The area of the town of Mailuu Suu, Kyrgyzstan, is polluted by radionuclides and heavy metals in tailing dumps and heaps resulting from the historic exploitation of uranium mines. Radioactive substances are stored in 23 tailings and 10 heaps situated along the Mailuu Suu River. The stability of many tailings is at risk. Attention is mostly directed to Tailing 3, because of its important radionuclide inventory and since threatened by the borders of a major landslide. In the frame of a European Commission-TACIS funded project, a radiological monitoring programme was set up and a radiological assessment was performed for critical group members living in the city of Mailuu Suu, located downstream the tailings, or in the village of Kara Agach, partially located on a uranium mine-waste dump. The actual radiological situation is of no immediate concern for most of the population of Mailuu Suu. The actual external exposure and exposure from radon are, respectively, around 1.2 mSv a -1 and 5 mSv a -1 , at both locations. Ingestion dose was negligible for a critical group member living at Mailuu Suu. At Kara Agach, however, under the hypothesis that all food and fodder is cultivated locally, exposure from ingestion is much higher (∼10-30 mSv a -1 ). Additional dose from irrigation with Mailuu Suu river water is small in actual conditions ( -1 ). However, there is an important possibility that, triggered by an earthquake or a landslide, (part of the) tailing(s) content may be directed to the river Mailuu Suu. In case the content of Tailing 3 is thrust to river, calculated maximum doses are 45 and 77 mSv a -1 for an adult and a child, respectively, for an assumed exposure duration of 2 years. To impede the consequences of a potential disaster, under the TACIS project different remedial options were evaluated for Tailing 3 including in situ stabilisation and tailing translocation. Also more global remedial options for the Mailuu Suu River valley were proposed (translocation

An assessment of the radioactive and chemical contamination of the water resources at the former uranium mines and processing sites of Mailuu-Suu, in Kyrgyzstan, was carried out. A large number of water samples were collected from the drinking water distribution system (DWDS), rivers, shallow aquifers and drainage water from the mine tailings. Radionuclides and trace metal contents in water from the DWDS were low in general, but were extremely high for Fe, Al and Mn. These elements were associated with the particle fractions in the water and strongly correlated with high turbidity levels. Overall, these results suggest that water from the DWDS does not represent a serious radiological hazard to the Mailuu Suu population. However, due to the high turbidities and contents of some elements, this water is not good quality drinking water. Water from artesian and dug wells were characterized by elevated levels of U (up to 10 μg/L) and some trace elements (e.g. As, Se, Cr, V and F) and anions (e.g. Cl(-), NO3(-), SO4(2-)). In two artesian wells, the WHO guideline value of 10 μg/L for As in water was exceeded. As the artesian wells are used as a source of drinking water by a large number of households, special care should be taken in order to stay within the WHO recommended guidelines. Drainage water from the mine tailings was as expected highly contaminated with many chemicals (e.g. As) and radioactive contaminants (e.g. U). The concentrations of U were more than 200 times the WHO guideline value of 30 μg/L for U in drinking water. A large variation in (234)U/(238)U isotopic ratios in water was observed, with values near equilibrium at the mine tailings and far from equilibrium outside this area (reaching ratios of 2.3 in the artesian well). This result highlights the potential use of this ratio as an indicator of the origin of U contamination in Mailuu Suu. Copyright © 2014 Elsevier Ltd. All rights reserved.

This paper describes the environmental situation in the former uranium mining and milling region of Mailuu-Suu (Kyrgyzstan), the approach to environmental remediation of the waste facilities (tailings ponds and waste dumps) and the results achieved so far. It starts with an outline of the history of the environmental remediation project which has received international attention and is seen as a pilot project for further remediation activities of former uranium mining and milling sites in the region. Apart from technical aspects, the paper draws conclusions with respect to the administrative environment, institutional capacity building and the local availability of resources needed to successfully implement a complex remediation project.

To solve the atomic problem, including the creation of an atomic weapon, one must embark on an intensive exploration and mining of radioactive raw materials, first among which uranium, together with other materials and metals. The acquisition of all these materials has thus been accompanied by the creation of a great deal of production and storage wastes and other refuse from plants, leading to many problems of protecting the environment from radioactive and other hazardous metals and materials. And so, as a result of the extensive mining and processing of radioactive and other raw materials that had been necessary for the atomic industry, in locations like Kara-Balty, Mailuu-Suu, Kavak, Kadamzhay and other places, a series of radioactive and hazardous tailings and dumps has been generated in the Kyrgyz Republic. The toxic ingredients from the dumps migrate and mix together with the ground waters that leach the tailings. However, how these waters migrate both in space and time have not been sufficiently studied; and, so, in general, we cannot forecast the propagation of these hazards. In the usual estimation of the scale of migration from uranium plants, only the total uranium content in the ground water is used. But this does not show natural or technogenic components; and it is obvious that the danger from the plants need only be characterized by the technogenic components. To solve this problem, one can employ the phenomenon where there is a natural separation in the fraction of 234 U and 238 U present in nature and as a result of technological processes. The essence of this understanding is that, as uranium transitions from solid form into a liquid, such as its dissolution in ground water, it undergoes isotope enrichment, i.e. hydrogenic uranium is enriched with 234 U compared to 238 U.The essence of this understanding is that, as uranium transitions from solid form into a liquid, such as its dissolution in ground water, it undergoes isotope enrichment, i

