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

PROSPECTS OF USING INVASIVE LEGUMES IN HERBAL MEDICINE
DescriptionThe authors propose to consider alien invasive species as new bioresources. These plants form powerful (usually single-species) thickets in the secondary range and their size are larger than at the native cenosis. The territory occupied by invasive species, especially in disturbed habitats, is quite high, so their possible yield is very high. The main problem of using alien species in the pharmacological purposes is the lack of information about the dynamics of the chemicals accumulation. Available data on the biochemistry in its natural habitat is inadaptable for the same taxon in the secondary range because of significant microevolutionary changes. In this work we present the results of phytochemical screening four legume species, formed invasive populations in the Middle Russia - Galega orientalis Lam., Lupinus polyphyllus Lindl., Robinia pseudoacacia L. & Caragana arborescens Lam. Information about these species as traditional medicine plants is given. Original data on the concentration phenolic compounds and biophile silicon in leaves and inflorescences are presented. Information on the fractional composition of the flavonoid complex is done. Taking into consideration the high adaptability of invasive species, the chemical analysis of the samples from different ecotypes was made. It is shown that accumulation of bioactive agents & biophile silicon isn’t depended on the environmental conditions. Concentrations of polyphenolic compounds were at the average level in comparison with medicinal plants. Thus, the combination of flavonoid complex with biophile silicon provides pharmacological significance of studied species, and justifies the needing the further study of invasive plant species in order to create new herbal medicines

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

FORECAST OF THE AGRICULTURAL DEVELOPMENT FOR THE AMUR REGION
DescriptionThis article explains the relevance of evaluation of agricultural growth, which can be achieved through the implementation of agricultural sectors’ innovative potential. The opportunities of agricultural growth are defined by the set of macroeconomic, sectoral and regional factors as well as the type of enterprises that have different levels of innovative susceptibility. The authors give an overview of the main methods of social and economic forecasting and justify the choice of the ARIMA (Autoregressive integrated moving average) as a tool for forecasting regional development of agriculture. The article presents the experts’ estimatesbased values of integrated indicators of agricultural exogenous factors and the ARIMA-parameters based on the use of these indicators for time series prediction of agricultural production in the Amur region. The authors conclude that the time series ARIMA-model of the gross agricultural production, taking into account the influence of innovation potential factors, demonstrate a good approximation to the Amur region data. This article also compares the forecasts of agricultural production on inertial and innovative scenario for the Amur region, and provides an estimation of innovation potential growth of the agricultural branches

FINANCIAL SECURITY OF COMMERCIAL BANKS: CRITERIA AND INDICATORS
DescriptionThe financial security of a commercial bank is a set of stages of financial security for a single commercial bank at a certain period. The financial security is interrelated and therefore establishes a system of indicators of threats to financial security banks. These indicators in the financial security of commercial banks have to meet the requirements of the system, which means they should reflect the main areas of activity of commercial banks and be related to their processes of development. The system of indicators reflects the main areas of occurrence of internal and external threats to the financial security of commercial banks. The system of indicators from external threats contains indicators on federal and regional levels; the system of indicators of internal threats developed for the structural elements of credit and financial security, and reflects all aspects of the activities of commercial banks. The indicator system provides the threshold values of each indicator for the internal and external threats separately; they give marks in the calculation of the financial security of commercial banks. The threshold values reflect the dynamics of the activities and development of commercial banks and therefore change over time. In this regard, the development and improvement of the activities of commercial banks, thresholds of indicators should be reviewed. The system of indicators allows having a comprehensive evaluation of the financial security of commercial banks from external and internal threats
