Full Text Available Coastal dynamics monitoring on the key areas of oil and gas development at the Barents and Kara Seas has been carried out by Laboratory of Geoecology of the North at the Faculty of Geography (Lomonosov Moscow State University together with Zubov State Oceanographic Institute (Russian Federal Service for Hydrometeorology and Environmental Monitoring for more than 30 years. During this period, an up-to-date monitoring technology, which includes direct field observations, remote sensing and numerical methods, has been developed. The results of such investigations are analyzed on the example of the Ural coast of Baydaratskaya Bay, Kara Sea. The dynamics of thermal-abrasion coasts are directly linked with climate and sea ice extent change. A description of how the wind-wave energy flux and the duration of the ice-free period affect the coastal line retreat is provided, along with a method of the wind-wave energy assessment and its results for the Kara Sea region. We have also evaluated the influence of local anthropogenic impacts on the dynamics of the Arctic coasts. As a result, methods of investigations necessary for obtaining the parameters required for the forecast of the retreat of thermoabrasional coasts have been developed.

The urinary excretion of purine derivatives (PD) was measured in four Yerli Kara bulls in two experiments, a fasting experiment lasting for 7 days and the other , where animals were given a diet containing 30% wheat straw and 70% compounded feed at four levels of intake (40,60,80 and 95% of voluntary feed intake). In the second experiment, which was carried out according to a 4x4 Latin Square design, four animals receiving 60 and 95% levels of intake were also given a single injection of 8- ''1''4C - uric acid via a jugular catheter. In Addition to the above two experiments the activity of xanthine oxidase and uricase in plasma, liver and intestinal mucosa obtained from Yerli Kara cattle was also determined.In the first experiment,fasting PD excretion averaged 0.691 (±0.053) mmol/kgW''0''.''7''5/d. Glomerular filtration rate GFR), tubular load and net re-absorption of allantoin between pre fasting and fasting were statistically significant (P<0.05). In the second experiment the recovery of injected 8 - ''1''4C - uric acid as total PD was 72.5 and 89.9% for 60 and 95% feeding levels, respectively. The average recovery was 81%. Plasma kinetics measured by 8 - ''1''4C - uric acid indicated that the total compartment pool size was 214.0 (±43.8) and 250.3 L (±29.5) for 60 and 95% feeding levels, respectively. GFR, tubular load and net re-absorption of uric acid and allantoin were not affected by feed intake. The allantoin : PD molar ratios changed between 0.78 to 0.93 for the four levels feed intake. There were significant correlations between PD excretion (expressed as mmol/d and μmol/kg W''0''.''7''5/d) and DDMI (kg/d and kg/kg W''0''.''7''5/d) and DOMI (kg/d)(r=0.99, P<0.01). The rate of PD excretion as a linear function of feed intake was 16.4 mmol/kg W''0''.''7''5 DDMI, 19.8 mmol/kg DDMI and 22.7 mmol/kg DOMI. Xanthine oxidase and uricase activities were; 1.34 (±0.72) and .44 (±0.05) and 0.13 (±0.03) and 0.08 (±0.03) unit/g fresh tissue in liver and

The largest inventory of radioactive materials dumped in the Kara Sea by the former Soviet Union comes from the spent nuclear fuel (SNF) of seven marine reactors, the current (1994) inventory of which makes a total of approximately 4.7x10 15 Bq. In progressing its work for the International Arctic Seas Assessment Project, under the auspices of the International Atomic Energy Agency, the Source Term Working Group has analysed the Source Term and subsequently developed a number of model scenarios for the potential release patterns of radionuclides into the Kara Sea from the SNF and activated components dumped within the marine reactors.These models are based on the present and future conditions of the barrier materials and their configuration within the dumped objects. They account for progressive corrosion of the outer and inner steel barriers, breakdown of the organic fillers, and degradation and leaching from the SNFs. Annual release rates are predicted to four thousand years into the future. 5 refs., 1 fig., 1 tab

The activities of several nuclear reprocessing plants (Siberian Chemical Combine (SCC) and Mining, Chemical Combine (MCC) and Mayak Production Association (Mayak)) that are placed in the watersheds of large Siberian rivers Ob' and Yenisey may potentially cause contamination of the Arctic Ocean. An assessment of the levels of radionuclide discharges into the Kara Sea from existing and potential sources of techno-genic radioactivity, located within the watershed of the Ob' and Yenisey rivers is presented. In frame of EU INCO-COPERNICUS project RADARC a linked chain of 1D river model RIVTOX and 3D estuary model THREETOX was used to simulate impact of the previous and potential releases from the nuclear installations in the basins of Ob' and Yenisey rivers on radioactive contamination of the rivers and the Kara Sea. The RIVTOX includes the one-dimensional model of river hydraulics, suspended sediment and radionuclide transport in river channels. THREETOX includes a set of submodels: a hydrodynamics sub-model, ice dynamics-thermodynamics sub-model, suspended sediment transport and radionuclide transport submodels. The radionuclide transport model simulate processes in water, suspended sediments and in bottom sediments. These models were adapted to the Ob' river path from Mayak and SCC and Yenisey River from MCC. The simulations of 90 Sr and 137 Cs contamination for the period 1949-1994 were carried out for the Ob' and period 1959-1994 for the Yenisey. The use of model chain allowed to reconstruct contamination of water and sediments along the river path to estimate fluxes into the Kara Sea. It was shown strong initial contamination in early 50's the sediments in the Ob' were sources for secondary contamination of river and estuary. Based on chosen realistic scenarios, simulations have been performed in order to assess the potential risk of contamination from existing and potential sources of radionuclides into the Kara Sea through the Ob' and Yenisey rivers.

Within the scope of present study, the water quality of stream Karaçomak in Kastamonu-Turkey was investigated. Water samples were collected from 9 stations selected on Karaçomak stream, considering the pollution points and the points, where the entrance of water into stream is high. The samples taken were analyzed in terms of water temperature, pH, dissolved oxygen, saltiness, electrical conductivity, chemical composition and heavy metal content, and for their genotoxic and cytotoxic potential. Physicochemical evaluation indicated that all samples had heterogeneous intensity of environmental influence, but the considerable impact was noticed for the third and seventh stations. The present study highlights the need for continuous evaluation of water pollution level, and is intended to help in mitigating the environmental impacts and improve environmental performance.

1997-01-01

Between 1965 and 1988, 16 naval reactor vessels were dumped in the Arctic Kara Sea. Six of the vessels contained spent nuclear fuel that had been damaged during accidents. In addition, a container holding ∼ 60% of the damaged fuel from the No. 2 reactor of the atomic icebreaker 'Lenin' was dumped in 1967. Before dumping, the vessels were filled with a solidification agent, Conservant F, in order to prevent direct contact between the seawater and the fuel and other activated components, thereby reducing the potential for release of radionuclides into the environment. The key ingredient in Conservant F is furfurol (furfuraldehyde). Other constituents vary, depending on specific property requirements, but include epoxy resin, mineral fillers, and hardening agents. The properties of Conservant F in both its cured and uncured states are discussed, and the potential performance of the waste packages containing spent nuclear fuel in the Arctic Kara Sea is evaluated.

In 1992, it became known to the public that the former Soviet Union had dumped large amounts of radioactive waste in the Arctic Ocean since about 1959. The waste was dumped into the Kara and Barents Seas in liquid and solid form, sealed in barrels or containers, as reactor parts but also as complete ship reactors including spent fuel. Wrecks of nuclear submarines were dumped near the coast of Novaya Semlya, in depths less than 50 m. The dumping took place in strong contradiction to international rules and conventions. After some confusion and overestimation of the total radioactive inventory, the amount of the waste and the dump site locations are well known, meanwhile. International pressure and the more open information policy of Russia helped to improve the situation. Various international fora primarily within the IAEA and the Arctic Monitoring and Assessment Programme (AMAP) investigated the potential consequences from these dumping practices. This report is the German contribution to these international assessments. The dumped objects in the Kara Sea encompass 17 nuclear ship reactors, seven of them still carrying spent fuel. Four dump sites are located in small and shallow fjords at the east coast of Novaya Semlya, and in the Novaya Semlya Trough, in max. depth of 420 m. The total radioactive inventory was, at the time of dumping, 37 PBq. During the project numerous samples from seawater and sediment were analysed on artificial radionuclides in Arctic waters. This included samples from the Kara Sea but also samples around the Russian nuclear submarine Komsomolets sunk in the Norwegian Sea at a depth of about 1700 m in 1989. Numerical hydrodynamic models in local, regional and global scale were used to predict the potential dispersion of released radionuclides from the dumped wastes and reactors in the Kara Sea. (orig.)

Full Text Available This paper analyses the anomalous hydrometeorological situation that occurred at the beginning of 2012 in the seas of the Russian Arctic and Russian South. Atmospheric blocking in the temperate zone and the extension of the Siberian High to the Iberian Peninsula (known as the Voeikov et al. axis led to a positive anomaly of air and water temperatures and a decrease in the ice extent in the Barents and Kara Seas. At the same time a prolonged negative air temperature anomaly was recorded in central and southern Europe and led to anomalously severe ice conditions in the Sea of Azov. Winter hydrographic conditions in the Barents and Kara Seas are illustrated by a unique set of observations made using expendable bathythermosalinographs (XCTD.

The MIS 6-5e event, associated with the high marine limit, implies ice-sheet thickness of >2000 m only 200 km from the deep Arctic Ocean, consistent with published evidence of ice grounding at ~1000 m water depth in the central Arctic Ocean. Till fabrics and glacial tectonics record...... repeated expansions of local ice caps exclusively, suggesting wet-based ice cap advance followed by cold-based regional ice-sheet expansion. Local ice caps over highland sites along the perimeter of the shallow Kara Sea, including the Byrranga Mountains, appear to have repeatedly fostered initiation...

The key ingredient in Conservant F is furfural (furfuraldehyde). Other constituents vary, depending on specific property requirements, but include epoxy resin, mineral fillers, and hardening agents. In the liquid state (prior to polymerization) Conservant F is a low viscosity, homogeneous resin blend that provides long work times (6--9 hours). In the cured state, Conservant F provides resistance to water and radiation, has high adhesion properties, and results in minimal gas evolution. This paper discusses the properties of Conservant F in both its cured and uncured states and the potential performance of the waste packages containing spent nuclear fuel in the Arctic Kara Sea

Hydrographic structure and variability of the Kara Sea: Implications for pollutant distribution

Science.gov (United States)

Pavlov, V. K.; Pfirman, S. L.

Nuclear activity on land and dumping of waste in the Siberian shelf seas mean that the Kara Sea is most likely to experience inputs of radioactivity. Industrial and other anthropogenic activities in the expansive Ob' and Yenisey watersheds also contribute organochlorines, heavy metals and oil to this region. Contaminant fate is influenced by the distribution of the river discharge and processes associated with ice formation and ocean currents. Although average conditions are important in the transport of pollutants, events such as storms and iceberg gouging may be critical in deciding the ultimate fate of dumped and released contaminants.

1997-01-01

Between 1965 and 1988, 16 marine reactors from seven Russian submarines and the icebreaker Lenin, each of which suffered some form of reactor accident, were dumped in a variety of containments, using a number of sealing methods, at five sites in the Kara Sea. All reactors were dumped at sites that varied in depth from 12 to 300 m and six contained their spent nuclear fuel (SNF). This paper examines the breakdown of the reactor pressure vessel (RPV) barriers due to corrosion, with specific emphasis on those RPVs containing SNF. Included are discussions of the structural aspects of the steam generating installations and their associated RPVs, a summary of the disposal operations, assumptions on corrosion rates of structural and filler materials, and an estimate of the structural integrity of the RPVs at the present time (1996) and in the year 2015

On 99Tc, 137Cs and 90Sr in the Kara Sea

Dahlgaard, H.

1995-01-01

Technetium-99 in the Arctic seas originate mainly from European reprocessing plants whereas 137 Cs and 90 Sr have many sources. It appears that for 137 Cs, re-mobilisation from the Irish Sea of sedimented activity from earlier discharges and the outflow of Baltic water contaminated with Chernobyl activity, are more important sources to the present contamination of the Kara Sea than new European discharges. As opposed to 137 Cs and 99 Tc, 90 Sr is correlated with low salinity waters. It is argued, that this is due to runoff of global atmospheric fallout 90 Sr from land. 7 refs., 4 figs., 1 tab

As a prerequisite for most evaluations of radionuclide transport pathways in marine systems, it is necessary to obtain basic information on the sorption potential of contaminants onto particulate matter. Kd values for use in modeling radionuclide dispersion in the Kara Sea have been determined as part of several international programs addressing the problem of radioactive debris residing in Arctic Seas. Field and laboratory Kd experiments were conducted for the following radionuclides associated with nuclear waste: americium, europium, plutonium, cobalt, cesium and strontium. Emphasis has been placed on two regions in the Kara Sea: (i) the Novaya Zemlya Trough (NZT) and (ii) the mixing zones of the Ob and Yenisey Rivers (RMZ). Short-term batch Kd experiments were performed at-sea on ambient water column samples and on samples prepared both at-sea and in the laboratory by mixing filtered bottom water with small amounts of surficial bottom sediments (particle concentrations in samples = 1-30 mg/l). Within both regions, Kd values for individual radionuclides vary over two to three orders of magnitude. The relative particle affinities for radionuclides in the two regions are americium approximately equal to europium > plutonium > cobalt > cesium > strontium. The values determined in this study agree with minimum values given in the IAEA Technical Report [IAEA, 1985. Sediment Kd's and Concentration Factors for Radionuclides in the Marine Environment. Technical Report No. 247. International Atomic Energy Agency, Vienna.]. Given the importance of Kd's in assessments of critical transport pathways for radionuclide contaminants, we recommend that Kd ranges of values for specific elements rather than single mean values be incorporated into model simulations of radionuclide dispersion.

The paper represents results of remote sensing by means of Laser Induced Fluorescence LiDAR during the expedition in Kara Sea in summer 2016. The expedition took place in Western and Southern parts of Kara Sea including Ob and Yenisei areas from June, 14 to August, 20 2016. The LiDAR observations were obtained from the research vessel Mstislav Keldysh and included 4600 km of almost continuous measurements and 94 complex stations. As a result now there is a vast LiDAR database available for scientific purposes. The data were processed and recalculated providing a set of high resolution maps of distribution of main oceanographic water quality parameters including chlorophyll "a", total organic carbon and total suspended matter in surface layer. The proceeded maps give a precise information about the location of frontal zones between Ob and Yenisei waters and Kara Sea waters, provide a detailed picture of complex surface water structure in central Kara Sea and other locations and present data about spatial distinction of concentrations of measured water parameters. The LiDAR measurements were afterwards compared to data, obtained by underway flow-through CTD measuring system and satellite images providing adjunct information on water parameters' distribution features. The instruments of UFL (Ultraviolet fluorescent LiDAR) series were developed by the Shirshov Institute of Oceanology, Moscow, Russia, and have been successfully used in lots of scientific expeditions in different water areas. UFL LiDARs take measurements with sampling rate up to 2 Hz from the vessel under way in any weather or sunlight conditions. The measurements are linked to a GPS, and so all data are geo-tagged and can be used to create interpolated maps of the measured parameters. The instrument analyses backward signal from dual excitation (355, 532 nm) laser pulses emitted at 2 Hz. The signal is detected across 11 bands in series (355, 385, 404, 424, 440, 460, 499, 532, 620, 651, 685 nm) on

In the 1950s, the total area of glaciers occupying separate islands and archipelagos of the Barents and Kara seas exceeded 92,300 km² (Atlas of the Arctic 1985). The overall glacier volume reached 20,140 km³ and the average ice thickness was given as 218 m. Our recent remote sensing studies and mass-balance estimates using spaceborne ASTER and LANDSAT imagery, ERS and JERS radar interferometric mosaics, and ICESat altimetry data revealed that, in the 2000s, the areal extent and volume of Barents-Kara glaciation amounted to 86,200±200 km² and 19,330±20 km³, respectively. The annual loss of land ice influenced by severe climate change in longitudinal direction was determined at approx. 8 km³/a in Svalbard, 4 km³/a both in the Franz Josef Land and Novaya Zemlya archipelagos, and less than 0.3 km³/a in Severnaya Zemlya over the past 50 years. The average ice thickness of remaining glaciation increased to 224 m. This fact was explained by rapid disintegration of thinner glacier margins and essential accumulation of snow at higher glacier elevations. Both effects were clearly visible in the series of satellite image maps of glacier elevation changes generated within the framework of the INTEGRAL, SMARAGD and ICEAGE research projects. These maps can be accessed at http://joanneum.dib.at/integral or smaragd (cd results). The largest negative elevation changes were typically detected in the seaward basins of fast-flowing outlet glaciers, both at their fronts and tops. Ablation processes were stronger manifested on southern slopes of ice caps, while the accumulation of snow was generally higher on northern slopes so that main ice divides "shifted" to the north. The largest positive elevation changes (about 100 m) were found in the central part of the study region in the accumulation areas of the biggest ice caps, such as Northern Ice Cap in Novaya Zemlya, Tyndall and Windy ice domes in Franz Josef Land, and Kvitoyjokulen at Kvitøya.

A study of radionuclide distributions in the Barents Sea sediments was carried out in 1992. The conclusions of the study are as follows: 1) Elevated levels of artificial radionuclides as great as 15,000 Bq/kg for 239,240 Pu, 250 Bq/kg for 137 Cs and 100 Bq/kg for 60 Co were measured in sediments in Chermaya Bay which have been contaminated by several nuclear tests conducted in the 1950s. 2) Sediment-depth distributions of 239,240 Pu and other artificial radionuclides are consistent with results from biodiffusion models that are constrained by 210 Pb sediment-depth distributions. These results indicate that sedimentation rates in Chernaya Bay are low ( 249 Pu/ 239 Pu and 241 Pu/ 239 Pu atom ratios of 0.030 and 0.0012, respectively and a 241 Am/ 239,240 Pu activity ratio of 0.05 (compared to 0.3 in fallout) which provides a method for tracking its dispersion over distances of 100 km into the Barents Sea. 4) Artificial radionuclide levels in sediments and seawater near a sunken barge loaded with radioactive wastes in the Novaya Zemlya trough are similar to background fallout levels in the Kara Sea and provide little evidence for the release of radioactive contaminants from the dumpsite. 7 refs., 4 figs

There are several high level {sup 137}Cs anomaly zones detected in the deposits of the SW part of the Kara Sea. These anomaly zones were formed in the Ob' and the Enisey river estuaries due to the geochemical 'river-sea' boarder barrier. Level of radiocaesium specific activity reaches 120 Bq*kg{sup -1} in the deposits from these zones. Radiochemical enterprises occur in the both river basins. Their activity results in caesium-137 transfer into the river net. Vast area is contaminated by {sup 137}Cs after nuclear weapons in Semipalatinsk test-site and Kyshtym disaster in the Ob' river basin. Moreover, caesium comes to the Ob' and the Enisey river basins with global atmospheric fallout. The inflow of global fallout caesium-137 to the catchments is 660 kCi (320 kCi including radioactive decay) that is 4 times higher than {sup 137}Cs emission due to Fukushima disaster. Therefore, these river basins as any other huge catchment are an important sources of radioactive contamination of the Arctic Ocean. The aim of our research is to study behavior of global fallout caesium-137 in the landscapes of the Ob and the Enisey river basins. We studied caesium-137 behavior on the example of first order catchments in taiga, wetland, forest-steppe, steppe, and semi-arid landscapes. Geographic information system (GIS) was made. The tenth-order catchments (n=154, Horton coding system) shape 20-groups due to topsoil properties controlling cesium mobility. Eleven first-order basins, characterized 7 groups of tenth order catchments, were studied. And 700 bulk-core soil samples were collected in 2011-2013. Cesium runoff is calculated for 3 first-order river basins in taiga and forest-steppe landscapes. Storage of global fallout caesium-137 declines from undisturbing taiga first-order river basin (90% of cumulative fallout including radioactive decay)> arable steppe and fores-steppe (70 - 75%)> undisturbing wetland (60%). Caesium-137 transfer is high in arable lands

Within the course of operating its nuclear navy, the former Soviet Union (FSU) disposed of reactor vessels and spent nuclear fuel (SNF) in three fjords on the east coast of Novaya Zemlya and in the open Kara Sea within the Novaya Zemlya Trough during the period 1965 to 1988. The dumping consisted of 16 reactors, six of which contained SNF and one special container that held ca. 60% of the damaged SNF and the screening assembly from the No. 2 reactor of the atomic icebreaker Lenin. At the time, the FSU considered dumping of decommissioned nuclear submarines with damaged cores in the bays of and near by the Novaya Zemlya archipelago in the Arctic Kara Sea to be acceptable. To provide an additional level of safety, a group of Russian scientists embarked upon a course of research to develop a solidification agent that would provide an ecologically safe barrier. The barrier material would prevent direct contact of seawater with the SNF and the resultant leaching and release of radionuclides. The solidification agent was to be introduced by flooding the reactors vessels and inner cavities. Once introduced the agent would harden and form an impermeable barrier. This report describes the sample preparation of several ''Furfurol'' compositions and their leach testing using cesium 137 as tracer

The urinary excretion of purine derivatives (PD) was measured in four Yerli Kara (Bos indicus) bulls in two experiments, a fasting experiment lasting for 7 days and the other, where animals were given a diet containing 30% wheat straw and 70% compounded feed at four levels of intake (40, 60, 80 and 95% of voluntary feed intake). In the second experiment, which was carried out according to a 4 x 4 Latin Square design, four animals receiving 60 and 95% levels of intake were also given a single injection of 8- 14 C-uric acid via a jugular catheter. In addition to the above two experiments, the activity of xanthine oxidase and uricase in plasma, liver and intestinal mucosa obtained from Yerli Kara cattle was also determined. In the first experiment, fasting PD excretion averaged 0.691 (± 0.053) mmol/kg W 0.75 /d. Glomerular filtration rate (GFR), tubular load and net re-absorption of allantoin between pre-fasting and fasting were statistically significant (P 14 C-uric acid as total PD was 72.5 and 89.9% for 60 and 95% feeding levels, respectively. The average recovery was 81%. Plasma kinetics measured by 8- 14 C-uric acid indicated that the total compartment pool size was 214.0 (± 43.8) and 250.3 L (± 29.5) for 60 and 95% feeding levels, respectively. GFR, tubular load and net re-absorption of uric acid and allantoin were not affected by feed intake. The allantoin:PD molar ratios changed between 0.78 to 0.93 for the four levels feed intake. There were significant correlations between PD excretion (mmol/d), and DDMI (kg/d) and DOMI (kg/d) (r = 0.99, P 0.75 DDMI, 19.8 mmol/kg DDMI and 22.7 mmol/kg DOMI. Xanthine oxidase and uricase activities were: 1.34 (± 0.72) and 0.44 (± 0.05), and 0.13 (± 0.03) and 0.08 (± 0.03) unit/g fresh tissue in liver and intestinal mucosa, respectively. In plasma xanthine oxidase activity was 5.0 (± 1.2) unit/L while uricase activity was absent. (author)

Three experiments were conducted to evaluate of the developed techniques for uric acid, allantoin and creatinine in Yerli Kara cross-breed cattle on farm at different feeding level locally available feed resources and linking the observed information to feed intake and to assess of protein nutrition status of Yerli Kara cross-breed dairy cattle using urinary PD and creatinine excretion. In Experiment I. Response of daily PD excretion to feed intake in Yerli Kara cross-breed on state farm was measured. Animals were fed a mixed diet containing 30 % wheat straw and 70 % compounded feed. The diet contained 90 % DM, its N and OM contents were 124 and 950 g/kg DM, respectively. In Experiment II. Spot urine sampling techniques was applied at state farm. Four Yerli Kara cross-breed bulls live weight with a mean of 211±41.3 kg were used. Experimental design, feeding and diet were the same as in Experiment I. The treatments were [located according to a 4x4 Latin Square design. In Experiment III. Spot urine sampling techniques was applied at smallholder farms. Compound feed containing 65 % barley, 25 % bran, 6 % sunflower seed meal, 3 % manner dust and 1 % mineral and vitamin mixture (120 g/kg DM-Crude Protein and 950 g/kg DM-Organic Matter)- was offered total in between 2 to 3 kg in two parts one in the morning (07:30 h) and one in the afternoon (17:00 h). Compound feed ingredients were similar given to all animals but Groups I, II and III animals were receiving 1 to 2 kg/d of straw (30 g CP/kg DM, 93Og OM/kg DM), grass hay (70g CP/kg DM, 915 g OM/kg DM), straw and grass hay respectively. There were significant correlations (R 2 =0.99) between PD excretion (mmol/d) and DOMI (kg/d) for YK-C cattle. PD execration (mmol/L) was plotted against PD: Creatinine W 0.75 to obtain slope and use as constant for the estimation of daily PD excretion from spot sampling from animals held by small holders. The equation could be expressed as: PD (mmol/d)=8.27+0.960 (PD:CxW 0.75 ). The

Ar-40 to Ar-39 ages of the large impact structures Kara and Manicouagan and their relevance to the Cretaceous-Tertiary and the Triassic-Jurassic boundary

Trieloff, M.; Jessberger, E. K.

Since the discovery of the Ir enrichment in Cretaceous-Tertiary boundary clays in 1980, the effects of a 10-km asteroid impacting on the Earth 65 Ma ago have been discussed as the possible reason for the mass extinction--including the extinction of the dinosaurs--at the end of the Cretaceous. But up to now no crater of this age that is large enough (ca. 200 km in diameter) has been found. One candidate is the Kara Crater in northern Siberia. Kolesnikov et al. determined a K-Ar isochron of 65.6 +/- 0.5 Ma, indistinguishable from the age of the K-T boundary and interpreted this as confirmation of earlier proposals that the Kara bolide would have been at least one of the K-T impactors. Koeberl et al. determined Ar-40 to Ar-39 ages ranging from 70 to 82 Ma and suggested an association to the Campanian-Maastrichtian boundary, another important extinction horizon 73 Ma ago. We dated four impact melts, KA2-306, KA2-305, SA1-302, and AN9-182. Results from the investigation are discussed.

Full Text Available The Kara Sea coasts were studied using comprehensive stratigraphic and geocryological methods. The paper presents the new analytical studies of ground ice and Quaternary deposits of Western Taymyr and presents the results of spore and pollen, foraminifera, grain-size, mineralogical, geochemical, oxygen isotopic, and other analyses. Several stratigraphic-geocryological transects from Yenisey and Gydan Bays enable us to refine the stratigraphy and palaeogeographical reconstruction of the environments and freezing of Late Pleistocene-Holocene sediments. Marine sedimentation conditions during the late Kargino time (MIS3 changed to continental conditions in MIS2 and MIS1. Marine sediments were frozen syn- and epigenetically with cryotexture and ground ice formation. Ice wedges formation corresponds to the end of the Pleistocene (MIS2 and during cooler periods of the Holocene.

Potential ocean–atmosphere preconditioning of late autumn Barents-Kara sea ice concentration anomaly

Full Text Available Many recent studies have revealed the importance of the climatic state in November on the seasonal climate of the subsequent winter. In particular, it has been shown that interannual variability of sea ice concentration (SIC over the Barents-Kara (BK seas in November is linked to winter atmospheric circulation anomaly that projects on the North Atlantic Oscillation. Understanding the lead–lag processes involving the different components of the climate system from autumn to winter is therefore important. This note presents dynamical interpretation for the ice-ocean–atmosphere relationships that can affect the BK SIC anomaly in late autumn. It is found that cyclonic (anticyclonic wind anomaly over the Arctic in October, by Ekman drift, can be responsible for positive (negative SIC in the BK seas in November. The results also suggest that ocean heat transport via the Barents Sea Opening in September and October can contribute to BK SIC anomaly in November.

A 5-m long core of bottom sediments from the Kara Bogaz Gol Bay of the Caspian Sea, 4- m and 2-m cores from the Issyk Kul Lake of the Thian Shan Mountains, and a 4-m core from the Aral Sea were examined for evidence of climatic and environmental changes in the catchment basin of the Central Asia Region. The distribution of 18 O and 13 C in the bulk carbonates, 2 H in the pore water, radiocarbon age, oxygen and hydrogen isotopes in the lake water, abundance of CaCO 3 , MgCO 3 , and the basic salt ions of Na + , K + , Cl - , SO 4 2- in the cores were measured. The isotope and hydrogeochemical data of the Kara Bogaz Gol Bay sediments prove a historical scenario for the basin which suggests that fresh water has been discharged to the Caspian Sea during the Bay's humid episode across the Central Asia Region (∼ 9 Ka BP). Isotope and geochemical evidence indicate that the sedimentation of the upper core segment has taken place during the last ∼2.2 Ka BP in the environment of sea water recharged from the Central Caspian Basin. The period of between 4.3 and 6 Ka BP, which relates to the core depth interval of between 170 cm and 260 cm, demonstrates the most dramatic change in the sedimentation rate in the Issyk Kul Lake. It means that active melting of the mountain glaciers and warming of climate has happened just in this period. The swamp plant peat layers at depths of 230 cm and 130 cm indicate that during 3.5-3.7 Ka BP and 1.6-1.8 Ka BP the Aral Sea dried and broke up into a number of lakes and swamps. Sediment cores taken from the bottom of the Kara Bogaz Gol Bay, Lake Issyk Kul and Aral Sea show periodic rise and fall in water levels during the last ∼10 000 years. Two peat layers within the sediment core of the Aral Sea and dated at 1.6-1.8 Ka BP and 3.5-3.7 Ka BP demonstrate that this reservoir also periodically dried. (author)

The polar bear movement trajectory in relation to onset date of the sea-ice break-up was studied in the coastal zone of the Taimyr Peninsula, eastern part of the Kara Sea, using as an example a female polar bear tagged by a radio collar with an Argos satellite transmitter. Analysis of the long-term pattern of ice melting and tracking, by means of satellite telemetry, of the female polar bear who followed the ice-edge outgoing in the north-eastern direction (in summer 2012) suggests that direction of the polar bear movement depends precisely on the direction of the sea-ice cover break-up.

Russian-Norwegian expeditions to the Kara Sea and to dumping sites in the fjords of Novaya Zemlya have taken place annually since 1992. In the fjords, dumped objects were localised with sonar and ROV equipped with underwater camera. Enhanced levels of 137Cs, 60Co, 90Sr and 239,240Pu in sediments close to dumped containers in the Abrosimov and Stepovogo fjords demonstrated that leaching from dumped material has taken place. The contamination was inhomogeneously distributed and radioactive particles were identified in the upper 10 cm of the sediments. 137Cs was strongly associated with sediments, while 90Sr was more mobile. The contamination was less pronounced in the areas where objects presumed to be reactor compartments were located. The enhanced level of radionuclides observed in sediments close to the submarine in Stepovogo fjord in 1993 could, however, not be confirmed in 1994. Otherwise, traces of 60Co in sediments were observed in the close vicinity of all localised objects. Thus, the general level of radionuclides in waters, sediments and biota in the fjords is, somewhat higher or similar to that of the open Kara Sea, i.e. significantly lower than in other adjacent marine systems (e.g. Irish Sea, Baltic Sea, North Sea). The main sources contributing to radioactive contamination were global fallout from atmospheric nuclear weapon tests, river transport from Ob and Yenisey, marine transport of discharges from Sellafield, UK and fallout from Chernobyl. Thus, the radiological impact to man and the arctic environment of the observed leakages from dumped radioactive waste today, is considered to be low. Assuming all radionuclides are released from the waste, preliminary assessments indicate a collective dose to the world population of less than 50 man Sv.

Methane Release and Pingo-Like Feature Across the South kara Sea Shels, an Area of Thawing Offshore Permafrost

Serov, P.; Portnov, A.; Mienert, J.

2015-12-01

Thawing subsea permafrost controls methane release from the Russian Arctic shelf having a considerable impact on the climate-sensitive Arctic environment. Our recent studies revealed extensive gas release over an area of at least 7500 km2and presence of pingo-like features (PLFs), showing severe methane leakage, in the South Kara Sea in water depths >20m (Serov et al., 2015). Specifically, we detected shallow methane ebullition sites expressed in water column acoustic anomalies (gas flares and gas fronts) and areas of increased dissolved methane concentrations in bottom water, which might be sufficient sources of carbon for seawater-atmosphere exchange. A study of nature and source of leaking gas was focused on two PLFs, which are acoustically transparent circular mounds towering 5-9 m above the surrounding seafloor. One PLF (PLF 2) connects to biogenic gas from deeper sources, which is reflected in δ13CCH4 values ranging from -55,1‰ to -88,0‰ and δDCH4values varied from -175‰ to -246‰. Low organic matter content (0.52-1.69%) of seafloor sediments restricts extensive in situ methane production. The formation of PLF 2 is directly linked to the thawing of subsea permafrost and, possibly, decomposition of permafrost related gas hydrates. High accumulations of biogenic methane create the necessary forces to push the remaining frozen layers upwards and, therefore, form a topographic feature. We speculate that PLF 1, which shows ubiquitously low methane concentrations, is either a relict submerged terrestrial pingo, or a PLF lacking the necessary underlying methane accumulations. Our model of glacial-interglacial permafrost evolution supports a scenario in which subsea permafrost tapers seaward and pinches out at 20m isobaths, controlling observed methane emissions and development of PLFs.

