Formation Conditions And Debris Flow Regime In Jiangjia Ravine, Yunnan, China – Applicability Of Russian Methodology

The requirements of the debris flows’ parameters assessments vary from country to country. They are based on different theoretical and empirical constructions and are validated by data from different regions. This makes difficult comparison of the reported results on estimated debris flows activity and extent. The Russian normative documents for the debris flows’ parameters calculations are based on empirically-measured parameters in wide range of geological and climatic conditions at the territory of former USSR, but still not cover all the possible conditions of debris flow formation. An attempt was made to check applicability of the Russian empirical constructions for the conditions of the debris flows formation in Yunnan, China, where unique long-term dataset of debris flows characteristics is collected by the Dongchuan Debris Flow Observation and Research Station. The results show, that in general the accepted in Russia methodology of calculation of the parameters of debris flows of certain probability corresponded well to the observed in Dongchuan debris flows characteristics. Some discrepancies (in the average debris flow depth) can be explained by unknown exact return period of the actually observed debris flows. This allowed to conclude that the presently adopted empirical dependencies based on country-wide (USSR) empirical data can be extrapolated up to the monsoon climate and geological conditions of Yunnan province.

THE INFLUENCE OF MIGRATION PROCESSES ON THE FORMATION OF THE URBAN OBJECT STRUCTURE

In the article was found that the planned location of new or expansion of existing production clearly coincided with the movement of certain segments of the population to these regions for employment, examining and analyzing the problems of migration of the population of the former USSR. The researches of the Russian town-planners Bocharov Y.P., Belousov V.M., Vladimirov V.V., Maloyan G.A., Lezhava I.G. and other are devoted the problems of development of the theory of settlement with loss of planning component in development of systems of settlement and general plans of cities in new market (social and economic) conditions. Leading domestic urban planners have devoted their research to the problems of the development of the theory of settlement in Ukraine, the system of settlement and the development of master plans in modern market conditions (1992-2014). Some of them are Filvarov G.K., Yezhov V.I., Demin M.M., Lavrik G.I., Repin V.M., Timokhin V.O., Shkodovsky Y.M., Rudnitsky A .М. and other. The article presents the stages of formation of production relations, social, economic, architectural and spatial evolution under the pressure of migration processes, based on the analysis and research: The formation of the labor market (places of employment) in the development of industry, transport links and resettlement (early nineteenth - early twentieth century). Urbanization of cities in the early twentieth century due to migrations (free labor) from near and far agglomerations. Urbanization of the late twentieth century due to the release of labor (the collapse of the collective and state farm system). Under the pressure of migration and transport processes the compositional and planning spatial structure of the city is determined by the following aspects: the hierarchy of the city in the general network of settlements; the level of the city's public transport network; mobility of city residents; location of attractive objects for migrants in the city planning structure; socio-demographic characteristics of residents. Territories of cities with developed production are becoming the poles of industrial industry with the latest technologies, as well as centers of business.

The Use of Innovative Contact Strip for Pantographs of Electric Rolling Stock. Experience in Operational and Bench Tests

Modern high-tech composite materials are widely used in various sectors of the economy, in particular, in railway transport. Among the areas of application of such innovative materials, the manufacturing of contact strips for pantographs of electric rolling stock should be mentioned. Innovation is primarily understood as the self-lubricating property of the working surface of the linings. The linings made of such materials differ from the traditional graphite (coal) ones by the increased content of metal additives, in particular copper, which limits the possibility of their use on electric rolling stock in the countries of the European Union. Regulatory restrictions on the content of copper (35% and 40%) are associated with possible damage to the contact wire, in the case of using overlays with a content of copper (metals) greater than these restrictions. On the railways of Ukraine (countries of the former USSR), there are also restrictions on the use of linings of different types according to the degree of wear of the contact wire, no more than 40 microns is allowed per 10 thousand passes of the locomotive pantograph along the contact wire. These standards are verified during operational and bench tests. The aim of the article is to present the types of tests and compare the obtained values with similar indicators in the case of using a traditional contact strip for pantographs of electric rolling stock. The results obtained confirm the possibility of using innovative linings on iron networks, since the wear of the contact wire during testing is much lower than that of the normative and knife than for traditional types of linings. In addition, during a set of tests, the fact of improving the quality of the working surface of the contact wire was established, which positively affects the extension of the service life of the contact wire.

Geopolityka regionu Morza Czarnego a Unia Europejska

The geopolitical rivalry and the clash of interests between the superpowers have been present in the Black Sea region for centuries. During the Cold War when the East-West divide was at its height, the Black Sea was “excluded” from geopolitical competition between the superpowers as it became the domain of mainly one player – the Soviet Union. The dismantling of the Pax Sovietica and the subsequent collapse of the Cold War gave rise to a new geopolitical situation in the Black Sea region. The former USSR was superseded by the Russian Federation and other political entities independent from Russia, yet having strong bonds with the region both in terms of geography and their political and cultural interests. These were new states like Ukraine, Moldova, Georgia, Armenia and Azerbaijan, but also former Soviet satellite states such as Bulgaria and Romania. In other words, the collapse of the USSR entailed the emergence of a new system of geopolitical power in the post-Soviet space.

