The article describes the methods of forming the program of technical and economic feasibility of reconstruction. The program is based on the technical and economic calculations which justify the need for its development. It is important to take into account the technical and economic indices which provide a minimal amount of construction works. During the development of technical and economic parameters, it is necessary to take into account the organization of construction, the terms of energy saving, heating, water supply, drainage and industrial waste water, human resources, the environment, the effectiveness of capital investments. All questions are considered for the perspective of the development of science and technology.
Keywords: site renovation, technical-and-economic indexes
Stability of sensors on the basis of inorganic oxide materials is one of the primary goals by working out of atmospheric air control devices. In this work long-term stability of a sensor response on the basis of the SiO2SnOxCuOy material to carbon oxide (II) exposure in a range of concentration 1-100 ppm is studied. It is shown that the sensor response differs high stability and reproducibility. Continuous heating within 21 days to working temperature (350°С) influence its value negligibly.
Keywords: stability of a response, sensor, carbon oxide, material of structure of SiO2SnOxCuOy.
We have investigated electrical and gas sensitive properties of gas sensor based on carbon nanotubes (CNT) and carbon nanotubes modified by metal oxides (such as tin oxide and silicon oxide). Also we have find out that modification of CNT by metal oxides helps to improve film`s adhesion to substrate, decrease electrical resistance, recovery time, working temperature , enhance gas sensitivity in comparison with sensitive elements based only on CNT or metal oxides. Moreover experimental results showed that properties of composite material depend on concentration correlation of solutions. As a result we can get highest sensitivity of sensor element by choosing optimal relation between concentrations of solutions.
Keywords: Сarbon nanotubes, modification, tin oxide, silicon oxide, gas sensor
The algorithm of the research, including the technology of making the mycelium film on the resonator of bulk acoustic wave and gas medium with the given concentration was developed. As a result of the investigations the sorption sensitivity of extracts of the higher shiitake mushroom mycelium to the fume of volatile liquids and gases (acetone, ethyl acetate, formaldehyde, chloroform, acetic acid and hydrochloric acid, hexane, 10% aqueous ammonia) was studied. The study has shown that there are the processes of making the mycelium films, which keep the initial values of the resonant frequency and the quality factor of the resonator after moving off the fumes or gases. This work has shown that the mycelia films are very promising as a new material for gas selective coatings of electro acoustic sensors.

The article covers the period from XVII to XIX century in the development of art education, when it loses its elitism and becomes massive. Identifies three major trends that have influenced the formation of pedagogical training bases of graphic activity and color in professional artistic training: academic training system, physics color and secondary school. The period and the basic principles of the formation of European and Russian art training. Determined by the stage of the formation of the world system of artistic training.

Development of urban areas, especially Rostov-on-Don, which is one the largest city of the south of Russia, should be based on a comprehensive assessment and analysis of the structure of housing stock and engineering services, which provide all types of resources for the city. Research of the structure of housing stock, analysis of residential and private housings, municipal and business buildings, information on the territorial distribution of these objects with reference to the topography would allow to create a reliable information base for the development of district heating schemes. Housing stock of Rostov-on-Don was ranked by the year of construction, number of floors and material of the wall. The article assesses the providing of municipal and business buildings, kindergartens, schools, institutions consumer services, culture and sport institutions.
