This work provides the results of a study involving activities on reducing noise through the use of multichamber combined aerodynamic silencers in industrial vacuum cleaners. The topicality of this work is associated with the fact that in using industrial vacuum cleaners noise levels prescribed by GOST 12.1.003-83 [1] are exceeded. For instance, the acoustic characteristics of T-1 and NPP-2 [7, 8] vacuum cleaners do not correspond to normative requirements at a rotational speed of n=3000 rpm and a component density of q = 0,01 pcs/m2 [1]. Note that exceeded sound pressure levels are observed mainly in high-frequency areas (1000...8000 Hz) and is about 7...10 dB. As the first version, the study tested a multichamber reactive silencer serially installed on an NPP-2 vacuum cleaner [8], and as the second version, the study tried a new multichamber silencer [13], wherein the interior is worked by a noise absorber with a thickness of 10 mm. In addition, the article presents new solutions in the way of aerodynamic silencers for extract air systems [16, 17] with augmented noise absorption by the walls of the silencer’s body.

This article provides the results of a study into the impact of environmental factors on the state of hemopoiesis in ducks under different housing methods in radioactively polluted territories. The author establishes that with age, the erythrocyte and leukocyte count, hemoglobin levels, and the monocyte percentage increase in birds. The study reveals that raising ducks without using water-bodies (the confinement housing method) can cause relative polycythemia and reduce the body’s natural resistance in the birds.

This article is dedicated to the analysis of Soviet nation-building practices in the North Caucasus. The author examines specific circumstances and institutional mechanisms behind the formation of North-Caucasian nations. The article accentuates the primary role played by the Soviet state in this process, its active part in resolving current social-economic and political objectives. The author stresses the regional nature of nation-building, which was manifested in the North Caucasus in the administrative-territorial instability of autonomies being created. The author makes a conclusion about the sponsored nature of the nation-building process in the region.

Modern trends towards enlarging production and integration processes taking place not only in the national but in the global economy as well lead to the formation of entrepreneurial associations whose most common form in Russia and in the world is holdings. In the context of the development of the management theory, the problematics of managing integrated corporate structures have been examined by R. Koch, A. Thompson, and A.J. Strickland, and a number of other foreign theorists and practicians. In Russian economics literature, this area has been explored by A.R. Gorbunov, A.M. Petrov, S.M. Ishchenko, and others. The fact that there are numerous modern studies in this area indicates the topicality and significance of the subject of this study. The article examines the theoretical aspects of managing an innovation holding company in terms of vertically integrated management structures. The author conducts a comparative analysis of different types of integration structures. In addition, the article explores the characteristics of assessing the current synergy effect in consequence of the integration of companies. The study reveals that the strategic management of the corporate portfolio of a holding company based on synergism helps ensure higher returns on investment when there is a combination of companies as opposed to when they are managed separately.

This article examines a model for prognostic-analytical accompaniment of the innovation development of a regional university based on the creation of a forecast center of its own in its structure. The authors assess the strands and results of prognostic-analytical activity as part of a program for forming the university’s innovation infrastructure as well as working out and implementing a program for strategic development, which warrants a shift to integrated prognostic-analytical support for the university’s activity, which will facilitate the creation of a state-of-the-art model for managing the college. As of now, the ability to engage in systematic prognostic-analytical activity is becoming one of the university’s major competitive advantages. Original methodologies, technology, and analysis findings are a unique intellectual product sought after by the subjects of the regional economy and state and municipal authorities.

This article examines the issue of implementing health promotion technology in the education environment. The major objectives of modern schools: fostering a healthy personality oriented towards a healthy lifestyle; putting together an education and bringing-up process that will not harm the child’s health; using all available means of children’s health protection and development at school. The quality of education can be achieved only through creating certain conditions directed towards preserving and strengthening students’ health. All this requires that instructors employ special approaches in the education/bringing-up process, which are predicated on health promotion principles. Having conducted our analysis, we came to the conclusion that knowledge on preserving and developing health is an important component of the professional competence of a modern teacher, who ought to command a broad spectrum of health promotion educational technology to be able to pick from them those that will ensure the success of a particular student in particular conditions.

Based on the observation materials from 50 weather stations in Georgia for the period of 1936–2011, this article explores climate indices for the moistening regimen – the mean of maximum 24-hour precipitation, rainless and rainy periods. The author constructs geo-information maps for the spatial structure and explores the dynamics of these indices for the period of global warming, assesses the possible risks of the development of adverse climate conditions (high waters, floods, droughts, desertification). The obtained findings can be used in the summation of corresponding indices for the Caucasus region, the Black Sea area, and Western Asia.
