  • "Construction of translucent roofs. Part 2. Innovative technologies and materials "

    This paper logically continues the first part of the work describing roof construction with the use of translucent materials. The analysis of the current tendencies in the construction of roofs for sports and entertainment facilities showed that the contemporary studies are focused on the development of sliding roofs and the most recent trends feature façade and roof coatings made of ethylene copolymer and tetrafluorethylene based (ETFE) film. This paper discusses the most prominent advantages of membrane cushion roofing in the light of the summary analysis covering the articles of foreign authors. It mentions that ETFE cushion roofs are also used to restore buildings and structures of historical significance. The paper goes on to suggest a new structure of sliding roof and describes the construction technology taking into account the experience of building ETFE cushion roofs.

    Keywords: sports, entertainment facilities, sliding roof systems, construction technology, ethylene copolymer and tetrafluorethylene based film

  • Black sea-Caspian region as the "Great game": the classification system analysis

    The object of system analysis is increasingly becoming a geopolitical constructs. The part of the system analysis is to focus on the classification aspects of the structural elements of such a geopolitical entity as the Black Sea-Caspian region. Classification analysis is focused on actors (players), initiating "the Great game" in the political field of the region. We propose consideration of the morphological (elementwise) of the Black Sea-Caspian region, followed by the ranking of "local" actors and building of the "crystal lattice" on a regional scale. For the study of actors we are propose to use additive and integrative approaches. First is to involve sequential consideration of three geographical sub-regions "Black Sea – Caucasus – Caspian" as sites of "place-action". The second approach comes from the impossibility of a clear definition of natural boundaries "of the Black Sea, Caucasus and Caspian basin", taken separately. The authors propose for the boundaries in a purely geographical sense to understand some of the transition area between environments and/or spaces with qualitatively and quantitatively different properties and parameters. Actually there is "overlay" above three sub-regions, their intersection, fact that "stay" of some States of this zone in several of these subregions.

  • Disposal of technogenic resources using microbial bioconversion

    Abstract: the Article is devoted to the problem of waste production during construction, operation and liquidation of coal mines of Russia. This work suggests that waste recycling technologies, including for reception of energy based on the modeling and system analysis of the biocenosis. The possibility of realization of innovative methods of processing plethodon using the biocenosis. Quite detailed questions transformation of industrial waste into energy through anaerobic bioconversion. As part of a description of the proposed methodology presents the results of field experiments and action program of recycling of materials at the stage of commercial operation. In particular it justifies the optimization of processing technology on the basis of the selection of the most active biocenosis of microorganisms. Theoretical developments are confirmed by practical data.

  • Simulation of the design activity diversification of innovative enterprise

    It is shown that one of the most important elements influencing the nature of development in the region is socio-ethno-cultural landscape. The study of its characteristics suggests a wide use of methods of social simulation. The purpose of modeling is to estimate the required parameters in conditions of uncertainty, both at the planning stage and during the current administration. Theoretical solutions to this challenge are based on the use of the principle of duality, when the production and analysis of missing information about a managed object, in our case about socio-ethno-cultural landscape, the system is in the process of governance. The duality of the models appears in their dual role as research (for monitoring characteristics of socio-ethno-cultural landscape and, at the same time as the reference models for the management of development in the region. Need of approbation and problem integration of methods of the system analysis, social diagnostics and social and mathematical modeling which will make new scientific methodology of research is shown. To solve the problem of this level is proposed for effective convergence of methodological knowledge in the use of total potential informational, cognitive, and socio-humanitarian technologies.

  • Improving the technology of municipal wastewater treatment with the use of the sorbent on the basis of surplus sludge

    In the framework of the given article shall be considered a negative impact on microorganisms of ions of zinc, copper and Nickel concentrations in the incoming wastewater to the wastewater treatment facilities of the cities of the Lower Volga region is unacceptably high, which inevitably reduces the quality of the purified water at the indicated metals exceeding the output after biological treatment is more than 30 times). Further, in the proposed article, we describe the results of studies aimed at disposal and treatment of waste activated sludge. The first attempt to use the resulting after biological purification of waste as a secondary raw material for the adsorption material, which retrieves the designated heavy metal ions from wastewaters prior to biological treatment, which allows further the activated sludge fully interact with other ions without losing their functions. As a result, after the biological cycle treated water at the indicated metals, meets the relevant standards.

  • Software of reliability technology process of centrifugal rotary finishing-hardening treatment

    In article reviewed advanced theoretical probability models of process quality formation quality of the surface layer in a centrifugal rotary process (CSO) details. Process CSO reviewed from the point of view reliability. Based on the results of theoretical studies were proposed the dependence of the influence of the main technological parameters centrifugal rotary finishing and strengthening treatment on the roughness of the processed surface, the depth of the hardened layer and the degree of hardening. Analysis of the technology processes CSO let to identify the factors exerting a dominant influence on the productivity and quality of processing. Conducted calculations of the influence the tolerances of the main quality parameters of the surface layer and technology modes centrifugal rotary processing of centrifugal rotary treatment on the magnitude of the coefficients offset instantaneous dispersion and stock accuracy which characterize the reliability of technological processes centrifugal rotary process. By results of calculations were constructed charts. Taking the presented methodology you can choose such a combination in choosing technological processes centrifugal rotary processing what will ensure the required quality of the workpiece.

  • Electronic scientific journal: systematic goals and assessments

    A modern trend of scientific publications development shifts toward the network environments to an even more considerable degree. In practice, the new culture of the scientific publications is forming on basis of the global and mini Internet-platforms. The discussion of the comprehension experience and overcoming the different rating problems is suggested in the context of a science webzine “Engineer bulletin of Don”. It is observed that as the position of science webzines becomes stronger in the common space of the science magazines, there is a tendency to revising their evaluation criterion. Besides, the implementation of rates or coefficients prevails, the applicability of which relative to the science webzines is exogenous, i.e. it disclaims the aims of the science webzines. The application of restrictions, worked out within the framework of the traditional paper book-printing technology, is indicated to be unpromising. A new level of the science environment systemacy is suggested to be supplemented with the formalization of scientific evaluation rations, already existing and successfully maintained de facto, within the framework of the webzines – the Internet-platforms.
