To describe the dynamics of the temperature field in the surface layers of the earth taken up the heat balance of the earth's surface. Taken into account are three components of the heat flow: convective heat transfer with air, solar radiation, heat flow from the surface layers of the soil. The boundary conditions on the surface of the soil is considered the temperature of the ground surface, which is determined from the heat balance of the surface layer of the sun radiation. The temperature distribution in the soil is determined using the method of finite differences. A layer of soil has a certain thermal inertia, which leads to delaying the achievement of minimum temperatures in the soil column relative to the time of achievement of the minimum surface temperature. In the surface layer of soil to a depth of approximately 300 mm, is almost complete attenuation of the diurnal temperature fluctuations in the month of June with account of solar radiation in conditions of the South of Russia.

This paper describes an in-situ experimental technique to study of ceria nanocatalysts by using X-ray absorption near edge spectroscopy XANES. This technique allows us to determine Ce3+ concentration inside ceria nanoparticles in the course of catalytic reaction based on the comparison and divergence minimization of the Ce L3 XANES spectrum of the ceria nanoparticles under catalysts (atmosphere, temperature) with a linear combination of two independent components corresponding to spectra of Ce4+ ion of the CeO2 structure and Ce3+ ion of the theoretical Ce2O3 structure. The calculated weight ratio determines the Ce3 + concentration in the sample during the catalytic reactions.

The problem of optimization of thick-walled sphere loaded by internal and external pressures was solved. The essence of the method consists in the variation of the modulus of elasticity. The problem of finding the distribution of the characteristics of material in which the stress state is given, is called the inverse problem. The idea of the inverse method was proposed by academician of RAACS prof.  V.I. Andreev. The analytical dependence of modulus of elasticity from the radius at which the calculated stress on the strength theory of Mor is constant throughout the thickness of the shell was found. This shell will be equally stressed. If the strength characteristics of the material do not depend on the modulus of elasticity it will also be equiresistant. By creation of indirect heterogeneity we reduced the maximum tensions in 1.6 times. It was also shown that in the case of a centrally symmetric problem the second theory of strength is a particular case of the strength theory of Mor.

The problem of manufacturing technology heterostructures pezofaza - metal considered in the article. Complexity consists in the fact that during the removal of the polymer in the system at low temperatures are formed porous layers, formed powders separated metal layers, having island macrostructure. One way to solve the problem - reducing the firing temperature heterostructures. Proposed to decrease the sintering temperature by using of functionally active glass-phases. Reducing the sintering temperature of products also allows to replace platinum electrodes inexpensive silver-based alloys. Obtained by solid state reaction method of piezoceramic material has a low sintering temperature (980 ° C) and high electrical parameters. Found that not only the proportion of the vitreous mass, but also their qualitative influence on the properties of piezomaterials

The technique of the geometrical analysis and the analysis of force loading of combined drills with the replaceable multiface plates is offered in this work. This technique is allowing to determine geometrical parameters and specific force loadings in each point of a plate’s cutting edge taking into account its orientation in the drill case. Application of this technique allowed to establish the reasons of the drill’s low durability. The offered technique allows to design drills from the minimum unbalanced radial component of cutting force which increases its working capacity and the processed holes quality. New designs of combined drills both with two, and with three replaceable multiface plates are offered in this work. The durability of this new drills is increased by the plates mutual turn for the minimization of an unbalanced radial component of cutting force

In the context of updating the formation of a common Eurasian space is particularly important to study the problem of realization of economic interests of economic entities operating within the system of relationships. Same interests of big business, in this case, play a special role , as it is large business structures , acting as actors of economic activity, are able to set new trends in the development of the economic environment , having sufficient capacity to be able to influence decision- government authorities of administrative decisions. Formation and development of a common Eurasian economic space requires the definition of " growth points" further relations between the states to set foot on the path of integration, and that the organizational form of big business can become a support for building a new system of economic relations. Integration processes in Eurasia based not only on increasing trade between the member countries of integration, but also on their complementarities , formed naturally as a result of centuries of economic cooperation and based on the economic interests of the largest multinational corporations or associations like them , specifying the vector of development of a single economic space. In turn, this single economic space opens up new possibilities for the realization of the economic interests of economic entities , especially for major actors in national economies. This article discusses the main directions of the interests of big business, represented by transnational corporations in the new economic conditions .