Full Text Available L’artiste afro-américaine Kara Walker (1969- travaille principalement sur les silhouettes découpées, forme d’art des XVIIIe et XIXe siècles qui était alors utilisée pour les portraits, les caricatures et la décoration. Un grand nombre de critiques d’art, tout particulièrement Howardena Pindell, accuse Walker de renforcer les stéréotypes raciaux et de ne pas réussir à mettre le présent en relation avec le passé dans son travail. Cet article considère l’aspect humoristique du travail de Walker et défend l’idée que le rire est une pratique spatiale, en tant qu’expérience vécue, qui occupe une partie seulement de l’espace se trouvant entre les stéréotypes raciaux et la vie. Offrir une perspective ludique est une stratégie clé dans un contexte de recherche d’un espace à partir duquel il est possible de critiquer et d’analyser des imaginaires sociaux irréconciliables. La distorsion gênante de Walker se situe dans son insistance à aplanir les corps et donc à leur retirer tout espace, tout en les étalant littéralement en tant que projections sur une surface plane, accentuant de ce fait le coté dramatique du blanc et du noir. A première vue, les silhouettes de Walker semblent perpétuer un code dichotomique de la différence culturelle. Cependant, cet article montre que le troisième espace, celui du rire, exerce une force perturbatrice qui commente la politique de la représentation à partir des stéréotypes eux-mêmes. Cet argument est illustré par son panneau Safety Curtain I qui servit de rideau à l’Opéra de Vienne pendant l’hiver 1998-1999.

Waste biodegradation has been largely investigated in the literature by using conventional tests like the BMP test and the respirometric test, whereas only few studies deal with the use of leaching tests in combination with biological activity measurements. Consequently, this study used an improved leaching test to evaluate the biodegradability of two deposits of fresh household waste from the city of Kara in Togo. The first deposit came from households in neighborhoods located in the outskirts of the city and the second consisted of fresh waste, mainly composed of business waste and household waste, collected in the urban center and aimed at being deposited in the landfill. A physicochemical characterization of the two deposits completed the leaching test. The biological activity was monitored by measuring O(2) consumption and CO(2) production. pH, DOC/OM, VFA/DOC ratios and the SUVA index was measured in the leaching juice to assess both the state of degradation of the waste in the deposits and the ability of the organic matter to be mobilized quickly and to be easily assimilated by microorganisms. The biodegradability of waste from the city of Kara correlated with their origin even though the physical characteristics of the two deposits studied differed greatly. Copyright © 2012 Elsevier Ltd.

As to intelligent transport systems (ITS), the paper views the outline of the R and D and diffusion in Europe, the U.S. and Japan and trially estimated the effect of reduction in greenhouse gas, and worked out visions/scenario for diffusion of ITS. As developmental fields contributing to reduction in greenhouse gas, the following were taken up: 1) AVCS (advanced vehicle control system), 2) automatic rates receiving system, 3) traffic management, 4) plans of operation management/allocation of commercial cars, 5) modal shift of the material flow, and 6) public traffic in passenger transportation. As effects by developmental field, 1) and 5) are especially effective. 4) is promising because of its easiness in introduction, and 2) is also a promising technology as a tool to introduce an electronic road pricing system on general roads in future in addition to the effect of reducing heavy traffic by its introduction to expressways. However, the higher the service level on the facility side becomes, the more the traffic demand amount becomes. By how to introduce ITS, it possibly occurs that improvement of the situation will not be made at all on the future vehicle traffic system. 38 refs., 42 figs., 52 tabs.

Equations describing radioisotope transfers in the suspension river water-bottom sediments based on radionuclide migration from industrial wastes and washing off reservoir are formulated. Coefficients of the equations were determined by means of measured data processing. On this base floodplaine sediments were estimated, dependence of radionuclide waste from time for all period of functioning of the plant was determined and their concentrations in water and bottom sediments were calculated. Balances between wastes, washing off the reservoir and radionuclide migration in bottom sediments, bottom land and the Kara Sea were formulated for the past. Procedure for the estimation of the migration of radionuclide exchange forms from bottom sediments following sharp decrease of waste in 1992 was developed. On the base of this effect and redistribution of radionuclides between bottom sediments and floodplaine sediments the rate of self-purification of the river in the future was evaluated [ru

Artificial radionuclides play a specific role in the hydrochemical, geochemical, and hydrobiological processes that are currently occurring in the western Arctic. The existing data on radioactive contamination of different plant and animal species inhabiting the sea shelf are fragmentary. Hence, it was difficult to follow the transformation of radionuclides during their transmission along food chains, from phyto- and zoo-plankton to benthos, fish, birds, and marine mammals. In 1990-1994, the Murmansk Institute of Marine Biology organized expeditions to collect samples of residues on the sea floor and also of benthos, benthic fish, macrophytes, and other organisms inhabiting the shelf of the Barents and Kara Seas. These samples were tested for cesium-137, cesium-134, strontium-90, plutonium-239, plutonium-240, americium-241, and cobalt-60 in Rovaniemi (Finland) by the regional radiation administration of the Finnish Centre for Radiation and Nuclear Safety. Over 1000 tests were made. Their results provided new data on the content and distribution of these radionuclides among different components of marine ecosystems. 7 refs

In the presentation the laboratory studies results of the Kara-Balta Complex area soils by the γ-spectrometry method for quantitative analysis of γi-radiating isotopes content ( 226 Ra and products of its decay, as well as another isotopes, for instant, of the thorium series) are presented. For analysis of soils γ-spectra the scintillation γ-spectrometer with NaI(Tl) crystal in the capacity of detector was used. It was determined, that the main reasons for 226 Ra anomalous concentration appealing are the Hydrometallurgical Plant' wastes losses during hydro-transporting at the pipeline accidents periods, also the ore losses at their reloading, a cars decontamination and radionuclides washing from wasted technological constructions outside the working rooms

Geology of the Severnaya Zemlya Archipelago and the North Kara Terrane in the Russian high Arctic

2008-05-01

The Severnaya Zemlya Archipelago is located at 80°N near the continental shelf break, between the Kara and Laptev seas. Sedimentary successions of Neoproterozoic and Palaeozoic age dominate the bedrock geology. Together with Northern Tajmyr, Severnaya Zemlya constitutes the main land areas of the North Kara Terrane (NKT), which is inferred here to have been a part of the Timanide margin of Baltica, i.e. an integral part of Baltica at least since the Vendian. Vendian turbidites derived from the Timanide Orogen are inferred to have been deposited on Neoproterozoic greenschist facies, granite-intruded basement. Shallow-water siliclastic deposition in the Early to Mid-Cambrian was followed by highly organic-rich shales in the Late Cambrian and influx of more turbidites. An episode of folding, the Kan’on River deformation, separates these formations from the overlying Tremadocian conglomerates and sandstones. In the Early Ordovician, rift-related magmatic rocks accompanied the deposition of variegated marls, sandstones, carbonates and evaporites. Dark shales and gypsiferous limestones characterise the Mid-Ordovician. Late Ordovician quartz-sandstones mark a hiatus, followed by carbonate rocks that extend up into and through most of the Silurian. The latter give way upwards into Old Red Sandstones, which are inferred to have been deposited in a Caledonian foreland basin. Deformation, reaching the area in the latest Devonian or earliest Carboniferous and referred to as the Severnaya Zemlya episode, is thought to be Caledonian-related. The dominating E-vergent structure was controlled by décollement zones in Ordovician evaporite-bearing strata; detachment folds and thrusts developed in the west and were apparently impeded by a barrier of Ordovician igneous rocks in the east. Below the décollement zones, the Neoproterozoic to Early Ordovician succession was deformed into open to close folds. The exposed strata in the lower structural level have been juxtaposed with

The samples collected and analysed during joint work between the Finnish Centre for Radiation and Nuclear Safety and the Murmansk Marine Biological Institute cover a rather large area of the arctic in north west Russia. All the analysed sediments, algae, benthic and fish samples, have shown surprisingly low radionuclide concentrations and indicate that the open sea areas are almost uncontaminated. But the most interesting locations with potential risk sources are closed areas. 134 Cs isotope originating from the fallout of the Chernobyl accident was measured only in terrestrial samples collected on the Kola peninsula and around the White Sea. Small amounts of this isotope with only 2 years half-life was also noticed in some sediment samples from White Sea. 134 Cs isotopes was not noticed in any terrestrial sample collected from the coastal area between the Kanin peninsula and the Jenisey river. The very low concentrations of 134 Cs isotope measured in Kara Sea sediment samples were usually in association with an outlet of a river and were obviously transported by river water from the central parts of Russia. The measured low concentrations of the antropogenic radionuclides in the Barents and Petshora Sea originate obviously from the global fallout. The higher White Sea concentrations contain also additional fallout from the Chernobyl accident and probably also some terrestrial runoff. Low concentration of 60 Co isotopes in some sediment, algae and benthic fauna samples, reveals, however, slight fresh contamination, as were concentrations also at the outlet of Jenisey river. The results on well documented sampling locations represent also background data for possible leakage or other accidents. 5 refs., 3 figs, 3 tabs

Recent data indicate that there are potentially large sources of radionuclide contamination on the Ob River system. To quantify the existing radionuclide contamination from a possible catastrophic event data and models have been used to quantify scenarios. Using a compilation of Russian data on the radionuclide contamination, hydrologic data and studies on the sediment transport process a conceptual model has been developed of the Ob system, and a numerical model has been applied to estimate the radionuclide flux to the Kara Sea. The initial results of the river modeling in the Mayak region show how important watershed flow from the marshes are to the hydrologic budget of the area. The preliminary analysis of the sediment flux indicates the need to consider the depositional (storage) regions such as the Asanow Marsh. 31 refs., 5 figs

When ships with nuclear reactors or nuclear materials aboard suffer shipwreck or in the case of burial or dumping of radioactive wastes, atmospheric fallout, etc., radionuclides may be released and spread in the sea, contaminating the sea water and the sea bottom. When a nuclear submarine (NS) is dumped this spread of activity may occur due to gradual core destruction by corrosion over many years. The objective of this paper is to develop a mathematical model of radionuclide dispersion and to assess the population dose and radiation risk for radionuclide release from the NS No. 601, with Pb-Bi coolant that was dumped in the Kara Sea

Accelerator mass spectrometry (AMS) has been used to determine Pu activity concentrations and 240 Pu/ 239 Pu isotope ratios in sediments from the Kara Sea and radioactive waste dumping sites at Novaya Zemlya. Measured 239,240 Pu activities ranged from 0.06 - 9.8 Bq/kg dry weight, 240 Pu/ 239 Pu atom ratios ranged from 0.13 to 0.28, and 238 Pu/ 239,240 Pu activity ratios from 0.02 to 0.6. Perturbations from global fallout isotope ratios were evident at three sites: the Yenisey Estuary and Abrosimov Fjords where 240 Pu/ 239 Pu ratios were lower (0.13-0.14); and Stepovogo Fjord sediments where ratios were higher (up to 0.28) than fallout ratios. Based on procedural blanks, detection limits for AMS were below 1 fg Pu and the method showed good precision for isotope ratio measurements, minimal matrix, interference and memory effects. For high level samples, comparison between alpha spectrometry and AMS gave good agreement for measurement of 239,240 Pu activity concentrations. (author)

The development of Arctic coastal regions is now in progress due to significant amount of hydrocarbon deposits discovered. In high latitudes, natural hazards such as coastal erosion and thermoerosion, deflation, linear erosion and thermal denudation, ice gouging can make petroleum production and transport unprofitable. A prominent feature of Kara Sea, as well as other Arctic seas, is the development of coast in permafrost conditions. Despite the long ice period (up to 9 months), during the ice free period coastal dynamics are very intensive. If pipeline landfall site occurs at a shore section with high retreat rate (1 - 3m/year and higher), danger of pipeline damage due to exposure, line sagging and mechanical deformations becomes high. Protective measures may appear inefficient, since shore sections with active coastal erosion are subject not only to bluff retreat, but also to nearshore zone and coastal slope erosion. Exposed pipeline sections also get in danger of sea ice effect. For correct definition of coastal dynamics setting we use dual approach. The first part is perennial instrumental monitoring of shore morphology, relying on system of benchmarks used for repeated measures, together with in-field geomorphologic expertise. Measures include direct observations and geodetic leveling onshore and echosounding offshore. Being the most precise method, direct measurements are expensive. The other drawback is that they can't give an overview of long-span tendencies of coastal evolution for prolonged shore sections, which is essential for shore deformation forecast complying with lifetime of structures (usually 30 to 50 years). This is where the importance of the 2nd part, analysis of the different time remote sensing data, becomes decisive. Most important sources of remote sensing data include Corona imagery from 1960s - 70s, aerial photos of different times (but most of them are inaccessible for Russian Arctic coast), Landsat imagery (covering a long time span

Radionuclide inventories have bin estimated for the reactor cores, reactor components, and primary system corrosion products in the former Soviet Union naval reactors dumped at the Abrosimov Inlet, Tsivolka Inlet, Stepovoy Inlet, Techeniye Inlet, and Novaya Zemlya Depression sites in the Kara Sea between 1965 and 1988. For the time of disposal, the inventories are estimated at 17 to 66 kCi of actinides plus daughters and 1695 to 4782 kCi of fission products in the reactor cores, 917 to 1127 kCi of activation products in the reactor components, and 1.4 to 1.6 kCi of activation products in the primary system corrosion products. At the present time, the inventories are estimated to have decreased to 6 to 24 kCi of actinides plus daughters and 492 to 540 kCi of fission products in the reactor cores, 124 to 126 kCi of activation products in the reactor components, and 0.16 to 0.17 kCi of activation products in the primary system corrosion products. All actinide activities are estimated to be within a factor of two

Radionuclide inventories have been estimated for the reactor cores, reactor components, and primary system corrosion products in the former Soviet Union naval reactors dumped at the Abrosimov Inlet, Tsivolka Inlet, Stepovoy Inlet, Techeniye Inlet, and Novaya Zemlya Depression sites in the Kara Sea between 1965 and 1988. For the time of disposal, the inventories are estimated at 69 to 111 kCi of actinides plus daughters and 3,053 to 7,472 kCi of fission products in the reactor cores, 917 to 1,127 kCi of activation products in the reactor components, and 1.4 to 1.6 kCi of activation products in the primary system corrosion products. At the present time, the inventories are estimated to have decreased to 23 to 38 kCi of actinides plus daughters and 674 to 708 kCi of fission products in the reactor cores, 124 to 126 kCi of activation products in the reactor components, and 0.16 to 0.17 kCi of activation products in the primary system corrosion products. Twenty years from now, the inventories are projected to be 11 to 18 kCi of actinides plus daughters and 415 to 437 kCi of fission products in the reactor cores, 63.5 to 64 kCi of activation products in the reactor components, and 0.014 to 0.015 kCi of activation products in the primary system corrosion products.

Kyrgyzstan has a long history of nomadic lifestyle in which pastures play an important role. However, currently the pastures are subject to severe grazing-induced degradation. Deteriorating levels of biomass, palatability and biodiversity reduce the pastures' productivity. To counter this and introduce sustainable pasture management, up-to-date information regarding the ecological conditions of the pastures is essential. This research aimed to investigate the potential of a remote sensing-based methodology to detect changing ecological pasture conditions in the Kara-Unkur watershed, Kyrgyzstan. The relations between Vegetation Indices (VIs) from Landsat ETM+ images and biomass, palatability and species richness field data were investigated. Both simple and multiple linear regression (MLR) analyses, including terrain attributes, were applied. Subsequently, trends of these three pasture conditions were mapped using time series analysis. The results show that biomass is most accurately estimated by a model including the Modified Soil Adjusted Vegetation Index (MSAVI) and a slope factor (R2 = 0.65, F = 0.0006). Regarding palatability, a model including the Enhanced Vegetation Index (EVI), Northness Index, Near Infrared (NIR) and Red band was most accurate (R2 = 0.61, F = 0.0160). Species richness was most accurately estimated by a model including Topographic Wetness Index (TWI), Eastness Index and estimated biomass (R2 = 0.81, F = 0.0028). Subsequent trend analyses of all three estimated ecological pasture conditions presented very similar trend patterns. Despite the need for a more robust validation, this study confirms the high potential of a remote sensing based methodology to detect changing ecological pasture conditions.

Sedimentology and uranium potential of the Inyan Kara Group, near Buffalo Gap, South Dakota. Final report

Sedimentary structures, along with textural and compositional evidence gathered from two stratigraphic sections of the Lower Cretaceous Inyan Kara Group in Calico and Fuson Canyons on the southeastern flank of the Black Hills, suggest the following depositional framework: the basal, Chilson Member of the Lakota Formation consists of a series of upward fining sequences deposited in point-bar and flood-plain environments of a northeasterly flowing, meandering river system. Fluvial sandstones in the Chilson include channel-fill, channel margin, crevasse microdelta and levee facies. The Minnewaste Limestone Member and the lower part of the overlying Fuson Member of the Lakota Formation were deposited in low-energy, lacustrine environments. Flood oriented tidal-delta facies overlain by tidal flat deposits in the upper part of the Fuson Member suggest an earlier incursion of the initial Cretaceous seaway, at least locally, than previously documented in the region. Lower Fall River deposits represent northeast-trending barrier bar and northwest-trending deltaic distributary mouth bar facies, reflecting an increase in sediment supply. Upper Fall River sandstones include distributary mouth bar and lower foreshore deposits. Altered sandstones of the basal Chilson Member and the lower part of the Fuson Member in Calico Canyon contain anomalous values of U 3 O 8 . Fossil wood and bone samples are also enriched in trace elements of U, V, and Mo, suggesting that uranium-bearing solutions might have passed through porous and permeable sandstones of the study area, possibly flowing toward the northeast along Chilson paleochannels

The number of road traffic victims in Japan has been above the level of 10,000 annually during 8 consecutive years, but in 1996 and 1997, it becomes below this level. The casualty of road traffic accidents is found to be occurred during driving and senior persons account for a large part among victims while 55.1% of the case took place at night. As for the countermeasures, it is possible to indicate the regulatory strengthening, advancement of accident investigation and analysis, provision of safety information to the user and research and development of advanced safety vehicle (ASV). Concerning preventive safety, studies on the human recognition, systems for assisting judgement and running and so on can be enumerated. The ASV is in the course of 2nd program that lasts until 2001 with 6 safety research subjects such as prevention, collision, automatic operation, containment of disaster from expanding and so forth. In terms of post-accident safety, remarkable research and development have been conducted on collision by means of dummy and human body, human resistance against injury, air bag for rider protection and child seat, and especially the form comparison of interior materials for head protection apparatus as well as study via simulation, together with commercialization of side bag for reducing head damages. As for car body materials, energy absorption by pillar type elements, use of aluminum materials, resistance comparison and design concept of structural separation and so on are being carried out. 69 refs., 1 fig.

The Arctic is affected by climate change much stronger than other regions of the globe. Permafrost thawing can lead to additional methane release, which enhances the greenhouse effect and warming, as well as changes of Arctic tundra ecosystems. A great part of Siberian Arctic is still unexplored. Ground-based investigations are difficult to be carried out in this area due to it is an out-of-the-way place. So, in spite of the high cost, aircraft-based in-situ measurements can provide a good opportunity to fill up the gap in data on the atmospheric composition over this region. The ninth YAK-AEROSIB campaign was focused on the airborne survey of Arctic regions of West Siberia. It was performed in October 2014. During the campaign, the high-precision in-situ measurements of CO2, CH4, CO, O3, black carbon and aerososls, including aerosol lidar profiles, have been carried out in the Siberian troposphere from Novosibirsk to Kara Sea. Vertical distributions of the above atmospheric constituents will be presented.

Between 1965 and 1981, five objects and six naval reactor pressure vessels (RPVs) from four former Soviet Union submarines and a special container from the icebreaker Lenin, all containing damaged spent nuclear fuel (SNF) were dumped in a variety of containments, at four sites in the Kara Sea. The International Atomic Energy Agency initiated the International Arctic Seas Assessment Project (IASAP) to study the possible health and environmental effects from disposal of these objects. One outcome of the IASAP was an estimation of the radionuclide inventory and their release rates from these objects. A follow-on concern is the ability to detect the radionuclides released into the water column. The work reported here is the feasibility of using the long-lived radionuclides 59 Ni, 99 Tc, and 236 U encased within these objects, to monitor the breakdown of the containments due to corrosion

Prolonged effect of the stratospheric pathway in linking Barents-Kara Sea sea ice variability to the midlatitude circulation in a simplified model

Zhang, Pengfei; Wu, Yutian; Smith, Karen L.

2018-01-01

To better understand the dynamical mechanism that accounts for the observed lead-lag correlation between the early winter Barents-Kara Sea (BKS) sea ice variability and the later winter midlatitude circulation response, a series of experiments are conducted using a simplified atmospheric general circulation model with a prescribed idealized near-surface heating over the BKS. A prolonged effect is found in the idealized experiments following the near-surface heating and can be explicitly attributed to the stratospheric pathway and the long time scale in the stratosphere. The analysis of the Eliassen-Palm flux shows that, as a result of the imposed heating and linear constructive interference, anomalous upward propagating planetary-scale waves are excited and weaken the stratospheric polar vortex. This stratospheric response persists for approximately 1-2 months accompanied by downward migration to the troposphere and the surface. This downward migration largely amplifies and extends the low-level jet deceleration in the midlatitudes and cold air advection over central Asia. The idealized model experiments also suggest that the BKS region is the most effective in affecting the midlatitude circulation than other regions over the Arctic.

The developmental trend of the reduction technology of greenhouse effect gas emission from automobiles was surveyed. Development of low pollution, energy saving and substituting energy vehicles such as electric, methanol and natural gas vehicles is in rapid progress together with performance improvement of conventional gasoline vehicles. For example, since GDI engine directly injects fuel into cylinders, it can control an air/fuel ratio at will, and reduce CO2 emission. Lean burn engine vehicle and hybrid vehicle are also under development. Performance improvement of storage batteries for electric vehicles, in particular, that combined with solar cells, and the practicability of hybrid vehicles are being clarified. Among them, the superiority of fuel cell technology in the future is becoming clear from a general viewpoint, because of its high efficiency and no CO2 emission. As methanol is produced from plants, construction of cyclic energy systems is promising. However, since low emission vehicles are expensive, some policies such as legal obligation and subsidy system are important. 30 refs., 95 figs., 26 tabs.

DEMOSS will develop and demonstrate elements of a marine oil spill detection and prediction system based on satellite Synthetic Aperture Radar (SAR) and other space data. In addition, models for prediction of sea surface pollution drift will be developed and tested. The project implements field experiments to study the effect of artificial crude oil and oil derivatives films on short wind waves and multi-frequency (Ka-, Ku-, X-, and C-band) dual polarization radar backscatter power and Doppler shift at different wind and wave conditions. On the basis of these and other available experimental data, the present model of short wind waves and radar scattering will be improved and tested.A new approach for detection and quantification of the oil slicks/spills in satellite SAR images is developed that can discriminate human oil spills from biogenic slicks and look-alikes in the SAR images. New SAR images are obtained in coordination with the field experiments to test the detection algorithm. Satellite SAR images from archives as well as from new acquisitions will be analyzed for the Black/Caspian/Kara/Barents seas to investigate oil slicks/spills occurrence statistics.A model for oil spills/slicks transport and evolution is developed and tested in ice-infested arctic seas, including the Caspian Sea. Case studies using the model will be conducted to simulate drift and evolution of oil spill events observed in SAR images. The results of the project will be disseminated via scientific publications and by demonstration to users and agencies working with marine monitoring. The project lasts for two years (2007 - 2009) and is funded under INTAS Thematic Call with ESA 2006.

In Experiment I, response of daily purine derivatives (PD) excretion to feed intake in Yerli Kara crossbred (YK-C) cattle on state farms was measured. Animals were fed a mixed diet containing 30% wheat straw and 70% compounded feed. Crude protein and organic matter contents of the diet were 12.4% and 95%, respectively. In Experiment II, spot urine sampling technique was applied at state farm. Four Yerli Kara crossbred bulls with a mean live weight of 211.0 ± 41.3 kg were used. The experimental design, feeding and diet were the same as in Experiment I. The treatments were allocated according to a 4 x 4 Latin Square design. In Experiment III, spot urine sampling technique was applied at smallholder farms. Two to three kg of compound feed (crude protein 12%) containing 65% barley, 25% bran, 6% sunflower seed meal, 3% marmer dust and 1% mineral and vitamin mixture was offered in two parts, one in the morning (0730 h) and the other in the afternoon (1700 h). The ingredients in the compound feed were similar for all animals, but animals in Groups I, II and III received 1 to 2 kg/d of straw (crude protein 3%), grass hay (crude protein 7%), or both straw and grass hay respectively. In Experiment I, a significant correlation (R 2 =0.99) between PD excretion (Y, mmol/d) and digestible organic matter intake, DOMI (X, kg/d) for YK-C cattle was observed (Y = 12.5 + 19.7 X). Moreover, daily PD excretion (mmol/d) was correlated with the PDC index, which was defined as [PD molar concentration] / [Creatinine molar concentration] x kgW 0.75 . In Experiment II, the PDC index increased with level of intake. The coefficient of variation due to time of sampling for uric acid, allantoin, PD, creatinine, total-N, the PDC Index in spot urine samples were less than 5%. In Experiment III, the PDC index were 49.95 ± 13.5, 45.6 ± 13.0, 48.95 ± 15.3 for the three groups respectively. These values were similar to those for 60% intake level in Experiment I. Using the equation DOMI = 344 + 48

Sensitivity of the sea ice concentration over the Kara-Barents Sea in autumn to the winter temperature variability over East Asia

Cho, K. H.; Chang, E. C.

2017-12-01

In this study, we performed sensitivity experiments by utilizing the Global/Regional Integrated Model system with different conditions of the sea ice concentration over the Kara-Barents (KB) Sea in autumn, which can affect winter temperature variability over East Asia. Prescribed sea ice conditions are 1) climatological autumn sea ice concentration obtained from 1982 to 2016, 2) reduced autumn sea ice concentration by 50% of the climatology, and 3) increased autumn sea ice concentration by 50% of climatology. Differently prescribed sea ice concentration changes surface albedo, which affects surface heat fluxes and near-surface air temperature. The reduced (increased) sea ice concentration over the KB sea increases (decreases) near-surface air temperature that leads the lower (higher) sea level pressure in autumn. These patterns are maintained from autumn to winter season. Furthermore, it is shown that the different sea ice concentration over the KB sea has remote effects on the sea level pressure patterns over the East Asian region. The lower (higher) sea level pressure over the KB sea by the locally decreased (increased) ice concentration is related to the higher (lower) pressure pattern over the Siberian region, which induces strengthened (weakened) cold advection over the East Asian region. From these sensitivity experiments it is clarified that the decreased (increased) sea ice concentration over the KB sea in autumn can lead the colder (warmer) surface air temperature over East Asia in winter.

Surveys have been made on the characteristics of environmentally harmonizing automobiles, and the status of development and introduction thereof inside and outside the country. Discussions were given on the possibility of introducing electric automobiles in Japan. In developing environmentally harmonizing automobiles in Japan, works have been executed on low pollution type components such as lean burn engines, electric automobiles, gasoline engine and electric motor hybrid cars, methanol fueled cars, and fuel cell automobiles. Some of them are already in use in spite of their high price. In America, a cooperation project for the next generation cars has been implemented by mobilizing industrial, academic and governmental organizations. Based on the achievements thereof, the car makers have announced their original advanced cars respectively. In the EU, development of low exhaust gas cars and zero emission cars is being carried out jointly by the related industries setting years 2003 to 2005 as the target.

Statistical Modeling of Sea Ice Concentration Using Satellite Imagery and Climate Reanalysis Data in the Barents and Kara Seas, 1979–2012

Full Text Available Extensive sea ice over Arctic regions is largely involved in heat, moisture, and momentum exchanges between the atmosphere and ocean. Some previous studies have been conducted to develop statistical models for the status of Arctic sea ice and showed considerable possibilities to explain the impacts of climate changes on the sea ice extent. However, the statistical models require improvements to achieve better predictions by incorporating techniques that can deal with temporal variation of the relationships between sea ice concentration and climate factors. In this paper, we describe the statistical approaches by ordinary least squares (OLS regression and a time-series method for modeling sea ice concentration using satellite imagery and climate reanalysis data for the Barents and Kara Seas during 1979–2012. The OLS regression model could summarize the overall climatological characteristics in the relationships between sea ice concentration and climate variables. We also introduced autoregressive integrated moving average (ARIMA models because the sea ice concentration is such a long-range dataset that the relationships may not be explained by a single equation of the OLS regression. Temporally varying relationships between sea ice concentration and the climate factors such as skin temperature, sea surface temperature, total column liquid water, total column water vapor, instantaneous moisture flux, and low cloud cover were modeled by the ARIMA method, which considerably improved the prediction accuracies. Our method may also be worth consideration when forecasting future sea ice concentration by using the climate data provided by general circulation models (GCM.

Uranium resources of the Newcastle 1 0 x2 0 Quadrangle, Wyoming and South Dakota were evaluated to a depth of 1500 m (5000 ft) using available surface and subsurface geologic information. Many of the uranium occurrences reported in the literature and in reports of the US Atomic Energy Commission were located, sampled and described. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, were outlined. Areas favorable for uranium deposits in the subsurface were evaluated using gamma-ray logs. Based on surface and subsurface data, two areas have been delineated which are underlain by rocks deemed favorable as hosts for uranium deposits. One of these is underlain by rocks that contain fluvial arkosic facies in the Wasatch and Fort Union Formations of Tertiary age; the other is underlain by rocks containing fluvial quartzose sandstone facies of the Inyan Kara Group of Early Cretaceous age. Unfavorable environments characterize all rock units of Tertiary age above the Wasatch Formation, all rock units of Cretaceous age above the Inyan Kara Group, and most rock units of Mesozoic and Paleozoic age below the Inyan Kara Group. Unfavorable environments characterize all rock units of Cretaceous age above the Inyan Kara Group, and all rock units of Mesozoic and Paleozoic age below the Inyan Kara Group

Full Text Available The second attempt at constitutional organization, called Osnovanije Praviteljstva Sebskago (Establishment of a Serbian Government, was made by Constantine Constantinovich Rodofinikin, a Russian representative of Greek origine, immediatly after his arrival in Serbia (August 2, 1807. It was signed by Karađorđe on August 20, 1807. According to this project, the supreme power in liberated Serbia was to be executed by the Praviteljstvujušči Senat, i.e. a governing senate, composed of three categories of members: military commanders (vojvode, former honorable members of the council (sovjet and elected representatives of the nahiyes (Turkish districts or counties. The first two categories were to be nobles with a lifelong membership in the senate, while the members of the third category were able to achieve nobility only if elected three times into the senate. Karađorđe was to preside over the senate, bearing the title of svetlejši knez, 'sublime prince,' who would have the right of three votes. Rodofinikin did not consider Karađorđe to be an appropriate person to collaborate with. As a leader of the Uprising, responsible for its military success, Karađorđe demanded urgent, concrete and conditionless Russian aid. On the other hand, Karađorđe wanted autonomous and apsolutic power. Rodofinikin in his Establishment of a Serbian Government, gave him only the presidency over the Senate and the right of three votes. According to this Act, Karađorđe's power was neither hereditary, nor for a lifetime. Karađorđe was not at all satisfied with Rodofinikin's document, but he agreed to the Act thinking that it was the necessary price for Russian support. The aim of Rodofinikin, as well as Paulucci, was to ensure Russian influence in Serbia. However, Paulucci wanted to place Russian officers in all of the governing and commanding positions, while Rodofinikin's desire was to create some kind of Serbian aristocracy, faithful to Russia.

