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.

Keywords: nonisocyanate polyurethanes, cyclic carbonate oligomers, hybrid polymers

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.

Keywords: bioethics, bioethical discourse, sociological approach, social relations, social interactions, institutional mechanism, social control.

In the article the problem of determining the nominal size of real particles of grain materials, which significantly affect the technological parameters of the hoppers and their design parameters. Are specific correction factors for sredenegeometricheskogo razsmera nektoryh ubiquitous forms particles loose body.

The work is devoted to the synthesis of a linear acceleration sensor with two axes of sensitivity behavioral model based on the mathematical model of this device in the differential equations form using MatLab software package Simulink environment. The results of the dynamics simulation of the synthesized behavioral sensor model in the form of transient and spectral analysis of the system reaction are shown. The main idea of analysis is to study the frequency parameters and damping properties of the object. The experiment has identified high quality factor of the oscillatory system, due to small damping, it is reflected by the slow decay of transient and pronounced resonances.

The article emphasizes that every year the number of disasters and accidents is not reduced. Accidents and disasters killed a significant number of people. In order to reduce the deaths of many people and arrival in the emergency zone emergency rescue units as quickly as possible it is necessary to calculate the maximum possible path entrance to the emergency area. This should be done not only just the calculation of distances, but also to be taken into account dynamically changing environment in the emergency area. In accordance with this article proposed a modified method Hakimi, which will allow to solve this problem quickly and at lower cost.

Keywords: Emergency road entrance, the method Hakimi, reallocation of resources, unmanned aerial vehicles, vertex count, edge count, rescue, analysis of accidents, correction of topographic maps, vertex of the graph, many ways

The issues of spatial orientation and navigation in the environment of large university complexes. The various functional and urban planning types of university complexes based on spatial orientation. The problems of spatial orientation in the built environment for the two types: urban "local" systems "integrated" type; Country (or suburban) campuses. Was investigated systematized modern "language" of visual communications for the university environment. Stand "information carriers" and "information structures" among university complexes "functional spatial structure" building "composite structure", "decorative plastic" and "semantic-graphic" structure. The conceptual model of the "frame of orientation" university environment as a complex system of spatial orientation of the inner and outer three-dimensional structure of the building. Marked methodological stages of the project forming a "frame of orientation" for new construction and modernization of university complexes. Stages based on three levels of visual contact "newcomers" and open objects and interior environment of the university complex "occurrence" on Wednesday, "awareness" of the environment, "dissolution" in the medium.

Keywords: university complex, spatial orientation, visual communication

On the example of these regional sociological researches the problem of integration of labor migrants into the accepting communities of the South of Russia, in the conditions of external calls – political crisis in Ukraine and waves of stressful migration is analyzed. As the factors defining the population attitude towards migrants are considered: social and economic well-being, dominating social identity of the population, the general migratory situation in the region
