We show that the derived formula becomes the classical formula when the Planck constant tends to zero and that when the electron collision rate tends to zero (i.e., the plasma becomes collisionless), the derived formulas become the previously obtained Lindhard formulas. We also show that when the wave number tends to zero, the quantum conductivity becomes classical. We compare the obtained conductivity with the conductivity obtained by Lindhard and with the classical conductivity © 2013 Pleiades Publishing, Ltd.
