Recent advances in chemistry and technology of nonisocyanate polyurethane (NIPU) materials based on cyclic carbonate oligomers are reviewed in this paper. Reaction of the cyclic carbonate and amino groups results in β-hydroxyurethane fragments with specific properties. Primary attention is given to the hybrid materials that contain epoxy and acrylic compounds, especially materials based on renewable raw materials. Hybrid organic composites comprising of silanes are also considered. An overview of the recent publications in this field is provided with a more detailed description of achievements by the authors and their corporate employees. The use of NIPU materials as coatings, adhesives, and foams is described.

The factors affecting the formation of the intellectual property in economic structures. It is shown that the most important of them are: business entity formed in an innovative atmosphere, staff training and the ownership of the methodology of inventive problem solving, formed the scientific and innovative school, the presence of structure responsible for the protection of intellectual property, participation in grants initiated by the Ministry of Education and Science of Russia (in vol. h. performed under the Resolution of the Russian Government and aimed at the integration of universities with the production), access to databases of scientific and technical information.

the article shows that recycling is being paid more and more attention in Russia and abroad, as the important factor of resource saving and solutions of ecological problem. It’s mentioned that despite the realized research and certain implementation experience, a lot of problems is still not solved. Special attention’s drawn to the acuteness of the problem of production and consumption waste recycling, the search and implementation of new sci-tech, business and also legislative solutions in this field

Keywords: nuclear energy, production waste, recycling, solid radioactive waste, ecology.

The authors, based on the study of historical materials, analysis of architectural solutions constructed buildings, as well as the design of local architects, associate a symbol, Nalchik - a Shoe with his name. On the basis of various examples show the use of the symbol of the city - horseshoe as an architectural element (image) buildings and structures (entry sign, in Nalchik, the architect W. H. Carter; project stables Nalchik Hippodrome, architect W. L. Aliev; the reconstruction project of the shopping center "Nalchik", architects design Studio "KabBalktelecom"; project Newsstand, in Nalchik, the architect W. L. Eliev). The authors emphasize a pretty bad use of the symbol of the city horseshoe in the reconstruction of the shopping center "Nalchik": designed space-sham construction on the corner of the building facing the intersection of two main avenues, Nalchik, etc. to them. Kuliev, etc. to them. Lenin. In the final part of the article the authors recommend local architects often prinosit national motifs (based on the rich national culture of the indigenous peoples inhabiting the Republic) in the development of their projects, and to use the symbol, Nalchik is a horseshoe, as the architectural tectonics in the projected buildings.

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.

Keywords: nanocomposite sol-gel technology, synthesis, nanoparticles.

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.

This paper considers basic element of device of energy storage which is a piezoelectric generator (PEG) of cylindrical form with the attached inertial mass. A finite element modeling of the device operation is carried out during active load in the external circuit. The main purpose of the operation is to compare the output potential and frequency characteristics of the device known in the literature models of systems with concentrated parameters. On the basis of these models, we can receive the analytical dependence of parameters of PEG with its geometric characteristics and mechanical properties of the used materials. However, the question of the range of applicability of these formulas is still open. In this paper, based on the numerical analysis of finite element models of PEG in package ANSYS, we obtained comparison with the analytical formulas that show the values of some parameters of simplified models and set the boundaries of their applicability.
