    Full Text Available Researches of geology and composition of silicate-carbonate rocks of the Ukrainian shield. Concluded that they belonged to the karbonatites of the normal series. Metallogenic characteristics and specialization are confirming to the magmatic origin and resemblance with karbonatites alkaline series. In connection with the prevalence in the Precambrian ultrabasic-basic formation of carbonatites magmatism it was, seems to be more widespread in the areal extent of the ancient protoplatforms and rift zones. Numerous experimental data explicitly confirm the possibility of origin of dolomite melts of peridotite magma at its saturation pressure of CO2 and more than 5.7 GPa. Determined formational belonging and potential metallogenic specialization of silicate-carbonate rocks, associated with ultrabasic complexes of the Ukrainian Shield. Particular attention is paid to the identification of features that silicate-carbonate rocks can be attributed to magmatic or metamorphogenic-sedimentary formations, compared to their material composition and geotectonic position. As a result, identified the main characteristics for their recognition. Of these, the leading classified geotectonic, structural-geological, petrographic and mineralogical features, material composition and structure of the silicate-carbonate rocks associated with them relations of ultrabasic, mineralogical and geochemical features and communication with the manifestations useful mineralization. When you select features also include the effect of metamorphism on the nature of the transformation of carbonate-ultrabasic massifs and their modern look at this level erosion of the crust.

    The results of Sm-Nd isotope investigation of rocks of the Ukrainian shield anorthosite-granite association are described; this association, according to the geologic data, is the latest association in a seriesof self-contained anorthosited. The latters are connected with considerable masses of rapakiwi-granited. Isotope analysis is carried out by mass spectrometry. Isotope ratios /sup 147/Sm//sup 144/Nd and /sup 143/Nd//sup 144/Nd for five samples investigated are presented. Isotope data obtained are marked to be important information about the origin of rocks studied. Evident age difference of granite and basic components of the association is established, that idnores the possibility of the rock formation during crystallization differentiation. The basic value of the radiometric 1.89-1.74 milliared years age of the Ukrainian shield anorthosites lied in the fact that these data confirm once more the specific nature of the earth's crust evolution especially at early stages of its formation.

    Full Text Available Two rare metal leucocratic granites, Perga and Kamennaya complexes, can be distinquished on the Ukrainian shield. The Perga complex consists of medium- and coarse grained, mainly porphyric, biotite, riebeckite and aegirine granites, granite porphyries, microclinites and albitites with rare metal mineralization (genthelvite, phenacite, tantalite, cassiterite and wolframite etc.. Granites from several stocks (up to 30 km2 in the northwestern part of the shield, situated along the fracture zone, restricted the large Korosten pluton of rapakivi granites to the northwest. The age of these granites (Pb-Pb and U-Pb methods on zircon and monazite practically coincide with the age of rapakivi granites being 1750 Ma. Within the Korosten complex of rapakivi granites we consider that zinnwaldite granites, which are characterized by fluorite and topazine mineralization, represent the final phase of pluton. These granites differ from the Perga ones by their low content of rare metals. The Kamennaya Mogila complex lies in the southeastern part of the Ukrainian shield. It consists of biotite and muscovite-biotite, medium- and coarse-grained (also porphyric, and occasionally greisining granites with rare metal mineralization (cassiterite, columbite, molybdenite, wolframite and beryl. Granites form several stocks (5-30 km2 situated 10-30 km to the west-northwest of the South-Kalchik gabbro-syenite-granite pluton. Granitoids in both of these complexes have similar isotopic ages (1800 Ma. Leucocratic subalkaline granites (the Novoyanisol type are known within the pluton itself, occupying an intermediate position between the above mentioned in terms of mineral and geochemical composition. The gabbro-syenite-granite formation of the Nearazov region has a substantial similarity to the anorthosite-rapakivi-granite formation. In this respect the relation of each of them to rare metal granites is rather remarkable. This relation is, most probably, not only spatial, but

    In this work there are presented the general data on the study of thermal and radiation effects in minerals separated from rocks of the Ukrainian shield. These minerals (quartz, feldspar, amphiboles, apatite, biotite, kaolinite, etc.), exposed by doses 10 4 , 10 6 , 10 8 Gy by Co 60 source, were studied by a complex of physical methods. Special attention was given to the study of radiation defects formation (electron-hole paramagnetic centres, OH- groups destruction, changes in a charge state of ions) in a mineral structure. The mentioned radiation defects were used in the extrapolation method. The connection between structural peculiarities of minerals (containing uranium and thorium) and processes of their metamyctization are considered. It is demonstrated that the minerals, which have large channels or interlayer spaces in their structure, as a rule, are not metamyct. Using the spectroscopic methods of the extrapolation it is shown that the crystalline massifs, which do not have detectable amounts of hydroxyl containing minerals (biotite, amphibole, etc.) and ions Fe 2- , are perspective for long-lived radioactive wastes (RAW) dumping. As it follows from obtained results, the rocks, containing minerals with OH- groups and gas-liquid inclusions, should be considered as the 'mineral-water' system. (author)

    2017-01-01

    This short review deals with the problem of individualistic/collectivistic orientation in the Ukrainian population. It is thought that individualism is a striking feature of the Ukrainian national character. This was repeatedly stressed by some distinguished Ukrainian thinkers. Many interesting examples of individualistic behavior can also be found in Ukrainian proverbs and sayings. At the same time, some authors argued for deep collectivistic roots of the Ukrainian culture. Researches that h...

    Full Text Available The history kept for us names of the first Ukrainian, arrived to Canada in 1891. These are residents of the village of Nebylov in the Western Ukraine Ivan Filippov and Vasily Elenyak. The Ukrainian immigration to Canada gains mass scope only after 1896, in many respects thanks to efforts of the galitsky agronomist Osip Oleskov who sent a big flow of the Ukrainian immigrants from villages of the Western Ukraine instead of Brazil to Canada. During the first wave of the Ukrainian immigration to Canada which is considered the largest and occurred between 1891 and 1914, in the country lodged more than 170 thousand Ukrainian. The second wave of Ukrainian immigration to Canada occurred in the interwar period, especially between 1924 and 1930. The third wave of Ukrainian immigration to Canada was due to political reasons and lasted from 1947 to 1954. Many of these immigrants were political refugees, which made this wave overtly politicized. In the early 1990s began the fourth wave of Ukrainian immigration to Canada, which continues today. This wave was related mainly to economic reasons.

  10. Ukrainian-Russian Mixed Speech “Suržyk” within the System of Ukrainian and Russian Interaction

    2015-12-01

    Full Text Available The question of different forms of real and/or presumed mixed speech, a consequence of the interaction between Ukrainian and Russian and widely known as “Suržyk,” remains central in much of contemporary Ukrainian and, more widely, East Slavic sociolinguistic and language contact research. This article pursues a twofold aim: first, I intend to reaffirm my personal hypothesis on the formation process of this mixed speech, which has at times been cited without attribution in the scholarly literature. Second, the paper aims to examine the functioning of Ukrainian-Russian Suržyk within a broader sociolinguistic framework that takes into account other forms of language interaction. Ukrainian-Russian mixed speech in fact has to be assessed and separated from other factors, such as the Ukrainian variety of Russian, dialects, etc. This approach has rarely been applied in previous studies on the topic. The role played by current language ideology is a further essential aspect in establishing which language elements should be attributed to Ukrainian-Russian Suržik. This undoubtedly affects the average speaker’s judgment about the degree of authenticity of Ukrainian forms. One can note a tendency to restrict the synonymic potential of Ukrainian in favor of lexemes and constructions that are dissimilar to Russian. This situation tends to alter the language consciousness of younger generations of Ukrainian speakers, who are likely to perceive as Russian (and therefore part of the Ukrainian-Russian mix elements that are in fact authentic Ukrainian speech elements. These and other related aspects will be the object of my discussion.

    Full Text Available The analysis of archival sources, published memories of the corypheus (the leading actors of the Ukrainian theatre Marko Kropivnitskiy, Larisa Staryts’ka-Chernyakhivs’ka, Sofia Tobilevych, materials of the periodical press (the newspapers «Trud», «Zarya», «Kievlianin» allowed to examine the question of the first performance by the Ukrainian Professional Drama Theatre the play «Nazar Stodolya» by Taras Shevchenko in Kyiv in January 1882. The question of what preceded and caused the holding of the first performance in the Ukrainian language by the Ukrainian Professional Drama Theatre in January 1882 in Kyiv was investigated. The importance of this event for the Ukrainian society and the development of the Ukrainian Professional Drama Theatre as a whole was revealed. It is noted that in her memories L.M. Staryts’ka-Cherniakhivs’ka emphasized the value of the performance of Ukrainian Professional Drama Theater in Kyiv for the Ukrainian community. She wrote that the spectators filled the lobby and corridors, faces of all present viewers were burning from ardor and enthusiasm, their eyes were shining, there was a lively noise, the native Ukrainian language rang everywhere in the theater.  She noted that the spectators were dressed in Ukrainian national clothes, there were visible bright suits of Ukrainian women in the theater lodges, many children and parents were dressed in Ukrainian costumes in the theater lodges, there could be heard everywhere the native Ukrainian language in the theater. There was the abundance of the heart everywhere. It is found that the partial lifting of restrictions on the Ukrainian staging plays in 1881, made possible for Kyiviets to see the first performance of the Ukrainian Professional Drama Theatre in the Ukrainian language in 1882. It is found that the very first performance of the play «Nazar Stodolya» by the Ukrainian professional actors’ troupe consolidated the Ukrainian speaking Kyiviets and

    Full Text Available Raising of problem. In modern Ukrainian society, which is undergoing a national renaissance, greatly deepened interest in the symbols of material and spiritual culture as a form of identification and identity. Inseparable from life as language, song, were and are proverbs and sayings. As an expression of acute intelligence people, aesthetic preferences, high morality, humor, accuracy, wit and strength, wisdom and beauty of poetic language, they accompany mankind from antiquity and enrich the new generation. Valuable signs of Ukrainian culture proverbs are also the fact that generally have exemplary character, as giving advice, caution, warn, approve, condemn. Based on rich experience, proverbs reflect all sectors of the Ukrainian people, especially bright life, habits, lifestyle and mentality. The most important element of life without which you cannot imagine life before and today is the house - the personification of his native home, family, independence, well-being and hospitality. In the beginning attached great importance to the house, she was treated with great respect, ordered decorated holiday and protected. It found expression in many proverbs and sayings. These samples of folk wisdom affecting the eternal themes so do not lose their relevance today. Their research makes it possible to understand the deeper spirituality, especially the outlook of the Ukrainian people. Purpose. To find out the semantics of the component "khata" in the proverbs and sayings identify productivity in shaping Ukrainian folklore. Conclusion. Proverbs and sayings of the component "hut" reflect various spheres of life Ukrainian: the organization of life, family relationships, moral and ethical code, mentality, especially social relations. Home is inseparable from its inhabitants, becoming masters of character, its appearance characterizes the attitude of the hosts it, the house represents those relationships that have developed between family members

    2013-05-01

    Sedimentary-migration origin theory of hydrocarbons dominates nowadays. However, a significant amount of hydrocarbon deposits were discovered in the crystalline rocks, which corroborates the theory of non-organic origin of hydrocarbons. During the solving of problems of oil and gas exploration in crystalline rocks and arrays so-called "direct" methods can be used. These methods include geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) (FSPEF-VERS express-technology). Use of remote Earth sounding (RES) methods is also actual. These mobile technologies are extensively used during the exploration of hydrocarbon accumulations in crystalline rocks, including those within the Ukrainian crystalline shield. The results of explorations Four anomalous geoelectric zones of "gas condensate reservoir" type were quickly revealed as a result of reconnaissance prospecting works (Fig. 1). DTA "Obukhovychi". Anomaly was traced over a distance of 4 km. Approximate area is 12.0 km2. DTA"Korolevskaya". Preliminary established size of anomalous zone is 10.0 km2. The anomalous polarized layers of gas and gas-condensate type were determined. DTA "Olizarovskaya". Approximate size of anomaly is about 56.0 km2. This anomaly is the largest and the most intense. DTA "Druzhba". Preliminary estimated size of anomaly is 16.0 km2. Conclusions Long experience of a successful application of non-classical geoelectric methods for the solving of variety of practical tasks allow one to state their contribution to the development of a new paradigm of geophysical researches. Simultaneous usage of the remote sensing data processing and interpretation method and FSPEF and VERS technologies can essentially optimize and speed up geophysical work. References 1. S.P. Levashov.

  20. The Missing Hybridity: ‘Envisioning’ Ukrainian Literary Space

    Directory of Open Access Journals (Sweden)

    Marco Puleri

    2015-05-01

    Full Text Available In this paper, the author focuses on the question concerning the complex positioning of the Russophone literary phenomenon in the Ukrainian post-Soviet literary canon. Analysing the conceptualization of the hybrid cultural elements in the post-Soviet cultural area, it is possible to observe the rise of a contrast between the cultural ‘exclusivist’ and ‘inclusivist’ attitudes in the Ukrainian literary debate. It is the product of the renewed social and political clash between the Ukrainian and Russian ‘national systems’. The ideologization of the ethnolinguistic factor in the Post-Soviet area gives birth to competing ideologies, which draw new ‘imagined borders’ in the Ukrainian literary space. It is the result of the polarization of the respective national historical narratives, misused by the current political discourses, to paralyse the dialogical perspectives in the process of cultural confrontation. Listening to the ‘voices’ of contemporary cultural actors, it will be possible to draw different images in order to envision the Ukrainian literary space.

    Full text: The issue of doses received by Chernobyl clean-up workers (liquidators) remains controversial both in terms of dose values (individual and collective) and reliability of available data. This deficiency became particularly evident during preparation of the Ukrainian contribution to the UNSCEAR report. Analysis showed that available official dose records (ODR) are neither representative nor unbiased and, therefore, cannot be used to indicate the impact of Chernobyl exposure on this cohort (∼230,000 individuals). Recent developments in the area of dosimetry for liquidators contributed to better understanding of this problem and added information regarding individual, group averaged, and collective doses to Ukrainian liquidators. It was established that majority (∼95%) of existing ODR are related to one particular category of clean-up workers military liquidators. All other categories of Ukrainian liquidators either do not have recorded doses or their doses are not presented in the Chernobyl State Registry of Ukraine (SRU). The main sets of new doses were derived from reassessment of about 8,600 ODRs performed within Ukrainian-American Chernobyl Ocular Study (UACOS) and results of independent dose reconstructions using a time-and-motion method called Realistic Analytical Dose Reconstruction with Uncertainty Estimation (RADRUE) for about 1,000 subjects in the Ukrainian-American study of leukemia and related disorders among cleanup workers from Ukraine. A third source of independent dose assessments is the set of individual doses obtained using EPR spectroscopy of tooth enamel; such estimates have been performed for about 800 Ukrainian liquidators. Analysis of dosimetric information related to military liquidators, who comprise about the 48% of Ukrainian liquidators, showed that as a rule ODRs for persons in this category systematically overestimate actual doses. Quantification of this overestimation gives a clue to retrospective adjustment of doses, at

The peculiarity of Ukrainian-Canadian cooperation due to the presence of 1.2 million Ukrainian diaspora, representing a non-economic pressure groups actively involved in the formation of the Ukrainian-Canadian relations. Canada today is our main partner and state support in the international arena. This is evidenced by the active position of Canada on the international stage in the Ukrainian crisis. After the illegal annexation of Crimea by Russia and the conflict in Donbas Canada has consistently supported Ukraine within the framework of international organizations (UN, OSCE, NATO, G7 and at the bilateral level. In addition, Canada has implemented economic and political sanctions against a number of Russian individuals and companies as well as representatives of the so-called «DNR» and «LNR» and separatist leaders. Relations with Canada is a promising destination for foreign policy strategy of Ukraine. Canada supports our country and contribute to its development, and helps to overcome the Ukrainian crisis. The question of Ukraine in Canada is always on the agenda, and, given the recent elections, we can say that Canada’s position on the international scene will always be on the user ID Ukraine and Canada support will only increase.

    2007-01-01

    Full Text Available Grammatical works of Juraj Križanić which were written in Russia, are observed from the viewpoint of their connection with the Ukrainian philology of the 17th century. Concrete examples show significant knowledge that this Croatian scientist had of the contemporary East-Slavic lexicographic and grammatical tradition. The challenge to create a grammatical vision of «the Slavic language» came to Križanić from the work of Meletija Smotry'ckyj, an eminent representative of Ukrainian philology. However, the Croatian author used the Ukrainian folk language to a great extent, which, unfortunately, hasn’t been recognized enough in the past extensive Križanićology. His connections to the Ukraine have traditionally been identified with the ones with Russia, and that is the consequence of a kind of inertia in distinguishing the Ukrainian from the Russian element on the East-Slavic territory. This work uses concrete examples to show the presence of various forms of the Ukrainian language culture in the works of the Croatian author. These works make Križanić the founder of the Croatian Ukrainian school. Through Križanić’s work Croatian philology enters the Ukrainian baroque linguistic culture.

    Full Text Available In this article the author studies the elimination of the national element in the Ukrainian cinema of the 1960s and 1970s. The author explores the role and place of national-patriotic issues in Ukrainian cinematography, shows the ideological enslavement of filmmakers, studies the conditions of creative self-realization in the Ukrainian SSR, and analyses the influence of social and political factors on the cultural sphere of Ukrainian people in the outlined period. The representatives of Ukrainian cinema has always tried to popularize national features of their own people, but in the specified period, for censorship reasons, Ukrainian cinema began to be prohibited. The main reason is the struggle with the so-called “Ukrainian bourgeois nationalism”. For such an accusation it was enough to voice any film in Ukrainian and to fill its content with Ukrainian subjects. The characteristic features of Ukrainian cinematography of the 1960s – the early 1970s are as follows: subordination to the Soviet centralized command-administrative system, total control of the CPSU – CPU, russification, denationalization, persecution of all Ukrainian values under the pretext of forming a united Soviet nation.

    Directory of Open Access Journals (Sweden)

    Taras Koznarsky

    2017-09-01

    Full Text Available At the end of the eighteenth century through the first decades of nineteenth century, as the last vestiges of Ukrainian autonomy were abolished, Ukrainian elites and intelligentsia embarked on a diverse range of projects (addressing geography, history, ethnography, travel writing, journalism, and literature aimed at privileging and promoting their cultural capital within the Russian imperial field of cultural production. The Ukrainian language and its origins, nature, and status came to the fore in these projects as Ukrainian literati carefully gauged their messages for both Ukrainian and metropolitan audiences in order to engage playfully and polemically with imperial perceptions of Ukraine and to further the cause of the Ukrainian language as a distinctive linguistic system, cultural legacy, and literary medium. These often cautious and purposefully ambiguous characterizations, classifications, and applications prepared the ground for the romantic generation of writers who dramatically expanded the stylistic and generic range of Ukrainian in their literary works and translations, and forcefully argued for the language’s autonomy, dignity, and expressive potential. While early romantic Ukrainian writings were seen as colourful linguistic and ethnographic regional variants useful for the development of Russian imperial and national culture, the growth of Ukrainian literature alarmed both Russian critics and administrators, who began to see in these developments not only unproductive and anachronistic vexations, but also a culturally and ideologically subversive agenda that had to be discouraged. By surveying and examining diverse classifications and discussions of the Ukrainian language by Ukrainian and Russian literati, the article questions the limits of so-called “Ukrainophilia” in Russian imperial culture of the early nineteenth century.

    Full Text Available This writing is devoted to the brief review of Immanuel Kant’s philosophy studies and receptions of his philosophical concepts within the Ukrainian philosophy of Soviet period. Such attempt is actually pertinent because nowadays we definitely need to reconsider the soviet philosophical heritage for better understanding the real value of any philosophical conclusions and worldview-concerning statements which were made in the times of soviet ideology hegemony. Additionally, mentioned reconsidering is presently urgent because Ukrainian intellectual culture is now looking for its identity and is trying to identify the stillremaining ideological totalitarian elements which spoil the originality and objectiveness of its products. The present review attempts to identify which totalitarian intentions and prejudices were used to interpret and evaluate the Immanuel Kant’s heritage in the texts written by several selected Ukrainian philosophers of the Soviet period. Nevertheless, it’s obvious that absolutely impossible to avoid talking about Georg Wilhelm Friedrich Hegel’s philosophical position interpretation by the same authors. Kant’s and Hegel’s soviet-Ukrainian interpretations were often connected, because there was a general trend of soviet Marxist history of philosophy to interpret Kant as the “worse” version of Hegel. To fulfill the general image of Kant’s philosophy interpretation in Ukrainian philosophy and its future perspectives, this paper also delivers some common information about the whole historical path of Kant’s interpretations and receptions

The main element is an aim. The aim is an ideal image of the expecting result which is regarded as a guide for the educational activity of a certain ethnic community. The content of the notion of educational ideal is the imagery about the most important qualities of a personality, their manners, culture of relationship in the society, behavior. Ukrainian mentality is practicality, rationality, generosity, intellect in general. It is fully reflected in the pedagogical aim. At the same time mental means spiritual. That is something in thoughts and intents of a person. It is important to emphasize that Ukrainian ethos was formed on the basis of several groups, not only having formed a nation, but also having synthesized the temperament, traditions and customs, clothes and everyday life, culture in general. Hutsul, Boyko, Lemko (121 ethnic groups all together differ by the uniqueness of the appearance. At the same time their internal essence, that is educational ideal, world view, ethic morals, are unchangeable. Educational ideal is historically determined. Esthetic strategies, formation of creativity, development of the abilities by the means of folk crafts and trades, upbringing of a host pierce through the educational ideal of nowadays Ukrainians. The people aim to bring up their children as true citizens: good kids mean quiet old age, while with evil children old age becomes a hell. Thus, the educational ideal of the Ukrainians should be considered as a basis for modern educational technologies projection.

    Full Text Available As fighting between Russian backed rebels and government forces is taking place in eastern Ukraine, it is all the more apparent the existing political divide that exists in the country. The complex history of being subjugated by surrounding countries and major resettlements of Ukrainians is testing the country in a major way. Historically, emphasis on understanding the Soviet Union was focused on the Soviet perspective — the Soviet narratives, and most recently on reemerging Russia. As a result, little attention is placed on Ukraine’s history. In order to understand the Ukrainian identity, it’s necessary to know the narratives that encompass Ukraine’s history. As freedom and liberty exemplifies American identity and ideology, the history of Ukraine also contains a system of stories that support Ukrainian culture. This paper, the first chapter of my dissertation, details the sources I’ve used to develop my methodology for understanding and analyzing narratives. As I began my research I soon realized the complexity of narratives leading me to explore the elements contained in narratives such as story, plot, character, archetypes, and the Hero’s Journey or Monomyth. I will explain how I understand the meaning of narrative and master narrative, supported by relevant sources, and conclude with the methodology I will use for analysis of the master narratives that envelope the major historical events of Ukraine

    Full Text Available The Ukrainian crisis has been a test for the alignment of Romania and Bulgaria with the EU on the background of the Union’s new foreign policy instruments as redesigned by the Lisbon Treaty. This paper aims to present the positions of Bulgaria and Romania towards the events of 2013-2015 in Ukraine. Our research target is to identify the driving forces that shaped these positions, to analyse and describe the main foreign policy goals and actions of Bucharest and Sofia regarding the Russian-Ukrainian conflict, and to compare the attitude of these two countries toward the Ukrainian crisis. The paper analyses first the Romanian and the Bulgarian perspectives on the dramatic events in Ukraine in the first half of 2014. The positions of the two countries are further placed in the wider international context of the Ukrainian crisis – the UN resolutions, the EU sanctions against Russia, NATO activities, and the security in the Black Sea region. In the third part Romania and Bulgaria are viewed as a “playground” for the competing narratives and propaganda in regards to the Russian-Ukrainian conflict. We also examine the economic impact of the crisis on the two Balkan countries, as well as the efforts of both Bucharest and Sofia to protect their respective minorities in Ukraine. In conclusion, we summarize the results of our research and explain how the Ukrainian crisis has reshaped the foreign policy debates in Romania and Bulgaria.

    Full Text Available For a long period of time from 1991 to 2016, the socio-economic development of Ukrainian regions was characterized by enhanced differentiation and persistent inequality. Permanent preservation of the gap between the maximum and minimum values of indicators of socio-economic development of regions, in particular, the GRP per capita (8.8 times in 2014; disposable income of populace (10.3% in 2015; unemployment rate according to ILO methodology (in 2.8 times in January-September 2016, the volume of realized industrial products (38,9 times in January-September 2016 indicate the persistence of centre-periphery relations between regions in the economic space of the country. This situation reduces the overall efficiency of the economy, which is reflected by the decline of Ukraine’s position in the rankings of international organizations. According to the global competitiveness index in 2015, Ukraine has shifted from 76 to 79 place compared with 2014, according to the Index of Human Development, there was a slight increase from 83 to 81 place.

    Full Text Available Ukraine is a country of the Mid-Latitude ecotone—a transition zone between forest zone and forestless dry lands. Availability of water defines distribution of the country’s forests and decreases their productivity towards the south. Climate change generates a particular threat for Ukrainian forests and stability of agroforestry landscapes. This paper considers the impacts of expected climate change on vulnerability of Ukrainian forests using ensembles of global and regional climatic models (RCM based on Scenarios B1, A2, A1B of the Intergovernmental Panel for Climate Change, and a “dry and warm” scenario A1B+T−P (increasing temperature and decreasing precipitation. The spatially explicit assessment was provided by RCM for the WMO standard period (1961–1990, “recent” (1991–2010 and three future periods: 2011–2030, 2031–2050 and 2081–2100. Forest-climate model by Vorobjov and model of amplitude of flora’s tolerance to climate change by Didukh, as well as a number of specialized climatic indicators, were used in the assessment. Different approaches lead to rather consistent conclusions. Water stress is the major limitation factor of distribution and resilience of flatland Ukrainian forests. Within Scenario A1B, the area with unsuitable growth conditions for major forest forming species will substantially increase by end of the century occupying major part of Ukraine. Scenario A1B+T−P projects even a more dramatic decline of the country’s forests. It is expected that the boundary of conditions that are favorable for forests will shift to north and northwest, and forests of the xeric belt will be the most vulnerable. Consistent policies of adaptation and mitigation might reduce climate-induced risks for Ukrainian forests.

    Full Text Available Ukrainian economists, similarly to Ukrainian society, are in the middle of the process of turning from the East to the West. However, the visibility of their work remains low both in the East and the West. The analysis of their publication activity (using data from the Web of Science and eLibrary confirms these assumptions. It is argued that the first step in this eventual transition consists in building the space for economic debates at the national level. Active and healthy debates at the national level will increase chances of Ukrainian economists to be heard internationally.

    Rutter, N.W.

    The principles, theory and knowledge on the behaviour of glaciers indicate that only confined glacier flow is a major erosional agent. Unconfined, areally flowing ice sheets such as those present over the Canadian Shield during the Pleistocene Period modified the landscape very little. The potential for deep glacial erosion in future glaciations over the Canadian Shield area is low. Nuclear waste disposal sites, based only upon potential glacial erosion, should be located a few hundred meters below the surface in competent, fractureless crystalline shield bedrock, in relatively reliefless terrain, a few hundred kilometers away from the Paleozoic boundary.

    This technical report is a comprehensive evaluation of the proposal by the Ukrainian State Committee on Nuclear Power Utilization to create a central facility for radioactive waste (not spent fuel) processing. The central facility is intended to process liquid and solid radioactive wastes generated from all of the Ukrainian nuclear power plants and the waste generated as a result of Chernobyl 1, 2 and 3 decommissioning efforts. In addition, this report provides general information on the quantity and total activity of radioactive waste in the 30-km Zone and the Sarcophagus from the Chernobyl accident. Processing options are described that may ultimately be used in the long-term disposal of selected 30-km Zone and Sarcophagus wastes. A detailed report on the issues concerning the construction of a Ukrainian Central Radioactive Waste Processing Facility (CRWPF) from the Ukrainian Scientific Research and Design institute for Industrial Technology was obtained and incorporated into this report. This report outlines various processing options, their associated costs and construction schedules, which can be applied to solving the operating and decommissioning radioactive waste management problems in Ukraine. The costs and schedules are best estimates based upon the most current US industry practice and vendor information. This report focuses primarily on the handling and processing of what is defined in the US as low-level radioactive wastes

    2014-12-01

    Full Text Available The purpose. The article attempts to analyze the agrarian policy of the modern Ukrainian State in the context of its human factor. It demonstrates the effects of agrarian reforms on social sphere of Ukrainian countryside. Methodology. The author uses the following methods: dialectical – in the depiction of the controversial nature of agrarian reforms; retrospective – in determination of the main stages of agrarian transformations inUkraine; comparative – in revealing common and different features in the agrarian policy of theUSSR and modernUkraine.The scientific novelty is in the substantiation of the natural unity of economic and social policies in agriculture, the use of a variety of historical sources for this purpose. Conclusions. While conducting agrarian reform, started in the early 1990s, and continued up to the present time, only economic factors are taken into consideration. At the same time, human factor, and the interests of the peasantry, in particular, were ignored and not taken into account, despite the declarations and promises of politicians. Peasants were removed from the determination of objectives, directions and methods of the agrarian reform. They acted solely as an object and not the subject of the reform. In this sense, the methods for carrying out agrarian reforms in an independent and democraticUkraine do not differ much from the methods of the Bolshevik leadership. Thus, as it is shown in the article, the consequences of the agrarian reform can be equally dangerous for Ukrainian peasants. The peasants will lose their land forever and become laborers on the land inherited from previous generations. While carrying out a large-scale reform of the agrarian sector, it mustn’t be allowed for oligarchs to take countryside, land and agriculture into their hands. The regulations of sale and purchase of the land must be so that the Ukrainian peasant will remain the main contractor.

    2016-07-01

    Full Text Available Purpose. To analyse the practice of transliteration of the Ukrainian cultivar names and rendering foreign names by means of the Ukrainian language, as well as special aspects of cultivar names spelling in special literature. Results. Cultivar names as a special category require preservation of primary graphics or sound type in the other language. This can be achieved by direct inclusion of the original name to the Ukrainian text or by practical transcribing, but not by transliteration or translation. Otherwise, Ukrainian names should be transliterated for inclusion to the texts in Latin characters. Transcription/transliteration in both directions is performed from the source language, though, as practice shows, in some Ukrainian publications the Russian is wrongly used as an intermediary language. Some national scientific publications ignore the recommendations of the International Code of Nomenclature for Cultivated Plants that is not conducive to the success of scientific communication in the globalized world. Conclusions. The foreign names of plant varieties should be entered into the Ukrainian text keeping the original spelling or by means of practical transcription. The loan of foreign names is performed by transcribing directly from the source language; if the language doesn’t have the Latin alphabet, Latinized name transcription is acceptable. Recommendations of the International Code of Nomenclature for Cultivated Plants that concern graphic highlighting of the cultivar names in the text enclosing them in single quotation marks and writing each word of a cultivar name with a capital letter should necessarily be applied in the foreign-language publications and extended to the Ukrainian special literature, at least, in terms of the use of single quotation marks. Ukrainian names should be transliterated only in accordance with the regulations.

