  • Development of technology of receiving high-sensitivity gas sensors on the basis of zirconium oxide for hybrid sensor systems

      In this work the technology of receiving high-sensitivity gas sensors on the basis of zirconium oxide is developed for hybrid sensor systems. Laboratory samples of sensors of gas on the basis of zirconium oxide are made with use sol-gel method. Gas-sensitive characteristics of samples of sensors in relation to nitrogen dioxide are defined: limit of detection and factor of gas sensitivity. The received gas sensors will help to determine approach of an attack of bronchial asthma some hours prior to its beginning by level of an oxide of nitrogen in exhaled air of the person.

    Keywords: hybrid sensor systems, zirconium oxide, bronchial asthma, nitrogen dioxide

  • Stylistic features of eclecticism in the central part of the city of Rostov-on-Don at the turn of XIX - XX centuries.

    The article is devoted to the peculiarities of eclecticism in the central part of the city of Rostov-on-Don at the turn of the XIX - XX centuries. The Russian architecture in the years 1840-1850. prevailing eclecticism. All the variety of its variants is reduced in the Russian architecture in two varieties: the first of which dates back to the tradition of a warrant (neogrek, Renaissance, Baroque, Rococo, pampeyansky), and the second - to the non-classical heritage (Byzantine, Russian, Gothic, Romanesque styles). In Rostov architecture became widespread both varieties. This was facilitated not only the diversity of life in the city, the intensive development of trade industry, generating a variety of new types of buildings, but also the technical progress by which the means of production have changed.

  • Particular style of Constructivism as an example of the historical center of the city of Rostov-on-Don

    The article is devoted to a brief presentation style features Constructivism in the city of Rostov-on-Don. The construction boom in the city begins with the 1920s, a new style of Constructivism, had already fully declared itself in the capital. In the early 1930's. architectural development in Rostov took the path of development of the principles of the avant-garde. The very principles and forms of avant-garde come to the Rostov practice with some delay - as a kind of well-established tradition, continuity of development projects in Rostov architects

    In 1945, the Chairman of the Committee on Architecture AG Mordvinov announced seven conditions under which you can create the city.
    In 1945, the development of the urban plan of rebuilding the city of Rostov-on-Don was appointed academician of architecture VN Semenov.
    In 1949. master plan was finalized at the construction site.
    In general, the basic idea of the architect was executed. Among the fifteen cities prone to restore the city of Rostov was restored in all seven conditions put forward by the Chairman and the Committee for Architecture AG Mordvinov, projected architecture academician VN Semenov and given a reality by means of the chief architect of YA Rehbein."

  • Electrochemical titanium oxidation in electrolytes on the basis of glycerin with high water content

    The titanium dioxide synthesized by an electrochemical method is a perspective material for use in solar elements and catalysts of cleaning of water and air environments. Regularities of electrochemical synthesis of titanium dioxide in glycerin dilute solutions (1:1) in the presence of ammonium fluoride at 2-14 V are investigated. Mathematical scheduling of synthesis process according to plans of first order with use of the complete three-factorial experiment is carried out, the adequate regression equations for formation processes of a titanium dioxide in the field of potentials 8-14 V are received. The electron microscopy method proved porosity of synthesizable layers of titanium dioxide. Water content influence in electrolyte on the speed of electrochemical process and potential size influence on titanium dioxide materials yield is established. It is shown that under the chosen electrolysis conditions electrochemical process is accompanied by the considerable chemical disolution of a titanium. Electrochemical processes in water containing glycerin are investigated by a cyclic voltammetry method. It is established that at electrochemical oxidation of Ti in water containing glycerin (1:1) porous TiO2 with a materials yield no more than 25% is formed.

  • General principles of existing strategies reconstruction of the housing stock was built by the project of the first mass series

    Describes three стратегиb housing reconstruction of the first mass series: the radical, complex, a conservative. Implementation of the existing strategies is impossible without the development of additional organizational and technological measures (OTM). When developing OTM should be based on the division of the whole complex of works on reconstruction of the separate stages and associated volumes, which can be performed independently and at different times. In a basis of an element-centric approach to the reconstruction should be based on the principle of economic feasibility and interest of all participants in the process of reconstruction. OTM in поэлементном approach to the reconstruction of forming a system of relations, rights, duties and mutual guarantees of the participants, secured by means of linking the investment cycle for reconstruction into a single organizational-technological building system (ОТСС)
