MODERN ANALYSIS METHODS USE IN ORDER TO ESTABLISH THE GEOGRAPHIC ORIGIN OF FOOD PRODUCTS

Food products with controlled geographical origin place are in special demand among consumers because of their specific properties, due to climatic, soil characteristics or other factors. The article provides an analysis of regulatory framework for legal goods protection with an indication of their origin place on the territory of the Russian Federation and in other countries. Existing authentication methods for this type of product are reviewed. Based on the analysis of scientific literature, the authors noted the most significant works aimed at confirming the authenticity of food products’ origin place on the example of honey and meat products, which were carried out in the countries of the European Union, Australia, China, Brazil, South Africa, the USA and other countries. It is shown that the most widespread researches aimed at studying values of isotopic ratios of hydrogen (2H/1H), carbon (13C/12C), oxygen (18O/16O), nitrogen (15N/14N) and sulfur (34S/32S) in compounds contained in products that reflect the distribution of «light» and «heavy» isotopes during biological and geochemical processes within a single region. The analysis of the works aimed at studying the qualitative and quantitative composition of trace elements and rare earth metals (As, B, Ba, Cd, Li, Mn, Pd, Rb, Se, Te, Tl, Dy, U, etc.), as well as research of isotopic relations values of some elements (87Sr/86Sr, 207Pb/206Pb, etc.) in product samples and soils of studied region. The advantages of an integrated research approach, which includes the creation of data array of various indicators values and its in-depth analysis using chemometric algorithms and mathematical modeling methods, are shown.Food products with controlled geographical origin place are in special demand among consumers because of their specific properties, due to climatic, soil characteristics or other factors.

The study of destruction of the compositions restoring the dentition integrity under uniaxial tension

Using vital teeth as supports for non-removable prostheses has a known beneficial effect on the rehabilitation of patients suffering from partial adentia. In this case, dentinal tubules remain exposed after their preparation, which leads to tooth hypersensitivity. At the same time, the effects of chemical and physical agents, as well as bacteria and their metabolic products may promote the development of pulpitis of teeth being a part of orthopedic structur

RATIONAL USE OF THE SECONDARY RESOURCES OF THE VINEYARD AND WINEBRANDING INDUSTRY

In the grape processing, secondary resources are primarily the remnants of the generative plant organs (berries) — sweet and fermented husks of grapes, seeds, peels, etc. However, the use of vegetative organs — vines, which are more promising, of grape leaves is promising. It is shown, that red leaves of grape are a source of phenolic compounds, resveratrol and other antioxidants, and also contain activators of enzymes, that cause venotonic and angioprotective properties. The most valuable in this respect are red grape leaves, which grow in covering areas, because on the eve of winter, as a defense against the cold, they accumulate a greater amount of resveratrol. The use of CO2 -extraction technology in the processing of red leaves makes it possible to obtain extraction cake with a high content of biologically active substances due to the destruction of the cell structure during the extraction process. At the same time, the hydrophilic extract of the extraction cake after CO2 -extraction has the greatest value, it is well soluble in water and is intended to enrich the soft juice based on grape juice with biologically active substances. A technology was developed for using CO2 extracts of grape seeds to stabilize margarine emulsions against oxidation and to increase the thermal stability of frying fats.In the grape processing, secondary resources are primarily the remnants of the generative plant organs (berries) — sweet and fermented husks of grapes, seeds, peels, etc. However, the use of vegetative organs — vines, which are more promising, of grape leaves is promising.

Integral assessment of the social and economic development of megacities in Russia

The relevance of the analyzed issue is due to the existing need for more attention to the problems of large cities, which are the social and economic centers that perform important functions and realize the interests of the population, business and local government. The purpose of this article is to disclose the sources of the urban growth and development, the integrated assessment of the size and spatial distribution of the economic activity, regional planning and the government activity. The leading approaches to the study of this issue are systemic and reproduction, which, along with the use of econometric modeling and statistical analysis, allowed revealing significant shortcomings of the institutional urban management mechanism and proposing a number of measures to correct these shortcomings. The article illustrates the theoretical basis of modeling of large cities as spatial economic systems, determines their sources of growth, gives the characteristic features of the urban development in modern conditions, and proposes a conceptual model of a modern city. The contents of the article may be useful for the development of social and economic development strategies both the urban district, and the region as a whole, since large cities act as a locomotive, and they move the regional economy in the direction of the social and economic well-being. © 2016 Malikh et al

Pragmatic aspect of switching of codes in texts of an advertizing discourse

The article deals with the pragmatic analysis of code switching on the basis of comparative study of advertising discourse texts in English, French and Russian in order to find out current trends in the use of the dominant foreign pragmonyms in advertising texts. In determining a communicative intention of the sender of advertising messages the pragmalinguistic analysis allowed to establish basic and extended switching functions. By applying the methods of generalization and comparison, the component and contextual analysis of the language units as part of the context in different matrix languages, the selection of the advertising text, often subjected to code switching, have been identified. Thus, systematization of structural features of code switching in advertising discourse in different languages presented in the study contributes to developing translation aspects of advertising messaging, as well as issues of multilingualism in sociolinguistics. In addition, the analysis of pragmatic functions of switching and structural models and linguistic appearance of pragmonyms allows to more competently create and edit advertising texts for specific target audiences. In general, the technology of the study of the advertising text for linguistic code switching opens further prospects for comparative analysis in this area based on the material of other genres and discourses to more accurately identify pragmatic functions of present code changes

Microparticles prepared from biodegradable polyhydroxyalkanoates as matrix for encapsulation of cytostatic drug

Microparticles made from degradable polyhydroxyalkanoates of different chemical compositions a homopolymer of 3-hydroxybutyric acid, copolymers of 3-hydroxybutyric and 4-hydroxybutyric acids (P3HB/4HB), 3-hydroxybutyric and 3-hydroxyvaleric acids (P3HB/3HV), 3-hydroxybutyric and 3-hydroxyhexanoic acids (P3HB/3HHx) were prepared using the solvent evaporation technique, from double emulsions. The study addresses the influence of the chemical compositions on the size and ξ-potential of microparticles. P3HB microparticles loaded with doxorubicin have been prepared and investigated. Their average diameter and ξ-potential have been found to be dependent upon the level of loading (1, 5, and 10 % of the polymer mass). Investigation of the in vitro drug release behavior showed that the total drug released from the microparticle into the medium increased with mass concentration of the drug. In this study mouse fibroblast NIH 3T3 cells were cultivated on PHA microparticles, and results of using fluorescent DAPI DNA stain, and MTT assay showed that microparticles prepared from PHAs of different chemical compositions did not exhibit cytotoxicity to cells cultured on them and proved to be highly biocompatible. Cell attachment and proliferation on PHA microparticles were similar to those on polystyrene. The cytostatic drug encapsulated in P3HB/3HV microparticles has been proven to be effective against HeLa tumor cells.Russia (Federation) (Agreement 11.G34.31.0013)Program of the President of Russia for Young Doctors of Sciences (Grant MD-3112.2012.4