The paper presents the results of the joint project carried out in Germany in order to assess the consequences in the marine environment from the dumping of nuclear wastes in the Kara and Barents Seas. The project consisted of experimental work on measurements of radionuclides in samples from the Arctic marine environment and numerical modelling of the potential pathways and dispersion of contaminants in the Arctic Ocean. Water and sediment samples were collected for determination of radionuclide such as 137Cs, 90Sr, 239+240Pu, 238Pu, and 241Am and various organic micropollutants. In addition, a few water and numerous surface sediment samples collected in the Kara Sea and from the Kola peninsula were taken by Russian colleagues and analysed for artificial radionuclides by the BSH laboratory. The role of transport by sea ice from the Kara Sea into the Arctic Ocean was assessed by a small subgroup at GEOMAR. This transport process might be considered as a rapid contribution due to entrainment of contaminated sediments into sea ice, following export from the Kara Sea into the transpolar ice drift and subsequent release in the Atlantic Ocean in the area of the East Greenland Current. Numerical modelling of dispersion of pollutants from the Kara and Barents Seas was carried out both on a local scale for the Barents and Kara Seas and for long range dispersion into the Arctic and Atlantic Oceans. Three-dimensional baroclinic circulation models were applied to trace the transport of pollutants. Experimental results were used to validate the model results such as the discharges from the nuclear reprocessing plant at Sellafield and subsequent contamination of the North Sea up the Arctic Seas

Drastic changes in the distribution of branched tetraether lipids in suspended matter and sediments from the Yenisei River and Kara Sea (Siberia): Implications for the use of brGDGT-based proxies in coastal marine sediments

The distribution of branched glycerol dialkyl glycerol tetraethers (brGDGTs) in soils has been shown to correlate with pH and mean annual air temperature. Because of this dependence brGDGTs have found an application as palaeoclimate proxies in coastal marine sediments, based on the assumption that their distribution is not altered during the transport from soils to marine systems by rivers. To study the processes acting on the brGDGT distributions, we analysed the full suite of brGDGTs, including the recently described 6-Me brGDGTs, in both the suspended particulate matter (SPM) of the Siberian Yenisei River and the SPM and sediments of its outflow in the Kara Sea. The brGDGT distribution in the SPM of the Yenisei River was fairly constant and characterized by high abundances of the 6-Me brGDGTs, reflecting their production at the neutral pH of the river water. However, the brGDGT distribution showed marked shifts in the marine system. Firstly, in the Yenisei River Mouth, the fractional abundance of the 6-Me brGDGTs decreases sharply. The brGDGT signature in the Yenisei River Mouth possibly reflects brGDGTs delivered during the spring floods that may carry a different distribution. Also, coastal cliffs were shown to contain brGDGTs and to influence especially those sites without major river inputs (e.g. Khalmyer Bay). Further removed from the river mouth, in-situ production of brGDGTs in the marine system influences the distribution. However, also the fractional abundance of the tetramethylated brGDGT Ia increases, resulting in a distribution that is distinct from in-situ produced signals at similar latitudes (Svalbard). We suggest that this shift may be caused by preferential degradation of labile (riverine in-situ produced) brGDGTs and the subsequent enrichment in less labile (soil) material. The offshore distribution indeed agrees with the brGDGT distribution encountered in a lowland peat. This implies that the offshore Kara Sea sediments possibly carry a soil

"My Favourite Day Is Sunday": Community Perceptions of (Drug-Resistant Tuberculosis and Ambulatory Tuberculosis Care in Kara Suu District, Osh Province, Kyrgyzstan.

Directory of Open Access Journals (Sweden)

Doris Burtscher

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

Results of the Edgemont detailed geochemical survey are reported. Field and laboratory data are presented for 109 groundwater and 419 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are given. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Groundwaters containing greater than or equal to 7.35 ppB uranium are present in scattered clusters throughout the area sampled. Most of these groundwaters are from wells drilled where the Inyan Kara Group is exposed at the surface. The exceptions are a group of samples in the northwestern part of the area sampled and south of the Dewey Terrace. These groundwaters are also produced from the Inyan Kara Group where it is overlain by the Graneros Group and alluvium. The high uranium groundwaters along and to the south of the terrace are characterized by high molybdenum, uranium/specific conductance, and uranium/sulfate values. Many of the groundwaters sampled along the outcrop of the Inyan Kara Group are near uranium mines. Groundwaters have high amounts of uranium and molybdenum. Samples taken downdip are sulfide waters with low values of uranium and high values of arsenic, molybdenum, selenium, and vanadium. Stream sediments containing greater than or equal to 5.50 ppM soluble uranium are concentrated in basins draining the Graneros and Inyan Kara Groups. These values are associated with high values for arsenic, selenium, and vanadium in samples from both groups. Anomalous values for these elements in the Graneros Group may be caused by bentonite beds contained in the rock units. As shown on the geochemical distribution plot, high uranium values that are located in the Inyan Kara Group are almost exclusively draining open-pit uranium mines.

The indicated migration behavior of radionuclides is characteristic of the Yenisey Gulf and the adjacent part of the Kara Sea also. We made similar conclusions when studying the migration behavior of Cs-137, Pu-239,240, and Sr-90 in the Kiev reservoir (1987). The formation of radioactive flood-land deposits is provided by rapid deposition of suspended material in stagnant zones during periodical flood. Humus compounds contribute significantly to accumulation of radionuclides in the flood-land deposits and bottom sediments, which is supported by the observed correlation between the radionuclide (Pu, Am, Eu) and total organic carbon distributions in them. Radiochemical analysis of separate fractions showed that about 20% of Pu and Am are associated with the organic fraction: Pu is nearly equally distributed between humic and fulvic acid fractions, whereas Am is preferentially associated with the fulvic acid fraction (the most mobile fraction of humus matter). It was demonstrated in model experiments that the calcium-hydrocarbonate type of water of the Yenisey River causes suppression of formation of mobile fulvate complexes of hydrolyzable radionuclides and, therefore, their transfer into the aqueous phase. In combination with the observed very high distribution coefficients of the radionuclides and low content of their mobile geochemical forms in flood-land deposits of the Yenisey River this suggest that they cannot contribute somewhat significantly to the secondary radioactive contamination of the river water by all mechanisms except migration by mechanical transfer.

Ribonuclease activity of buckwheat plant (Fagopyrum esculentum cultivars with different sensitivities to buckwheat burn virus

Directory of Open Access Journals (Sweden)

2014-06-01

Full Text Available Ribonucleases (RNases are present in base-level amounts in intact plants, but this level is able to increase greatly under stress conditions. The possible cause for such an increase is protection against plant RNA-virus attack. Buckwheat burn virus (BBV is a highly virulent pathogen that belongs to Rhabdoviridae family. In our study, we have analyzed the correlation between RNase activity and resistance of different buckwheat cultivars to BBV infection. Two cultivars, Kara-Dag and Roksolana, with different sensitivities to BBV have been used. Kara-Dag is a cultivar with medium sensitivity to virus and Roksolana is a tolerant cultivar. It has been shown that the base level of RNase activity in Roksolana cultivar was in most cases higher than the corresponding parameter in Kara-Dag cultivar. Both infected and uninfected plants of Roksolana cultivar demonstrated high RNase activity during two weeks. Whereas infected plants of Kara-Dag cultivar demonstrated unstable levels of RNase activity. Significant decline in RNase activity was detected on the 7th day post infection with subsequent gradual increase in RNase activity. Decline of the RNase activity during the first week could promote the virus replication and therefore more successful infection of upper leaves of plants. Unstable levels of RNase activity in infected buckwheat plants may be explained by insufficiency of virus-resistant mechanisms that determines the medium sensitivity of the cultivar to BBV. Thus, plants of buckwheat cultivar having less sensitivity to virus, displayed in general higher RNase activity.

Volatile organic compounds (VOCs) play various roles in plant-plant interactions, and constitutively produced VOCs might act as a cue to sense neighbouring plants. Previous studies have shown that VOCs emitted from the barley (Hordeum vulgare) cultivar 'Alva' cause changes in biomass allocation in plants of the cultivar 'Kara'. Other studies have shown that shading and the low red:far-red (R:FR) conditions that prevail at high plant densities can reduce the quantity and alter the composition of the VOCs emitted by Arabidopsis thaliana, but whether this affects plant-plant signalling remains unknown. This study therefore examines the effects of far-red light enrichment on VOC emissions and plant-plant signalling between 'Alva' and 'Kara'. The proximity of neighbouring plants was mimicked by supplemental far-red light treatment of VOC emitter plants of barley grown in growth chambers. Volatiles emitted by 'Alva' under control and far-red light-enriched conditions were analysed using gas chromatography-mass spectrometry (GC-MS). 'Kara' plants were exposed to the VOC blend emitted by the 'Alva' plants that were subjected to either of the light treatments. Dry matter partitioning, leaf area, stem and total root length were determined for 'Kara' plants exposed to 'Alva' VOCs, and also for 'Alva' plants exposed to either control or far-red-enriched light treatments. Total VOC emissions by 'Alva' were reduced under low R:FR conditions compared with control light conditions, although individual volatile compounds were found to be either suppressed, induced or not affected by R:FR. The altered composition of the VOC blend emitted by 'Alva' plants exposed to low R:FR was found to affect carbon allocation in receiver plants of 'Kara'. The results indicate that changes in R:FR light conditions influence the emissions of VOCs in barley, and that these altered emissions affect VOC-mediated plant-plant interactions. © The Author 2015.

At that, it should be noted, that hydrocarbons are widely spread in lithosphere and create steady geochemical background, variations are caused here by specifics of initial organic matter, conditions of its accumulation and transformation. The basis of the study are the samples of sea water and deep sea sediments (more than 600 stations), collected in western sector of Arctic region (Pechora, Barents and Kara seas) during the scientific-research expeditions of FSBI "VNIIOkeangeologia" for the period 2000-2010. Total content of aromatic hydrocarbons was defined by spectrofluorometric method using analyzer «FLUORAT-Panorama-02». Certification of data was performed on representative samples based on contents and molecule structure of polycyclic aromatic hydrocarbons using GC-MS (Agilent 5973/6850 GC-MS System). Results of spectrofluorometric analysis of lipid fraction of organic matter of bottom sediments allowed to define specific parameters, which characterize various lithofacies groups of sediments. Thus, sandy residues are characterized by low level of aromatic hydrocarbons (ca. 4.3 μg/g) with prevalence of bi- and tri-aromatic compounds (λmax 270-310 nm). This correlates with low sorption capacity of coarse-grained sediments and absence of organic-mineral component, containing the breakdown products of initial organic matter. Tetra- and penta- aromatic structures prevail in clay sediments (ca. 13.0 μg/g), which are typical components of lipid fraction of organic matter of post sedimentation and early diagenetic stages of transformation. At that, changes of spectral characteristic of sediments in stratigraphic sequence completely reflect processes of diagenetic transformation of organic matter, including

With problems inherent to clean energy vehicles such as cruising distance, fuel supply and fuel consumption, ACEVs (advanced clean energy vehicles) are in demand featuring both low pollution and high efficiency compatibly. This paper explains the fiscal 2000 results of development. The target is, by using oil-alternative fuel, to reduce driving energy consumption and carbon dioxide emission to less than half and to control the life cycle cost (total of manufacturing cost, operating cost, fuel cost, etc.) to not more than twice as much as those of conventional vehicles. As ACEVs, an ANG (adsorbed natural gas) engine and flywheel battery mounted passenger car was selected, as were a CNG ceramics engine and capacitor mounted truck, CNG engine and lithium-ion battery mounted truck, LNG engine and capacitor mounted bus, and a DME engine and capacitor mounted bus. All are hybrid systems with an energy saving device. In the research of synthetic fuels, the results of the studies were summarized including the effect of various synthetic light oils on engine performance, fuel characteristics, effect of PM grain size and the optimum properties.

Relative Role of Horizontal and Vertical Processes in Arctic Amplification

2017-12-01

The physical mechanism of Arctic amplification is still controversial. Specifically, relative role of vertical processes resulting from the reduction of sea ice in the Barents-Kara Seas is not clearly understood in comparison with the horizontal advection of heat and moisture. Using daily data, heat and moisture budgets are analyzed during winter (Dec. 1-Feb. 28) over the region of sea ice reduction in order to delineate the relative roles of horizontal and vertical processes. Detailed heat and moisture budgets in the atmospheric column indicate that the vertical processes, release of turbulent heat fluxes and evaporation, are a major contributor to the increased temperature and specific humidity over the Barents-Kara Seas. In addition, greenhouse effect caused by the increased specific humidity, also plays an important role in Arctic amplification. Horizontal processes such as advection of heat and moisture are the primary source of variability (fluctuations) in temperature and specific humidity in the atmospheric column. Advection of heat and moisture, on the other hand, is little responsible for the net increase in temperature and specific humidity over the Barents-Kara Seas.

Cultural Memory on "Great" People in a "Small" Town: The Perception of King Alexander Karađorđević and Marshal Josip Broz Tito in the Cultural Memory of Samobor

Full Text Available Starting from the thesis that ''history is written by the winners”, ''mainstream'' history can be under¬stood as the revised and politically instrumentalized means of a certain nation's ''cultural'' memory, which some consider to be a ''history of selective memo¬ri¬zation and selective forgetfulness''. Most approaches in con¬temporary Croatian historiography which are focu¬sed on the historical periods of monarchist and socialist Yugoslavia use national-level themes as their starting point. A similar preoccupation is also present in those historiographical approaches which are focused on the problems of analyzing and understanding how collective memories are constructed. However, our aim here is to move from the ''big'' themes to a ''small'' (local setting. In this context, Samobor, a small Croatian urban centre, is going to serve us as the basis for analyzing in which way two Yugoslav rulers – King Alexander Karađorđević and Marshal Josip Broz Tito – were perceived on the local level. By analyzing the relevant archival sources as well as contemporary periodicals, we seek to un¬der¬stand the ways in which local authorities and elites, from their position of social power and status, received the mentioned rulers during their visits, and in which ways did they honour and commemorate these high-profile guests. Through this analysis, we hope to gain a better understanding of the process of the creation of local social memory, the constitution of memorial and cul¬tural patterns, and their key cultural elements and me¬anings, which are often torn apart during periods of social and political upheaval, only to be reconstituted by recombining the same key cultural and social elements while simultaneously encompassing new actors. In other words, the focus of our analysis will be on tracing the collective memory of the population of Samobor to¬wards two ''great leaders''.

Trends in aerosol optical depth in the Russian Arctic and their links with synoptic climatology

Shahgedanova, Maria; Lamakin, Mikhail

2005-01-01

Temporal and spatial variability of aerosol optical depth (AOD) are examined using observations of direct solar radiation in the Eurasian Arctic for 1940-1990. AOD is estimated using empirical methods for 14 stations located between 66.2 deg N and 80.6 deg N, from the Kara Sea to the Chukchi Sea. While AOD exhibits a well-known springtime maximum and summertime minimum at all stations, atmospheric turbidity is higher in spring in the western (Kara-Laptev) part of the Eurasian Arctic. Between June and August, the eastern (East Siberian-Chukchi) sector experiences higher transparency than the western part. A statistically significant positive trend in AOD was observed in the Kara-Laptev sector between the late 1950s and the early 1980s predominantly in spring when pollution-derived aerosol dominates the Arctic atmosphere but not in the eastern sector. Although all stations are remote, those with positive trends are located closer to the anthropogenic sources of air pollution. By contrast, a widespread decline in AOD was observed between 1982 and 1990 in the eastern Arctic in spring but was limited to two sites in the western Arctic. These results suggest that the post-1982 decline in anthropogenic emissions in Europe and the former Soviet Union has had a limited effect on aerosol load in the Arctic. The post-1982 negative trends in AOD in summer, when marine aerosol is present in the atmosphere, were more common in the west. The relationships between AOD and atmospheric circulation are examined using a synoptic climatology approach. In spring, AOD depends primarily on the strength and direction of air flow. Thus strong westerly and northerly flows result in low AOD values in the East Siberian-Chukchi sector. By contrast, strong southerly flow associated with the passage of depressions results in high AOD in the Kara-Laptev sector and trajectory analysis points to the contribution of industrial regions of the sub-Arctic. In summer, low pressure gradient or

Transport of contaminants by Arctic sea ice and surface ocean currents

1995-01-01

Sea ice and ocean currents transport contaminants in the Arctic from source areas on the shelves, to biologically active regions often more than a thousand kilometers away. Coastal regions along the Siberian margin are polluted by discharges of agricultural, industrial and military wastes in river runoff, from atmospheric deposition and ocean dumping. The Kara Sea is of particular concern because of deliberate dumping of radioactive waste, as well as the large input of polluted river water. Contaminants are incorporated in ice during suspension freezing on the shelves, and by atmospheric deposition during drift. Ice releases its contaminant load through brine drainage, surface runoff of snow and meltwater, and when the floe disintegrates. The marginal ice zone, a region of intense biological activity, may also be the site of major contaminant release. Potentially contaminated ice from the Kara Sea is likely to influence the marginal ice zones of the Barents and Greenland seas. From studies conducted to date it appears that sea ice from the Kara Sea does not typically enter the Beaufort Gyre, and thus is unlikely to affect the northern Canadian and Alaskan margins

Stepovogo fjord, located on the Eastern coast of Novaya Zemlya, is one of the most important former Soviet Union dumping sites for radioactive waste in the Kara Sea. In addition to some 2000 dumped containers with conventional radioactive wastes, the nuclear submarine K-27 was dumped in Stepovogo fjord with two reactors loaded with spent nuclear fuel (SNF).Joint Russian and Norwegian surveys of the marine environment in Stepovogo fjord were first conducted in 1993 and 1994. In accordance with the working plan of the Joint Russian-Norwegian Expert Group on the Investigation of Radioactive Contamination in the Northern Areas, a follow up expedition into the radioecological status of Stepovogo fjord was carried out in August and September of 2012 onboard the R.V. 'Ivan Petrov' of the Roshydromet Northern Department. Investigations carried out in Stepovogo fjord during the expedition included: Sonar surveys, ROV inspections and in situ gamma measurements of the dumped nuclear submarine K-27 and dumped containers with radioactive waste Sampling of seawater, bottom sediments and marine biota. Results of the analysis of marine environmental samples performed by Russia, Norway and the IAEA, are presented and discussed in the paper. Preliminary measurements on surface sediments and water samples showed that the level of {sup 137}Cs contamination was generally low. However, slightly enhanced levels of {sup 137}Cs were detected in bottom seawater and sediment collected in the area with dumped containers. Measurements taken around the dumped nuclear submarine K-27 did not indicate any leakage of radioactive substances from the submarine. A similar picture for the level of radioactive contamination in Stepovogo fjord was observed in the first joint Russian-Norwegian expedition in 1993-94. (authors)

Geographical variation of organochlorine pesticides (OCPs) was studied in blood samples from 90 adult female polar bear (Ursus maritimus) from Svalbard, Franz Josef Land, Kara Sea, East-Siberian Sea and Chukchi Sea. In all regions, oxychlordane was the dominant OCP. Regional differences in mean levels of HCB, oxychlordane, trans-nonachlor, ??-HCH, ??-HCH and p,p???-DDE were found. The highest levels of oxychlordane, trans-nonachlor and DDE were found in polar bears from Franz Josef Land and Kara Sea. HCB level was lowest in polar bears from Svalbard. Polar bears from Chukchi Sea had the highest level of ??- and ??-HCH. The lowest ??-HCH concentration was found in bears from Kara Sea. In all the bears, ???HCHs was dominated by ??-HCH. The geographical variation in OCP levels and pattern may suggest regional differences in pollution sources and different feeding habits in the different regions. Polar bears from the Western Russian Arctic were exposed to higher levels of chlordanes and p,p???-DDE than polar bears from locations westwards and eastwards from this region. This may imply the presence of a significant pollution source in the Russian Arctic area. The study suggests that the western Russian Arctic is the most contaminated region of the Arctic and warrants further research. ?? 2002 Elsevier Science B.V. All rights reserved.

Aquilaria malaccensis or karas is the principal source of gaharu resin, which is used in many cultures for incense, perfumes and traditional medicines. The species is mainly propagated conventionally through seeds, cuttings and graftings. Propagation by seeds is usually a reliable method for other forest species, but for karas, this technique is inadequate to meet the current demand of seedling supplies. This is principally due to its low seed viability, low germination rate, delayed rooting of seedlings, long life-cycle and rare seed production. Tissue culture has several advantages over conventional propagation, especially for obtaining large number of uniform and high-yielding plantlets or clones. This paper presents the current progress on mass-propagation of Aquilaria malaccensis seedlings through tissue culture technique at Nuclear Malaysia. (author)

For the purpose of establishing the basement technology relating to photoreactive materials which make remarkably higher density and larger capacity of the information recording possible, the following were made for photochromic materials and PHB materials: elucidation of the photoreaction mechanism, development of materials, development of material processing/structure technology and development of evaluation technology. The target is to establish the technology of the multiplex recording which is applicable to the super-high density recording in relation to PHB materials/organic photochromic materials which have potentiality of photon-mode recording. PHB materials were developed which have potentiality of 600 wavelength multiple recording and 5 electric field multiple recording in 4.2K and 9 wavelength multiple recording in 77K. Photochromic materials were developed which have high sensitivity and preservation stability and have potentiality of 10 wavelength multiple recording at room temperature. A new photo-recording method was found out by which the orientation of liquid crystal is photo-controlled and potentiality of the multiple polarization was shown. Moreover, the fabrication was successfully made of PHB materials and photochromic materials which make non-destructive readout operation of more than 10{sup 4} times possible. (NEDO)

The hybrid electric vehicle (HEV) has been attracting attention as a clean energy vehicle, because it will potentially show higher fuel economy and release smaller quantities of exhaust emissions than the conventional internal combustion engine, and also will be potentially advantageous over the electric vehicle in that it needs no charging infrastructures and less cost. However, there are many types of hybrid vehicle systems, and, for them to be commercialized on a large scale, it is urgently necessary to establish the fuel economy measurement method. The 1998 R and D efforts were directed to analysis of the effects of the hybrid-characteristic factors (SOC of the propulsion battery and regenerative braking) on fuel economy and exhaust emissions. As a result, it is found that changed SOC before and after the tests must be corrected to determine fuel economy and that it is possible. The method for measuring the effects of regenerative braking should be further developed, because the data collected while the vehicle is running on road and on a two-wheel chassis dynamometer are not clearly distinguished from each other. The exhaust emissions are also sensitive to the changed SOC, correction for which, however, is not as easy as that for fuel economy. (NEDO)

As to the technology to reduce vehicle weight with the aim of energy conservation, survey was made of the present situation and technical subjects. Further survey was conducted on the applicability of ferrous and aluminum mesoscopic system control materials (super metal) under development. The application of high-tensile steel to vehicles is rapidly being developed as a means of weight reduction. To increase a rate of the use of high-tensile steel, limits of forming, characteristic improvement and rigidity need to be removed. Further, concerning the application of aluminum, subjects are press formability and joining. In regard to the development of ferrous super metal, characteristics with high ductility were obtained despite of such high strength as tensile strength of 930MPa, uniform elongation of 17%, and total elongation of 27%, which indicated that the super metal has an applicability to vehicle use thin steel sheets. The ferrous super metal, which enables the production of high-tensile steel sheet with no use of much alloy elements, is a material with high recycling ability. The aluminum super metal has also an applicability to vehicles. (NEDO)

The Vitality of Kabiye in Togo Zur Überlebensfähigkeit des Kabiye in Togo

Full Text Available In Togo, speakers of Kabiye have been in contact with the speak¬ers of Ewe for several decades due to migration. As a result of this language contact, many members of the Kabiye speech community have become bilingual in Kabiye and Ewe. There have been a number of claims that Kabiye “est une langue en péril” (Aritiba 1993: 11. These claims have been based mainly on the observation of Kabiye speakers in Lomé and other major cities, where younger speakers seem to be losing their mother tongue to the benefit of Ewe. However, the extent of the loss of Kabiye is not well known because no extensive sociolinguistic study has been carried out among Kabiye speakers in these areas, and more specifically, in major Kabiye-speaking areas. The current study which has been carried out in Kara, the major Kabiye-speaking city and Awidina, a Kabiye village of the prefecture of Kara, fills the gap. The paper examines Kabiye speakers’ reports of patterns of language use in these areas of the Kabiye community. Seit einigen Jahrzehnten leben Kabiye-sprachige Migranten in Togo in Kontakt mit der Ewe-sprachigen Bevölkerung. Im Ergebnis dieses Sprachkontakts sind viele Angehörige der Kabiye-Sprachgemeinde bilingual und kombinieren Kabiye und Ewe. Kabiye wird inzwischen vielfach als sterbende Sprache angesehen. Diese Einschätzungen beruhen aber vor allem auf der Beobachtung von Kabiye-Sprachigen in Lomé und anderen großen Städten, wo die jungen Leute nach und nach ihre Muttersprache zugunsten von Ewe aufgeben. Dennoch ist über das Ausmaß des Verschwindens von Kabiye wenig bekannt, denn bislang gibt es keine extensive Studie unter Kabiye-Sprachigen in diesen Gebieten, insbesondere aber auch keine für Regionen, in denen Kabiye die wichtigste Sprache darstellt. Die vorliegende Studie, die in Kara, der wichtigsten Kabiye-sprachigen Stadt, und in Awidina, einem Kabiye-Dorf in der Präfektur Kara, durchgeführt wurde, will diese Lücke schließen. Der Autor

Marine Isotope Stage (MIS) M2 ( 3.3 Ma) in the southern hemisphere: constraining the climatic drivers of a short-term glaciation event during the Pliocene warm Period.

Global climate was characterized by intriguing climate variability during the Late Pliocene (3.6 to 2.59 Ma): a brief (<100 kyr) but intense glaciation (MIS M2) interrupted the relatively warm climate state around 3.3 Ma. Until today, different hypotheses exist to explain why this glaciation event was so intense, and why the global climate system returned to warm Pliocene conditions relatively quickly. One of these proposed mechanisms is a reduced equator-to-pole heat transfer, in response to a tectonically reduced Indonesian Throughflow (ITF; De Schepper et al., 2014; Karas et al., 2011a, b). However, the scarcity of orbital-scale continuous climate archives in the outflow of the Indonesian Seaway hampers testing this hypothesis. To assess the supposed relationship between mid-Pliocene glaciations and latitudinal heat transport through the Indonesian Throughflow, we constructed a 3-kyr resolution planktonic δ18OG.sacculiferrecord for the 3.9 - 2.7 Ma interval from Site U1463 (18°59'S, 117°37'E; Northwestern Australian Shelf; IODP Expedition 356 "Indonesian Throughflow"). The U1463 oxygen isotope record concurs exceptionally well with the sea surface temperature (SST) record from Site 806 (0°19'N, 159°22'E) in the West Pacific Warm Pool (Wara et al., 2005), even during MIS M2. Hence, Site U1463 suggests an uninterrupted ITF signal during Pliocene glaciations. Surprisingly though, the U1463 δ18OG.sacculifer record exhibits a 0.5‰ offset with the nearby Site 763 record (20°35'S, 112°12'E) around MIS M2. This implies that Site 763, which lies a bit further offshore than U1463, fits better with Indian Ocean SST records (e.g. Site 214; Karas et al., 2009) across MIS M2. In conclusion, the U1463 data reveal that heat-transport through the Indonesian Throughflow did not shut down completely during MIS M2. However, its intensity decreased during MIS M2, causing Site 763 to temporarily reflect an Indian Ocean, rather than an ITF signal. References De Schepper, S

Analysis was made by using the life cycle assessment method for the purpose of saving energy in the use stage of automobiles. Life cycle energy was calculated for cases of adopting direct fuel injection and non-stage transmission (CVT) in the currently used gasoline fueled cars. The calculation was performed with respect to each stage of raw material manufacturing, car fabrication, internal energy manufacturing, driving and disposal. Adoption of direct fuel injection and CVT technologies results in reducing the life cycle energy to about 30% in the use stage and little less than 30% on the whole. Stopping the idling operation will reduce the energy in the use stage by about 40%. Adoption of electric vehicles will result in energy reduction of 30% to 35% as compared with gasoline fueled cars. Since fuel consumption improves with increasing average car speed, energy consumption will be improved by about 30% if the current average car speed in the Tokyo Metropolitan area of 19 km/h is improved to the national average level. Improving the driving environments is important. Driving methods with less often quick starting and quick acceleration can save energy. Combinations of policies are desired, such as improvements in the currently used gasoline fueled vehicles, introduction of substitution fuel driven vehicles, and improvements in driving environments. 4 refs., 10 figs., 3 tabs.

Analysis of automotive tire construction. Jidosha tire no kozo kaiseki

Energy Technology Data Exchange (ETDEWEB)

Ishihara, K. (Toyo Tire and Rubber Co. Ltd., Osaka (Japan))

1993-06-15

This paper introduces features and trends of analyzing performance and construction of automotive tires. Tires are demanded of high durability, high motion performance, good comfort performance for vibration and noise, and low fuel consumption performance. A feature of analyzing the construction is to execute a modelling assuming that a tire has air-rigid flexible structure and rubber materials show hyperelastic behavior, hypothesizing a strain energy density function. In addition, a tire is highly incompressible. Visco elasticity and anti-friction performance are also important points. Rubber and cord layers have elastic characteristic of three-dimensional perpendicular anisotropy as well as non-linearity with which characteristics change according to transformation. A structural analysis must cover from static analysis to steady dynamic analysis, non-steady dynamic analysis, and eigenvalue analysis. Thermal analysis of tires simulates phenomena by combining dynamical analysis with thermal analysis. Super-computers have now come to be used for formulating equilibrium equations using finite element methods, developing finite elements, and performing heat or visco elasticity analysis and applied analysis. 35 refs., 3 figs.

According to the trend of car suspensions announced in 1989, not only sports cars but also sedans have extensively applied a multi-link type and a double-wishbone type which are to improve operation stability and comfortableness by reexamining all their fundamental structures. Active suspensions with electronic control have been put to practical use and adopted for the first time to mass-produced cars such as INFINITI'' and CELICA''. Concerning steerings, most types of light cars are now equipped with power steerings. Moreover, application of air bags has increased, and safety has been improved by commercialization of the first mechanical air bags in addition to the conventional electrical ones. As for brakes, more anti-lock brakes have been used for 4WD cars and low-displacement cars. Motorcars with a traction control system have consequently increased. Thus both the anti-lock brakes and the traction control system are contributing to the improvement in safety. 17 figs., 2 tabs.

Establishment of Aquilaria malaccensis Callus, cell suspension and adventitious root systems

International Nuclear Information System (INIS)

Norazlina Noordin; Rusli Ibrahim

2010-01-01

Aquilaria malaccensis is a tropical forest tree from the family Thymelaeaceae, an endangered forest species and was listed in CITES since 1995. Locally known as Pokok Karas, this tree produces agar wood or gaharu, a highly valuable, resinous and fragrant forest product. Karas has been highly recognized for its vast medicinal values and gaharu has been widely use for perfumery, incense and religious purposes. The phyto chemical studies of agar wood showed that Sesqui terpenoid and Phenyl ethy chromone derivatives are the principal compounds that have anti allergic and anti microbe activities. Cell and organ culture systems provide large scale production of biomass and offers feasibilities for the production of secondary metabolites. This paper describes the work done for establishing reproducible systems for callus initiation and production of cell suspension cultures as well as production of adventitious roots that will later be amenable for the production of secondary metabolites of A. malaccensis. Hence, further manipulation with Methyl Jasmonate, a chemical elicitor could be done to induce secondary metabolites using callus, cell suspension and adventitious roots systems. (author)

Survey/analysis were made on the details of the plan on the leading introduction of clean energy vehicle by 632 transporters who applied for the project on promotion of clean energy vehicle in FY 2001. As a result of the survey, the following were made clear. The clean energy vehicles to be planned to be introduced by transporters are all natural gas vehicles. The transporters planning the leading introduction are mostly in large cities and are spreading also in the periphery. Fifty three percent of the transporters predicts that the predicted average running distance of the clean energy vehicle to be introduced is the same as those of the vehicles they owns, and 39% predicts that it is shorter. About the form of utilization, they use it overwhelmingly for the regional collection/delivery. It is considered that the improvement in running distance per 1 fuel filling of clean energy vehicle will contribute to the spread. Fuel supply stations that the clean energy cars to be introduced use concentrate in the good location. It is necessary to strongly promote preparation of the infrastructure. (NEDO)

The Effect of Chemical, Biological and Organic Nutritional Treatments on Sunflowers Yield and Yield Components under the Influence of Water Deficit Stress

Full Text Available Introduction To achieve the higher economic yield of crop plants, supplying enough nutrients to plants is very important. Moreover, nutrient uptakes by plants is influenced by the soil water contents. However, nowadays chemical fertilizer application is important agronomic factor that has significant effects on growth and quantity and quality of final yield, but traditional nutrient management and excessive use of chemical fertilizers may cause the environmental problems such as contamination of soil and water resources, low quality of agricultural products and reduction of soil fertility. These factors have drawn attention to health and ecological sustainable farming systems (Sharma, 2002. In this context, usage of organic and biological products for plant nutrition is considered as one of the solutions to achieve the goals of sustainable agriculture. Materials and methods To evaluate the effect of various feeding systems on yield and yield components of sunflower (Helianthus annuus L. under the influence of water deficit stress, a split-plot experiment based on randomized complete block design with three replications, was carried out in the Agricultural Faculty of Bu-Ali Sina University during the growing season of 2013-2014.