Sequence Variability of pXO1-Located Pathogenicity Genes of Bacillus anthracis Natural Strains of Different Geographic Origin

The main pathogenic factor of Bacillus anthracis is a three-component toxin encoded by the pagA, lef, and cya genes, which are located on the pXO1 plasmid. The atxA gene, which encodes the primary regulator of pathogenicity factor expression, is located on the same plasmid. In this work, we evaluated the polymorphism of the pagA, lef, cya, and atxA genes for 85 B. anthracis strains from different evolutionary lineages and canSNP groups. We have found a strong correlation of 19 genotypes with the main evolutionary lineages, but the correlation with the canSNP group of the strain was not as strong. We have detected several genetic markers indicating the geographical origin of the strains, for example, their source from the steppe zone of the former USSR. We also found that strains of the B.Br.001/002 group caused an anthrax epidemic in Russia in 2016 and strains isolated during paleontological excavations in the Russian Arctic have the same genotype as the strains of the B.Br.CNEVA group circulating in Central Europe. This data could testify in favor of the genetic relationship of these two groups of strains and hypothesize the ways of distribution of their ancestral forms between Europe and the Arctic.

The Post-Soviet Space and Turkey: The Results of 30 Years

The article scrutinizes the main results of the 30-year independent existence of the former Soviet republics under the conditions of modern political realities and the formation of a polycentric system of international relations, where regional states such as Turkey begin to exert an increasing influence on the ongoing processes. Based on the results of the analysis, the author comes to the conclusion that since the collapse of the Soviet Union, two trends have developed in the post-Soviet space: integration and disintegration. e main task of the Republic of Turkey in the post-Soviet region is to set the pro-Turkish model of integration of key Turkic states and to create the so-called “Turkic world” – a new subsystem of international relations under its auspices. In order to implement these plans, Ankara pursues three main goals in the post-Soviet space: to replace the “Turkic” with the “Turkish”; secondly, to bring loyal elites to power in the partner countries; and to concentrate the movement of resources within the framework of the “hub” ideology. Meanwhile, during its interaction with the former USSR countries Turkey has passed or is still passing through several stages: the “era of hope”, the “step-by-step era” and the “era of Turkish-centric integration”, which continues up to the present time and is expressed in exerting a significant influence on the Turkic actors.

Comparing the Different Manifestations of Postpartum Mental Disorders by Origin, among Immigrants and Native-Born in Israel According to Different Mental Scales

We conducted a prospective study, aimed to study whether the prevalence of mental disorders after birth differs by country of origin. Parturient mothers of Ethiopian origin, Former-USSR (FSU) origin, or nonimmigrant, native-Israeli origin (n = 974, all Jewish) were recruited in hospitals in Israel and were followed 6–8 weeks and one year after birth. General linear models were used to study the associations between origin and mental health, comparing Ethiopian and FSU origin with native-Israeli. Ethiopian and FSU mothers were more likely to report on somatic symptoms, compared with native-Israeli women. Ethiopian origin was negatively and significantly associated with anxiety in all three interviews (β = −1.281, β = −0.678 and β = −1.072, respectively; p < 0.05 in all). FSU origin was negatively associated with depression after birth (β = −0.709, p = 0.036), and negatively associated with anxiety after birth and one-year postpartum (β = −0.494, and β = −0.630, respectively). Stressful life events were significantly associated with all mental disorders in the three time points of interviews. Our findings suggest that immigrants tend to express higher mental distress with somatic symptoms. Additional tools are needed for mental distress screening among immigrants.

