The composition, basic properties and application scope of the two main types of expanding binders historically most widespread in Russia such as gypsum-alumina expansive cement and expansive cement Type M are given. The expansion kinetics of the binders ranging from gypsum-alumina expansive cement to expansive cement Type M is observed. The role of lime as a supplement and as a hydration product of the Portland cement in the expansion process is shown: as a supplement in small values (2-4%) to gypsum-alumina expansive cement with higher gypsum concentration stabilizes the hardening and expansion process, in higher values boosts the expansion process to self-destruction. Optimization criteria of the expansion kinetics aimed at obtaining project expansion in 10 days of hardening without any additional chemical additives are proposed.

One of the main and most relevant and profitable areas of agricultural production - produce quality seeds in the farms, in the process of post-harvest grain processing. Was evaluated basic parameters of the separation process on the existing scheme sieve winnowing machine with certain technological characterization of the purified grain material according to the different conditions of separation, the possibility of defining a predetermined fraction of a feed and seed quality of purified material. Synthesis was performed variational various separation schemes and functioning to identify optimum operating parameters. According to the results of the experiment set technological possibility and the main characteristics of the process producing high-quality purified fraction of the material given by the scheme, which provides the best performance.

The nano-catalyst ceria (CeO2), activated by Pt nanoparticles, is known for being prospective and efficient material widely used in catalysis, fuel elements, and sensors. One of the most up-to-date methods of catalysts' reasearch is X-ray absorption spectroscopy (XAS) that is sensitive to the chemical state of catalyst's active centers [1,2]. Using XAS in the fluorescense detection mode at CeL1 line with high precision we studied electronic structure of Pt-activated nanoparticles of ceria at various redox conditions. In order to detect partial X-ray fluorescence yield the emission line CeLγ3 was used, which allowed us to increase spectral resolution. We researched local atomic and electronic structure of the materials under study. Oxygen vacansies were found to appear on the nanoparticles surface of ceria at 5% CO He atmosphere. Theoretical modeling of the obtained spectra at CeL1-edge demonstrated good agreement with experiment.

Only innovative activity is able to unite all aspects of science, equipment, economy, business and management. The current state of the innovative sphere of Russia speaks about serious contradictions in its functioning. Considerable scientific and technical capacity of the country was lost in the period of economic reforms. Now often it is impossible to predict precisely succession of events in economic life of the country generally and each organization separately. In modern conditions scientific and technical progress represents innovative development which is defined by the state as the most important priority of economic policy. Innovative potential of any managing subject needs to be estimated as difficult social and institutional system. To encourage managers and the production personnel competently developed motivational strategy is necessary to conduct work on search of innovations. Achievement of the put indicators of innovative development of the Rostov region and the country as a whole has to become result of an offered method of interaction of science, business and authorities.

"This article is devoted to the development of the method for modeling elements of microsystems technology(MST) of membrane type. In this paper perforated membranes are considered and the impact of perforation on the mechanical properties of the membranes is examined. In numerical simulations of the elements it is proposed to use the equivalent mechanical parameters of perforated membranes obtained at the initial stage of the simulation. This will allow to obtain find the optimal parameters of perforation, reduce the time and resource modeling of MST elements. To test the technique numerical experiments were conducted for the two square membranes with sides 1.5 and 3 mm fixed on the contour of the same thickness. We studied the influence of the size of the perforation on the equivalent Young's modulus of the perforated membrane. "
