  • Erecting multistory buildings with monolithic reinforced concrete slab floors by using of precast large-sized spatial structures

    Introduction. The present invention generally relates to construction elements for erecting structures, and also to methods of erecting structures with the use of construction elements. Construction elements for erecting structures are conventionally flat elements, which are assembled at a site of construction for erecting a structure. Such flat constructions elements cannot be too wide because their transportation with the use of conventional transportation means is not possible. It is therefore necessary to use the construction elements with reduced width to allow their transportation, or to produce wide construction elements at the construction site. It is therefore believed that it would be advisable to improve existing construction elements and methods for erection of structures with their use. Result. The new technology of construction, based on the use of precast reinforced concrete large-sized spatial structures with variable geometry, allowing transportation without the special vehicles. After truck shipment and restore the geometry, structure is mounted to final position. As a result of the only one mounting stage, load bearing and (or) enclosure structure, permanent formwork of a monolithic slab floor are erected. The proposed technology is confirmed by the author’s priority (Patent № US 8,615,967 B1 / Dec. 31, 2013) Conclusions. Patent search report and the actual fact of the U.S. Patent allow us to draw a conclusion on feasibility and prospect of new technology.

  • "Polycrystal temperature dependent semiconducting resistances of coaxial type and starting devices based on them "

    Nowadays the rolling stock is equipped with electric drive of high power. Frequency turning regulation, motor protection from overheating and limitation of starting currents are made with the help of semiconductor elements. For reliability improvement of starting and regulating facilities it is reasonable to use low component count. Running through regulating facilities current decrease simplifies electric circuit configuration. The authors propose to use thermal resistors as main elements. In the article the authors examine construct specifications of polycrystal temperature dependent semiconducting resistances of coaxial type and their advantages. There are some theoretical propositions which describe the work of thermal resistors and also some algorithms for synthesis of coaxial type starting devices. The authors made mathematical modeling for starting devices of different types based on thermal resistors. In the article there are some graphical dependences describing starting process.

  • Developing french for specific purposes self-study support materials

    The purpose of the research was to develop and implement self-study support materials to facilitate the French for Specific Purposes (FSP) curriculum implementation in mixed-speciality groups of engineering students. The context in which the course emerges and characteristics of mixed-speciality groups of engineering students are given in the paper.The authors hypothesized that such self-study support materials should be developed on the basis of active, student-centered learning and promote 21st century skills. Project-based learning was suggested as the main teaching method. Examples of students’ projects are given and the project stages are described. A blank report form was developed as a mean of project support.

  • Bioethics as an institutional mechanism of social control of modern scientific knowledge

    The place and the role of bioethics in the system of social relations and interactions are shown in article. The bioethics as the formed social institute creates social mechanisms of ethical control of rapidly developing biotechnologies. Its syncretic and multilevel character gives the chance of "maneuver" in development of moral positions and adoptions of moral decisions not only in difficult situations of application of biomedical technologies, but also in certain sociocultural, medical contexts. The author comes to the conclusion that from the point of view of the social relations and interactions the bioethics corrects tension in relationship of science and society, axiological mechanisms of regulation of this tension, ethical mechanisms of realization of medical practice, defining the borders of a moral choice and moral responsibility, it acts as social control of modern scientific knowledge.

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.

  • Energy conservation during treatment of sewage from populated area

    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.
