This paper’s material is destined for high educational institutions’ graduate students and teachers whose professional activity is connected with problems of descriptive geometry and engineering graphics teaching improving on the basis of modern computer technology. The paper will be useful to students of technical universities in their further understanding the course of descriptive geometry and inoculation them an interest in their personal geometric and graphic training, without which a quality engineering creativity is impossible. The paper focuses on use of KOMPAS-3D software possibilities which enables solution of nearly all educational, as well as professional engineering and graphics problems. At the same time, the promotion of domestic IT-product in educational area is an urgent task, arising from the problem of technical education at the present stage of public education’s system development. A number of examples related to solution of spatial problems connected with second-order surfaces simulation have been considered. On the basis of descriptive geometry’s laws applicable to surface problems, a feature of their solution and display on computer screen has been illustrated. For example, in the graphic editor KOMPAS-3D there is the Ellipse command, but there are no Hyperbola or Parabola commands. But without these curves it is impossible to create a 3D model of hyperboloid (one- or two-sheet), paraboloid, or hyperbolic paraboloid. To create these curves it has been proposed to use conics of circular cone, canonical or parametric equations of hyperbolas and parabolas. For each of these options the examples of second-order surfaces 3D models creation have been considered.

The article describes the main components of the selection evaluation of organizational and economic instruments for sustainable development of fuel and energy complex. The most universal system of indicators of sustainable development is revealed, the aim of which is the substantiation of decisions, awareness of various problems, evaluation of the effectiveness of efforts being made on the basis of analysis of socio—economic, legal and environmental indicators. The main problems and threats that affect the state of the investment field of fuel and energy complex are determined. The need to rationalize the investment flows and ensuring close links between investment and research activities aimed at protecting the environment is concretized.

This paper presents the results of studies of biological value and safety of summer sausage, using electromagnetic treatment with low frequencies of raw meat and starter cultures.

In modern conditions of young professionals’ preparation the transition to traditional disciplines teaching by the way of assimilation of information technologies and computer aided design systems is on the table. The concrete steps stated in this paper can serve as a basic point to creation of original technique related to descriptive geometry teaching and will be interesting for majority of experts in the area of geometrical and graphic disciplines and computer-aided design systems.

Nowadays, the creation of technologies, allowing to reduce the cost production of meat products, while ensuring the preservation of the consumer defined quality standards, are urgent issue. As the biotechnology development, so it is possible to develop and introduction of new technologies, aimed at intensifying the complex of complicated biochemical processes, that occur in the meat raw materials in the sausages production.