    Introduction: The Ukrainian state has an urgent necessity of rapid search for essentially new legal and organizational forms of the healthcare system, reform of the legal regulation of healthcare services provision. In the context of European integration, the advancement of the medical industry reform is closely related to consideration of international standards and norms of health care. The aim: To study the impact of international medical law on the Ukrainian health care legislation. Materials and methods: International and Ukrainian regulations and documents on health care were used in the research. System and structural, functional and legal comparative methods as well as systematization, analysis and synthesis were determinative in the research process. Review: Systematization of international documents on health care was made. The major problems in the Ukrainian health care legislation were determined in terms of their conformity with the international legislative norms. The expediency of the Medical Code adoption was grounded and its structure was defined. Conclusions: Most health care international acts are ratified by Ukraine and their provisions are implemented in the legislation. Simultaneously, there is a row of problems, which hinder the Ukrainian health care development and place obstacles in the way of European integration. To remove these obstacles, it is expedient to create a codified act - the Medical Code, which would systematize the provisions of the current medical laws and regulations and fill in the existing gaps in the legal regulation of health care.

    Full Text Available The article examines the history of the formation of Ukrainian nationalist parties "Svoboda" and "Praviy sektor". First, that they express a structured nationalism and Russophobia in Ukrainian political space. Secondly, in Russia it has become customary to identify one with another. The paper gives an overview of the basic civil identities in Ukraine, Eastern and Western. The author postulates that their conflict lies at the heart of the growing popularity of both nationalist parties. In addition, this process was provoked by the reunion of Crimea and Russia and by the civil war in the south-east of Ukraine. Before the Crimean crisis Ukrainian nationalism had primarily historical roots, and in many respects it was created by attitude of empire elites (the Russian and Soviet Empires to Ukrainians and their nation-state formations. After March-2014 it began to acquire a geopolitical indication exactly - Russia is perceived as an enemy. Two of the most famous actors of the Ukrainian nationalists and anarchists parties in modern Russia are "Svoboda" and "Praviy sektor". They have fundamentally different origins. "Svoboda" is a systematic force in Ukrainian politics for almost 20 years. Unlike it "Praviy sektor" was established like a party only in December 2013 within a framework of the Euromaidan. Due to the inability to compare the electoral history of both parties the author pays attention to the comparative analysis of their ideologies. Specific manifestations of extremism of "Svoboda" and "Praviy sektor" are not subjects of this research.

    Full Text Available The central argument of this paper is that radical and opposing interpretations of the Ukrainian conflict in politics and media should be studied as offspring of broader narratives. These narratives can be better understood by examining the national identity of Ukraine. Since Ukrainian national identity shows a high degree of diversity, it offers a rich source of arguments for any party wanting to give an interpretation of the present Ukrainian crisis. Narratives explaining the crisis often ignore this complex diversity or deliberately use elements from it to construct the ‘desired’ narrative.

    The present invention concerns lead shields for radiation shielding. Shield boxes are disposed so as to surround a pipeline through which radioactive liquids, mists or like other objects are passed. Flanges are formed to each of the end edges of the shield boxes and the shield boxes are connected to each other by the flanges. Upon installation, empty shield boxes not charged with lead particles and iron plate shields are secured at first at the periphery of the pipeline. Then, lead particles are charged into the shield boxes. This attains a state as if lead plate corresponding to the depth of the box is disposed. Accordingly, operations for installation, dismantling and restoration can be conducted in an empty state with reduced weight to facilitate the operations. (I.S.)

To perform an analysis the fish breeding, biological, productive, exterior indicators of Antoninsko-Zozulenetskiy carps of Ukrainian scaly and Ukrainian framed breeds, their genetic characteristics as well as to provide the methods of the creation of these carps as a selective achievement. Methodology. The works were carried out in accordance with conventional techniques in fish farming and breeding. Carp breeding was conducted by the method of mass continuously improving selection of fish the aim of which is that a complex of fish breeding and management activities create conditions contributing to the development of productive qualities in the selected carp, while selection and breeding activities form and reproduce the leading pedigree group of the stock. Findings. In the conditions of the development of fisheries industry, especially important are the problems of selection and breeding works aimed at improving the biological and economic features of fish farming objects by improving the existing and developing new breeds, inbreeding, zonal types, lines, etc., creating a progressive heterotic structure of breeds and forming highly productive pedigree stocks of fish breeding objects. The main object of commercial fish farming in Ukraine, as in many countries, is carp, so his selection is given much attention. The starting material for producing the Antoninsko-Zozulenetskiy Ukrainian scaly and Ukrainian framed breeds was carp population of Antoninskiy State fish hatchery (Khmelnytsky region, which was a cross between native carp with mirror Galician carp. The principal method of carp breeding was a massive, continuously improving selection with high intensity among younger age groups. An importance during the selection was given to the growth rate of the fish, their exterior and constitutional "strength." For the brood, individuals with the highest body weight, scaly cover of which corresponded to accepted standards, beautiful high

    Full Text Available The goal of the article is detection of interconnections between the common economic processes and formation of bank deposits by population. The article builds a correlation and regression model of complex assessment of interconnection between macro-economic factors, savings behaviour of population and level of deposits of population in banks for two hour horizons: short-term, which is characterised with deployment of crisis phenomena both in global economy and in Ukrainian economy and the medium-term one. The article characterises the most significant common macro-economic factors. In the result of the study the article establishes that Ukrainian population is oriented at short-term horizon when forming savings due to the uncertainty in future. In the medium-term prospective, savings of the population are formed basically under influence of macro-economic factors, while formation of deposits by Ukrainian population is mostly influenced by socio-psychological factors.

    Stepurko, Tetiana

    2012-07-01

    Full Text Available BACKGROUND: This exploratory research has been conducted in order to find out what reminiscences young Ukrainians preserve about their childhood nutrition. METHODS: 27 semi-structured interviews were conducted with respondents aged 17 - 34 yy. RESULTS: According to respondents’ answers, the parents tried to supply their children with a varied diet. There exists the cult of "traditional Ukrainian cuisine". Food is considered to be healthy if it is home-made. Such dishes have always been and are still considered to be the most popular: borsch, dumplings, stuffed cabbage rolls, potatoes, cereals, meat, and lard. Earlier and nowadays, parents maintain the principle of regular, non-separate nutrition. This implies that children should eat three to five times a day. Parents truly believe that children’s diet should consist of all kinds of food. The majority of respondents told that one of their parents’ greatest responsibilities was to serve at least one soup and one hot dish a day.DISCUSSION: Such popular traditional dishes like soup or cutlets are usually considered to be healthy and useful food, despite being rich in fat and salt. Moreover, the desire to feed children as much as might be a manifestation of the self-preservation instinct, because our society has experienced famine caused by wars, disasters, and the Holodomor tragedy.CONCLUSIONS: The research revealed that the traditional concept what healthy nutrition is, passes from one generation to another. Nevertheless, there is the tendency to reconsideration of "healthy food" in adulthood in favor of separate nutrition. These preliminary results of the exploratory research should be deepen to clarify what proper nutrition means for older and younger Ukrainian generations regarding regional, socio-demographic, and economic factors, which, in turn, will contribute to adapting the program of healthy eating promotion to the needs of Ukrainian people.

    In territory of Ukraine been found 9 explosive craters. Most researchers believe, that all of them were formed by the fall of celestial bodies on the Earth. However, were expressed an opinion on the endogenous (terrestrial) origin some of them. Ukrainian crystalline shield due to it geological stability for a long time (more than 1.5 billion years) has the highest density of large astroblemes on the Earth's surface. This shield extending from the northwest to the southeast of almost 1000 km along the right bank of the Dnieper River. Maximum of its width is 250 km. All impact craters on the territory of Ukraine are under a large (100-500 m) thickness of organic sedimentary deposits. So their research was carried out with using wells. The largest Ukrainian astrobleme is Manevitsk. It is located in the Volyn' region; has a diameter of 45 km; it originated, probably, around 65 million years ago. Ilyinets crater located in Vinnytsia region. It is the oldest astrobleme of Ukraine. It was formed about 430 million years ago in the fall of an asteroid with a mass of 40 million tons and a diameter of 230-300 meters. In the central part of the Ukrainian Shield is another unique geological structure: Boltysh crater. Its diameter is about 24 km. It originated 65,17 ± 0,64 million years ago when a meteorite falling on the ground. Sometimes find that it confirms the theory of multiple impacts as the cause of Paleogene extinction. Obolon' crater has 20 kilometers in diameter; it is located in Poltava region on the northeast slope of the Ukrainian shield. It is formed ˜169 million years ago. Ternivka crater located on the outskirts of Kryvyi Rig; its diameter is 11-12 km, and age is 280±10 million years. Bilylivka crater is the impact structures with a diameter of 6.2 km; was formed in the fall of a meteorite about 165 million years ago.

    Full Text Available This paper studies the determinants of the total factor productivity (TFP for Ukrainian firms in the manufacturing sector across macro-regions using recent micro-level datasets for 2013. Our empirical results show some degree of heterogeneity across Ukrainian macro-regions; in particular, the link between the total factor productivity, firm size, imports and the level of competition seems to be valid for all macro regions. However, the effects of private ownership status, capital intensity and exports seems to be region specific. In addition, we found no relationship between firm productivity and foreign ownership for any of the regions.

    Full Text Available The main prospects and risks of development of Ukrainian-Chinese trade and economic relations have been researched in the article. It has been grounded that there is a considerable need for attraction of external financing for Ukraine, and China is one of the potential partners for this purpose. The areas of interest of Ukraine in cooperation with China have been determined, in particular, the attraction of external investments that will allow the intensification of economic growth in the country, and will provide creation of new workplaces. The sphere of interests of China in Ukraine has been determined, namely, the possibility of attraction of Ukrainian technologies to Chinese market with the placement of production in the territory of China. It has been found out that it is considerable risk for Ukraine as in 5–7 years Chinese partners will seize Ukrainian technologies and the need in Ukrainian partners for them will disappear. Besides, there is a risk of irrational use of land resources that may lead to depletion and decline of its quality. In order to avoid negative consequences of economic cooperation with China Ukraine needs to develop strategy of the economic partnership providing satisfaction of national interests.

    The Ukrainian Carpathians are characterized by high air pollution caused by emissions from numerous industries. We have been monitoring the state of forests in this region since 1989. The highest levels of tree defoliation (>30%) are found close to industrial emission sources and in the upper mountain forests of the Ivano-Frankivsk and Chernivtsi regions. This is caused by a combination of strong anthropogenic influences (pollution, illegal uses, recreation) as well as poor site and climatic conditions. In the Ivano-Frankivsk region, Cd and Mo accumulate in forest soils; Cr, Mo and Zn soil concentrations are higher than their limit levels; and Pb concentrations exceed toxic levels close to industrial areas (10% of the region territory). Local background levels of heavy metals are greatly exceeded in snow close to industrial regions. Analysis of correlation matrices shows that the chemical elements Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, V and Zn occur at pollution levels in natural ecosystems in the Ukrainian Carpathians. Maximum concentrations of toxic elements occur in the oak forest zone; the most industrially developed area of the region. Toxic heavy metals in the Ukrainian Carpathians forests enter with precipitation and dustfall, then become fixed in soil and accumulate in leaves, needles of vascular plants and mosses. Concentrations of these metals decrease with altitude: highest in the oak forests, less in beech, and lowest in the spruce forest zones. However, some chemical elements have the highest concentrations in spruce forests; V in needles, As in snow, and Ba and Al in soils. - Local industrial emissions of heavy metal pollution and the condition of Ukrainian Carpathians forests are examined

    Strengthening of SSAC is a necessary condition for application of integrated safeguards. Ukrainian State System has been working since 1994 and passed several stages in its development: At the early stage it allowed us to conclude the first Safeguards Agreement; In 2003 SSAC covered also all nuclear material at locations outside facilities; In 2006 Additional Protocol (AP) entered into force. The significant contribution to strengthening of SSAC has been made by ISSAS mission carried out in Ukraine in 2007. The mission helped us to evaluate the State Safeguards System, provided us recommendations on improving of legislation, in particular to establish the system of personnel training. Cooperation between the IAEA and Ukrainian SSAC is carried out in following directions. Annual meeting of Safeguards Implementation Review Group takes place in Kiev. Participants discuss current tasks or problem issues of Safeguards implementation and work out Action Plan in order to resolve a problem or find a way for improving situation. Ukrainian State inspectors organize and take part in each IAEA inspection and complementary access. Ukraine has got considerable experience in the AP implementation, to a certain extent determined by peculiarities of Ukraine as a former part of a nuclear weapon state. For 5 years we have accumulated a significant amount of AP information and it became a problem to keep track of it. Due to Protocol Reporter software has limited possibilities there was a need to develop additional software for AP information management. The transmission of encrypted data on nuclear materials from surveillance systems installed at all NPPs directly to the IAEA Headquarters has started recently. Since September 2010 the IAEA plans to use these data for drawing conclusion of safeguards implementation that will allow to reduce the number of IAEA inspections to the Ukrainian NPPs. While implementing the AP we got a question about correspondence of efforts spent for

    Full Text Available The article deals with the problems of historiosophy, whose subject matter is human and social world view, its historical, religious, intellectual, ethical and aesthetical aspects. Hence historiographical interpretation of the concept of morality, ethical criteria, and distinction between morality and ethics. These issues are viewed from the perspective of spiritual morality. Assuming that spiritual values affect deepest human feelings, our life principles and attitude to God in a special way , morality may be defined as the system of interrelationship among people, which comprises spiritual values, life experience, ways and traditions. Such an approach helps to comprehend the degree to which spiritual values influence morality and religious views of the Ukrainian people, the specific way in which the system of ethical values was built in the time of the Messianic Christianity. The formation of world view, morality and ethics is closely related to the issues of faith and social life, as well as to the development of the national philosophy and theology, both in the past and nowadays; these processes and phenomena are a significant factor in the way Ukrainians perceive themselves, the world around them and the Universe.

    Full Text Available Background: The author of the article attempts to initiate a scholarly discourse on mycological vocabulary, especially the names of macrofungi (macromycetes, a valid issue which still has not been fully described. He proposes a contrastive analysis (Ukrainian-Polish of the discourse on the contemporary mycological vocabulary functioning in various texts: scientific, popular science, literature, as well as folklore. Purpose: The purpose of the article was to characterize selected sources of mycological vocabulary and present Ukrainian and Polish research. Furthermore, the author wanted to propose a preliminary semantic analysis of selected Ukrainian and Polish names of inedible and poisonous mushrooms (particularly those that can be found in both countries. Results: Myconims are direct or indirect references to the specific characteristics of fungi. The article contains a table containing 92 official names of the most common inedible and poisonous fungi in Poland and Ukraine (Latin, Ukrainian, and Polish names. This list can be expanded with further hundreds of names, since, as mycologists and mushroom researchers claim, there is approx. 4 thousand species of macrofungi on the territory of Ukraine and Poland. In the article the official names of Ukrainian and Polish inedible and poisonous mushrooms were classified into eight groups. Elements most frequently co-creating the collected myconims (comparable for both languages are lexemes indicating: the color of the cap or the fruiting body, the place and manner of its occurrence, the overall appearance of the fruiting body. Significant, especially for the Ukrainian names of mushrooms, is the presence of Latinisms, which is characteristic of Ukrainian specialized terminology, such as the medical one (eg. cirrhosis hepatis, цироз печінки; glomerulonephritis, гломерулонефрит; appendicitis acuta, апендицит etc.. Most myconims, both Polish and Ukrainian, are two

    Previous attempts to crystallize mammalian γS-crystallin were unsuccessful. Native L16 chicken γS crystallized avidly while the Q16 mutant did not. The X-ray structure for chicken γS at 2.3 Å resolution shows the canonical structure of the superfamily plus a well-ordered N arm aligned with a β sheet of a neighboring N domain. L16 is also in a lattice contact, partially shielded from solvent. Unexpectedly, the major lattice contact matches a conserved interface (QR) in the multimeric β-crystallins. QR shows little conservation of residue contacts, except for one between symmetry-related tyrosines, but molecular dipoles for the proteins with QR show striking similarities while other γ-crystallins differ. In γS, QR has few hydrophobic contacts and features a thin layer of tightly bound water. The free energy of QR is slightly repulsive and analytical ultracentrifugation confirms no dimerization in solution. The lattice contacts suggest how γ-crystallins allow close packing without aggregation in the crowded environment of the lens. Published by Elsevier Ltd.

    Full Text Available The article proposes an investment model for the development of Ukrainian enterprises in the agrarian sector, which is one of the «locomotives» of the domestic economy. However, only by creating high value-added can be expected sustainable economic development both as an economic entity and as a whole economy of country. A long-term partnership with the advanced economies of the world is another key prerequisite for sustainable economic development. The article explores a potential Norwegian market in the context of the consumption of agriproducts as fodder for aquaculture, as well as Ukrainian agrarian market. Ukraine’s competitive advantages in the market for food ingredients for fish in Northern Europe have been formulated. The results of the study point to the high potential of soybean protein concentrate (SPC for the Norwegian market and, in turn, the great prospects for Ukraine in this market as a leader in the European soya growing. Measures that will facilitate the establishment of strong economic ties between Ukrainian agrarian enterprises and the markets of the developed countries have been determined. An investment model for the intensive development of Ukrainian enterprises in the agrarian sphere has been formed.

    Full Text Available Ukrainian nationalism appears in the middle of the XIX century. Russian conservatives do not perceive it as a serious threat. Attitude to this problem has done serious evolution - from ridicule of cranky small group of provincial intellectuals to recognize the imminent prospects of territorial division and the breakdown of historical unity of the Russian people. Editor of "Moscow News", a well-known publicist, M.N. Katkov was the main critic of "ukraynofilstvo" in the second half of the XIX century. Otherwise, but also critical as a whole, perceived this movement M.F. De Pulet, I.S. Aksakov and V.J. Shulgin (founder of newspaper "Kievlyanin". A major criticism of Ukrainian nationalism was the conservative writers of the period: P.A. Kulakovskiy, L.A. Tikhomirov, M.O. Menshikov, V.M. Purishkevich, D.V. Skrynchenko and D.D. Muretov. In particular positions stood nationalist T.V. Lokot', considered people of Great Russia, Russia Minor and Belorussia as the Russian ethnic groups, not united into a political nation. The most consistent and staunch fighters against the "Ukrainians" was Kiev residents A.I. Savenko and V.V. Shulgin. Despite the rather harsh assessment of the emerging "Ukrainians", representatives of the conservative camp did not allow themselves pejorative judgments at the inhabitants of Russia Minor. Among the Russian conservatives were quite a few people who both believed to be children of the Great Russia and Russia Minor, but they perceived «Ukrainian idea» as a chimera. It was imposed to people by anti-Russian part of the local intelligentsia. Russian conservatives have not seen in the emergence of "Ukrainians" any historical validity. They interpreted this as a political project, aimed at the division of a single nation, and the state territory, favorable to geopolitical rivals of Russia.

  6. Missed Opportunities: Early Attempts to Obtain Bukovynian Orthodox Clergy for the Ukrainian Pioneers of Alberta

    Full Text Available Immigration from the Austro-Hungarian crown land of Bukovyna to the Canadian West was initiated in 1897-98, continuing thereafter until the outbreak of the First World War. Comprised mostly of ethnic Ukrainians, but including a small number of Romanians and families of mixed marriages, the peasant farmers from Bukovyna took out homesteads alongside the fledgling colony established northeast of Edmonton a few years earlier by Ukrainians from Galicia. An immediate concern of the settlers was the lack of any priests to serve their pastoral needs and to provide leadership for the communities that they were struggling to establish in challenging circumstances in the New World. Although itinerant priests dispatched by the Russian Orthodox mission based in San Francisco began visiting the Ukrainian settlers in Alberta beginning in July 1897 at the request of Russophiles among the first Galician homesteaders, the new arrivals from Bukovyna found them to be less than satisfactory because of linguistic and cultural differences. Almost immediately, the Bukovynians began appealing to the Orthodox Church in Bukovyna for clergy who could speak the Bukovynian Ukrainian dialect and “Wallachian,” so that they would not be dependent on priests from the Russian Mission. Despite numerous requests sent to the Metropolitanate of Bukovyna over the course of the next decade and a half—not only from Alberta, but also from other Bukovynian colonies in Canada—no Ukrainian clergy were ever assigned by church officials in Chernivtsi to serve the Orthodox faithful overseas. Drawing on archival sources, press reports and secondary sources, this article reconstructs these efforts by the pioneer era Ukrainian settlers from Bukovyna to obtain Orthodox clergy from their native land, at the same time suggesting reasons for their failure.

    Full Text Available The article is devoted to the problems of the efficiency increasing of the air transportation. The difficulties of increasing the efficiency of transportation by air in Ukrainian SSR in 1960-1980 were researched, factors that adversely affected the organization of the transport sector were determined and depicted. The article analyzes what caused such difficulties and it was found out that the causes of these difficulties are connected with the organizational problems of air transport of Ukrainian SSR, which negatively affected the operation of the industry. The central aim of the research is to focus on the main problems of air transport of Ukrainian SSR. So, we should say that the transport operation of those years was distributed too unevenly and was dependent on the population density of the territory of the republic. Purpose of the article is to determine, compile and analyze the factors that negatively affected the organization of air transportation of the Ukrainian republic and reduced the efficiency of its operation. Results of the research shows technical, organization and economical deficiency of air transport of Ukrainian SSR which caused the ineffectiveness of this type of transport and determines the nature of such difficulties. Statement of the problem. During the specified period (1960–1980 the air transport had undergone rapid development. Many new airlines were opened, airports were being built and reconstructed, the terms of exploiting of turbojet aircrafts were increased, the speed of planes was increasing. All these facts ensured safe and reliable air connection of all district centers, connected Ukraine with the other Soviet republics and foreign countries by air corridors. Ukrainian Department of Civil Aviation became the biggest regional Department of the Ministry of Civil Aviation of the USSR. But, at the same time the intensity of the increase of cargo and passenger transportation since 1970s led to accumulation of

    Full Text Available In the article the legal mechanisms of strengthening altruism in Ukrainian society are analysed. Altruism constantly develops, acquires new forms under act of public relations. In modern Ukrainian society altruism must take the special place in institutionalization of human dignity and rights and freedoms of man, become the norm of social activity. In the article there is a necessity of perfection of normatively­legal base on the basis of principle of altruism, harmonization of relations between the state and civil society in the field of the altruism directed practices. Sharp social contradictions, estrangement of man, can be overcame only through claim of initial social values on principles of idea of dignity and human rights. There must be valuable partnership of the state and eleemosynary organizations in democratic society, creating favourable terms for opening public potential and directing of altruism activity of population. The special attention must be spared to providing of rights for invalids and defencing of them from discrimination.

    Full Text Available The development and implementation of any policy require the creation of preconditions for ensuring the independence of such a policy. In order to provide such preconditions, it is necessary to build up an institutional framework and regulate the key principles of development and implementation of an appropriate policy. the macroprudential policy is no exception, either. The macroprudential policy is a new policy area, which aims to identify, analyze and counter risks to the financial system as a whole, as opposed to traditional microprudential regulation and supervision, whose focus is exclusively on the risks of individual institutions. In many countries, the processes of appropriate legislation and building an institutional framework are ongoing. The article is focused on a comparative analysis of the Serbian and the Ukrainian approaches to macroprudential policymaking. The differences and the similarities between the Ukrainian and the Serbian macroprudential policymaking models are generalized.

    Full Text Available The article is devoted to the activities of the Ukrainian think tanks in the context of studying “the Center of it. A. Razumkov” activity, which is supposed to be the leading Ukrainian think tank. The authors examined in detail the mechanisms and principles of the center’s work, analyzed the activity of key experts including A. Gritsenko, G. Sherr, P. Rozenko, A. Melnyk, I. Zhdanov, V. Chaly, Yu. Mostovaya, N. Martynenko, A. Rachok and sources of funding. The researchers highlighted a number of issues of the Ukrainian system of analytical centers, including the closed system of decision making at the state and local authorities level, the lack of demand for the services of independent analytical structures by public authorities, weak financial, material and technical base, the absence of staff training, poor communication between the centers, insufficient use of the Internet, software and hardware, information-analytical systems, and so on. While analyzing their activities the author comes to the conclusion that they have mostly been funded by various agencies (including foreign ones and used in opposition between the local political and financial elites. As a result their expert assessments and analytics very often did not reflect the real situation. Within the civil war in Ukraine in 2013-2014’s these think tanks finally turned into an instrument of information and psychological war, being discredited by their actual support to the actors which had staged a coup and started a struggle against their own nation.

    2018-02-01

    The shield design in particle accelerators and other high energy facilities are mainly connected to the high-energy neutrons. The deep penetration of neutrons through massive shield has become a very serious problem. For shielding to be efficient, most of these neutrons should be confined to the shielding volume. If the interior space will become limited, the sufficient thickness of multilayer shield must be used. Concrete and iron are widely used as a multilayer shield material. Two layers shield material was selected to guarantee radiation safety outside of the shield against neutrons generated in the interaction of the different proton energies. One of them was one meter of concrete, the other was iron-contained material (FeB, Fe2B and stainless-steel) to be determined shield thicknesses. FLUKA Monte Carlo code was used for shield design geometry and required neutron dose distributions. The resulting two layered shields are shown better performance than single used concrete, thus the shield design could leave more space in the interior shielded areas.

    In the former USSR, unlike most countries, radioactive waste management activities including waste disposal needed no license. But after the USSR breakdown the Ukrainian Parliament -- Verkhovna Rada -- invoked the revised Law on Business activities. According to Article 4 of the Law, in order to treat or to dispose radioactive waste every enterprise has to get a special permission or license. In compliance with the Law, the Cabinet of Ministers by its Ordinance of January 13, 1993, authorized the Ukrainian State Committee for Nuclear and Radiation Safety (UkrSCNRS) to issue special permissions or licenses for waste treatment and disposal. And that requirement was valid not only for future activities but also for existing facilities in operation. Taking into account the undergoing legislative process, SCNRS began to develop its licensing process without waiting for the special nuclear laws to be passed. On the basis of the legislation already in effect, first of all the Law on Enterprises (full responsibility of enterprises for their activities) and Law on Business activities (requirement to have a license for special types of activities), the newly formed national regulatory body had to identify all the enterprises that needed to be licensed, to establish relevant procedures, to develop related regulatory documents, to implement these procedures and documents at operating enterprises, and for each case to make a decision concerning feasibility of issuing a license, period of validity and license conditions

The strategy proved to be inefficient due to the fact that Ukraine did not hold the required leverage for this kind of strategy and the consequence was observed in the current instability from the Ukrainian state. At the same time, these events are the effect of an announced Russia’s change of strategy. Crimea’s annexation and the violent acts from Donbas put under question mark the security and stability of the entire European continent. The EU’s legitimacy vis-à-vis its global power status given its inability to act regionally in an efficient manner. Additionally, Russia was perceived as a revisionist state that did not follow the international rules anymore. To a certain point the events from Ukraine were viewed as a new type of war in terms of tactics. The present article aims to analyse the degree to which the events from Ukraine were predictable. The main research question of the study revolves around the following: Taking into account Russia’s perceptions over itself, Ukraine and the EU, was the Ukrainian crisis a predictable event? Regarding the methodology, the article will concentrate on document analysis (primary and secondary sources, in order to emphasize the correlation between the different/similar meanings that are displayed within the strategic, official documents and the discourse level, to see if there were some hints regarding the events that were to be developed.

    The basis of shielding practice against external irradiation is shown in a simple way. For most sources of radiation (point sources) occurring in shielding practice, the basic data are given, mainly in the form of tables, which are required to solve the shielding problems. The application of these data is explained and discussed using practical examples. Thickness of shielding panes of glove boxes for α and β radiation; shielding of sealed γ-radiography sources; shielding of a Co-60 radiation source, and of the manipulator panels for hot cells; damping factors for γ radiation and neutrons; shielding of fast and thermal neutrons, and of bremsstrahlung (X-ray tubes, Kr-85 pressure gas cylinders, 42 MeV betatrons, 20 MeV linacs); two-fold shielding (lead glass windows for hot cells, 14 MeV neutron generators); shielding against scattered radiation.

    A fixed shielding member made of a radiation shielding material is constituted in perpendicular to an opening formed on radiation shielding walls. The fixed shielding member has one side opened and has other side, the upper portion and the lower portion disposed in close contact with the radiation shielding walls. Movable shielding members made of a radiation shielding material are each disposed openably on both side of the fixed shielding member. The movable shielding member has a shaft as a fulcrum on one side thereof for connecting it to the radiation shielding walls. The other side has a handle attached for opening/closing the movable shielding member. Upon access of an operator, when each one of the movable shielding members is opened/closed on every time, leakage of linear or scattered radiation can be prevented. Even when both of the movable shielding members are opened simultaneously, the fixed shielding member and the movable shielding members form labyrinth to prevent leakage of linear radioactivity.

    Full Text Available Athletic performance is a polygenic trait influenced by both environmental and genetic factors. Objective: to investigate individually and in combination the association of common gene polymorphisms with athlete status in Ukrainians. Methods: A total of 210 elite Ukrainian athletes (100 endurance-oriented and 110 power-orientated athletes and 326 controls were genotyped for ACE I/D, HIF1A Pro582Ser, NOS3 –786 T/C, PPARA intron 7 G/C, PPARG Pro12Ala and PPARGC1B Ala203Pro gene polymorphisms, most of which were previously reported to be associated with athlete status or related intermediate phenotypes in different populations. Results: Power-oriented athletes exhibited an increased frequency of the HIF1A Ser (16.1 vs. 9.420P = 0.034 and NOS3 T alleles (78.3 vs. 66.220P = 0.0019 in comparison with controls. Additionally, we found that the frequency of the PPARG Ala allele was significantly higher in power-oriented athletes compared with the endurance-oriented athletes (24.7 vs. 13.520P = 0.0076. Next, we determined the total genotype score (TGS, from the accumulated combination of the three polymorphisms, with a maximum value of 100 for the theoretically optimal polygenic score in athletes and controls. The mean TGS was significantly higher in power-oriented athletes (39.1 ± 2.3 vs. 32.6 ± 1.5; P = 0.0142 than in controls. Conclusions: We found that the HIF1A Ser, NOS3 T and PPARG Ala alleles were associated with power athlete status in Ukrainians.

