In this article shows the known constructions of gravitational continuous devices for mixing of bulk materials and the conditional classification of these devices. There is the problem of obtaining mixtures in cases when the volume-weighted amount of one component of the mixture is significantly greater than the second (with the ratio of their mass fractions of 1:10, and more). Typically, in the production for mixtures with a ratio 1:10 are used mixers centrifugal type, which operate in a periodic mode. The problem could be successfully solved using gravitational devices that operate in a continuous mode. The classification represented according to the design of mixers. The levels conventional classification for these mixers: (a) used or no additional mixing elements ; (b) the nature of their physical - mechanical properties.

One of the components of the optimization problem is a set of constraints describing the basic requirements for solutions. So as to find a solution that fully satisfies all the wishes of the experts, it is not always possible, the search area extends through analysis of semi-feasible solutions. The adjustment of the system constraints may contribute to changes in the structure and appropriateness of the decisions. The paper shows the ways to form a generalized membership functions of vague constraints of optimization problems based on the logics of Reichenbach and Lukasiewicz. It is known that for the same design procedures in some cases it is necessary to obtain accurate solutions, while others just get approximate solutions. Therefore, we analyzed the features of membership functions obtained using these logics. It is shown that by implication deny rules to allow logic-based Reichenbach membership function takes values equal to one if the value of the function allow rule is one, or if the value of the function deny rule is zero. By implication deny rules in allowing based on Lukasiewicz logic membership function takes values equal to one if the value of the function allow rule is greater than the value of the function deny rules. Therefore, it can be argued that when designing systems with increased reliability (precision) is more expedient to use the function implications for Reichenbach deny rules in a permissive compared with the same implication by Lukasiewicz. The implication deny rules to allow for the Lukasiewicz appropriate to use when designing subsystems that perform secondary functions that are not systemically forming, etc.

The purpose of the research was to develop and implement self-study support materials to facilitate the French for Specific Purposes (FSP) curriculum implementation in mixed-speciality groups of engineering students. The context in which the course emerges and characteristics of mixed-speciality groups of engineering students are given in the paper.The authors hypothesized that such self-study support materials should be developed on the basis of active, student-centered learning and promote 21st century skills. Project-based learning was suggested as the main teaching method. Examples of students’ projects are given and the project stages are described. A blank report form was developed as a mean of project support.

Based on the identification of structural and functional characteristics of the performance and productivity of work, taking into account the balanced development of the region reproduction proportions, constructed cognitive map interaction of regional reproduction proportions with the external environment. In the research was carried out expert assessment of the direction of influence factors in the cognitive model predicting the dynamics of reproduction proportions of the region, on the basis of what has been built cognitive simulation model for predicting the dynamics of reproduction proportions region. This model can be used in determining the degree of influence estimation performance and efficiency of work on the system regional reproduction.

Recent advances in chemistry and technology of nonisocyanate polyurethane (NIPU) materials based on cyclic carbonate oligomers are reviewed in this paper. Reaction of the cyclic carbonate and amino groups results in β-hydroxyurethane fragments with specific properties. Primary attention is given to the hybrid materials that contain epoxy and acrylic compounds, especially materials based on renewable raw materials. Hybrid organic composites comprising of silanes are also considered. An overview of the recent publications in this field is provided with a more detailed description of achievements by the authors and their corporate employees. The use of NIPU materials as coatings, adhesives, and foams is described.

The place and the role of bioethics in the system of social relations and interactions are shown in article. The bioethics as the formed social institute creates social mechanisms of ethical control of rapidly developing biotechnologies. Its syncretic and multilevel character gives the chance of "maneuver" in development of moral positions and adoptions of moral decisions not only in difficult situations of application of biomedical technologies, but also in certain sociocultural, medical contexts. The author comes to the conclusion that from the point of view of the social relations and interactions the bioethics corrects tension in relationship of science and society, axiological mechanisms of regulation of this tension, ethical mechanisms of realization of medical practice, defining the borders of a moral choice and moral responsibility, it acts as social control of modern scientific knowledge.