Full text: In the end of XX c. in connection with increased texnogenium of biosphere accompanying wide application of mineral fertilizers, accumulation in environment wastes of a mining industry, household wastes and other, technogenium biogeochemical provinces and new associations of chemical elements arise. It is known, that sharp deficiency or the surplus in environment of biologically active elements results in diseases of animals, plants and a man. On the territory of Kyrgyzstan and other countries biogeochemical provinces with deficiency and surplus I, F, Cu, Cu, V, Ca, Sr, Se, U and Hg are investigated. The doctrine about biogeochemical provinces finds practical realization in medicine and agriculture (preventive maintenance of endemical diseases, synthesis of medicines, manufacture of micro fertilizers etc.). Selection of samples of soil, natural waters and plants carried out by a way of platforms on the certain routes with the account of landscape-geochemical and meteorological conditions. Processing of samples carried out in biogeochemistry laboratory of an environment GEOCHI of RAS and Biology-soil institute NAS of KR with use of soil and geological cards at an advice of the geologists and soil scientists of Kyrgyzstan. Concentration of triselementis was being by AAC, Spectrofluorimetrical and etc. methods. During operation of a uranium deposit Mailuu-Suu (1946-1968 years) more than 10 thousand tons of uranium were extracted. According to the scientific geologists and geochemists, radioactive wastes in the given site, are quantitatively equivalent to size of the extracted uranium. In tail-depository the huge weights of residual uranium and it long-lived of isotopes (Th-230, Ra-226 etc.), hence, radio-activity tail-depositories will be kept long. Now condition of these damps and storehouses contains in a so pitiable condition, that radioactive wastes, heavy metals and the toxic substances pollute an environment. And, most dangerous sites are in landslide

Full Text Available Kyrgyzstan is one of the 27 high multidrug-resistant tuberculosis (MDR-TB burden countries listed by the WHO. In 2012, Médecins Sans Frontières (MSF started a drug-resistant tuberculosis (DR-TB project in Kara Suu District. A qualitative study was undertaken to understand the perception of TB and DR-TB in order to improve the effectiveness and acceptance of the MSF intervention and to support advocacy strategies for an ambulatory model of care.This paper reports findings from 63 interviews with patients, caregivers, health care providers and members of communities. Data was analysed using a qualitative content analysis. Validation was ensured by triangulation and a 'thick' description of the research context, and by presenting deviant cases.Findings show that the general population interprets TB as the 'lungs having a cold' or as a 'family disease' rather than as an infectious illness. From their perspective, individuals facing poor living conditions are more likely to get TB than wealthier people. Vulnerable groups such as drug and alcohol users, homeless persons, ethnic minorities and young women face barriers in accessing health care. As also reported in other publications, TB is highly stigmatised and possible side effects of the long treatment course are seen as unbearable; therefore, people only turn to public health care quite late. Most patients prefer ambulatory treatment because of the much needed emotional support from their social environment, which positively impacts treatment concordance. Health care providers favour inpatient treatment only for a better monitoring of side effects. Health staff increasingly acknowledges the central role they play in supporting DR-TB patients, and the importance of assuming a more empathic attitude.Health promotion activities should aim at improving knowledge on TB and DR-TB, reducing stigma, and fostering the inclusion of vulnerable populations. Health seeking delays and adherence problems will

Full text: Within the framework of the International Cooperation Program in the sphere of the transboundary monitoring of the rivers between the Republics of Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan, and the United States of America ( N avruz , ISTC KR-850 Project), in addition, in the Kyrgyz Republic, the isotopic content (isotopic ratio of 234 U/ 238 U=γ ), and the uranium content (CU) in the waters was measured. The isotopic ratio 234 U/ 238 U=γ of the waters of the rivers Naryn and Kara-Daria basins has no anomalous values of 234 U/ 238 U, which indicates the absence of the man-caused uranium in these rivers. The results of determination of the activity ratio of 234 U/ 238 U and uranium content in the Mailuu-Suu river basin are of great interest. In the upper reaches of the Mailuu-Suu river the uranium content is 0.4 10 -6 g/l (0.8 10 -6 g/l in the flood period), in Mailuu-Suu town (after the tailing dump) - (3 †4) 10 -6 g/l, i.e. this value is an order of magnitude higher, and at the border with Uzbekistan - 1.8 ·10 -6 g/l (3.2 ·10 -6 g/l in the period of flooding), which is lower as compared with the town. Correspondently, there are changes in the activity ratio from 1.39 (in the upper reaches of the river) to 1.05 (in the town), and 1.32 (1.12 during the flood period) at the border with Uzbekistan. This situation indicates, first, the enrichment of the waters of the rivers with the man-caused uranium ( γ=1), and its subsequent sorption along the river stream. The obtained results indicate the absence of the man-caused uranium in the whole stream of the Naryn and Kara-Daria rivers on the territory of the Kyrgyz Republic, and lack of noticeable contamination of the waters of the Mailuu-Suu river with the man-caused uranium from the tailing dumps of the Western Mining-Chemical Plant (WMCP, Mailuu-Suu). It also should be noted that the share of the man-caused uranium, transported to Uzbekistan by the Mailuu-Suu river does not exceed 20-30%, and

