Description
The article presents the architecture of decision support system for the adequacy of the level of lending to small agricultural companies, which implements in its functionality the complex of models: the optimization of selling price of products, the efficiency mark for using of credit funds of single-product and multi-product companies by determined and fuzzy methods, assessment of the system stability of the enterprise. The system has the ability to work remotely using cloud computing, in which computing resources provided by the Internet users in the form of "online service". The article substantiates the need for the development of decision support systems for the adequacy of the level of lending to small agricultural enterprises. We have compiled requirements for the development of an appropriate system and identified a set of models to be implemented in the DSS , described the relationship between them and the technique of working with them. We have also defined names of the input and output data at various stages of working with the DSS as well as the generalized algorithm of the system. Based on the above, the article proposes and describes the architecture of decision support system. It is concluded, that the DSS is an interactive automated system that uses a model of decision-making, providing users with efficient access to data and provides them with a variety of opportunities to display information

Description
In this article, we have presented a number of modeling experiments to investigate the chemical pollution of brown calcareous soil. It assesses the stability of brown calcareous soil of a nature reserve called Utrish to contamination with heavy metals in biological parameters. Pollution of brown calcareous soil with Cr, Cu, Ni, Pb and oil causes a significant reduction in biological parameters. The degree of reduction depends on the nature of the contaminant and its concentration in the soil. The study showed that the indicators used in the biological condition of the soil, could be recommended for use for diagnosis, monitoring, and regulation of chemical pollution of brown soil. According to the degree of resistance to chemical contamination, the brown soils of Russia form the following series: typical brown - brown carbonate - brown leached

IN SEARCH OF SENSES (SOCIAL CONSCIOUSNESS IN WORKS OF G. A. KOTELNIKOV)
DescriptionIn the recent past, class-consciousness was considered one of the expression forms of social consciousness and acted as its main form due to close interaction with interests of people. The class-consciousness and the consciousness of classes were two separate matters of consideration. It was supposed that the essence of class-consciousness and of the class-psychology concomitant with it could only be comprehended in consideration of structure of the social consciousness as a whole. The correlation and interconnection of social psychology and structural units of social consciousness and ideology was a topical issue. However, it should be noted that any consideration of the social consciousness and psychology is just a naked abstraction when it is made in any of their interpretations with no account taken of the material bearer, i.e. the human who is a living organism, and of population, genetic and environmental circumstances. Therefore, talking about the class-consciousness and revolutionary nature of consciousness of the working class, we meet the following expected question: how can we talk about any progress if everything comes to destruction and further formation of an allegedly classless society with bloodshed and death of a significant part of population? At the same time, we can observe reemergence of the thesis of human heterogeneity that the humankind is not a single species but a biological genus. The species this genus consists of have their own genus-consciousness, which is also aggravated by race features and race consciousness. That is why there is actually no sense in talking about peculiarity of the class-consciousness and social consciousness regardless of certain society encased in some geographical shell. Research in this field is worth being developed after moving to the level of biosphere

Description
Large agricultural load on the steppe landscapes leads to the transformation of ecosystems and effect on all their components. Transformation of lands into laylands leads to a gradual restoration of anthropogenically disturbed steppe ecosystems. Studies that focus on the research of comprehensive processes in the territory of laylands are extremely relevant today. Herpetobiont fauna is one of the important characteristics of ecology and biology of soils. Herpetobiont Coleoptera can serve as indicators in the study of processes occurring in postagrogenic soils.The article presents the results of the study of changes in mesofauna, composition and structure of complexes of the gerpetobiont Coleoptera of ordinary black soils in natural succession series of different-age laylands. We also evaluated the degree of faunistic similarity of plots of laylands and allocated dominant species. Carabidae and Tenebrionidae are the basis of complex Coleoptera in the investigated laylands. The article shows that such indicators as the number of individuals, species, families of beetles and their dynamic density are depended on the age of the layland. In addition, the indices of biodiversity (Margalef and Shannon) and dominance (Simpson) are also connected with the age of plots of laylands

Description
We studied the effects of heavy metal pollution on soil phytotoxicity cities of the Rostov region. The research objects were the soils of urbolandscape towns: Taganrog, Novocherkassk, Gukovo, Shakhty, Azov. The study of the soil pollution with heavy metals was recorded in Gukovo, Shakhty, Taganrog. The degree of pollution of the studied cities form the following row: Gukovo > Shakhty > Taganrog > basics > Novocherkassk. The research was carried out in 2011-2015 at the Department of ecology and environmental Sciences of southern Federal University. In most cases, there was a direct correlation between pollutant concentration and the degree of deterioration of the studied soil properties. Used biological indicators are informative for monitoring of urban soils polluted with heavy metal. The degree of informativity of biological indicators form the following row: root length > germination >length of shoots. The results of the study can be used for monitoring and diagnosing the condition of contaminated soils, in the assessment of environmental impact, risk assessment of natural and synthetic disasters, the development of regional standards on the content of heavy metals in soil and in other environmental and industrial activities

Description
We have investigated the influence of nickel oxide in the amount 100, 1000 mg/kg of the soil (1, 10 MPC), combined with the influence of variation magnetic field with induction of 50, 100 and 650 μT power frequency of 50 Hz on the enzyme activity and phytotoxity of the southern chernozem. We have established significant reduction of enzyme activity of catalase and length of roots after the influence of the variation of magnetic fields. Pollution by nickel as an independent factor caused stimulation of enzyme activity of a dehydrogenaze and length of roots of radish. The greatest inhibition of the activity of all indicators was observed at joint influence of magnetic fields and pollution by nickel of concentration of 1 maximum permissible concentration (1 MPC). Enzyme activity of dehydrogenaze was significantly stimulated (p
