- Authors:
- R. E. Dashko
- I. V. Alekseev
Drainage water formation of the Yakovlevsky mine (Yakovlevsky deposit, KMA) is considered, as well as the features of its discharge to soak away and thereto related ecological issues. Ways of drainage water treatment are presented. The particular focus is given to the project of its disposal in the high-head Lower Carboniferous aquifer using injection methods. Negative effects of this measure and nature of its impact on the water-protective layer, determining safety of mining operations, are stated.

- Authors:
- Vega Milton
This paper describes the results of a study of gold from placer El Monigote, located in central Argentina in the north-east of the province of San Luis. Gold from this placer deposit has weak roundness, lowpower, high-grade rims and a grade of gold (close to 700 ‰) in the center of the gold particles. This indicates a single gold source which is located in a few kilometers north-west of the placer deposit El Monigote, which is likely related to the volcanic belt.

It is widely known that the processes of ore concentration have large part of operating costs for ore processing at the concentration plant. Often processes of crushing and grinding of raw materials account more than 70 % of the total spending. The aim of the optimal mineral processing is to decrease these costs, one solution of this problem is to preconcentrate raw material, which allows to withdraw from the further processing more than 80 % of the material, which doesn't contain valuable component, or has its dumping grade.

The paper presents a description of content and structure of the associative-verbal field «rest», representing a significant fragment of the world picture reflected in the Russian lan-guage. The present study brings out the semantic content of the lexeme «rest» on the basis of Russian glossaries. The content of the associative-verbal field «rest» is also analyzed on the basis of the «Russian associative dictionary» (Тhe editorship of U.N.Karaulov. Moscow, 2002) and on the basis of the free associative experiment, which was held in 2011-2012. According to the findings offers a segmentation of the associative-verbal field «rest» using differentiation on the basis of spatiotemporal features.

It has been demonstrated, that cylindrical probe in anisotropic plasma allows to measure only the even components of the electron velocity distribution expansion. For the first time the method for determining the odd moments of the distribution function by solving a system of ki-netic Boltzmann equations, connecting the even and odd moments ( f 0 , f 1 ); ( f 0 , f 1 , f 2 ) etc. has been developed. The method was tested in plasma of low-voltage beam discharge in helium. The experimental probe I- V traces for different orientations of a cylindrical probe with respect to the axis of symmetry of the plasma has been obtained. The moments of f 0 and f 2 has been cal-culated, f 1 moment is defined by solving the «vector» kinetic equation. The accuracy of f 1 calculation controlled by coincidence of calculated and measured values of discharge current. Theoretical and experimental values are in a good agreement.

This paper deals with the further development of the probe method for the investigation of the anisotropic plasma. The theoretical basis of the method for determining the full electron velocity distribution function in the mirror-symmetric plasma has been developed. For probes of different geometries the analytical expressions, which connects the second derivative of probe current with respect to the potential with the multipole moments of the electron velocity distribution function has been obtained.

- Authors:
- N. S. Pshchelko
- A. S. Poll
- D. O. Repetukh
In this work a device for measurement at a constant voltage of the basic electric characteristics of high-resistance dielectric materials and products from them – their electric capacitance and resistance – is developed. The principle of work of the device is based on use of transients in connected in sereies elements having electric capacity and resistance. In the electric circuit of the device the mosfet with high entrance resistance is used. Possibilities of practical use of the device for measurement of surface electret potential, for rejection of potentially unreliable condensers, for diagnostics of corrosion of metal under a pro-tective dielectric covering are considered, etc.

Experimentally the effect of adsorption and chemical properties of the metal filler (Al, Ni, Cu) on the value of the integral index of friction of lubrication tribosystem was studied. The basic relationship between the reactivity (during oxidation), hydrophobicity of the modified metal powders and tribological properties of lubricants based on them was determined.

It’s experimentally proved innovative methods of nanometric regulation of surface properties of metals, fillers and lubricants, as well as the results of testing oil-based lubricants on I-20 with various solid additives (on Al-, Cu-, Fe- base) at the nodes of the transmission oil refining equipment. By improving the antifriction properties of lubricant service life is increased by 40-80 %.