2007-01-01
The areas of our study are uranium mining areas (with tails and dumps) Min-Kush, Kadji-Sai, Mailuu-Suu. These areas situated in different parts of Tien-Shan region. We study the content (and correlations among): level of uranium in environment, immune function and level, level in human teeth. It has been found: content of uranium in river water under tails about 2,0x10-5 gm/litter, and high level in drinking water too 2,0-4,0. Drying grass and flowers uranium content was 0,04-0,51x10-5 gm/gm, most high content were in Tacniatherum crinitum and Atgilops triuncialis. Lams tissues contain 0,005-2,44 mg/g in Min-Kush, 0,03-0,107, in Mailuu-Suu, and 0,001-0,048 mg/g in Kadji-Sai. Human teeth uranium content (Mailuu-Suu): in milk-teeth 0,481x10-6 gm/gm, in former miners 0,7684x10-6 gm/gm. Inhabitants of the area, which not working in uranium industry have 0,6876x10-6 gm/gm. There was low level of immune function (lymphocytes, IgI globulin, etc) in all three regions (in child, in adults, in uranium-mining worked people). There is no doubt of the positive correlations of uranium pollution of water (by underground infiltration from tails) on one hand and, on the other hand - a) grass, b) lambs body, c) human teeth, d) human immune function. Levels of uranium in teeth strictly depend on time of mining contact. (author)

Myanmar is undergoing a comprehensive political transition. In April this year the first democratically elected government in six decades came into power under the leadership of NLD, the pro-democracy party headed by Aung San Suu Kyi. The largest peace conference in the country’s history was held...... in early September, and Myanmar again made the international headlines a week later when Kofi Annan visited the country to head a commission for addressing communal violence. These national events are crucial to the democratization process in Myanmar and for ending the almost seven decades of civil war....... However, often overlooked in this larger picture of transition is the state of local democracy, including village level governance and everyday state-citizen engagements. Political changes at this level are equally crucial for the wider democratization process. This roundtable summary discusses the 2016...

Health conditions among workers who participated in the cleanup of the Chernobyl accident
International Nuclear Information System (INIS)
Kamarli, Z.; Abdulina, A.
1996-01-01
People who took part in the Chernobyl accident cleanup have been registered upon their return to Kyrgyzstan since 1991, and their children since 1992. Later, citizens affected by the Semipalatinsk and Chelyabinsk contamination incidents were included for registration and health care purposes. The effects of the nuclear waste depositories in the Mailuu-Suu region were examined with the assistance of the Kansas University Medical Center (United States of America). All these investigations of affected people indicated apparent increases in a number of symptoms and illnesses when compared to the rest of the population.

Health as a bridge to peace and trust in Myanmar: The 21st Century Panglong Conference.
Tang, Kun; Zhao, Yingxi
2017-06-28
The twenty-first Century Panglong Conference, proposed by Aung San Suu Kyi and her National League for Democracy, has concluded with unsatisfactory results. This five-day conference attracted global attention and wide endorsements from the United Nations and many other key stakeholders. The broad framework of the peace dialogue included various social and economic issues. However, the implication of the conference on the health system strengthening efforts in ethnic areas was largely unknown. Although a "convergence model" was proposed by organizations in Thai-Myanmar borders as a roadmap for integrations of the national and ethnic health systems years ago, the genuine bottlenecks beneath have not been addressed. This commentary discussed the Panglong Conference and its implication for the health systems in ethnic regions, as well as the bottlenecks of a "peace process" in health sector. It outlined a few key steps to achieve health system convergence between national and ethnic health systems, the outcome of which will not only improve the health status of the ethnic regions, but also help strengthen mutual trust and understanding among peoples, as a powerful bridge for peace.

