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

ECOSYSTEM DEGRADATION OF THE LIMESTONE MASSIFS OF WESTERN CAUCASUS AFTER DEFORESTATION
DescriptionSignificant changes in mountain ecosystems occur after deforestation on limestone massifs of the Western Caucasus. Tall-mountain-meadow vegetation with a large variety of species formed at low and medium soil disturbance 3 years after logging. Physical and biological properties of calcareous soils also vary greatly. The values of biological activity decrease at the maximum load is more than 10 times. Biological activity is increased by 20-50% or more cutting stations with low disorders. Biological properties of soils (especially the enzymatic activity) are very sensitive indicators of changes that have occurred as a result of logging. Changes in the activity of soil hydrolases different from changing oxidase activity at different times after logging

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

TOURISM SEGMENTATION AS A CONDITION OF THE CONTEMPORARY MARKET OF TOURISM
DescriptionThe necessity to divide tourism to different parts has been stated in the article; we have also examined lots of tourism classifications and proposed the author’s segmentation of tourism according to nowadays tourism market condition

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

EFFECT OF RECREATIONAL LOAD ON SOIL RESERVE “UTRISH”
04.00.00 Geological-mineralogical sciences
DescriptionThe original soils were investigated at the Black Sea coast of Russia. Severe degradation of the soil in a Utrish nation reserve were identified as a result of high recreational pressure. Soils with high recreational load have low humus content (2-3 times) and a lower en-zymatic activity than the control of the soil. Biological parameters can be successfully used for environmental monitoring of soil of Utrish reserve, in contrast to the chemical and physic-chemical properties

MARKETING OF KNOWLEDGE ECONOMY AND KNOWLEDGE MARKETING. PART 1
DescriptionThe article presents the results of analysis of assumptions, reasons and sources of selection and formation of marketing knowledge as the field of marketing with a specific object and subject of research. It is shown, that the theoretical and methodological basis of marketing requires a complement to the development of innovative marketing methods, models, instruments and mechanisms, allowing to solve the problems and tasks of formation and development of the economy and the knowledge society
