The measured spectra and orientation dependence of the X-rays emitted at an angle of 19/spl deg/ to the 500 MeV electron beam of the Tomsk synchrotron are discussed. The generated 27 keV radiation consists of parametric X-ray radiation (PXR) and diffracted X-ray transition radiation (DTR). It has been shown that the intensity of the DTR component of generated X-rays is much greater than that of the PXR.","PeriodicalId":250552,"journal":{"name":"Proceedings Third Russian-Korean International Symposium on Science and Technology.

It has been shown in previous investigations that in the case of a water medium a longitudinal component of EMF is prevailing and can be characterized by longitudinal current density or longitudinal intensity. The intensity of a longitudinal field depends on the following major factors: design of the armour and sheath of underwater cable; mode of cable line operation; method of cable laying; magnitude of grounding resistance of the screen and sheath on coastal substations; conductivity of water medium. All these factors characterize a longitudinal field not only in a normal operational mode, but also at short circuits. In the present work, as well as a normal mode of operation, stationary modes, external (in system contiguous to CL) and internal (between conductor and sheath in CL) short circuits, are also considered. Even though there is not enough systematic data on the influence of exposure time of a electromagnetic field on ichthiofauna, analysis of the field characteristics at times of exposure, determined by relay protection, can help in deciding on appropriate future experiments.","PeriodicalId":250552,"journal":{"name":"Proceedings Third Russian-Korean International Symposium on Science and Technology.

The outcomes of calculations of a position of a central axis of a gas plume for different values of number Richardson (Ri), describing thermal stratification of atmosphere are submitted.

The pictures of visualization are parsed and the experimental data on concentration \"of marked gas\" near to an earth surface are adduced. The satisfactory coincidence of the computational and experimental data is shown. Introduction Problem of protection of an environment, in particular of atmospheric air one of the major tasks of mankind. The main danger is represented by contamination of atmosphere by lets of industrial firms and power systems. The value of concentration of parasitic impurity in atmosphere in main is influenced with meteorological conditions, velocity of a wind, inversion of temperature. Therefore in the task of the forecast of carry and dispersion of impurity in air from continuous low sources, for example, pipes of chemical manufactures or smoke pipes of boiler-houses, it is important to know the possible forms of plumes and condition of their transformation (dispersion) in space. Generally atmospheric processes can be described by equations of the Navies-Stokes supplemented appropriate models of processes of turbulent carry [l]. However, as process in atmosphere uncontrollable also depend on large number factor to receive theoretical solution in general statement of the task predicament, At the numerical solution of the task it is important to give a qualitative and quantitative estimation of influence of parameters of a buoyancy, stratification and wind of a flow on basic performances of a jet which is flowing out from a point source of lets.

The way of estimation of characteristics of separate discharges within smaller sets was proposed. Protective coatings (composite materials), formed in processes of electrochemical microplasma synthesis, possess high. wear-, thermo-, erosionresistance and may be used for equipment protection in oil & gas extracting industry, machinery construction, textile industry and other. Emphasize on the search for practically perspective methods has led to a lag in elaborating of fundamental aspects. All these processes are realized under very high polarizations, it means, under conditions, far from equillibriwn even locally. Substantial role both in mass-transfer and creating useful properties of synthesized materials (coatings, films) is played by microdischarges and their sets, emerging at controlling parameters reaching undefined levels. Here we attempted to outline the opportunities gained and means of characterization of microdischerges and their sets. The term 'microplasma processes' means only the small sizes of discharges and presence of plasma component inside. Within this collective notion their are pointed out anodic and anodiccathodic spark, microark and ark processes. The common feature of the variety of processes is a stage sequence consequent realization of specific discharges sets and conjugate processes. Fig. 1. (a) shows voltage chronogram for anodic process. Sections II and I11 account for domination of spark and microark disharges accordingly, and small border area of 'rounded break' for their coexistance. In anodic-cathodic processes the coexistance of discharges lasts for a long time (section 2,3, fig. 1. b)) and one can highlight chronogram sections, dealing with sharp domination of one type of discharges (section 3\", fig. 1. c)) only using special current modes. Highlighting voltage chronogram sections, corresponding with certain type of discharges, helped to explain a negative slope of the 'formation curve' (chronogram) section (fig. 1. c), section 3\"). Information on stage sequence may be that foundation, on which the study of microdischarges and their sets may be based in connection with information on characteristics of formed and/or modified by them substantial-structure complexes, This connection is often not taken into account in a well-known to us literature on researches of microdischarges. Studies of effective characteristics of single microdischarges (as medium-statistic ideals within their specific sets) and studies of specific single discharges parameters (including within smaller sets) are perspective.