Full Text Available W pracy przedstawiono wyniki badań wytrzymałości resztkowej gruntów spoistych pochodzących z terenów osuwiskowych okolic Szymbarku k. Gorlic. Badania przeprowadzone zostały w aparacie bezpośredniego ścinania na próbkach o przekroju 60 × 60 mm. Zastosowano dwie prędkości ścinania 0,05 i 0,1 mm • min–1, każda próbka była ścinana sześciokrotnie, a zakres poziomych odkształceń próbek wynosił 20%. Badania wykazały, że resztkowa wytrzymałość na ścinanie wzdłuż wytworzonej płaszczyzny osłabienia stanowi 52–78% jego wytrzymałości maksymalnej, a do wytworzenia płaszczyzny osłabienia niezbędne jest co najmniej 5-krotne ścinanie próbki. Wpływ prędkości ścinania miał niejednoznaczny wpływ na otrzymane wartości wytrzymałości resztkowej. Wykazano, że stosując do uzyskanych wyników badań liniową interpretację równania Coulomba-Mohra otrzymano niezerowe wartości spójności resztkowej. W związku z tym dla ograniczenia wpływu tego parametru na ocenę stateczności należałoby stosować nieliniową obwiednię wytrzymałościową, do której opisu można zastosować przedstawione w pracy równanie Lade.

This paper interprets the origin of several of the largest hummocky landform assemblages in the Alai Valley, Northern Pamir - a formerly glaciated intermontane depression. The vast hummocky deposits in the Koman-Suu and Achik-Tash river catchments are found to be of two contrasting modes of formation: glacial hummocks deposited during Koman and Lenin Glaciers withdraw and avalanche hummocks produced during catastrophic Koman and Lenin rock avalanches. The origins of the deposits we assessed through remote and field-based geomorphological mapping, as well as sedimentological investigations, which included clast analysis and the identification of micro-scale agglomerates indicative of rock avalanche emplacement. Both the Koman and Lenin rock avalanches were large, catastrophic events (with run-outs of 34 and 24 km, respectively, and a volume over 1 × 109 m3 each) that occurred subsequent to glacier withdrawal from the area. The complex conditions on the moment of the rock avalanche emplacement promoted unusual deposits geomorphology and extensive run-outs. The landslide landforms formed over the pre-existing glacial hummocks and fluvial deposits, and are geomorphologically and sedimentologically distinct from the larger glacial hummocks. The reconstruction of this sequence of events has implications for how hummock dating should be interpreted. This research illustrates large scale catastrophic landsliding in the glacial environment, and adds to the ongoing debate about the misidentification of rock avalanche deposits as of glacial origin, and their relevance to palaeoclimatological and palaeoseismological reconstructions.

We examined the influence of dynamic thermal treatment (variation of cooling/heating rates) on the polymorphic crystallization and transformation pathways of 1-palmitoyl-2,3-dioleoyl glycerol (POO), 1-stearoyl-2,3-dioleoyl glycerol (SOO), and 1-palmitoyl-2-oleoyl-3-linoleoyl glycerol (POL), which are major saturated-unsaturated-unsaturated (SUU) triacylglycerols (TAGs) of vegetable oils and animal fats (e.g., palm oil, olive oil, and Iberian ham fat). Using mainly a combination of differential scanning calorimetry (DSC) and synchrotron radiation X-ray diffraction (SR-XRD), we analyzed the polymorphic behavior of TAGs when high (15°Cmin -1 ), intermediate (2°Cmin -1 ), and low (0.5°Cmin -1 ) cooling and heating rates were applied. Multiple polymorphic forms were detected in POO, SOO, and POL (sub-α, α, β' 2 , and β' 1 ). Transient disordered phases, defined as kinetic liquid crystal (KLC) phases, were determined in POO and SOO for the first time. The results demonstrated that more stable forms were directly obtained from the melt by decreasing the cooling rates, whereas less stable forms predominated at high cooling rates, as confirmed in our previous work. Regarding heating rate variation, we confirmed that the nature of the polymorphic transformations observed (solid-state, transformation through KLC phase, or melt-mediation) depended largely on the heating rate. These results were discussed considering the activation energies involved in each process and compared with previous studies on TAGs with different saturated-unsaturated structures (1,3-dioleoyl-2-palmitoylglycerol, 1,3-dipalmitoyl-2-oleoyl-glycerol, trioleoyl glycerol, and 1,2-dioleoyl-3-linoleoyl glycerol).

Full Text Available Ostre uszkodzenie nerek (acute kidney injury, AKI jest rozpoznawane w oparciu o stężenie kreatyniny w surowicy i upośledzenie filtracji kłębuszkowej (glomerular filtration rate, GFR. AKI, które zastąpiło w ostatnich latach termin ostra niewydolność nerek, jest rozpoznawane między innymi u pacjentów po operacjach kardiochirurgicznych, w wyniku nefrotoksycznego uszkodzenia radiokontrastem podczas zabiegów naczyniowych i badań obrazowych, u pacjentów oddziałów intensywnej terapii, we wstrząsie septycznym. Stężenie surowiczej kreatyniny jest ciągle głównym testem diagnostycznym, chociaż zmienia się w przebiegu AKI później niż GFR, który stanowi dokładniejszy wskaźnik czynności nerek. Użyteczność stężenia kreatyniny jako obiektywnego parametru jest jednak ograniczona, ponieważ zależy ono od wielu czynników, w tym od stopnia nawodnienia, diety, masy ciała, masy mięśniowej, wieku, płci, stosowanych leków. Nowe badania zaprezentowały inne, bardziej użyteczne laboratoryjne markery AKI, możliwe do oznaczenia w surowicy i/lub w moczu. Należą do nich m.in. cystatyna C, NGAL, KIM-1, L-FABP i IL-18. Nowe biomarkery stwarzają większe możliwości we wczesnym wykrywaniu AKI, a także mogą określać stopień uszkodzenia nerek w przebiegu AKI. Mogą być również przydatne w prognozowaniu zagrożenia przewlekłą chorobą nerek (PChN w wyniku AKI lub z innych przyczyn. Celem opracowania jest przedstawienie przeglądu aktualnych doniesień dotyczących zastosowania nowych biomarkerów we wczesnym wykrywaniu AKI oraz progresji do PChN.