Plutonium in the arctic marine environment--a short review.

Science.gov (United States)

Skipperud, Lindis

2004-06-18

Anthropogenic plutonium has been introduced into the environment over the past 50 years as the result of the detonation of nuclear weapons and operational releases from the nuclear industry. In the Arctic environment, the main source of plutonium is from atmospheric weapons testing, which has resulted in a relatively uniform, underlying global distribution of plutonium. Previous studies of plutonium in the Kara Sea have shown that, at certain sites, other releases have given rise to enhanced local concentrations. Since different plutonium sources are characterised by distinctive plutonium-isotope ratios, evidence of a localised influence can be supported by clear perturbations in the plutonium-isotope ratio fingerprints as compared to the known ratio in global fallout. In Kara Sea sites, such perturbations have been observed as a result of underwater weapons tests at Chernaya Bay, dumped radioactive waste in Novaya Zemlya, and terrestrial runoff from the Ob and Yenisey Rivers. Measurement of the plutonium-isotope ratios offers both a means of identifying the origin of radionuclide contamination and the influence of the various nuclear installations on inputs to the Arctic, as well as a potential method for following the movement of water and sediment loads in the rivers.

Enhanced ice sheet growth in Eurasia owing to adjacent ice-dammed lakes.

Krinner, G; Mangerud, J; Jakobsson, M; Crucifix, M; Ritz, C; Svendsen, J I

Large proglacial lakes cool regional summer climate because of their large heat capacity, and have been shown to modify precipitation through mesoscale atmospheric feedbacks, as in the case of Lake Agassiz. Several large ice-dammed lakes, with a combined area twice that of the Caspian Sea, were formed in northern Eurasia about 90,000 years ago, during the last glacial period when an ice sheet centred over the Barents and Kara seas blocked the large northbound Russian rivers. Here we present high-resolution simulations with an atmospheric general circulation model that explicitly simulates the surface mass balance of the ice sheet. We show that the main influence of the Eurasian proglacial lakes was a significant reduction of ice sheet melting at the southern margin of the Barents-Kara ice sheet through strong regional summer cooling over large parts of Russia. In our simulations, the summer melt reduction clearly outweighs lake-induced decreases in moisture and hence snowfall, such as has been reported earlier for Lake Agassiz. We conclude that the summer cooling mechanism from proglacial lakes accelerated ice sheet growth and delayed ice sheet decay in Eurasia and probably also in North America.

Valyaev, A.N.; Stepanets, O.V.

Full text: Intensive and insufficiently controlled human industrial activities, ignoring regional geological and geochemical processes, resulted in considerable chemical pollution and radioactive contamination of these river's basins, where some large nuclear power plants, uranium and chemical enterprises, oil and gas productions are also located. This epidemiological and environmental situation aggravated further after USSR collapse and the establishment of new independent states due to lack of the appropriate environmental monitoring in those countries and on their near-border areas in particular, that contributed to further aggravation of the political tension and economic destabilization between transboundary countries. The environmental situation here is one of most unfavorable among world water ecosystems. In recent years different pollutants (radionuclides, toxins, organic substances and heavy metals) activate reduction processes in bottom sediments, that lead to changes in sulfur and carbon cycles, the oxygen deficit in water, to eutrophication of water reservoirs and their biological degradation. Today the development of total environmental monitoring systems is clearly necessary for operative current control, ensuring preparedness and prediction of any potential emergencies of global and local scales and their long-term effects. The objectives for presented monitoring systems are to: (1)study sources and mechanisms of chemical pollution and radioactive contamination of water basins of Volga (the largest river in Europe and Russia), Terek and Ural rivers flowed into Caspian Sea, and Ob, Irtysh and Tom ones, flowed into Kara Sea in Arctic Ocean within RF territory; (2) develop the well-ground database (DB) on contamination; (3) the using of the obtained results for the operative current trans boundary control, monitoring and protection of freshwater resources; (4) modeling of pollutant's migration.

Plutonium in the Arctic Marine Environment — A Short Review

Directory of Open Access Journals (Sweden)

Lindis Skipperud

2004-01-01

Full Text Available Anthropogenic plutonium has been introduced into the environment over the past 50 years as the result of the detonation of nuclear weapons and operational releases from the nuclear industry. In the Arctic environment, the main source of plutonium is from atmospheric weapons testing, which has resulted in a relatively uniform, underlying global distribution of plutonium. Previous studies of plutonium in the Kara Sea have shown that, at certain sites, other releases have given rise to enhanced local concentrations. Since different plutonium sources are characterised by distinctive plutonium-isotope ratios, evidence of a localised influence can be supported by clear perturbations in the plutonium-isotope ratio fingerprints as compared to the known ratio in global fallout. In Kara Sea sites, such perturbations have been observed as a result of underwater weapons tests at Chernaya Bay, dumped radioactive waste in Novaya Zemlya, and terrestrial runoff from the Ob and Yenisey Rivers. Measurement of the plutonium-isotope ratios offers both a means of identifying the origin of radionuclide contamination and the influence of the various nuclear installations on inputs to the Arctic, as well as a potential method for following the movement of water and sediment loads in the rivers.

The present Japan-China joint development project is intended to study liquefaction performance of different types of Chinese coals, select coal types suitable for coal liquefaction, and serve for enhancement in the coal liquefaction technologies employed by the Chinese side. Since a small continuous testing device has been installed in fiscal 1982 and begun with the trial operation in March 1983, the liquefaction test has been performed for about five years, and is scheduled to continue another three years. Chinese coals produced in seven provinces and two autonomous regions have been subjected to the coal type selection, on which discussions were given for liquefying reaction characteristics by using autoclave testing and small continuous testing devices. As a result, circulation tests were performed by the end of fiscal 1987 on five coal types, namely Beisu coal, Texgxian coal, Xianfeng coal, Shenmu coal, and Meihekou coal. Data were acquired during the circulation and at the equilibrium. Comparison of the results of tests on these five coal types with the results having been acquired from the 0.1-t/d BSU in Japan before modification verified the result being nearly reasonable.

How do rigid-lid assumption affect LES simulation results at high Reynolds flows?

Science.gov (United States)

Khosronejad, Ali; Farhadzadeh, Ali; SBU Collaboration

2017-11-01

This research is motivated by the work of Kara et al., JHE, 2015. They employed LES to model flow around a model of abutment at a Re number of 27,000. They showed that first-order turbulence characteristics obtained by rigid-lid (RL) assumption compares fairly well with those of level-set (LS) method. Concerning the second-order statistics, however, their simulation results showed a significant dependence on the method used to describe the free surface. This finding can have important implications for open channel flow modeling. The Reynolds number for typical open channel flows, however, could be much larger than that of Kara et al.'s test case. Herein, we replicate the reported study by augmenting the geometric and hydraulic scales to reach a Re number of one order of magnitude larger ( 200,000). The Virtual Flow Simulator (VFS-Geophysics) model in its LES mode is used to simulate the test case using both RL and LS methods. The computational results are validated using measured flow and free-surface data from our laboratory experiments. Our goal is to investigate the effects of RL assumption on both first-order and second order statistics at high Reynolds numbers that occur in natural waterways.

In this study, the effects of callus age, ultraviolet (UV) irradiation and incubation time were investigated for the induction of trans-resveratrol production in callus cultures of Kalecik karası (Clone 12) Vitis vinifera L. grape cultivar. Part of leaves (~1 cm 2 ) were taken from one year old grapevines grown in greenhouse and then were cultured in Gamborg B-5 media including 2% saccarose, 0.8% agar, 1.0 μM BAP (6-benzylaminopurine) and 0.1 μM 2, 4-D (2, 4-dichlorophenoxy-acetic acid). After the second subculture, 12 and 15 days old callus tissues were exposed to 254 nm UV light at 10 cm distance from the source for 10 and 15 min. Trans-resveratrol was measured at 0, 24, 48 and 72 hours of incubation by using High Pressure Liquid Chromatography (HPLC). Trans-resveratrol concentration of control callus ranged from 0.56 to 0.96 μg g fw -1 . The highest trans-resveratrol production was obtained from 12 and 15 days-old callus irradiated for 10 min. at the 48th hours of incubation (2.42 μg g fw -1 ). Considering the highest value of trans-resveratrol concentration in controls and experiments, it was determined that UV irraditation in Kalecik karası elicitated the trans-resveratrol production by 2.5 times.

The project aims to develop a biocatalyst-assisted synthesizing method for efficiently manufacturing sugar containing polymers and polylactic acids which generate less environmental impact. The ALP-901 derived from actinomycetes operates best with 5% water content, and remains free of hydrolytic effect even when the rate rises to 20%, and catalyzes transesterification only. The esterification activity of bioprase rose remarkably upon addition of water. A polymer with a molecular weight of scores of thousands was obtained in the polymerization of sugar ester monomers. A sugar undecylenate with a double bond at an end was successfully polymerized. The sugar containing polymer exhibited excellent biodegradability. In a reaction of butanediol and lactide, several types of lactic oligomers different in molecular weight were synthesized. The oligomers were caused to react with divinylcarboxylic acid in the presence of an enzyme, and a polymerizable lactic oligomer was obtained. Furthermore, in a reaction between glucose and lactide, several lactic oligomer derivatives were synthesized, different in molecular weight. In a reaction of the derivatives and divinylcarboxylic acid with an enzyme added thereto, a polymerizable lactic oligomer derivative was obtained, which was brought into polymerization in the presence of a radical polymerization initiator for the production of a high molecular weight gel.

This project is aimed at promotion of effective utilization of unutilized resources by transforming histidine-containing peptide (anserine), enzymatically hydrolyzed muscle protein present in lean salmon swimming off the Sanriku District in the spawning season, into functional peptide. A reactor system, comprising an enzyme-immobilized column and rotary bioreactor, is investigated to efficiently produce peptide by enzymatically hydrolyzing the water-insoluble muscle protein. Anserine is isolated by ethanol extraction, ion-exchanging and partition chromatography. The TPTZ and ABTS methods are developed for speeding up measurement of the antioxidant activity. The salmon muscle protein is hydrolyzed by 3 types of enzymes, to measure the free radical erasing activity by the ABTS method. The enzymatically hydrolyzed protein is fractionated by gel permeation chromatography. The fractions having a molecular weight of 10,000 or less show strong antioxidant activity. The hydrolyzed protein shows improved activity by the iron rhodanide method when it has histidine at the center of tripeptide, and strong radical erasing function when it has thyrosine or tryptophan at the carboxyl terminal.

This paper describes research achievements in fiscal 1979 in research on hydrogen fueled automobiles as a research on hydrogen energy subsystems. The previous fiscal year has researched heat insulation methods to reduce evaporation loss from a hydrogen tank, prototype liquid level meters, prototype feed pumps (especially material selection for sliding parts) and a flow rate control method. Fiscal 1979 performed measurements of temperatures in different parts in the tank to elucidate how the heat makes invasion. Measurements were performed for the pump on suction valve behavior, internal pump compression force, liner temperatures, and leakage amount. The status of operation was identified and a high performance pump for use in very low temperatures was developed successfully. The pump has high delivery pressure, good durability, and capability of fine adjustment in the delivery quantity. This made the direct injection system for hydrogen fuel possible. Injection of hydrogen into an engine was possible by vaporizing liquefied hydrogen and supplying it as a low temperature gas used at 0 to -40 degrees C. The system has high efficiency. Fuel feed control was possible at the same level as in the existing automobiles. The prototype direct injection system can handle stably the load in actual cars. Material for the fuel tank is an important problem in terms of weight, whose solution is urged. (NEDO)

A comparative study of the cost effectiveness in improvement of emission gas was made between the diesel particulate filter (DPF) which is studied as measures against toxic emission gas from the vehicles already sold and the compressed natural gas (CNG) vehicle which has a large number of spread among clean energy vehicles. In the trial calculation, 18 cases were set up using measures by year against diesel car emission gas, use period and annual running distance as valuables. As a result of the study, the following conclusions were obtained. At the present time, when the vehicle price dropped approximately 40% from that at the beginning of the introduction, the cost effectiveness of CNG vehicle is larger than that of diesel car with DPF. Since the unit price of natural gas is comparatively higher than that of light oil, the longer the annual running distance is, the smaller the cost effectiveness of CNG vehicle is than that of diesel car with DPF. The durability period of DPF is considered not so long, and therefore, the longer the use period is, the larger the cost effectiveness of CNG vehicle is than that of diesel car with DPF. (NEDO)

The paper reported on a Tokyo-Nagoya travel test on a practical spread type solar-electric vehicle, Solar-EV. A comparative study was made running the same type gasoline vehicle, GV. The measured power consumption amount of Solar-EV is 57.6 kWh. By converting it into Mcal unit, an energy consumption amount of 49.5 Mcal was obtained. Further, as to GV, the energy consumption amount of 316 Mcal was obtained using the amount of supply of gasoline (mean heating value: 8.4 Mcal/h) of 37.6 l and the fuel consumption of 16.2 km/l. Accordingly, the energy consumption amount of Solar-EV became a sixth of that of GV. In the cost comparison, the cost of Solar-EV was 1,440 yen (power source price: 25 yen/kWh), which is about a third of that of GV, 3760 yen (gasoline unit price: 100 yen/l). Monocrystal Si solar cells, 270W, installed on hood/roof are connected to the main 288V system (the auxiliary 12V system is amorphous Si), and generate power 4.4 kWh during travel. A total power consumption amount of Solar-EV in the total travel (Tokyo-Nagoya) is 79.9 kWh including the auxiliary system, approximately 6% of which was to be supplied from solar cells. 1 ref., 6 figs., 3 tabs.

1997-01-30

This paper describes a simulation for a case when an energy capacitor system (ECS) is mounted in a hybrid electric vehicle in place of secondary batteries. The ECS is electric power storage equipment consisted of capacitors and electronic circuits, and capable of quick charge and discharge at high efficiency. Its energy density per unit weight is about the same as lead-acid batteries, but its output density is greater than any type of batteries. Being free of deterioration due to charge and discharge, its cycle life is almost limitless. In order to suppress heat generation, a switching converter is used to control the output to about 300W. However, internal resistance of an ECS is smaller than in an equivalent secondary battery, and internal loss and heat generation stay as low as 1/5 to 1/10. Discussions have been given on cases of using the ECS in small passenger cars, small buses/trucks, and large buses. Since the ECS can use the stored power to about 94% of the capacity, and its cycle life is sufficiently long, it can operate with charge capacity as small as 1/4 of a lead-acid battery. The weight can also be reduced largely. Regenerative power storage efficiency is high, fuel consumption can be improved, heat generation is less, and no forced cooling is required. 9 refs., 4 figs., 1 tab.

Application of thermal spraying for automotive parts is described. Outlines of the spraying types that are materialized recently, like 'gel-double spraying of turbo-compressor housing part' and 'iron alloy spraying to outer portion of valve lifter made with Al alloy', are introduced. Gel-double spraying technology is widely used in the jet engine of aeroplane, however its use in automotive turbo was difficult from the reason like quality assurance relating to continuous production of automotives. As a result of the research and development based on the above reasons, a low speed torque is confirmed by the formation of gel-double spray layer. Spraying to the outer part of the valve lifter made from Al alloy is cited as the best example of thermal spraying. Relation between flying speed of spraying particles and degree of flattening, etc., relating to the conformity of adhesion power of coated layer, is explained. Further research topics are given as; improvement of spraying efficiency, improvement of resistance of spraying equipments, unification of equipments standards, quantification of spray coatings, design of spray materials, etc. 9 refs., 8 figs., 1 tab.

The special attention was given to the meiobenthic organisms - the small bottom animals inhabiting a small space between grains of the sediment. It is possible to conclude that meiobenthos reacts to the radioactive pollution by the change of the taxonomic diversity and quantitative characteristics faster then macrobenthos, which is more inert component, less subjected to the influence of this factor.

Full Text Available This is the first publication of a hitherto unknown acrostic by an avant-garde poet, I. A. Aksenov. The poem was found in the archive of the Russian Union of Soviet Writers (VSSP in the Manuscript Section of the Institute of World Literature (IWL. This poem dated 1918 is a complex example of Russian avant-garde poetry demonstrating subtle mechanisms of meaning-making. The essay places the poem within the context of Aksenov’s work and relates it to his biography (cf. his friendship with a poet, K.A. Bol’shakov, to whom the poem was dedicated and the participation of both in S.G.Kara-Murza’s literary circle “Tuesdays”. It outlines the basic structure of the acrostic, reveals its main linguistic devices and intertextual connections. The analysis shows that the acrostic was thematically connected with two poems Aksenov and Bol’shakov wrote later the same day at Kara-Murza’s house. All the three texts capture the incubus of the Civil war (more precisely, the so called «Red terror» in the Fall of 1918 but also express hope for the return of the normal life, relying on friendship of like-minded people. In addition to this, the essay reveals possible interrelation between poetic techniques of Bol’shakov and Aksenov; this will enable us to better understand the specificity of these two understudied representatives of Russian avant-garde.

An assumption is made, that mechanisms of physiological regenration of the investigation tissues in rodents of arid zones, located in different continents, differ in principle. Physiological regeneration in Rhombomys opimus and meriones unguiculatis inhabiting the Kara Kum desert and the Baikal region mainly occurs in the results of intracellular repair and in Dipodomus merriamy from Mexican Sonora desert - to a great extent by way of intensive cell division and replacement of cellular populations by other ones. The reason for the different detected lies most probably in different ways of evolution of these animals

Asian countries are now attracting attention of automobile manufacturers of the world for their capabilities of buying, producing, and assembling of automobiles, and producing and supplying of parts, which means that the Asian market is now exposed to globalization. As for the automobile and part manufacturers of Japan, in the presence of economic depression lingering in Asia affecting motorization and rapid changes in the circumstances Japan`s automobile industry finds itself under, are pressed to work out new strategies as a member of the Asian community. A panel discussion of the same name as the subject held in 1997 won favor as a fine initiative to suitably cope with the difficult situation. Useful suggestions and proposals were made concerning the panel discussion, calling the event a new type of round-table talks well responding to the rapid changes in the world economy since 1997, by learned and experienced people, the government offices concerned, staffers of manufacturers in charge of overseas marketing, and international information analysts. They related to the current state and tasks of automobile manufacturing in Asia, trends of regulations and standardization, rolls of technical assistance and the Society of Automotive Engineers of Japan, Ltd., expressed from a wide angle covering various problems relative to environmental protection, safety, etc. (NEDO)

When the oil resources situation is taken into consideration, it is important to prepare now for the demand and supply situation of oil in the 21st century. The first method of the preparation is the noble-use of oil. The second method is the development and popularization of energies for transportation equipment which can take the place of petroleum. The candidates are synthetic liquid fuel, natural gas, and electricity (secondary batter). Methanol is the only synthetic liquid fuel which has the possibility of competing with petroleum both technologically and economically. By using methanol, cleaner combustion can be expected as compared with petroleum and coal. Methanol can be produced via synthetic gas not only from coal but also from natural gas, oil sand, oil shale, and biomass. From the technological point of view, innovation of quantity production technology of methanol is the first important subject. The second importance is the development of methanol vehicles and methanol fuel. Presently, methanol vehicles and fuels are in the stage of wide range and long-term verification test by running actual vehicles. 1 tab.

This paper describes the result of discussions on hydrogen fueled automobiles in fiscal 1978. Hydrogen fueled automobiles have a difficulty in developing methods for transporting hydrogen, whereas the liquefied hydrogen method and the metal hydride method are being studied in parallel at the present. It is also necessary to solve such basic problems as the method for supplying hydrogen to engines, the injection method, and countermeasures for abnormal combustion. Safety assurance is also important. Very little information is available presently on methods for storing hydrogen inside a car and supplying thereof, which are required for evaluating utilization of liquefied hydrogen to automobiles. Demonstrative surveys and researches are required to acquire basic materials for hydrogen feeding methods in broader meaning including storage and control. Therefore, fiscal 1977 has begun trial fabrication of experimental liquefied hydrogen tanks, and preliminary and experimental researches on types and materials for feed pumps. Fiscal 1978 has moved forward improvements in prototype tank performance (heat insulation method to reduce evaporation loss), trial fabrication of liquid level meters, trial fabrication of feed pumps (especially selection of materials for the sliding parts), and researches on flow rate control methods. Drawings for modification and experiment of the liquefied hydrogen tanks were prepared, and the promising candidates were selected for material combination in pump sliding parts. Durability tests are continuing thereon. Flow rate control was also discussed. (NEDO)

Full Text Available An effective in vitro regeneration system is one of the prerequisites for genetic manipulation of alfalfa (Medicago sativa L. varieties and genotypes. In this research, somatic embryogenesis of four alfalfa genotypes, 6-18 (synthetic, 4-14 (Kara Yonje- Karakozlu, 3-27 (Kara Yonje Maraghe and y-6 (Regen-SY, were investigated using leaf and petiole explants. Formation of callus and somatic embryogenesis was significantly influenced by the explant type and interaction of genotype and culture medium. Petiole explants of genotype 4-14 produced the highest yield of callus (0.406 gr fresh weight of callus. Percentage of somatic embryogenesis and the number of embryos per callus in petiole explants of genotype 4-14 was higher than those of other genotypes and explants. In genotype 6-18, the highest percentage of somatic embryogenesis was achieved on MS medium containing 5 mg/L 2,4-D and 2 mg/L kinetin. There was no significant differences between genotypes and explants in terms of embryo conversion to plantlet, and on average, 58% of somatic embryos converted to plantlet on MS medium. The petiole explants of genotype 6-18 did not exhibit somatic embryogenesis response in medium containing low ratio of 2,4-D:Kinetin (5 mg/L 2,4-D and 2 mg/L kinetin. While, these explants showed somatic embryogenesis in higher ratio of 2,4-D:Kinetin (5:1. The plantlet conversion efficiency of somatic embryos produced through this study was relatively higher and therefore, the method presented in this study could be used in alfalfa genetic manipulation and molecular studies.

Storm surges and extreme waves are severe natural sea hazards. Due to the almost complete lack of natural observations of these phenomena in the Russian seas (Caspian, Black, Azov, Baltic, White, Barents, Okhotsk, Kara), especially about their formation, development and destruction, they have been studied using numerical simulation. To calculate the parameters of wind waves for the seas listed above, except the Barents Sea, the spectral model SWAN was applied. For the Barents and Kara seas we used WAVEWATCH III model. Formation and development of storm surges were studied using ADCIRC model. The input data for models - bottom topography, wind, atmospheric pressure and ice cover. In modeling of surges in the White and Barents seas tidal level fluctuations were used. They have been calculated from 16 harmonic constant obtained from global atlas tides FES2004. Wind, atmospheric pressure and ice cover was taken from the NCEP/NCAR reanalysis for the period from 1948 to 2010, and NCEP/CFSR reanalysis for the period from 1979 to 2015. In modeling we used both regular and unstructured grid. The wave climate of the Caspian, Black, Azov, Baltic and White seas was obtained. Also the extreme wave height possible once in 100 years has been calculated. The statistics of storm surges for the White, Barents and Azov Seas were evaluated. The contribution of wind and atmospheric pressure in the formation of surges was estimated. The technique of climatic forecast frequency of storm synoptic situations was developed and applied for every sea. The research was carried out with financial support of the RFBR (grant 16-08-00829).

Despite the history of the Semipalatinsk test site in nuclear weapons testing, this territory is of interest for geologic exploration and utilization of mineral resources. The prospect for minerals on this territory was already known before the beginning of tests. Nowadays several companies work on the territory. Positive experience of using Kara Zhira coal deposit, refinement of local gabbros and stone-cutting plant, and preparation of gold mining at Naimanzhal deposit, allow us to hope that these mineral and raw material resources of the Semipalatinsk test site can become an important economic factor for development of the Eastern Kazakhstan region.

This report summarizes the fiscal 1980 research result on preventive technology of scale deposition derived from hot water. Hot water of Nigori-Gawa, Hokkaido forms CaCO{sub 3} scale just after releasing into ambient air, and scale composed of amorphous silica and calcite at 60 degrees C or less, reaching a peak around pH 8. Deposition increases with a decrease in flow velocity and temperature. Polymerized silica removal experiment was made using Otake hot water and a floatation separator of 1 T/H. No cation and kerosene, and additional 6A-1 (coconut amine) and NS-18 (amine T) were effective for floatation separation. Continuous operation of the floatation separator of 50 T/H and a sludge recycling equipment was carried out as test for practical use. It was confirmed that addition of amine system floatation agent to hot water of 80 degrees C and pH 5 with polymerized silica of 20ppm is effective for reduction of polymerized silica in treatment water to 5ppm or less. The treated water was reinjected into Otake No.6 reinjection well. The sludge recycling equipment was tested for recycling floatation sludge separated, resulting in achievement of an expected target.

The R and D were conducted of saccharide polymer using biocatalyst and polylactic acid using biocatalyst. In the R and D of technology to synthesize polymerizing saccharide ester, the use of ALP901 led to success in acquiring hydrophobic polymerizing saccharide ester and saccharide ester with phenol residue. A study was also made of technology to synthesize polymerizing divinyl ester. In the study of the optimization of enzyme reaction conditions, the optimum temperature of ester exchange was 50 degrees C, and also under much higher temperature, 100 degrees C, the enzyme reaction was found to proceed with. In the study of the synthesis of polylactic acid, it was impossible to obtain polymer in the case of using ester lactate. However, in the case of using lactic acid, polymer was acquired at the numerical average molecular weight of approximately 1,200. In the study of the optimization of enzyme reaction conditions, polymer with high molecular weight was acquired at the enzyme amount of 5-10%. It was found out that the conversion rate exceeds 98% in the case of doing the reaction for more than 3 days at the enzyme amount of 5-10%. (NEDO)

Physically handicapped people due to accidents for example have been increasing yearly in number with the increase of the aged, spread of cars, and change in the living environment. Therefore, participation in society by such people as called the weak is indispensable. Under the circumstances, as a means of their participation, a wheel chair as a moving aid was examined from the viewpoint of medical treatment and classified into three categories as follows: (1) for the use of the aged who are healthy but leg muscles are weak, (2) for the use of the invalid incapable of moving a part of the body and (3) for the use in sports by people who are disabled in the lower half of the body but healthy otherwise. In other words, prototypes were made for three kinds of solar wheel chair, for the aged, for the invalid and for sport use by the disabled, with a field test performed for each prototype. The wheel chairs were exhibited in the school, used in welfare facilities and driven by a disabled person who participated in 100km marathon. The users` opinions were favorable stating they were able to drive by themselves the new vehicle utilizing the clean energy and to move around by their own free will. 6 refs., 5 figs.

Prissy’s Quittin’ Time: The Black Camp Aesthetics of Kara Walker

2017-12-01

Full Text Available Through a close reading of Walker’s first silhouette instalment-the audaciously titled Gone, An Historical Romance of a Civil War as it Occurred Between the Dusky Thighs of One Young Negress and Her Heart (1994-this article examines how Walker utilises black camp to undermine both white supremacist and restrictive black uplift discourse. To be sure, the article is not an attempt to conflate these two, for the former is powerfully worse than the latter. However, it is necessary to explore how both discourses reinforce essentialist articulations of blackness and also to examine how black camp is a provocative analytic for their simultaneous disruption. Camp is usually understood as a queer-derived cultural practice that inflates identity to expose the constructed nature of gender. However, this article shows that black articulations of camp inflate identity to demonstrate the fiction of race as well.

2001-01-01

Satellite passive-microwave data have been used to calculate sea ice extents over the period 1979-1999 for the north polar sea ice cover as a whole and for each of nine regions. Over this 21-year time period, the trend in yearly average ice extents for the ice cover as a whole is -32,900 +/- 6,100 sq km/yr (-2.7 +/- 0.5 %/decade), indicating a reduction in sea ice coverage that has decelerated from the earlier reported value of -34,000 +/- 8,300 sq km/yr (-2.8 +/- 0.7 %/decade) for the period 1979-1996. Regionally, the reductions are greatest in the Arctic Ocean, the Kara and Barents Seas, and the Seas of Okhotsk and Japan, whereas seasonally, the reductions are greatest in summer, for which season the 1979-1999 trend in ice extents is -41,600 +/- 12,900 sq km/ yr (-4.9 +/- 1.5 %/decade). On a monthly basis, the reductions are greatest in July and September for the north polar ice cover as a whole, in September for the Arctic Ocean, in June and July for the Kara and Barents Seas, and in April for the Seas of Okhotsk and Japan. Only two of the nine regions show overall ice extent increases, those being the Bering Sea and the Gulf of St. Lawrence.For neither of these two regions is the increase statistically significant, whereas the 1079 - 1999 ice extent decreases are statistically significant at the 99% confidence level for the north polar region as a whole, the Arctic Ocean, the Seas of Okhotsk and Japan, and Hudson Bay.

Assessment of the future radioactive environmental contamination threat by releases from the dumped submarine and ship reactors with spent nuclear fuel (SNF) is a project goal. The methodology of search and detection of traces of noble gases ( 85 Kr, 222 Rn) and 3 H (which leaking the first from the SNF) on them plume on a bottom in dumpsites of ship nuclear reactors is advanced. Investigation of releases from the dumped ship reactors with SNF of icebreaker enin in Kara Sea is launched (September 2003). Research has multi-plane character: experiments with SNF, creation of techniques and expeditions. Preliminary observation of current field and hydrological characteristics in zone of marked dumpsites on the shelf has been fulfilled. For an estimation of a gas fission products release (including Kr-85) from the irradiated fuel during the corrosion in conditions a near-bottom layer of the sea in Arctic the special installation has been created in the RRC 'Kurchatov Institute' hot laboratory. Then the following experiment (modeling the conditions a near-bottom layer of the sea in Arctic) was made: First, samples of irradiated VVER-1000 type reactor fuel (UO 2 ) are loaded into capsules filled with pure sea water or sea water with the silt sampled in Kara Sea. The fuel samples have been selected due to similarity of its burnup level (62 MWd/kg) and other parameters to the one of icebreaker 'Lenin' reactor, that had been buried (1965) in Kara sea. The average sample activity was about 1 GBq for 137 Cs. Second, the capsules and the vacuum system are pumped out and checked on tightness by the helium leak tester. Then capsules are filled with the artificial gas mixture without traces of 85 Kr. Temperature of capsules are maintained in a range 0;1 deg C. Each 1-2 month gas samples are taken from the capsules into the previously pumped out flask, then capsules are refilled by the gas mixture. The measurements of 85 Kr concentration in the samples are carried out on low

For the purpose of promoting the utilization of clean energy vehicles (CEV), survey was made on the assessment of the pollution by the CEVs introduced by now, subjects on the utilization, etc. As to the transport business use CEV running in the market, CNG vehicle is mostly used, and therefore, the gas emitted from them was tested. As a result, it was found out that CNG vehicle emits fewer NOx, PM and soot/smoke than diesel cars and contributes to improving the air pollution in large cities. However, it emits more CO2 than diesel car, and accordingly, it is necessary to reduce the fuel consumption. The practicality in the limited running distance is almost the same as that of diesel car, but it is desirable to improve startability, acceleration and gradability. Further, the occurrence of any troubles was pointed out in a third of the total numbers of CEV vehicle. Improvement in reliability is a must. CEV is higher in car cost than diesel car, and for the spread/promotion, it is necessary to prepare for assistance such as subsidy. Moreover, there are many requests for improvement in number, business hours, supply capacity, etc. of fuel supply station. (NEDO)

For the purpose of letting the general public widely know of clean energy vehicles (electric car, hybrid car, natural gas car and methanol car) and making more effective/more efficient spread of them, investigational study was made of the method to spread them and let people know them. For the spread, it is important to confirm the feedback of information from the persons for PR at the time of conducting PR activities. As to the method using TV, radio, newspaper, magazine, etc., the following are pointed out: only a few information can be appealed; there is a possibility of the information being buried in a lot of other information; it seems difficult to get timely response. For this project, town events and exhibition events were considered suitable, and the results of the effects/efficiencies expressed in the actual figures by carrying out 'Clean Energy Festa' were studied. As a result, comprehension of 'new energy' and 'clean energy vehicle' and changes in the attitude were confirmed through the questionnaire survey, etc. (NEDO)

The festa was implemented in Yokote (Akita prefecture), Nagoya, Osaka, Yokohama and Hiroshima. The details of each place were reported in terms of the following: outline of the implementation, map of the place and booths, opening ceremony, management at entrance, dome theater, place for enjoying/relaxing, festival plaza, parking lot, PR related works, etc. In Festa in Yokote, more people gathered than expected. The reasons seem to be: the festa was held in the existing amusement facilities; the show using costumes of popular characters and gifts of the lottery were effective. As to new energy and clean energy vehicles, appeal was made mainly by stamp rally and questionnaire survey. By moving people inside the place, it helped people to have an understanding of clean energy vehicles. Almost the same effects were recognized also in the other places. (NEDO)

This report summarizes the fiscal 1975 research results, and proposes the policy toward the future as follows. (1) Computational prediction on the future trend of hydrogen energy is active in the U.S.A. (2) For application of hydrogen derived from coal to transport, chemical synthesis of methane, methanol and gasoline from such hydrogen is in proposal because of difficult transport of LH{sub 2} or MH{sub 2}. (3) Complete run of Musashi Institute of Technology's LH{sub 2} passenger car in a long-distance rally, and trial run of Billings' MH{sub 2} minibus as challenge to practical use indicated new data, features and problems for hydrogen vehicles through experiences. (4) Conversion from a conventional soft-oriented attitude to a hard-oriented one is thus necessary. (5) Preparation of LH{sub 2} production facility is also necessary.

