    [article]
    Summary

    The aim of the study is to develop scientific and practical principles of implementation of energy saving heat pump technology for heat and cold supply to residential, public and industrial premises on the basis of alternative and renewable sources of energy. One of the effective methods to generate heat from groundwater by means of heat pump technology is the use of wells for consolidation of heat exchange elements produced by drilling. Fundamentally new innovative method of making wells is electro-hydraulic drilling. According this method an electrical energy transformed into mechanical energy of shock waves that can break up rocks directly in the bottom hole. This paper describes the results of a study of the electric hydro-pulse effect on hard and super hard rock minerals.

    [article]
    Summary

    Modern development of power system is characterized by the decrease of using expensive liquid fuel which is a valuable raw material for the oil refining industry and the increase of using solid fuels. Stocks of high-quality coal deposits are exhausted due to increase in a share of solid fuels. Besides, there is deterioration in a quality of solid fuels extracted by mining method. Transition to the development of powerful coal deposits mined by open way and the use of it as fuel for power plants and other fuel using devices are connected with certain difficulties. And mainly it is because of high cost and power consumption of preparation process for burning.

    [article]
    Summary

    Research of corrosion resistance of nanostructural nickel-titanium and his biomedical composite with Ta surface layer received by a method of physical vapor deposition is conducted. Samples were placed in mediums imitating physiological liquids, with рН from 1.68 to 9.18. 3 types of nitinol samples were used: in an initial state, after thermal (annealing) and surface mechanical treatment. The greatest release of nickel ions was observed in solution with the sourest environment and samples after annealing. Release of nickel ions in solution with composite samples wasn’t observed.

    [article]
    Summary

    Studies of structural and phase state of Be-Fe-Be three-layer system were conducted using Mössbauer spectroscopy method at 57Fe nuclei after krypton ions irradiation with energy of 280 keV and subsequent isochronous annealing. Under irradiation, a local concentration of beryllium atoms was observed in the subsurface layer of the layered system samples. This concentration causes transition of a substantial part of the Fe atoms in the subsurface layer from a magnetic ordered state to the paramagnetic one. Post-radiation isochronous annealing results in almost complete recovery of pre-implantation local concentration of components and restoration of structure of the irradiated subsurface layer. Presented in the paper experimental results show that the implanted krypton has a great impact on the phase state of the layered system, and they can be useful to better understand and predict the effects of the gas discharge in neutron fields on radiation effects in structural materials of nuclear and thermonuclear facilities.

    [article]
    Summary

    The influence of silver nanoparticle on the spontaneous and stimulated luminescence of rhodamine 6G molecules in aqueous solution was studied. It was determined that under laser beam excitation of the dye solution appears the stimulated luminescence which with increase in laser pumping transforms in stimulated laser emission and superluminescence. In the presence of silver nanoparticle all kinds of emission amplification and the lasing threshold contraction of both types of stimulated emission have been observed. When measuring the emission spectra of solutions for “reflection” superluminescence of rhodamine 6G was found.Dependence of the lasing intensity and the superluminescence intensity on nanoparticle silver concentration correlates with spontaneous fluorescence data.

    [article]
    Summary

    ZnO nanorod array were synthesized on sol-gel prepared ZnO seed layer over quarts substrates by hydrothermal method. X-ray diffraction results show that nanorods are the typical hexagonal wurtzite structure without any other new phase and preferentially oriented along the c-axis perpendicular to the substrate surface. The scanning electron microscopy (SEM) of the surface of the ZnO film showed vertical ZnO nanorods with hexagonal crossection. The luminescence spectrum of ZnO nanorod array consisted of a narrow UV band and a broad band in visible region of spectrum and its temporal characteristics were measured.

  7. Kazhikenova S.Sh. THE ORETICAL EVALUATION OF PRESSURE AND VOLUMETRIC MODULES IN INORGANIC METALS SILICON, SELENIUM, TELLURIUM, GERMANIUM
    [article]
    Summary

    Based on the double-structured model of the melt with the cluster and atomic components with the involvement of the two mechanisms of thermal clusters’ decay, experimental and theoretical results on the structural states of the melts are interpreted. A possible explanation of the proposed two-structural model is in the neglect of the components of electron-ion interaction of the higher order than the second one. More over the inadequacy of pseudo-potential modification by means of the correction to the Hartee energy leads to the correct result only in the long-wave limit also. The given correlations allow us to calculate the compressibility of the melts. The theoretical calculated polyterms of the compressibility to selenium, tellurium, germanium and silicon are shown.

    [article]
    Summary

    The article is devoted to modeling electromagnetic systems which was carried out in a package of the applied ANSYS programs. ANSYS is universal program system of finite element analysis. Modeling and analysis in some areas of the industry allows to avoid expensive and long-lived cycles of development like “projection — manufacture — tests”. The system works on the basis of geometric element. Each type of elements uses values of material properties.

  9. Amochaeva G.P., Zakiev D.M. ANALYSIS OF ELECTRICAL FILTERS IN HIGH LEVEL LANGUAGE C + +
    [article]
    Summary

    Article presents a synthesis system of active electric filters on the basis of its mathematical models provided by linear transfer functions. Each filter is implemented to operational amplifiers, resistors and capacitors. All filter elements are linear, concentrated and invariant over time.The initial data for the synthesis filters are the cut-off frequency response model of dynamic links and angles of inclination to the axis (dB / decade). Initial data for calculation of filters are the nominal values of capacitors stored in the corresponding file. The developed system has the ability to expand at the expense of updating files that contain the concepts of unit cells of active filters and nominal values of capacitors.

    [article]
    Summary

    The paper presents the results of experimental studies to determine the drag forces and drag coefficient of two-bladed wind turbine based on the Magnus effect with smooth rotating cylinders in the range of velocities of airflow 4 ÷ 13 m / s. Dependences of drag forces on the flow rate of two-bladed wind turbine with rotating smooth cylinder at the diameter of cylinders is 5 cm,10 cm and the length of each cylinder is 20 cm were obtained. Universal dependences of drag coefficient of two-bladed wind turbine on the Reynolds number at the diameter of cylinders is 5 cm, 10 cm and the length of each cylinder is 20 cm were investigated. The results showed that an increase in Reynolds’ number leads to a decrease in drag coefficient since drag coefficient is directly proportional to the drag force but is inversely proportional to the square value of speed.

    [article]
    Summary

    The iterative model which allows on induced electro driving force (e.d.f.) is developed. Of an induction of a magnetic field can to calculate numerical values and to define a profile B(y) in in air gap of the electric car. On the basis of it is possible to calculate streams of a magnetic induction F along a ring contour on a stator. The model allows to calculate forces of mechanical coupling of a magnet (on a rotor) with a ferromagnetic material (on a stator) on the basis of calculation of ponderomotive magnetic volume induced forces. The design of the wind generator on the basis of use powerful disk magnets on the basis of an alloy iron–neodymium–boron is developed.
