The combination of the unique, abnormal properties shown by oxidic systems with structure of spinel on the basis of transitional elements chromites draws attention of researchers for many years. Some systems on the basis of transitional elements chromites (for example, nickel and copper chromites) have critical elements (multicritical points, lines of phase transitions of the second sort, etc.) on the phase chart. Near these elements of the phase chart materials possess unique chemical and physical properties. Therefore development methods of receiving and research of phase forming and properties in NIO-CoO-CuO-Cr2O3 system represent fundamental and practical interest for chemistry and technology of inorganic substances. In this work processes of spinel structure formation in system 0,6 NiCr2O4 – 0,2 CoCr2O4 – 0,2 CuCr2O4 from crystal chemistry positions are considered. Formation of two solid solutions on the basis of nickel (II) chromite – with structure of cubic spinel and with tetragonal distorted structure is established. The influence of cooperative Yahn-Teller effect on processes of a spinel forming and on stabilizing impact of chloride of potassium on process of education of two spinel solid solutions is suggested. Influence of a power factor of cation stabilization in knots of a crystal lattice as one of the important factor in reaction of spinel structure formation is considered.

The paper is devoted with the analysis of sources and volumes of oil components’ input into the Black sea. The topicality of this problem is connected with of transboundary the status of water object that contributes to the complexity of such works. Black Sea has important significance for transport and development in the coastal zone of the oil complex, combined with a great recreational potential. As a result, ecosystems are technogenic impact. The paper describes the main natural and anthropogenic sources of oil components in the Black Sea. On the basis of the results of our expeditionary research and analysis of sources of pollutant concluded chronic character oil pollution of the Black Sea. And the conclusion that the most optimistic estimates, entrance of oil components in the ecosystem in the Black Sea is approximately 270 thousand tons per year, which is higher than the currently accepted values of 2−2.5 times.

In this paper, based on Darcy equations that govern the lubricant in porous layers , and the modified Reynolds equation in the framework of a short bearing solve the problem of unsteady motion of a viscous incompressible lubricant in the bearing clearance double-layer porous . Here we consider the case when the permeability in porous layers in the axial direction is changed by the normal law , and the combined feed lubrication is performed simultaneously in the axial and perpendicular to the bearing axis directions. As a result, the pressure field found in porous layers and in the lubricating layer and analytical dependences for the efforts of the oil film . Compiled by the equation of motion tongue and solved the problem of the stability of the unsteady motion of a pin bearing , found that in the case of a combined bearing lubrication working more steadily compared with the cases or axial directions perpendicular to the axis lubrication . The results obtained can be offered for the development of cylindrical dampers with double-layer porous collar , effectively attenuating transmitted force imbalance in the combined feed lubrication.

The article deals with development of hydropower in the Altai region. Indicates the need for widespread adoption in the economic practice of farms renewable energy. Provides information about the basic types of equipment of small hydro power plants. Analyzes the main problems encountered during the construction and operation of small hydroelectric power plants. In this time have a potential for the construction of small hydroelectric power stations for the needs of farms in the area of the foothill zone of the Altai Territory. It is noted that the implementation of such a project is possible only at the state level, because of the large amount of necessary investments. As a priority area of hydropower development for the needs of farms Altai proposed project of building 26 small hydro power plants on the rivers Charysh, Anouilh and Peschanaya. Indicated that the project could provide more than 95% of the needs of agriculture in the region's electricity . According to the analysis of the above issues,we can the following conclusions: (1) small hydropower plants are spent in terms of technology and affordable source of renewable energy, and (2) is now possible to create a sufficiently large hydroelectric complexes of low power, the ability to make a significant contribution to the region's energy supply structure and (3) the market has a large number of manufacturers of equipment for hydroelectric small power, including and domestic enterprises, which allows to put into practice projects by individual energy supply, without any technical difficulties, (4) the high priority in the development of small hydro power plants, in relation to the needs of the agriculture of the Altai Territory is to create a pool of 26 small hydro power plants on the rivers Charysh, Anouilh and Peschanaya with a total installed capacity of 404 MW, with an annual production volume of 1540 million kWh of electricity per year, and (5) small hydropower plants are a priority of energy supply based on renewable energy sources of agrarian industry in the foothills southeast of Altai Territory.

The current system of intergovernmental fiscal relations , the trends of its development in Russia , including the alignment process , aimed at smoothing the territorial differentiation of socio- economic development of regions. The main task of any state , regardless of the device is to smooth regional disparities through a reallocation of financial resources. In this case, the stability of intergovernmental fiscal relations between the federal center and the subjects of the federation is largely determined by well-functioning system of fiscal federalism. Currently, the budget process is characterized by serious contradictions that arise during the development phase as well as on the stages of implementation of management decisions. Global experience demonstrates the lack of an optimal model of intergovernmental relations . Vertical alignment is the process of achieving a balance between the commitment of each level of government expenditure with the potential of its revenue sources . The tools include the vertical alignment of the fixing of taxes for a certain level , subventions and subsidies, regulating the distribution of income. The horizontal alignment is aimed at providing a unified standard level of consumption of public services to the residents of different regions of the country. With reference to the Russian economic space horizontal alignment problems are quite complex , since there are strong differences in socio-economic development of the regions due to climatic and historical factors .

Fe-doped AlN nanorods were studied by means of x-ray absorption spectroscopy above the Fe K- and L2,3- edges. Theoretical simulations of the x-ray absorption spectra show that Fe atoms mainly substitute Al. A minor fraction of Fe interstitials or Fe-Al-N ternary alloy can be identified as well. Bader’s AIM analysis predicts that neutral substitutional FeAl defect is in 2+ charge state, though Al in pure AlN is in 3+ charge state. Fe L2,3 absorption spectra and photoluminescence data indicate the coexistence of Fe2+/Fe3+ in AlN:Fe nanorods so different charge states of substitutional FeAl should co-exist.