    2012-07-01

    Full Text Available BACKGROUND: Healthy eating practices are among important public health goals worldwide. We aimed to investigate socio-economic determinants of the nutrition habits of Ukrainian families. METHODS: Data from the “UKRAINIAN LONGITUDINAL MONITORING SURVEY 2007” were analysed. Factor analysis produced variables characterising eating practices, which were re-coded in binary variables indicating low/high food consumption. The bivariate and multivariate analysis was conducted to identify associations between socio-economic state and eating modes. RESULTS: Three dimensions of nutrition practices were identified in the factor analysis: “standard diet” variable associated with quantities of most food products consumed, it actually shows how much food in general the household consumes, “fruit-and-vegetable diet” variable was associated with quantities of various fruits and vegetables included in the questionnaire, and “processed-(pre-packed-food diet” variable was created based on its associations with products like sausage. More “processed” food was consumed by members of households which were generally better-off (equipped with dvd-player, computer (laptop, garage, and Russian-speakers. More plant food was consumed by the households with attributes of rural living (equipped with bottled gas, central or individual system of heating, those who possessed a motorcycle or a truck. The owners of a plot adjacent to rural house or land used for gardening were eating more fruits and vegetables. A small group of well-off urban dwellers (like those possessing tumble-dryers, tend to eat more plant food; however, this group is not numerous. CONCLUSION: Plant food eating in Ukraine stays a factor of survival rather than healthy eating for those households which dwell in rural areas and have no means to choose foods they want. Those people who achieve better socio-economic status tend to increase processed food portion of their diets. Only a very

    Full Text Available In November 24-25 2011 Kyiv hosted International conference "Party system of Ukraine: evolution, tendencies and perspectives of development," organized by I. F. Kuras Institute of Political and Ethno-National Studies at the National Academy of Sciences of Ukraine. The conference assembled a number of scholars from Ukraine and abroad, who are engaged in studying political parties. This was probably the first conference in Ukraine of such level exclusively dedicated to analyzing political parties, their role and place in the political life of Ukraine. The conference was unique and very productive in terms of the level of discussion and geography of participation. It has proved that Ukrainian studies of political parties - partology - has already formed and is dynamically developing. One particular point sparking lively discussion was defining the essence of the notion "political party" and whether it could be rightfully applied to Ukrainian political associations. The article suggests the author's considerations on the essence of the problem, which, in our view, is a central methodological problem (or the Rosetta stone of the Ukrainian partology. it may be rightfully stated that the solution of the problem will influence all further development of the discipline.

    Chosen European foreign policy vector for Ukraine establishes its obligation to enforce the process of adaptation of the EU law regulations in the internal legal policy. The approximation of Ukrainian law to the European Union (EU) "acquis communautaire" is not only the instrument for deepening our economic cooperation with the European Union, but also the important measure to enhance further development of Ukraine in general. National legislation, which regulate advertising and promotion of medical devices (MD), is not an exception. Some key points on legal regulation of abovementioned sphere is a base of this study. Ukrainian legislation, European Union`s Law Acts, EU's member-states law, WHO Acts and Recommendations, European Medical Technology Industry Association (EUCOMED) Acts. Article is based on dialectical, comparative, analytic, synthetic and comprehensive research methods. In accordance with Ukrainian legislation, there is no special law that concerns advertising on MD in Ukraine, this sphere is regulated by general law that named ≪About advertisement≫, but it doesn't take into account even main characteristics of such a special object as medical devices (MD). Moreover, the law ≪About advertisement≫ contain discrepancies in terms that are used, these contradictions, in our opinion, must be eliminated by appropriate law reforms. The advertising and promotion of MD in EU is regulated by a combination of EU and national legislation of EU Member States, national advertising and promotion of MD are not harmonized with the EU MDD for now, resulting in a fragmented legal landscape that differs from one EU Member State to the other. Practice of adopting different codes and guides that regulate advertising, including advertising of MD, is widespread in EU and EU Member States and thus must be used in Ukraine with appropriate reformation of national law.

    Four different procedures were conducted to load amine functionalized multiwall carbon nanotube (NH 2 -MWCNT) onto poly (ethylene terephthalate) (PET) fabric surface to obtain a microwave shielding sample. Plasma treated fabric which was subsequently coated with NH 2 -MWCNT in the presence of acrylic acid was chosen as the best sample. Surface changes in the PET fabrics were investigated by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Wide-angle X-ray diffraction was used to study the crystalline structure of the PET fabric. The microwave shielding performance of the PET fabrics in term of reflection loss was determined using a network analyzer at X-band (8.2–12.4 GHz). The XPS results revealed that the carbon atomic percentage decreased while the oxygen atomic percentage increased when the fabric was plasma treated and coated with NH 2 -MWCNT. The SEM images showed that the NH 2 -MWCNTs were homogenously dispersed and individually separated in the surface of fabric. Moreover, the structural studies showed that the crystalline region of the fabrics was not affected by NH 2 -MWCNT and plasma treatment. The best microwave absorbing properties were obtained from the plasma treated fabric which was then coated with 10% NH 2 -MWCNT in the presence of acrylic acid. It showed a minimum reflection loss of ∼−18.2 dB about 11 GHz. Proper attachments of NH 2 -MWCNT on the PET fabric surface was explained in the suggested mechanism in which hydrogen bonding and amide linkage are responsible for the achievement of microwave shielding properties with high durability

    1986-01-01

    Purpose: In shielding plugs of an LMFBR type reactor, to restrain natural convection of heat in an annular space between a thermal shield layer and a shield shell, to prevent the lowering of heat-insulation performance, and to alleviate a thermal stress in a reactor container and the shield shell. Constitution: A ring-like leaf spring split in the direction of height is disposed in an annular space between a thermal shield layer and a shield shell. In consequence, the space is partitioned in the direction of height and, therefore, if axial temperature conditions and space width are the same and the space is low, the natural convection is hard to occur. Thus the rise of upper surface temperature of the shielding plugs can prevent the lowering of the heat insulation performance which will result in the increment of shielding plug cooling capacity, thereby improving reliability. In the meantime, since there is mounted an earthquake-resisting support, the thermal shield layer will move for a slight gap in case of an earthquake, being supported by the earthquake-resisting support, and the movement of the thermal shield layer is restricted, thereby maintaining integrity without increasing the stroke of the ring-like spring.

    Among all the possible problems arising in a connection with provision of NPP power units safe operation, the maintenance and repair at the Ukrainian NPPs possess an important place. System of maintenance and repair at the Ukrainian NPPs is presently still traditional one, based on the former USSR' document ''Rules of the NPPs Equipment Maintenance and Repair Arrangement'' (RD.53.025.002-088). For to provide technical systems reliability and safety in an accordance with ''General Provisions on NPP Safety'' (OPB-82) (presently OPB-95 is in underway in Ukraine) nuclear operators are implementing their maintenance and repair. These procedures are obligatory conditions for NPP operation during all the life term. To implement an equipment maintenance and repair there are appropriate divisions in NPP structure envisaged such as departments, laboratories, sections, shops, etc. composing an NPP maintenance and repair service. There are also another specific enterprises engaged in such activities. (author). 2 tabs, 4 diagrams

    Full Text Available This article is devoted to the revolutionary struggle of the Ukrainian people in order to build their own state. The exile stage of the liberation struggle has been investigated by the author. This stage happened after the defeat of the revolution. Its members, while in exile emigration, were trying to comprehend what happened, to rethink it, to assess achievements and to conceptualize the future of the Ukrainian liberation process. During the investigation, the materials of the Central State Archive of higher authorities and government of Ukraine, sources from private funds of М. Shapoval, M. Balash, М. Timchenko; the fund of Prague group of the Ukrainian Socialist Revolutionary Party; funds of the Committee on commemoration of M. Shapoval; Funds of Ukrainian Social Institute (Ukrainian Sociological Institute, Ukrainian Free University, Ukrainian Economic Academy, established by Ukrainian emigrants on the territory of First Czechoslovak Republic, have been used. The above-mentioned sources are mainly narrative. Due to their disorder and dispersion, they still are little known. Moreover, the factual weakness of the narrative is its personal attitude, documentary non-proven, and, hence, its possible uncertain nature. However, the author does not exclude the fact that small attention to the exciting content of the post-revolutionary exile epistolary is explained by the dual unacceptability of its content: the Soviet historiography was unable to study it because of its ideological censorship restrictions and prohibitions, and modern historiography does not want to focus on defamatory assessments and interpretations on the liberation struggle of 1917-1921, especially heard from emigrants. Thanks to some openness of the participants of the revolution, which were very sincere in their stories due to the pain of defeat and grief of their exile status, and although biased at the same time, we can get some knowledge about atypical verbal history, that

    Full Text Available During the 1950s the Academy of Sciences editions program faced substantial changes. On the background of the brisk development of the research in traditional and new scientific fields there was a quantity increase of the periodicals, especially journals. It was caused by the change in the dynamics of scientific research during this time period, appearance and development of new scientific fields and dynamic gain in the number of young scientists. The editions increase appeared in several directions: by organization of journals of institutions founded in the system of the Academy of Sciences with a view to develop new scientific fields (journals "Automatics", "Applied Mechanics"; by transformation of institutions’ periodicals existing as scholarly works and transactions (journals "Soviet Literature Studies", "Ukrainian Historical Journal"; by continuation of editions previously published in academic institutions (journals "Ukrainian Physical Journal", "Popular Art and Ethnography". New editions foundation and old editions transformation influenced several problems solution all at once. Ukrainian scientists’ researches results were published immediately, which had a substantial influence on the acknowledgement of their priority in certain scientific fields. Increased circulation of published journals made a provision for a wide spreading of information on new scientific achievements among the researchers and practical production workers, which was of vital importance in the context of progressive growth of manufacturing in the country

  3. Protein surface shielding agents in protein crystallization

    Hašek, J.

    2011-01-01

    The crystallization process can be controlled by protein surface shielding agents blocking undesirable competitive adhesion modes during non-equilibrium processes of deposition of protein molecules on the surface of growing crystalline blocks. The hypothesis is based on a number of experimental proofs from diffraction experiments and also retrieved from the Protein Data Bank. The molecules adhering temporarily on the surface of protein molecules change the propensity of protein molecules to deposit on the crystal surface in a definite position and orientation. The concepts of competitive adhesion modes and protein surface shielding agents acting on the surface of molecules in a non-equilibrium process of protein crystallization provide a useful platform for the control of crystallization. The desirable goal, i.e. a transient preference of a single dominating adhesion mode between protein molecules during crystallization, leads to uniform deposition of proteins in a crystal. This condition is the most important factor for diffraction quality and thus also for the accuracy of protein structure determination. The presented hypothesis is a generalization of the experimentally well proven behaviour of hydrophilic polymers on the surface of protein molecules of other compounds

It is impossible to imagine the development of a modern economy without economic UPS and downs, which disrupted the economic stability and the economic entities enter into a certain imbalance. Not exception-eating is the development of the crisis and companies of Ukraine. The origin and course of the crisis in Ukrainian companies requires a deep scientific study of modern economic theory and practice, as it can be considered a certain phenomenon, with significant features in comparison with other countries in crises companies. The manifestation of the crisis can be expressed in the decline in production, the deterioration of economic indicators, the financial insolvency of the company, have other symptoms that characterize its presence, as well as evaluate the various degrees of severity. Despite the fact that the Ukrainian company has led to a crisis, as it was heavy, and what the symptoms manifested, the main aim of the company in a state of crisis of uncertainty is the "survival" of the market and the continuation of further functioning. The issue of assessing the severity of the crisis and to identify measures to eliminate it in Ukrainian companies is extremely important and yet insufficiently developed. This is because, firstly, in economic science remains poorly understood the essence of the crisis, its species and assessment methodology taking into account the realities of the modern Ukrainian. Secondly, the emergence of the crisis in Ukraine – a frequent phenomenon, their course is quite difficult and time-consuming, but also has its own characteristics, depending on the formation of the Ukrainian political and economic systems, historically developed social and economic development of the country, the impact of external macroeconomic factors.

    Full Text Available The article deals with the church and religious life of Ukrainians in the context of national and political processes during the 1960s and 1970s. The author characterizes the anti-religious policy of the Soviet government, shows its directions, forms, and methods, studies the attitude of Ukraine’s title nation representatives to religious persecution and to manipulation of religious consciousness by the communist leadership, and highlights comprehensive atheistic activities and the elimination of the ways for reviving religiosity among people. The author reveals the essence, the process of creating and artificially enforcing the new Soviet ritualism in Ukrainians’ lives. This ritualism has become a convenient tool for popularizing communist ideology in the Ukrainian SSR, destroying historical memory and undermining the national identity of the Ukrainian people. The new Soviet ritualism was also a means for implementing the policy of denationalizing Ukrainians, beginning with the age-old religious oppression of Ukrainian customs, traditions, and rituals. The model of state-church policy of the Soviet power in the described period was based on the use of a variety of forms and methods of struggle against religion, including: a comprehensive control over clergy activities, destruction of religious sites and sacred objects, as well as administrative, moral, and political pressure on believers. Displacing religion, the Soviet totalitarian state destroyed not only native religious customs of the Ukrainian people, but also violated the principles of the centuries-old traditional culture and undermined the national fortitude of Ukrainians.

    Full Text Available The current phase of global economic development is characterized by technological breakthroughs. However, the implementation of innovation and technological break through requires adequate scientific and technical potential that calls for funding of science at the appropriate level, which is at least of 3% of GDP. In Ukraine, the funding level of research and development sphere is very low - about 0.23% in 2016. This chronic underfunding has transformed the science in Ukraine into the spending area, at a time when it should serve as the major source of economic growth. Currently, the State's government broaches a point of establishing adequate financial and organizational conditions in order to restore the Ukrainian science and cause its self-repayment and profitability. The universities are the major source of technology all around the world and in Ukraine in particular, and technology transfer is the main tool of the innovation process, which implies commercialization of commercially attractive researches. Given the fact that Ukraine has strong scientific and technological potential, the development of an effective system of university-based technology transfer and strengthening of interaction between scientific and production spheres are to become important factors for innovation-driven growth in the State. The corresponding organization departments of Ukrainian universities are just starting to form, particularly in the Taras Shevchenko National University of Kyiv. The prospect of successful development of the network of university- based technology transfer in Ukraine will determine the conditions of integration of Ukrainian science into global and Common European scholastic environment; the latter should be carried out through equitable scientific and technical cooperation.

    Full Text Available Didactic potential of upbringing pupils in educational institutions of the Diaspora by means of artistic word has been analyzed. The attention is paid to the function of art – Ukrainian literature, which promotes the formation of fully developed personality, their preparation for the conscious and active labour activity, and therefore upbringing is closely connected with life. It is cleared out that when plunging into the system of the artistic world, the pupil learns from the life of the main positive characters how to live in the society and to be useful, because textbooks and manuals on the native literature, readers in the Diaspora provide the basis for children to learn the behaviour of consciousness, and the latter, as it is known, depends on the construction of the world in themselves, that is called the worldview. It is proved that the powerful moral-educational and artistic-aesthetic potential of Ukrainian literature is being implemented in the books of Western Ukrainian Diaspora with the aim of ethnic and cultural enrichment of pupils and above all the formation of national consciousness of Ukrainian children, active choice of their values of national spirituality. It is established that the didactic potential of the upbringing of pupils by means of artistic word allows instilling love to the native language, to Ukraine, and thus it slows down the process of assimilation. On the basis of the study of the scientific-pedagogical heritage of emigration teachers-philologists, the theoretical approaches and practice of schoolchildren education by means of the word have been analyzed, the significance of their experience for the modern educational practice has been substantiated. The system of education of schoolchildren by means of the word, which has been developed over the years, is actual for the development of pedagogical science and practice.

    Full Text Available Thanks to the all pervasive globalisation trends previous state borders have become more permeable and subject to change. As borders disappear previously separated borderlands can unite and form a spatial unit where more increased economic interactions could integrate both sides to the global economy.The European continent is such a case which previously had been puctuated by strong state borders. Today the continent sees the physical and intellectual disappearance of borders. Regional integrations – like the European Union – spur this process and helps the integration of borderland inside and outside of the common market. The creation of a common market was a huge success and still a great deal of benefits are anticipated from the fulfillment. We are not taken by surprise when we see a massive increase in the number of border related studies and researchers. This field is very popular today. However the difference between Western and Eastern Europe is huge because eastern state borders are still strong or they link peripheral regions. There - under the communist times- border crossings were restricted and trade links were quite poor. No wonder that the tendencies of the past are still determining. This paper focuses on of one the most peripheral external borderland of the Schengen zone: the Hungarian-Ukrainian borderland. Expectations are running high and the disappearance of the border is a long-awaited hope. First I take into consideration the relevant economic theory in connection with more intense borderland dynamics. In the literature the trade theory, new economic geography and the traditional location theory approach this question. The approaches do not give coherent and clear-cut answers so I have to turn my attention to different empirical approaches. These show huge heterogeneity depending on the nature and character of the borderlands. In the mentioned case, settlement-level data are not fully available so I conduct a

    Electromagnetic interference (EMI) shielding materials are well known in the art in forms such as gaskets, caulking compounds, adhesives, coatings and the like for a variety of EMI shielding purposes. In the past, where high shielding performance is necessary, EMI shielding has tended to use silver particles or silver coated copper particles dispersed in a resin binder. More recently, aluminum core silver coated particles have been used to reduce costs while maintaining good electrical and physical properties. (author). 8 figs

    The Chernobyl Childhood Illness Program (CCIP) was a humanitarian assistance effort funded by the United States Congress. Its purpose was to assist the Ukrainian Government to identify and treat adolescents who developed mental and physical problems following their exposure as young children to Chernobyl radiation. Thirteen years after the Chernobyl nuclear plant accident in 1986, the CCIP examined 116,655 Ukrainian adolescents for thyroid diseases. Of these, 115,191 were also screened for depression, suicide ideation, and psychological problems. The adolescents lived in five of Ukraine's seven most Chernobyl radiation contaminated provinces. They were up to 6 years of age or in utero when exposed to nuclear fallout, or were born up to 45 months after Chernobyl. Ukrainian endocrinologist and ultrasonographers used physical examination and ultrasonography of the neck to evaluate the adolescents for thyroid tumors. The adolescents were then screened for depression by the Children's Depression Inventory (CDI). After this, Ukrainian psychologists conducted individual psychological interviews to corroborate the adolescents' CDI responses. Papillary thyroid carcinoma was diagnosed in eight adolescents, a high prevalence rate similar to that reported by other studies from the Soviet Union. Screening identified thyroid nodules in 1,967 adolescents (1.7%). Depression was diagnosed in 15,399 adolescents (13.2%), suicide ideation in 813 (5.3%), and attempted suicide in 354 (2.3%). Underlying components of the participants' depression were negative mood, interpersonal difficulties, negative self-esteem, ineffectiveness, and anhedonia. Depression was greater in females (77%). Those with thyroid and psychological problems were referred for treatment. The adolescents screened by CCIP represent the largest Ukrainian cohort exposed to Chernobyl radiation as children who were evaluated for both thyroid tumors and depression. The group had an increased prevalence of thyroid cancer

    To assess the prevalence of intimate partner violence (IPV) in a sample of Ukrainian mothers of schoolchildren, and to examine the relationship between IPV and family, parent, and child characteristics utilizing multilevel models. Mothers of children aged 9-16 (n = 278, 93.5% Ukrainians) answered the Revised Conflict Tactics Scale (CTS2) assessing IPV. We also examined the relationship between IPV and maternal age, education, employment and marital status, family income, and rural or urban residence. Eighty-one percent of women reported psychological violence and 58% reported physical assault. On average, women reported 66 instances of IPV during the last year. Multilevel modeling revealed that lower maternal education, unemployment, not living with the husband or partner, and urban residency were associated with higher IPV victimization. Younger age and family income were not significantly related to IPV. IPV was a significant social problem in the present sample of Ukrainian mothers of school age children. Future policy and violence prevention programming should focus on supporting academic and employment opportunities for women, particularly for those living in urban areas.

    About the Scythian Shields

    2017-10-01

    Full Text Available Shields played major role in the armament system of the Scythians. Made from organic materials, they are poorly traced on the materials of archaeological excavations. Besides, scaly surface of shields was often perceived in practice as the remnants of the scaly armor. E. V. Chernenko was able to discern the difference between shields’ scaly plates and armor scales. The top edge of the scales was bent inwards, and shield plates had a wire fixation. These observations let significantly increase the number of shields, found in the burial complexes of the Scythians. The comparison of archaeological materials and the images of Scythian warriors allow distinguishing the main forms of Scythian shields. All shields are divided into fencing shields and cover shields. The fencing shields include round wooden shields, reinforced with bronze sheet, and round moon-shaped shields with a notch at the top, with a metal scaly surface. They came to the Scythians under the Greek influence and are known in the monuments of the 4th century BC. Oval shields with scaly surface (back cover shields were used by the Scythian cavalry. They protected the rider in case of frontal attack, and moved back in case of maneuver or closein fighting. Scythian battle tactics were based on rapid approaching the enemy and throwing spears and further rapid withdrawal. Spears stuck in the shields of enemies, forcing them to drop the shields, uncover, and in this stage of the battle the archers attacked the disorganized ranks of the enemy. That was followed by the stage of close fight. Oval form of a wooden shield with leather covering was used by the Scythian infantry and spearmen. Rectangular shields, including wooden shields and the shields pleached from rods, represented a special category. The top of such shield was made of wood, and a pleached pad on leather basis was attached to it. This shield could be a reliable protection from arrows, but it could not protect against javelins

    A number of atomic-bomb survivors were affected by shielding provided by terrain features. These terrain features can be a small hill, affecting one or two houses, or a high mountain that shields large neighborhoods. In the survivor dosimetry system, terrain shielding can be described by a transmission factor (TF), which is the ratio between the dose with and without the terrain present. The terrain TF typically ranges between 0.1 and 1.0. After DS86 was implemented at RERF, the terrain shielding categories were examined and found to either have a bias or an excessive uncertainty that could readily be removed. In 1989, an improvement in the terrain model was implemented at RERF in the revised DS86 code, but the documentation was not published. It is now presented in this section. The solution to the terrain shielding in front of a house is described in this section. The problem of terrain shielding of survivors behind Hijiyama mountain at Hiroshima and Konpirasan mountain at Nagasaki has also been recognized, and a solution to this problem has been included in DS02.

    Full Text Available The article deals with the economic diagnostics of some important macroeconomic indicators of Ukraine that will reveal the nature and speed of the economic transformation. During the period of 2003–2007, the Ukrainian economy grew at an impressive pace. However, at present, the country is undergoing a period of serious trials, it needs to address structural problems that endanger long-term economic growth. The way out of the current situation should be the realization of the potential for growth of advanced sectors and increase of productivity across the national economy. Special attention should be paid to the transition from extractive institutions to inclusive ones. Key factors in accelerating the Ukrainian economy are more vigorous fight against corruption and investment attraction. A set of institutional variables is proposed, which allows for a more thorough assessment of the nature of economic transformation in Ukraine and detection of such deviations – transformation of the national economy occurs at different speeds. Along with the traditional shifts in the structure of GDP (the dominating share of services, there’s still insignificant statistical effect of such important institutional categories as the level of political globalization, the control of corruption, the level of property rights protection, the rule of law, and the level of social globalization.

    The data given concern uranium and thorium contents in the most important rock types of the Ukraina shield. The smallest quantities of uranium are characteristic for the vulcanic rocks of basic and ultrabasic rocks. Archean formations, whose source materials were mainly basic and ultrabasic vulcanites, are marked by this low uranium content. The highest uranium content is observed in the clastogenic rocks of low Proterozoic. The average uranium content is observed in silty argellite rocks represented by crystal slates and paragneissis. Rheomorphic and metasomatic granites and granosyenites of low and middle Proterozoic are also characterized by an increased content of uranium. The platform precipitation rocks of high Proterozoic possess a relatively low uranium content. Thorium concentrations with low thorium-uranium proportions in granites, syenites and granosyenites prove their enrichment in uranium

    As the system characteristics, the target in the spectrometer emits approximately 1012 neutrons/s. To efficiently shield the neutron, the shielding door designs are proposed for the LSDS system through a comparison of the direct shield and maze designs. Hence, to guarantee the radiation safety for the facility, the door design is a compulsory course of the development of the LSDS system. To improve the shielding rates, 250x250 covering structure was added as a subsidiary around the spectrometer. In this study, the evaluations of the suggested shielding designs were conducted using MCNP code. The suggested door design and covering structures can shield the neutron efficiently, thus all evaluations of all conditions are satisfied within the public dose limits. From the Monte Carlo code simulation, Resin(Indoor type) and Tungsten(Outdoor type) were selected as the shielding door materials. From a comparative evaluation of the door thickness, In and Out door thickness was selected 50 cm

    The features of genetic structure and level of diversity were investigated for G. lutea populations from Chornohora Ridge of Ukrainian Carpathians using RAPD- and ISSR-PCR. We have shown a high level of genetic diversity for investigated populations. The differences between populations account for 59-72% of the total genetic variation, whereas intrapopulation polymorphism makes up 28-41%. The relationships among genetic variability level and ecological-geographical conditions as well as biological features of the species were assumed to be possible. The obtained results indicate the genetic isolation of G. lutea Chornohora populations from Ukrainian Carpathians. Pozhyzhevska agropopulation was characterized by a high level of polymorphism that means the possibility to use artificial plantings of the investigated species for its conservation.

    Full Text Available The article defines key features of introduction of risk-management at the Ukrainian enterprises taking into consideration personal characteristics of managers and identifying the main risks that impact entrepreneurial activity. It has been proved that the essence of entrepreneurial activity is reduced to adequate perception of risk by the entrepreneur and to the ability to prevent its occurrence. The authors suggest their own approach to definition of the essence of entrepreneurial risk. In the article, risk management is considered as a system of enterprise management, providing for timely detection (proactive action and adequate response to the occurrence of risks in the entrepreneurial activity (protective action, the purpose of which is to ensure the seamless operation of the enterprise and its continuous development. The algorithm of implementation of risk-management at enterprise has been developed. The «Top-10 risks of 2017» has been analyzed and it has been concluded that for the Ukrainian enterprises the most significant for today are: changes in the legislation; raising the level of taxes, fees and costs of communal payments; unskilled personnel; loss of the consumer as result of actions of competitors; raider attacks; ATO.

    Full Text Available The article analyses the reaction of top officials, politicians and representatives of the expert community of the Eurasian Economic Union member countries on the aggravation of "Ukrainian crisis" in the context of plans and directions for further Eurasian integration. Today, in the scientific community is becoming a popular" dilemma of integration " as a systematic pattern that determines the development of relations between the integration associations. The dilemma of integration is a political phenomenon, a regular and predictable. Ukrainian crisis, which has become a litmus test of conflict of representations of the CIS countries on the extent and depth of their involvement in the processes of regional integration , most clearly outlined the presence of such dilemma within the CIS. In the current situation for Belarus and Kazakhstan as two , along with Russia , the main designers of the Eurasian field, the dilemma of integration takes a fundamentally different meaning and becomes a so-called "Dilemma of integrations", or contradiction between the desire of these countries to secure the most favorable conditions in its relations with Moscow and reluctance to fully bear the burden of the costs and constraints arising in relations with the EU due to the commitments of the EAEC. Based on the material of the official position of the representatives of Republic of Kazakhstan and the Republic of Belarus the author of the article explores the implications of the Ukrainian crisis in relations of Three: Moscow, Astana and Minsk.

    In the period of the Soviet Union Ukrainian Mechnikov Anti-Plaque Research Institute was one of the main bases of centralized training for laboratory diagnosis of especially dangerous infections. Not only specialists, but medical technicians were obligatory trained. In training programs special attention was paid to the safety regime in accurate work out of practical manipulations in investigational classical methods (cultivating technique, pipeting, animals' infection and dissection, etc.), protective clothes usage, anti-epidemic measures use at different accidents. This approach gave effective results not only in laboratories but also during field work (natural plaque foci investigations, etc.) and at emergencies. Recently in world practice to increase the level of biosafety technical equipment and devices are developed and used very intensively. During training maximal time is paid to their mastering. At such training biosafety practically depends on safe and reliable work of engineer-technical systems. At present in Ukrainian Anti-Plaque Institute with the support of Canadian Government Training Centre on biosafety and biodefense for specialists of Ukraine and FSU countries is being organized. Teaching programs will include complex study of hand manipulations and modern technical means knowledge. To our mind such initial training had to be available for all specialists of BSL 1-2 microbiological laboratories of any subordination. For this goal all kinds of programs will be developed. Such complex approach will promote to decrease biological risks in microbiological laboratories and prevent infectious agents import from working territories.(author)

    Full Text Available The study addresses the problem of the formation of customer loyalty in the market of high-tech products. It examines existing approaches to defining the determinants that influence the formation of loyalty in the consumer market. On the basis of generalization of existing approaches it is proposed to divide the determinants of such groups: behavioral, perceptual, marketing and individual determinants of customers loyalty. Marketing research was conducted to identify the features of the market behavior of Ukrainian consumers of high-tech products. As the result, the main tends of consumers behavior, external and individual factors of actualization and influence on the consumers motivation were determined. Ukrainian consumers' loyalty was sorted depending on the reasons to buying high-tech products and consumer involvement in this process. Each type of market behavior of consumers corresponds to a certain type of consumer loyalty. Cognitive, agreement, demonstrative loyalty are formed in the case of high consumer involvement in the buying process. Active, perceptual loyalty and loyalty of convenience are observed in the case of low involvement.

    Full Text Available The article is devoted to an important problem in the relations between the Patriarchates of Moscow and Constantinople at the beginning of the 21st century. The author provides a complex analysis of the infl uence exercised by the ecclesiastical crisis in the Ukraine on the relations between Moscow, Phanar and Kiev. Special attention is paid to the activities of non-recognized Ukrainian ecclesiastical structures and their attempts to join the Orthodox world by way of obtaining recognition on the part of the Church of Constantinople. Their frequent joint meetings held at Phanar proved fruitless; however, they were quite illustrative as to the double standards of the Ecumenical Patriarchate in its policies towards the ecclesiastical schisms in the Ukraine. An important role here,according to the author, was played by the Ukrainian civil authorities, although the relations between Church and state as well as the events of the internal ecclesiastical life in the Ukraine (such as the attempted dialogue between the Ukrainian Autonomous Orthodox Church and the Ukrainian Orthodox Church of the Patriarchate of Kiev are left outside the framework of the present research; facts concerning these areas are cited only when they contribute to the understanding of the processes under analysis. Proceeding from the data of Russian and Ukrainian ecclesiastical periodicals, the author maintains that the problem of the religious life in the Ukraine has long ago overstepped the boundaries of a “local confl ict” and that the “Ukrainian question” plays the part of a powerful catalyst in the inter-Orthodox relations. The Patriarchate of Moscow aims at preserving its status in the Orthodox world. As for the Patriarchate of Constantinople, it keeps voicing certain claims at strengthening its position as primus inter pares among the Orthodox Patriarchates, dreams about convening a new “Ecumenical Council” and puts the Ukraine at stake in its relations with

    2016-03-01

    Full Text Available The agrarian crisis in the European part of the Russian Empire in the middle of the 20th century seriously impeded agricultural progress. Agrarian overpopulation and peasants deprived of land in the course of the peasant reform of 1861 further aggravated the negative situation in the governorates of Central Russia, Belarus, and left-bank Ukraine. These factors provided fertile soil for migratory sentiments among peasants. It was resettlement in vacant lands in the Asiatic Russia and North Caucasus, which allowed most of them to preserve their homesteads. In the 2nd half of the 19th – early 20th century, Ukrainian peasants were actively engaged in the migration movement which was supported by the state. One of the main placement areas became Western Siberia where a large Ukrainian peasant community was formed. The history of research on the Ukrainian community in Western Siberia is fragmentary, as many aspects remain unstudied. Hence, the article focuses on the following questions: causes of the Ukrainian migration to the border lands of the Russian Empire; stages in the migration; main areas where Ukrainians resided in Siberia; population dynamics of the Ukrainian community; adaptation patterns specific for Ukrainian migrants in their new places of residence; their role in the economic life of Siberia in the early 20th century. This article utilizes primary data from the All-Russian Agricultural and Land Census of 1917, which have been introduced for scientific use for the first time. As the methodological basis, the study draws on the system approach combining regional, neo-imperial and comparative principles.