Survey was made with the aim of studying measures to be taken for introduction/promotion of clean energy vehicles (CEV) in the Kinki region and of making a guidebook which included 8 CEV introduction menus based on the characteristics/needs in the Kinki region. In the survey of the state of CEV introduction in the Kinki region, a total number of the CEVs introduced in the region was estimated at approximately 5,300 (19.1% of the whole country), which indicated that the CEV introduction was increasing in comparison with the rate of the general vehicles registered (14.6% of the whole country). On the other hand, the fuel supply stations prepared such as eco-station are limited mostly to Osaka prefecture, which showed that the base is still unprepared. From the questionnaire survey made for 367 autonomous bodies and main 73 companies, problems and the needs for the wide area/large quantity spread were grasped, and various basic data were obtained. To solve problems, the setting-up of the Kinki CEV introduction/spread/promotion committee (CEV Kansai) was studied. (NEDO)

This report summarizes the fiscal 1975 research results, and proposes the policy toward the future as follows. (1) Computational prediction on the future trend of hydrogen energy is active in the U.S.A. (2) For application of hydrogen derived from coal to transport, chemical synthesis of methane, methanol and gasoline from such hydrogen is in proposal because of difficult transport of LH{sub 2} or MH{sub 2}. (3) Complete run of Musashi Institute of Technology's LH{sub 2} passenger car in a long-distance rally, and trial run of Billings' MH{sub 2} minibus as challenge to practical use indicated new data, features and problems for hydrogen vehicles through experiences. (4) Conversion from a conventional soft-oriented attitude to a hard-oriented one is thus necessary. (5) Preparation of LH{sub 2} production facility is also necessary. (6) Stabilization of atomic hydrogen, expected various hydrides, and an H{sub 2}-O{sub 2}-water engine as new ideas are stimulating many researchers. (7) Study on gasoline cracking methods such as JPL is active. (8) Doubled cost of gasoline will probably promote practical use of hydrogen vehicles. (NEDO)

The details were outlined of the PR event 'Clean Energy Festa' which was carried out for PR activities for spread of new energy and clean energy vehicles. The festa was implemented in Yokote (Akita prefecture), Nagoya, Osaka, Yokohama and Hiroshima. The details of each place were reported in terms of the following: outline of the implementation, map of the place and booths, opening ceremony, management at entrance, dome theater, place for enjoying/relaxing, festival plaza, parking lot, PR related works, etc. In Festa in Yokote, more people gathered than expected. The reasons seem to be: the festa was held in the existing amusement facilities; the show using costumes of popular characters and gifts of the lottery were effective. As to new energy and clean energy vehicles, appeal was made mainly by stamp rally and questionnaire survey. By moving people inside the place, it helped people to have an understanding of clean energy vehicles. Almost the same effects were recognized also in the other places. (NEDO)

Several kind of three way catalysts with different metal compositions have been developed for trial and their N2O formation behaviors before and after the durability tests have been observed. Then by comparing the N2O formation behavior between new and durability tested catalysts, N2O increase mechanism with aging has been experimentally analyzed. As results, A catalyst temperature at peak N2O formation will sift to higher side by the aging and enters in the range that is the higher percentage in use during test cycle driving. Then this is the main cause of increase in total N2O emission. 4 refs., 10 figs., 2 tabs.

The Rapid Arctic Warming and Its Impact on East Asian Winter Weather in Recent Decade

Science.gov (United States)

Kim, S. J.; Kim, B. M.; Kim, J. H.

2015-12-01

The Arctic is warming much more rapidly than the lower latitudes. In contrast to the rapid Arctic warming, in winters of the recent decade, the cold-air outbreaks over East Asia occur more frequently and stronger than in 1990s. By accompanying the snow over East Asia, the strong cold surges have led to a severe socio-economic impact. Such severe cold surges in recent decade over east Asia is consistent with the more dominant negative phase of the Arctic Oscillation (AO), that may be attributed by the Arctic amplification. In both observation-based reanalysis and numerical model experiments, the Arctic sea ice melting leads to the weakening of the AO polarity by reducing the meridional temperature gradient through a heat flux feedback. The Arctic warming and associated sea ice melting over the Kara-Barents area in late fall and early winter first release a lot of heat to the atmosphere from the ocean by a strong contrast in temperature and moisture and higher height anomaly is developed over the Kara/Barents and the Ural mountains The anomalous anticyclonic anomaly over the Arctic strengthen the Siberian High and at the same time the east Asian trough is developed over the western coast of the North Pacific. Through the passage between the margin of the Siberian High and east Asian tough, an extremely cold air is transported from east Siberia to east Asia for sometimes more than a week. Such a severe sold air brings about the moisture from nearby ocean, largely influencing the daily lives and economy in north East China, Korea, and Japan. The recent Arctic and associated sea ice melting is not only contributed to the local climate and weather, but also a severe weather in mid-latitudes through a modulation in polar vortex.

Aerial gamma ray and magnetic survey: Powder River II Project, Gillette Quadrangle, Wyoming. Final report

International Nuclear Information System (INIS)

1979-04-01

The Gillette quadrangle in northeastern Wyoming and western South Dakota contains approximately equal portions of the Powder River Basin and the Black Hills Uplift. In these two structures, a relatively thick sequence of Paleozoic and Mesozoic strata represent nearly continuous deposition over the Precambrian basement complex. The Powder River Basin also contains a thick sequence of early Tertiary rocks which cover about 50% of the surface. A stratigraphic sequence from Upper Cretaceous to Precambrian is exposed in the Black Hills Uplift to the east. Magnetic data apparently illustrate the relative depth to the Precambrian crystalline rocks, but only weakly define the boundary between the Powder River Basin and the Black Hills Uplift. The positions of some small isolated Tertiary intrusive bodies in the Black Hills Uplift are relatively well expressed. The Gillette quadrangle has been productive in terms of uranium mining, but its current status is uncertain. The producing uranium deposits occur within the Lower Cretaceous Inyan Kara Group and the Jurassic Morrison Formation in the Black Hills Uplift. Other prospects occur within the Tertiary Wasatch and Fort Union Formations in the Pumpkin Buttes - Turnercrest district, where it extends into the quadrangle from the Newcastle quadrangle to the south. These four formations, all predominantly nonmarine, contain all known uranium deposits in the Gillette quadrangle. A total of 108 groups of sample responses in the uranium window constitute anomalies as defined in Volume I. The anomalies are most frequently found in the Inyan Kara-Morrison, Wasatch and Fort Union Formations. Many anomalies occur over known mines or prospects. Others may result from unmapped uranium mines or areas where material other than uranium is mined. The remainder may relate to natural geologic features

Pore Pressure and Field stress variation from Salt Water Injection; A case Study from Beaver Lodge Field in Williston Basin

One of the major concerns in producing from oil and gas reservoirs in North American Basins is the disposal of high salinity salt water. It is a misconception that Hydro frack triggers Earthquakes, but due to the high salinity and density of water being pumped to the formation that has pore space of the rock already filled, which is not the case in Hydro-frack or Enhanced Oil Recovery in which fracturing fluid is pumped into empty pore space of rocks in depleted reservoirs. A review on the Bakken history showed that the concerns related to induce seismicity has increased over time due to variations in Pore pressure and In-situ stress that have shown steep changes in the region over the time. In this study, we focused on Pore pressure and field Stress variations in lower Cretaceous Inyan Kara and Mississippian Devonian Bakken, Inyan Kara is the major source for class-II salt-water disposal in the basin. Salt-water disposal is the major cause for induced seismicity. A full field study was done on Beaver Lodge Field, which has many salt-water disposal wells Adjacent to Oil and Gas Wells. We analyzed formation properties, stresses, pore-pressure, and fracture gradient profile in the field and. The constructed Mechanical Earth Model (MEM) revealed changes in pore pressure and stresses over time due to saltwater injection. Well drilled in the past were compared to recently drilled wells, which showed much stress variations. Safe mud weight Window of wells near proximity of injection wells was examined which showed many cases of wellbore instabilities. Results of this study will have tremendous impact in studying environmental issues and the future drilling and Fracking operations.

Adaptive strategies and life history characteristics in a warming climate: salmon in the Arctic?

Science.gov (United States)

Nielsen, Jennifer L.; Ruggerone, Gregory T.; Zimmerman, Christian E.

In the warming Arctic, aquatic habitats are in flux and salmon are exploring their options. Adult Pacific salmon, including sockeye (Oncorhynchus nerka), coho (O. kisutch), Chinook (O. tshawytscha), pink (O. gorbuscha) and chum (O. keta) have been captured throughout the Arctic. Pink and chum salmon are the most common species found in the Arctic today. These species are less dependent on freshwater habitats as juveniles and grow quickly in marine habitats. Putative spawning populations are rare in the North American Arctic and limited to pink salmon in drainages north of Point Hope, Alaska, chum salmon spawning rivers draining to the northwestern Beaufort Sea, and small populations of chum and pink salmon in Canada’s Mackenzie River. Pacific salmon have colonized several large river basins draining to the Kara, Laptev and East Siberian seas in the Russian Arctic. These populations probably developed from hatchery supplementation efforts in the 1960’s. Hundreds of populations of Arctic Atlantic salmon (Salmo salar) are found in Russia, Norway and Finland. Atlantic salmon have extended their range eastward as far as the Kara Sea in central Russian. A small native population of Atlantic salmon is found in Canada’s Ungava Bay. The northern tip of Quebec seems to be an Atlantic salmon migration barrier for other North American stocks. Compatibility between life history requirements and ecological conditions are prerequisite for salmon colonizing Arctic habitats. Broad-scale predictive models of climate change in the Arctic give little information about feedback processes contributing to local conditions, especially in freshwater systems. This paper reviews the recent history of salmon in the Arctic and explores various patterns of climate change that may influence range expansions and future sustainability of salmon in Arctic habitats. A summary of the research needs that will allow informed expectation of further Arctic colonization by salmon is given.

Following a decline in 2014, spending on exploration is expected to drop by more than 20% in 2015, a clear shift from the consistently upward trend observed for over ten years, with the exception of a slight dip in 2009 and 2010. On the other hand, there is no expectation that the downward trend in volumes discovered will reverse itself, having fallen every year for the past five years despite a sharp rise in exploration budgets between 2010 and 2014. Notwithstanding, this overall decline in exploration performance worldwide has been accompanied by some spectacular successes, such as the two massive Pobeda discoveries in the Kara Sea in 2014, and the 2015 Zohr discovery in Egyptian offshore waters.

Data on the petrography, geochemistry, and isotopic geochronology of granites from the northern part of the Taimyr Peninsula are considered. The Early-Middle Carboniferous age of these rocks has been established (U-Pb, SIMS). Judging by the results of 40Ar/39Ar dating, the rocks underwent metamorphism in the Middle Permian. In geochemical and isotopic composition, the granitic rocks have much in common with evolved I-type granites. This makes it possible to specify a suprasubduction marginal continental formation setting. The existence of an active Carboniferous margin along the southern edge of the Kara Block (in presentday coordinates) corroborates the close relationship of the studied region with the continent of Baltia.

This report describes the vehicle autonomy by using artificial intelligence (AI) technology. Owing to a remarkable progress of AI technology, it is forecasted that driving support system will be introduced into the market till 2000, and higher autonomous navigation system will be introduced since about 2010. Autonomous vehicles have capacities of recognizing the outside world and of navigating roads by themselves, and with their enfanced environment adaptability the road transportation in the future is expected to be much more safer than in the present. The autonomous vehicle can warn its driver of potential dangers and correct operational errors of the driver. In order to realize such autonomous vehicles, extensive researches on perception systems, decision making systems and driving support systems are needed. 9 refs., 10 figs., 1 tab.

This paper introduces history of the development of an electric automobile, `Ecovehicle`. It is provided with a high overall energy efficiency compared with an engine vehicle. The Ecovihicle is 1.2m in width, 3.3m in length, 2 seating capacities and 910kg in overall weight with serially connected 56 batteries of each 4V, 40Ah and having the total weight of 269kg. Its travel distance per charging is 130km at a speed of 80 k.p.h. This vehicle is capable of running with an energy of approximately one third as much as that of a light car. In addition, the vehicle is provided with polycrystal solar batteries placed on 0.6m{sup 2} area on the roof and spoiler generating 60W maximum. Assuming the annual duration of sunshine is 1,800 hours, charging is possible for 63kWh annually. Assuming the charging efficiency is 83%, charging is possible about seven times, which is an equivalent of travelling about 1,000km annually. The characteristics for example are the employment of brushless DC motor, use of energy saving switching element IGBT in order to realize a low level of loss in the inverter, in-wheel motor system, and storage of storage batteries in a hollow aluminum frame installed under the floor. 2 refs., 5 figs., 1 tab.

Weight reduction of automobiles is required from the viewpoint of reduction of CO2 emission and energy conservation. Comparing a car with another one of almost the same size and performance with 1% reduced weight, combustion efficiency of the latter can be improved by 0.5-0.8%. This report introduces several examples, in which steel parts are replaced with light alloy parts to reduce car weight, and describes the future perspective. Concerning a cylinder block which is the heaviest part among engine parts, a block made of aluminum alloy with no cast liner has been developed. There is also an example of an oil pan adopting aluminum die-cast for a part of it. A valve lifter made of aluminum alloy has been developed for valve system parts and has contributed to friction loss, noise reduction, and improvement of fuel consumption. As for steering system parts, a steering bracket made of Mg alloy die-cast has been developed. The use of light alloy parts, in general, increases material cost. Therefore it is now required to build up closer connection between designs and production techniques and to improve reliability of casting and forging technologies. 5 refs., 20 figs.

Atlantic walrus (Odobenus rosmarus rosmarus): A literature survey and status report

Science.gov (United States)

Reeves, Randall R.

1978-01-01

It is generally agreed that the genus Odobenus includes only one species, O. rosmarus. At least two subspecies are widely recognized: O. r. rosmarus, the Atlantic walrus, and O. r. divergens, the Pacific walrus. A third nominal subspecies, O. r. laptevi, the Laptev walrus, is designated by some Soviet researchers; and the taxonomic status of the Kara Sea walrus is undetermined. The range and abundance of nearly all walrus stocks have been seriously reduced by intensive human exploitation.The Atlantic walrus, the principal subject of this study, remains plentiful in only three known areas of concentration: northern Hudson Bay and northern Foxe Basin in the eastern Canadian Arctic, and the Thule district of northwest Greenland. This animal is no longer the object of large-scale commercial hunting, but is still subject to heavy subsistence hunting by native groups in some areas.The status of the walrus population in Canada was investigated in the 1950's and is believed to have changed little since that time. There are probably no more than about 10,000 walruses in Canadian waters, virtually all of them in the eastern arctic. The biology, ecology, and exploitation of walruses in the Thule district were studied during the 1940's, and some information is available concerning recent catch levels and hunting practices. The Polar Eskimos of north Greenland continue to organize much of their cultural and economic life around the hunting of walruses, and the species remains abundant in their area, numbering at least a few thousand. The walrus stocks off west Greenland and in the Greenland, Barents, and Kara seas are the most critically depleted. No systematic field investigations of walruses east of Greenland have been made since the Kara Sea and Franz Josef Land populations were studied in the mid-1930's. Opportunistic sighting records and compilations of historical catch information indicate that the herds of many tens of thousands that once inhabited Svalbard, Bear Island

With international standardization as a target, research has been performed for three years since fiscal 1998 on a method for calculating the recycling rate of automotive products. This paper summarizes the achievements thereof. In fiscal 1998, studies were conducted on major automobile materials, state of recycling in Japan and Europe, and trial monitoring on recycling execution rate in the dismantling and shredding stages. Despite uncertainties that remain in recycling, the importance of standardization has been affirmed. Beginning in fiscal 1999, discussions have been given on requirements for establishing the recycling possibility by means of dismantling automobiles. In the requirements for establishing thermal recycling, discussions were given, taking into account the state of legal regulations in Germany and the trial execution of the container and packaging recycling law in Japan. As a result, the standard draft for the method for calculating the recycling rate was established for automotive products, including the method for calculating the recycling possibility rate, and the requirements for establishing thermal recycling. For international standardization of the method for calculating the recycling possibility rate, discussions have begun at ISO/TC22/WG10. (NEDO)

With proposal of a standard draft to ISO as a target, R and D has been performed for three years since fiscal 1998 on a method for measuring fuel consumption of hybrid electric automobiles. This paper summarizes the achievements thereof. In the R and D, analyses were conducted on elements particular to a hybrid system considered to influence the fuel consumption, such as the remaining capacity in the main batteries, fuel consumption for regenerative braking, and effects on exhaust gas. As a result, it was revealed that correction is required for change in the remaining capacity in the main batteries before and after the test with regard to the fuel consumption, and that this is possible. Discussions were given on a method for fuel consumption test by using the driving modes adopted in Japan, America and Europe using four types of HEV having different hybrid systems and mounted batteries. Comparisons and discussions were given on the 'continuously repeated mode averaging method','primary approximation method' and 'SAEJ1711 and its test establishment criteria'. As a result, the primary approximation method was proved to be the best as the HEV fuel consumption test method. At the same time, necessity of standardizing the current measuring device and the measuring method was pointed out in the fuel consumption measurement using the primary approximation method and SAEJ1711.

The Rapid City (1 0 x 2 0 ) Quadrangle, South Dakota, was evaluated for environments favorble for uranium deposits to a depth of 1500 m. Criteria used were those of the National Uranium Resource Evaluation. Field reconnaissance involved the use of hand-held scintillometers to investigate uranium occurrences reported in the literature and anomalies in aerial radiometric surveys, and geochemical samples of stream sediments and well waters. Gamma-ray logs were used to define the favorable environments in the subsurface. Environments favorable for sandstone-type uranium deposits occur in the Inyan Kara Group, the Fox Hills Sandstone, and the Hell Creek Formation. Environments considered unfavorable for uranium deposits include all Precambrian, Paleozoic, Mesozoic, and Tertiary rocks other than those identified as favorable

The 239,240 Pu concentrations measured in the sediment, macro algae and benthic fauna were very low in the Russian Arctic seas, and in fish, seabirds and seals usually below the detection limit. The 238 Pu/ 239,240 Pu ratios suggest that global fallout is the main source of the plutonium. Fallout level Pu isotope ratios, 0.02 - 0.04, were also found in surface vegetation and soil samples from fifteen locations covering Svalbard, Franz Joseph Land Archipelago, coastal areas and islands of the Barents, Pechora and White seas, including the southern coast of Novaya Zemlya, Kola Bay and the River Yenisey estuary. The areal 239,240 Pu concentrations of the terrestrial sampling plots varied from 9 to 32Bq/m 2 . Significantly enhanced 238 Pu/ 239,240 Pu ratios of 0.10 - 0.18 were detected only in the Kola Bay in sediment layers outside and to the south of the Atomflot civilian nuclear ice-breaker base. The enhanced isotope ratios in this section of the Kola Bay were verified by triplicate determinations. The highest ratios were found at a depth 6-7.5 cm, and not in the surface sediment layers, indicating a larger previous release. Plutonium is not concentrated in the marine foodchains. Accumulation of 239,240 Pu was detected in some species of benthic fauna; in molluscs mainly in the shells compared to the soft edible parts of the specimen. Plutonium was not detected higher in the marine food-chain. The 239,240 Pu concentrations measured in the bones and soft tissues of commercial fish species, sea birds and seals were below the detection limit. (author)

Full text: Great diversity of radio-ecological problems requires measurement of materials with vastly differing chemical composition and density, and varying volume. In case of gamma spectrometry such variation in composition, density and volume changes the response of a measuring system quite drastically. A necessary correction is usually achieved by applying one of the four correction methods. The first one is applying a standard with composition as close to the measured sample as possible. The second method needs some previous knowledge about the chemical composition of the sample and a subsequent calculation of the mass absorption coefficient. The third method, an intensity ratio of two gamma lines, can only be applied when an isotope in the investigated sample has two measurable gamma lines. The fourth method consists in an additional gamma transmission measurement, using an isotopic source. Application of the first two methods to samples collected in Kazakhstan is evaluated and the results achieved are described. Instrumental neutron activation analysis by either long, or short irradiation was applied to three groups of samples. The first 15 samples were from the Semipalatinsk area, the next 15 from the area north for the Kara-Tau range. The third group of 5 samples was from the Syr-Darya valley. The Kara-Tau and Syr-Darya samples originate from the area adjacent to an uranium mining site. Only two samples are collected at cultivated soil, all the other are collected at the steppe or semi-desert areas, In the additional group measured there were ten sub-samples of the environmental soil standard, prepared at the Institute of Nuclear Physics. Activation analysis was applied as well to Soil-6 and Soil IAEA-375, two reference materials distributed by IAEA. Determination of concentration of about 40 elements in very sample enabled computation of mass absorption coefficients for all the investigated samples.

The Marginal Ice Zone (MIZ) of the Arctic Ocean is changing rapidly due to a warming Arctic climate with commensurate reductions in sea ice extent and thickness. This Pan-Arctic review summarizes the main changes in the Arctic ocean-sea ice-atmosphere (OSA) interface, with implications for primary- and secondary producers in the ice and the underlying water column. Changes in the Arctic MIZ were interpreted for the period 1979-2010, based on best-fit regressions for each month. Trends of increasingly open water were statistically significant for each month, with quadratic fit for August-November, illustrating particularly strong seasonal feedbacks in sea-ice formation and decay. Geographic interpretations of physical and biological changes were based on comparison of regions with significant changes in sea ice: (1) The Pacific Sector of the Arctic Ocean including the Canada Basin and the Beaufort, Chukchi and East Siberian seas; (2) The Canadian Arctic Archipelago; (3) Baffin Bay and Hudson Bay; and (4) the Barents and Kara seas. Changes in ice conditions in the Barents sea/Kara sea region appear to be primarily forced by ocean heat fluxes during winter, whereas changes in the other sectors appear to be more summer-autumn related and primarily atmospherically forced. Effects of seasonal and regional changes in OSA-system with regard to increased open water were summarized for photosynthetically available radiation, nutrient delivery to the euphotic zone, primary production of ice algae and phytoplankton, ice-associated fauna and zooplankton, and gas exchange of CO2. Changes in the physical factors varied amongst regions, and showed direct effects on organisms linked to sea ice. Zooplankton species appear to be more flexible and likely able to adapt to variability in the onset of primary production. The major changes identified for the ice-associated ecosystem are with regard to production timing and abundance or biomass of ice flora and fauna, which are related to

Anthropogenic radionuclides in the Arctic Ocean. Distribution and pathways

Energy Technology Data Exchange (ETDEWEB)

Josefsson, Dan

1998-05-01

Anthropogenic radionuclide concentrations have been determined in seawater and sediment samples collected in 1991, 1994 and 1996 in the Eurasian Arctic shelf and interior. Global fallout, releases from European reprocessing plants and the Chernobyl accident are identified as the three main sources. From measurements in the Eurasian shelf seas it is concluded that the total input of {sup 134}Cs, {sup 137}Cs and {sup 90}Sr from these sources has been decreasing during the 1990`s, while {sup 129}I has increased. The main fraction of the reprocessing and Chernobyl activity found in Arctic Ocean surface layer is transported from the Barents Sea east along the Eurasian Arctic shelf seas to the Laptev Sea before entering the Nansen Basin. This inflow results in highest {sup 137}Cs, {sup 129}I and {sup 90}Sr concentrations in the Arctic Ocean surface layers, and continuously decreasing concentrations with depth. Chernobyl-derived {sup 137}Cs appeared in the central parts of the Arctic Ocean around 1991, and in the mid 1990`s the fraction to total {sup 137}Cs was approximately 30% in the entire Eurasian Arctic region. The transfer times for releases from Sellafield are estimated to be 5-7 years to the SE Barents Sea, 7-9 years to the Kara Sea, 10-11 years to the Laptev Sea and 12-14 years to the central Arctic Ocean. Global fallout is the primary source of plutonium with highest concentrations found in the Atlantic layer of the Arctic Ocean. When transported over the shallow shelf seas, particle reactive transuranic elements experience an intense scavenging. A rough estimate shows that approximately 75% of the plutonium entering the Kara and Laptev Seas are removed to the sediment. High seasonal riverine input of {sup 239}, {sup 240}Pu is observed near the mouths of the large Russian rivers. Sediment inventories show much higher concentrations on the shelf compared to the deep Arctic Ocean. This is primarily due to the low particle flux in the open ocean

Ringed seals from the south-western part of the Kara Sea (Dikson Island - Yenisei estuary) were the most contaminated with ΣDDTs, ΣPCBs, ΣCHL, and mirex as compared with those found in the other three areas of Russian Arctic, while the highest mean concentrations of ΣHCHs and PCDD/Fs were found in the blubber of ringed seals from the Chukchi Sea and the White Sea, respectively. Among all organochlorine compounds measured in ringed seals from the European part of the Russian Arctic, concentrations of ΣDDT and ΣPCBs only were higher as compared with the other Arctic regions. Levels of all other organochlorine compounds were similar or lower than in seals from Svalbard, Alaska, the Canadian Arctic and Greenland. ΣPBDEs were found in all ringed seal samples analysed. There were no significant differences between ΣPBDE concentrations found in the blubber of ringed seals from the three studied areas of the European part of the Russian Arctic, while PBDE contamination level in ringed seals from the Chukchi Sea was 30-50 times lower. ΣPBDE levels in the blubber of seals from the European part of the Russian Arctic are slightly higher than in ringed seals from the Canadian Arctic, Alaska, and western Greenland but lower compared to ringed seals from Svalbard and eastern Greenland.

The purpose of this verification survey is to confirm the performance and reliability with which a new large capacity capacitor works as power leveling use and partial power peak shift back-up use in the photovoltaic power system. The results of FY 1997 are as follows: (1) Verification using jelly-role type cells. (2) Trial manufacture of stacking cells. In (1), jelly-role type cells were manufactured using an electrode composed of aluminum foil and activated carbon layer and the organic electrolyte. The obtained cell capacitance was 6,000F on average and the energy density 5.4-5.6Wh/L. The experiment on the constant power load of a capacitor bank constructed with four 6,000F cells connected in series was carried out to confirm discharge energy of 25Wh between 12V and 3V. In (2), stacking rectangular type cells were trially manufactured by the electrode composed of two types of electrode; press type and sheet type electrodes. The cell capacitance was approximately 3,500F at sheet electrode cell, and the energy density 7.2Wh/L. To improve the cell performance, a relation was studied between the pore distribution of activated carbon and the double layer capacity, and the material higher than the conventional one in capacity per volume was found out. Studies were also made of trial fabrication of charge/discharge circuits and the experiment and the voltage balance. (NEDO)

For the purpose not only of solving the environmental problem but also of making effective use of resources and contributing to the appropriate treatment in the stage of the used resource, study was conducted of the standardization of a method to calculate recycle rates of automobile products. The FY 1999 results were summarized. In this fiscal year, to give definition of the recycle potentiality and thermal recycle, the following were proceeded with: trial evaluation of recycle potentiality, survey of the actual state of recycling of rubber/plastic parts, study of the requirements to realize the recycle potentiality, study of the requirements to realize the thermal recycle, and approaches to the international standardization. As to the trial evaluation of the recycle potentiality, tests to dismantle automobiles were made to assess the dismantlement, separation and recognition. The requirements to realize the recycle potentiality were studied. It was found out that few non-metallic materials are not recycled in the present situation. The paper studied what the requirements to realize the recycle potentiality and thermal recycle should be like basically since there is no recognition internationally unified. (NEDO)

For the purpose of proposing a measuring method of fuel consumption of hybrid electric vehicle (HEV) to ISO and internationally standardizing it, test/study were made. The FY 1999 results were summarized. In this fiscal year, the following were conducted using one new vehicle in addition to the two HEVs used in the previous fiscal year: assessment of generative energy at braking, and verification of the results obtained in FY 1998 such as changes in the remaining battery capacity before/after the test. Further, study was made on 'the concretely described contents of each element of the standards' and 'the method to correct changes in battery capacity and improvement in measuring accuracy.' Moreover, the items to be considered at the time of measuring current were made clear. Based on these studies, the making of a draft on the standards was finished. In addition, the measurement by overseas mode was also made, and it was confirmed that this is an effective measuring method also for overseas mode. In the investigational study, standards/papers overseas were surveyed. Exchanges of opinion on the technical background, etc. were also made with persons who are making the same studies overseas for mutual understanding. (NEDO)

The energy and environment issue was considered from a viewpoint of human happiness. The paper picks up economy, philosophy, energy and humans as organisms, and considered how the principle of the increase by geometrical progression plays an important role in these. That the repetition in phenomena is like the increase by geometrical progression means that changes increase not linearly but exponentially and nonlinearly and bring such large changes as are unimaginable. The increase in entropy, which is caused by a nonlinear increase of the state, is an irreparable change. The problem of the pursuit of happiness also cannot be solved by the linear thought. The energy and environment problem cannot reach the solution in an extension of the linear thought in which humans have overcome poverty and lacks since the past and pursued richness earnestly. Namely, it is necessary for the 21st century to stop thinking of the energy utilization for seeking for much more richness and to try to think the energy issue in the social system where happiness with not too much richness is presupposed. 16 refs., 1 fig., 1 tab.

The peculiar functions of the spaces with various sizes in the nature are revealed. Especially, in the ecosystem, the micro-spaces formed by the macromolecules such as enzyme, antibody, DNA and so on are the sources of the working of lives. In this paper, the development of the synthesis of polymers with necklace-shape starting with the discovery of the cyclodextrin forming polymers and complexes is introduced. It is shown by the obtaining of tube-shaped polymers with the polymer chain as the mold that the formation of super molecule is applicable to varied sorts of synthesis. Further, said molecular tube, which is different from carbon nanotube, is water soluble since it is from sugar and is possible to be conducted into an organism. Consequently, multifarious uses of said tube are considered such as the capsules of diverse pharmaceuticals or as the materials for the selective permeation in the separation of various ions and molecules. 7 refs., 3 figs.

Gazing the introduction target for fiscal 2000 and 2010, the paper arranged comprehensively and systematically the trend in Japan and overseas of clean energy cars and described subjects. Themes of the study to be promoted in terms of electric cars are: Li secondary batteries, heightening of performance of batteries such as Ni-hydrogen, power generation/power storage hybridization to make the long-distance travel possible. For the price reduction, the body is so made as to make it possible to select three kinds of power unit, that is, gasoline, hybrid, and electricity. Low noise and easy operation are also important. As to natural gas vehicles, the price is more than three times as high as that of gasoline vehicles, and relaxation of the related regulations on metal tanks, the Road Traffic Act, etc. is necessary. It is indispensable to establish quantity production and technical standards and reduce cost by the remodeling for bi-fueling with gasoline engines, development of FRP tanks, etc. Methanol vehicles are the closest to gasoline vehicles, but the introduction is delayed having no groups for generalization. Solar and hydrogen cars are promising, but are on a stage of developing the basic technology. 43 figs., 104 tabs.

