Convective drying is the most common method of dryingthat may be intensified by the treatment of root crops and vegetables in an electrostatic field. According to the results of the experiments was to determine the optimum treatment time 3-3.5 hours at 55 C, with tension in the range of 20-40 kW / m. Under the influence of the electrostatic processing of hygroscopic moisture removal rate is accelerated. Organoleptic performance compared with conventional convection drying are not changed.

The results of processing of experimental data obtained during the pilot survey, completed in June 2015 among the 3rd year students of DSTU. As a measure of impending conflict was used the level of emotional perception r local and Central political orders. It was normalized from -1 (negative order) to +1 (acceptance of order). The basis of measurements on the method of semantic differential Charles Osgood. Using the theory of ideal points Coombs, levels of perception calculated in the linear approximation and on the previously developed model in the framework of catastrophe theory. Shows the distribution of respondents by levels of emotional perception, calculated by the multi-agent modeling program Any Logic. Obtained that on average the studied audience perceives the local government is neutral (r=0,04). However, 39% of respondents perceive the local order is negative, 53% were positive. To the Central government, on average, the ratio is slightly positive (r=0,13). Negative emotional perception is characterized by 23%, positive – 60%.

The article presents the analysis results for aerated concrete production in the Tyumen region, are considered the distinctive advantages of aerated concrete, as well as significant drawbacks. The basic effects of water absorption of aerated concrete. Describes the process of saturation with moisture of aerated concrete in the construction of buildings, as well as the formation of cracks in the walls in the operation of buildings and constructions, which used the aerated concrete as wall cladding designs. As a result it is concluded that to avoid the effects of moisture (hygroscopicity) on the aerated concrete is possible, by performing additional activities, reducing the time of construction, the proper organization of works at the construction site and compliance with sequence of works.

Due to the fact that currently seepage losses are significant, even with use of such geosynthetic materials like polymer geomembrane, evaluation of water permeability polymeric screens the presence of small lesions remains a major challenge. To simulate the filtration damage geosynthetic polymer screens use software package "Somsol multiphysics», allowing to solve both two-dimensional (plan) and three-dimensional (spatial) problem stationary and non-stationary filtration.

Educational institutions of Russia, including the universities, the task of improving the efficiency of educational work. In this regard, an interesting experience, Rostov state construction University (RSSU) as the University in General and the Department of construction management (OS), in particular. RSSU from 2014 introduced the obligation of all teachers to report specific educational work along with the statement of methodical and scientific works. Depending on the type of educational event is assigned a certain number of hours. The Department OS is a comprehensive educational work, which includes not only leisure activities, but also to involve students in scientific and methodical work. A systematic approach to the education of students involves performing teachers lectures on the history of the country in General, the history of construction and architecture; the participation of students in the preparation of guidelines, research, culminating in the writing of scientific articles and / or registration of a patent for an invention (utility model) or computer programs. Analysis of the annual experience of educational work under the new scheme, led to the conclusion that the best curators, as a rule, are teachers whose scope of training load significantly above average – 1,3-1,5 bets, or pensioners. The analysis of the educational work of the Department OS also launched another criterion for evaluating the work of the curator, if he works at the Department. This is the number of students who are registered to perform the final work to the Department, a representative of which is the curator. A systematic approach to educational work allows even at the beginning of training to select students wishing to do research, to identify young talents and to improve academic achievement in the educational process.

he article analyzes the different forms of integration and cooperation of industrial enterprises from the standpoint of the possibility of capitalization of their resource potential. Under-cap resource potential refers to the process of institutional modernization resource binding interactions of subjects for the growth of economic potential, both the subjects and formed or integration structure. Sources allocated resources capitalization growth industry. The main directions of the capitalization of resources for industrial enterprises operating in the composition of the integrated structure. It is shown how to attract more participants interaction (financial institutions, research organizations, government agencies) promotes the growth of capitalization. Proposed indicators to measure the level of capitalization of the resource potential of integration structures. It is concluded that the choice of form of integration cooperation should be defined as the interaction of the participants goals and objectives of regional development.

We examine how stem taper and the nonuniformity of bark along the trunk affect the efficiency of bundle mechanical decortication in drums.Such decortication enhances the performance of timber-preparation facilities.We demonstrate that the decortication of fast-taper longwood assortments may result in uneven barking along the trunks.Therefore, improvement of the technological process of longwood drum barking will diminish the offgrade portion of the chip and thus will result in better rates of competitiveness.Long size logs are often bent in barking drums. Further studies should take into account the resultant alternating strain in the bark, including stretching and compression. It also appears important to examine the effect of negative temperatures and bark moisture content on the resistance of the bark to the combined effect of stretching, compression, and impact shock.

Presented article provides the results of experimental studies related on the centrifugal impregnation of pine wood process. The studies were carried out respecting influence of the percentage of summerwood and latewood in the impregnated samples on the speed of centrifugal impregnation (impregnant consumption per processing time), and the impregnation depth (the ratio of the volume of absorbed liquid to the total volume of the pore space of a wood sample). On the basis of these results it is shown that the percentage of latewood in a sample does not significantly affect the speed of centrifugal impregnation, while the percentage of latewood affects the impregnation depth (regression model obtained). Furthermore, it is shown that the inner space filled with the impregnant after centrifugal impregnation occurs uniformly along impregnation front trace. The conclusion follows with a list of promising directions for further research on the subject of wood impregnation process using centrifuges.
