Description
Improvement is offered for working bodies’ forms in devices for preparation of forages by methods of engineering geometry and computer graphics. That opens not only great opportunities for intensification, increase in productivity and efficiency of the technological processes, but also opens ways for creation of small-sized devices for their realization. Constructive study of geometry of working bodies surface, allows us to give wavy movement to particles of forage and impart them the movement with bigger power consumption. In such installations forage particles components, meeting walls of working body, change their direction and, meeting other portions of particles of forage components, mix up. From loading to unloading, throughout the installations working body length, flexible and strong waves of forage particles components movement inside the working body are born. The conducted pilot studies have shown that as a result of working bodies’ forms improvement of devices for preparation of forages by methods of descriptive geometry such devices can be implemented in a variety of industries

Description
The rapidly developing processes in global information development of our society have had a significant impact on education. Recently, in agricultural and other universities the amount of generated and processed pedagogical information has dramatically increased. Spontaneously and purposefully, electronic databases of educational information and educational portals have been created. All these works require a significant investment of time and effort of the teaching staff (PPP) of higher education institutions and a large number of technical experts in the field of information technology; they also require appropriate computer and communications equipment. All this is already an accomplished fact. On the other hand, the question arises about the degree of meaningfulness and expediency of certain aspects of this process in the form in which it is actually carried out, and evaluation of its impact on the mission of the University in General: "Training high-quality professionals", in particular for the regional agro-industrial complex (AIC). Apparently, now this process develops spontaneously, and no one has planned it, considering on the one hand, the costs of various kinds on its implementation and on the other hand - ensuring its effectiveness in achieving the objectives and getting the intended desired results both in physical and valuable forms. The meaning and justification of this process can give only a substantial positive impact on improving the quality of education, and only when it has adequate and reasonable cost. For a reasoned response to these questions, the authors propose to apply the theory of reflexive management active objects, automated system-cognitive analysis (ASC-analysis), functional cost analysis (FCA) and the method of "Direct costing". A foundation for solving the problem: this is a great experience in teaching and research activities, a successful experience of the application of ASC-analysis and the FSA for personnel management; a software tool of ASC-analysis which is an intellectual system called "Eidos" (full open free access)

RISKS AND PRIORITIES OF THE STRATEGY OF DEVELOPMENT OF THE NATIONAL SPACE-ROCKET INDUSTRY
DescriptionBased on risk analysis and consequences of the accidents which have happened to the space equipment from the moment of the beginning of an active phase of space activity, the authors have come to a conclusion that initial stages of life cycle of the project, namely start and a conclusion to an orbit of artificial Earth satellites are subject to the greatest risks. Further functioning of the spacecraft in an orbit is accompanied by much smaller risks, and the least risky are works on service of land infrastructure, processing and information transfer to consumers. Methods of economic protection, which provide acceptance or transfer for a certain payment of risks are not always acceptable for an initial stage of the space project – start and removal into a satellite orbit. Authors suggest evading whenever possible from similar risks for what it is necessary to reduce starts for the benefit of foreign customers. The research of structure of the world space market has shown that such kinds of activity as production of land space infrastructure and rendering services of satellite communication and broadcasting are the most demanded. The market of starting services is gradually reduced in connection with miniaturization of the equipment of satellites and high specific risks of start. The policy of Roskosmos is focused generally on preservation of leadership in starting services which differ in high risks, to the detriment of creation of own satellite group capable to render a wide range of space services to foreign partners. Change of reference points of the strategy of development of the domestic spacerocket industry towards highly profitable and least risky types of space activity is offered

Description
In the context of implementing programs on reducing budget expenditures for the social sphere utilities, it is urgent to intrude renewable energy sources into the practice of their energy supply. However, despite all their diversity, not all constructions based on renewable energy sources can be used under conditions of urban development. Besides, the mutable nature of the solar radiation coming on the Earth's surface requires specific forecasts and calculations of its intensity. Accurate estimation of the area solar energy potential of the generating plant proposed location allows not only to justify its parameters at the design stage, but also to predict its operating mode and to evaluate its technical and economic efficiency. The purpose of the article is to estimate the level of solar radiation for Volzhsky, Volgograd Region, at the initial stage of designing and justifying the implementation of power plants transforming renewable solar energy in urban areas. In the article, it is proposed to apply method for estimating the solar energy potential of at a specific geographic point, based on a combination of the calculation method for determining the solar radiation characteristics and actinometric measurements. Volzhsky of the Volgograd Region, like most settlements in the Lower Volga region, has a high solar energy potential: 1228.8 kWh / m² for the horizontal surface of the southern orientation of the receiving surface of power plants, which can be increased by 16.2% at its optimal orientation relative to the horizon and the sides of the world. However, the expansion of the utilization of the solar energy potential of the district may be limited to the location of the existing buildings and structures at which power plants may be located in urban development conditions

DEVELOPMENT OF A DECISION SUPPORT SYSTEM FOR SUSTAINABILITY ASSESSING OF A COMPANY
DescriptionSustainability of enterprises plays an important role in the economic and social life of all industrially developed countries. Despite numerous publications devoted to the analysis of the sustainability of organizations, there are still ambiguous approaches to the methods of analysis for different authors. In addition, for companies of different industries, forms of ownership, geographically located in different regions of the border, the methods and indicators for assessing sustainability can vary considerably. In this connection, there is a need to develop a decision support system that would allow the most efficient assessment of the sustainability of the largest possible range of enterprises, with the possibility of adjusting and flexibly tuning as many parameters as possible. The article describes the architecture and algorithm of the DSS, which implements the following model of initial data generation in its functional; Model of formation of a tree-like structure of groups of indicators on the basis of which the stability is assessed; Model for specifying the fuzzy sets belonging to the recommended values of the indicators; Model for calculating the values of groups of indicators and their fuzzy estimates; The model of graphical interpretation of the organization's sustainability assessment. The developed system was tested on the basis of the company called Antey LLC

Description
At present, electrochemical analysis methods are increasingly used to solve the problem of research on quantitative and qualitative indicators of organic substances. One of the most common electrochemical methods of analysis is conductometry. Along with the straight line, indirect conductometry is often used, in which the substances under analysis react with the corresponding components before the measurement, and the fixed change in electrical conductivity is determined exclusively by the presence of the products of the reaction that occurred. A necessary condition for the application of this method is the presence of ions in the reaction medium, and since the pectic substances are polyelectrolytes, this condition is met, which allows us to use the conductometric titration method to determine the quantitative and qualitative characteristics of pectic substances. The technique we propose relates to technical biochemistry, namely, to the determination of the amount of pectin substances in plant raw materials. We have prepared "standardized" solutions of fractions of pectin substances. Samples of solutions of fractions are taken. Saponification of fractions of pectin substances in the samples of the solutions under analysis is carried out with 2.5 ml of 40% NaOH solution. Fractions of the pectin substances are precipitated with 2.5 ml of concentrated HCl. The solutions to be analyzed are centrifuged in 50 ml test strips at a rotor speed of at least 5000 rpm for 5-7 min. Suspensions of pectin fractions with distilled water are suspended in a beaker for titration with a magnetic stirrer for at least 30 minutes. Conductometric titration of suspensions of precipitates of fractions of pectic substances is carried out with stirring. Based on the results of conductometric titration, graphs are plotted, according to which the volume of titrant consumed for titration of pectic acid is established. Calculation of the mass fraction of fractions of pectic substances is carried out according to the formula. The methodology is distinguished by the simplicity of implementation, which makes it possible to obtain accurate data at high convergence of parallel analyzes, and it saves labor and time costs at all stages of the process
