WATER STRUCTURE AND DILUTE WATER SYSTEM PROPERTIES ANALYSIS
01.00.00 Physical-mathematical sciences
Description
The cluster structure in pure water (distilled) and water salt solution was considered. The experimental methods of the structural units’ registration in water were analyzed. It is shown that the clusters influence on water properties is insignificant by salt concentration more than 10-5 mole

STRUCTURE AND PROPERTIES OF WATER ACTIVATED BY A MICROWAVE RADIATION
01.00.00 Physical-mathematical sciences
Description
The scientific publications review about the physicochemical properties of pure water and water solutions activated by a microwave radiation was made. The convincing evidences of the water structure changes in the microwave were submitted
-
Description
In the model experiments we studied the effect of combined action of chemical pollutants (PbO 1,000 mg / kg oil 5% by weight of soil) and microwave radiation (SHF radiation) with a capacity of 450 and 800 W (duration 1 minute) on the enzymatic activity, the number of microorganisms and indicators of phytotoxicity of an ordinary black soil. We found that the combined effect is systemic, rather than a simple summation of the effects of individual pollutants, shown no direct proportion between the power of the microwave radiation and its biological effect in the combined pollution

EFFECT OF NON-TRADITIONAL MELIORANTS ON THE MICROBIOLOGICAL ACTIVITY OF SOIL AND GROWTH OF PLANTS
Description
The effect of the new meliorants on the qualitative and quantitative composition of the microflora of loamy sand soil and the growth of pine seedlings is presented. The activization of microbiological processes and growth of plants on the meliorated plots is revealed
-
Description
The assessment results of urban environmental conditions on the basis of accumulation of heavy metals in the soil and vegetation are presented. The questions about the ability of different plants to accumulate heavy metals in the lives are discussed as well

АPIINDICATION AS A PART OF RADIOECOLOGICAL MONITORING
Description
The opportunity to apply products of beekeeping to the environmental control of territories polluted with radionuclides is examined

EFFECT OF SOIL AND ECOLOGICAL CONDITIONS ON THE GROWTH OF SEEDLINGS OF PINUS SYLVESTRIS
Description
The influence of agrochemical and physical properties of a soil on the growth of the seedlings of Pinus sylvestris in the forest nurseries in Chuvash Republic is studied. The correlations of the growth of the seedlings and agrochemical and physical properties of the soil are simulated

Description
The residual amounts of the pesticides in the coastal water of the Azov Sea were studied in spring seasons of 2009-2011. The concentrations of the pollutants were determined and the degree of their danger for hydrobionts was assessed. The concentrations of the pesticides diluted in the water of the Taganrog Bay and the eastern Azov Sea are shown to be lower than the maximum admissible concentrations set for fish-ery reservoirs

Description
In various branches of the metalworking industry, the automation of technological processes is based on the use of inertial convertor-equipped positional electrical drives. The author has analyzed an optimum performance diagram for medium movement of executive unit of the inertial convertor-equipped electrical drive with ideal shafting that had been developed before, and has developed an optimum performance diagram for medium movement of executive unit of the inertial convertor-equipped electrical drive with elastic shafting
