Samkova E.B., Karimov I.F. ASSESMENT OF LIGHTING SOURCES BIOSAFETY BY REPORTER LUMINESCENT BACTERIA [№ 6 ' 2015] Abstract. In recent years a number of studies purpose was to develop a biosensor methods for the evaluation of mutagenic and carcinogenic effects of environmental factors on the cell, in particular biosensor test systems whole cells that have in their composition two main genetic elements: a promoter that responds to exposure to a toxicant, and gene-reporter transcribed from the promoter. It may be noted that reporter microorganisms very suitable object for the study of DNA-damaging effects, due to ease of cultivation, inexhaustible resources, to ease of changing the irradiation conditions, and finally the ability to transcriptional response that is easy to visualize the level of luminescence of the bacterial strain. In this work reporter luminescent strains that are based on E. coli K12 MG1655: E. coli K12 MG1655 recA::lux, E. coli K12 MG1655 colD::lux and E. coli K12 MG1655 ibpA::lux were used to assess the biosafety sources artificial light, with the first two luminescence respond to DNA damage, and the latter — on the damage of heat shock proteins. For creating optimal conditions for the work of strains was established method of estimating the light, and a comparison of the physical characteristics of light sources, including incandescent lamps, compact fluorescent lamps and LED lamps. The results allowed to state that all types of lamps are able to provide the DNA damaging effects in different degrees, but more important is the brand, rather than the type of lamp; wherein a correlation damage from ultraviolet radiation intensity emitted by all types of light sources. There was also a difference in the response of the features of the strains E. coli recA::lux and E. coli colD::lux.
Samkova V.A. GLOBALIZATION: THERETICAL AND SOCIAL AND CULTURAL ASPECTS [№ 7 ' 2010] Today globalization is an object of interdisciplinary research. Each disciplinary of scientific knowledge discovers specific characteristics, qualitative and quantitative survey of globalization. Globalization and globality are becoming a subject of philosophic, sociologic and culturological reflection. In the course of globalization, interpenetration of different world cultures and identities takes place. World society, according to the Thomas theorem, becomes world-wide horizon which is revealed only if displayed as real in the course of communication. The aim of the present work is to discover different aspects of globalization.
