Influence of environmental and geographical factor on the heavy metal content in the lungs of Hereford cattle

The problem of food contamination by heavy metals due to their accumulation in biosystems as a result of anthropogenic influences has been studied. The results of cadmium, lead, iron and manganese in cattle from the Novosibirsk Region and the Altai Territory are presented. The purpose of the study was to assess the impact of the ecological and geographical factor on the heavy metal content in the lungs of Hereford bulls. Lung samples were taken from 31 clinically healthy Hereford bulls aged 16-18 months. Sample preparation was carried out in accordance with GOST 26929-94 and 30178-96. The chemical composition of the samples was determined by atomic absorption spectrometry with flame and electrothermal atomization. The median values of the content of cadmium, lead, iron and manganese in the lungs of bull-calf were in the range of 0,01-0,12; 0,07-0,11; 70,9-89,1 and 0,3-0,4 mg/kg. The phenotypic variability of the level of iron and manganese was relatively low, while that of lead and cadmium was high. The dispersions of lead and cadmium levels in the animal groups studied were homogeneous, manganese and iron variants were heterogeneous. The influence of the ecological and geographical factor is characteristic only for cadmium levels. For manganese, iron, lead and cadmium the calculated reference ranges are: 0-1.12; 0-148.1 and 0-0.170 mg/kg respectively. They can serve as a guideline for Hereford cattle bred in the territories of Krasnozersky, Novosibirsky and Maslyaninsky districts of the Novosibirsk region and the Tselinny district of the Altai Territory.

The Late Neolithic of Trans-Urals: Poludenka issues

The paper examines the Poludenka discourse in the context of historiography and modern research practices. It analyzes changes in attributive characteristics and essential interpretation of Poludenka ceramics (culture, traditions) and the associated empirical and theoretical difficulties. It is noted that the problem of typological criteria is associated with the periodization paradigm the use of three- or two-stage periodization, which includes or excludes a transitional stage in the material culture of the Trans-Urals Neolithic between the early and late stages of development. The issue of the genesis of the Poludenka tradition and foreign cultural influence, as well as its local isolation on the southern periphery of culture, is also considered. It is assumed that the ornamental originality of the Poludenka pottery in the forest-steppe Pre-Tobol Region is associated with the interaction of the Trans-Urals population at the end of the Early Neolithic with the bearers of the Makhanjar tradition; emphasizes the participation of the Koshkino component in the Poludenka tradition creation at the previous stage. As a solution, it is proposed to return to the notion of a transitional stage between the Early and Late Neolithic, probably at the interval that coincides with the period of coexistence of all traditions, using the established term Kozlovo-Poludenka; the author also notes the perspective of material complexes analysis taking into account the geographical factor.

TRAVEL ROUTE PLANNING AND TRACKING APPS

The quality of a tourist trip depends on many factors, and one of the essential is route consistency route. This geographical factor influences the popularity, usefulness, efficiency and tourist travel safety. Drawing up logical routes requires not only a maximum of regional information, but also the developer experience. The creation of clear and convenient routes will allow for more organized tourism activities and reduce the chaotic load on the natural environment. Based on the analysis of applications for planning and tracking routes, this article focuses on the methodology for calculating the time of passage of multi-day cycling routes in main categories and solve the problem of symbiosis between geography and tourism practice. Article will talk about programs that will help you create a route and stick to it along the way.

Parliamentary Elections in Georgia in the Context of US Policy

The current parliamentary elections in Georgia have clearly demonstrated the fact that today Washington is becoming a key figure not only in the country’s foreign policy, but also in its internal political life. Under a new J.Biden administration it seems that Washington’s approach to Georgia, taking into account both countries’ special relationships as well as Georgian extremely favorable geopolitical/ geographical factor will become more proactive, which may greatly affect changes in the configuration of the entire South Caucasus.