Effects of Climate and Social Change on Pasture Productivity and Area in the Alay Valley, Kyrgyzstan
Zhang, L.; Smithwick, E. A. H.
2017-12-01
The high elevation Alay Valley, located in the central Asian country of Kyrgyzstan, has experienced substantial socio-political and environmental changes in recent decades, resulting from the collapse of the Soviet Union and an increase in average annual temperature from 1.8 C to 2.7 C between 1990 and 2014. However, the consequences of these changes on pastureland productivity and area has not been previously assessed, despite the critical cultural and economic importance of pasturelands for sustaining livelihoods in this region. We assessed spatial and temporal patterns of soil moisture, pasture productivity and pasture area in the Alay Valley. Supervised classification was performed on Landsat imagery over the study region to distinguish pastures and agricultural land in order to relate changes in soil moisture to specific land classes. Root Zone Soil Moisture (RZSM) was estimated between May 2015 and June 2017 from Soil Moisture Active Passive L4 RZSM product. Average monthly NDVI for 2016 was calculated to obtain seasonal patterns in productivity of the pasturelands in the region. Results show that annual RZSM trends closely matched those of precipitation, as RZSM peaks during May (the wettest month) and decreases during the dry summer. The NDVI trend is also notable as it peaks very early in June before declining due to limited precipitation and grazing practices. There has been a sharp increase in pasturelands encompassing the bank of the Kyzyl Suu river from 1993 to 2016. Likely due to turmoil from collapse of the USSR, the area of pasturelands decreased slightly from 59.98 to 55.99 km^2 from 1993-1994, corresponding with a decline in livestock count and GDP per capita. The area of pasturelands has since recovered and is hovering around 104.47 - 107.95 km^2 between 2009-2016. Overall results highlight both sensitivity and resilience of high elevation pasture to coupled socio-environmental drivers.

Full Text Available Wstęp. W Polsce znaczny odsetek populacji pozyskuje wodę pitną ze studni kopanych, podatnych na zanieczyszczenia przemysłowe i rolnicze. Woda pochodząca z tzw. prywatnych ujęć wodnych, zgodnie z polskim prawodawstwem, nie podlega jednak ustawowej kontroli, a jej spo- żywanie naraża konsumentów na negatywne skutki zdrowotne. Celem pracy było oszacowanie wybranych parametrów fizykochemicznych wody pitnej ze studni kopanych oraz odniesienie uzyskanych wyników do norm ujętych w rozporządzeniu ministra zdrowia. Materiał i metody. W przeprowadzonych analizach 36 próbek wody studziennej z terenu gminy Chmielnik, zawartość azotanów (III i jonu amonowego badano za pomocą fotometru, odczyn i przewodność elektrolityczną miernikiem wieloparametrowym, mętność za pomocą turbidymetru, zaś stężenie chlorków oznaczono metodą miareczkową. Wyniki. Dla badanych parametrów chemicznych, tj. azotanów (III, chlorków i jonu amonowego nie stwierdzono przekroczeń dopuszczalnych norm, podobnie jak dla parametru fizycznego, tj. przewodności elektrolitycznej. Ponadnormatywne wartości odnotowano natomiast dla dwóch parametrów fizycznych, tj. odczynu (2 próbki i mętności (33 próbki. Wnioski. Wodę z badanych studni kopanych można określić jako bezpieczną dla konsumentów pod względem badanych parametrów chemicznych, dla których spodziewano się przekroczeń dopuszczalnych norm w związku z terminem poboru. Problem ponadnormatywnych wartości mętności dla większości kontrolowanych studni może być rozwiązany poprzez wprowadzenie prostych metod uzdatniania, natomiast wprowadzenie regularnych badań wszystkich parametrów jakości wody pitnej pozwoliłoby ustalić, czy przekroczone normy dla odczynu wiążą się z niedopuszczalnymi stężeniami wskaźników chemicznych, które nie były badane w niniejszej pracy.

