INFLUENCE OF ORGANIC SOLVENTS ON WATER DISSOCIATION IN BIPOLAR MEMBRANE
DescriptionThe article discusses results of experimental research of the influence of aprotic and proton solvents on reaction rate of water molecules dissociation in the bipolar membrane MB-1 by the method of electrochemical impedance frequency spectrum. It was discovered, that addition of organic component in aqueous solutions results in significant influence on the parameters of water dissociation in a bipolar region of the membrane. The reason for this influence is the reduction of the mass fraction of water in solution and, consequently, in a bipolar region of the membrane, which itself reduces the rate of the dissociation reaction. Another reason for the influence of the organic solvent is its effect on the network of hydrogen bonds existing in water and aqueous solutions. Depending on the nature of organic solvent and its concentration, the network of hydrogen bonds may be strengthened, or destroyed, thus facilitating removal of the proton involved in the reactions between water molecules and catalytic centers in cation-exchange and anion-exchange layer of bipolar membrane, or retarding removal of proton. This leads respectively to speed up or slow down the rate of dissociation in the bipolar region of the membrane, as well as changing the constants of the dissociation reaction of water. Introduction of organic solvent in solutions, which are in the contact with bipolar membrane, is a convenient method of investigating the role of solution composition on the rate of proton transfer between water molecules and catalytic centers in the membranes

INFLUENCE OF HEAVY METALS HYDROXIDES ON WATER DISSOCIATION IN BIPOLAR MEMBRANE
DescriptionThe results of study of bipolar membrane – analogue of MB-2, modified with chemically introduced chromium (III), iron (III) and nickel (II) hydroxides by the method of frequency spectrum of electrochemical impedance, by infrared spectroscopy and scanning electron microscopy in combination with X-ray spectrum analysis are presented. It is shown, that sequential treatment of cation-exchanger, contained in cationexchange membrane, with metal salt solution and alkali solution does not result in formation of complex compounds of these metals with ionic groups of ion exchanger. It was found that in these conditions the presence of heavy metals in the phase of cationexchanger confirmed by X-ray analysis, however, crystals of hydroxides of heavy metals are not detected in the size range of 1000 nm to 20 nm. These heavy metal compounds are thermally unstable and their catalytic activity in the reaction of dissociation of water molecules decreases with increasing temperature during heat treatment. The introduction of low-soluble hydroxides of d-metals (chromium (III), iron (III), nickel(II)) by chemical method can significantly improve the electrochemical characteristics of a bipolar membrane. The most effective catalysts in water dissociation reaction are the hydroxides of chromium (III) and iron (III) and, as a consequence, membranes with these hydroxides have a lower value of overpotential compared with original membrane at the same current density

PAINTINGS BY S. A. GAVRILYACHENKO, AS ILLUSTRATIVE OF THE SOURCE ON THE DAILY LIFE OF THE COSSACKS
DescriptionIn today's world, one of the most urgent problems is applying to study history of everyday life. In this paper first analyzes the reflection of the everyday life of the Cossacks on the paintings for S. A. Gavrilyachenko. The author examines in detail the work of the artist associated with this theme indicates strengths and weaknesses. Particular attention is paid to the precision display of the Cossack everyday life in the artist's canvases. Based on the study, the author comes to the conclusion about the possibility of using S. A. Gavrilyachenko as one of the sources in the study of Cossack life. The work particularly focuses on the specifics of their use is indicated method of analysis of illustrative sources. The article also highlights the daily life of the Cossacks. The paper identifies features of life and development of the Cossacks, is indicated by its role in the history of Russia. Important place in the life of the Cossacks took the Orthodox faith; they very strictly observe the customs, traditions and beliefs. Particularly tragic was the Cossack period of the February revolution of 1917, at this time the destruction of the centralized management of the Cossack troops occurred. A decisive blow to the bar caused the Civil war of 1917-1923 and what happened during the famine of 1921 — 1922, this theme is most fully represented in the works of S. A. Gavrilyachenko

Description
In the article, we consider the problem of ensuring viability of a company in the conditions of innovative development of society. It is shown, that viability of the innovative enterprise can be provided only socially and by ecologically responsible management. On the basis of the analysis of the theory and practice of social and ecological management, the conclusion that controlling as practical implementation of the concept of system business management will allow to provide viability of the enterprise in the conditions of innovative development is drawn. It allowed reducing the considered problem to the solution of three interconnected tasks. First, it is a problem of creation of model of innovative development within the modern theory of economic development. Secondly, this problem of definition and classification of a social organizational unit of independent economic activity, viable in the conditions of innovative development. At last, thirdly, it is a problem of construction within model of innovative development of model of viability of this social organizational unit of independent economic activity necessary here how exactly models of social-andecological controlling. Social-and-ecological controlling acts here as system structural communication which provides possibility of complete overcoming of an initial problem at the complex solution of the specified tasks. Then the problem of definition of a place and the role of the controller and the manager and their system functions necessary for implementation of potential of viability of the enterprise in the conditions of the innovative development put in model of social-andecological controlling is solved

Description
The current problem of environmental pathology has emerged because of physical, chemical and biological factors, most of which are of anthropogenic origin. The environmental pathology is determined by appearance of new and unusual diseases, atypical course of known diseases, and "rejuvenation" of some diseases (diabetes mellitus, hypertension, myocardial infarction and even cerebral stroke among children). Examples of "new" diseases are environmental dioxin syndrome; "strange" disease Minamata (paralysis, mental retardation due to the damage to the Central nervous system of methyl mercury accumulated in marine food products); general immune depression – "chemical AIDS", caused by dioxins, heavy metals, toxic radicals, and others. Environmental issues gradually aroused the need to allocate separate spheres of legal regulation of public relations in the field of natural resources and environment from negative impacts in the course of economic activity. The task of the law in the field of regulation of public relations concerning the surrounding natural world – to define rules of behavior, which will be based on the knowledge of the natural laws. Global environmental problems associated with degradation of natural objects, separate ecosystems and the environment in General, contributed to the formation within the Russian legal system of environmental law as an independent branch of law. The article investigates methodological aspects of improvement of ecologicaleconomic mechanism of management in the sphere of nature management and environmental protection. The legal framework of the state policy in the field of environment protection is to ensure balanced solution of socio-economic tasks, preservation of favorable environment, biological diversity and natural resources in order to meet the needs of present and future generations, strengthening the rule of law in the field of environmental protection and ensuring environmental security. The article defines the interrelation between the level of pollution and the amount of population, analyzes official data for the Krasnodar region
