Description
The аrticle is devoted to study of adsorption of enzymes, antioxidants contained in horseradish root on starch to create enterosorbent with anti-oxidant properties. For this goal we have studied adsorption isotherm calculated constants, thermodynamic parameters (change of enthalpy, entropy, and isobaric-isothermal potential); sorption kinetics of enzyme-antioxidants on starch and calculate the main characteristics. The method of producing of enterosorbent - antioxidant on based starches has been developed based on the experimental data. The ready sorbent is a white powder having no taste and smell. In biological fluids and water, it is insoluble. The enterosorbent on starch does not dissolve in water and biological fluids. It is the solid component. This enterosorbent can be used to protect the gastrointestinal tract of humans and animals against a wide variety of oxidants and peroxide. The results of this work will form the basis for the study of the antioxidant properties of the resulting enterosorbent. The results showed that during the tests, the enterosorbent on the starch showed good antioxidant properties. It has high antioxidant activity with respect to hydrogen peroxide

ARCHETYPES IN RELIGION: FUNCTIONS AND METHODS OF RESEARCH
DescriptionThe concept of archetype, introduced by Swiss psychoanalyst Karl G. Jung, eventually went beyond psychoanalytic research area. The concept of archetype was represented in philosophical and cultural context and in each of them, it has acquired a specific connotation. Being the structural elements of the human mentality, archetypes take key position in the culture. Their formative functions contribute to the expression of archetypes on the level of mythology and religion. These eternal symbols, originated from the depths of consciousness, are implemented universally and spontaneously, being manifested largely in religious culture. The article is devoted to the peculiarities of the functioning of the archetypes and identification of their main functions. In addition to that, this article marks the problem of choosing methodology for archetype research. This research allowed to identify the main function of archetypes such as regulative, integrative, protective and communicative

Description
In the article we present the results of comparative researches of herbaceous covering of plant communities in the alpine zone of the Republic of Dagestan on the example of Dido- depression. The plant covering of the investigated region differs in extraordinary variety. The general regularity of plant distribution is vertical zones. There were made 6 ground profiles at different elevations from 1450m to the alpine zone at 2500m above sea level. Variety of phytocenoses is connected as with changes of ground conditions, so with environmental conditions. We have researched and identified the types of grounds with laying of grounds profiles on the vertical zonality. There we studied the specific composition of herbaceous plants on the examined ground and given names to plant communities. The studying phytocenosis are analyzed by productivity of functional groups. We have shown the share of each species and their abundance. Of all plant communities, the mass of herb differ dominates. The composition of plant communities is analyzed, depending on high-altitude grades and degree of anthropogenic load influence

INVESTIGATION OF ASCORBIC ACID ADSORPTION ON KSMG SILICA GEL
DescriptionThe article studies adsorption of ascorbic acid on KSMG silicagel. The experimental results, the basic thermodynamic characteristics of ascorbic acid adsorption on oxide silicon have been used for treatment of adsorption mechanism of ascorbic acid on silica KSMG. Results of the study ascorbic acid adsorption on silica gel KSMG may be used for further identification of it in the various objects

STUDY OF THE INTERACTION OF POLYSTYRENE-AZO-O-PHENOL-AZO-RHODANINE WITH ZINC IONS AND CADMIUM
DescriptionSince the industrial revolution a huge amount of pollutants emitted annually into the water most of which is occupied by toxic metals. These metals widely distributed in the environment and of accumulation of a threat to human health. It is known, that cadmium and zinc at high concentrations have a negative impact on nature. In modern wastewater treatment technology we widely use polymeric sorbents with chelating properties. The use of polymeric chelating sorbents (PCS) usage allows separating individual or group trace elements from large volumes of solutions of complex composition, lowering the limit of detection, eliminating or reducing significantly the impact of macrocomponents which increases the cleaning efficiency. The article presents the results of a study of conditions of interaction of zinc (II) ions and cadmium (II) with PCT - polystyrene-azo-o-phenol-azo-rhodanine. We found the optimal values of the conditions for zinc (II) ions and cadmium (II) sorption. We investigated the effect of interfering of the macro- and micro- water components with the sorption of the ions studied. Maximum desorption of metal ions is achieved by washing the concentrate with 10 ml of 2M hydrochloric acid. The data indicate availability of the investigated sorbent for concentration and separation of zinc (II) ions and cadmium (II)

DAGESTAN HAWTHORN - A VALUABLE SOURCE OF BIOLOGICALLY ACTIVE SUBSTANCES
DescriptionThe article deals with hawthorn Dagestan. It is noted that the more than 100 species are found 14 species in Dagestan. The most common of them are studied as a source of biologically active substances and nutrients, and they can be used as food additives for various purposes. The content of biologically active substances and nutrients are defined. The high content of phenolic substances in C. pentagyna Waldst. et Kit, which play an important role in the formation of immunity and possessing P-vitamin activity is defined. Amino acid and fatty acid composition of the fruit of the hawthorn Crataegus pentagyna Waldst. et Kit, as the most valuable for using as food additives is defined by ionexchange and gas-liquid chromatography. Sixteen amino acids were identified and quantified in the protein component of hawthorn fruit. The high content of essential amino acids such as lysine, threonine, valine, methionine, leucine, isoleucine, phenylalanine. The amount of essential amino acids is 296.1 mg / 100 g. Chromatographic separation of fatty acid methyl esters has enabled us to establish the presence of the following fatty acids: palmitic, oleic, stearic, linoleic and linolenic, including established the presence of essential fatty acids - the family of alpha-linolenic acid OMEGA -3 and linoleic acid family of OMEGA -6