weapons' arsenal. Yet, the newly independent Kyrgyz Republic was left alone with an enormous amount of uranium waste, which was extracted on the Kyrgyz territory to produce these nuclear armaments. As a consequence of the Soviet policy, uranium waste storage sites represent a direct danger to the environment of present-day Kyrgyzstan. Therefore, Russia as the official successor of the Soviet Empire should help the Kyrgyz Republic to deal with this costly and extensive problem. These environmental issues serve as a basis for the given work. In turn, research will be primarily concentrated on several the most problematic radioactive waste storage sites, namely, the Mailuu-Suu, Kadji-Say, Kara-Balta, and Ak-Tuz uranium storages. Today, Kyrgyzstan has 50 radioactive waste storage sites, located throughout its territory and contained altogether about 300 million tons of wastes. In general, it could be suggested that the financial responsibility could be delegated to the Kyrgyz government; the Central Asian Community; Russia. It is clear with the first instance, the Kyrgyz government, as it ought to deal with the environmental problems of its country. The situation is more sophisticated and arguable in terms of second and third instance, namely, the Central Asian Community and, particularly, Russia. This paper is designed to prove not only the necessity for their involvement, but rather their responsibility for the present-day situation with the Kyrgyz storage sites. As regards the other Central Asian States, it is in their interests since they are under immediate threat of being affected. Concerning Russia, it is rather a moral right to demand its assistance than a legally legitimate one. All information, related to uranium, its extraction and further utilization was totally classified and only revealed after the Soviet Union's dissolution. Only in 1994 did the Kyrgyz public become acquainted with the truly poor environmental conditions of the newly fledged Republic. Yet, no

(VI) sorption on four montmorillonite-standard, which are distinguished by the cationic composition of the octahedral sheet, provided further evidence on the mechanism of uranium(VI) sorption on montmorillonit. The uranium(VI) sorption was found to be controlled by the cationic composition of the octahedral sheet and by the dissolution rate of montmorillonite. Higher Mg contents in the octahedral sheet enhance the dissolution kinetics of Montmorillonite and thus lower uranium(VI) sorption with time and vice versa. In addition to Al and Fe octahedron, Mg octahedron contributes to the sorption of uranium(VI) (here 20 up to 50 % depending on Mg content in Montmorillonite). These observations allowed to propose a model for the mechanism of uranium(VI) sorption on the edge surface of montmorillonite. At lower octahedral Mg contents (here SWy- and STx-montmorillonites), at which the distance between Mg octahedra becomes larger, uranium(VI) binds monodentately to AlAl-OH, AlFe-OH, AlMg-OH, FeFe-OH, and FeMg-OH pairs and the Mg octahedra contribute up to approximately 20 % to the sorption of uranium(VI). At high Mg contents in the octahedral sheet, where the distance between Mg octahedra becomes small and MgMg-OH pairs can occur, uranium(VI) forms monodentate surface complexes with AlAl-OH, AlFe-OH, AlMg-OH, FeFe-OH, FeMg-OH, and MgMg-OH pairs and the Mg octahedra can even stronger contribute to uranium(VI) sorption (up to about 50 %). The second focus of this work concerned the environmental analytics of uranium. In this regard, extensive investigations of environmental samples from tailings disposal sites near Mailuu-Suu city (Kyrgyzstan) were carried out. Previous radiological examinations in Mailuu-Suu showed that uranium can migrate from tailings as a result of rain events to the ground water and river water and eventually to the foods [Vandenhove et al., 2006]. Therefore, it was very important to investigate, uranium speciation in water samples and the processes which controlling

Damage-reducing measures to manage flood risks in a changing climate
Kreibich, Heidi; Bubeck, Philip; Van Vliet, Mathijs; De Moel, Hans
2014-05-01
Damage due to floods has increased during the last few decades, and further increases are expected in several regions due to climate change and a growing vulnerability. To address the projected increase in flood risk, a combination of structural and non-structural flood risk mitigation measures is considered as a promising adaptation strategy. Such a combination takes into account that flood defence systems may fail, and prepare for unexpected crisis situations via land-use planning, building construction, evacuation and disaster response. Non-structural flood risk mitigation measures like shielding with water shutters or sand bags, building fortification or safeguarding of hazardous substances are often voluntary: they demand self-dependent action by the population at risk (Bubeck et al. 2012; 2013). It is believed that these measures are especially effective in areas with frequent flood events and low flood water levels, but some types of measures showed a significant damage-reducing effect also during extreme flood events, such as the Elbe River flood in August 2002 in Germany (Kreibich et al. 2005; 2011). Despite the growing importance of damage-reducing measures, information is still scarce about factors that motivate people to undertake such measures, the state of implementation of various non-structural measures in different countries and their damage reducing effects. Thus, we collected information and undertook an international review about this topic in the framework of the Dutch KfC project "Climate proof flood risk management". The contribution will present an overview about the available information on damage-reducing measures and draw conclusions for practical flood risk management in a changing climate.