DOCUMENTS ON THE HOLODOMOR OF 1932–1933 IN THE KHERSON REGION

Purpose and methodology of the study. The article is devoted to the analysis of sources on the history of the Holodomor of 1932–1933 in the Kherson region. The results of the study will help to expand knowledge about the famine of 1932–1933 and to conduct an effective search for new archival information about this event. The study is based on source methods of identifying, analyzing and evaluating sources. Methods of archival heuristics are used, with the help of which a circle of archives is established, where the necessary information could potentially be stored, based on information about fundraisers.Results and scientific novelty of the study. A significant array of official records was analyzed: orders, reports, information, correspondence, certifying the crime of the Soviet government against the Ukrainian people - the Holodomor genocide of 1932–1933 in the Kherson region.It was found that the collections of archival documents of Russian archivists, despite the purpose of preparing a source complex, the composition and content of which would deny the Holodomor as genocide of the Ukrainian people, nevertheless contain valuable information from the central archives of the former USSR, including materials about southern Ukraine. One of the significant shortcomings is the lack of documents that would reflect the reaction of the "fraternal" republics to the famine in Ukraine, as Kherson trade unions, in particular, sought food aid from the relevant authorities in Belarus and Russia.In Ukraine, in parallel with the processes of declassification of archives, collections of documents with high-quality archeographic design were also published. In fact, Ukrainian scholars have urged their Russian counterparts to address the issue of famine, as they have previously produced high-quality informational content for the study of the Holodomor in Ukraine, which cannot be ignored.Regional archives play an equally important role in forming the source base of the problem. Their materials have been repeatedly published, including in the large-scale project "National Book of Remembrance of the Holodomor Victims of 1932–1933 pp. in Ukraine” (2008). It seemed that such a number of identified, published, including in the form of Internet resources of documentary monuments, cartographic materials, sources on demographic statistics has already exhausted the subject, but declassification and transfer of documents from the SBU continues, and archives are replenished with new documents. In particular, those that raise the issue of Soviet repression for spreading information about the famine of 1932–1933 in later years. That is, the discovery of new documents and the setting of new research tasks to study the history of the Holodomor is a real prospect for the future.Key words: Holodomor, Kherson region, local history, archive, source, document. Мета та методологія дослідження. Стаття присвячена аналізу джерел з історії Голодомору 1932–1933 років на терито-рії Херсонщини. Результати дослідження допоможуть розширити знання про голод 1932–1933 років та проводити ефективний пошук нової архівної інформації про цю подію. В основі дослідження лежать джерелознавчі методи виявлення, аналізу та оцінки джерел. Застосовуються методи архівної евристики, за допомогою якої встановлено коло архівів, де потенційно могла зберігатись необхідна інформація, виходячи з інформації про фондоутворювачів. Результати та наукова новизна дослідження. Проаналізовано значний масив документів офіційного діловодства: накази, доповідні записки, інформації, листування, що засвідчують злочин радянської влади проти українського народу – Голодомор-геноцид 1932–1933 років на території Херсонщини.З’ясовано, що збірники архівних документів російських архівістів, не зважаючи на мету підготувати джерельний комплекс, склад і зміст якого заперечуватиме Голодомор як геноцид українського народу, тим не менш містять цінну інформацію з центральних архівів колишнього СРСР, в тому числі матеріали про Південь України. Одним з суттєвих недоліків – відсутність документів, що б відображали реакцію «братніх» республік на голод в Україні, оскілки зокрема херсонські профспілки звертались за продовольчою допомогою до відповідних органів в Білорусії та Росії. В Україні, паралельно з процесами розсекречення архівів, також видано збірки документів з якісним археографічним оформленням. Власне українські вчені спонукали російських колег звернутись до теми голоду, оскільки раніше за них сформували якісний інформаційний контент для вивчення Голодомору в Україні, котрий не можливо ігнорувати.Не менш важливу роль у формуванні джерельної бази проблеми відграють регіональні архіви. Їхні матеріали неодноразово публікувались, в тому числі в масштабному проєкті «Національна Книга пам’яті жертв Голодомору 1932–1933 pp. в Україні» (2008). Здавалось, така кількість виявлених, опублікованих, в тому числі – у вигляді Інтернет-ресурсів документаль-них пам’яток, картографічних матеріалів, джерел з демографічної статистики вже вичерпала тематику, проте розсекречення та передача документів з СБУ триває, й архіви поповнюються новими документами. Зокрема, такими, що піднімають питання репресій радянської за поширення інформації про голод 1932–1933 років у пізніші роки. Тобто виявлення нових документів, і постановка нових дослідницьких завдань з вивчення історії Голодомору – реальна перспектива на майбутнє.Ключові слова: Голодомор, Херсонщина, локальна історія, архів, джерело, документ

Harmfulness of giant Heracleum hogweed and methods of their control

Goal. Analysis and generalization of domestic and foreign experience on the invasion and harmfulness of giant hogweeds, including Sosnowski’s heracleum Sosnowskyi Mandenova to disseminate scientifically sound information on practical methods of control and prevention of further spread of giant hogweed, promoting biological conservation. Methods. System-analytical, abstract-logical, empirical. Results. According to research, scientists have predicted that the penetration of alien species into new territories is constant. However, more and more these processes are intensified under the influence of human activity. A clear example of this is the situation with giant hogweed. Imported into Western Europe in the XIX century as an ornamental plant Borage Mantegazzi today poses a real threat to the ecosystems of almost all countries of the European continent. The seeds of the London population of Persian borage were sown in 1836 by English gardeners in northern Norway, from where it quickly spread throughout the Scandinavian countries. In the former USSR in the postwar years, Sosnowski’s hogweed was actively studied and implemented, which has now become widespread in the natural ecosystems of the CIS countries and Ukraine in particular. Conclusions. According to research, scientists have predicted that giant hogweed poses a great danger and threatens the natural ecosystems of our country and the West, control of Mantegazzi hogweed will be much more difficult and costly than with Sosnowski hogweed. For this reason, it is essential to take preventive measures to locate and remove plants of very dangerous invasive species and other species with a polycarpic cycle of development, as well as to prevent their widespread spread.