    Full Text Available Background. Nowadays, a comprehensive assessment of osteoporosis and the risk of osteoporotic fractures involves the combine use of bone mineral density (BMD, 10-year probability of major osteoporotic fractures (Fracture Risk Assessment Tool, Trabecular Bone Score, and parameters of hip structural ana­lysis. In recent years, reference data on the three above-mentioned methods have been developed for the Ukrainian population, but there are no data on the latest methodology. The objective of the study was to assess the age characteristics of hip structural analysis parameters in Ukrainian women and to offer their reference values for use in clinical practice. Materials and methods. Using the dual energy X-ray absorptiometry method, we examined 690 healthy women aged 20–89 years wi­thout osteoporosis and other clinically significant diseases and conditions affecting the bone metabolism, without other accompanying pathology of hip joint. Results. The results of the study showed a significant effect of age on femoral strength index (FSI, cross-sectional moment of inertia (CSMI, cross-sectional area (CSA, distance from center of femoral head to center of femoral neck (d1, distance from center of femoral head to inter-trochanteric line (d2, mean femoral neck dia­meter (d3, distance from center of mass of femoral neck to superior neck margin (y, shaft angle (a and hip axis length (HAL indices, but not on parameters of neck/shaft angle (q. A significant decrease of FSI with age was established on the background on increase of CSMI, CSA and HAL parameters. Indices of height and body weight were reliably related with parameters of CSMI, CSA and HAL. FSI was significantly related to the body weight, but not to the height. In addition, it reliably correlated with BMD measured at femoral neck and lesser at total hip and lumbar spine. The HAL did not significant correlate with any of the measured BMD, which confirms its independent role in prediction of

Identification of the widespread Ukrainian isolate(s of PVY (Potato virus Y in different potato cultivars and subsequent phylogenetic analysis of detected PVY isolates based on NA and AA sequences of coat protein. Methods. ELISA, RT-PCR, DNA sequencing and phylogenetic analysis. Results. PVY has been identified serologically in potato cultivars of Ukrainian selection. In this work we have optimized a method for total RNA extraction from potato samples and offered a sensitive and specific PCR-based test system of own design for diagnostics of the Ukrainian PVY isolates. Part of the CP gene of the Ukrainian PVY isolate has been sequenced and analyzed phylogenetically. It is demonstrated that the Ukrainian isolate of Potato virus Y (CP gene has a higher percentage of homology with the recombinant isolates (strains of this pathogen (approx. 98.8– 99.8 % of homology for both nucleotide and translated amino acid sequences of the CP gene. The Ukrainian isolate of PVY is positioned in the separate cluster together with the isolates found in Syria, Japan and Iran; these isolates possibly have common origin. The Ukrainian PVY isolate is confirmed to be recombinant. Conclusions. This work underlines the need and provides the means for accurate monitoring of Potato virus Y in the agroecosystems of Ukraine. Most importantly, the phylogenetic analysis demonstrated the recombinant nature of this PVY isolate which has been attributed to the strain group O, subclade N:O.

    Full Text Available The goal of the article is the study of the level of development of the socio-labour sphere of Ukrainian regions. In order to achieve the goal, the article develops a complex scorecard, which takes into account all elements of the socio-labour sphere (socio-labour relations, labour market system of labour reimbursement, social accompaniment of labour activity, professional development of economically active population, level and quality of labour life, safety and security of labour. On the basis of the use of the developed scorecard, the article conducts an integral assessment of the level of development of the socio-labour sphere of regions. In order to get more objective information about the state of the labour sphere of Ukraine, the article uses its subjective assessments by population. In the result of the analysis, it reveals a lack of progressive changes of the socio-labour sphere in majority (60% of Ukrainian regions, availability of significant differentiation of regions by the level of its development and the irregular character of changes of separate elements of the labour sphere both within one administrative and territorial unit and among different regions of Ukraine. The article justifies a necessity of conduct of regular diagnostics of the state of the socio-labour sphere of Ukrainian regions with the use of a developed scorecard.

    Energy issues lie at the heart of Ukraine's economic, political and strategic challenges. A year after the 'orange revolution', the 'gas war' served to highlight the country's vulnerable position, being 80% dependent on imports of gas and having the world's most energy hungry economy. The 2005 crisis also highlighted the extreme opacity of the country's bilateral relations with Russia, which are governed as much by the interests surrounding Gazprom's relations as by those of the state. Yanukovich's return to power in the summer of 2006 coincided with a relative appeasement of relations with Moscow and a new division of spheres of influence in the Ukrainian energy sector. (author)

    In a thermonuclear device for shielding fast neutrons by shielding members disposed in a shielding vessel (vacuum vessel and structures such as a blanket disposed in the vacuum vessel), the shielding member comprises a large number of shielding wires formed fine and short so as to have elasticity. The shielding wires are sealed in a shielding vessel together with water, and when the width of the shielding vessel is changed, the shielding wires follow after the change of the width while elastically deforming in the shielding vessel, so that great stress and deformation are not formed thereby enabling to improve reliability. In addition, the length, the diameter and the shape of each of the shielding wires can be selected in accordance with the shielding space of the shielding vessel. Even if the shape of the shielding vessel is complicated, the shielding wires can be inserted easily. Accordingly, the filling rate of the shielding members can be changed easily. It can be produced more easily compared with a conventional spherical pebbles. It can be produced more easily than existent spherical shielding pebbles thereby enabling to reduce the production cost.

    This work studied the effects of conductivity, magnetic loss, and complex permittivity when using blended textiles (SSF/PET) of polyester fibers (PET) with stainless steel fibers (SSF) on electromagnetic wave shielding mechanisms at electromagnetic wave frequencies ranging from 30 MHz to 1500 MHz. The 316L stainless steel fiber used in this study had 38 vol% γ austenite and 62 vol% α' martensite crystalline phases, which was characterized by an x-ray diffractometer. Due to the magnetic and dielectric loss of soft metallic magnetic stainless steel fiber enabled polyester textiles, the relationship between the reflection/absorption/transmission behaviors of the electromagnetic wave and the electrical/magnetic/dielectric properties of the SSF and SSF/PET fabrics was analyzed. Our results showed that the electromagnetic interference shielding of the SSF/PET textiles show an absorption-dominant mechanism, which attributed to the dielectric loss and the magnetic loss at a lower frequency and attributed to the magnetic loss at a higher frequency, respectively.

    Full Text Available The goal of the article lies in the study of evolution of formation of the risk management system in Ukrainian banks, main instruments, methods of risk management and organisational approaches to formation of subdivisions of risk management and corporate management in banks. Analysing recommendations of the Basel Committee on Banking Supervision, legislative and regulatory acts, which form organisational and methodological requirements by risk management in banks, the article reveals shortcomings of its functioning. The article gives proposals on improvement of riskology in Ukrainian banks, namely: introduction of the requirement for risk assessment and stress testing by banks in the medium-term prospective (up to 3 years, which would reveal risks of realisation of long-term bank programmes, potential losses of receipts and capital due to existing gaps between the terms of performance of obligations by assets and liabilities, etc. In the result of the study the article establishes that in order to realise requirements of the Basel Committee on Banking Supervision on organisation of subdivisions of risk management in banks, it is necessary to introduce qualification requirements to managers of these services and procedures of their assignment/retirement in co-ordination with the banking supervision service, the status of which in the bank is not lower than managers of the internal audit and financial monitoring services, assignment of whom should be mandatory co-ordinated with NBU.

    As a result of the Chernobyl Nuclear Power Plant accident, radioactive fission products have contaminated the food chain in the Ukraine. The highest doses to humans are a result of cesium contamination in milk. The milk produced in the Ukraine contains radioactive cesium at levels up to 10 times the acceptance standards. Bradtec has developed and demonstrated technology for the US Department of Energy for the treatment of groundwater and effluent water. This technology has also been tested and demonstrated for the Ukrainian government for the purpose of treating contaminated milk. Bradtec, a small business offering specialized technologies in the field of environmental remediation and waste management, has successfully worked with a consortium of businesses, National Laboratories and DOE Headquarters staff to develop and implement a technology demonstration strategy which has led to the implementation of a series collaboration agreements with Ukrainian officials. This paper describes, in a case study approach, the path followed by Bradtec and its collaboration partners in successfully implementing a technology transfer strategy. Also presented is an update on new programs that can provide benefit to private sector companies as DOE seeks to assist the private sector in joint venture/technology transfer relationships with the NIS (New Independent States). This paper should be of interest to all businesses seeking to participate in business opportunities in the NIS

The main features of Ukranian literature baroque style that influenced the structure and design of these editions are defined. These features are: allegoric, emblematic, panegyric and theocentric nature of baroque art. Allegory is considered as a structure-forming element of a baroque edition. Emblem presents synthesis of visual and verbal means in baroque artistic book design. Panegyrics become a popular genre of baroque literature, being published as separate editions, as well as a structural part of other editions. Theocentric nature of baroque culture expresses itself mostly in poetic prayers, which function as a common element of preface or afterword to baroque editions. Ukrainian baroque editions are remarkable for their artistic design, which is closely connected to the content of a book.

    Full Text Available The specifics of horizontal and vertical relations in Ukrainian political communication on the background of the party building’s process has been analysed. Aims of this article are: 1 determination of the subjectivity of political communication; 2 disclosure of the main features of internal politics and communications; 3 setting the essential features of the political parties’ status after peaceful protests in Ukraine 2013-2014 year; 4 explanation of the actual gap that has horizontal and party political communication in Ukraine. Political modernization, capacity of Ukrainian political parties has been characterized. It has been shown that Maidan didn’t influenced tools of creating political parties and their typology greatly. Maidan as a political component was weak and did not respond to the challenges, which Ukrainian political system faced to. The weakness was in the fact that leaders of the oppositional political camp would rather keep old then implement real political change of the political system , which was adapted by the old oliharcial clan. Public sector was not able to identify their environment with new political leaders, nor with a mass movement, based on the creation of new organized political force. It has been found that in a democratic society communication is effective only if it is not only technically modern, interactive, two-way, but if it is consistent to other democratic demands, such as legal and moral control of society over the media, maintenance of basic pluralism, direct contact between senders and recipients of information, feeds decentralization, respect of freedom of expression and privat opinion. Summary of the political communication in Ukraine has to move away from thinking of policy and bureaucratic political consciousness. Otherwise, the simulation is effective and efficient for countries and regions where political communication can become a daily political farce communication in public space.

    Introduction: The article is dedicated to the motives of medical career choice studied by Ukrainian and foreign scientists, and by the authors themselves. The authors define the main motives, grouped into the pragmatic, social, scientific and professional ones, paying particular attention to the proposed reforms of the Healthcare of Ukraine "Health 2020". The aim: The study has been aimed at detection of the medical career choice factor groups and their possible correction during the medical training, defining possible influence of the Ukrainian Healthcare reformation onto alterations of the medical career choice. Materials and methods: This article is based on bibliosemantic, dialectical, comparative, analytic, synthetic and comprehensive research methods. Review and conclusion: The authors have analyzed medical career motives according to the A. Maslow hierarchy of needs, comparing the present motives with the motives to be changed after reforming the Ukrainian healthcare. The authors conclude that according to the Maslow's hierarchy of needs, the medical career choice corresponding to the first, second and third needs level would be directly related to the pragmatic, social and scientific motives, further disappointment in career, low professional performance and professional "burnout". The career choice corresponding to the last levels of the needs hierarchy is related to the professional motives and self-actualization, but, due to the applicants' age and financial status of medical specialists in Ukraine, is not likely to occur. Positive changes in medical specialists' salary rise, social protection offered by the State and state support of the profession will provide for correction of motives onto the higher level, in this way, benefiting the patients.

    The radiation shielding concretes comprise water, cement, fine aggregates consisting of serpentines and blown mist slags, coarse aggregates consisting of serpentines and kneading materials. Since serpentines containing a relatively great amount of water of crystallization in rocks as coarse aggregates and fine aggregates, the hydrogen content in the radiation shielding concretes is increased and the neutron shielding effect is improved. In addition, since serpentines are added as the fine aggregates and blown mists slags of a great specific gravity are used, the specific gravity of the shielding concretes is increased to improve the γ-ray shielding effect. Further, by the use of the kneading material having a water reducing effect and fluidizing effect, and by the bearing effect of the spherical blown mist slags used as the fine aggregates, concrete fluidity can be increased. Accordingly, workability of the radiation shielding concretes can be improved. (T.M.)

    Extensive radiation field surveys were conducted in NAPS and KAPS reactor buildings as a part of commissioning checks on radiation shielding. During such surveys, dose rate higher than the expected values were noticed in fuelling machine service areas. A movable shield, separating high field area fuelling machine vault and low field area fuelling machine service area, known as roll-on shield was identified as one of the causes of high field in fuelling machine service area along with weaker end-shield. This paper discusses systematic approach adopted in bringing down the dose rates in fuelling machine service area by augmentation of roll-on shield. (author)

    No comprehensive data on sources or risk factors of cadmium exposure in Ukrainian children are available. In this we measured the blood levels of cadmium among 80 Ukrainian children and evaluated sources of exposure. A nested case-control study from a prospective cohort of Ukrainian 3-year-old children was conducted. We evaluated predictors of elevated blood cadmium using a multivariable logistic regression model. The model included socioeconomic data, parent occupation, environmental tobacco smoke, hygiene, body-mass index, and diet. Dietary habits were evaluated using the 1992 Block-NCI-HHHQ Dietary Food Frequency survey. Elevated cadmium was defined as blood levels in the upper quartile (>=0.25μg/L). The mean age for all 80 children was 36.6 months. Geometric mean cadmium level was 0.21μg/L (range=0.11-0.42μg/L; SD=0.05). Blood cadmium levels were higher among children taking zinc supplements (0.25 vs 0.21μg/L; P=0.032), children who ate sausage more than once per week (0.23 vs 0.20; P=0.007) and children whose fathers worked in a by-product coking industry (0.25 vs 0.21; P=0.056). In the multivariable model, predictors of elevated blood cadmium levels included zinc supplementation (adjusted OR=14.16; P<0.01), father working in a by-product coking industry (adjusted OR=8.50; P=0.03), and low body mass index (<14.5; adjusted OR=5.67; P=0.03). This is the first study to indicate a strong association between elevated blood cadmium levels and zinc supplementation in young children. Whole-blood cadmium levels observed in this group of Ukrainian children appear to be similar to those reported in other Eastern European countries

    2003-01-01

    The heat flux from both gas convection and chamber radiation on a direct drive target must be limited to avoid target damage from excessive D-T temperature increase. One of the possibilities of protecting the target is a wake shield flying in front of the target. A shield will also reduce drag force on the target, thereby facilitating target tracking and position prediction. A Direct Simulation Monte Carlo (DSMC) code was used to calculate convection heat loads as boundary conditions input into ANSYS thermal calculations. These were used for studying the quality of target protection depending on various shapes of shields, target-shield distance, and protective properties of the shield moving relative to the target. The results show that the shield can reduce the convective heat flux by a factor of 2 to 5 depending on pressure, temperature, and velocity. The protective effect of a shield moving relative to the target is greater than the protective properties of a fixed shield. However, the protective effect of a shield moving under the drag force is not sufficient for bringing the heat load on the target down to the necessary limit. Some other ways of diminishing heat flux using a protective shield are discussed

    Full Text Available The article is devoted to urgent problems of demographic development of rural areas, their impact on socioeconomic processes at all levels of the national economic system. The content of demographic and economic antonyms of «demographic development» and «demographic catastrophe» has been characterized. The article analyzes the historical background of demographic change in rural areas, their socio-economic consequences. It’s reasonably concluded that the economic development of Ukraine requires urgent settlement of the negative socio-demographic trends that are characteristic for a Ukrainian village. Nowadays, these trends are of a destructive nature. They lead to a protracted crisis of agricultural production which is very difficult to overcome solely with the tools of technical and technological modernization. This will complicate the food security of the state for many years; lower the level and quality of life of the population, lead to greater territorial disparities and degradation of rural areas and the marginalization of residents of Ukrainian villages.

    Cho, Yong In; Kim, Ja Mee; Kim, Jung Hoon

    2017-01-01

    To better understand the distribution of deposited energy of beta and gamma rays according to changes in shielding materials and thicknesses when radionuclides are used for therapeutic nuclear medicine, a simulation was conducted. The results showed that due to the physical characteristics of each therapeutic radionuclide, the thicknesses of shielding materials at which beta-ray shielding takes place varied. Additional analysis of the shielding of gamma ray was conducted for radionuclides that emit both beta and gamma rays simultaneously with results showing shielding effects proportional to the atomic number and density of the shielding materials. Also, analysis of bremsstrahlung emission after beta-ray interactions in the simulation revealed that the occurrence of bremsstrahlung was relatively lower than theoretically calculated and varied depending on different radionuclides.

    2014-01-01

    The objective of this report is to address and describe the problematic of the Ukrainian gas transit within a wider inner context and under the light of the current gas crisis. Beyond the European security of supply, maintaining the gas transit is a major domestic issue for Ukraine, from an economic as well as political point of view. This means that, in order to avoid a new gas crisis, Ukraine must significantly reform its energy sector in order to reduce its dependency and to re-balance its energy mix. In a first part, the author discusses gas price and transit network management as the main stakes of the gas crisis: recall of traditional dispute about gas between Russia and Ukraine, ageing and corruption as characteristics of a collapsing gas corridor, the Ukrainian law of September 2014 as a first step for a reform of energy governance. In a second part, the author discusses the future of the Ukrainian gas sector and the issue of stability of the national energy system. This should be based on short term options to strengthen the resilience of the gas sector in front of Russian supply disruption, a priority for a gas independence, and necessary review of the energy mix

    The George Kuzmycz Training Center for Physical Protection, Control and Accounting of Nuclear Material (GKTC) was established in October 1998 at the Kiev Institute for Nuclear Research. During the past six years, about 700 professionals from all Ukrainian nuclear installations, executive and regulatory bodies were trained at the GKTC. Future Material Control and Accounting (MC and A) training courses are going to be held even more frequently because Ukraine has already signed the Additional Model Protocol and its ratification by Ukrainian Parliament is expected to happen very soon. Additionally, a number of new training courses will be developed. US DOE trough Argonne National Laboratory has made significant efforts to transfer Automated Inventory/Material Accounting System (AIMAS) software to Ukraine. As a result, AIMAS software can be used as a basic code for the development of the Computerized MC and A System for all Ukrainian nuclear facilities despite their differences. In 2003, a new laboratory for Nondestructive Assay (NDA) was established with assistance from the U.S. Department of Energy. As a result, GKTC training capabilities will increase substantially. Furthermore, in order to increase the efficiency of NDA laboratory, it is planned to use the NDA equipment for a program of interdiction of illicit traffic of nuclear materials in Ukraine. American-Ukrainian MC and A efforts for the last 6 years, the problems encountered and the solutions to these problems, as well as comments, suggestions and recommendations for future activity at GKTC to promote and improve the nuclear material management culture in Ukraine are discussed in detail.

    The cold neutron research facility in HANARO is under construction. The area including neutron guides and rotary shutter in the reactor hall should be shielded by the guide shielding assembly which is constructed of heavy concrete blocks and structure. The guide shielding assembly is divided into 2 parts, A and B. Part A is about 6.4 meters apart from the reactor biological shield and it is constructed of heavy concrete blocks whose density is above 4.0g/cm 3 . And part B is a fixed heavy concrete structure whose density is above 3.5g/cm 3 . The rotary shutter is also made with heavy concrete whose density is above 4.0g/cm 3 and includes 5 neutron guides inside. It can block the neutron beam by rotating when CNS is not operating. The dose criterion outside the guide shielding assembly is established as 12.5 μSv/hr which is also applied to reactor shielding in HANARO

    Third generation high brightness light sources are designed to have low emittance and high current beams, which contribute to higher beam loss rates that will be compensated by Top-Off injection. Shielding for these higher loss rates will be critical to protect the projected higher occupancy factors for the users. Top-Off injection requires a full energy injector, which will demand greater consideration of the potential abnormal beam miss-steering and localized losses that could occur. The high energy electron injection beam produce significantly higher neutron component dose to the experimental floor than lower energy injection and ramped operations. High energy neutrons produced in the forward direction from thin target beam losses are a major component of the dose rate outside the shield walls of the tunnel. The convention has been to provide thicker 90° ratchet walls to reduce this dose to the beam line users. We present an alternate circular shield wall design, which naturally and cost effectively increases the path length for this forward radiation in the shield wall and thereby substantially decreasing the dose rate for these beam losses. This shield wall design will greatly reduce the dose rate to the users working near the front end optical components but will challenge the beam line designers to effectively utilize the longer length of beam line penetration in the shield wall. Additional advantages of the circular shield wall tunnel are that it's simpler to construct, allows greater access to the insertion devices and the upstream in tunnel beam line components, as well as reducing the volume of concrete and therefore the cost of the shield wall.

    1983-01-01

    Purpose: To reduce the weight and stabilize the configuration of a radiation shielding plate which is used in close contact with an object to be irradiated with radiation rays. Constitution: The radiation shielding plate comprises a substrate made of lead glass and a metallic lead coating on the surface of the substrate by means of plating, vapor deposition or the like. Apertures for permeating radiation rays are formed to the radiation shielding plate. Since the shielding plate is based on a lead glass plate, a sufficient mechanical strength can be obtained with a thinner structure as compared with the conventional plate made of metallic lead. Accordingly, if the shielding plate is disposed on a soft object to be irradiated with radiation rays, the object and the plate itself less deform to obtain a radiation irradiation pattern with distinct edges.

    Russell, G.J.

    1989-01-01

    I calculated neutron and gamma-ray equivalent doses leaking through a variety of infinite (laminate) slab-shields. In the shield computations, I used, as the incident neutron spectrum, the leakage spectrum (<20 MeV) calculated for the LANSCE tungsten production target at 90 degree to the target axis. The shield thickness was fixed at 60 cm. The results of the shield calculations show a minimum in the total leakage equivalent dose if the shield is 40-45 cm of iron followed by 20-15 cm of borated (5% B) polyethylene. High-performance shields can be attained by using multiple laminations. The calculated dose at the shield surface is very dependent on shield material. 4 refs., 4 figs., 1 tab

    2011-01-01

    The shielding calculations for RTP fuel transfer cask was performed by using computer code Micro shield 7.02. Micro shield is a computer code designed to provide a model to be used for shielding calculations. The results of the calculations can be obtained fast but the code is not suitable for complex geometries with a shielding composed of more than one material. Nevertheless, the program is sufficient for As Low As Reasonable Achievable (ALARA) optimization calculations. In this calculation, a geometry based on the conceptual design of RTP fuel transfer cask was modeled. Shielding material used in the calculations were lead (Pb) and stainless steel 304 (SS304). The results obtained from these calculations are discussed in this paper. (author)

    2017-07-01

    In some cases, the former social-ethnic identification was weakened or completely lost, while in others it was reinforced or even arose for the first time. A relationship has been found between the type of identification with the reference groups, as well as the way of their use, on the one hand, and the degree of social adaptation of migrants, on the other. As a result, several trends have been identified. First, the situation of dynamic social progress due to the reliance on identification associated with the reference groups in Ukraine at the stage of initial adaptation. Second, the tendency towards disintegration with American society and narrowing the chances of social mobility, due to the closure of the social-cultural patterns of Ukrainian society in the later stages of social adaptation. Third, the situation of simultaneous social advancement and maintaining close ties with reference groups in Ukraine due to acquiring a social status, confirmed by active participation in civil initiatives in Ukraine or Ukrainian-American projects. Fourth, the expansion of social opportunities for migrants, due to the integration of Ukrainian reference groups into a system of new ones, connected with American society.

    1959-02-17

    Radiation shield construction is described for a nuclear reactor. The shield is comprised of a plurality of steel plates arranged in parallel spaced relationship within a peripheral shell. Reactor coolant inlet tubes extend at right angles through the plates and baffles are arranged between the plates at right angles thereto and extend between the tubes to create a series of zigzag channels between the plates for the circulation of coolant fluid through the shield. The shield may be divided into two main sections; an inner section adjacent the reactor container and an outer section spaced therefrom. Coolant through the first section may be circulated at a faster rate than coolant circulated through the outer section since the area closest to the reactor container is at a higher temperature and is more radioactive. The two sections may have separate cooling systems to prevent the coolant in the outer section from mixing with the more contaminated coolant in the inner section.

    Santos, Romulo R.; Real, Jessica V.; Luz, Renata M. da; Friedrich, Barbara Q.; Silva, Ana Maria Marques da

    2013-01-01

    In shielding calculation of radiological facilities, several parameters are required, such as occupancy, use factor, number of patients, source-barrier distance, area type (controlled and uncontrolled), radiation (primary or secondary) and material used in the barrier. The shielding design optimization requires a review of several options about the physical facility design and, mainly, the achievement of the best cost-benefit relationship for the shielding material. To facilitate the development of this kind of design, a program to calculate the shielding in diagnostic radiology was implemented, based on data and limits established by National Council on Radiation Protection and Measurements (NCRP) 147 and SVS-MS 453/98. The program was developed in C⌗ language, and presents a graphical interface for user data input and reporting capabilities. The module initially implemented, called SHIELD 1.0, refers to calculating barriers for conventional X-ray rooms. The program validation was performed by the comparison with the results of examples of shielding calculations presented in NCRP 147.

    2016-09-08

    The purpose of this study was to introduce and describe the development of RadShield, a Java-based graphical user interface (GUI), which provides a base design that uniquely performs thorough, spatially distributed calculations at many points and reports the maximum air-kerma rate and barrier thickness for each barrier pursuant to NCRP Report 147 methodology. Semiautomated shielding design calculations are validated by two approaches: a geometry-based approach and a manual approach. A series of geometry-based equations were derived giv-ing the maximum air-kerma rate magnitude and location through a first derivative root finding approach. The second approach consisted of comparing RadShield results with those found by manual shielding design by an American Board of Radiology (ABR)-certified medical physicist for two clinical room situations: two adjacent catheterization labs, and a radiographic and fluoroscopic (R&F) exam room. RadShield's efficacy in finding the maximum air-kerma rate was compared against the geometry-based approach and the overall shielding recommendations by RadShield were compared against the medical physicist's shielding results. Percentage errors between the geometry-based approach and RadShield's approach in finding the magnitude and location of the maximum air-kerma rate was within 0.00124% and 14 mm. RadShield's barrier thickness calculations were found to be within 0.156 mm lead (Pb) and 0.150 mm lead (Pb) for the adjacent catheteriza-tion labs and R&F room examples, respectively. However, within the R&F room example, differences in locating the most sensitive calculation point on the floor plan for one of the barriers was not considered in the medical physicist's calculation and was revealed by the RadShield calculations. RadShield is shown to accurately find the maximum values of air-kerma rate and barrier thickness using NCRP Report 147 methodology. Visual inspection alone of the 2D X-ray exam distribution by a medical physicist may not

The inlet, outlet and side primary shields were constructed in-place using 2.54 cm (1 in) thick steel plates as the forms. The plates remained as an integral part of the shields. The elongation of the pressure tubes due to thermal expansion and pressurization is not moving through the inlet nozzle hardware as designed but is accommodated by outward displacement and bowing of the inlet and outlet shields. Excessive distortion of the shields may result in gas seal failures, intolerable helium gas leaks, increased argon-41 emissions, and shield cooling tube failures. The shield surveillance and testing results are presented

    In the new plants (Narora Atomic Power Plants (NAPP) onwards) relatively higher radiation fields exist on the north and south fuelling machine (FM) vault walls of the E1 100m accessible area passages. These fields were first noticed at NAPS-1 and subsequently at NAPS-2 and KAPS-1. Such surveys done at RAPS have indicated that the fields on these walls would come out to be quite low (only 1-2 mR/h) from sources other than that arising from 41 Ar contamination. RAPS/MAPS experience pointed to adequacy of shielding of the FM vault walls and sufficient overall shielding thickness of the end-shields. Further, radiometry tests of end-shields carried out at Kaiga and RAPP 3 and 4 indicated fairly satisfactory and uniform filling of balls. Hence, incomplete filling of water column of the end-shields due to any venting problem was suspected to be one possible reason for the observed high fields in NAPS and Kakrapar Atomic Power Station (KAPS). Since the presence of high radiation fields, both neutron and gamma, is of long-term concern, a special study/measurement of radiation levels on reactor face during high power operation was undertaken. In order to compare the shielding integrity of the older (RAPS/MAPS solid plate type shielding) and newer (NAPS/KAPS steel ball-filled type) end shields, these experiments were done at MAPS-2 and NAPS-2.

  10. Magnetic shielding for superconducting RF cavities

    Magnetic shielding is a key technology for superconducting radio frequency (RF) cavities. There are basically two approaches for shielding: (1) surround the cavity of interest with high permeability material and divert magnetic flux around it (passive shielding); and (2) create a magnetic field using coils that cancels the ambient magnetic field in the area of interest (active shielding). The choice of approach depends on the magnitude of the ambient magnetic field, residual magnetic field tolerance, shape of the magnetic shield, usage, cost, etc. However, passive shielding is more commonly used for superconducting RF cavities. The issue with passive shielding is that as the volume to be shielded increases, the size of the shielding material increases, thereby leading to cost increase. A recent trend is to place a magnetic shield in a cryogenic environment inside a cryostat, very close to the cavities, reducing the size and volume of the magnetic shield. In this case, the shielding effectiveness at cryogenic temperatures becomes important. We measured the permeabilities of various shielding materials at both room temperature and cryogenic temperature (4 K) and studied shielding degradation at that cryogenic temperature.

