ANTIBACTERIAL ACTIVITY OF CARBON-BASED NANOMATERIALS, REVEALED WITH USE OF LUMINESCING BIOTESTS ^{[№ 10 ' 2013]}
Methodical approaches to carrying out biotesting of carbon-based nanomaterials (CBN) with use of luminescing biotests are developed. Use of similar approaches allowed to calculate probable biologically safe concentration of CBN in natural and production environments, and also to identify the CBN main properties conducting to development of toxic effect.

INVESTIGATON OF CARBON-BASED NANOMATERIALS BIOLOGICAL ACTIVITY IN BACTERICIDITY TEST ON ESCHERICHIA COLI AND BACILLUS SUBTILIS ^{[№ 12 ' 2011]}
Influence of 10 carbon-based nanomaterials (CBNs): single- and multi-walled carbon nanotubes, nanofibres, С60-, С70-fullerenes, and amorphous carbon on viability of Escherichia coli K12 TG1 and Bacillus subtilis 168 is investigated. With use of named modeling microorganisms the CBNs bactericidal effect which progressed in time and depended on nanocarbon structural organization is shown. Comparison of test objects reaction shows B.subtilis little big sensitivity in comparison E.coli at high comparability of the biotesting results (r=0,927; P <0,005).

MATHEMATICAL MODELLING OF RADIOACTIVE NUCLIDE MIGRATION IN SOIL – VEGETATIVE COMPLEXES OF ORENBURZHYE ^{[№ 9 ' 2005]}
Research of migration of elements on a soil structure is one of the important approaches to studying of anthropogenous influence on vegetation. Radioactive nuclide migration on a ground structure occurs due to moving of soil particles, which form its structure, due to movement of the soil moisture, containing soluble and colloidal their forms. Sorption of heavy metals is carried out due to two processes fast – exchange and slow not exchange.