“DARK SUN” IMAGE FROM NERVAL TO HİLMİ YAVUZ

Full Text Available “Dark Sun” image occurs in the various works of Gerard de Nerval. In his poem “El Desdichado”, on one hand it symbolizes the women he lost, on the other hand it refers to ‘Melancholia’ painting of Albrecht DURER. The same image scatters dark lights on forehead of DURER in Voyage en Orient (The voyage in Orient; and in Aurélia it is shown as a sign which announces the doomsday. Some comments have also been made that Nerval indicated his own tragic end with ‘dark sun’. When we take into consideration the poet’s life in a general approach, it is necessary to evaluate the image as a clear reflection of morbid psychic situation. Therefore, ‘dark sun’ image symbolizes unhappiness, uneasiness and melancholy primarily by Nerval and in Western culture. “Nur-u Siyah” (dark light image in orient culture has been employed in a line which continues from the tradition until today, from Şebüsteri to Şeyh Galip and from A. Halet Çelebi to Hilmi Yavuz. Althought they have the same meaning with a tiny difference (sun-divine light which arises from perception process, their imaginary figures in both civilizations are totally contrary to each other. So, “nur-u siyah” is the symbol of happiness, serenity, meanwhile, it is a symbol of the position which sufi has tried to reach with pantheism (Vahdet-i Vücud. In this article, it is tried to explain both civilizations’ usage of these images and then shifting to our era, to Hilmi YAVUZ, it will be tried to make an introduction to the using styles of “dark sun” and “nur -u siyah” or the other words which symbolizes them. “Kara Güneş” (le Soleil Noir imgesi Gerard de Nerval’in çeşitli eserlerinde geçer. “El Desdichado” şiirinde bir yandan kaybettiği kadınları simgelerken, diğer yandan da Albrecht Dürer’in “Melancholia” tablosuna göndermede bulunur.

A modeling experiment on the grounding of an ice shelf in the central Arctic Ocean during MIS 6

Jakobsson, M.; Siegert, M.; Paton, M.

2003-12-01

High-resolution chirp sonar subbottom profiles from the Lomonosov Ridge in the central Arctic Ocean, acquired from the Swedish icebreaker Oden in 1996, revealed large-scale erosion of the ridge crest down to depths of 1000 m below present sea level [Jakobsson, 1999]. Subsequent acoustic mapping during the SCICEX nuclear submarine expedition in 1999 showed glacial fluting at the deepest eroded areas and subparallel ice scours from 950 m water depth to the shallowest parts of the ridge crest [Polyak et al., 2001]. The directions of the mapped glaciogenic bed-forms and the redeposition of eroded material on the Amerasian side of the ridge indicate ice flow from the Barents-Kara Sea area. Core studies revealed that sediment drape the eroded areas from Marine Isotope Stage (MIS) 5.5 and, thus, it was proposed that the major erosional event took place during Marine Isotope Stage (MIS) 6 [Jakobsson et al., 2001]. Glacial geological evidence suggests strongly that the Late Saalian (MIS 6) ice sheet margin reached the shelf break of the Barents-Kara Sea [Svendsen et al. in press] and this gives us two possible ways to explain the ice erosional features on the Lomonosov Ridge. One is the grounding of a floating ice shelf and the other is the scouring from large deep tabular iceberg. Here we apply numerical ice sheet modeling to test the hypothesis that an ice shelf emanating from the Barents/Kara seas grounded across part of the Lomonsov Ridge and caused the extensive erosion down to a depth of around 1000 m below present sea level. A series of model experiments was undertaken in which the ice shelf mass balance (surface accumulation and basal melting) and ice shelf strain rates were adjusted. Grounding of the Lomonosov Ridge was not achieved when the ice shelf strain rate was 0.005 yr-1 (i.e. a free flowing ice shelf). However this model produced two interesting findings. First, with basal melt rates of up to 50 cm yr-1 an ice shelf grew from the St. Anna Trough ice stream

How might the North American ice sheet influence the northwestern Eurasian climate?

It is now widely acknowledged that past Northern Hemisphere ice sheets covering Canada and northern Europe at the Last Glacial Maximum (LGM) exerted a strong influence on climate by causing changes in atmospheric and oceanic circulations. In turn, these changes may have impacted the development of the ice sheets themselves through a combination of different feedback mechanisms. The present study is designed to investigate the potential impact of the North American ice sheet on the surface mass balance (SMB) of the Eurasian ice sheet driven by simulated changes in the past glacial atmospheric circulation. Using the LMDZ5 atmospheric circulation model, we carried out 12 experiments under constant LGM conditions for insolation, greenhouse gases and ocean. In these experiments, the Eurasian ice sheet is removed. The 12 experiments differ in the North American ice-sheet topography, ranging from a white and flat (present-day topography) ice sheet to a full-size LGM ice sheet. This experimental design allows the albedo and the topographic impacts of the North American ice sheet onto the climate to be disentangled. The results are compared to our baseline experiment where both the North American and the Eurasian ice sheets have been removed. In summer, the sole albedo effect of the American ice sheet modifies the pattern of planetary waves with respect to the no-ice-sheet case, resulting in a cooling of the northwestern Eurasian region. By contrast, the atmospheric circulation changes induced by the topography of the North American ice sheet lead to a strong decrease of this cooling. In winter, the Scandinavian and the Barents-Kara regions respond differently to the American ice-sheet albedo effect: in response to atmospheric circulation changes, Scandinavia becomes warmer and total precipitation is more abundant, whereas the Barents-Kara area becomes cooler with a decrease of convective processes, causing a decrease of total precipitation.

A field survey was conducted of oil shipment depots in Java and Bali islands owned by Indonesia's state-run oil company to study measures for reduction in greenhouse effect gas emissions. Studies were made on the grasp of the amount of the hydrocarbon vapor emitted into the air, the amount of the gasoline recovered in case of adopting the vapor emission preventive technology, equipment cost/operational cost, etc. Concretely, the following three were studied: change of the gasoline storage tank to the inner floating roof type, and prevention of evaporation loss at the time of receiving and breathing loss caused by temperature changes; replacement with the vapor recovery type loading arm to recover gasoline vapor generated at the time of shipment/filling, and installation of the vapor recovery unit to recover vapor as gasoline; vapor balance system to recover in underground tank the gasoline vapor generated at the time of filling gasoline at gas station. As a result of the study, the recovered gasoline amount was 66,393 Kl/y and the CO2 reduction amount was 14,474 t/y at oil shipment depots and approximately 650 gasoline stations in Jakarta and Surabaya.

Researches on preparation of membranes of various materials have been promoted by not systematic technique but separate techniques according to needs of concerned fields. To establish the efficient technique for membranes with pores of required uniform size according to needs of various industries, survey and study were made on process optimization and low-cost production method. Porous membrane is the leading candidate for new separation systems as separation medium in chemical industry, hot gas filtration for energy production and environmental purification engineering. The electrode, separator and gas storage medium of fuel cell vehicles and next-generation batteries require effective porous materials. The workshop on engineering porous materials held in May 1993 confirmed the time of following materials: High-efficiency gas separation membrane, chemical catalytic membrane, fuel cell electrode and absorbent for environmental purification. Development of inorganic membranes more excellent in high-temperature stability, strength, catalytic activity and corrosion resistance than previous polymer membranes is important. (NEDO)

The paper made an investigational study of the data of a wide range which seems to be related to the use of hydrogen as automobile use fuel. The advantage is that the exhaust can almost be non-pollutant. The engine performance can be on the same level as that of the present gasoline engine or can be improved. The reasons are that the compression rate is heightened and that automobile can be driven at lean mixture rate. As to weak points, the volume and weight increase when it is loaded on vehicle. The cost of hydrogen is higher than that of petroleum. The problems to be quickly solved are as follows. Improvement of the combustion method: a wide range of development not only the electric ignition method, but the diesel method, and the basic study for it. It is necessary to establish the basis for a method to connect the storage method and engine. It is also necessary to comprehensively review rules related to safety. For the future, the conversion to artificial fuel is indispensable, and hydrogen has the most characteristics as energy medium. The problem is much larger sizes of fuel tank and pump, but there will be a possibility of producing a new technology together with the hydrogen production technology. The fundamental research should be promoted without any hesitation. (translated by NEDO)

Discussions have been given on identification of actual status of exhaust gas emission during driving, starting, and idling of automobiles, on technologies to enhance fuel consumption and reduce exhaust gas emission, and on technologies to measure harmful substances. In the investigation of effects of environmental temperatures on evaporation gas, it was shown that fuel evaporation generated from the fuel tank increases as the average ambient temperature rises. In the investigation of effects of environmental temperatures on exhaust gas and fuel consumption, it was discovered that the effects of environmental temperatures on 10{center_dot}15 mode regulated exhaust gas differ depending on vehicles, and no definite difference due to combustion systems was recognized. Carbon monoxide and THC under the 11 mode regulation showed a trend to increase when the environmental temperature falls down. In the investigation of effects of fuel properties on exhaust gas, no definite difference due to combustion systems was recognized as a result of measurements using various types of gasoline having different distillation properties. In the investigation of analysis methods for harmful substances, development has been made on an analysis method mainly for 1-3 butadiene. (NEDO)

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

Sea Ice, Hydrocarbon Extraction, Rain-on-Snow and Tundra Reindeer Nomadism in Arctic Russia

It is assumed that retreating sea ice in the Eurasian Arctic will accelerate hydrocarbon development and associated tanker traffic along Russia's Northern Sea Route. However, oil and gas extraction along the Kara and Barents Sea coasts will likely keep developing rapidly regardless of whether the Northwest Eurasian climate continues to warm. Less certain are the real and potential linkages to regional biota and social-ecological systems. Reindeer nomadism continues to be a vitally important livelihood for indigenous tundra Nenets and their large herds of semi-domestic reindeer. Warming summer air temperatures over the NW Russian Arctic have been linked to increases in tundra productivity, longer growing seasons, and accelerated growth of tall deciduous shrubs. These temperature increases have, in turn, been linked to more frequent and sustained summer high-pressure systems over West Siberia, but not to sea ice retreat. At the same time, winters have been warming and rain-on-snow (ROS) events have become more frequent and intense, leading to record-breaking winter and spring mortality of reindeer. What is driving this increase in ROS frequency and intensity is not clear. Recent modelling and simulation have found statistically significant near-surface atmospheric warming and precipitation increases during autumn and winter over Arctic coastal lands in proximity to regions of sea-ice loss. During the winter of 2013-14 an extensive and lasting ROS event led to the starvation of 61,000 reindeer out of a population of ca. 300,000 animals on Yamal Peninsula, West Siberia. Historically, this is the region's largest recorded mortality episode. More than a year later, participatory fieldwork with nomadic herders during spring-summer 2015 revealed that the ecological and socio-economic impacts from this extreme event will unfold for years to come. There is an urgent need to understand whether and how ongoing Barents and Kara Sea ice retreat may affect the region's ancient

Assessing the risks of nuclear and chemical contamination in the former Soviet Union

International Nuclear Information System (INIS)

Kirk, J.

1996-01-01

In the first four chapters the focus is on risk assessment and the role of various segments of the society in defining risk criteria. In Chapter 2, the interface between science, policymaking, and environmental law is addressed. In chapter 3, the importance of including organizational and human factors in risk assessments is discussed. It is noted that risk assessment is also a matter for an informed public. Chapter 4 focuses on the specific application of technology to hazardous waste disposal. The most expensive high-tech equipment may not always be the best to solve a particular disposal problem. In Chapter 5 international efforts to determine the effects of nuclear testing are examined, moving on to question the methods used to define risk criteria. The last four chapters of the book focus on risk assessment and the role of various segments of the society in defining risk criteria. Chapter 6 is an introduction to the work done to assess the environmental and health affects of the 1986 accident at Chernobyl. Also the Ukrainian government's effort to assess additional natural and anthropogenic sources of radioactive contamination is discussed. In chapter 7, the efforts by the International Atomic Energy Agency and other organizations to assess the effects of Chernobyl are examined. The eighth chapter introduces the means by which nongovernmental environmental groups (NGO), e.g. Greenpeace, collect information on environmental threats and the role they play in informing the larger public about them. In this case, the dumping of radioactive waste in the Kara and Barents Seas is examined in detail. In Chapter 9 it is examined how interdisciplinary groups are required to assess the environmental and health effects of the dumping in the Kara and Barents Seas. The issues of reliable data and determining risk in the absence of data are discussed. In the final chapter, the major themes and results of the workshop are summarized, including a set of recommendations for

Authentic interpretations of Return of the Lands Act (1839

Directory of Open Access Journals (Sweden)

Stanković Uroš

2011-01-01

Full Text Available The article sheds light on three interpretations of Return of the Lands Act, introduced in 1839 and entitling landowners whose land was usurped by prince Miloš Obrenović (1815-1839, 1858-1860 and distinguished people's headmen to claim retrial of litigations over land adjudicated unjustly and return of their lawlessly disposed property. Two main questions arose in relation with interpretive rules - what were legislative power's goals when interpreting the Act and to what they were due. The author seeked the answer to the first dilemma by scrutinizing texts of interpretations, in order to determine their semantic meaning. In an attempt to provide the explanation for the second problem, he explored social context preceeding introduction of interpretive rules (namely, number of litigations before courts and political ambiance in Serbia. The first interpretation, dating back to March, 2nd 1843, is inclined towards previous owners of the land. Such solution was caused mainly by the political situation - Russia contested Aleksandar Karađorđević's first election for prince of Serbia in 1842 and the assembly foreseen to elect ruler anew was to be summoned in June 1843 In the meantime, new regime embodied in so-called constitution-defenders (the group of distinguished political leaders opposed to Obrenović dynasty struggled to ensure enthronement of its candidate and therefore issued a demagogic interpretation. On the contrary, two remaining interpretations, from the years 1844 and 1845, were aimed to retain status quo regarding land property by diminishing possibilities for new trial. The legislators opted for restrictions having learned that number of litigations had increased greatly. Besides, political climate was to the most extent convenient for taking such measures, as several lesser rebellions incited by the followers of Obrenović dynasty had been quelled easily, after which the opponents of the regime remained passive for a longer period

A basic experiment was carried out on a supplementary power supply, in which solar cells and electric double layer capacitors(EDLC) were combined for a DC/DC converter, for the use of a solar-electric vehicle (S-EV); and in actuality, an S-EV was loaded with the power supply with a running test conducted on a public road. The EDLC was found effective and useful for avoiding temporary lowering of voltage and momentary break. An electric supply was thereby made possible for an emergency light without the use of the DC/DC converter. However, in a tunnel or a night driving and in case of failure of the DC/DC converter, an operating time of only 7 minutes or so was affordable with the EDLC having a capacity of 100F. Moreover, particularly with a heavy load, it was impossible to maintain a voltage for many hours. Under the circumstances, an S-EV design would primarily require two sets of independent DC/DC converter loaded in the future. The EDLC, young after it was developed, still has a small energy density compared with a lead storage battery. Yet, an EDLC with a higher performance being developed, there is a possibility that it will be applied to S-EV`s by utilizing its characteristics such as a high efficiency and a long service life. 4 refs., 8 figs.

Water-soluble cutting fluids are able to be used for several months to several years if the proper periodical management is carried out. However, the used solution should be treated as waste water when the function-recovery thereof becomes remarkable difficult. On this occasion, the treated solution (drainage) ought to meet the environmental standards prescribed for the purpose of protecting globe environment. Many cases in Japan are that the strict rules are set by each urban and rural prefectures addition to the government ordinance. For carrying out the treatment of waste water efficiently, it is necessary to construct the treating system by mastering the characteristics of waste water and selecting the most suitable one from numerous treating methods. In this paper, after the description on the water-polluting substances and drainage standards, the general treating method of waste water miscible cutting fluids is described. Finally, the concrete cases with respect to the treatment of waste water treatment in automobile manufacturing factories are introduced. 5 refs., 5 figs., 5 tabs.

International Nuclear Information System (INIS)

Sazykina, T.G.

1995-01-01

A dynamic model is developed to assess the radioecological consequences of the radioactive waste dumping in the Arctic Ocean, with a special focus on the impact on fisheries. The contamination of important commercial species of Arctic fish is modelled with consideration for their living and feeding habits. Model predictions are made for biologically significant and long-lived radionuclides, such as 137 Cs and 90 Sr. The potential consequences of the dumping for Russian and Norwegian fisheries are analyzed, based on the statistical data for commercial fishery in the Arctic Ocean. Doses to humans due to the consumption of contaminated marine foodstuffs from the Arctic Ocean are estimated

The contribution of anthropogenic radionuclides from the European sources to the arctic seas have decreased in the first half of the 1990's. This is reflected in the measured activities in the different arctic seas which all show lower concentrations compared to earlier measurements. The influence from the Chernobyl accident were about one third of the total surface activity of {sup 137}CS at the Eurasian continental shelf in 1994 and between 10-30% in the central Arctic Ocean in 1996. The obtained results give no indication of any large extra sources for anthropogenic activity besides the well known fallout from atmospheric nuclear bombs test, discharges from European reprocessing plants and the Chernobyl accident releases. However smaller or local contributions from e.g. the dumped nuclear material in the Kara Sea and releases by the Siberian river from Russian nuclear facilities are not possible to exclude in this investigation.

Summer concentrations of C{sub 2}-C{sub 6} non-methane hydrocarbons (NMHCs) were measured in Antarctica and in the Arctic in 2008. The results show that NMHC concentrations are on average five times higher in the Arctic than in Antarctica. In Antarctica, there were few concentration peaks, but during most of the remaining time concentrations were below or close to the detection limits. Over the Arctic pack ice area north of 80 deg, concentrations of most of the measured NMHCs were always above the detection limits. No differences based on air-mass origin were detected in Antarctica, but samples collected over the central Arctic Ocean showed higher concentrations in air masses being advected from the Kara Sea and the western-central Arctic Ocean. The relatively higher NMHC-to-ethyne molar ratios calculated for samples collected over the central Arctic Ocean suggest additional alkane sources in the region. (orig.)

Sulphate rocks as an arena for karst development

Directory of Open Access Journals (Sweden)

Andrejchuk V.

1996-01-01

Full Text Available The rocks in which karst systems develop are most commonly composed of carbonate sulphate and chloride minerals. The sulphate minerals are quite numerous, but only gypsum and anhydrite form extensive masses in sedimentary sequences. Other minerals, which represent sulphates of K, Mg and Na, normally occur as minor beds (0.1-5.0 m, or as inclusions associated with chloride rocks. However some minerals precipitated in salt-generating basins, such as mirabilite and glauberite (typically formed in the Kara-Bogaz-Gol Gulf, salt lakes of Siberia and in China, form sequences up to 5-10 m thick where karst may develop. Due to the very high solubility of Na -sulphates, karst processes and features occurring in these rocks resemble salt karst. Thus, the term sulphate karst, although not strictly correct, is used mainly to indicate karst developed in gypsum and anhydrite.

Pan-Arctic Distribution of Bioavailable Dissolved Organic Matter and Linkages With Productivity in Ocean Margins

Rapid environmental changes in the Arctic Ocean affect plankton productivity and the bioavailability of dissolved organic matter (DOM) that supports microbial food webs. We report concentrations of dissolved organic carbon (DOC) and yields of amino acids (indicators of labile DOM) in surface waters across major Arctic margins. Concentrations of DOC and bioavailability of DOM showed large pan-Arctic variability that corresponded to varying hydrological conditions and ecosystem productivity, respectively. Widespread hot spots of labile DOM were observed over productive inflow shelves (Chukchi and Barents Seas), in contrast to oligotrophic interior margins (Kara, Laptev, East Siberian, and Beaufort Seas). Amino acid yields in outflow gateways (Canadian Archipelago and Baffin Bay) indicated the prevalence of semilabile DOM in sea ice covered regions and sporadic production of labile DOM in ice-free waters. Comparing these observations with surface circulation patterns indicated varying shelf subsidies of bioavailable DOM to Arctic deep basins.

This report describes a preliminary radiological assessment of collective doses to the world population from radioactive material dumped in the Barents and Kara Seas in the period 1961-1991. Information on the dumped waste and the rates of release of radionuclides have been available from Russian sources and from the International Atomic Energy Agency. A box model has been used to simulate the dispersion of radionuclides in the marine environment and to calculate the contamination of seafood and the subsequent radiation doses to man. Two release scenarios have been adopted. The worst-case release scenario which ignores the presence of barriers between spent nuclear fuel and seawater is estimated to give rise to about 10 mansieverts calculated to 1000 years from the time of release. A more realistic release scenario is estimated to cause about 3 mansieverts. In both cases exposure from the radionuclide {sup 137}Cs is found to dominate the doses. (au) 8 tabs., 56 ills., 19 refs.

The Hot Springs Quadrangle, South Dakota and Nebraska, was evaluated to a depth of 1500 m to identify environments and delineate areas favorable for the occurrence of uranium deposits. The evaluation used criteria developed by the National Uranium Resource Evaluation program. Surface reconnaissance was conducted using a portable scintillometer and a gamma spectrometer. Geochemical sampling was carried out in all geologic environments accessible within the quadrangle. Additional investigations included the followup of aerial radiometric and hydrogeochemical anomalies and a subsurface study. Environments favorable for sandstone-type deposits occur in the Inyan Kara Group and Chadron Member of the White River Group. Environments favorable for marine black-shale deposits occur in the Hayden Member of the Minnelusa Formation. A small area of the Harney Peak Granite is favorable for authigenic deposits. Environments considered unfavorable for uranium deposits are the Precambrian granitic and metasedimentary rocks and Paleozoic, Mesozoic, and Tertiary sedimentary rocks other than those previously mentioned

Leon Vintro, L.; McMahon, C.A.; Mitchell, P.I.; Josefsson, D.; Holm, E.; Roos, P.

2002-01-01

New data on the levels and long-range transport of plutonium in the Arctic Ocean, recorded in the course of two expeditions to this zone in 1994 and 1996, are discussed in this paper. Specifically, approximately 100 plutonium measurements in surface and sub-surface water sampled at 58 separate stations throughout the Kara, Laptev and East Siberian Seas, as well as along latitudinal transects across the Lomonosov Ridge, are reported and interpreted in terms of the circulation pathways responsible for the transport of this element from the North Atlantic to the Arctic Shelf and into the Arctic interior. In addition, the behaviour of plutonium in its transit through the vast Arctic shelf seas to open waters under extreme environmental conditions is discussed in terms of the partitioning of plutonium between filtered (<0.45 μm) seawater and suspended particulate, and its association with colloidal matter. Finally, limited evidence of the presence of a colloidal plutonium component in Arctic waters subject to direct riverine input is adduced

1995-01-01

Since the first demonstration by accelerator mass spectrometry for the measurement of 129 I in oceanic systems, the use of 129 I as a long range tracer has become widespread because the constraint of large sample volumes has been removed. Following extensive measurements of 129 I in both the Barents and Kara Seas, seawater samples were collected within the Canadian Arctic Basin, and at a cruise from the Chuchi Sea, across the pole, to the Norwegian Sea. Only 450 ml samples were required for all AMS measurements of Arctic seawater. Enhanced concentrations of 129 I were observed. Based on 137 Cs measurements for the same samples, the 129 I/ 137 Cs ratios showed the signature of Sellafield reprocessing effluents as the primary source of this 129 I. Based on average estimates, 13% of the total Sellafield/La Hague 129 I emissions now resides within the Atlantic layer of the Arctic Ocean. 7 refs., 3 figs

December through February 2015-2016 defines the warmest winter season over the Arctic in the observational record. Positive 2m temperature anomalies were focused over regions of reduced sea ice cover in the Kara and Barents Seas and southwestern Alaska. A third region is found over the ice-covered central Arctic Ocean. The period is marked by a strong synoptic pattern which produced melting temperatures in close proximity to the North Pole in late December and anomalous high pressure near the Taymyr Peninsula. Atmospheric teleconnections from the Atlantic contributed to warming over Eurasian high-latitude land surfaces, and El Niño-related teleconnections explain warming over southwestern Alaska and British Columbia, while warm anomalies over the central Arctic are associated with physical processes including the presence of enhanced atmospheric water vapor and an increased downwelling longwave radiative flux. Preconditioning of sea ice conditions by warm temperatures affected the ensuing spring extent.

Between 1978 and 1991 reactor-related solid radioactive waste was dumped by the former Soviet Union as unenclosed objects in the Pacific Ocean, east coast of Kamchatka, and the Sea of Japan. This paper presented estimates for the current (1994) inventory of activation and corrosion products contained in the reactor-related unenclosed solid objects. In addition, simple models derived for prediction of radionuclide release from marine reactors dumped in the Kara Sea are applied to certain of the dumped objects to provide estimates of radionuclide release to the Pacific Ocean, east coast of Kamchatka, and Sea of Japan environments. For the Pacific Ocean, east coast of Kamchatka, total release rates start below 0.01 GBq yr -1 and over 1,000 years, fall to 100 Bq yr -1 . In the Sea of Japan, the total release rate starts just above 1 GBq yr - 1 , dropping off to a level less than 0.1 GBq yr -1 , extending past the year 4,000

Investing in CIS: obstacles and strategies

International Nuclear Information System (INIS)

Anon.

1996-01-01

The CIS (Community of Independent States) needs the help of foreign investments to develop its huge hydrocarbon potentialities. Because of the uncertainties concerning the legal and fiscal context of their activities, the role of the international oil companies has remained limited so far. These problems were discussed in May 1996 during an important ''General Session'' of the OTC 96 congress. Proven and explored onshore oil reserves in Russia are enormous, in particular in Western and Eastern Siberia. However, the economically most interesting resources are located in the offshore zones of the Barents, Pechora and Kara seas and of Eastern Siberia and Okhotsk. This paper describes the last years decay of oil production in CIS and its causes, in particular the obstacles to foreign investments (exportation and transport taxes), the recent contracts and joint-ventures with American major companies (Exxon, Amoco..), and the situation of the Russian industry in petroleum engineering and field exploitation materials.

Unquestionably, the hierarchy concerns exclusively thesuperimposed reality. From the point of view of the vidyā all the levels of the phenomenal existenceare no longer valid. The cognition of the ultimate reality is called ‘sublation’ by Deutschand ‘contradiction’ by Hacker. The present article includes a suggestion of a new, presumablymore adequate term – ‘the annihilating cognition’, since the cognition of the ultimate realityinevitably involves the certainty of the non existence and the illusory nature of the phenomenalworld.

This report describes a preliminary radiological assessment of collective doses to the world population from radioactive material dumped in the Barents and Kara Seas in the period 1961-1991. Information on the dumped waste and the rates of release of radionuclides have been available from Russian sources and from the International Atomic Energy Agency. A box model has been used to simulate the dispersion of radionuclides in the marine environment and to calculate the contamination of seafood and the subsequent radiation doses to man. Two release scenarios have been adopted. The worst-case release scenario which ignores the presence of barriers between spent nuclear fuel and seawater is estimated to give rise to about 10 mansieverts calculated to 1000 years from the time of release. A more realistic release scenario is estimated to cause about 3 mansieverts. In both cases exposure from the radionuclide 137 Cs is found to dominate the doses. (au) 8 tabs., 56 ills., 19 refs

Agarwood, one of the timber woody plant which has the similar response as grand fir toward external invasion and is able to produce oleoresin as the secondary metabolite from plant defense system to inhibit the invader and heal the wound. Species of agarwood found in Malaysia is known as Aquilaria malaccensis, and locally known as karas or depu. A. malaccensis is valuable due to its oleoresin (gaharu). Gaharu is a product produced in the secondary metabolic pathway known as terpenoid synthesis pathway. In order to switch on this pathway, the plant defense system need to be induced and lead to the octadecanoid pathway where the linolenic acid (LA) converts to jasmonic acid (JA). Jasmonic acid is the major key to switch the plant metabolic pathway from primary metabolic pathway to secondary metabolic pathway. To prove this hypothesis, some researches on molecular study such as gene expression and protein expression are conducted to identify key components, which will lead to the manipulation of the metabolic pathway.

Continental runoff is a major source of freshwater, nutrients and terrigenous material to the Arctic Ocean. As such, it influences water column stratification, light attenuation, surface heating, gas exchange, biological productivity and carbon sequestration. Increasing river discharge and thawing permafrost suggest that the impacts of continental runoff on these processes are changing. Here, a new optical proxy was developed and implemented with remote sensing to determine the first pan-Arctic distribution of terrigenous dissolved organic matter (tDOM) and continental runoff in the surface Arctic Ocean. Retrospective analyses revealed connections between the routing of North American runoff and the recent freshening of the Canada Basin, and indicated a correspondence between climate-driven changes in river discharge and tDOM inventories in the Kara Sea. By facilitating the real-time, synoptic monitoring of tDOM and freshwater runoff in surface polar waters, this novel approach will help understand the manifestations of climate change in this remote region.

For the purpose of clarifying measures for reducing fuel consumption and exhaust gas of automobiles, survey was made of effects of environmental temperatures and fuel properties on exhaust gas. In the survey of effects of environmental temperatures, experiment on exhaust gas was carried out by changing the laboratory temperature from 5 degrees C to 35 degrees C using direct injection gasoline engine. As a result, it was found out that environmental temperatures have effects exhaust gas according to changes in purification rate by rise in catalytic temperature, changes in air/fuel ratio by changes in air density, control methods to secure starting-up/drivability, etc. In the survey of effects of gasoline properties, study was made on effects of distillation properties, especially, 90% distillation temperature (T90) on exhaust gas. As a result, in 10(center dot)15 mode, CO and THC decreased with a decrease in T90 both in three-way catalytic car and direct injection car. Especially, CO decreased to about 1/4 when decreasing T90 from 151 degrees C to 116 degrees C. NOx increased in three-way catalytic car and decreased in direct injection car with a decrease in T90.

Research and development was carried out for the application of aluminum foam manufactured by power metallurgy to automotive parts and components. Studies involved its application to the hood and bumpers of the passenger car for a great reduction in body weight and to the motor truck FUPD (front under protection device) making use of its high energy absorption capability. Specimens were manufactured of rods for evaluating the basic characteristics of the material, blocks for testing deformation characteristics, panels for evaluating acoustic characteristics, and large blocks for use in real vehicle collision tests. The material was tested for energy absorption using natural-size FUPDs. Aluminum foam is characterized in that its density is as low as 0.4-0.8g/cm{sup 3}, that under compression it produces a stress which stays almost constant until distortion reaches 40-60%, that it is excellent in absorbing energy, and so on. In a real-vehicle collision test, the material was found to be effective in buffering though the FUPDs absorbed less energy than expected. (NEDO)

For the purpose of spreading the technology for automobile maintenance in Saudi Arabia, an investigational study was made of the actual state of the automobile utilization environment in Saudi Arabia. In Saudi Arabia, air pollution is becoming a serious problem with the rapid progress of motorization, and measures for automobile maintenance technology should be taken such as the use of lead-free gasoline, spread of catalyst car and introduction of new engine technology. However, the number of able car mechanics with Saudi Arabian nationality is low, and they rely on workers from other countries for it. Further, usually people continuously drive cars at high speed under the severe environment where there are high temperature, solar radiation, dust, etc. As a result of the study, the following were cited as the maintenance technology of which the R and D are expected: technology for lead-free gasoline, basic education for electronics, technology for use of trouble diagnosis unit, technology of preventive maintenance supposing high speed traveling, technology for recycle use of parts, standards for maintenance of rubber parts, establishment of standards of maintenance of Saudi Arabia's own, making of technical books/data to be needed for training of Saudi Arabian engineers.

Full Text Available The location of this study is the border area of the North – West Bulgaria at Bulgarian – Serbian border, near the town of Belogradchik. As a result of several times redrawing of nation state borders between Serbia (Yugoslavia and Bulgaria during 20th century the borderland population, named Torlatsi had been separated. The Kada Boaz Fair creates a safe space and time for meeting of the separated families and friends, living at the both sides of the border. Very significant point is that the place of the Kada Boaz Fair is widely exploited of all local and governmental authorities from both sides since 2000 as a place to re-construct economic and social relations. The aim of the paper is to discuss which are the factors influencing the real openness and the making borders pervious. The paper explores the border crossing of Bulgarian and Serbian population, living at both sides of national borders on an everyday level, while trying to explain its notions in different periods of time (Socialist past, Yugo-embargo, EU accession of Bulgaria. The presentation answers the question how people use the political situations and politicians so that they could benefit from certain circumstances on their everyday level of life.

Power generation characteristics are investigated using data collected in photovoltaic power generation field tests being undertaken by NEDO (New Energy and Industrial Technology Development Organization). The photovoltaic power generation system performance is evaluated by examining loss factors leading to degradation in system performance, with weather conditions such as variation in insolation and air temperature, inverter performance, and shadows cast by surrounding buildings taken into consideration. As the result, it is found that the important loss factors are degradation in module performance due to elevated temperature, drift in the maximum output control, degraded inverter performance due to input power variation, effect of shadows, etc. It is learned that system is greatly affected by degradation in module performance due to increased temperature in summer and by shadows in winter, the two being responsible for the output coefficient dropping to approximately 75% throughout the year. The output coefficient frequency distribution charts for the 75 test sites confirm that the rate is as low as 70-80% at many sites. As for the system operating time, it tends to be longer in West Japan where the annual insolation rate is higher. 3 refs., 10 figs.