    Full Text Available The purpose of the research is to identify the influence of Ukraine’s economic development on the international agencies' credit rating of its banking system. The instability and ambiguous geopolitical position of Ukraine are complicating any predictions for its economic developments. In the meanwhile, massive restructuring of all sectors of the economy became the necessary minimum for the reformation of the country and the achievement of the international standards. It is interesting to see how exactly these international standards, as represented by the evaluation of the rating agencies, appraise Ukraine, and particularly its banking sector. The methodology involves the analysis of the three major Ukrainian banks – PrivatBank, Oschadbank, and Ukreximbank using Fitch’s credit quality assessment systematic as an example. The comparative analysis was performed using Tier 1 capital ratio and loan-to-deposit ratio of these banks, year-to-year quarterly GDP growth, consumer price index (CPI year-to-year change, UAH/USD exchange rate, 2-year and 5-year government bond yield, as well as 2-year and 5-year credit default swap (CDS. Results show that the most influential credit rating drivers for Ukrainian banks are: exchange rate; funding and liquidity; capital position and asset quality; sovereign risk. The research showed that the 2-year and 5-year government bond yield in USD and 2-year and 5-year CDS were influenced by similar trends. The yield on short-dated Ukrainian governmental bonds has shown a parallel increase with the corresponding CDS that indicated the market’s evaluation of the stressed condition of the country’s government and economy. Additionally, conventional yield structures displayed inversed nature with 2-year governmental bond yield in USD trading at significantly higher yields than 5-year government bond yield in USD during times of economic distress. Although longer maturity instruments should usually trade at a higher

    Full Text Available The purpose of this paper is to show features of formation of Ukrainian education policy. According to the author, the formation of the national education policy in Ukraine, as the European Union in its time, must find the thin boundary i.e. the balance between unity and dissimilarity of two dif erent education systems such as Soviet education system, which was inherited after the collapse of the Soviet Union, and European education system, which was unified by requirements of the Bologna Declaration. The author examines the features of the formation and development of Soviet and European education systems. Each of them has certain advantages and disadvantages. The author also presents that major educational reforms, which were only started in Ukraine, took place in Central and Eastern Europe in the late twentieth century. This process was caused by the collapse of bipolar world and scores of countries, which were formed in Europe and sought to European values and democratic reforms. Poland, Hungary, Romania, Slovenia and many other new independent states, which paid in full for socialist regimes, began reforms in education, politics, economics and other areas of activity. We can confidently say that the education system in the new founding countries of Europe not only shifted from one model (Soviet model to another (European model, but rather to achieve high performance in their development. The author points out that it is necessary to require continuing professional development of all categories of people, from teachers to car drivers. This growth must be accompanied with the received diplomas at the reputable higher educational institutions not only in Ukraine, but also abroad. Through this paper the author also wants to suggest that the main provisions of national education policy Ukraine is based on Ukrainian national idea. This national idea sounds as «Ukraine is as keeper of harmony between Eastern and Western Europe».

    Western Arabia lies within the low-latitude desert of north Africa and the Middle East, the core being the Arabian segment of the African Shield. The core of complex basement rocks accounts for about 670,000 km2, or one-third of the Arabian Peninsula. Reconnaissance mapping of these crystalline rocks, together with bordering sedimentary rocks and volcanic flows, begun in 1950, resulted during the next 13 years in a series of geologic and geographic maps without extensive texts. The maps served as general guides for development of natural resources, including water supplies, ore deposits, and building materials. An intensive exploration program that began in 1963 and involved numerous geologists has vastly increased geologic information.

  18. Shielding in experimental areas

    Stevens, A.; Tarnopolsky, G.; Thorndike, A.; White, S.

    1979-01-01

    The amount of shielding necessary to protect experimental detectors from various sources of background radiation is discussed. As illustrated an experiment has line of sight to sources extending approx. 90 m upstream from the intersection point. Packing a significant fraction of this space with shielding blocks would in general be unacceptable because primary access to the ring tunnel is from the experimental halls. (1) From basic machine design considerations and the inherent necessity to protect superconducting magnets it is expected that experimental areas in general will be cleaner than at any existing accelerator. (2) Even so, it will likely be necessary to have some shielding blocks available to protect experimental apparatus, and it may well be necessary to have a large amount of shielding available in the WAH. (3) Scraping will likely have some influence on all halls, and retractable apparatus may sometimes be necessary. (4) If access to any tunnel is needed to replace a magnet, one has 96 h (4 days) available to move shielding away to permit access without additional downtime. This (the amount of shielding one can shuffle about in 96 h) is a reasonable upper limit to shielding necessary in a hall

    1992-01-01

    Crystalline silica is the scientific name for a group of minerals composed of silicon and oxygen. The term crystalline refers to the fact that the oxygen and silicon atoms are arranged in a threedimensional repeating pattern. This group of minerals has shaped human history since the beginning of civilization. From the sand used for making glass to the piezoelectric quartz crystals used in advanced communication systems, crystalline silica has been a part of our technological development. Crystalline silica's pervasiveness in our technology is matched only by its abundance in nature. It's found in samples from every geologic era and from every location around the globe. Scientists have known for decades that prolonged and excessive exposure to crystalline silica dust in mining environments can cause silicosis, a noncancerous lung disease. During the 1980's, studies were conducted that suggested that crystalline silica also was a carcinogen. As a result of these findings, crystalline silica has been regulated under the Occupational Safety and Health Administration's (OSHA) Hazard Communication Standard (HCS). Under HCS, OSHAregulated businesses that use materials containing 0.1% or more crystalline silica must follow Federal guidelines concerning hazard communication and worker training. Although the HCS does not require that samples be analyzed for crystalline silica, mineral suppliers or OSHAregulated

    Full Text Available The article presents challenges and methods of teacher training activities aimed to develop communicative competence and prepare teachers for work in mountain area schools in the Ukrainian Carpathians. Research shows that specifics of social and cultural environment should be taken into account in the process of teaching native language and developing communicative competence of future teachers. Sociocultural approach defines language teaching strategies in the light of national culture, traditions of ethnic regions and the Ukrainian Carpathians in particular. Teacher training programs should include studies on material, cultural and spiritual values of highlanders. Such topics can be incorporated in the main native language course. Study and analysis of fiction pieces, especially those that reflect the socio-cultural peculiarities of linguistic community of the Ukrainian Carpathians can be of great value in achieving the goal. Small classes in mountain schools also place a demand upon educators to constantly upgrade approaches, forms and methods of teaching. The article offers an integral teacher training system aimed at developing communicative competence and preparing teachers to work in the mountain areas schools. A special place in this system is given to folk pedagogy, which accumulates the national and regional spiritual values. The author presents the components of communicative and socio-cultural competence of future teachers. The suggested algorithm for training primary school teachers insures reaching an appropriate level of socio-cultural, historical, linguistic and communicative competencies necessary for language teaching at primary schools in mountain regions of the Ukrainian Carpathians.

    1983-01-01

    The repair works of the shielding for the nuclear ship ''Mutsu'' were completed in August, 1982. For the primary shielding, serpentine concrete was adopted as it contains a large quantity of water required for neutron shielding, and in the secondary shielding at the upper part of the reactor containment vessel, the original shielding was abolished, and the heavy concrete (high water content, high density concrete) which is effective for neutron and gamma-ray shielding was newly adopted. In this report, the design and construction using these shielding concrete are outlined. In September, 1974, Mutsu caused radiation leak during the test, and the cause was found to be the fast neutrons streaming through a gap between the reactor pressure vessel and the primary shielding. The repair works were carried out in the Sasebo Shipyard. The outline of the repair works of the shielding is described. The design condition for the shielding, the design standard for the radiation dose outside and inside the ship, the method of shielding analysis and the performance required for shielding concrete are reported. The selection of materials, the method of construction and mixing ratio, the evaluation of the soundness and properties of concrete, and the works of placing the shielding concrete are outlined.

    1989-01-01

    The increased use of nuclear energy has given rise to a growth in the amount of artificially produced radiation and radioactive materials. The design and construction of shielding to protect people, equipment and structures from the effects of radiation has never been more important. Experience has shown that concrete is an effective, versatile and economical material for the construction of radiation shielding. This book provides information on the principles governing the interaction of radiation with matter and on relevant nuclear physics to give the engineer an understanding of the design and construction of concrete shielding. It covers the physical, mechanical and nuclear properties of concrete; the effects of elevated temperatures and possible damage to concrete due to radiation; basic procedures for the design of concrete radiation shields and finally the special problems associated with their construction and cost. Although written primarily for engineers concerned with the design and construction of concrete shielding, the book also reviews the widely scattered data and information available on this subject and should therefore be of interest to students and those wishing to research further in this field.

    The Carpathians are part of the Alpine-Carpathian-Dinaridic orogen surrounding the Pannonian basin. Their Ukrainian part constitutes an ancient subduction-accretion complex that evolved into a foreland fold-thrust belt with a shortening history that was perpendicular to the orogenic strike. Herein, we constrain the evolution of the Ukrainian part of the Carpathian fold-thrust belt by apatite fission-track dating of sedimentary and volcanic samples and cross-section balancing and restoration. The apatite fission-track ages are uniform in the inner―southwestern part of the fold-thrust belt, implying post-shortening erosion since 12-10 Ma. The ages in the leading and trailing edges record provenance, i.e., sources in the Trans-European suture zone and the Inner Carpathians, respectively, and show that these parts of the fold-thrust were not heated to more than 100 °C. Syn-orogenic strata show sediment recycling: in the interior of the fold-thrust belt―the most thickened and most deeply eroded nappes―the apatite ages were reset, eroded, and redeposited in the syn-orogenic strata closer to the fore- and hinterland; the lag times are only a few million years. Two balanced cross sections, one constructed for this study and based on field and subsurface data, reveal an architecture characterized by nappe stacks separated by high-displacement thrusts; they record 340-390 km shortening. A kinematic forward model highlights the fold-thrust belt evolution from the pre-contractional configuration over the intermediate geometries during folding and thrusting and the post-shortening, erosional-unloading configuration at 12-10 Ma to the present-day geometry. Average shortening rates between 32-20 Ma and 20-12 Ma amounted to 13 and 21 km/Ma, respectively, implying a two-phased deformation of the Ukrainian fold-thrust belt.

    Full Text Available This article reviews research on the Holodomor by historians of Ukraine since the late 1980s. It examines the dominant trends in historiography, the major findings, and the current state of the field. The field itself, it argues, has grown considerably and there now exists a critical body of scholarship on the subject. For the past two decades, this scholarship has largely been dominated by the debate about whether the Holodomor constitutes genocide. Much of the focus has been on illuminating the policies, methods, and intentions of the Soviet leadership and there have been notable advances in these areas of research. Social history on this topic, on the other hand, remains largely underdeveloped. Some historians of Ukraine have begun to study the Holodomor “from below” and to explore the larger social and cultural consequences of de-kulakization, collectivization, and the Terror-Famine. This approach is crucial, the author suggests, to understanding the exceptional nature of the era. In terms of patterns of migration, family structure, religious practices, social identity, status and ranking, and attitudes towards power, authority, and political participation, the Holodomor Era fundamentally changed the way Ukrainians lived. In this respect, it represents a turning point, as momentous as perhaps any in Ukrainian history.

    The nuclear material (Pyro, Spent nuclear fuel) itself and the target material to generate neutrons is the LSDS system for isotopic fissile assay release of high intensity neutron and gamma rays. This research was performed to shield from various strong radiation. A shielding evaluation was carried out with a facilities model of LSDS system. The MCNPX 2.5 code was used and a shielding evaluation was performed for the shielding structure and location. The radiation dose based on the hole structure and location of the wall was evaluated. The shielding evaluation was performed to satisfy the safety standard for a normal person (1 μSv/h) and to use enough interior space. The MCNPX2.5 code was used and a dose evaluation was performed for the location of the shielding material, shielding structure, and hole structure. The evaluation result differs according to the shielding material location. The dose rate was small when the shielding material was positioned at the center. The dose evaluation result regarding the location of the shielding material was applied to the facility and the shielding thickness was determined (In 50 cm + Borax 5 cm + Out 45cm). In the existing hole structure, the radiation leak is higher than the standard. A hole structure model to prevent leakage of radiation was proposed. The general public dose limit was satisfied when using the concrete reinforcement and a zigzag structure. The shielding result will be of help to the facility shielding optimization.

    The Clinch River Breeder Reactor Plant (CRBRP) is being designed as a fast breeder demonstration project in the U.S. Liquid Metal Fast Breeder Reactor (LMFBR) program. Radiation shielding design of the facility consists of a comprehensive design approach to assure compliance with design and government regulatory requirements. Studies conducted during the CRBRP design process involved the aspects of radiation shielding dealing with protection of components, systems, and personnel from radiation exposure. Achievement of feasible designs, while considering the mechanical, structural, nuclear, and thermal performance of the component or system, has required judicious trade-offs in radiation shielding performance. Specific design problems which have been addressed are in-vessel radial shielding to protect permanent core support structures, flux monitor system shielding to isolate flux monitoring systems for extraneous background sources, reactor vessel support shielding to allow personnel access to the closure head during full power operation, and primary heat transport system pipe chaseway shielding to limit intermediate heat transport system sodium system coolant activation. The shielding design solutions to these problems defined a need for prototypic or benchmark experiments to provide assurance of the predicted shielding performance of selected design solutions and the verification of design methodology. Design activities of CRBRP plant components an systems, which have the potential for radiation exposure of plant personnel during operation or maintenance, are controlled by a design review process related to radiation shielding. The program implements design objectives, design requirements, and cost/benefit guidelines to assure that radiation exposures will be ''as low as reasonably achievable''

    To verify the Monte Carlo code MCNP4A as a tool to generate the reference data in the shielding designs and the safety evaluations, various shielding benchmark experiments were analyzed using this code. These experiments were categorized in three types of the shielding subjects; bulk shielding, streaming, and skyshine. For the variance reduction technique, which is indispensable to get meaningful results with the Monte Carlo shielding calculation, we mainly used the weight window, the energy dependent Russian roulette and spitting. As a whole, our analyses performed enough small statistical errors and showed good agreements with these experiments. (author)

    1988-01-01

    Reactor shielding for multimegawatt (MMW) space power must satisfy a mass constraint as well as performance specifications for neutron fluence and gamma dose. A minimum mass shield is helpful in attaining the launch mass goal for the entire vehicle, because the shield comprises about 1% to 2% of the total vehicle mass. In addition, the shield internal heating must produce tolerable temperatures. The analysis of shield performance for neutrons and gamma rays is emphasized. Topics addressed include cross section preparation for multigroup 2D S/sub n/-transport analyses, and the results of parametric design studies on shadow shield performance and mass versus key shield design variables such as cone angle, number, placement, and thickness of layers of tungsten, and shield top radius. Finally, adjoint methods are applied to the shield in order to spatially map its relative contribution to dose reduction, and to provide insight into further design optimization. 7 refs., 2 figs., 3 tabs

    1977-01-01

    The effect of introducing a neutron and gamma shield into the annulus between the reactor vessel and the shield tank is analyzed. This addition has been proposed in order to intercept neutron streaming up the annulus during nuclear operations. Its installation will require removal of approximately 20- 1 / 2 inches of stainless steel foil insulation at the top of the annulus. The resulting conduction path is believed to result in increased water temperatures within the shield tank, possibly beyond the 150 0 F limit, and/or cooling of the reactor vessel nozzles such that adverse thermal stresses would be generated. A two dimensional thermal analysis using the finite element code COUPLE/MOD2 was done for the shield tank system illustrated in the figure (1). The reactor was assumed to be at full power, 55 MW (th), with a loop flow rate of 2.15 x 10 6 lbm/hr (268.4 kg/s) at 2250 psi (15.51 MPa). Calculations indicate a steady state shield tank water temperature of 140 0 F (60 0 C). This is below the 150 0 F (65.56 0 C) limit. Also, no significant changes in thermal gradients within the nozzle or reactor vessel wall are generated. A spacer between the gamma shield and the shield tank is recommended, however, in order to ensure free air circulation through the annulus

  17. An Anthology as a Representative Genre in Contemporary Ukrainian Literature

    Full Text Available In this article is analyzed a history and functions of an anthology in a modern Ukrainian literature from the last quarter of the 19th c. to the beginning of the 21st. An anthology is treated as a literary and anthropological project which is characterized by recasting of original materials and specific politics of its re-arangement. It proposes a new cultural value hierarchy, defines a literary field and the rules of its organization. As a form of literary self-representation an anthology participates in a process of forming a literary tradition and canon, its diversification up to the emergence of anti-canon; it intensifies a work of cultural memory, represents new literary genres and styles and also indicates an appearance of diaspora as a model of cultural citizenship. Numerous anthological projects also stress spacial, performative, subjective, gender, erotical, somatic, and oneirological aspects of creative writing; they rethink a very nature of literature as a creative experiment and as a social action in a context of mass culture and new media development. This allows us to consider the literary anthology as a way of a literary self-reflection and as a separate meta-genre in modern Ukrainian literature. The main genre-defining anthological qualities are such as selectivity, double methonimity, integrity and an ability to create new cultural values. The history of anthology as a specific meta-genre helps us to understand the general pecularities of modenr and postmodern literature, its structure and principles of development, its key problems and challanges and also its the most important achievements.

    The nuclear ship ''Mutsu'' was constructed in 1970 as the fourth in the world. On September 1, 1974, during the power raising test in the Pacific Ocean, radiation leak was detected. As the result of investigation, it was found that the cause was the fast neutrons streaming through the gap between the reactor pressure vessel and the primary shield. In order to repair the shielding facility, the Japan Nuclear Ship Research Development Agency carried out research and development and shielding design. It was decided to adopt serpentine concrete for the primary shield, which is the excellent moderator of fast neutrons even at high temperature, and heavy concrete for the secondary shield, which is effective for shielding both gamma ray and neutron beam. The repair of shielding was carried out in the Sasebo Shipyard, and completed in August, 1982. The outline of the repair work is reported. The weight increase was about 300 t. The conditions of the shielding design, the method of shielding analysis, the performance required for the shielding concrete, the preliminary experiment on heavy concrete and the construction works of serpentine concrete and heavy concrete are described.

    Full Text Available In spite of a great number of patented formulas of catalysts for neutralization of carbon monoxide (CO which is the most widespread atmospheric pollutant, only batch-produced hopcalite and alumina supported palladium (Pd/Al2O3 are used in practice. The named catalysts have significant defects: hopcalite is poisonable in the presence of water vapor and Pd/Al2O3 is characterized by the great content of palladium. We have found the possibility of using inexpensive Ukrainian natural sorbents differing by their mineralogical and chemical compositions, i.e. zeolites, bentonites, basalt tuffs, and disperse silicas, as supports for development and subsequent application of palladium(II and copper(II based catalysts for carbon monoxide oxidation. Acid-thermally modified Ukrainian sorbents have been found to be proper for obtaining supported copper-palladium complexes the most catalytically active in the reaction. Application of Ukrainian natural tripolis permitted to avoid the step of acid-thermal modification complicating the technique of catalyst production. As was found, the origin and phase composition of tripolis affect the activity of catalysts supported on them in the reaction of low-temperature Co oxidation. The most active catalyst permitting sanitary purification of air from CO to a level permissible for atmosphere of populated areas have been obtained in the case of insignificantly (thermally or hydrothermally modified tripoli from Konoplianskoe deposit.

    Low-level background shielding of HPGe detectors is used mainly for environmental samples with very low content of radionuclides. National Radiation Protection Institute (SURO) in Prague is equipped with 14 HPGe detectors with relative efficiency up to 150%. The detectors are placed in a room built from materials with low content of natural radionuclides and equipped with a double isolation of the floor against radon. Detectors themselves are placed in lead or steel shielding. Steel shielding with one of these detectors with relative efficiency of 100% was chosen to be rebuilt to achieve lower minimum detectable activity (MDA). Additional lead and copper shielding was built up inside the original steel shielding to reduce the volume of the inner space and filled with nitrogen by means of evaporating liquid nitrogen. The additional lead and copper shielding, consequent reduction of the inner volume and supply of evaporated nitrogen, caused a decrease of the background count and accordingly MDA values as well. The effect of nitrogen evaporation on the net areas of peaks belonging to radon daughters is significant. The enhanced shielding adjustment has the biggest influence in low energy range, what can be seen in collected data. MDA values in energy range from 30 keV to 400 keV decreased to 0.65-0.85 of original value, in energy range from 400 keV to 2 MeV they fell to 0.70-0.97 of original value. (authors)

    The object of the present invention is to enable operators to dismantle shieldings contaminated by radioactivity easily and in a short period of time without danger of radiation exposure. A plurality of introduction pipes are embedded previously to the shielding walls of shielding members which contain a reactor core in a state where both ends of the introduction pipes are in communication with the outside. A wire saw is inserted into the introduction pipes to cut the shieldings upon dismantling. Then, shieldings can be dismantled easily in a short period of time with no radiation exposure to operator's. Further, according to the present invention, since the wire saw can be set easily and a large area can be cut at once, operation efficiency is improved. Further, since remote control is possible, cutting can be conducted in water and complicated places of the reactor. Biting upon starting the wire saw in the introduction pipe is reduced to facilitate startup for the rotation. (I.S.)

    The chemical and isotopic compositions of groundwaters in the crystalline rocks of the Canadian Shield reflect different degrees of rock-water interactions. The chemistry of the shallow, geochemically immature ground waters and especially of the major cations is controlled by local rock compositions, whereby dissolution reactions dominate. Conservative constituents, such as chloride and bromide, however, are not entirely a result of such reactions but appear to be readily added from leachable salts during the initial stages of the geochemical evolution of these waters. Their concentration changes little as major cations increase, until concentrations of Total Dissolved Solids (TDS) reach 3000 to 5000 mg l -1 . The isotopic composition of these shallow waters reflects local, present day precipitations. In contrast to the shallow groundwaters, the isotopic and chemical compositions of the deep, saline waters and brines are determined by extensive, low-temperature rock-water interactions. This is documented in major ion chemistries, 18 O contents and strontium isotopic compositions. These data indicate that the deep brines have been contained in hydrologically isolated pockets. The almost total loss of primary compositions make discussions on the origin of these brines very speculative. However, all brines from across the Canadian Shield have a very similar chemical composition, which probably reflects a common geochemical history. (author)

    A superconducting film shield over a SQUID ring improves the robustness of the SQUID with respect to magnetic noise. Supercurrent in the SQUID magnetometer and the superconducting film shield were simulated. The superconducting film shield reduces the influence of the external magnetic field on the SQUID ring. An HTS SQUID is a high sensitive magnetic sensor. In recent years, the HTS SQUID is widely used in various applications. In some applications, high robustness with respect to magnetic noise is required to realize stable operation at outside of a magnetic shielding room. The target of this paper is a directly coupled HTS dc-SQUID magnetometer. To enhance the robustness of the SQUID magnetometer, use of a superconducting thin film shield has been proposed. The magnetic field directly penetrating the SQUID ring causes the change of the critical current of Josephson junction, and then the SQUID magnetometer transitions into inoperative state. In order to confirm the magnetic shield effect of the superconducting film shield, electromagnetic field simulation with 3D edge finite element method was performed. To simulate the high temperature superconductor, E-J characteristics and c-axis anisotropy are considered. To evaluate the effect of the superconducting film shield, an external magnetic field which is supposed to be a magnetic noise is applied. From the simulation results, the time transition of the magnetic flux penetrating the SQUID ring is investigated and the effect of the superconducting film shield is confirmed. The amplitude of the magnetic flux penetrating the SQUID ring can be reduced to about one-sixth since the superconducting film shield prevents the magnetic noise from directly penetrating the SQUID ring.

  10. Passive magnetic shielding in MRI-Linac systems

    Passive magnetic shielding refers to the use of ferromagnetic materials to redirect magnetic field lines away from vulnerable regions. An application of particular interest to the medical physics community is shielding in MRI systems, especially integrated MRI-linear accelerator (MRI-Linac) systems. In these systems, the goal is not only to minimize the magnetic field in some volume, but also to minimize the impact of the shield on the magnetic fields within the imaging volume of the MRI scanner. In this work, finite element modelling was used to assess the shielding of a side coupled 6 MV linac and resultant heterogeneity induced within the 30 cm diameter of spherical volume (DSV) of a novel 1 Tesla split bore MRI magnet. A number of different shield parameters were investigated; distance between shield and magnet, shield shape, shield thickness, shield length, openings in the shield, number of concentric layers, spacing between each layer, and shield material. Both the in-line and perpendicular MRI-Linac configurations were studied. By modifying the shield shape around the linac from the starting design of an open ended cylinder, the shielding effect was boosted by approximately 70% whilst the impact on the magnet was simultaneously reduced by approximately 10%. Openings in the shield for the RF port and beam exit were substantial sources of field leakage; however it was demonstrated that shielding could be added around these openings to compensate for this leakage. Layering multiple concentric shield shells was highly effective in the perpendicular configuration, but less so for the in-line configuration. Cautious use of high permeability materials such as Mu-metal can greatly increase the shielding performance in some scenarios. In the perpendicular configuration, magnetic shielding was more effective and the impact on the magnet lower compared with the in-line configuration.

    A high resolution sub-regional scale (84 km2) density-dependent, fracture zone network groundwater flow model with hydromechanical coupling and pseudo-permafrost, was developed from a larger 5734 km2 regional scale groundwater flow model of a Canadian Shield setting in fractured crystalline rock. The objective of the work is to illustrate aspects of regional and sub-regional groundwater flow that are relevant to the long-term performance of a hypothetical nuclear fuel repository. The discrete fracture dual continuum numerical model FRAC3DVS-OPG was used for all simulations. A discrete fracture zone network model delineated from surface features was superimposed onto an 789887 element flow domain mesh. Orthogonal fracture faces (between adjacent finite element grid blocks) were used to best represent the irregular discrete fracture zone network. The crystalline rock between these structural discontinuities was assigned properties characteristic of those reported for the Canadian Shield at the Underground Research Laboratory at Pinawa, Manitoba. Interconnectivity of permeable fracture features is an important pathway for the possibly relatively rapid migration of average water particles and subsequent reduction in residence times. The multiple 121000 year North American continental scale paleoclimate simulations are provided by W.R. Peltier using the University of Toronto Glacial Systems Model (UofT GSM). Values of ice sheet normal stress, and proglacial lake depth from the UofT GSM are applied to the sub-regional model as surface boundary conditions, using a freshwater head equivalent to the normal stress imposed by the ice sheet at its base. Permafrost depth is applied as a permeability reduction to both three-dimensional grid blocks and fractures that lie within the time varying permafrost zone. Two different paleoclimate simulations are applied to the sub-regional model to investigate the effect on the depth of glacial meltwater migration into the subsurface. In

    A scintillation counter, particularly for counting gamma ray photons, includes a massive lead radiation shield surrounding a sample-receiving zone. The shield is disassembleable into a plurality of segments to allow facile installation and removal of a photomultiplier tube assembly, the segments being so constructed as to prevent straight-line access of external radiation through the shield into radiation-responsive areas. Provisions are made for accurately aligning the photomultiplier tube with respect to one or more sample-transmitting bores extending through the shield to the sample receiving zone. A sample elevator, used in transporting samples into the zone, is designed to provide a maximum gamma-receiving aspect to maximize the gamma detecting efficiency. (U.S.)

    Full Text Available Here are considered the historical roots of formation and genesis of bunchuks as a part of the whole kleinod complex of Kosh Otamans and Hetmans of the Ukrainian Cossacks. Turkic lexeme «bunchuk» over time has transformed into modern term that is common in Ukrainian culture. Traditionally, the first recorded case of bunchuks’ use by military is associated with the name of the Arab Caliph Abu Bakr and his military battles on the territory of Syria in the 7th century. During the active cross-cultural contacts in the early 13th century, firstly bunchuks became known among the Mongols and later among the Turks. Early Ottomans used them not only as a military sign, but also as a ranking marker of the court official, status present, which raised the social status of a person. From Turks bunchuks were taken by the representatives of the Commonwealth of Poland and at the beginning gave them a meaning of the important symbol of Quarter Army Hetman military power and later, from the middle of the XVII century, of the Polish king. Historical tradition linked the use of bunchuks by Ukrainian Cossacks with the military reforms of Polish monarch Stefan Batory. But modern scientists, studying military history of the Cossacks in the first quarter of the XVII century and using the materials of Polish archives denied this statement and stressed the attention of the Turkish-Tatar vector. For Zaporozhian Cossacks bunchuks were among the attributes of legitimacy or legality of certain actions. In the external design dominated red and black color schemes. National Symbols of early modern Ukrainian state in the middle of the 17th – 18th c., which basis was formed of the attributes of power Zaporozhian Cossacks, recorded bunchuks as personal banners of Hetmans. In order to make the distinction from Zaporozhian Cossacks, Hetmans started using white bunchuks.

    First, a one-dimensional scoping study was performed for the gamma-ray shield of the ELMO Bumpy Torus proof-of-principle device to define appropriate shielding material and determine the required shielding thickness. The dose-equivalent results are analyzed as a function of the radiation-shield thickness for different shielding options. A sensitivity analysis for the pessimistic case is given. The recommended shielding option based on the performance and cost is discussed. Next, a three-dimensional scoping study for the coil shield was performed for four different shielding options to define the heat load for each component and check the compliance with the design criterion of 10 watts maximum heat load per coil from the gamma-ray sources. Also, a detailed biological-dose survey was performed which included: (a) the dose equivalent inside and outside the building, (b) the dose equivalent from the two mazes of the building, and (c) the skyshine contribution to the dose equivalent

    2000-01-01

    Radiation shielding requirements for fusion reactors present different problems than those for fission reactors and accelerators. Fusion devices, particularly tokamak reactors, are complicated by geometry constraints that complicate disposition of fully effective shielding. This paper reviews some of these shielding issues and suggested solutions for optimizing the machine and biological shielding. Radiation transport calculations are essential for predicting and confirming the nuclear performance of the reactor and, as such, must be an essential part of the reactor design process. Development and optimization of reactor components from the first wall and primary shielding to the penetrations and containment shielding must be carried out in a sensible progression. Initial results from one-dimensional transport calculations are used for scoping studies and are followed by detailed two- and three-dimensional analyses to effectively characterize the overall radiation environment. These detail model calculations are essential for accounting for the radiation leakage through ports and other penetrations in the bulk shield. Careful analysis of component activation and radiation damage is cardinal for defining remote handling requirements, in-situ replacement of components, and personnel access at specific locations inside the reactor containment vessel.

