Application of Supercomputer Technologies for Simulation of Socio-Economic Systems

To date, an extensive experience has been accumulated in investigation of problems related to quality, assessment of management systems, modeling of economic system sustainability. The studies performed have created a basis for formation of a new research area — Economics of Quality. Its tools allow to use opportunities of model simulation for construction of the mathematical models adequately reflecting the role of quality in natural, technical, social regularities of functioning of the complex socioeconomic systems. Extensive application and development of models, and also system modeling with use of supercomputer technologies, on our deep belief, will bring the conducted researches of social and economic systems to essentially new level. Moreover, the current scientific research makes a significant contribution to model simulation of multi-agent social systems and that isn’t less important, it belongs to the priority areas in development of science and technology in our country. This article is devoted to the questions of supercomputer technologies application in public sciences, first of all, — regarding technical realization of the large-scale agent-focused models (AFM). The essence of this tool is that owing to increase in power of computers it became possible to describe the behavior of many separate fragments of a difficult system, as social and economic systems represent. The article also deals with the experience of foreign scientists and practicians in launching the AFM on supercomputers, and also the example of AFM developed in CEMI RAS, stages and methods of effective calculating kernel display of multi-agent system on architecture of a modern supercomputer will be analyzed. The experiments on the basis of model simulation on forecasting the population of St. Petersburg according to three scenarios as one of the major factors influencing the development of social and economic system and quality of life of the population are presented in the conclusion

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.

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.

New insights into the Weichselian environment and climate of the East Siberian Arctic, derived from fossil insects, plants, and mammals

Multidisciplinary study of a key section on the Laptev Sea Coast (Bykovsky Peninsula, east Lena Delta) in 1998–2001 provides the most complete record of Middle and Late Weichselian environments in the East Siberian Arctic. The 40-m high Mamontovy Khayata cliff is a typical Ice Complex section built of icy silts with a network of large syngenetic polygonal ice wedges, and is richly fossiliferous. In combination with pollen, plant macrofossil and mammal fossils, a sequence of ca 70 insect samples provides a new interpretation of the environment and climate of the area between ca 50 and 12 ka. The large number of radiocarbon dates from the section, together with an extensive 14C database on mammal bones, allows chronological correlation of the various proxies. The Bykovsky record shows how climate change, and the Last Glacial Maximum in particular, affected terrestrial organisms such as insects and large grazing mammals. Both during the presumed “Karginsky Interstadial” (MIS 3) and the Sartanian Glacial (MIS 2), the vegetation remained a mosaic arctic grassland with relatively high diversity of grasses and herbs and dominance of xeric habitats: the tundra-steppe type. This biome was supported by a constantly very continental climate, caused by low sea level and enormous extension of shelf land. Variations within the broad pattern were caused mainly by fluctuations in summer temperature, related to global trends but overprinted by the effect of continentality. No major changes in humidity were observed nor were advances of modern-type forest or forest-tundra recorded, suggesting a major revision of the “Karginsky Interstadial” paradigm. The changing subtypes of the tundra-steppe environment were persistently favourable for mammalian grazers, which inhabited the shelf lowlands throughout the studied period. Mammal population numbers were lowered during the LGM, especially toward its end, and then flourished in a short, but impressive peak in the latest Weichselian, just before the collapse of the tundra-steppe biome. Throughout MIS 3 and MIS 2, the climate remained very favourable for the aggradation of permafrost. No events of regional permafrost degradation were observed in the continuous Bykovsky sequence until the very end of the Pleistocene

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

Reactogenicity of Biomaterials as Studied by Biochemical, Morphological and Ultrastructural Techniques

Reactogenicity is a characteristic of biocompatible materials that provokes the reparative and proliferative reaction of connective tissues, a compulsory stage of which is inflammation. Thus, reactogenicity studies should include experiments in vivo. A quantitative assessment of reactogenicity can be obtained by subcutaneous implantation of standard olive-shaped specimens covered by the biomaterial under study followed by biochemical, histological and scanning electron microscopical studies of the capsule developing around the implant. Reactogenicity of surgical threads is evaluated by semiquantitative histological analysis of the wound healing process after suture application. Biomaterial reactogenicity can be modified by changing the structure of the surface and its chemical characteristics, and in particular, by applying different biologically active substances including atrane-containing compounds. The reactogenicity indices suggested present the results of the interaction between the biomaterials and the cells
