US universities are leading the way in technology commercialization, while universities in Russia lag far behind. This paper discusses the best American practices, as well as the main issues of technology commercialization at the US universities. As an example, we consider the experience of the University of Maryland, College Park. In the next section, we turn to technology commercialization in Russia, where it struggles for several reasons. In this paper, we propose that Russia can improve its technology commercialization by studying the example of the leading US entrepreneurial universities and implementing proper procedures. And the important overarching point is that Russian universities need to improve their collaboration with industry, and they need to develop new standards of administrative, research, and business activity that will promote innovation and entrepreneurship. © 2015 Springer Science+Business Media New York Source

Examples of integrated use of geochemical and mineralogical techniques together with electroprospecting survey of the objects with a complex geological structure in Eastern Siberia are considered. Exploring by regional profiles of magnetotelluric sounding in the area of world-class Pb-Zn deposits Ozernoe allowed to map the deep structure, mineralogical and geochemical studies gave the possibility to forecast Au-Ag, Au-Ba, Au-As and Au-Mo-U mineralization in the territory. Local AMTS-profiling revealed flooded fault zone controlling intersecting auriferous quartz-vein bodies. Integration of AMTS, gamma-ray spectrometry and geochemical survey for secondary dispersion halos overlapped on the lake-marsh deposits territories enabled prediction of indigenous sources of alluvial gold-brannerite mineralization. Geological and geophysical studies of volcano-like Patom Crater and his structure showed his complex deep structure characterized by the presence of carbonaceous rock formations-potential generators of methane, permafrost zone of carbonate rocks under the crater is considered as a buffer for the phase transitions of methane hydrate methane and vice versa, which led to the excavation of limestone boulders on the surface the material cone and subsequent subsidence of its central hill.

By means of the technique of local analysis, the presence of a wide variety of tungsten and tungsten-containing accessories was first revealed in the composition of lithium-fluoric granites of the Far East, which represents a substantial similarity and regional peculiarity of these rocks. It was concluded that the tungsten accessory mineralization might be considered as an indication of the genetic relationship of the mineralization of the East Asian tin-tungsten zone to the Pacific rare-metal granites. © 2014, Pleiades Publishing, Ltd.

Seismic recordings of methods of the reflected and refracted waves contain information on features of a geological structure of the studied areas. This information is concluded in kinematic (arrival times) and dynamic (amplitudes) parameters of waves. In a method of the reflected waves for determination of elastic properties of the studied geological environment in the course of processing of records widely are used not only kinematic, but also dynamic properties of waves. In a method of the refracted waves kinematic processing is carried out generally. On productive kinematic cuts the provision of refracting borders and value of boundary speeds (without amplitudes) is, as a rule, represented. Dynamic properties of records are attracted only at a stage of correlation, definition of kinematics and the nature of waves. The way of receiving the method of the refracted waves dynamic coal mines at which values of amplitudes of waves characterize difference of elastic properties in an entry point of the refracted wave in refracting layer or an exit from it is offered.

The methodological bases for determining the energy resource of mechanical transmissions details for mining machines are considered. Based on the analysis of the accumulation of damage in metal gears, a method of estimating residual life of coarse-toothed wheels by periodically measuring the hardness of the surface layer of the teeth is justified. The regularities in change of hardness of coarse-tooth gear, conditioned by a change in metal strength properties that take into account the micro- and macromechanisms of plastic and elastic deformation, distortion of the metal crystal lattice with formation and movement of vacancies and dislocations. Experimental setup was built and the results of laboratory experiments are given related to the process of destruction of non-standard samples under different loads. Comparison of dimensions and hardness values of the sample allows concluding that a larger deformation corresponds to a greater increase in hardness, their limit value for the material being in the fracture zone. It is established that the detected changes in the local hardness occurs in areas of increased stresses above the limit of proportionality and the work of fracture forces attributed to dislocations density adjacent to the fracture plane expressed in terms of hardness increment is constant. © Published under licence by IOP Publishing Ltd.