    Full Text Available BACKGROUND. Condoms offer the best protection against sexually transmitted infections including HIV. In Ukraine, little research has been conducted to explore possible predictors of condom use at sexual debut. It was hypothesized that the more youth know about possible ways of HIV transmission, the more they are likely to use condoms during the first sexual intercourse.METHODS: Data analyzed in this paper comes from a cross-sectional European School Survey Project on Alcohol and other Drugs conducted among Ukrainian school youth in 2007. The survey involved a total of 5122 students (15–17 year old from all types of secondary schools in 24 oblasts and AR Crimea. Analysis was confined to 1077 students (715 males and 362 females who reported that they have ever had sexual intercourse. Associations were assessed in bivariate analysis using Chi-square test and later using binary logistic regression analysis in order to identify the significant predictors after controlling for other variables.RESULTS: Among the sexually experienced students, more than 70% had used condoms during first sexual intercourse. The results from the logistic regression analysis revealed that the age at first sexual intercourse, HIV awareness, alcohol consumption and family characteristics were significant predictors of condom use at first sexual intercourse among the Ukrainian schoolchildren. Students who had first sex at the age from 14 to 16 years were more likely to use condom at their first sexual intercourse than those with sexual debut before 14 years old (odds ratios 2,4; 2,1; and 3,3, respectively. Moreover, those students who were aware that using condom may protect against getting HIV were more likely (OR 2,1 to use condom at first sex.CONCLUSIONS: The results indicate the necessity of providing educational programs which aim to raise the level of awareness about HIV among Ukrainian youth.

    Full Text Available The significant increase in the number of new food products means consumers have the opportunity to choose from among a wide range of innovative foods, which bring a variety of benefits to consumption, but can also, for some, raise uncertainty, opposition and suspicion. The article reviews the literature on innovative food products and their acceptance by consumers. The results of own research on the purchase motives and barriers to consumption of such products are presented in the context of theoretical considerations. The study is presented in relation to the issue of consumer innovativeness as a determinant affecting the approval or rejection of new products. The respondents’ degree of innovativeness was evaluated according to Rogers’ concept and the impact of this variable on the respondents motives of to purchase innovative products. For the comparative analysis of Polish and Ukrainian consumers’ behaviour on the innovative food products market, international research was conducted in 2015 on a sample of 340 Polish and 255 Ukrainian respondents (595 respondents in total. The results clearly show consumer types differing from the Rogers distribution, as well as differences between Polish and Ukrainian consumers’ appetite for innovation. Analysis of the literature and the research results together indicate that the motives and barriers to consuming innovative food products come down to features of the innovation (including price, functionality, healthiness, convenient packaging, taste, consumer characteristics (neophilia, neophobia, innovativeness and environmental characteristics (trends in consumption, marketing and social communication. Those consumers who are innovators play an important role in shaping the positive attitudes of buyers in relation to innovative food products. Products possessing attributes consumers consider to be essential may also help in the desire to adopt innovation. Basing on the research results certain

    The radiation transport methodology comparing the calculated reactions and dose rates for neutrons and gama-rays, with experimental measurements obtained on iron shield, irradiated in the YAYOI reactor is evaluated. The ENDF/B-IV and VITAMIN-C libraries and the AMPX-II modular system, for cross sections generation collapsed by the ANISN code were used. The transport calculations were made using the DOT 3.5 code, adjusting the boundary iron shield source spectrum to the reactions and dose rates, measured at the beginning of shield. The neutron and gamma ray distributions calculated on the iron shield presented reasonable agreement with experimental measurements. An experimental arrangement using the IEA-R1 reactor to determine a shielding benchmark is proposed. (Author) [pt

    Shield volcanoes are described as low-angle edifices built primarily by the accumulation of successive lava flows. This generic view of shield volcano morphology is based on a limited number of monogenetic shields from Iceland and Mexico, and a small set of large oceanic islands (Hawaii, Galápagos). Here, the morphometry of 158 monogenetic and polygenetic shield volcanoes is analyzed quantitatively from 90-meter resolution SRTM DEMs using the MORVOLC algorithm. An additional set of 24 lava-dominated 'shield-like' volcanoes, considered so far as stratovolcanoes, are documented for comparison. Results show that there is a large variation in shield size (volumes from 0.1 to > 1000 km3), profile shape (height/basal width (H/WB) ratios mostly from 0.01 to 0.1), flank slope gradients (average slopes mostly from 1° to 15°), elongation and summit truncation. Although there is no clear-cut morphometric difference between shield volcanoes and stratovolcanoes, an approximate threshold can be drawn at 12° average slope and 0.10 H/WB ratio. Principal component analysis of the obtained database enables to identify four key morphometric descriptors: size, steepness, plan shape and truncation. Hierarchical cluster analysis of these descriptors results in 12 end-member shield types, with intermediate cases defining a continuum of morphologies. The shield types can be linked in terms of growth stages and shape evolution, related to (1) magma composition and rheology, effusion rate and lava/pyroclast ratio, which will condition edifice steepness; (2) spatial distribution of vents, in turn related to the magmatic feeding system and the tectonic framework, which will control edifice plan shape; and (3) caldera formation, which will condition edifice truncation.

    During refueling of a nuclear power plant, the reactor upper internals must be removed from the reactor vessel to permit transfer of the fuel. The upper internals are stored in the flooded reactor cavity. Refueling personnel working in containment at a number of nuclear stations typically receive radiation exposure from a portion of the highly contaminated upper intervals package which extends above the normal water level of the refueling pool. This same issue exists with reactor lower internals withdrawn for inservice inspection activities. One solution to this problem is to provide adequate shielding of the unimmersed portion. The use of lead sheets or blankets for shielding of the protruding components would be time consuming and require more effort for installation since the shielding mass would need to be transported to a support structure over the refueling pool. A preferable approach is to use the existing shielding mass of the refueling pool water. A method of shielding was devised which would use a vacuum pump to draw refueling pool water into an inverted canister suspended over the upper internals to provide shielding from the normally exposed components. During the Spring 1993 refueling of Indian Point 2 (IP2), a prototype shield device was demonstrated. This shield consists of a cylindrical tank open at the bottom that is suspended over the refueling pool with I-beams. The lower lip of the tank is two feet below normal pool level. After installation, the air width of the natural shielding provided by the existing pool water. This paper describes the design, development, testing and demonstration of the prototype device.

    The third shielding expert conference was convened in Paris in Oct. 1975 for exchanging informations about the sensitivity evaluation of nuclear data in shielding calculation and integral bench mark experiment. The requirements about nuclear data presented at present from the field of nuclear design do not reflect sufficiently the requirements of shielding design, therefore it was the object to gather the requirements about nuclear data from the field of shielding. The nuclides used for shielding are numerous, and the nuclear data on these isotopes are required. Some of them cannot be ignored as the source of secondary γ-ray or in view of the radioactivation of materials. The requirements for the nuclear data of neutrons in the field of shielding are those concerning the reaction cross sections producing secondary γ-ray, the reaction cross sections including the production of secondary neutrons, elastic scattering cross sections, and total cross sections. The topics in the Paris conference about neutron shielding data are described, such as the methodology of sensitivity evaluation, the standardization of group constant libraries, the bench mark experiment on iron and sodium, and the cross section of γ-ray production. In the shielding of nuclear fission reactors, the γ-ray production owing to nuclear fission reaction is also important. In (d, t) fusion reactors, high energy neutrons are generated, and high energy γ-ray is emitted through giant E1 resonance. (Kako, I.)

    Research highlights: → We investigated the problem of optimization of a multi-layered metallic shield. → The maximum ballistic limit velocity is a criterion of optimization. → The sequence of materials and the thicknesses of layers in the shield are varied. → The general problem is reduced to the problem of Geometric Programming. → Analytical solutions are obtained for two- and three-layered shields. - Abstract: We investigate the problem of optimization of multi-layered metallic shield whereby the goal is to determine the sequence of materials and the thicknesses of the layers that provide the maximum ballistic limit velocity of the shield. Optimization is performed under the following constraints: fixed areal density of the shield, the upper bound on the total thickness of the shield and the bounds on the thicknesses of the plates manufactured from every material. The problem is reduced to the problem of Geometric Programming which can be solved numerically using known methods. For the most interesting in practice cases of two-layered and three-layered shields the solution is obtained in the explicit analytical form.

    In shielding calculation of radiological facilities, several parameters are required, such as occupancy, use factor, number of patients, source-barrier distance, area type (controlled and uncontrolled), radiation (primary or secondary) and material used in the barrier. The shielding design optimization requires a review of several options about the physical facility design and, mainly, the achievement of the best cost-benefit relationship for the shielding material. To facilitate the development of this kind of design, a program to calculate the shielding in diagnostic radiology was implemented, based on data and limits established by National Council on Radiation Protection and Measurements (NCRP) 147 and SVS-MS 453/98. The program was developed in C⌗ language, and presents a graphical interface for user data input and reporting capabilities. The module initially implemented, called SHIELD 1.0, refers to calculating barriers for conventional X-ray rooms. The program validation was performed by the comparison with the results of examples of shielding calculations presented in NCRP 147.

    Full Text Available Passive radiation shielding is one strategy to mitigate the problem of space radiation exposure. While space vehicles are constructed largely of aluminum, polyethylene has been demonstrated to have superior shielding characteristics for both galactic cosmic rays and solar particle events due to the high hydrogen content. A method to calculate the shielding effectiveness of a material relative to reference material from Bragg peak measurements performed using energetic heavy charged particles is described. Using accelerated alpha particles at the National Aeronautics and Space Administration Space Radiation Laboratory at Brookhaven National Laboratory, the method is applied to sample tiles from the Heat Melt Compactor, which were created by melting material from a simulated astronaut waste stream, consisting of materials such as trash and unconsumed food. The shielding effectiveness calculated from measurements of the Heat Melt Compactor sample tiles is about 10% less than the shielding effectiveness of polyethylene. Shielding material produced from the astronaut waste stream in the form of Heat Melt Compactor tiles is therefore found to be an attractive solution for protection against space radiation.

    To reduce the radiation dose to the thyroid that is affected to scattered radiation, the shield was used. And we evaluated the shielding effect for the thyroid during whole brain radiation therapy. To measure the dose of the thyroid, 300cGy were delivered to the phantom using a linear accelerator(Clinac iX VARIAN, USA.)in the way of the 6MV X-ray in bilateral. To measure the entrance surface dose of the thyroid, five glass dosimeters were placed in the 10th slice's surface of the phantom with a 1.5 cm interval. The average values were calculated by measured values in five times each, using bismuth shield, 0.5 mmPb shield, self-made 1.0 mmPb shield and unshield. In the same location, to measure the depth dose of the thyroid, five glass dosimeters were placed in the 10th slice by 2.5 cm depth of the phantom with a 1.5 cm interval. The average values were calculated by measured values in five times each, using bismuth shield, 0.5 mmPb shield, self-made 1.0 mmPb shield and unshield. Entrance surface dose of the thyroid were respectively 44.89 mGy at the unshield, 36.03 mGy at the bismuth shield, 31.03 mGy at the 0.5 mmPb shield and 23.21 mGy at a self-made 1.0 mmPb shield. In addition, the depth dose of the thyroid were respectively 36.10 mGy at the unshield, 34.52 mGy at the bismuth shield, 32.28 mGy at the 0.5 mmPb shield and 25.50 mGy at a self-made 1.0 mmPb shield. The thyroid was affected by the secondary scattering dose and leakage dose outside of the radiation field during whole brain radiation therapy. When using a shield in the thyroid, the depth dose of thyroid showed 11-30% reduction effect and the surface dose of thyroid showed 20-48% reduction effect. Therefore, by using the thyroid shield, it is considered to effectively protect the thyroid and can perform the treatment.

    Full Text Available After a period of continuous troubles that Ukraine has witnessed over a period of its history, the issue of national identity today appears to be more acute than ever before. It is explained by various reasons that are not under consideration in this research. However, the notion of national identity, its factors and modern perspectives are of a great scientific importance. Amid the principles of identity there is one that refers to the existential feeling of belonging and the desire to unite in factions with those who share similar interests. Besides, national identity is viewed as the factor that affects the preservation and development of the Ukrainian nation. The paper presents the research with aim to define the national identity and its integral parts that are essential for identity preservation. National identity is understood as a collective structure that illustrates how similar or different the elements of society are. Five factors of national identity that are considered in the paper are the collective identification that is realized in religious and cultural beliefs, common history and the feeling of belonging, active social life, which is illustrated by one’s participation in cultural activities, geographical belonging and national character that is a set of cultural believes followed by the representatives of a particular national group. The literary work of Lesia Bohuslavets, a Ukrainian immigrant who lives in Australia, is under consideration in this paper. She was defined as a writer under analysis as she is viewed as an example of those conscientious Ukrainians who feel responsible for cultural and national preservation. The literary work “My Australian kuma” of Lesia Bohuslavets was analysed by means of content analysis which is a statistic means of language evaluation. The result of content analysis proved that national character and active social life categories were marked with the highest variables. It means that

    In order to develop shielding technology for high energy radiation production facility, references and data for high energy neutron shielding are searched and collected, and calculations to obtain the characteristics of neutron shield materials are performed. For the evaluation of characteristics of neutron shield material, it is chosen not only general shield materials such as concrete, polyethylene, etc., but also KAERI developed neutron shields of High Density PolyEthylene (HDPE) mixed with boron compound (B 2 O 3 , H 2 BO 3 , Borax). Neutron attenuation coefficients for these materials are obtained for later use in shielding design. The effect of source shape and source angular distribution on the shielding characteristics for several shield materials is examined. This effect can contribute to create shielding concept in case of no detail source information. It is also evaluated the effect of the arrangement of shield materials using current shield materials. With these results, conceptual shielding design for PET cyclotron is performed. The shielding composite using HDPE and concrete is selected to meet the target dose rate outside the composite, and the dose evaluation is performed by configuring the facility room conceptually. From the result, the proper shield configuration for this PET cyclotron is proposed

    The search for the electric dipole moment of the neutron requires the ambient magnetic field to be on the pT scale which is accomplished with large magnetic shielding rooms. These rooms are fitted with large mu-metal sheets to allow for passive cancellation of background magnetic fields. Active shielding technology cannot uniformly cancel background magnetic fields. These issues can be remedied by combining the methods into a hybrid system. The design used is composed of panels that have an active layer of cancellation between two sheets of mu-metal. The panels form a cube and draw in magnetic fields perpendicular to the surface which can then be reduced using active shielding. This work is supported by the Department of Energy under Contract DE-SC0008107.

    To investigate available shielding methods in an effort to further awareness and understanding of existing preventive measures related to patient exposure in computed tomography (CT) scanning. Searches were conducted to locate literature discussing the effectiveness of commercially available shields. Literature containing information regarding breast, gonad, eye and thyroid shielding was identified. Because of rapidly advancing technology, the selection of articles was limited to those published within the past 5 years. The selected studies were examined using the following topics as guidelines: the effectiveness of the shield (percentage of dose reduction), the shield's effect on image quality, arguments for or against its use (including practicality) and overall recommendation for its use in clinical practice. Only a limited number of studies have been performed on the use of shields for the eyes, thyroid and gonads, but the evidence shows an overall benefit to their use. Breast shielding has been the most studied shielding method, with consistent agreement throughout the literature on its effectiveness at reducing radiation dose. The effect of shielding on image quality was not remarkable in a majority of studies. Although it is noted that more studies need to be conducted regarding the impact on image quality, the currently published literature stresses the importance of shielding in reducing dose. Commercially available shields for the breast, thyroid, eyes and gonads should be implemented in clinical practice. Further research is needed to ascertain the prevalence of shielding in the clinical setting.

    Radiation shielding cloth having radiation shielding layers comprising a composition of inorganic powder of high specific gravity and rubber are excellentin flexibility and comfortable to put on. However, since they are heavy in the weight, operators are tired upon putting them for a long time. In view of the above, the radiation ray shielding layers are prepared by calendering sheets obtained by preliminary molding of the composition to set the variation of the thickness within a range of +15% to -0% of prescribed thickness. Since the composition of inorganic powder at high specific gravity and rubber used for radiation ray shielding comprises a great amount of inorganic powder at high specific gravity blended therein, it is generally poor in fabricability. Therefor, it is difficult to attain fine control for the sheet thickness by merely molding a composition block at once. Then, the composition is at first preliminarily molded into a sheet-like shape which is somewhat thickener than the final thickness and then finished by calendering, by which the thickness can be reduced in average as compared with conventional products while keeping the prescribed thickness and reducing the weight reduce by so much.

    It was found that a glass composition comprising, as essential ingredients, SiO 2 , PbO, Gd 2 O 3 and alkali metal oxides can provide a shielding performance against electromagnetic waves, charged particles and neutrons. The present invention provides radiation shielding glass containing at least from 16 to 46wt% of SiO 2 , from 47 to 75wt% of PbO, from 1 to 10wt% of Gd 2 O 3 , from 0 to 3wt% of Li 2 O, from 0 to 7wt% of Na 2 O, from 0 to 7wt% of K 2 O provided that Li 2 O + Na 2 O + K 2 O is from 1 to 10wt%, B 2 O 3 is from 0 to 10wt%, CeO 2 is from 0 to 3wt%, As 2 O 3 is from 0 to 1wt% and Sb 2 O 3 is from 0 to 1wt%. Since the glass can shield electromagnetic waves, charged particles and neutrons simultaneously, radiation shielding windows can be designed and manufactured at a reduced thickness and by less constitutional numbers in a circumstance where they are present altogether.

    Shielding modification design of the N.S. Mutsu was performed for reducing the radiation doses outside the primary and the secondary shields by providing shields for neutrons streaming through the air gap between the pressure vessel and the primary shield. This was accomplished by replacing parts of the shields and adding new shields in the upper and lower sections of both primary and secondary shields, and also replacing the thermal insulator in the gap. The shielding design calculations were made using one- and two-dimensional discrete ordinates codes and also a point kernel code. Special attention was paid to the calculations of, (1) the neutrons streaming through the gap between the pressure vessel and the primary shield, (2) the radiations transmitted through the radial shield of the core in the primary shield, (3) the radiations transmitted through the upper and lower sections of the secondary shield, and (4) the dose rate equivalent in the accommodation area. Their calculational accuracies were estimated by analyzing various experiments. To support the modification, a variety of experiments and tests were carried out, which were material tests, cooling test of the primary shield, mechanical strength test of the double bottom, trial fabrication tests of new shields, performance degradation test of heavy concrete and duct streaming experiment in the secondary shield.

    This patent describes a method of limiting the movement of a thermal shield of a nuclear reactor. It comprises: machining at least four (4) pockets in upper portions of a thermal shield circumferentially about a core barrel of a nuclear reactor to receive key-wave inserts; tapping bolt holes in the pockets of the thermal shield to receive bolts; positioning key-wave inserts into the pockets of the thermal shield to be bolted in place with the bolt holes; machining dowel holes at least partially through the positioned key-way inserts and the thermal shield to receive dowel pins; positioning dowel pins in the dowel holes in the key-way insert and thermal shield to tangentially restrain movement of the thermal shield relative to the core barrel; sliding limiter keys into the key-way inserts and bolting the limiter keys to the core barrel to tangentially restrain movement of the thermal shield relative and the core barrel while allowing radial and axial movement of the thermal shield relative to the core barrel; machining dowel holes through the limiter key and at least partially through the core barrel to receive dowel pins; positioning dowel pins in the dowel holes in the limiter key and core barrel to restrain tangential movement of the thermal shield relative to the core barrel of the nuclear reactor

    Evaluation of penetration and discontinuity shielding is necessary to meet 10CFR20 regulations for ensuring personnel exposures are as low as reasonably achievable (ALARA). Historically, those shielding evaluations have been done to some degree on all projects. However, many early plants used conservative methods due to lack of an economical computer code, resulting in costly penetration shielding programs. With the increased industry interest in cost effectively reducing personnel exposures to meet ALARA regulations and with the development of the CYLSEC gamma transport computer code at Bechtel, a comprehensive effort was initiated to reduce penetration and discontinuity shielding but still provide a prudent degree of protection for plant personnel from radiation streaming. This effort was more comprehensive than previous programs due to advances in shielding analysis technology and increased interest in controlling project costs while maintaining personnel exposures ALARA. Methodology and resulting cost savings are discussed

    Many shieldings have been designed under the criteria of 'Maximum dose rates of project'. It has created the paradigm of those 'low dose rates', for the one which not few specialists would consider unacceptable levels of dose rate superior to the units of μSv.h -1 , independently of the exposure times. At the present time numerous shieldings are being designed considering dose restrictions in real times of exposure. After these new shieldings, the dose rates could be notably superior to those after traditional shieldings, without it implies inadequate designs or constructive errors. In the work significant differences in levels of dose rates and thickness of shieldings estimated by both methods for some typical facilities. It was concluded that the use of real times of exposure is more adequate for the optimization of the Radiological Protection, although this method demands bigger care in its application. (Author)

    Recently, the utilization of accelerators has increased rapidly, and the increase of accelerating energy and beam intensity is also remarkable. The studies on accelerator shielding have become important, because the amount of radiation emitted from accelerators increased, the regulation of the dose of environmental radiation was tightened, and the cost of constructing shielding rose. As the plans of constructing large accelerators have been made successively, the survey on the present state and the problems of the studies on accelerator shielding was carried out. Accelerators are classified into electron accelerators and proton accelerators in view of the studies on shielding. In order to start the studies on accelerator shielding, first, the preparation of the cross section data is indispensable. The cross sections for generating Bremsstrahlung, photonuclear reactions generating neutrons, generation of neutrons by hadrons, nuclear reaction of neutrons and generation of gamma-ray by hadrons are described. The generation of neutrons and gamma-ray as the problems of thick targets is explained. The shielding problems are complex and diversified, but in this paper, the studies on the shielding, by which basic data are obtainable, are taken up, such as beam damping and side wall shielding. As for residual radioactivity, main nuclides and the difference of residual radioactivity according to substances have been studied. (J.P.N.)

    1989-01-01

    Neutrons produced by 800-MeV proton reactions at the Los Alamos Neutron Scattering Center spallation neutron source cause a variety of challenging shielding problems. We identify several characteristics distinctly different from reactor shielding and compute the dose attenuation through an infinite slab/shield composed of iron (100 cm) and borated polyethylene (15 cm). Our calculations show that (for an incident spallation spectrum characteristic of neutrons leaking from a tungsten target at 90/degree/) the dose through the shield is a complex mixture of neutrons and gamma rays. High-energy (> 20 MeV) neutron production from the target is ≅5% of the total, yet causes ≅68% of the dose at the shield surface. Primary low-energy (< 20 MeV) neutrons from the target contribute negligibly (≅0.5%) to the dose at the shield surface yet cause gamma rays, which contribute ≅31% to the total dose at the shield surface. Low-energy neutrons from spallation reactions behave similarly to neutrons with a fission spectrum distribution. 6 refs., 8 figs., 1 tab

    Organic materials, inorganic materials or metals having excellent radiation shielding performance are impregnated into expanded metal materials, such as Al, Cu or Mg, having high heat conductivity. Further, the porosity of the expanded metals and combination of the expanded metals and the materials to be impregnated are changed depending on the purpose. Further, a plurality of shielding materials are impregnated into the expanded metal of the same kind, to constitute shielding materials. In such shielding materials, impregnated materials provide shielding performance against radiation rays such as neutrons and gamma rays, the expanded metals provide heat removing performance respectively and they act as shielding materials having heat removing performance as a whole. Accordingly, problems of non-informity and discontinuity in the prior art can be dissolved be provide materials having flexibility in view of fabrication work. (T.M.)

  3. Gonadal Shielding in Radiography: A Best Practice?

    To investigate radiation dose to phantom testes with and without shielding. A male anthropomorphic pelvis phantom was imaged with thermoluminescent dosimeters (TLDs) placed in the right and left detector holes corresponding to the testes. Ten exposures were made of the pelvis with and without shielding. The exposed TLDs were packaged securely and mailed to the University of Wisconsin Calibration Laboratory for reading and analysis. A t test was calculated for the 2 exposure groups (no shield and shielded) and found to be significant, F = 8.306, P shield was used during pelvic imaging. Using a flat contact shield during imaging of the adult male pelvis significantly reduces radiation dose to the testes. Regardless of the contradictions in the literature on gonadal shielding, the routine practice of shielding adult male gonads during radiographic imaging of the pelvis is a best practice. © 2016 American Society of Radiologic Technologists.

  4. Estimating ISABELLE shielding requirements

    Stevens, A.J.; Thorndike, A.M.

    1976-01-01

    Estimates were made of the shielding thicknesses required at various points around the ISABELLE ring. Both hadron and muon requirements are considered. Radiation levels at the outside of the shield and at the BNL site boundary are kept at or below 1000 mrem per year and 5 mrem/year respectively. Muon requirements are based on the Wang formula for pion spectra, and the hadron requirements on the hadron cascade program CYLKAZ of Ranft. A muon shield thickness of 77 meters of sand is indicated outside the ring in one area, and hadron shields equivalent to from 2.7 to 5.6 meters in thickness of sand above the ring. The suggested safety allowance would increase these values to 86 meters and 4.0 to 7.2 meters respectively. There are many uncertainties in such estimates, but these last figures are considered to be rather conservative

    The George Kuzmych Training Center (GKTC) was created at the Kyiv Institute for Nuclear Research as a result of collaborative efforts between the United States and Ukraine in 1998. Later the European Commission (EC) and Sweden joined the USA supporting MC&A aspects of the GKTC activity. The GKTC was designated by the Ukrainian Government to provide the MPC&A training and methodological assistance to nuclear facilities and nuclear specialists. In order to increase the efficiency of State MC&A system an essential number of new regulations, norms and rules was developed demanding regular and more intensive MC&A experts training from the Regulatory Body of Ukraine and all nuclear facilities. For this purpose ten training courses were developed by the GKTC under the EC contract taking into account both specifics of Ukrainian nuclear facilities and expertise level of their personnel. Along with the NDA training laboratory created with the US DOE financial support and methodological assistance in 2003, a new surveillance and containment laboratory was created under the EC contract and with US DOE financial support as well. Moreover, under the EC contract the laboratory was equipped with the state-of-the-art and most advanced means of surveillance and containment strengthening even more the GKTC training opportunities. As a result, the MC&A experts from all nuclear facilities and Regulatory Body of Ukraine can regularly be trained practically on all MC&A issues. This paper briefly describes the practical efforts applied to improve Ukrainian MC&A systems both at the State and facility levels and real results on the way to develop the National System for MC&A regular training at the GKTC, problems encountered and their solution, comments, suggestions and recommendations for the future activity to promote and improve the nuclear security culture in Ukraine.

    Purpose: To increase the shielding capacity of the radiation shielding material having an abundant flexibility. Constitution: A mat consisting of a lead or lead alloy fibrous material is covered with a cloth, and the two are made integral by sewing in a kilted fashion by using a yarn. Thereafter, the system is covered with a gas-tight film or sheet. The shielding material obtained in this way has, in addition to the above merits, advantages in that (1) it is free from restoration due to elasticity so that it can readily seal contaminants, (2) it can be used in a state consisting of a number of overlapped layers, (3) it fits the shoulder well and is readily portable and (4) it permits attachment of fasteners or the like.

    1983-01-01

    The protective effect in the thyroid region from different types of radiation shieldings at intraoral radiography has been studied as well as the reduction of the absorbed dose to the sternal and the gonadal regions. The shieldings tested were five different types of leaded aprons, of which three had an attached leaded collar and the other two were used in combination with separate soft leaded collars. Furthermore one of the soft leaded collars and an unflexible horizontal leaded shield were tested separately. Two dental x-ray machines of 60 and 65 kVp with rectangular and circular tube collimators were used. The exposure time corresponded to speed group E film. The absorbed doses were measured with two ionization chambers. No significant difference in the protective effect in the thyroid gland could be found between the different types of radiation shieldings. There was a dose reduction by approximately a factor of 2 to the thyroid region down to 0.08 mGy per full survey using parallelling technique, and below 0.001 mGy per single bitewing exposure. The shieldings reduced the thyroid dose using bisecting-angle technique by a factor of 5 down to 0.15 mGy per full survey (20 exposures). In the sternal region the combinations of apron and collar reduced the absorbed dose from a full survey to below 2 μGy compared with 18 μGy (parallelling) and 31 μGy (biscting-angle) without any shielding. With the horizontal leaded shield a reduction by a factor of 6 was obtained but no significant sternal dose reduction could be detected from the soft collar alone. The gonadal dose could be reduced by a factor of 10 with the horizontal leaded shield, parallelling technique and circular collimator. Using leaded aprons the gonadal dose was approximately one per cent of the dose without any shielding, i.e. below 0.01 μGy per single intraoral exposure. (Authors)

    This article summarizes the results of 30 y of follow-up of cancer and noncancer effects in Ukrainian cleanup workers after the Chornobyl accident. The number of power plant employees and first responders with acute radiation syndrome under follow-up by the National Research Center for Radiation Medicine decreased from 179 in 1986-1991 to 105 in 2011-2015. Cancers and leukemia (19) and cardiovascular diseases (21) were the main causes of deaths among acute radiation syndrome survivors (54) during the postaccident period. Increased radiation risks of leukemia in the Ukrainian cohort of 110,645 cleanup workers exposed to low doses are comparable to those among survivors of the atomic bomb explosions in Japan in 1945. Additionally, an excess of chronic lymphocytic leukemia was demonstrated in the cleanup workers cohort for 26 y after the exposure. A significant excess of multiple myeloma incidence [standardized incidence rate (SIR) 1.61 %, 95% confidence interval (CI) 1.01-2.21], thyroid cancer (SIR 4.18, 95% CI 3.76-4.59), female breast cancer (SIR 1.57 CI 1.40-1.73), and all cancers combined (SIR 1.07; 95% CI 1.05-1.09) was registered. High prevalence was demonstrated for cardio- and cerebrovascular diseases and mental health changes. However, the reasons for the increases require further investigation. To monitor other possible late effects of radiation exposure in Chornobyl cleanup workers, analytical cohort and case-control studies need to include cardiovascular pathology, specifically types of potentially radiogenic cancers using a molecular epidemiology approach. Possible effects for further study include increased rates of thyroid, breast, and lung cancers and multiple myeloma; reduction of radiation risks of leukemia to population levels; and increased morbidity and mortality of cleanup workers from cardio- and cerebrovascular pathology.

