In this article is reviewed the nature of organic hybrid nanocomposites. Promising directions in the field of organic hybrid nanocomposite materials will be methods for the synthesis of multicomponent materials, as well as the type of "net net" and "host-guest". The fundamental problem with the chemistry and physics of nanocomposites is dependent "structure-property". Solving this problem will move from research materials to their purposeful design.

The characteristics of the migration processes in Russia and the Republic of Karelia. Shown that research in the field of promotion of the Russian language and Russian as a foreign language as a native language in Russia and abroad have seen in close conjunction with the analysis of migration processes associated with the need for teaching Russian adapting foreign citizens in the country. The analysis showed that the transition to a "quiet" conditions of a market economy after the 2000 cross-country movement of labor with Russia intensified: the capacity of the Russian labor market and the increased mobility of Russians led the growth of migration flows, Russia as a whole remains a "host" side - the number of labor migrants in Russia considerably exceeds the number of Russians traveling to work abroad. Such a situation is typical for the Republic of Karelia. A comparison of labor migration on vocational qualification groups

Keywords: migration, Republic of Karelia, Russia, Russian language.

The atomic structure of bimetallic nanoparticles of Pt-Ag composition, which are the part of metal-carbon electro-catalysts PtAg/C, is studied by means of EXAFS spectroscopy using the suggested technique. These materials have been prepared by methods of consistent and simultaneous deposition of Ag and Pt atoms from aqueous ethylene glycol solutions of their salts with subsequent acid treatment. The values ​​of the structural parameters of the near environment of platinum atoms are determined. The nature of the distribution of components in nanoparticles is established. Cluster models of nanoparticles are constructed. The fraction of Pt atoms in the working shell and its dependance on preparation methods in each case are determined.

The article highlights the issue of conservation of water and energy resources, the dependence of its decision on the environmental responsibility of business entities and tactical goals towards environmental management.  Also the essence of the work carried out in the production of ammophos is described (Hydrometallurgical plant, Lermontov town), which is a good example of solving one of the many tactical tasks in the direction of environmental management. Specific purpose of the work was to identify the savings reserves of energy and natural resources. The application object of the study is the energy-intensive production of ammophos (fertilizer complex of nitrogen and phosphorus compounds), in particular the boiling-down of ammoniated pulp. The load decrease by evaporated water by 75% is achieved the implementation of technical solutions in terms of sealing pumps work (replacing inefficient crevice seal on a metal face seal) installed on the circulation line of ammoniated pulp. This reduces the coolant flow for boiling-down of high pressure steam and drinking water saving, which is the raw material for the production of fluid. Ecological and economic efficiency of the proposed solutions is confirmed by the calculation of the expected technical and economic parameters, performed on the basis of data generated in monitoring: coolant saving - 3039 Gcal / y; 2430 rubles / g; drinking water saving - 11,477 rubles.
