The article is devoted to one of the urgent problems of the present-day Russian reality that is the family institution transformation which progresses in the network of the crisis of traditional family and forming the present-day family pattern. This period is characterized by forming transformational space in domestic and conjugal sphere that is presented with coexistence of traditional and new forms of domestic relations. What is in store for Russia and its diverse in ethnocultural and sociocultural respect regions? What pattern of family is going to be prevailing in Russian society in the nearest future? The author is trying to answer these questions in this article with using the synergetic methodological paradigm of investigation.

At present an important role in solving energy conservation problem is assigned to thermal pumping plants (TPP). Using processes of evaporation and condensation of easily boiling liquid circulating in the system they extract low potential heat from environmental objects and provide heat supply for buildings, constructions, greenhousee and so on. Artificial sources of low potential heat for TPP of different capacity can be, for instance, ventilation air and exhaust gases, circulating and waste water,ground. Energy efficient reasonability of TPP use in the system of water disposal for the town of Novocherkassk in Rostov region is considered. Calculations indicate that there is a technical potential to replace a boiler house operating on expensive gas fuel and emissing into the atmospere more than 850 t of carbon dioxide - greenhouse gas - with ecologically clean TPP, one of which uses heat of waste water and the other - heat of ground.

The article analyzes the population dynamics, habitat settlement in the Rostov region of Ukrainians and Armenians, representing two major regional diaspora. We study their complex demographic and spatial relationship in the post-war decades, and in the post-Soviet period. The reasons rapidly declining regional Ukrainian community in the late twentieth century - beginning of the XXI century. Predicted the most likely scenario, the demographic dynamics of the two diasporas in the coming decades, examines the role in this process of modern Ukrainian crisis caused by the influx within the scope of large numbers of refugees.

Keywords: Ukrainians and Armenians, regional communities, and the number of resettlement, ethno-cultural structure of the Diaspora

The article describes the research of thermodurability of glass-carbon - one of the most promising carbon materials used in the production of luminophors and semiconductor materials, optical single crystals, etc. The aim of this work was to study the behavior glass-carbon in the course of thermo-cyclic testing. As a method of diagnostics of the birth and development of micro-cracks was used by the reception of signals of acoustic emission. It is shown that at heating in the samples glass-carbon there was a strong movement of dislocations in thermocyclic effects ,recognized in the signals of acoustic emission. As the number of pulses when heated above, than during the cooling of the sample, it is evidence of the accumulation of damages in the structure of the cyclic thermal processing glass-carbon samples. It is established, that the curves of the accumulation of defects at the pulses of acoustic emission, differ on the stage of heating and cooling. Proposed to use the curve of the aggregate accounts of acoustic emission pulses as a possible harbinger of destruction when heated glass-carbon of the product.

Keywords: acoustic emission, electrodeposition, the activity of the AE, the remote control.

Based on the calculations presented in numerical and graphic kind, identified the following areas of heating polymer: uniform heating, regional zones of thermal influence of insulators. Heat-affected zone is characterized by depth and temperature of the contacting surfaces. The thickness increase of insulators over a certain value does not change the zone of thermal influence of insulators, which allows to speak about effective from the energy point of view of the thickness of the insulator, the excess of which increase energy consumption, time of heating of the polymer.
Conclusion is made according to result of the study about the necessity of the presence and settings termoisolations when building technological processes electrothermic of polymers.
