Description
In the article, we have proposed regional environmental standards for heavy metals, oil and oil products in the main soils of southern Russia

Description
In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear

Description
There are the results of the research of risks to the customer and outsourcing company while execution of a contract of a finance and accounting outsourcing. The risks before and after the transfer of financial and accounting functions for the outsourcing were compared. The methods of developing management solutions to reduce the risks for both parties of financial and accounting outsourcing are presented. The article can be useful for managers of small and medium enterprises, financial officers, directors of companies providing services of the financial and accounting outsourcing

USAGE OF THE BACTERIAL PREPARATION “DESTROIL” FOR DESTRUCTION OIL POLLUTION IN FRESH WATER
DescriptionThe researches of degradation of oil products in fresh-water reservoirs at the expense of the activity of petrooxidizing bacteria of Acinetobacter speivs SN-2 are carried out. The decrease in the content of oil products in 25 days prior to maximum concentration limit (0,05 mg/l) and the increase in concentration of oxygen in the reservoir are defined

Description
The results of theoretical analysis and application development of the marketing concept that underlies the market policy of the university, determining the direction and content of the education services, creating opportunities and conditions for self-learners and graduates are given. Special attention is paid to the marketing of education services and self-employment of graduates, focused on high technology and scientific capacity production, as potential innovators of Russian economy modernization, which is to acquire the features of new economy and knowledge economy. The article can be useful for economists and technical specialists dealing with the problem of increasing the efficiency of educational institutions, employment of graduates and development of self-employment

BIOLOGICAL ACTIVITY OF URBAN SOILS (ON THE EXAMPLE OF ROSTOV-ON-DON)
DescriptionAbout 40 soil cuts were made in various parts of the city of Rostov-on-Don. The determinations of enzyme activity (catalase, invertase, polyphenoloxidase) were carried out in natural and antropogenic soils of a sub-urban park, residential and industrial areas of the city. The enzyme activity of soils in urban condition signif-icantly lowers than in non-urban soils. It is established, that significant impact on the biological activity has duration of sealing, and the longer the period, the higher the negative impact on the enzymes activity. However, a close relationship between humus state of soil and its enzyme activity kept in a condition of ur-ban pedogenesis. The high activity of investigated enzymes is typical to soil horizons which contain the highest amount of soil organic matter

DYNAMICS OF ENZYME’S ACTIVITY OF BLACK SOIL WHEN POLLUTING WITH ANTIBIOTICS
06.00.00 Agricultural sciences
DescriptionIn the article, we have studied the effect of antibiotics on enzyme’s activity of black soil. Introduction of the high doses (600 mg/kg) of antibiotics benzylpenicillin, nystatin) leads to considerable decrease in enzyme’s activity of soils. The class of hydrolyses is most sensi-tive to the action of antibiotics, their activity decreases for 50-70% from control values, the class of oxidore-ductase is least sensitive (10-40%). Antibiotic’s action on enzyme’s pool of soils has the prolonged character

Description
The soil properties out of playing areas of golf courses (so-called roughs) have an influence on the lawn vegetation state. Heavy texture of the soil has the cause of deterioration of the water-air properties of soil which is accompanied by changes in the nature of addition grass lawn from solid to mosaic. Non-aggressive grass of the artificial lawn has one of the reasons for renewal of native flora and the formation of a new type of plant association, closer to the natural vegetation of the Don floodplain
