The kinetics of the electrodeposition of zinc to the steel base of the sulfate electrolyte supplements with synthetic surfactants was studied. Found that at potentials more positive than the equilibrium value the process of pre phase zinc deposition. Additives synthesized organic compounds adsorbed to the surface of the electrode at its cathodic polarization, increasing of overvoltage process. The adsorption is in the range of 0,5•10-7 to 2,6•10-5 mol/сm2.

The paper studies the possibility of quantitative processing of the GPR data for determining the dielectric permittivity and conductivity of a medium (soil samples). Experimental studies are made using radargrams of soil samples with specified values of moisture and conductivity. New methods of quantitative processing of radargrams are proposed in this work to determine the dielectric permittivity and conductivity of soils. The methods were successfully tested on various sections of Russian railways net.

"Is analyzed the need for the investment of capital, optimizing selection most effective measures, for the reduction of technogenic action, to an improvement in the prirodokhozyaystvennoy situation. Worsening in the state of natural environment definitely requires the additional investment of capital, which draws the rise in price of production and as a result reduction in production efficiency. The tasks of the economic and social development of society must be determined taking into account ecological factor, i.e., taking into account rational use of natural resources. A substantial change in priorities and purposes of the economy of Russia, all branches and its separate sectors is required for this. In this context to the foreground are advanced effective measures for environmental protection in the process of the prirodokhozyaystvennoy activity, which correspond to the concept of steady development.A29 It is expedient to correct the taxation of profit taking into account the profitability of nature-conservation measures, effectiveness of its use with the solution of other social problems, meant both for the society, and for the ecology as a whole: investment tax credits with a considerable decrease or the cancellation of percentages for the use by them; the priority crediting of the subjects of the economy, who inject the best technologies of taking nature-conservation measures; the compensation for the part of the interest rate on the credit due to federal dollar (to 50%). The introduction of innovation technologies in the formation of the system of control of functioning and realization of nature-conservation measures, is the most important tool of an increase in the competitive ability of regions and companies under these conditions.

The results of computational experiments to determine the characteristics of the porous piezoelectric ceramics based on the methodology, including the effective modules method, simulations of representative volumes on a simple random method and the method of Witten-Sander, finite element method to solve static piezoelectric problems for heterogeneous composite media and the accounting of inhomogeneous polarization near the pores are presented. A comparison of the results of computer simulation with the known experimental data for the porous material PZT-4 and its analogs is realized. It is concluded that the accounting of inhomogeneous polarization in the vicinity of porous provide the better agreement between numerical results and large number of known experimental data. Thus, for most effective constants the smallest errors are obtained for a representative volume of the porous piezoelectric material, constructed by Witten-Sander method.

The coloration centres (CC) in crystals of rear earth gallium garnets (REGG): Gd3Ga5O12 (GGG), Gd3Sc1,6Ga3,4O12 (GSGG) и Nd3Ga5O12 (NGG) obtained by Chohraljskiy method, were investigated by methods of optical spectroscopy and spectral analysis in the wavelength range of 0,2-0,87 microns. In the case of keeping the samples under dark conditions, unstable CC were formed in the crystals of GGG and GSGG. The absorption maxima are at λmax1 = 0,243 m and λmax2 = 0,275 m at concentration of N ~ 1018 cm-3. It is suggested that the observed enlightenment is caused by the recharging of growth defects and occurring the energy levels in the band gap of garnets. It appears that these CC correspond to centres of O- holes, originated from gallium vacancies V3-Ga 3+ in tetrahedral and octahedral nots which form near clusters of [V3-Ga 3+ - V2+O2- ]