    The ability to cool superconductors with liquid nitrogen instead of liquid helium has opened the door to a wide range of research. The well known Meissner effect, which states superconductors are perfectly diamagnetic, suggests shielding applications. One of the drawbacks to the new ceramic superconductors is the brittleness of the finished material. Because of this drawback, any application which required flexibility (e.g., wire and cable) would be impractical. Therefore, this paper presents the results of a preliminary investigation into the shielding effectiveness of YBa 2 Cu 3 O/sub 7-x/ both as a composite and as a monolithic material. Shielding effectiveness was measured using two separate test methods. One tested the magnetic (near field) shielding, and the other tested the electromagnetic (far field) shielding. No shielding was seen in the near field measurements on the composite samples, and only one heavily loaded sample showed some shielding in the far field. The monolithic samples showed a large amount of magnetic shielding. 5 refs., 5 figs

    Prevention of electromagnetic interference (EMI), or ''noise pickup,'' is an important design aspect in large detectors in accelerator environments. Shielding effectiveness as a function of shield thickness and conductivity vs the type and frequency of the interference field is described. Noise induced in transmission lines by ground loop driven currents in the shield is evaluated and the importance of low shield resistance is emphasized. Some measures for prevention of ground loops and isolation of detector-readout systems are discussed

    1984-01-01

    The reduction of gonadal dose by shielding of the gonads was investigated for a Somatom 2 using an anthropomorphic phantom. For small distances from the slice examined the gonadal dose results from intracorporal secondary radiation and is only insignificantly reduced by shielding. For greater distances shielding is relatively more effective, the gonadal dose however is small because of the approximately exponential decay. Shielding of the gonads therefore does not seem adequate for the reduction of gonadal dose. From dose measurements in cylinder phantoms of several diameters it appears that no different results would be obtained for children and young adults. An effective reduction of gonadal dose is only possible with lead capsules for males. (author)

    2006-09-15

    The paper deals with the values of risk related to environmental pollution with radionuclides from the main sources located both on the territory of Ukraine and outside, which affect the Ukrainian population, in the context of long-range outlook. Ratios of risk for stochastic effects occurrence are given per unit of individual or collective dose, as well as for occurrence of fatal cancer, non-fatal cancer or serious hereditary effects. Besides, the paper mentions not only the impact of ionizing radiation, but severe population stress as well, which in certain regions turns into radiophobia. It is shown that for essential decrease of radiation risk in Ukraine, global problems should be solved, first of all, at the governmental level. Whereas a number of issues connected with the Chernobyl catastrophe are at least partially solved, the problems concerning the effects of radon and other radiation-dangerous factors are still to be tackled.

    Recent investigations based on conventional chromosome aberration data by the RERF suggest that the DS86 doses received by many Nagasaki factory workers may have been overestimated by as much as 40% relative to those for other survivors in Japanese-type houses and other shielding configurations (Kodama et al. 2001). Since the factory workers represent about 25% of the Nagasaki survivors with DS86 doses in excess of 0.5 Gy (50 rad), systematic errors in their dose estimates can have a major impact on the risk coefficients from RERF studies. The factory worker doses may have been overestimated for a number of reasons. The calculation techniques, including the factory building modeling, weapon source spectra and cross-section data used in the DS86 shielding calculations were not detailed enough to replicate actual conditions. The models used did not take into account local shielding provided by machinery, tools, and the internal structure in the buildings. In addition, changes in the disposition of shielding following collapse of the building by the blast wave were not considered. The location of large factory complexes may be uncertain, causing large numbers of factory survivors, correctly located relative to each other, to be uniformly too close to the hypocenter. Any or all of these reasons are sufficient to result in an overestimate of the factory worker doses. During the DS02 studies, factory worker doses have been reassessed by more carefully modeling the factory buildings, incorporating improved radiation transport methods and cross-section data and using the most recent bomb leakage spectra (Chapter 2). Two-dimensional discrete ordinates calculations were carried out initially to estimate the effects of workbenches and tools on worker doses to determine if the inclusion of these components would, in fact, reduce the dose by amounts consistent with the RERF observations (Kodama et al. 2001).

    Today, reactor dosimetry and shielding have wide areas of overlap as concerns both problems and methods. Increased interchange of results and know-how would benefit both. The areas of common interest include calculational methods, sensitivity studies, theoretical and experimental benchmarks, cross sections and other nuclear data, multigroup libraries and procedures for their adjustment, experimental techniques and damage functions. This paper reviews the state-of-the-art and the latest development in each of these areas as far as shielding is concerned, and suggests a number of interactions that could be profitable for reactor dosimetry. Among them, re-evaluation of the potentialities of calculational methods (in view of the recent developments) in predicting radiation environments of interest; the application of sensitivity analysis to dosimetry problems; a common effort in the field of theoretical benchmarks; the use of the shielding one-material propagation experiments as reference spectra for detector cross sections; common standardization of the detector nuclear data used in both fields; the setting up of a common (or compatible) multigroup structure and library applicable to shielding, dosimetry and core physics; the exchange of information and experience in the fields of cross section errors, correlations and adjustment; and the intercomparison of experimental techniques

    To assess effects of off-centering, automatic exposure control, and padding on attenuation values, noise, and radiation dose when using in-plane bismuth-based shields for CT scanning. A 30 cm anthropomorphic chest phantom was scanned on a 64-multidetector CT, with the center of the phantom aligned to the gantry isocenter. Scanning was repeated after placing a bismuth breast shield on the anterior surface with no gap and with 1, 2, and 6 cm of padding between the shield and the phantom surface. The 'shielded' phantom was also scanned with combined modulation and off-centering of the phantom at 2 cm, 4 cm and 6 cm below the gantry isocenter. CT numbers, noise, and surface radiation dose were measured. The data were analyzed using an analysis of variance. The in-plane shield was not associated with any significant increment for the surface dose or CT dose index volume, which was achieved by comparing the radiation dose measured by combined modulation technique to the fixed mAs (p > 0.05). Irrespective of the gap or the surface CT numbers, surface noise increased to a larger extent compared to Hounsfield unit (HU) (0-6 cm, 26-55%) and noise (0-6 cm, 30-40%) in the center. With off-centering, in-plane shielding devices are associated with less dose savings, although dose reduction was still higher than in the absence of shielding (0 cm off-center, 90% dose reduction; 2 cm, 61%) (p < 0.0001). Streak artifacts were noted at 0 cm and 1 cm gaps but not at 2 cm and 6 cm gaps of shielding to the surface distances. In-plane shields are associated with greater image noise, artificially increased attenuation values, and streak artifacts. However, shields reduce radiation dose regardless of the extent of off-centering. Automatic exposure control did not increase radiation dose when using a shield.

    The duct shield from streaming D-T neutrons has been designed for the ITER pressure suppression system. Streaming calculations are performed with the DUCT-III code for the region from the inlet of the pressure relief line to the rupture disk. Next, the neutron permeation through the shield is studied by Monte Carlo calculations with the MCNP code. It is found that 0.15 m thick iron shield is enough to suppress the permeating component from the outside. In addition, it is suggested that the volume of the shield can be reduced by about 30% if the optimized iron shield structure having localized thickness across intense permeation paths is employed to shield the pressure suppression line.

    Low fields and low frequency shielding properties of YBCO magnetic shields are measured at 77 K. They compare favourably with shielding properties of mumetal shields. Therefore high-T{sub c} superconducting magnetic shields can already be used to shield small volumes. The case of magnetic shields for large volumes is also discussed. 3 refs; 6 figs; 4 tabs.

    General approaches to the solution of problems on the nuclear power plant radiation shield optimization are considered. The requirements to the shield parameters are formulated in a form of restrictions on a number of functionals, determined by the solution of γ quantum and neutron transport equations or dimensional and weight characteristics of shield components. Functional determined by weight-dimensional parameters (shield cost, mass and thickness) and functionals, determined by radiation fields (equivalent dose rate, produced by neutrons and γ quanta, activation functional, radiation functional, heat flux, integral heat flux in a particular part of the shield volume, total energy flux through a particular shield surface are considered. The following methods of numerical solution of simplified optimization problems are discussed: semiempirical methods using radiation transport physical leaks, numerical solution of approximate transport equations, numerical solution of transport equations for the simplest configurations making possible to decrease essentially a number of variables in the problem. The conclusion is drawn that the attained level of investigations on the problem of nuclear power plant shield optimization gives the possibility to pass on at present to the solution of problems with a more detailed account of the real shield operating conditions (shield temperature field account, its strength and other characteristics) [ru

    2006-01-01

    To determine the neutron shielding features of water-extended polyester a Monte Carlo study was carried out. Materials with low atomic number are predominantly used for neutron shielding because these materials effectively attenuate neutrons, mainly through inelastic collisions and absorption reactions. During the selection of materials to design a neutron shield, prompt gamma production as well as radionuclide production induced by neutron activation must be considered. In this investigation the Monte Carlo method was used to evaluate the performance of a water-extended polyester shield designed for the transportation, storage, and use of a 252 Cf isotopic neutron source. During calculations a detailed model for the 252 Cf and the shield was utilized. To compare the shielding features of water extended polyester, the calculations were also made for the bare 252 Cf in vacuum, air and the shield filled with water. For all cases the calculated neutron spectra was utilized to determine the ambient equivalent neutron dose at four sites around the shielding. In the case of water extended polyester and water shielding the calculations were extended to include the prompt gamma rays produced during neutron interactions, with this information the Kerma in air was calculated at the same locations where the ambient equivalent neutron dose was determined.

    Full Text Available The majority of respondents in fact doesn’t understand the concept of «economism», doesn’t consider the need for University to take part in the entrepreneurial activity and doesn’t recognize the need for the existence of the elements of the business structures in the higher education institutions. The University lost its primary purpose and becomes a huge supermarket, which offers various types of knowledge. Rational action is the desire to buy the most qualitative product – a diploma from a prestigious University, which can be successfully converted to the official and economic status. All this leads to the emergence of the Ukrainian form of commercialization, which differs from the Western one. Its significant difference lies in the bias, focus on profit, consumerism as a type of a consumer behavior. It has been mentioned in the article that in the educational system the principles of consumerism moved to the introduction of fees for various additional services (training, courses, testing classes, tests, etc.. The study of economism and the commercialization in the Ukrainian educational system is characterized by a peculiar relevance as it raises the issue of the dynamics and development of the modernization and transformation of the modern higher education. Commercialization is caused by a number of obstacles. The prioritative and harmonious development of the education system can be done only by the expense of state budget financing. In such circumstances, the University becomes a business entity for the provision of educational services. The attention in the article has been drawn to the nature and characteristics of the commercialization and economism. It has been noted that the state education policy as an integral part of social policy is one of the tools of state influence on the formation of social structures and is aimed at solving problems of societal level. This makes sociological examination of transformation processes in

    2017-01-01

    Nuclear medicine and radiotherapy centers equipped with high intensity X-ray or teletherapy sources use lead glasses as viewing windows to protect personal from radiation exposure. Lead is the main component of glass which is responsible for shielding against photons. It is therefore essential to check the shielding efficiency before they are put in use. This can be done by studying photon transmission through the lead glasses. The study of photon transmission in shielding materials has been an important subject in medical physics and is potential useful in the development of radiation shielding materials

    System requirements for cooling the shield within the vacuum vessel for the core test reactor are analyzed. The total heat to be removed by the coolant system is less than 22,700 Btu/hr, with an additional 4600 Btu/hr to be removed by the 2-inch thick steel plate below the shield. The maximum temperature of the concrete in the shield can be kept below 200 0 F if the shield plug walls are kept below 160 0 F. The walls of the two ''donut'' shaped shield segments, which are cooled by the water from the shield and vessel cooling system, should operate below 95 0 F. The walls of the center plug, which are cooled with nitrogen, should operate below 100 0 F. (U.S.)

    1990-01-01

    This paper reports on calculations which exist for estimating shielding required for radioactivity; however, they are often not applicable for the radionuclides and activities common in biomedical research. A variety of commercially available Lucite shields are being marketed to the biomedical community. Their advertisements may lead laboratory workers to expect better radiation protection than these shields can provide or to assume erroneously that very weak beta emitters require extensive shielding. The authors have conducted a series of shielding experiments designed to simulate exposures from the amounts of 32 P, 51 Cr and 125 I typically used in biomedical laboratories. For most routine work, ≥0.64 cm of Lucite covered with various thicknesses of lead will reduce whole-body occupational exposure rates of < 1mR/hr at the point of contact

    The purpose of our investigation was determination of allelic state of the H1 resistance gene against the pathotypes Ro1 and Ro4 of golden potato cyst nematode (Globodera rostochiensis) among Ukrainian and world potato (Solanum tuberosum ssp. tuberosum) cultivars. The allelic condition of the TG689 marker was determined by PCR with DNA samples isolated from tubers of potato and primers, one pair of which flanks the allele-specific region and the other one was used for the control of DNA quality. Among analyzed 77 potato cultivars the allele of marker associated with the H1-type resistance was found in 74% of Ukrainian and 90% foreign ones although some of those cultivars proved to be susceptible to the golden potato nematode in field. The obtained data confirm the presence of H1-resistance against golden nematode pathotypes Ro1 and Ro4 among the Ukrainian potato cultivars and efficiency of the used marker within the accuracy that has been declared by its authors.

    1994-01-01

    Openings of a plurality of shieldings for penetration members are aligned to each other, and penetration members are inserted from the openings. Then, the openings of the plurality of shielding members are slightly displaced with each other to make the penetration portions into a helical configuration, so that leakage of radiation is reduced. Upon removal of the members, reverse operation is conducted. When a flowable shielding material is used, the penetration portions are constituted with two plates having previously formed openings and pipes for connecting the openings with each other and a vessel covering the entire of them. After passing the penetration members such as a cable, the relative position of the two plates is changed by twisting, to form a helical configuration which reduces radiation leakage. Since they are bent into the helical configuration, shielding performance is extremely improved compared with a case that radiation leakage is caused from an opening of a straight pipe. In addition, since they can be returned to straight pipes, attachment, detachment and maintenance can be conducted easily. (N.H.)

    India's Liquid Metal Cooled Fast Breeder Reactor programme started with the construction of loop type 13MW(e) Fast Breeder Test Reactor (FBTR) which attained criticality in October 1985. With the experience of FBTR, the design work on pool type 500 MW(e) Prototype Fast Breeder Reactor (PFBR) which will be a forerunner for future commercial fast breeder reactors, has been started. The Top Shield forms the cover for the main vessel which contains the primary circuit. Argon cover gas separates the Top Shield from the free level of hot sodium pool (803K). The Top Shield which is of box type construction consists of control plug, two rotatable plugs and roof slab, assembled together, which provide biological shielding, thermal shielding and leak tight containment at the top of the main vessel. Heat is transferred from the sodium pool to the Top Shield through argon cover gas and through components supported by it and dipped in the sodium pool. The Top Shield should be maintained at the desired operating temperature by incorporating a cooling system inside it. Insulation may be provided below the bottom plate to reduce the heat load to the cooling system, if required. The thermal design of Top Shield consists of estimation of heat transfer to the Top Shield, selection of operating temperature, assessment of insulation requirement, design of cooling system and evaluation of transient temperature changes

    Full Text Available Similarly to other European countries, in Ukraine scholars can identify a developmental stage of emerging adulthood. Little work has been done to examine emerging adulthood in Eastern European countries, such as ex-Soviet Union republics like Ukraine, which are making the transition out of communism into the broader free-market economy of Western Europe. Conceptions of the transition to adulthood were examined using data from 117 persons (51 women, 66 men aged 16-34, including 43 adolescents (aged 16-19, 51 emerging adults (aged 20-29, and 23 young-to-midlife adults (aged 30-35. Participants indicated the characteristics necessary for a person to be considered an adult on a questionnaire containing 43 possible criteria. Results found that the majority of Ukrainian young people did not consider themselves to be adults. The top criteria endorsed emphasised aspects of chronological transitions as criteria for adulthood by a large majority in the study. Among the criteria indicated with least influence are family capacities.

  6. Radiation Attenuation and Stability of ClearView Radiation Shielding TM-A Transparent Liquid High Radiation Shield.

    Radiation exposure is a limiting factor to work in sensitive environments seen in nuclear power and test reactors, medical isotope production facilities, spent fuel handling, etc. The established choice for high radiation shielding is lead (Pb), which is toxic, heavy, and abidance by RoHS. Concrete, leaded (Pb) bricks are used as construction materials in nuclear facilities, vaults, and hot cells for radioisotope production. Existing transparent shielding such as leaded glass provides minimal shielding attenuation in radiotherapy procedures, which in some cases is not sufficient. To make working in radioactive environments more practicable while resolving the lead (Pb) issue, a transparent, lightweight, liquid, and lead-free high radiation shield-ClearView Radiation Shielding-(Radium Incorporated, 463 Dinwiddie Ave, Waynesboro, VA). was developed. This paper presents the motivation for developing ClearView, characterization of certain aspects of its use and performance, and its specific attenuation testing. Gamma attenuation testing was done using a 1.11 × 10 Bq Co source and ANSI/HPS-N 13.11 standard. Transparency with increasing thickness, time stability of liquid state, measurements of physical properties, and performance in freezing temperatures are reported. This paper also presents a comparison of ClearView with existing radiation shields. Excerpts from LaSalle nuclear power plant are included, giving additional validation. Results demonstrated and strengthened the expected performance of ClearView as a radiation shield. Due to the proprietary nature of the work, some information is withheld.

    Neutron shielding is achieved of interaction with material by moderation and absorption. Material that contains large amounts hydrogen atoms which are almost same neutron atomic weight is suited for fast neutron shielding material. Therefore, polymers containing high density hydrogen atom are being used for fast neutron shielding. On the other hand, composite materials containing high thermal neutron absorption cross section atom (Li, B, etc) are being used for thermal neutron shielding. However, these materials have low fast neutron absorption cross section. Therefore, these materials are not suited for fast neutron shielding. Hydrogen which has outstanding neutron energy reduction ability has very low thermal neutron absorption cross section, almost cannot be used for thermal neutron shielding. In this case, a large atomic number material (Pb, U, etc.) has been used. Thus, metal hydrides are considered as complement to concrete shielding material. Because metal hydrides contain high hydrogen density and elements with high atomic number. In this research neutron shielding performance and characteristic of nuclear about metal hydrides ((TiH{sub 2}, ZrH{sub 2}, HfH{sub 2}) is evaluated by experiment and MCNPX using {sup 252}Cf neutron source as purpose development shielding material to developed shielding material

    Ukraine is experiencing one of the most volatile HIV epidemics globally, fueled primarily by people who inject drugs (PWIDs), and a parallel incarceration epidemic. Opioid substitution therapy (OST) is internationally recognized as one of the most effective forms of treatment for opioid dependence and is among the most effective HIV prevention strategies available, yet efforts to adopt it in Ukraine's Criminal Justice System (CJS) have been thwarted. To understand the reluctance of the Ukrainian CJS to adopt OST despite the overwhelming evidence pointing to its health benefits and improved criminal justice outcomes, we conducted the first survey of Ukrainian prison administrative, medical and custodial staff (N=243) attitudes towards addiction in general, OST, and people living with HIV/AIDS (PLWHA) in representative regions of Ukraine. Results revealed that Ukrainian CJS workers' attitudes toward OST, PLWHA, and drug addiction were universally negative, but differed substantially along geographic and occupational lines. Whereas geographic and cultural proximity to the European Union drove positive attitudes in the west, in the southern region we observed an identifiability effect, as workers who worked directly with prisoners held the most positive attitudes. We also found that knowledge mediated the effect of drug intolerance on OST attitudes. In Ukraine, adoption of OST is more influenced by myths, biases and ideological prejudices than by existing scientific evidence. By elucidating existing attitudes among CJS personnel, this study will help to direct subsequent interventions to address the barriers to implementing evidence-based HIV prevention treatments.

    Full Text Available This study analyzes how migration transforms experiences of the self in Russian and Ukrainian women in Belgium, from a retrospective life course perspective. The author particularly focuses on gender identities in interaction with other aspects of the self such as educational and professional background, nationality and legal status. She aims both to highlight variation in gendered responses between Russian and Ukrainian women (inter-subjective variation, and within Russian and Ukrainian women (intra-subjective variation over time and in two life domains (family and the labour market. The present analysis draws on the transversal analysis of the FEMIGRIN-project, a Belgian science policy project on female migration that cross-compared 5 case studies of female migrants in Belgium. The results of this transversal analysis were grouped in the construction of several “characteristic” migration trajectories of female migrants in Belgium. The present article reconstructs these trajectories with the qualitative data of the Russian and Ukrainian case study, from a life course and intersectional theory perspective. The combined life course and intersectional research perspective enabled the author to study how personal goals, aspirations and experiences of the self are continuously interpreted and re-interpreted in the course of migration, in interaction with the surrounding environment. Since women’s migration life courses develop largely according to their legal status and migration type, the author can conclude that female migrants’ opportunities and constraints are highly determined by these social categories. The analysis reveals that women’s life courses seem to be less structured by the investment of individual level capacities than by policy determined categories.

    Radiation shielding analysis in nuclear engineering fields is an important technology which is needed for the calculation of reactor shielding as well as radiation related safety problems in nuclear facilities. Moreover, the design technology required in high level radioactive waste management and disposal facilities is faced on serious problems with rapidly glowing nuclear industry development, and more advanced technology has to be developed for tomorrow. The main purpose of this study is therefore to build up the self supporting ability of technology development for the radiation shielding analysis in order to achieve successive development of nuclear industry. It is concluded that basic shielding calculations are possible to handle and analyze by using our current technology, but more advanced technology is still needed and has to be learned for the degree of accuracy in two-dimensional shielding calculation.

    International Nuclear Information System (INIS)

    1970-07-01

    Based on the trades made within this study BATH (mixture of B 4 C, aluminum and TiH 1 . 8 ) was selected as the internal shield material. Borated titanium hydride can also meet the criteria with a competitive weight but was rejected because of schedular constraints. A baseline internal shield design was accomplished. This design resulted in a single internal shield weighing about 3300 lb for both manned and unmanned missions. WANL checks on ANSC calculations are generally in agreement, but with some difference in the prediction of the effectiveness of the Boral liner. All of the alternate NSS concepts in the system weight reduction program were rejected. While some did save shield weight, they complicated the NSS design to an unacceptable degree. Studies were made of the feasibility of manual maintenance of NSS components outside of the pressure vessel. The requirements of the NSS components located forward of the internal shield were considered from a thermal and radiation damage standpoint. (auth)

    Full text: Models of the neutron guide shielding for the out of bunker guides on the thermal and cold neutron beam lines of the OPAL Reactor (ANSTO) were constructed using the Monte Carlo code MCNP 4B. The neutrons that were not reflected inside the guides but were absorbed by the supermirror (SM) layers were noted to be a significant source of gammas. Gammas also arise from neutrons absorbed by the B, Si, Na and K contained in the glass. The proposed shielding design has produced compact shielding assemblies. These arrangements are consistent with safety requirements, floor load limits, and cost constraints. To verify the design a prototype was assembled consisting of 120mm thick Pb(96%)Sb(4%) walls resting on a concrete block. There was good agreement between experimental measurements and calculated dose rates for bulk shield regions. (authors)

    Many radiation shielding barriers in Cuba have been designed according to the criterion of Maxi-mum Projected Dose Rates. This fact has created the paradigm of low dose rates. Because of this, dose rate levels greater than units of Sv.h-1 would be considered unacceptable by many specialists, regardless of the real exposure times. Nowadays many shielding barriers are being designed using dose constraints in real exposure times. Behind the new barriers, dose rates could be notably greater than those behind the traditional ones, and it does not imply inadequate designs or constructive errors. In this work were obtained significant differences in dose rate levels and shield-ing thicknesses calculated by both methods for some typical installations. The work concludes that real exposure time approach is more adequate in order to optimise Radiation Protection, although this method should be carefully applied

    2001-01-01

    In any context in which color superconductivity arises in nature, it is likely to involve pairing between species of quarks with differing chemical potentials. For suitable values of the differences between chemical potentials, Cooper pairs with nonzero total momentum are favored, as was first realized by Larkin, Ovchinnikov, Fulde, and Ferrell (LOFF). Condensates of this sort spontaneously break translational and rotational invariance, leading to gaps which vary periodically in a crystalline pattern. Unlike the original LOFF state, these crystalline quark matter condensates include both spin-zero and spin-one Cooper pairs. We explore the range of parameters for which crystalline color superconductivity arises in the QCD phase diagram. If in some shell within the quark matter core of a neutron star (or within a strange quark star) the quark number densities are such that crystalline color superconductivity arises, rotational vortices may be pinned in this shell, making it a locus for glitch phenomena

    A radiation shielding brick for use in building dry walls to form radiation proof enclosures and other structures is described. It is square in shape and comprises a sandwich of an inner layer of lead or similar shielding material between outer layers of plastics material, for structural stability. The ability to mechanically interlock adjacent bricks is provided by shaping the edges as cooperating external and internal V-sections. Relatively leak-free joints are ensured by enlarging the width of the inner layer in the edge region. (author)

    Full Text Available By drawing on Ukrainian experience, this paper analyzes the anatomy of bank efficiency in a transitional economy. Acknowledging the vast disparities in the business technology of different size banks, in this comprehensive study, we innovatively estimate group-specific (distinct frontiers for small, medium, and large size banks. The results from separate frontiers reveal that Ukrainian banks record 38% technical inefficiency, 26% pure technical inefficiency, and 17% scale inefficiency on average. Apparently, banks in transition waste about the two fifths of their factor inputs during the production of financial services. The cardinal source of sub-performance in transitional banks seems to be managerial inefficiencies. We also found that banks operating in areas with more political influence and more developed infrastructure outperform the banks operating in politically and economically weaker regions. The results also indicate that larger banks, enjoying public trust in a risky business climate, dominate smaller banks in all forms of efficiency. However, such bias for size causes large banks to suffer from decreasing returns to scale and small banks from idle capacity. Consequently, the policies promoting consolidation between small and large banks may alleviate the excess (idle capacity for large (small banks in a transitional economy.

    Full Text Available A nipple shield is a breastfeeding aid with a nipple-shaped shield that is positioned over the nipple and areola prior to nursing. Nipple shields are usually recommended to mothers with flat nipples or in cases in which there is a failure of the baby to effectively latch onto the breast within the first two days postpartum. The use of nipple shields is a controversial topic in the field of lactation. Its use has been an issue in the clinical literature since some older studies discovered reduced breast milk transfer when using nipple shields, while more recent studies reported successful breastfeeding outcomes. The purpose of this review was to examine the evidence and outcomes with nipple shield use. Methods: A literature search was conducted in Ovid MEDLINE, OLDMEDLINE, EMBASE Classic, EMBASE, Cochrane Central Register of Controlled Trials and CINAHL. The primary endpoint was any breastfeeding outcome following nipple shield use. Secondary endpoints included the reasons for nipple shield use and the average/median length of use. For the analysis, we examined the effect of nipple shield use on physiological responses, premature infants, mothers’ experiences, and health professionals’ experiences. Results: The literature search yielded 261 articles, 14 of which were included in this review. Of these 14 articles, three reported on physiological responses, two reported on premature infants, eight reported on mothers’ experiences, and one reported on health professionals’ experiences. Conclusion: Through examining the use of nipple shields, further insight is provided on the advantages and disadvantages of this practice, thus allowing clinicians and researchers to address improvements on areas that will benefit mothers and infants the most.

  4. Hot Cell Window Shielding Analysis Using MCNP

    The Idaho National Laboratory Materials and Fuels Complex nuclear facilities are undergoing a documented safety analysis upgrade. In conjunction with the upgrade effort, shielding analysis of the Fuel Conditioning Facility (FCF) hot cell windows has been conducted. This paper describes the shielding analysis methodology. Each 4-ft thick window uses nine glass slabs, an oil film between the slabs, numerous steel plates, and packed lead wool. Operations in the hot cell center on used nuclear fuel (UNF) processing. Prior to the shielding analysis, shield testing with a gamma ray source was conducted, and the windows were found to be very effective gamma shields. Despite these results, because the glass contained significant amounts of lead and little neutron absorbing material, some doubt lingered regarding the effectiveness of the windows in neutron shielding situations, such as during an accidental criticality. MCNP was selected as an analysis tool because it could model complicated geometry, and it could track gamma and neutron radiation. A bounding criticality source was developed based on the composition of the UNF. Additionally, a bounding gamma source was developed based on the fission product content of the UNF. Modeling the windows required field inspections and detailed examination of drawings and material specifications. Consistent with the shield testing results, MCNP results demonstrated that the shielding was very effective with respect to gamma radiation, and in addition, the analysis demonstrated that the shielding was also very effective during an accidental criticality.

    Gamma rays have high penetration power and its attenuation depends upon the thickness and the attenuation coefficient of the shield, so it is necessary to use the high density shield to attenuate the gamma rays. Heavy concrete is considered to be used for high radiation laboratory and the testing of the shielding ability and compressibility of various types of heavy concrete composed of baryte, hematite, ilmenite and galena is carried out. The results of this study show that baryte-ilmenite concrete is the most suitable for high radiation laboratory in Thailand

    A Monte Carlo study to determine the shielding features to neutrons of water-extended polyester (WEP) was carried out. Materials with low atomic number are predominantly used for neutron shielding because these materials effectively attenuate neutrons, mainly through elastic and inelastic collisions. In addition to neutron attenuation properties, other desirable properties for neutron shielding materials include mechanical strength, stability, low cost, and ease of handling. During the selection of materials to design a neutron shield, prompt gamma production as well as radionuclide induced by neutron activation must be considered. In this investigation the Monte Carlo method (MCNP code) was used to evaluate the performance of a water-extended polyester shield designed for the transportation, storage, and use of a 252 Cf isotopic neutron source, for comparison the calculations were extended to water shielding, the bare source in vacuum and in air.

    2015-09-01

    Full Text Available Thick and homogeneous hybrid film systems based on poly(methyl methacrylate (PMMA and CeO2 nanoparticles were synthesized using the melt compounding method to improve thermal stability, mechanical and UV-shielding properties, as well as to propose them for use in the multifunctional materials industry. The effect of the inorganic phase on these properties was assessed by using two different weight percentages of synthesized CeO2 nanoparticles (0.5 and 1.0 wt % with the sol–gel method and thermal treatment at different temperatures (120, 235, 400, 600 and 800 °C. Thereafter, the nanoceria powders were added to the polymer matrix by single screw extrusion. The absorption in the UV region was increased with the crystallite size of the CeO2 nanoparticles and the PMMA/CeO2 weight ratio. Due to the crystallinity of CeO2 nanoparticles, the thermal, mechanical and UV-shielding properties of the PMMA matrix were improved. The presence of CeO2 nanostructures exerts an influence on the mobility of PMMA chain segments, leading to a different glass transition temperature.