Introduction of new advanced electrical connections into a transmission grid reduces the capacity of existing overhead lines (OHLs). At the same time, designing & building of new OHLs and substations involves considerable technical, environmental and economical problems. The authors propose a concept of the multi-objective optimization for selection of transmission line routes, towers (their type, placement and geometry), of conductors, insulators, dampers, earthing and lightning protection systems, span lengths, etc.. The optimization is organized in five stages. At the first and second stages a search for optimum solutions is performed along with determination of the main impacting factors. The next two stages present a two-objective optimization based on Pareto's approach. At the last stage (exemplified by a case study), the probability of the restriction removal conditions is assessed, and preventive measures are identified. The presented approach uses a real line design and is intended for minimizing the total invested capital and maximizing the net present value. In the framework of this approach 20 alternatives have been elaborated, which can successfully be applied in the cases described in the paper.

Solution of atomic problem, which comprises atomic weapon creation, required intensive exploration and extraction of radioactive raw material, uranium ores in the first place, as well as other important metals for this purpose. Practical realization of these problems led to formation of many storages of wastes (tail storages) and dumps of mining production. In this connection the problems of the environmental protection from contamination by radioactive and other unhealthy metals appeared. As a result of mining and processing of radioactive and other raw material, which are necessary in atomic industry, a series of tail storages and dumps appeared in the Kyrgyz Republic. The largest of them are the Kara-Balty, Mailuu-Suu, Kavak, Kadamjai and other tail storages of uranium production. Toxic ingredients of the tail storages migrate together with the natural waters. However the regularities of their migration in space and time are studied insufficiently. By this reason it is almost impossible forecasting radiative and other ecological hazard. As an assessment of the measure of migration from territories of uranium plants only summarized the content of the uranium in underground waters, without natural and technogenic (man-caused) component separation is used at present time, though it is obvious, that just a technogenic component must characterize hazard. For solving this problem the discovery 'Phenomenon of uranium-234 and uranium-238 natural separation' and different degree of 2 34U and 2 38U fractioning in natural conditions and during technological processes were used. Essence of the discovery consists in that at transition of uranium from solid uranium-containing formations in liquids (comprising natural waters), which do not dissolve these formations, the enrichment of isotopic mixture by uranium-234 occurs. As a result of this natural waters and hydrogenic uranium derived from them have a surplus of 2 34U toward 2 38U. In technological cycle when deriving the

covered ground (0,20 sm) the contents of uranium about from 1,1 up to 2,6x10-6 g/g, and with depth it is increased a few - to 3,0x10-6 g/g. there is more concentration of uranium in the average zone of Uranium deposits, where has the contents of uranium in the upper horizon of a soil equally 4,2x10-6 g/g, and in the bottom of horizon, on depth of 40-60 sm consist - 35,0x10-6 g/g or in 8,3 times above. According to some authors quantity of uranium in waters of the rivers Tone, Ae-Suu in hollow of Issyk-Kul makes 5,6x10-6 g/l, and in river Jergalan about (depend on seasonally and places of selection) from 2,8x10-6 to 1x10-5 g/l i.e. the main waters of wells and the rivers a hollow of Issyk-Kul contain in 10, and in some cases it is in 100 times more uranium, than water from black earth and not from black earth zones. On the surface of uranium tail deposits founded 10 sorts of plants of desert type: Ulmus pinnato-ramosa, Elaeagnus songorica, Caragana Turfanica, Peganum harmala, Akantholimon alatavicum, Natraria sibirica, Clematis songorica... The contents of uranium in the listed plants was small and changed about 0.02-0.31x10-6 g/g at coefficient of enrich is - from 1,0 to 15,5 and coefficient of discrimination is - from 17,8 to 240,0. Growing of plants in the environment with the high concentration of uranium not only is accompanied by change of theirs bioproductivity but also causes of morphological variability. The infringement of pigmentation of a flower at various sorts of plants is most often shown in area of Issyk Kul. The Astragalus borodinii is has morphological variability of splitting of a sheet plate. The Peganum garmala and Potentilla argentea - instead of usual 5 petals have 6-7 and their bifurcation. But other plants are intensive growing and developing (Caragana, Scutellaria, Peganum, and Peganum harmala).

Full Text Available Rengdamas spausdinti fotokopinį Mikalojaus Daukšos 1595 m. katekizmo (toliau – DK leidimą, susidūriau su keliomis nevienodai interpretuojamomis teksto glosomis. Išspausdinto fotokopinio leidimo įžanginiame straipsnyje „1595 m. katekizmas ir jo leidimai“ mėginau tas glosas aiškinti. Tačiau beskaitant jau išspausdintą tą leidimą kilo ir naujų minčių dėl vienos tokios glosos, būtent dėl Mudrusiaks ißmintingas, esančios leidinio 134 puslapio paraštėje.Ši glosa prirašyta ne prie tos teksto dalies, kurioje reiškiamas mokinio (= Mokitinio, Mo atsakymas į mokytojo (= Mistro, M klausimą „Kaſg yra Jėzus Christus?“, – „Yra ſunús Diewo teip galis / teip geras teip ißmintingas... [mano pabraukta. – J. P.], o ties minėtu klausimu kaip šio būdvardžio sinoniminis variantas (lenkiškojo originalo mądry atitikmuo.Nei 1886 m. Eduardo Volterio paskelbtame DK leidime, nei 1929 m. Ernsto Sittigo volteriškojo leidimo perspaude minėta glosa nebuvo komentuojama. Bene pirmasis ją, kaip būdvardžio išmintingas paralelizmą, suskaidęs į du žodžius – mudru ir seks, bet prie jų skliausteliuose prirašęs klaustuką (?, savo straipsnyje „Leksiniai paralelizmai Daukšos katekizmo (1595 kalboje“ bandė aiškinti Jonas Kruopas.