Eurasian idea and cinema of Russian avant-garde

The paper traces connections of the works by Eurasian and Russian avant-garde directors Dzigа Vertov and Vsevolod Pudovkin. With this purpose it addresses сinematic creations of mentioned authors and teachings of Eurasian movement, especially by N. S. Trubetskoy. In his opinion, to analyze Russian history, one must take into account the geographical, political and economic components. He paid special attention to the geographical factor. The population of Russia-Eurasia includes various “human races”: both Slavic and Finno-Ugric peoples, as well as Turkic and Mongolian peoples. The Turan element occupies a significant part of the territory. Genghis-khan united all nomadic tribes under his sway and introduced Asian statehood in Russia. Moscow Rus form the basis of the Russian Empire after joining it former Golden Horde`s uluses. The views of N. S. Trubetskoy largely correlate with the ideas of avant-garde activists. The creations of the directors of the Russian avant-garde are also associated with the Asian theme. Eurasian ideas soaked up Soviet directors` minds and translated into culture, as well as into cinematic culture. Representatives of Russian avant-garde including D. Vetrov associated with futurists, LEF magazine and representatives of formal school, who in their turn were connected with Eurasians (R. Yakobson, for example). Eurasian teachings and avant-garde representatives` perceptions have common roots to be highlighted in Russian history. The scientific novelty of this study which involved comparative method is due to identifying similarities between them.

Natural-geographic factor in the historical process of the Adyghs

The desire to have a better grip of the history and to interpret the causes and nature of certain social phenomena is characteristic of humanity at all stages of development. Expansion of cognitive capabilities of historical research, the creation of new units in the mental lexicon allow us to increase the range of vision of history, to give the understanding of the past a holistic, more capacious understanding. Translation of history in the context of many sciences creates resources for the emergence of generally accepted attitudes into a different semantic dimension, filling them with more weighty argumentation. In the modern scientific space historical geography appears to be a promising territory, given a certain conditionality of the development of society at all stages of the existence influenced by the natural-geographical factor. In the early stages of human development the existence of people depended on the characteristics of nature to a much greater extent than today. Nevertheless, modern civilization, despite the scientific progress, has not managed to distance itself from the influence of nature and is still interconnected with it by many threads. This general situation is fully true for the Circassians, the borders of the territory, which were deliberately created by nature itself for the conservation of the population within its natural limits. In this regard, the subject of the research is the problem of the influence of the natural-geographical factor on the historical process of the Circassians. The object of the research is the peculiarities of the geography of the region, reflecting the degree of the role of the natural environment in the formation of the Adygh ethnos. The aim of the research is to analyze the nature of the interaction and conditionality of the Adygeyan history by the natural environment, rightfully recognized as one of the most ancient and unique cradles of the landscape map of our country. To achieve this goal tasks were set related to the analysis of the content, orientation and mediation of the progressive development of the Circassians by the peculiarities of the natural environment. In this research the understanding of the sought problem is based on the ideas of major philosophers, historians, sociologists, and cultural scientists. The research methodology is based on the principles of historicism and objectivity, which allows us to see new facets in understanding many phenomena of the Adyghe history, to give them a value characteristic.

Najnowszy stereotyp Ukraińca w środowisku studentów poznańskich i lubelskich

The article analyses the contemporary image of a Ukrainian in the linguistic picture of the world as perceived by students from Poznan and Lublin. Based on the results of the questionnaire with the geographical factor, the article distinguishes the “naive” cognitive definitions, methods of categorisation, traits of a typical Ukrainian and their aspect, which all differ depending on the geographical location of the two cities. The article analyses which subjects, according to students from different regions of Poland, are characteristic of a Ukrainian and how the geographical factor influences their dominance in the light of different aspects.

Geographical Factor in Regional Development

Regional development of Russian regions is characterized by a high level of heterogeneity. Researchers highlight a significant number of factors affecting the level of regional development. Geographical factor is recognized as one of the most important factors. The development of border regions is similar to that of Russian regions. The purpose of the research is to determine the differentiation of border regions and to study the dynamics of its change. The object of the research is border regions united in the system. The process of unification of regions is based on geographical location. The subject of the study is the process of regional differentiation. Methods of assessing the convergence of economic entities are the instrument of researching regional differentiation of border regions. The convergence theorem analyzes the interregional differentiation of border regions and considers the possibility of their convergence. As a result of using convergence approaches based on the definition of convergent processes, the coefficient of variation is calculated. On the basis of the calculated values of the coefficient and its change, the possibility of convergence of border regions is assessed and the process of change of interregional differentiation is analyzed. Another direction, on the basis of which the analysis of regional heterogeneity of border regions is based, is the determination of the differentiation coefficient, which allows to determine the level of the gap between polar groups of regions. The goal set in the study will allow assessing the impact of geographical location on economic development and formulating directions of economic policy. Spatial heterogeneity of border regions defined by means of mathematical tools can be used when writing the Program and the Strategy for Regional Development, within which one of the competitive advantages will be the location of the territory.