Discussions were given on properties of soap prepared from waste edible oil. A fresh oil, and soybean and rapeseed oils with different thermal oxidation degrees were used to prepare soap. On the other hand soap was made using wast edible oil after used at home. Soap made from fresh oil and thermally oxidized oil under a 3-hour heating at 90[degree]C has less non-saponified fat. Soap made from a large amount of waste edible oil. taking 34 days had much residual fat, proving these were insufficiently saponified. Slightly higher values were recognized in the soap from fresh oil for anisidine value (An.V), carbonyl value (CV), peroxide value (POV) and the content of oxidized fatty acids than in fresh oil itself. On the other hand, the An.V and CV in the soap made from thermally oxidized oil were lower than those for thermally oxidized oil itself. The An. V and CV in the soap made from waste edible oil were higher than those in waste edible oil itself. As the soap has been stored, all of the soap showed increase in the An.V, the CV, the POV and the oxidized fatty acid amount, but the fatty acid composition showed no change. 9 refs., 4 figs., 4 tabs.

Forests have become drawing attention as an absorption source of carbon dioxide, a greenhouse effect gas. This paper discusses significance of forests from viewpoints of their roles as diverse ecological systems and socio-economic values. Forest is a place for living and resting of all kinds of living organisms including plants, animals and microorganisms. Living forms in forests being affluent in kinds and large in amount bring great favor to human societies. Forests play diversified roles other than biological roles in addition to largely affecting heat distribution on the ground through evapotranspiration. These roles include suppression of erosion on ground surface, alleviation of micro climate by reducing wind velocity on the ground, and disaster prevention. Forests have an aspect of supply source of production resources for societies as well as an aspect of unused lands. Efficiency of converting solar energy by plants looks inferior to that of solar cells. Biomass may be regarded as regenerative energy limited to a case where excess production is utilized. 142 refs., 56 figs., 44 tabs.

Full Text Available Using data on the structure, conditions of occurrence (bedding, and the isotope composition of massive ice beds on the West coast of Baydaratskaya Bay it was established that the massive ice beds even occurring in the same outcrop may be related to different genetic types. There are two groups of the massive ice: 1 the «upper» thick (> 3 m massive ice beds composed by buried basal glacier ice; and 2 the «lower» small ice beds (< 3 m, formed both intrasedimentally and as a result of burial of initially surface ice bodies. Sand thickness which included both groups of the massive ice started its formation before the glacial ice burial. As a result of advancing and later degradation of the glacier, probably moving from the Pay-Khoy ridge or from the Polar Ural, its lower (basal parts were preserved within the permafrost thickness.

This paper reviews the researches relating to carbon dioxide circulation in oceans, and introduces the roles played by oceans in respect of the CO {sub 2} problem. Oceans occupy 70% of the globe {prime} s surface area, and contain 60 times as much of carbon as in the atmosphere. However, the amount of CO {sub 2} absorbed from the atmosphere into the oceans as has been estimated to date can not explain the carbon balance on earth. The exchange rate of CO {sub 2} between the atmosphere and the oceans was estimated from measurements of the partial pressure (PCO {sub 2}), and from behaviors of the radiocarbon ({sup 14} C). However, to raise the estimation accuracy, it is necessary to obtain data from the sea areas where observations are carried out only infrequently, and from the winter season during which the observation frequency is low. Identifying variations in organic and inorganic carbon amount generated by marine organisms is also important. Since more than 99.9% of carbon is present in the form of carbonate, it is required that its amount, and the amount of precipitation and dissolution per unit time be identified, and that CO {sub 2} removed from the carbon cycle be quantified. What is particularly required is the study of open-sea bottom deposits, and the coastal study with coral reefs as the main object. 40 refs., 30 figs., 11 tabs.

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

Full text:Objective: to assess the effect of radionuclide pollution of river water on the isolation rate of S. Tuphi at different times of the year. Materials and methods: Since the number of typhoid fever cases reported in the Mayluusuu Valley (23 tailing pits and 16 tailing dumps are located in the area) tends to increase after the mudslides we collected river water specimens considering all these factors. Water specimens were collected from the Mayluusuu River, Shaidan-sai River, Kara-Unkur River and Ak-Buura River. Bacterial inoculation was performed in accordance with standard procedures. Concentration levels of pesticides (DDT, DDE, DDD, GCCG {alpha}, {beta}, {gamma} Aldrin and Dieldrin) were measured with a spectrograph. The present work was done in the framework of the ISTC Project KR-1516. Results and discussion: Out of the total of 2360 water specimens collected from the Shaidan-Sai River, S. Typhi was isolated from one (0.04%) water specimen. No cases of S. Typhi isolation from the water specimens collected from the Kara-Unkur River were reported for the past 10 years. Out of the total of 8969 water specimens collected from the Ak-Buura River, isolation of S. Typhi was reported in 4 (0.044%) cases. Starting from 2006 typhoid fever cases have been reported in the winter and spring times among the residents of the Mayluusuu Valley. A total of 1200 patients with a presumptive diagnosis of typhoid fever were admitted to the hospitals during the period. S. Typhi was isolated from 2 out of the total of 51 (3.9%) water specimens collected from the Mayluusuu River in the winter time, 4 (2.4%) out of the total 164 - in the spring time, 3.4% and 4.5% in the summer and autumn, respectively. Concentration levels of thorium (Th) and uranium (U) were 0.025-0.045 mg/l and 0.35-15.0 mg/l. No traces of the pesticides were found in water specimens. DDE at concentration of 0.024 mg/l and GCCG {alpha} (0.06 mg/l) were found in silt specimens collected downstream the Ak

Memories of Statehood in the “Defter-i Genghis-name” »

Full Text Available The Turkic peoples of the Volga Region lost their statehood for centuries due to the Russian occupation of the Khanate of Kazan and Astrakhan in the mid–16th century. The memory of statehood among these peoples has been maintained and preserved for posterity through the oral historiography of the steppe. It comes as no surprise then that there has been an effort to create and strengthen the national identities in the post-Soviet Turkic republics with the successive publication of the latest editions of national epics and collections of historical stories. Research objectives and materials: This investigation focuses on one such source that forms part of the oral historiography of the steppe, a Genghis-name compiled and re­corded by an unknown author in the late 17th century. The chapter on Genghis Khan contains two stories that depict the various forms of organisational practices in nomadic states. The first was characteristic of the Golden Horde and the Nogai Horde at its zenith; it concerns the joint rule of the khan and the beglerbeg. The second depicts relations in the late Golden Horde and its successor states, in which the khan and the four chieftains constituted and led the country together. In the Genghis-name we could set the type of a super complex chiefdom headed by Temir Kutlu Khan with his four karačı biy’s of the clans Kiyat, Kongrat, Cathay, Saldzhut. Research results and novelty: It was possible to give an answer to the question why are so different the karačı biy’s of the Great Horde of those in the other late Golden Horde states. A historian can glean information from this story both on the age in which the source was created and on practices of nomadic rule: What stands out above all is that the clans had the right to resist and that they were able to shift away from their tyrannical rulers without any consequences and seek a new ruler for themselves. The steppe lacked the po­wer of law that would have enabled the

To study and/or develop the vehicle motion of a braking in turns theoretically, the cornering characteristics of the tire under the action of braking forces must be required. On the other hand, such data are very few to be published and also there be few tire testing machine to be able to use. The authors tried to derive such data from the vehicle behaviors in steady turns and braking in turns. Because each wheel loads are unknown factors, the two wheeled vehicle model are employed in analysis. The methodology of analysis and the reasonable results are presented in this paper. 5 refs., 10 figs., 2 tabs.

This paper discusses hydrogen fueled automotive engines. Because hydrogen has a very wide ignition mixture ratio limit for spark ignition engines, very lean combustion is possible without a need of throttling, and thermal efficiency in partial load is high. Thermal efficiency while a car is being driven is reportedly higher by 30% to 50%. Values for CO and CH in exhaust gas are negligible, while NOx is at about the same degree as in gasoline engines, which can be made extremely low during lean burn operation. The spontaneous ignition temperature is higher by about 200 degrees C than that of light oil, which presents difficulty in use for diesel engines. Because of small ignition energy and high combustion velocity, excessively early ignition and reverse ignition can occur easily. Hydrogen would be promising if new manufacturing systems are developed and production cost is reduced, and on the other hand, if petroleum price rises sharply. Hydrogen is also expected as a measure to prevent pollution, including that from soot, odor and CO2. The largest difficulty is in the transportation method, and the only possible method at the present is transportation in liquefied hydrogen form. However, practical application will have such problems as tanks, feeding devices, and cost. Development is desired on light-weight metallic hydrides. Technologies for safety and engine performance must also be developed. (NEDO)

The Global Aerosol/Radiation Experiment (GAREX) research programs, carried out in the Kara-Kum desert and in the Arctic and Kamchatka peninsula, has yielded the following conclusions: In the presence of liquid or particulate aerosols, the albedo of the underlying surface/atmosphere system increase over a weakly reflecting surface (water) and decreases over a highly reflecting surface (snow, ice). The albedo of ice of varying concentration and type ranges from 0.4 to 0.8 according to observations from an altitude of 200 m, reaching a maximum in the visible range of the spectrum. The albedo of clouds over the Arctic is noticeably greater than that of similar clouds over a city, over dry land, or over water in the European part of the USSR. The presence of particulates from volcanoes increases the albedo of clouds, but their influence is small in comparison with anthropogenic aerosols (mostly soot). The emissivity of clouds in the Arctic is less than unity, due to the predominance of ice crystals. In the Arctic, underlying surfaces typically have a large anisotropic reflection. 8 references, 3 figures, 2 tables.

1995-01-01

As part of the International Arctic Seas Assessment Project (IASAP) of IAEA a working group has been created to model the dispersal and transfer of radionuclides released from the radioactive waste disposed of in the Kara Sea. The aim of the benchmarking work is to quantitatively assess the reliability of the models, which would lead ultimately to the evaluation of consensus/best estimates of the concentration fields to be used in the radiological assessment. The results from the benchmarking have been compared and the results of the comparison are summarised in terms of agreement in maximum concentrations and when the maximum concentrations occurred.

In an attempt to resolve the controversy as to whether Arctic sea ice loss leads to more mid-latitude extremes, a metric of finite-amplitude wave activity is adopted to quantify the midlatitude wave activity and its change during the observed period of the drastic Arctic sea ice decline in both ERA Interim reanalysis data and a set of AMIP-type of atmospheric model experiments. Neither the experiment with the trend in the SST or that with the declining trend of Arctic sea ice can simulate the sizable midlatitude-wide reduction in the total wave activity (Ae) observed in the reanalysis, leaving its explanation to the atmospheric internal variability. On the other hand, both the diagnostics of the flux of the local wave activity and the model experiments lend evidence to a possible linkage between the sea ice loss near the Barents and Kara seas and the increasing trend of anticyclonic local wave activity over the northern part of the central Eurasia and the associated impacts on the frequency of temperature extremes.

Full Text Available India is a uniquely rich country thanks to its historical characteristics and complex mixture of different races, cultures and religions. The diversity of the religious groups has particularly affected the decorative arts, which have generated another form of diversity and richness. Every religious group built their own houses of worship and decorated them in accordance with their beliefs because of the close relationship between religion and decoration. Many buildings containing Turkish overtones have been constructed in India, particularly in Agra, during the Mughal era. The style of Kara Memi, a sixteenth century Ottoman painter, draws attention with the decoration of the buildings constructed during the Shah Jahan era. Of them, the most popular is the Taj Mahal. It is well known that the Ottomans respected and appreciated the artistic characteristics, particularly the architecture, of the region instead of acting in a dominating manner. Thus, we can consider the relationship between the Ottomans and Mughal Empire is similar only in terms of style. Cooperation was present between them, and artistic transfers between these two empires were thus inevitable.

Radionuclides in the Arctic seas from the former Soviet Union: Potential health and ecological risks

International Nuclear Information System (INIS)

Layton, D.W.; Edson, R.; Varela, M.; Napier, B.

1999-01-01

The primary goal of the assessment reported here is to evaluate the health and environmental threat to coastal Alaska posed by radioactive-waste dumping in the Arctic and Northwest Pacific Oceans by the FSU. In particular, the FSU discarded 16 nuclear reactors from submarines and an icebreaker in the Kara Sea near the island of Novaya Zemlya, of which 6 contained spent nuclear fuel (SNF); disposed of liquid and solid wastes in the Sea of Japan; lost a 90 Sr-powered radioisotope thermoelectric generator at sea in the Sea of Okhotsk; and disposed of liquid wastes at several sites in the Pacific Ocean, east of the Kamchatka Peninsula. In addition to these known sources in the oceans, the RAIG evaluated FSU waste-disposal practices at inland weapons-development sites that have contaminated major rivers flowing into the Arctic Ocean. The RAIG evaluated these sources for the potential for release to the environment, transport, and impact to Alaskan ecosystems and peoples through a variety of scenarios, including a worst-case total instantaneous and simultaneous release of the sources under investigation. The risk-assessment process described in this report is applicable to and can be used by other circumpolar countries, with the addition of information about specific ecosystems and human life-styles. They can use the ANWAP risk-assessment framework and approach used by ONR to establish potential doses for Alaska, but add their own specific data sets about human and ecological factors. The ANWAP risk assessment addresses the following Russian wastes, media, and receptors: dumped nuclear submarines and icebreaker in Kara Sea--marine pathways; solid reactor parts in Sea of Japan and Pacific Ocean--marine pathways; thermoelectric generator in Sea of Okhotsk--marine pathways; current known aqueous wastes in Mayak reservoirs and Asanov Marshes--riverine to marine pathways; and Alaska as receptor. For these waste and source terms addressed, other pathways, such as atmospheric

Confluence and redistribution of Atlantic water in the Nansen, Amundsen and Makarov basins

Full Text Available The waters in the Eurasian Basin are conditioned by the confluence of the boundary flow of warm, saline Fram Strait water and cold low salinity water from the Barents Sea entering through the St. Anna Trough. Hydrographic sections obtained from RV Polarstern during the summer of 1996 (ACSYS 96 across the St. Anna Trough and the Voronin Trough in the northern Kara Sea and across the Nansen, Amundsen and Makarov basins allow for the determination of the water mass properties of the two components and the construction of a qualitative picture of the circulation both within the Eurasian Basin and towards the Canadian Basin. At the confluence north of the Kara Sea, the Fram Strait branch is displaced from the upper to the lower slope and it forms a sharp front to the Barents Sea water at depths between 100 m and greater than 1000 m. This front disintegrates downstream along the basin margin and the two components are largely mixed before the boundary current reaches the Lomonosov Ridge. Away from the continental slope, the presence of interleaving structures coherent over wide distances is consistent with low lateral shear. The return flow along the Nansen Gakkel Ridge, if present at all, seems to be slow and the cold water below a deep mixed layer there indicates that the Fram Strait Atlantic water was not covered with a halocline for about a decade. Anomalous water mass properties in the interior of the Eurasian Basin can be attributed to isolated lenses rather than to baroclinic flow cores. Eddies have probably detached from the front at the confluence and migrated into the interior of the basin. One deep (2500 m lens of Canadian Basin water, with an anticyclonic eddy signature, must have spilled through a gap of the Lomonosov Ridge. During ACSYS 96, no clear fronts between Eurasian and Canadian intermediate waters, such as those observed further north in 1991 and 1994, were found at the Siberian side of the Lomonosov Ridge. This indicates that

1999-11-10

It has been clarified that the corrosion of concrete in sewage facilities is caused by the action of specific microorganism. The corrosion of concrete is caused by the complicate interaction of chemical substances and microorganisms existing in sewage water. As microorganisms related to this phenomenon, lead sulfate reductase and sulfur oxidase are well known. This paper introduces antimicrobials for concrete using zeolite as a main component and a concrete containing these antimicrobials, which were developed for killing or suppressing the generation of these microorganisms causing the corrosion of concrete. The sales results during 2 years since the start of the sales in May 1997 was 16 tons for antimicrobials including zeolite-supported silver - copper catalyst, and 8,138 tons for antimicrobial concrete. Sixty-eight companies have organized , which will promote the popularization and technical guidance of antimicrobial concrete. (NEDO)

Bacteria such as Zymomonas atracts attention in production of ethanol from carbohydrates in addition to yeast used for a long time, however, Zymomonas ferments only glucose, fructose and sucrose. After searching microbes in the nature with excellent properties in fermentation ability and salt resistance, a new Gram-negative bacterium has been isolated from a certain tree sap which is suitable for production of ethanol from maltose and starch hydrolyzate. The features of cell morphology of the new bacterium are: bacillus, peritrichous, no sport forming, Q-9 in quinone system, and an anaerobic Gram-negative bacterium. It utilizes maltose, sorbitol and maltose and produces [alpha]-glucosidas but no [beta]-galactosidase nor arginine dihydrase. The strain T109 is deposited as FERM BP-3292 to the Industrial Research Institute of Microbiology. 2 figs., 2 tabs.

Free convective heat loss from cavity-type solar furnace; Solar receiver kara no shizen tairyu ni yoru netsusonshitsu

Fujii, I; Ito, N [Meiji University, Tokyo (Japan)

1996-10-27

Free convective heat loss from solar heat receivers was studied, using three laboratory model receivers (different in depth L and aperture diameter d) heated by electric heaters. Most of the heat produced by heaters was transmitted to the air inside. The cylindrical vessel walls were fully insulated against heat. Heat loss being supposed to result mainly from transfer by free convection, the experiment results were edited by use of Nusselt number Nu and Rayley number Ra. Relations between Nu(D/d){sup m1} and Ra(L/D){sup m2} were plotted in a chart. Here, D is the receiver inner diameter, and m1 and m2 are constants that can be determined by computation. Tests points were provided approximately lineally, irrespective of D, L, or receiver inclination. Air currents were found to produce one or more swirls inside, thanks to the current visualization technique, when the receiver inclination was not sharper than 120{degree} (except 0{degree}). The number of swirls increased as the inner wall temperature rose. This kind of behavior of air currents directly affects the degree of heat loss. 9 refs., 4 figs.

Halocline water formation in the Barents Sea

Science.gov (United States)

Steele, Michael; Morison, James H.; Curtin, Thomas B.

1995-01-01

Hydrographic data from the first phase of the Coordinated Eastern Arctic Experiment (CEAREX) are analyzed. The data consist of temperature and salinity measurements made by a ship-based conductivity-temperature-depth (CTD) instrument and by a drifting SALARGOS buoy. These data were collected in the autumn and early winter of 1988-1989 in the northern Barents Sea, mostly in ice-covered conditions and then across the marginal ice zone (MIZ). The data show that relatively warm, salty water of Atlantic origin is modified by air cooling and ice melting to produce lighter water that has properties identical to (lower) halocline water found in the Arctic Ocean. This occurs mostly at the MIZ and to a lesser degree within the ice pack itself. At the MIZ the halocline water subjects underneath the lighter meltwater that resides directly under the ice pack; geostrophic velocity calculations indicate that it then turns eastward and flows toward the Kara Sea, in keeping with previous chemical tracer analyses. A rough calculation reveals that the amount of halocline water formed in this way in the Barents Sea and Fram Strait is 30-50% of that formed by ice growth in eastern Arctic polynyas.

Investigation of geochemical characteristics of some natural water systems by nondestructive radioactivation analysis

Draskovic, R.

1977-01-01

In this thesis the new theoretical and systematized approaches to the investigation of continental water systems (rivers, lakes, swamps etc) with the aim of its biogeochemical characterization are given and discussed. By nondestructive radioactivation analysis some elements (Cr, Fe, Co, Sb, Sc, Na acro and trace elements level) in components of investigated water system are determined. These elements has been determined in materials dissolved in water, suspended and bed materials, soils and the living matter populating the rivers systems Danube, Sava, V.Morava, Tisa, Karas and some lakes also (plankton, algae, benthos, crustacea, benthos, shalls and fishes) in Yugoslavia. The results are presented and discussed on the basis of parameters ''content of elements'' (new theoretical approaches) for these systems (Csub(w)-water; Csub(s)-suspended and bed materials; Csub(t)-soils; Csub(vivo)-living matter: plankton - Csub(p); aglae - Csub(al); benthos - Csub(b); crustacea - Csub(c); fishes - Csub(f)) expressed in ppm. Distribution on parameters (Fsub(x,y)) for the pairs of components of water systems also are given. The ''contents of elements'' - parameters are biogeochemical standards characterizing investigated water systems and ecological and environmental important parameters, too

Monitoring Murder Crime in Namibia Using Bayesian Space-Time Models

Directory of Open Access Journals (Sweden)

Isak Neema

2012-01-01

Full Text Available This paper focuses on the analysis of murder in Namibia using Bayesian spatial smoothing approach with temporal trends. The analysis was based on the reported cases from 13 regions of Namibia for the period 2002–2006 complemented with regional population sizes. The evaluated random effects include space-time structured heterogeneity measuring the effect of regional clustering, unstructured heterogeneity, time, space and time interaction and population density. The model consists of carefully chosen prior and hyper-prior distributions for parameters and hyper-parameters, with inference conducted using Gibbs sampling algorithm and sensitivity test for model validation. The posterior mean estimate of the parameters from the model using DIC as model selection criteria show that most of the variation in the relative risk of murder is due to regional clustering, while the effect of population density and time was insignificant. The sensitivity analysis indicates that both intrinsic and Laplace CAR prior can be adopted as prior distribution for the space-time heterogeneity. In addition, the relative risk map show risk structure of increasing north-south gradient, pointing to low risk in northern regions of Namibia, while Karas and Khomas region experience long-term increase in murder risk.

The aims of this study were: 1) to continue the investigation of distribution of radionuclides in the principal components of the Techa river, and 2) to get the first estimate of the contamination of sediments of the Iset, Tobol, Irtysh and Ob rivers. The samples from the Irtysh river were collected in 1993 nine km in front of confluence of the Irtysh with the Ob river. The mean Cs-137 concentration in the sediments did not show any clear trend. The sediments from the Ob river were collected in 1992 near Labitnangi, situated about 300 km from the outlet of the Ob into the Kara Sea. In 1994 samples were collected five km in front of and five km after confluence with the Irtysh river. All results are summarized in a table. It appears that the Cs-137 levels in the Ob sediments, before and after confluence with Irtysh, do not change significantly. It is difficult to see any systematic changes in Cs-137 concentrations with depth. In some cases the top five cm show higher concentrations than the deeper layers. 7 refs., 1 tab

Full Text Available This study analyzes whether or not communication skills and self-esteem of vocational school students can predict their psychological resilience. The data of the study were collected from a total of 295 vocational school students including 147 female and 148 male in Burdur and Isparta. The study benefited from the Ego Resiliency Scale developed by Block and Kremen (1996 and adapted by Karaırmak (2007, the Communication Skills Evaluation Scale developed by Korkut (1996, and the Rosenberg Self Esteem Scale developed by Morris Rosenberg (1965. The study made use of the standard multiple regression analysis in order to prove the power of the assessment of communication skills and self-esteem to predict psychological levels of resilience of vocational school students. The data were tested on a 0.05 level of significance. This study shows that the assessment of communication skills and self-esteem positively co- relates with the personal strengths of pulling oneself together. The positive self-assessment predicts self- esteem positively and significantly as well. A positive sense of an individual’s about oneself positively co- relates with high self-esteem.

The suspention of TiO {sub 2} (rutile structure, 99.9%, 300 mesh) photocatalyst in ethanol was irradiated under ultraviolet light in an argon atmosphere at 25 centigrade. Acetaldehyde, methane and hydrogen were detected as products. When the photocatalysis of TiO {sub 2} itself was examined comparing with the result of blank test without using catalyst, the activity of TiO {sub 2} was confirmed only for the formation of acetaldehyde among the products. The yields of acetaldehyde increased with increasing addition of catalyst. The increasing rate of methane yields was rather small and the methane yields were lower than those in the blank tests. The hydrogen yields were almost same as in the blank tests. Acetal was formed in the blank test but was not formed with addition of TiO {sub 2}. It was provided that TiO {sub 2} was an effective catalyst for the formation of acetaldehyde. 6 ref., 5 figs.

Demand has been building up for an individual dry type scrubber for treating exhaust gas from the semiconductor manufacturing process. Some factors for the wide acceptance of such a scrubber would be the capability for complete treatment, easy maintenance and safety features, etc. Practical gas analysis and optimum scrubbing techniques would have to be applied, as well as effective monitoring, alarm, and fail-safe techniques. The overall exhaust gas line, i.e. the line connecting the scrubber system and the upstream process, including that extending to pump system, has to be fully considered for enabling effective scrubbing performance. Such factors, which have until now not been given any priority, would have to be fully studied for the development of a practical, individual dry type scrubber. Cooperation on this matter from the semiconductor manufacturing industry would also be essential. 6 refs., 3 figs., 5 tabs.

Discussions were given on separation and recovery of leaded-frame metals from an integrated circuit (IC) package. A printed wiring board in an electronic device is mounted with an IC package molded with an IC as a major component, and composed of IC chips, leaded-frame metals (the pin section retains the IC chips safely in a mold, and plays a role of terminal with an external circuit), and mold material (thermally hardened and reinforced resin). Quantity of IC packages discarded as a result of the deterioration due to aging is increasing year after year. IC package test pieces were crushed in a mortar, selected of metals manually, and classified by using a magnet and a sieve. The leaded-frame metals were easily separated from the mold material by crushing, and capable of being recovered by using a magnet. However, since the recovered leaded-frame metals are alloys having different compositions, how each metal component could be separated and refined is an important problem to be solved. For the time being, the metals may be utilized as structural materials for building materials by melting and alloying the leaded-frame metals. 10 refs., 7 tabs.

This report describes the historical procedure of a bacterial test for a certain respective bacteria, and also describes the removal of micro-organisms by a water treatment and treatment with disinfectants. The disinfection is made mainly on basis of foreign literature. This is because there exist few literature published in Japan. In a good sense, this is because of the Japanese habit of drinking raw water which has contributed to high level of facilities and the maintenance. If seen from a different viewpoint, the prsent concern is concentrated to a contamination of the underground water by organic solvent and the counter measure against such minute quantity of organic chemicals as trihalomethane and the agricultural chemicals in the golf courses. From the consumers {prime} standpoint, these are of the level of problems that only one affected person increases per year for 100,000 inhabitants even if they continue to drink such drinking waters continuously through their life years. The reality is that it is remote from the realities in life. 37 refs., 9 tabs.

The Potential and Challenges of Using Soil Moisture Active Passive (SMAP Sea Surface Salinity to Monitor Arctic Ocean Freshwater Changes

Directory of Open Access Journals (Sweden)

2018-06-01

Full Text Available Sea surface salinity (SSS links various components of the Arctic freshwater system. SSS responds to freshwater inputs from river discharge, sea ice change, precipitation and evaporation, and oceanic transport through the open straits of the Pacific and Atlantic oceans. However, in situ SSS data in the Arctic Ocean are very sparse and insufficient to depict the large-scale variability to address the critical question of how climate variability and change affect the Arctic Ocean freshwater. The L-band microwave radiometer on board the NASA Soil Moisture Active Passive (SMAP mission has been providing SSS measurements since April 2015, at approximately 60 km resolution with Arctic Ocean coverage in 1–2 days. With improved land/ice correction, the SMAP SSS algorithm that was developed at the Jet Propulsion Laboratory (JPL is able to retrieve SSS in ice-free regions 35 km of the coast. SMAP observes a large-scale contrast in salinity between the Atlantic and Pacific sides of the Arctic Ocean, while retrievals within the Arctic Circle vary over time, depending on the sea ice coverage and river runoff. We assess the accuracy of SMAP SSS through comparative analysis with in situ salinity data collected by Argo floats, ships, gliders, and in field campaigns. Results derived from nearly 20,000 pairs of SMAP and in situ data North of 50°N collocated within a 12.5-km radius and daily time window indicate a Root Mean Square Difference (RMSD less than ~1 psu with a correlation coefficient of 0.82 and a near unity regression slope over the entire range of salinity. In contrast, the Hybrid Coordinate Ocean Model (HYCOM has a smaller RMSD with Argo. However, there are clear systematic biases in the HYCOM for salinity in the range of 25–30 psu, leading to a regression slope of about 0.5. In the region North of 65°N, the number of collocated samples drops more than 70%, resulting in an RMSD of about 1.2 psu. SMAP SSS in the Kara Sea shows a consistent

Model simulation technology is important for automobiles development. Especially, for the investigations concerning to ABS, TRC, VDC, and so on, the model should be the one which can simulates not only whole behaviors of the automobile, but also such internal information as torque, acceleration, and, velocity of each drive shafts, etc.. From this point of view, 4-wheels simulation model which can simulates almost over 50 items, was made. On the other hand, technique of 3-D image processing using 2 video cameras was adopted to identify the model. Considerably good coincidences were recognized between the simulated values and measured ones. 3 refs., 7 figs., 2 tabs.

For many years the Mining and Chemical Combine was producing weapon-grade plutonium in three nuclear plants on the banks of the river Yenisei south of the city Krasnoyarsk, Siberia. Artificial radionuclides were found in sediments of the river in close distance to the plants as well as over the whole length of the river up to the icy Kara-Sea. In order to reconstruct the discharge into the river and to understand migration processes dating of the activity in undisturbed sediment cores had to be done. Due to vertical advection of water through the sediments the age of sediment layers and the age of the activity therein have to be distinguished. The following methods of dating have been analyzed: The Pb-210 gamma-spectrometric method which showed to be not applicable, the Eu-152/Eu-154 ratio, the Po-210 alpha-spectrometric method, and modelling of the vertical distribution of activity in the sediment. Furthermore, ICP-MS analyses of Np, Am and Pu isotopes have been used to perform dating analyses. The results of the different methods are compared in order to ensure a proper understanding of the history of the activity and of the processes within the sediment. (author)

Full Text Available Population densities of harmful and predatory insects have been compared in six table (Trakya İlkeren, Alphonse Lavallée, Tekirdağ Çekirdeksizi, Cardinal, Italia, Amasya beyazı x 28/259-1 and six wine (Cabernet Sauvignon, Merlot, Syrah, Kalabaki, Sauvignon Blanc, Özer Karası grape varieties in Gokceada between 2008 and 2011. No difference was determined among table grape varieties. Trakya llkeren has been the most suitable grape variety for Gokceada as it is rarely infested by the pests. Population density of Colomerus vitis Pgst. was statistically different in wine varieties in 2010. Cabernet Sauvignon has continuously been infested by the pest. Arboridia adanae Dlabola and Thrips spp. were harmful in Cabernet Sauvignon in 2011. Merlot has been infested with higher populations of insect pests in some years. Hence, Cabernet Sauvignon and Merlot should not be preferred in Gokceada. Kalabaki had the lowest population density. Effect of four combinations of green manure, farm manure and olive cake compost was observed on the population density of harmful and beneficial insects on Trakya Ilkeren and Cabernet Sauvignon. The combinations tested had no important effect on the population density of insect pests and predators. Organic fertilization program should be selected according to what grape and vine tree need.

Therefore, in this study, we describe a case of Streptococcus pneumoniae sepsis in a young woman with previously undiagnosed SLE. Case report: A 23-year-old female patient was admitted to our outpatient clinic complaining of high fever (40°C, chills, fatigue, generalized myalgia, and cough with brown sputum for 5 days. Blood cultures grew gram-positive coccus defined as S. pneumoniae using standard procedures. Antinuclear antibody was positive at a titer of 1/1,000, and anti-double-stranded DNA was positive at 984 IU/mL. She was diagnosed with SLE. Her respiratory symptoms and pleural effusion were considered to be due to pulmonary manifestation of SLE. Conclusion: The underlying immunosuppression caused by SLE could have predisposed the patient to invasive pneumococcal disease. It may also occur as a primary presenting feature, although a rare condition. Keywords: Streptococcus pneumoniae, sepsis, systemic lupus erythematosus

The great challenges in Arctic Ocean paleoceanography

Despite the importance of the Arctic in the climate system, the data base we have from this area is still very weak, and large parts of the climate history have not been recovered at all in sedimentary sections. In order to fill this gap in knowledge, international, multidisciplinary expeditions and projects for scientific drilling/coring in the Arctic Ocean are needed. Key areas and approaches for drilling and recovering undisturbed and complete sedimentary sequences are depth transects across the major ocean ridge systems, i.e., the Lomonosov Ridge, the Alpha-Mendeleev Ridge, and the Chukchi Plateau/Northwind Ridge, the Beaufort, Kara and Laptev sea continental margins, as well as the major Arctic gateways towards the Atlantic and Pacific oceans. The new detailed climate records from the Arctic Ocean spanning time intervals from the Late Cretaceous/Paleogene Greenhouse world to the Neogene-Quaternary Icehouse world and representing short- and long-term climate variability on scales from 10 to 10 6 years, will give new insights into our understanding of the Arctic Ocean within the global climate system and provide an opportunity to test the performance of climate models used to predict future climate change. With this, studying the Arctic Ocean is certainly one of the major challenges in climate research for the coming decades.