mezi závodníky s různou výkonností, ale i uvnitř skupin se srovnatelnou délkou skoku. CÍLE: Cílem studie bylo porovnat provedení zahájení přechodové fáze skoku mezi skupinami závodníků v severské kombinaci s různou výkonností. Určit rozdíly v provedení této fáze skoku mezi závodníky v severské kombinaci a ve skoku na lyžích. METODIKA: Odrazová a přechodová fáze skoku na můstku HS-134 m při závodech MS v klasickém lyžování v Liberci v r. 2009 byla zaznamenána s využitím tří kamer (50 Hz. Kamery byly umístěny tak, že jejich optické osy byly kolmé na rovinu pohybu závodníků. Vybrané body na těle a na lyžích závodníků byly vyhodnoceny manuálně. Ze souřadnic těchto bodů jsme určili základní úhlové a rychlostní charakteristiky pro polohu segmentů a lyží. Ze všech startujících závodníků v severské kombinaci jsme vybrali a porovnali skupiny, které dosáhly nejlepší (B, průměrné (M a nejkratší (P délky skoku. VÝSLEDKY: Nájezdová rychlost byla při porovnání skupiny závodníků severské kombinace (NC a skoku na lyžích (SJ významně vyšší u skupiny NC (p < 0,01. Skupina SJ měla na hraně můstku větší posun těla dopředu (p < 0,05. Velikost úhlové rychlosti v kolenním kloubu v úseku 0 až 5 m za hranou můstku byla vyšší u skupiny SJ (p < 0,05. Při porovnání skupin nejlepších závodníků v obou disciplínách byl nalezen rozdíl v poloze bérců na hraně můstku i v celém úseku za hranou. Skupina SJ se vyznačovala větším posunem dolních končetin dopředu (hrana, p < 0,05; 5 m za hranou, p < 0,01, úhlová rychlost v kolenním kloubu byla vyšší. V tomto parametru jsme také zjistili rozdíl mezi skupinami závodníků s průměrnou výkonností, s větší úhlovou rychlostí u skupiny SJ (p < 0,05. ZÁVĚRY: Závodníci ve skoku na lyžích mají ve sledovaném úseku za hranou můstku výhodnější aerodynamickou polohu těla, s v

żdej cechy (współrzędnej) zostaje przyporządkowany punkt odniesienia reprezentujący tą cechę. Czyli przy danych 7-wymiarowych umieszczamy na płaszczyźnie 7 takich punktów odniesienia reprezentujących poszczególne współrzędne. Rozkład punktów reprezentujących przedstawiane wielowymiarowe dane odzwierciedla relacje pomiędzy tymi danymi a cechami. Im bardziej i-ta cecha występuje w danym obiekcie (czyli i-ta współrzędna ma większą wartość), tym bliżej powinien leżeć punkt reprezentujący dany obiekt względem punktu odniesienia reprezentującego i-tą cechę (współrzędną). W ten sposób każdy punkt odniesienia reprezentujący daną cechę, dzieli płaszczyznę na obszary bardziej oraz mniej zależne od cechy nr i (mniej oraz bardziej odległe od punktu odniesienia reprezentującego i-tą cechę). Dokładny opis algorytmu przedstawiono w podrozdziale 3 artykułu. Za pomocą omawianej metody dokonano wizualizacji danych dotyczących przedstawionych typów węgla. Uzyskane rezultaty przedstawiono na rysunkach 1-9. Widoki te pokazują sposób, w jaki 7-wymiarowe dane zostają przekształcone przy pomocy mapy odniesienia do dwóch wymiarów. Algorytm wizualizacji przy użyciu mapy odniesienia działa tak by pomimo znacznej redukcji liczby wymiarów, w jak największym stopniu odległości pomiędzy punktem reprezentującym konkretny wektor danych a punktami odniesienia zależały od współrzędnych tego wektora danych. W ten sposób na ekranie 2-wymiarowym, możemy zobaczyć istotne cechy danych 7-wymiarowych. Na rysunkach 1-4 widać, w jaki sposób wzrasta grupowanie punktów reprezentujących trzy różne klasy węgla (31, 34.2 oraz 35) wraz ze wzrostem parametru ITER. Widać, że punkty będące obrazami danych reprezentujących te same klasy węgla zaczynają zajmować osobne podobszary oraz zaczynają się grupować. Jednak w niektórych częściach przestrzeni obrazy punktów reprezentujących różne klasy węgla zachodzą na siebie. Przez
