The article is devoted to the development of identification criteria of the investment strategy of machine-building enterprises using the data of the accounting (financial) statements. The type of investment strategy to determine it is proposed to use a combination of three criteria, including the share of spending on modernization of the payments of the organization, the share of the upgrade costs in the cost of fixed assets and the share of portfolio investments in the payments of the organization. the author identified seven types of investment strategies engineering enterprises, depending on the combinations of values of these criteria. The advantage of such approach is that interested external users of financial information about the activities of enterprises, including potential investors, will be able to assess the type of the current investment strategy of the enterprise, and its possible change. These results can be used in the development of programs for the development of investment activity at the regional level.

It is known that the presence of particles in the lubricating fluid additive or wear products, and also due to its molecular orientation of the wall near the solid support surface bearing lubrication is separation into layers of different viscosities. Laminar flow of a viscous incompressible fluid in the gap of the thrust and radial bearings considered in [1-16]. A significant drawback of the proposed methodology here is that the computational model is ignored pressure dependence of viscosity. For large values of the pressure in the lubricating layer of lubricant viscosity increases significantly, and there is a need to address the dependence of viscosity on pressure.

In the presence of liquid lubricant particles precipitate from wear products or additives, as well as from the wall of the adsorption and chemisorption on metal surfaces contacting bearing surfaces separation occurs at the layers of lubricants with different viscosity properties. For viscous incompressible stratified lubricant in the gap thrust and radial bearings seen in the works. A significant drawback of these studies is that the calculation model is ignored pressure dependence of viscosity. For large values of the pressure in the lubricating layer of lubricant viscosity increases significantly, and there is the need to address the dependence of viscosity on pressure.

The most important problem of the city is that of economic entities with emission sources, developing projects of maximum permissible emissions (MPE) on their own sources of emissions, and the effect of summation of pollutants from all sources combined into the atmosphere of the city today moment, unfortunately, has not been investigated. An inventory of sources of emission of pollutants into the air, the optimization of observation posts and conduct the calculation of the dispersion of pollutants in Volgograd help to display detailed picture of air pollution in the city. Some problems in the development of a consolidated draft MPE invited to use the balance sheet liability method of pollutants in the city.

In article questions of the centers of social tension in the student's environment are considered. As one of such centers the size and structure of a payment for accommodation in hostels of the educational organizations of the higher education acts. On tasks of the Ministry of Education and Science of the Russian Federation a number of monitorings of cost of hostels is carried out, the comparative analysis is made, the received results are analysed, the corresponding conclusions are drawn.

In this paper, based on a system of equations of motion of a viscous incompressible fluid with the viscosity depending on the pressure, and continuity equations, provides self-similar solution using the current functions of the stratified flow of lubricant in the thrust bearings. The proposed model is calculated in contrast with the existing three-layer stratification, further complicated by the dependence of the viscosity of the lubricant pressure. An analytical expression allows to obtain a description of three-layer stratified fluid lubricants and a graph of the effect of structural parameter and viscosity ratio stratified layers on the basic performance of the bearing. Numerical analysis of the dependence of the parameters of the adapted profile and load-carrying capacity of lubricating layers.

Keywords: three-layer lubrication, maintenance power circuit adapted slider, stratified flow, pressure dependence of viscosity.

The article is devoted to the solution of problems of effective and safe management in the global scale of the space as a whole and in individual territories. The relationship of economic and environmental security of the world community can be characterized as socio-ecological and economic security, which characterizes the steady state of progressive development of society based on sustainable use and protection of natural resources as a basis for her life under the destructive influence of various external and internal factors. In addition, because the processes associated with security, in essence, are the management, we also need the presence of the subject, ensuring safety,which is considered the productive sector of the economy of each state.