  13. Space Shielding Materials for Prometheus Application

    2006-01-20

    At the time of Prometheus program restructuring, shield material and design screening efforts had progressed to the point where a down-selection from approximately eighty-eight materials to a set of five ''primary'' materials was in process. The primary materials were beryllium (Be), boron carbide (B{sub 4}C), tungsten (W), lithium hydride (LiH), and water (H{sub 2}O). The primary materials were judged to be sufficient to design a Prometheus shield--excluding structural and insulating materials, that had not been studied in detail. The foremost preconceptual shield concepts included: (1) a Be/B{sub 4}C/W/LiH shield; (2) a Be/B{sub 4}C/W shield; (3) and a Be/B{sub 4}C/H{sub 2}O shield. Since the shield design and materials studies were still preliminary, alternative materials (e.g., {sup nal}B or {sup 10}B metal) were still being screened, but at a low level of effort. Two competing low mass neutron shielding materials are included in the primary materials due to significant materials uncertainties in both. For LiH, irradiation-induced swelling was the key issue, whereas for H{sub 2}O, containment corrosion without active chemistry control was key, Although detailed design studies are required to accurately estimate the mass of shields based on either hydrogenous material, both are expected to be similar in mass, and lower mass than virtually any alternative. Unlike Be, W, and B{sub 4}C, which are not expected to have restrictive temperature limits, shield temperature limits and design accommodations are likely to be needed for either LiH or H{sub 2}O. The NRPCT focused efforts on understanding swelting of LiH, and observed, from approximately fifty prior irradiation tests, that either casting ar thorough out-gassing should reduce swelling. A potential contributor to LiH swelling appears to be LiOH contamination due to exposure to humid air, that can be eliminated by careful processing. To better understand LiH irradiation performance and

    In the compact accelerator based DD neutron generator, the deuterium ions generated by the ion source are accelerated after the extraction and bombarded to a deuterated titanium target. The emitted neutrons have typical energy of ∼2.45MeV. Utilization of these compact accelerator based neutron generators of yield up to 10 9 neutron/second (DD) is under active consideration in many research laboratories for conducting active neutron interrogation experiments. Requirement of an adequately shielded laboratory is mandatory for the effective and safe utilization of these generators for intended applications. In this reference, we report the comprehensive analysis of shielding effectiveness for High Density Polyethylene (HDPE), Borated Polyethylene (BPE) and Concrete as candidate materials for neutron shielding. In shielding calculations, neutron induced scattering and absorption gamma dose has also been considered along with neutron dose. Contemporarily any material with higher hydrogenous concentration is best suited for neutron shielding. Choice of shielding material is also dominated by practical issues like economic viability and availability of space. Our computational analysis results reveal that utilization of BPE sheets results in minimum wall thickness requirement for attaining similar range of attenuation in neutron and gamma dose. The added advantage of using borated polyethylene is that it reduces the effect of both neutron and gamma dose by absorbing neutron and producing lithium and alpha particle. It has also been realized that for deciding upon optimum thickness determination of any shielding material, three important factors to be necessarily considered are: use factor, occupancy factor and work load factor.

    Full Text Available Shielding neutrons involve three steps that are slowing neutrons, absorption of neutrons, and impregnation of gamma rays. Neutrons slow down with thermal energy by hydrogen, water, paraffin, plastic. Hydrogenated materials are also very effective for the absorption of neutrons. Gamma rays are produced by neutron (radiation retention on the neutron shield, inelastic scattering, and degradation of activation products. If a source emits gamma rays at various energies, high-energy gamma rays sometimes specify shielding requirements. Multipurpose Materials for Neutron Shields; Concrete, especially with barium mixed in, can slow and absorb the neutrons, and shield the gamma rays. Plastic with boron is also a good multipurpose shielding material. In this study; new applications and developments in the area of neutron shielding will be discussed in terms of different materials.

    The molecular chaperones, α-crystallins, belong to the small heat shock protein (sHSP) family and prevent the aggregation and insolubilization of client proteins. Studies in vivo have shown that the chaperone activity of the α-crystallins is raised or lowered in various disease states. Therefore, the development of tools to control chaperone activity may provide avenues for therapeutic intervention, as well as enable a molecular understanding of chaperone function. The major human lens α-crystallins, αA- (HAA) and αB- (HAB), share 57% sequence identity and show similar activity towards some clients, but differing activities towards others. Notably, both crystallins contain the "α-crystallin domain" (ACD, the primary client binding site), like all other members of the sHSP family. Here we show that RNA aptamers selected for HAA, in vitro, exhibit specific affinity to HAA but do not bind HAB. Significantly, these aptamers also exclude the ACD. This study thus demonstrates that RNA aptamers against sHSPs can be designed that show high affinity and specificity - yet exclude the primary client binding region - thereby facilitating the development of RNA aptamer-based therapeutic intervention strategies.

    Shielding research as an independent subject in France dates from 1956. The importance of these studies has been reflected in the contribution which they have made to power reactor design and in the resultant savings in expenditure for civil engineering and machinery for the removal of mobile shields. The Reactor Shielding Research Division numbers approximately 60 persons and uses several experimental facilities. These include: NAIADE I, installed near the ZOE reactor and operating with a natural uranium slab 2 cm thick (an effective diameter of 60 cm is the one most commonly used); the TRITON pool-type reactor, mainly used in shielding studies, includes an active-water loop, by means of which the secondary shields required for light-water reactors can be studied; core, NEREIDE, which is situated near a 2 m x 2 m aluminium window enables a large neutron source to be placed in a compartment without water in which large-scale mock-ups can be mounted for the study, in particular, of neutron diffusion in large cavities, and of reactor shielding of greater thickness than that in NAIADE I; SAMES 600 keV accelerator is used for monoenergetic neutron studies. Instrumentation studies are an important part of the work, mainly in the measurement of fast neutrons and their spectra by activation detectors. Of late, attention has been directed towards the use of (n, n') (rhodium) reactions and of heavy detectors for low-flux measurements. The simultaneous use of a large number of detectors poses automation problems. With our installation we can count 16 detectors simultaneously. Neutron spectrum studies are conducted with nuclear emulsions and a lithium-6 semiconductor spectrometer. As to the materials used, the research carried out in France involves chiefly graphite, iron and concrete at various temperatures up to 800 deg C. Different compounds, borated and non-borated and of densities up to between 1 and 9 are under consideration. Problems connected with applications are

    Reactors of the water-cooled type and a means for shielding such a rcactor to protect operating personnel from harmful radiation are discussed. In this reactor coolant tubes which contain the fissionable material extend vertically through a mass of moderator. Liquid coolant enters through the bottom of the coolant tubes and passes upwardly over the fissionable material. A shield tank is disposed over the top of the reactor and communicates through its bottom with the upper end of the coolant tubes. A hydrocarbon shielding fluid floats on the coolant within the shield tank. With this arrangements the upper face of the reactor can be opened to the atmosphere through the two superimposed liquid layers. A principal feature of the invention is that in the event radioactive fission products enter thc coolant stream. imposed layer of hydrocarbon reduces the intense radioactivity introduced into the layer over the reactors and permits removal of the offending fuel material by personnel shielded by the uncontaminated hydrocarbon layer.

    This report contains the design, fabrication and accurate installation of ST3 shield, which would be installed at ST3 beam port of HANARO. At first, we designed and fabricated ST3 shield casemate composed of 14 blocks. We filled it with heavy concrete, lead ingot and polyethylene that mixed B 4 C powder and epoxy. The average filling density of total shield casemate was 4.7g/cm 3 . The developed ST3 shield was installed at the ST3 beam port and the accuracy of installation for each beam path and channel was evaluated. We found that the extraction of neutron beam to meet the requirement of neutron spectrometer is possible. Also, we developed ancillary equipment such as BGU, quick shutter and exterior shield door for the effective opening and closing of neutron beam. As a result of this study, it was found that neutron spectrometer such as neutron reflectometer and high intensity powder diffractomater can be installed at the ST3 beam port

    The ablation and penetration of pellets in early ORMAK and ISX-A experiments were reliably predicted by the neutral gas shielding model of Milora and Foster. These experiments demonstrated that the principle components of the model - a self-generated shield which reduces the heat flux at the plasma surface - were correct. In more recent experiments with higher temperature plasmas, this model consistently predicts greater penetration than observed in the experiments. Upgarding known limitations of the original model brings the predicted and observed penetration values into agreement. These improvements include: (1) treating the incident electrons as having distribution in energy rather than being monoenergetic; (2) including the shielding effects of cold, dense plasma extending along the magnetic field outside the neutral shield; and (3) modifying the finite plasma, self-limiting incident heat flux so that it represents a collisionless plasma limit rather than a collisional limit. Comparisons are made between the models for a selection of ISX-B Alcator-C, and TFTR shots. The net effect of the changes in the model is an increase in pellet ablation rates and decrease in penetration for current and future experiments

    Poor definition of the heating profiles that occur during normal operation of Faraday shields for ion cyclotron resonant frequency (ICRF) antennas has complicated the mechanical design of ICRF system components. This paper reports that at Oak Ridge National Laboratory (ORNL), Faraday shield analysis is being used in defining rf heating profiles. In recent numerical analyses of proposed hardware for the Burning Plasma Experiment (BPX) and DIII-D, rf magnetic fields at Faraday shield surfaces were calculated, providing realistic predictions of the induced skin currents flowing on the shield elements and the resulting dissipated power profile. Detailed measurements on mock-ups of the Faraday shields for DIII-D and the Tokamak Fusion Test Reactor (TFTR) confirmed the predicted magnetic field distributions. A conceptual design for an uncooled Faraday shield for the BPX ion cyclotron resonance heating (ICRH) antenna, which should withstand the proposed long-pulse operation, has been completed. The analytical effort is described in detail, with emphasis on the design work for the BPX ICRH antenna conceptual design and for the replacement Faraday shield for the DIII-D FWCD antenna. Results of analyses are shown, and configuration issues involved in component modeling are discussed

  11. Shielding calculation for bremsstrahlung from β-emitters

    Accompanying the revision of radiation injury prevention law, the shielding calculation method for photon corresponding to the dose equivalent was shown. However, regarding the electron from β decay nuclide and bremsstrahlung caused by shielding material, the shielding calculation method corresponding to the 1 cm dose equivalent has not been reported, hence, in this report, the spectrum of β-ray is calculated and the 1 cm dose equivalent transmission rate of the bremsstrahlung was calculated for three kinds of shielding materials (iron, lead, concrete). As the result of consideration, it is sufficient to think about the bremsstrahlung due to negative electron emission accompanying β-decay. In β-decay, electrons which constitute the continuous spectrum with maximum energy are emitted. The shape of the spectrum differs with nuclides. The maximum energy of β-ray of generally used nuclides is mostly below 3MeV and, besides, the electron ray itself is easily shielded, while the strength of bremsstrahlung depends on the atomic number of shielding materials and its generating mechanism is complicated. In this report, the actual shielding calculation method for bremsstrahlung is shown with regard to the most frequently used β-decay nuclides. (M.T.)

    This report describes a preliminary evaluation of the shielding design of FY98 KALIMER. The KALIMER shielding design includes the Inner Fixed Shield of a stainless cylinder located inside the support barrel; the Radial PSDRS Shields which are three B{sub 4}C cylinders located outside the support barrel at core level; the Lower IHX shield of a cylindrical B{sub 4}C plate located above the flow guide; and Inner and Outer IHX shields of B{sub 4}C cylinders located inside and outside of the support barrel, respectively. The DORT3.1 two-dimensional transport code was used to evaluate the KALIMER shielding design. The reactor system was represented by four axial zones, each of which was modeled in the R-Z geometry. The KAFAX-F22 library was used in the analyses, which was generated from the JEF-2.2 of OECD/NEA files for LMR applications by KAERI. The performance of the KALIMER shielding design is compared against the shielding design criteria. The results indicate that the support barrel, upper grid plate, and other reactor structures meet the maximum neutron fluence and DPA limits established in the shielding design criteria. Activities of the air effluent in the PSDRS were also evaluated and are shown to satisfy the maximum permissible concentration (MPC) limits in 10 CFR Part 20. In the future, the validation of the DORT model by a detailed three dimensional calculation such as MCNP and the justification of the current shielding design limits are needed.

    A small commercial SEM had been successfully shielded for examining radioactive materials transferred directly from a remote handling facility. Relatively minor mechanical modifications were required to achieve excellent operation. Two inches of steel provide adequate shielding for most samples encountered. However, samples reading 75 rad/hr γ have been examined by adding extra shielding in the form of tungsten sample holders and external lead shadow shields. Some degradation of secondary electron imaging was seen but was adequately compensated for by changing operating conditions

    Full Text Available The modern practice of forestry production in Ukraine, which is in the process of implementing the conceptual changes in forest management and harmonization of its basic approaches to the basics of sustainable development, requires a significant expansion of the current regulatory and informational tools used to assess the ecological functions of forests. For this purpose, during the 2012–2014, as part of an international project GESAPU, models and tables of bioproductivity for forest tree species in Ukraine were completed. The article presents the results of modeling the dynamics of the conversion coefficients for the main components of phytomass of modal natural spruce forests of the Carpathian region of Ukraine based on information from 32 plots in the database of «Forest Phytomass of Ukraine». According to the state forest accounting of Ukraine as of January 1, 2011, the spruce forests in the Ukrainian Carpathians cover an area of 426.2 thousand ha, 45 % of which are spruce of natural origin. To evaluate the productivity of modal dynamics of pure and mixed spruce stands, the study developed models of the stock and overall productivity, derived by Bertalanffy growth function. On the basis of these models, normative reference tables of biological productivity of natural modal spruce forests of the Ukrainian Carpathians were developed. To successfully meet the challenges of evaluating the energy possibilities of forestry of Ukraine, the study used tables of energetic productivity of investigated stands. Built on the basis of the tables of bioproductivity, they reflect the dynamic processes of energy storage in the phytomass components and can be used in forest management to predict volumes of energetic woods.

    Full Text Available The paper seeks to develop an analysis of the South Stream project in view of the Ukrainian crisis. We cannot put aside the internal factor as Ukraine is facing serious internal issues such as corruption and instability, therefore Russia’s invasion of Ukraine can not be simply ignored in this pipeline project. The article uses mostly facts that happened throughout last years, as well as for and against declarations in the case of the South Stream project and its mother Russia. When we hear about South Stream, we think of Russia and since 2007, this pipeline has encouraged Putin’s faith in energy superpower. A good point to start with was to gather all declarations since then and cover all actions that regard the South Stream game. In Russian foreign policy for the South Stream race, Soft Power was used more than enough and it has recently made room for Hard Power, which is the Ukraine never ending episode. Insights of the South Stream story have been lately related both softly and hardly, this is the reason why I have chosen to analyse both sides in order to complete the energy landscape.

    Full Text Available Ukraine takes a fourth place in the world in the technical hemp production and can use waste of hemp for biofuel (including biodiesel production. This paper presents an analysis of cetane numbers and low-temperature properties of hemp biodiesels as well as spray and evaporation of these fuels. Two types of hemp biodiesel fuels are analyzed: Hemp Methyl esters, produced from hemp oil in Ukraine (HM1 and European Union (HM2. It was found that hemp biodiesel has smaller cetane number than traditional rapeseed or soy biodiesel. At the same time hemp biodiesel shows better low-temperature properties compared with traditional biodiesels. So, it was recommended to use the mixture of rapeseed or soy biodiesel with hemp biodiesel to optimise both the low-temperature properties and cetane number of fuel. According to modelling the spray parameters of hemp biodiesel are very close to those of soy biodiesel. Evaporation of hemp biodiesel is very close to soy biodiesel according to previous research. Therefore, mixture of soy/rapeseed and hemp biodiesels can be recommended for experimental investigation as a future fuel for Ukrainian market.

    Purpose: Lead aprons are routinely used to shield the fetus from radiation during fluoroscopically guided interventions (FGI) involving pregnant patients. When placed in the primary beam, lead aprons often reduce image quality and increase fluoroscopic radiation output, which can adversely affect fetal dose. The purpose of this work is to identify an effective and practical method to reduce fetal dose without affecting image quality. Methods: A pregnant patient equivalent abdominal phantom is set on the table along with an image quality test object (CIRS model 903) representing patient anatomy of interest. An ion chamber is positioned at the x-ray beam entrance to the phantom, which is used to estimate the relative fetal dose. For three protective methods, image quality and fetal dose measurements are compared to baseline (no protection):1. Lead apron shielding the entire abdomen; 2. Lead apron shielding part of the abdomen, including the fetus; 3. Narrow collimation such that fetus is excluded from the primary beam. Results: With lead shielding the entire abdomen, the dose is reduced by 80% relative to baseline along with a drastic deterioration of image quality. With lead shielding only the fetus, the dose is reduced by 65% along with complete preservation of image quality, since the image quality test object is not shielded. However, narrow collimation results in 90% dose reduction and a slight improvement of image quality relative to baseline. Conclusion: The use of narrow collimation to protect the fetus during FGI is a simple and highly effective method that simultaneously reduces fetal dose and maintains sufficient image quality. Lead aprons are not as effective at fetal dose reduction, and if placed improperly, they can severely degrade image quality. Future work aims to investigate a wider variety of fluoroscopy systems to confirm these results across many different system geometries.

    The Waste Management and Remedial Action Division has planned a modification sequence for storage facility 7827 in the Solid Waste Storage Area (SWSA). The modification cycle is: (1) modify an empty caisson, (2) transfer the spent nuclear fuel (SNF) of an occupied caisson to a hot cell in building 3525 for inspection and possible repackaging, and (3) return the package to the modified caisson in the SWSA. Although the SNF to be moved is in the solid form, it has different levels of activity. Thus, the following 5 shipping casks will be available for the task: the Loop Transport Carrier, the In- Pile Loop LITR HB-2 Carrier, the 6.5-inch HRLEL Carrier, the HFIR Hot Scrap Carrier, and the 10-inch ORR Experiment Removal Shield Cask. This report describes the shielding tasks for the 5 casks: determination of shielding characteristics, any streaming avenues, estimation of thermal limits, and shielding calculational uncertainty for use in the transportation plan

    To determine the neutron shielding features of water-extended polyester a Monte Carlo study was carried out. Materials with low atomic number are predominantly used for neutron shielding because these materials effectively attenuate neutrons, mainly through inelastic collisions and absorption reactions. During the selection of materials to design a neutron shield, prompt gamma production as well as radionuclide production induced by neutron activation must be considered. In this investigation the Monte Carlo method was used to evaluate the performance of a water-extended polyester shield designed for the transportation, storage, and use of a {sup 252}Cf isotopic neutron source. During calculations a detailed model for the {sup 252}Cf and the shield was utilized. To compare the shielding features of water extended polyester, the calculations were also made for the bare {sup 252}Cf in vacuum, air and the shield filled with water. For all cases the calculated neutron spectra was utilized to determine the ambient equivalent neutron dose at four sites around the shielding. In the case of water extended polyester and water shielding the calculations were extended to include the prompt gamma rays produced during neutron interactions, with this information the Kerma in air was calculated at the same locations where the ambient equivalent neutron dose was determined.

    1993-01-01

    The radiation shield optimization code SWAN (Ref. 1) was originally developed for minimizing the thickness of a shield that will meet a given dose (or another) constraint or for extremizing a performance parameter of interest (e.g., maximizing energy multiplication or minimizing dose) while maintaining the shield volume constraint. The SWAN optimization process proved to be highly effective (e.g., see Refs. 2, 3, and 4). The purpose of this work is to investigate the applicability of the SWAN methodology to problems in which the weight rather than the volume is the relevant shield characteristic. Such problems are encountered in shield design for space nuclear power systems. The investigation is carried out using SWAN with the coupled neutron-photon cross-section library FLUNG (Ref. 5)

    In deep penetration transport calculations, the integral design parameters is determined mainly by secondary particles which are produced by interactions of the primary radiation with materials. The shield thickness and the biological dose rate at a given point of a bulk shield are determined from the contribution from secondary gamma rays. The heat generation and the radiation damage in the structural and shield materials depend strongly on the secondary gamma rays. In this paper, the status of the secondary gamma ray data and its further problems are described from the viewpoint of shield design. The secondary gamma-ray data in ENDF/B-IV and POPOP4 are also discussed based on the test calculations made for several shield assemblies. (author)

    TIBER features a segmented shield assembly that provides the nuclear shielding for the superconducting toroidal field coils. In addition to its primary function, the shield also provides tritium breeding through the use of water coolant that contains 16 wt% dissolved lithium nitrate. Because the TIBER reactor need not provide electrical power, the coolant is maintained at low pressure (0.2 MPa) and low temperature (75/sup 0/C). The shield is made in several segments to facilitate assembly and allow for replacement of high heat flux components (divertor blades). The segments are designated as inboard, outboard, upper, lower, and divertor modules. In total, there are 96 separate modules in the machine, consisting of six different types. The design features of the different modules vary primarily depending on the thickness of the shield in a given location. The very thick outboard shield has a breeding zone in the inboard portion of the module, with a shielding zone behind it. The breeding zone consists of a stainless steel casing filled with beryllium spheres. The shielding zone consists of the same casing filled with steel spheres. Both of these zones have lithiated water circulated throughout to provide cooling and breeding. In zones with minimal thickness, tungsten alloys are used to achieve the required shielding. These alloys are incoprorated in subassemblies utilizing stainless steel casings surrounding blocks of tungsten heavy metal alloy. These are infiltrated with lead on final assembly to form a thermally continuous panel. Several of these panels are then assembled into an outer stainless steel case to form an inboard module. These modules also use the lithiated coolant. The details of the design are presented and discussed. (orig.).

    Concrete is one of the most important construction materials which widely used as a neutron shielding. Neutron shield is obtained of interaction with matter depends on neutron energy and the density of the shielding material. Shielding properties of concrete could be improved by changing its composition and density. High density materials such as iron or high atomic number elements are added to concrete to increase the radiation resistance property. In this study, shielding properties of concrete were investigated by adding iron, FeB, Fe2B, stainless - steel at different ratios into concrete. Neutron dose distributions and shield design was obtained by using FLUKA Monte Carlo code. The determined shield thicknesses vary depending on the densities of the mixture formed by the additional material and ratio. It is seen that a combination of iron rich materials is enhanced the neutron shielding of capabilities of concrete. Also, the thicknesses of shield are reduced.

    A computer code written in pascal language for IBM/Pc is described. The program calculates the optimum thickness of slab shield for different geometries sources. The Point Kernel Method is employed, which enables the obtention of the ionizing radiation flux density. The calculation takes into account the possibility of self-absorption in the source. The air kerma rate for gamma radiation is determined, and with the concept of attenuation length through the equivalent attenuation length the shield is obtained. The scattering and the exponential attenuation inside the shield material is considered in the program. The shield materials can be: concrete, water, iron or lead. It also calculates the shield for point isotropic neutron source, using as shield materials paraffin, concrete or water. (authors). 13 refs

    A combined measurement and Monte-Carlo simulation study was carried out in order to characterize the particle self-shielding effect of B4C grains in neutron shielding concrete. Several batches of a specialized neutron shielding concrete, with varying B4C grain sizes, were exposed to a 2 Å neutron beam at the R2D2 test beamline at the Institute for Energy Technology located in Kjeller, Norway. The direct and scattered neutrons were detected with a neutron detector placed behind the concrete blocks and the results were compared to Geant4 simulations. The particle self-shielding effect was included in the Geant4 simulations by calculating effective neutron cross-sections during the Monte-Carlo simulation process. It is shown that this method well reproduces the measured results. Our results show that shielding calculations for low-energy neutrons using such materials would lead to an underestimate of the shielding required for a certain design scenario if the particle self-shielding effect is not included in the calculations.

    For the examination of spent fuels and high radioactive specimens using a specially equipped scanning electron microscope, a shielded glove box was designed and constructed at PIE facility of KAERI. This glove box consisted of shielding walls, containment box, lead glasses, manipulators, gloves, ventilation systems, doors, hot-cell specimen cask adapter, etc. It was emphasized that both the easy operation and radiation safety are important factors in the shielded glove box were installed also considered as a important factor to build the basic concept of the assembling. Two sliding doors and one hinge-type door were installed for the easy installation, operation and maintenance of scanning electron microscope. Containment box which confines the radioactive material into the box consisted of reinforced transparent glasses, aluminum frames and stainless steel plate liner. Therefore everything beyond the containment box can be seen through the lead glass which installed at the front shielding wall. All shielding walls and doors were introduced separately into the room and assembled by bolting. (author). 3 refs., 5 tabs., 18 figs

    1987-10-01

    The neutral gas shielding model for ablation of frozen hydrogenic pellets is extended to include the effects of an initial Maxwelliam distribution of incident electron energies; a cold plasma shield outside the neutral shield and extended along the magnetic field; energetic neutral beam ions and alpha particles; and self-limiting electron ablation in the collisionless plasma limit. Including the full electron distribution increases ablation, but adding the cold ionized shield reduces ablation; the net effect is a modest reduction in pellet penetration compared with the monoenergetic electron neutral shielding model with no plasma shield. Unlike electrons, fast ions can enter the neutral shield directly without passing through the cold ionized shield because their gyro-orbits are typically larger than the diameter of the cold plasma tube. Fast alpha particles should not enhance the ablation rate unless their population exceeds that expected from local classical thermalization. Fast beam ions, however, may enhance ablation in the plasma periphery if their population is high enough. Self-limiting ablation in the collisionless limit leads to a temporary distortion of the original plasma electron Maxwellian distribution function through preferential depopulation of the higher-energy electrons. 23 refs., 9 figs

    Simulations were performed describing the motion and breakup of energetic C 60 ions interacting with crystalline targets. A hybrid algorithm was used that employs a binary collision model for the scattering of the carbon ions by the atoms of the solid, and molecular dynamics for the Coulomb interactions of the 60 carbon ions with one another. For the case of yttrium iron garnet (YIG), directions such as [1 1 0], [1 0 0], [0 1 0] and [0 0 1] demonstrate channelling for a large fraction of the C ions. For directions such as [1 1 1], [2 1 1] and [7 5 3] the trajectories show no more channelling than for random directions. The effects of tilt, shielding and wake-field interactions were investigated for YIG and α-quartz

    "COR-RA" (colorless atomic oxygen resistant -- radiation shield) is the name of a transparent polymeric material filled with x-ray-absorbing salts of lead, bismuth, cesium, and thorium. COR-RA is suitable for use in shielding personnel against bremsstrahlung radiation from electron-beam welding and industrial and medical x-ray equipment. In comparison with lead-foil and leaded-glass shields that give equivalent protection against x-rays (see table), COR-RA shields are mechanically more durable. COR-RA absorbs not only x-rays but also neutrons and rays without adverse effects on optical or mechanical performance. The formulation of COR-RA with the most favorable mechanical-durability and optical properties contains 22 weight percent of bismuth to absorb x-rays, plus 45 atomic percent hydrogen for shielding against neutrons.

    2016-10-01

    In this work, radio frequency shielding behaviour of polymer (epoxy) matrixes composed of E-glass fibres and Fe2O3 fillers have been studied. The principal aim of this project is to prepare suitable shielding material for RFID application. When RFID unit is pasted on a metal plate without shielding material, the sensing distance is reduced, resulting in a less than useful RFID system. To improve RF shielding of epoxy, fibres and fillers were utilized. Magnetic behaviour of epoxy polymer composites was measured by hysteresis graphs (B-H) followed by radio frequency identifier setup. Fe2O3 particles of sizes 800, 200 and 100 nm and E-glass fibre woven mat of 600 g/m2 were used to make composites. Particle sizes of 800 nm and 200 nm were prepared by high-energy ball milling, whereas particles of 100 nm were prepared by sol-gel method. To enhance better dispersion of particles within the epoxy matrix, a surface modification process was carried out on fillers by an amino functional coupling agent called 3-Aminopropyltrimethoxysilane (APTMS). Crystalline and functional groups of siliconized Fe2O3 particles were characterized by XRD and FTIR spectroscopy analysis. Variable quantity of E-glass fibre (25, 35, and 45 vol%) was laid down along with 0.5 and 1.0 vol% of 800, 200, and 100 nm size Fe2O3 particles into the matrix, to fabricate the hybrid composites. Scanning electron microscopy and transmission electron microscopy images reveal the shape and size of Fe2O3 particles for different milling times and particle dispersion in the epoxy matrix. The maximum improved sensing distance of 45.2, 39.4 and 43.5 % was observed for low-, high-, and ultra-high radio frequency identifier setup along with shielding composite consist of epoxy, 1 vol% 200 nm Fe2O3 particles and 45 vol% of E-glass fibre.

    Alternative advanced technologies are being evaluated for use in cooling the Faraday shields used for protection of ion cyclotron range of frequencies (ICR) antennae in Tokamaks. Two approaches currently under evaluation include heat pipe cooling and gas cooling. A Monel/water heat pipe cooled Faraday shield has been successfully demonstrated. Heat pipe cooling offers the advantage of reducing the amount of water discharged into the Tokamak in the event of a tube weld failure. The device was recently tested on an antenna at Oak Ridge National Laboratory. The heat pipe design uses inclined water heat pipes with warm water condensers located outside of the plasma chamber. This approach can passively remove absorbed heat fluxes in excess of 200 W/cm 2 ;. Helium-cooled Faraday shields are also being evaluated. This approach offers the advantage of no liquid discharge into the Tokamak in the event of a tube failure. Innovative internal cooling structures based on porous metal cooling are being used to develop a helium-cooled Faraday shield structure. This approach can dissipate the high heat fluxes typical of Faraday shield applications while minimizing the required helium blower power. Preliminary analysis shows that nominal helium flow and pressure drop can sufficiently cool a Faraday shield in typical applications. Plans are in progress to fabricate and test prototype hardware based on this approach

    1991-06-01

    Nuclear Thermal Propulsion systems present unique challenges in reliability and safety. Due to the radiation incident upon all components of the propulsion system, shielding must be used to keep nuclear heating in the materials within limits; in addition, electronic control systems must be protected. This report analyzes the nuclear heating due to the radiation and the shielding required to meet the established criteria while also minimizing the shield mass. Heating rates were determined in a 2000 MWt Particle Bed Reactor (PBR) system for all materials in the interstage region, between the reactor vessel and the propellant tank, with special emphasis on meeting the silicon dose criteria. Using a Lithium Hydride/Tungsten shield, the optimum shield design was found to be: 50 cm LiH/2 cm W on the axial reflector in the reactor vessel and 50 cm LiH/2 cm W in a collar extension of the inside shield outside of the pressure vessel. Within these parameters, the radiation doses in all of the components in the interstage and lower tank regions would be within acceptable limits for mission requirements.

    1989-01-01

    Shielding is provided in a nuclear reactor to absorb the radiations emanating from the core. The energy of these radiations appear in the form of heat. Concrete which is commonly used as a shielding material in nuclear power plants must be able to withstand the temperatures and temperature gradients appearing in the shield due to this heat. High temperatures lead to dehydration of the concrete and in turn reduce the shielding effectiveness of the material. Adequate cooling needs to be provided in these shields in order to limit the maximum temperature. This paper describes a method to estimate steady state and transient temperature distribution in reactor shields. The results due to loss of coolant in the coolant tubes have been studied and presented in the paper. (author). 5 figs

    In recent years, there has been a need for compact shielding design such as self-shielding of a PET cyclotron or up-gradation of radiation machinery in existing facilities. In these cases, high performance shielding materials are needed. Concrete or polyethylene have been used for a neutron shield. However, for compact shielding, they fall short in terms of performance or durability. Therefore, a new type of neutron shielding material based on epoxy resin and colemanite has been developed. Slab attenuation experiments up to 40 cm for the new shielding material were carried out using a 252 Cf neutron source. Measurement was carried out using a REM-counter, and compared with calculation. The results show that the shielding performance is better than concrete and polyethylene mixed with 10 wt% boron oxide. From the result, we confirmed that the performance of the new material is suitable for practical use. (authors)
