Zinc oxide films obtained by sol-gel method from film-forming solutions

Thin ZnO films on silicon and quartz substrates were obtained from a film-enriched ethanolic solution based on Zn(NO3)2⋅6H2O and salicylic acid. The effect of salicylic acid on the processes occurring in the film-forming solution was studied by IR spectroscopy, proton-magnetic resonance, and viscometry methods. The formation of zinc salicylate nitrate in an ethanol solution is established, where salicylic acid exhibits a monodentate property in the carboxyl group. Thermal formation of zinc oxide was determined by thermal analysis and X-ray diffraction. The analysis of optical and electrophysical characteristics of ZnO films was carried out using spectroscopy, ellipsometry and also a block for measuring the electrophysical properties of thin-film materials. It was found that ZnO films were semiconductors of the electronic type, characterized by an optical band gap of 2.91–3.21eV, a surface resistance of 109–106 Q. and transparency coefficients in the visible spectral range of 0.80–0.96. It was shown that as the thickness of the ZnO films increased the resistance decreased

Study of composite coal-water fuel rheological properties

© Published under licence by IOP Publishing Ltd. The rheological characteristics of composite water-coal fuel, as well as the possibility of reducing the viscosity of composite water-coal fuel due to the use of nanomaterials, are studied. Improved rheological properties of composite fuel containing small additions of these substances: carbon nanomaterial at a concentration of 0.005 wt. % or 0.3 wt. % of the dehydrated carbonate slurry. Possible mechanisms for changing the viscosity properties of fuel are considered

Efficiency of Human Plague Vaccination in Tuvinian Natural Plague Focus

Background. Plague is an especially dangerous natural focal infectious disease belonging to a group of quarantine infections. There are eleven natural plague foci in Russian Federation. In Republic Tyva plague endemic territories include Ovyur, Mongun-Taigin and Tes-Hem areas where Y. pestis strains are intermittently isolated from Citellus undulates. Population living at the territory of the natural foci get immunoprophylaxis against plague at complication of epizootic and epidemic conditions.This paper presents the results of monitoring indicators of the immune status of people vaccinated with the plague vaccine living in the territory of the Tuva natural focus.Materials and methods. The study involved 76 volunteers who had not previously been vaccinated. The study included the determination of production IFN-γ, IL-4, TNF-α by blood cells, titers of specific IgG antibodies to the capsule F1 antigen of the Yersinia pestis, and concentrations of immunoglobulins in serum blood, as well as immunophenotyping of blood lymphocytes.Results. In the course of a comprehensive immunological study, features of the development of cellular and humoral reactions in people living in the territory of the Tuva natural plague focus were established in the first months after vaccination. Changes in the concentration dynamics of the main classes of immunoglobulins were accompanied by an increase in the level of specific IgGs to the F1 within 6 months after immunization. In the same period, a significant increase in the production of cytokines, as well as significant changes in terms of the subpopulation composition of the vaccinated blood.Conclusion. It is necessary to note the importance of studying of the human immune status in 1–3 months after plague vaccination as this period coincides with potentially dangerous season from epidemiological point of view. Nevertheless, much important role for improvement of tactics of the specific prevention measures plays the data received after the revaccination

MULTICULTURALISM AND EDUCATIONAL PRACTICE: PROBLEMS OF SOCIO-CULTURAL IDENTITY PRESERVATION

The article touches upon the actual problem of our time, related to the influence of the policy of multiculturalism on educational sphere of specific countries. The authors explore the factors that contributed to the formation of this policy in educational system. The positive and negative effects of multiculturalism, which are manifested in educational institutions, are analyzed. The signs of transformation of traditional value system under the influence of multiculturalism are revealed. The authors outline new trends, which bears in itself multiculturalism, being introduced into the educational space of Russia. Particular attention is paid to the subject-object relations in educational process. The authors draw attention to the role of information technology in the spread of multiculturalism in the educational sphere of any society. The article proves that the newest information technologies guarantee the subjects of globalization a priority not only in economy, but also in culture. Global education involves the distribution of the world according to the subject-object attribute. The nations that nowadays play the role of the object of globalization rely on the appropriate educational level. Particular attention is paid to the analysis of the prospects for the implementation of the policy of multiculturalism in education as a social institution. The authors conclude that under modern conditions of development of society, an education development strategy should help solve problems of the regional level, optimally fitting into the global context
