Finding of small concentrations of various gases as an important task for the environment and for the industry. In this paper, investigated gas-sensitive properties of the films of graphene on silicon carbide to NO2 and vapour C2H5OH. The principle of operation of graphene sensor based on the change of electrical conductivity by reason of adsorption of gas molecules. Temperature dependence of the gas desorption from the surface of graphene is obtained. Mode of getting graphene films with the best gas sensing characteristics is defined. The obtained results suggest that graphene is a promising material for gas-sensitive sensors

In article gasdynamic approach for the solution of a task on heat distribution in simple gas pipelines on the basis of consideration of a current of gas in a laminar mode is considered. The objective is solved by means of research of system of the equations of work of extending gas taking into account an assessment of difference of temperatures at explosive decomposition of a working product. Classical approaches to research of distribution of heat in a simple cylindrical pipe are thus taken as a basis the main dependences characterizing both full, and the current work of a working product by means of correction coefficients and a ratio of temperatures of heating of walls Are presented. Connection between pressure is established at different weight ratios of gas. The specified approach can be used as a technique of model research of gasdynamic processes taking into account a thermolysis in gas pipelines.

It is noted that the services sector in the Rostov region isn't always accompanied by due quality and availability. Major factors which will affect dynamics of development of a services sector are defined. Dynamics of volume of paid services in subjects of the Southern federal district is analysed. The conclusion is drawn that the greatest possible ensuring requirements of the population of the region of the Rostov region in services of high level demands the unconditional solution of actual tasks which are also presented in work.

The paper considers arbitrarily supported arbitrarily loaded reinforced, beam with an aggregate of bimodulus of elasticity material. Formulas for determination of the tangential stresses arising in the aggregate, subject to the reinforced elements. Formulas are obtained for principal stresses occurring at an arbitrary point in the aggregate, as well as the equation for determining the point where major stresses reach extreme values. Are terms of strength as the classical theories of strength, and strength criteria applied for calculation of constructions made of bimodulus of elasticity material.

The influence of manganese nitrate impregnating solutions concentration and temperature dynamic viscosity, the wetting angle, interface “porous tantalum electrode - solution” free surface energy and the impregnation degree of porous tantalum anode was researched. A quantitative characteristic of manganese nitrate solution application on porous tantalum anode of solid-electrolyte capacitor during the process of impregnation was defined and work of adhesion and cohesion was calculated. Thus increasing of solution concentration above 42% wt brings to sharp growth of surface tension and so work of cohesion is increased but carriers impregnation is fallen. The most effective impregnation is realized at concentration 27% wt. This fact corresponds to best value of tantalum anode capacitor free surface energy. So using received data we are able to estimate optimal conditions of impregnation and wetting process by nitrate magnesium.

Principle of operation of a Turing machine and its variations, including finite automata, is to read the data tape; such an organization is a direct analogy with the coding information biopolimers, wich in turm served as the basis for the creation of several DNA-based computers. Computer input device in the form of O-DNA created before, however, the input and output demanded difficult reactions, each of which require human supervision.