The Republic of Togo is a land of 21,622 square miles on the west coast of Africa, 8 degrees north of the equator. The country is divided between the Kabye people in the north (22%) and the Ewe people in the south (35%). The president, General Gnassingbe Eyadema, is a Kabye. The population of 3.3 million (1988) is growing at the rate of 3.3%/year, despite an infant mortality of 107 deaths/1000 live births and a life expectancy of only 54 years. The total fertility rate is 6.5 children/woman. The birth rate is 47 births/1000 population, and the death rate is 14/1000. Population growth, especially in the cities of Lome and Kara, where 1/4 of the population lives, is considered a major threat to development. A Demographic and Health Survey has been taken, and a Conference on Population and Development was held in Lome in 1987 to draft a national population policy statement. Family planning services need to be implemented to raise the contraceptive prevalence rate above its present 2%, and the population needs to be redistributed, but this requires investment of funds currently being used to service the foreign debt. The country's gross national product is only $300 per capita.

This paper presents the cyclone shelters in Bangladesh. Bangladesh has been damaged by flooding due to big storm surges caused by cyclone every year, losing many human lives and properties. The sea within 100km apart from the coast is gradually shoaling beach shallower than 10m because of sediment transport by the Ganges. Consequently, huge storm surges are easily caused by cyclone generated in Bay of Bengal. The cyclone shelter is only one refuge from cyclone. Construction of the cyclone shelters was opened in the 1960s, and the public work department (PWD) in the government had constructed the cyclone shelters under support by International Development Association (IDA) since 1970. At the same time, BDRCS had constructed the shelters under support by Red Cross Societies of every country, and positive NGOs such as Caritas had been also in the same action. Because many cyclone shelters became too old for use, construction of new cyclone shelters was opened again just after disaster in 1991. 2 refs., 8 figs., 1 tab.

Presently, the aluminum demand in Japan is approximately 3.8 million tons, and the aluminum discharged as scrap reaches approximately 1.7 million tons/year. Out of the discharged scrap, 54% is recovered as the secondary metal, and the rest, 0.77 million tons, is not recovered and dumped for land reclamation. In future, if the present cascade type recycling goes on, it is predicted that a gap between supply and demand of about 0.5 million tons will arise. To cope with this problem, the following are the measures to be taken : 1) development of the technology to promote the use of recycled aluminum metal for automobiles in which a lot of aluminum is most likely to be used because of the increasing fuel consumption, etc. 2) establishment of a recycling system by which the waste sash discharged in quantity from the construction field is again used as sash. From the two points of view, which are needed in the case of using a lot of aluminum for automobiles, the heightening of competitiveness in the aluminum industry and the recycling in which the aluminum expanded materials used for automobiles are efficiently recycled as expanded materials in the recycling economic system, this survey extracted problems and made proposals, overlooking the state of the aluminum use in automobiles, state of the treatment of used cars, state of manufacturing/processing technology of aluminum products.

This paper describes the achievements in fiscal 1998 on developing ITS technology using clean energy driven automobiles. Development is intended on an efficient management and control method for EV car rentals in tourist resort areas using the ITS technology from the viewpoints of reducing road traffic load and global environment problems. The development items include a control center system, a system to control battery charging status at the center, a battery charging determination algorithm, and a car navigation and bi-directional communications mounting system. The system development has been completed nearly completely, having attained relatively high user satisfaction. However, because of the experimental rented cars having long mileage, there were few chances of verifying the charge determination algorithm and the functions of the ITS. Investigations were carried out on technological trends in overseas countries on EV and ITS, and on commuter car introduction projects. Structuring the hardware for a commuter EV system is not too difficult if the presently available EV and ITS technologies are used. However, in advancing commercialization, there are such assignments as establishment of software, operation patterns, and interfaces that enhance user convenience and profitability. (NEDO)

Receiving subsidies from MITI, NEDO carried out this project in fiscal 1995 and 1996 as a joint research with Technology Research Association for Phosphoric Acid Fuel Cell Power Generation System and others. The project aimed at developing the accelerated test method which can evaluate in a short time the cell life of phosphoric acid fuel cells (PAFC) and the lowering of characteristics. The accelerated test method of PAFC life is thought to be a tool indispensable for the promotion of commercialization, but the accelerated test method like the usual material evaluation has not yet been established. To solve this problem, procedures were developed to rationally plan the accelerated test on short stacks of full scale based on the small cell test data. Here, to rationally estimate the operational state under actual conditions based on the data on the accelerated test, it is necessary to fully understand the mechanism of deterioration of PAFC. By conducting in parallel the element study for the basic elucidation of cell deterioration phenomena, obtained was the useful information/knowledge which back up the results of the accelerated test scientifically. 168 figs., 33 tabs.

The members of MHD project examination subcommittee made an investigative tour of the U.S. on the state of development of MHD generation. This report of the 2nd part explains opinions and the present status of the R and D on MHD generation by each of the 19 institutions visited. The U.S. research on MHD generation is under the leadership of DOE, whereby the budget for the development is so large as nearly one hundred million dollars have been provided for several years. The purpose is the effective use of domestic coal. General Electric is of the opinion that a combined gas turbine system will be put to practical use earlier because MHD takes time for practicability despite its highest efficiency in coal-utilized power generation. Yet, GE thinks MHD will be more attractive in the future. Reynolds Metal is considering application of MHD generation to the electro-chemical industry at present. According to Reynolds, combined supply of electric output and heat of MHD can reduce the use of calorie per ton of aluminum from 240 MBTU to 100. Montana Power is promoting practicability through a combined plan with DOE-built MHD generation. (NEDO)

Solvent extraction was investigated as a method of recovering Au from sulfuric acid solution containing thiourea. With the objective of improving Au extraction by die-(2-ethylhexyl) phosphoric acid (D2EHPA) and tri-n-octylamine (TOA), effects of D2EHPA, TOA, TBP (tri-n-butyl phosphate), and trioctyl phosphine oxide (TOPO) as extractants were investigated. When mixed extractant of D2EHPA with TBP or TOPO, or mixture of TOA with TBP or TOPO was used, synergistic effect was observed for the extraction of AU, and they were proved to be effective for the improvement of Au extraction. When D2EHPA/TBP and D2EHPA/TOPO mixtures were used, the extraction of Fe was suppressed on the contrary, and they were found to be effective for the separation of Au and Fe. Benzene used as diluent seemed to be favorable to both the extraction of Au and the separation of Au and Fe. The selection of sulfuric acid concentration seemed to be an important factor for the extraction efficiency of Au and the separation efficiency of Au and Fe, while little effect was observed with the concentration of thiourea. 4 refs., 8 figs., 4 tabs.

The Hokkaido Underground Resources Investigation Institute has prepared in 1995 a detailed temperature gradient chart that shows local anomalies around volcanoes. This paper describes an attempt to derive crustal temperature structure of Hokkaido from the above data. The model was hypothesized as a primary model in which no thermal convection exists. In volcanic and geothermal areas which show a temperature gradient of more than 100 {degree}C km {sup -1}, a solidus temperature is reached at a depth shallower than 10 km. Below the volcanic chain forming the Chishima arc, a partially melted region exists in a width of about 100 km. Most of the areas in the southern Hokkaido have the temperature reached the solidus temperature in the crust. On the other hand, in most of the areas of the forefront side, no solidus temperature is reached in the crust. In the temperature structure of a cross section crossing almost orthogonally with the volcanic front passing through Mt. Daisetsu, a high temperature area reaches to a shallow portion beneath Mt. Daisetsu, where the depth at which the solidus temperature is reached is 10 km or shallower. The range of area where the solidus depth is shallower than 10 km has a south-west width of about 40 km. This means that a partially melted area with a size of 40 km in the horizontal direction exists at a depth of several kilometers. 20 refs., 3 figs.

The cold crucible is a high-frequency induced heating melting process consisting of the cold copper crucible, coil, and charge. The levitation type crucible is of the cup type device, with the magnetic field concentrated to the vicinity of the hole in its bottom, so that the whole charge is melted and non-contact retention is achieved by the Lorentz`s force. However, when the vacuum suction method or the tilting method is used to take out or pour a charge from the crucible, defects such as contamination due to contact with the wall and heat transfer are unavoidable. This report proposes a new pouring method using the electromagnetic force, providing the logical and experimental examinations. As a result of analysis of the electromagnetic force applied on the side of the charge levitating in the crucible, it was confirmed that changing the current value through the coil varies the pouring phenomenon, depending on the followability of the levitating position, and changing the relative position of the coil to the crucible enables pouring. Thus, the pouring form measuring method was established. 9 refs., 10 figs., 1 tab.

For active safety enhancement, drivers will be provided with information and warning that will help them drive with safety. Studies are under way about functions to facilitate drivers' perception and to lighten the burdens imposed on them. As for accident avoidance techniques, onboard systems will perform controls involving vehicle maneuver for safety enhancement. This includes the improvement of vehicle maneuvering performance, in addition to brake control and steering control, for lightening drivers' burdens and for complementing their operating skill. Danger avoidance is based on the concept that the related system is to work in case warnings alone are not enough to avoid a collision. Full automation will be implemented by two ways, the autonomous way aided by the existing infrastructures such as GPS (Global Positioning System) or the way in which infrastructures to be newly built will be utilized. Passive safety technologies aim at minimizing damage upon collision, and involve structural improvement, air bags, etc. Disaster aggravation prevention means to prevent disaster from spreading after collision. Communication is one of safety-related elements on which studies will continue. Under the Phase 2 ASV program, research and development will be conducted for putting passenger cars to practical use, and the same will be conducted, in the case of large vehicles and motorcycles, for the construction of their prototypes.

Full Text Available Beehive houses of Suruç are completely built from sun dried mudbrick. Traditionally, rural house of Suruç plain is beehive houses. It has known that these houses have been used for centuries. These houses rooms have square plan and each room have conical roof. In terms of their own characteristic, Suruç beehive houses different from other conical or dome roofed houses such as beehive house of Harran, Trullo and Clochán. Basically there are four usage spaces; living rooms, designs of granaries, barn or folds and haylofts which are respectively arranged from south to north. These usage spaces are connected to each other with eyvans or gates without door. As requirement of rural life, these houses have some outbuildings such as tendur (tandoor, kadin (hayloft, gom (open folder, ça’l, lod and seki (terrace. Due to some environmental and socio-economic problems have caused migration from countryside to cities during the last 30 years. As a result of this, the Suruç beehive houses have either disused or abandoned completely. In addition, especially in last 30 years, the villagers in the area have begun to prefer building the reinforced concrete houses. This has led some of the Suruç beehive houses either to be destroyed or abandoned. Recent survived examples of these houses can be seen in Kara, Yatırtepe and Boztepe villages

Both the timing of maximum extent and subsequent pace of retreat of the interconnected Eurasian (British-Irish, Scandinavian, Svalbard-Barents-Kara Sea) Ice Sheets were spatially variable likely reflecting contrasts in response to forcing mechanisms, geographical settings and glacial dynamics both between individual ice sheets and ice-sheet sectors. For example the maximum limit along the western continental shelf edge was reached up to 3,000 years earlier than the maximum, mainly terrestrial, limits in the east. We present new time-slice reconstructions of the ice-sheet evolution through the last deglaciation based on a compiled chronology of over 5,000 dates and published ice-margin positions. Ice-sheet margins are depicted every 1,000 years (25-10 kyr) and include uncertainty estimates (represented by maximum, minimum and most-credible lines). The new ice-sheet scale reconstructions summarise and provide the means for direct comparison of the empirical geological record against simulations of the deglacial ice-sheet evolution from numerical and isostatic ice-sheet modelling and the timing of abrupt events observed in deglacial climate and ocean records. The reconstruction process has identified both instances of conflicting evidence and gaps in the geological record that should be a focus for future studies. This work is part of an on-going project to reconstruct the changing limits of the Eurasian Ice Sheets through the last glacial cycle (www.uib.no/project/dated).

The present study investigates how much a realistic Arctic sea ice condition can contribute to improve simulation of the winter climate variation over the Eurasia region. Model experiments are set up using different sea ice boundary conditions over the past 24 years (i.e., 1988–2011). One is an atmospheric model inter-comparison (AMIP) type of run forced with observed sea-surface temperature (SST), sea ice, and greenhouse gases (referred to as Exp RSI), and the other is the same as Exp RSI except for the sea ice forcing, which is a repeating climatological annual cycle (referred to as Exp CSI). Results show that Exp RSI produces the observed dominant pattern of Eurasian winter temperatures and their interannual variation better than Exp CSI (correlation difference up to ∼0.3). Exp RSI captures the observed strong relationship between the sea ice concentration near the Barents and Kara seas and the temperature anomaly across Eurasia, including northeastern Asia, which is not well captured in Exp CSI. Lagged atmospheric responses to sea ice retreat are examined using observations to understand atmospheric processes for the Eurasian cooling response including the Arctic temperature increase, sea-level pressure increase, upper-level jet weakening and cold air outbreak toward the mid-latitude. The reproducibility of these lagged responses by Exp RSI is also evaluated. (letter)

The discharge of radionuclides to the Yenisei River has substantially reduced after shutdown of direct cycle reactors at the Mining and Chemical Combine; currently exposure dose rate above water surface and radionuclide concentration in sewage water flows do not exceed the levels set by existing sanitary rules. The results of other protection measures connected with decommissioning of nuclear- and radiation-dangerous facilities and environment restoration activity are considered in the paper. Recently, the workers of the Mining and Chemical Combine, together with specialists from other Russian institutions and with international participation, made significant progress in investigation and monitoring of the radiological impact, primarily in the Yenisei River floodplain and around the 'Severnyi' radwaste disposal site. The inventory of man-made radionuclides in flood-plain deposits of the Yenisei River was assessed and long-term radionuclide transport into the Kara Sea forecasted. New local information on radionuclide pathways to man and environment was the basis for the development of an original dosimetric model. The models of radionuclide migration in the underground liquid radwaste disposal sites have been created and associated human doses predicted. A GIS project has been developed for Yenisei River floodplain contamination. Future work will include development of M and CC ecological geoinformation cadastre and assessments of the impact of radionuclide exposure on the environment, agriculture, fishing, and water quality, as well as identification of necessary rehabilitation measures.

Proposed amendments to the legal proposition on establishment of non-marital paternity from 1855

Full Text Available Proposed amendments to the article 130 of Serbian Civil Code (henceforth: SCC of 1844 regarding establishment of non-marital paternity were scrutinized in this paper. Originally, establishment of non-marital paternity was granted, but with significant restriction that presumed parent could have been declared the father of an illegitimate child only if he had recognized paternity. That is the reason why in 1855 the Supreme Court suggested amendment to the provision concerning determination of paternity. According to proposed modification, evidence that presumed father was on intimate terms with child's mother in the time of conception should have been sufficient for establishment of paternity. As non-marital relationships were condemned in patriarchal Serbian 19th century society, illegitimate children were considered a product of sin and family disgrace. Hence, the Ministry of Justice, the State Council and Prince Aleksandar Karađorđević were not interested in bettering their position by widening possibilities of determination of fatherhood. Subsequently, in 1868 the amendment was passed by which non-marital paternity could not have been established by a court order, subject to certain exceptions (if one raped or abducted a woman, and the time of conception coincided with the time of abduction or rape. Since 1868 paternity could have been determined solely subject to the consent, i.e. recognition of the illegitimate father.

Full Text Available The objective of this study was to determine the nutrient and antioxidant contents of grape seed and pomace oil extracts from the main Turkish wine grape cultivars, Kalecik karas1, Narince, Hasandede and Emir. Dried and powdered seed and pomace materials were extracted with hexane. The results showed that the oil concentration of seeds ranged from 12.35 to 16.00% while in pomace the oil concentration varied from 5.47 to 8.66%. Grape seed and pomace oils were rich in oleic and linoleic acids and the degree of unsaturation in the oils was over 85%. α- tocopherol was the most abundant tocopherol in the oil extracts. Although γ and δ-tocopherols were found with low concentrations, β-tocopherol was not detected in the oil extracts. Oil extracts from pomace in all cultivars gave the highest tocopherol contents compared to the seeds. The contents of total phenolics were higher in pomace oil extracts than seed oil extracts. The highest total phenolic content (392.74 mg/kg was found in the oil extract from Narince pomace compared to the other oil extracts. The refractive indexes of pomace oil extracts ranged from 1.445 to 1.468 while the refractive indexes of the seed oil extracts ranged from 1.460 and 1.466. In conclusion, wine byproducts including the seeds and pomace can be utilized both to get natural antioxidants and to obtain edible vegetable oil.El objetivo de este estudio fue determinar los contenidos de nutrientes y antioxidantes de extractos de aceite de orujo y pepita de uva de los principales cultivares de uva de Turquía, Kalecik karas1, Narince, Hasandede y Emir.

The complex tectonic setting of the eastern Mediterranean is mainly shaped by the interaction between three major plates, Eurasian, African, and Arabian plates, with additional involvement from the smaller Anatolian Scholle. The internal deformation of the Anatolian Scholle is mainly accommodated along NW-striking dextral and NE-striking sinistral faults, which are explained by the Prandtl Cell model by Şengör (1979). Although some of these strike-slip faults, such as Tuzgölü, Ecemiş and Malatya-Ovacık faults, have long been documented, the Nazimiye Fault (NF) is only presented in very recent studies (Kara et al. 2013; Emre et al. 2012). The aim of the study is to understand intra-plate deformation of the Anatolian Scholle, by studying the morphotectonic structures along the NF. The study area located close to the eastern boundary of Anatolia, roughly on the wedge that is delimited by the North and East Anatolian shear zones and the Malatya-Ovacık Fault Zone. After the preliminary remote sensing analyses and field observations, I mapped the locations of the different terrace treads along the Pülümür River, which is strongly deflected by the activity of the NF. This dextral strike-slip fault, is not only characterized with the deformation of the Pülümür River, but also it shows many beheaded streams, pressure ridges, hot springs and travertines along its course. I sampled one of the alluvial fans for cosmogenic dating at the eastern section of the NF, where about 20 m of dextral offset was measured at the margins of the incised stream. Moreover, additional sampling was performed from different terrace levels along the Pülümür River, in order not only to estimate the min. horizontal rate, but also to quantify the vertical deformation. Moreover, I applied morphometric indices to understand the tectonic control on the local morphology along the NF. Transverse Topographic Symmetry Factor was used to show the relative degree of tectonic activity along the

In a course of work to improve anti-oxidative property and strength of sheets of carbonic composite materials with resins, and further to produce those sheets in an industrial scale, it was tried to prepare two types of 0.4 {approximately} 0.6 m thickness SiC / C composite sheets by heat treatment of two green sheets polycarbosilane ( PCS ) / fran resin / binder type and PCS / (phenol-formaldehyde resin / binder type ) at temperature of 1200 {approximately} 1400{degree}C in an atmosphere of nitrogen. The sheets thus made were subjected to SEM observation, X-ray diffraction, measurement of density and electric resistance, and to tests on weight loss by heating and on bending. The texture of them were as tight as that of their resin carbon ( glassy carbon ). The structural feature is formation of amorphous SiO{sub 2} as a secondary product, This indicates that Si in PCS reacts with oxygen in resin during pyrolysis. The bending strength and anti-oxidative property depend on the SiC content from PCS and that the mixing effect of SiC on them are feasible when a mixing ratio of PCS / resin is higher than (2/1). 13 ref., 7 figs., 2 tabs.

A discussion was given on value of participation of an IPP as seen from an electric power system operation plan prepared by utilities. In the discussion, evaluation was made using as the breakeven cost of IPP power purchase prices the difference in power generation cost between electric power systems in which an IPP is participating and not participating, or in other words, the reduced portion of the power generation cost. As a result of the discussion, the following matters were indicated: in the case where an utility company expands its capacity by installing a coal-fired thermal power plant which is lower in operation cost, to deal with increase in power demand, the breakeven cost could be an avoidable cost for the utility company; if the expansion by installing a coal-fired thermal plant is not possible, the breakeven cost for a base type IPP would rise; the breakeven cost for a peak type IPP would be higher than for the base type IPP because the breakeven cost can serve to cut the peak for generators owned by the utility company; and participation of an IPP to power sources in remote areas would provide a large effect to reduce power transmission loss in an entire system, thereby increasing the breakeven cost. 1 ref., 9 figs., 3 tabs.

Researches were conducted with a view to organizing projects for developing intelligent fibers, equipped with environmental friendliness and amenity without being deprived of their original properties as structural and clothing materials, the ultimate goal of the effort being the creation of harbingers of next-generation fibers which would contribute to the advance of industries related to environments, medicine and welfare, and information. What were learned from fiscal 1998 researches are mentioned below. The strength that the general-purpose fibers currently in use exhibit is so small as to be but several percent of what is theoretically predicted for them. Demand will increase a great deal if the actual strength is doubled, for which new technologies have to be developed including those involving super-fiber texture control. For providing the fiber with such functions as environment-friendliness, amenity, etc., it is necessary to develop phasal structure control technologies with regard to fiber morphology, surface texture, etc. For success in practical application in the future of such super-fiber materials, each specimen needs to be manufactured in the order of kilogram by way of trial. Moreover, fiber evaluation techniques have to be developed in the three domains of software, hardware, and interface. (NEDO)

By ZEV regulation of the California government in 1990, not only the United States but also European countries and Japan are largely interested in replacing gasoline car by electric vehicle. Electric utilities expect that the electric vehicle improves the difference between the daytime and nighttime of a recent demand as a new market of electric power demand. There are some reports that indicates on the danger which generates the new peaks as the electric vehicles spread through the market in charging start hour. As the countermeasure for avoiding this problem, the authors propose that 1) inverse load flow by discharging of the contract private use EV is carried out as an energy shift in daytime, 2) the regional charging time shift method is introduced in the midnight charging time zone, in this paper. Therefore, the energy actual consumption of the automobile was investigated, and future demand was predicted by the mathematical consumption modeling. Especially, it is described a strategy of optimum introduction on scheme of effective electric vehicle for energy shift in section 2.2. And authors point out the necessity of market regulation for EV. 14 refs., 10 figs., 1 tab.

The research and development efforts aim to use more magnesium alloys of high performance aboard passenger cars. In the research and development of magnesium alloys for die-casting, studies are conducted about 14 kinds of alloys with their heat treatment properties improved, all based on an Mg-9%Zn-4.5%Al-0.6%Ca alloy which is expected to be excellent in resistance to heat and corrosion. In the development of forging-oriented high-strength magnesium alloys to be excellent in withstanding a hot working process, tractive characteristics superior to those of a forged 6061 aluminum material are obtained from an annealed ZK31 alloy. In the development of a high-performance heat-resistant magnesium alloy die-casting technology, it is found that an injection speed higher than that used for the existing alloys is necessary to achieve a product quality which is sound. This is true for all heat-resistant alloys except the ZAC series. Furthermore, technologies are developed which involve the forging of high-performance magnesium alloys, high-precision high-speed wet cutting, surface reforming of the environmentally friendly type, laser beam welding, etc. (NEDO)

In promoting international collaboration research project, coordination of the patent system of each country which participants to the project belong to has broad implications in concluding the contract for the project. For example, in Japan, 100% of the patent belongs to the government for contrast or collaboration project with the government. While, in the USA, the patent developed by the private company belongs to the private company even for the contrast project. In Japan, the shared patent can not be transferred to the third party or implemented without agreement with the partner. While, in the USA, the shared patent can be transferred to the third party or implemented without agreement with the partner. Due to such a difference, some projects can not be established by ill coordination of intellectual property even when the meaning of the projects is well understood. In this survey, was investigated the outline of patent systems of major countries to study about what should well balanced treatment of intellectual property in international collaboration research project be in the future. 4 figs., 8 tabs.

Kholmiansky, Mikhail; Anokhin, Vladimir

2013-04-01

Hydrocarbon deposits at the Arctic shelf of Russia are a source of jet dispersion of heavy metals that forms haloes in sediments and in the bottom layer of sea water. The intensity of the haloes and their spatial position are jointly determined by geological structure of their source and the environment, i.e., hydrocarbon deposits in host rocks, seafloor lithodynamics and oceanographic factors. Based on theoretical works of Kholmyansky and Putikov (2000; 2006; 2008), an application of electrochemical modification of electric prospecting for offshore hydrocarbon exploration and detailed survey of the morphology of deposits was developed. Specialized equipment was developed for studies of electrochemical features of bottom water layer. With this equipment one can detect ion anomalies in water and determine the type of deposit as gas, gas hydrate, gas condensate or oil. At operation, the unit with equipment is towed underwater off the stern of research vessel. Type and configuration of deposits are determined based on occurrence of trace heavy metals detected by ion-selective electrodes. The proposed method was applied to study a few hydrocarbon fields in Barents and Kara seas in 2001 -2012 including Shtokman, Medyn, Polyarnoe, Prirazlomnoye and others. The results allowed us to trace the margins of the deposits in more detail, and geochemical data, in addition, showed the type of deposits. In general, the method has proven efficient and applicable to a wide range of hydrocarbon deposits.

The main objective of the project has been to establish and test a process for treatment of residues from the semidry (and dry) lime injection based APC processes at MSWIs, which will ensure that the residues can be managed in an environmentally safe manner. In pursuit of this goal, the following activities have been carried out: Performance of pilot scale extractions (approximately 50 kg of residue per batch) at the KARA MSWI in Roskilde of semidry APC system residues in order to establish and optimize process conditions. The optimization includes consideration of the possibilities for subsequent treatment/stabilization of the extracted solid phase as well as the possibility of treatment and safe discharge/utilization of the extract; Performance of chemical characterization, hydrogeochemical model calculations and experimental work in order to improve the understanding of the mechanisms and factors which for several contaminants control the equilibrium between the solid and liquid phases, both in the short and the long germ, and to use this information to obtain an environmentally acceptable method for stabilization/treatment of the extracted residues while at the same time minimizing the necessary amount of additives; production of treated residues and performance of leaching tests on these to assess and demonstrate the effectiveness of the entire process (extraction + stabilization/treatment); Evaluation of the technical, economical and environmental consequences of full scale implementation of the process.

Water Mass Classification on a Highly Variable Arctic Shelf Region: Origin of Laptev Sea Water Masses and Implications for the Nutrient Budget

Science.gov (United States)

Bauch, D.; Cherniavskaia, E.

2018-03-01

Large gradients and inter annual variations on the Laptev Sea shelf prevent the use of uniform property ranges for a classification of major water masses. The central Laptev Sea is dominated by predominantly marine waters, locally formed polynya waters and riverine summer surface waters. Marine waters enter the central Laptev Sea from the northwestern Laptev Sea shelf and originate from the Kara Sea or the Arctic Ocean halocline. Local polynya waters are formed in the Laptev Sea coastal polynyas. Riverine summer surface waters are formed from Lena river discharge and local melt. We use a principal component analysis (PCA) in order to assess the distribution and importance of water masses within the Laptev Sea. This mathematical method is applied to hydro-chemical summer data sets from the Laptev Sea from five years and allows to define water types based on objective and statistically significant criteria. We argue that the PCA-derived water types are consistent with the Laptev Sea hydrography and indeed represent the major water masses on the central Laptev Sea shelf. Budgets estimated for the thus defined major Laptev Sea water masses indicate that freshwater inflow from the western Laptev Sea is about half or in the same order of magnitude as freshwater stored in locally formed polynya waters. Imported water dominates the nutrient budget in the central Laptev Sea; and only in years with enhanced local polynya activity is the nutrient budget of the locally formed water in the same order as imported nutrients.

Northwest Russia and the Dumping of Radioactive Waste: The London Convention Implemented

The `Polar Oceans and the Law of the Sea Project`, POLOS, is a three-year international research project in international law and international relations. This report is one of the publications under POLOS. The subject is the Soviet dumping of radioactive waste in the Barents and Kara Seas. The most intensely radioactive waste is a number of submarine reactors still containing high-level spent fuel. Some of this dumping violated Soviet commitments to the 1972 London Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, and this is the starting point of the report. The discussion focuses on how international regimes may affect the domestic implementation in member states, that is, how international agreements can be converted into behavioural adaptation on the part of target groups. Soviet and later Russian management of nuclear waste in the north has been significantly influenced by regulations and programmes generated under international dumping instruments. These international programmes have been supported by the active participation of the Navy itself in the belief that they would lead to transfer of technology and financial resources to Russia from the West. Inspection of military nuclear waste management is largely left to the Northern Fleet. As for monitoring, measurements were for a long time not taken near the dumping sites. As for regulations, the Northern Fleet continued dumping long into the 1990s without permission. Regarding compliance stimulation, foreign support has helped the Northern Fleet avoid dumping. 113 refs.

Full Text Available In the 16th–17th centuries, West European navigators made numerous but mostly unsuccessful efforts to open a new way, i.e. the North-East Passage, to China and India. Among three possible routes of that time the basic one ran through straits of the Vaigach Island but it was almost impassable due to heavy ice situation. At the same time Russian merchants regularly went on their ships from Pomorie to Siberian river mouths, and in the opposite direction, though they did also meet complicated ice situations. Russian navigator and geographer F.P. Litke (1797–1882 noticed that the ice situation in one or another region of the Barents Sea seriously changed from year to year. Russian navigation started in the Russian Pomorie (littoral region of the Russian Arctic not earlier than at end of June – beginning of July but Europeans knew nothing about this. Because of this, their ships came to the Vaigach region either earlier or later of the time when it was possible to go through the straits. Most often, they came here in the first half- and mid-August. Thus, western sailors could not get this quite narrow navigation «window» of pomors (Russian navigators. And if sometimes (rather rarely they could catch the right time and go through the strait Yugorski Shar they met extremely heavy ice situation in the Kara Sea. Perhaps for this reason, almost all European expeditions of that time failed.

This article provides an assessment of the impact of global fallout on (137)Cs contamination in the bottom sediments of Kara Sea. The erosiveness of 10th-level river basins was estimated by landscape-geochemical and geomorphological characteristics. All 10th-level basins (n=154) were separated into three groups: mountain, mountain-lowland and plain. Four different types of basins were identified depending on the geochemical conditions of the migration of radiocaesium in the plain and mountain-lowland. Classifications of types were carried out using the geographic information systems-based approach. The Ob River's macroarena covers 3.5 million km(2). Internal drainage basins cover 23 % of the macroarena and accumulate whole radiocaesium from the global fallout. The remaining territory is transitional for the (137)Cs. The field research works performed in the three plain first-level basins allow one to estimate the radiocaesium run-off. The calculations show that 7 % of (137)Cs was removed from the first-level basin in arable land. Accumulation of radiocaesium in the first-level basin under undisturbed forest is 99.8 %. The research shows that (137)Cs transfer from the humid basins is in the range of 6.9-25.5 TBq and for semi-humid basins 5.6-285.5 TBq. The areas of these basins cover 40 and 8 % of the Ob River's macroarena, respectively. Drainage lakes and reservoir drainage basins make up 22 % of the macroarena. Mountainous and semi-arid drainage basins cover 7 % of the macroarena.

As benzyl alcohol (BA), which is one of the simplest alcohol having aromatic ring, has been used widely for the fields related to soap, perfume and chemicals industry, its usage has not always been so much because of its expensiveness. Authors developed previously a new process technique to produce cheaper and higher purity BA not through chlorination process using toluene as its raw materials. The BA can be obtained by hydrogenating methyl benzoate (MB) at a dispersion babble tower using cupper-chromium type powder catalyst in mixed solvent of methanol and toluene. The catalyst becomes much fine particles after the reaction. In this study, it is examined to separate MB hydrogenation reaction solution obtained by electrostatic settling into solid and liquid phases as an aim to improve the BA production process. Rate of electrostatic settling does not depend upon solid concentration, slurry forming conditions, electrode materials, specific resistance of slurry layer and others, but is in proportion to electric field intensity. Furthermore, process of the electrostatic settling is expressed by an equation. 9 refs., 9 figs., 3 tabs.

Viscoelasticity of gel films prepared from solvent-soluble constituents without ash of coal using the mixed solvent of carbon disulfide and N-methyl-2-pyrrolidinone (CS2-NMP) was measured to study the network structure of the constituents. In experiment, Upper Freeport coal and Zao Zhuang coal were used as specimens. Viscoelasticity of various gels with different weight fractions of solvent was measured by creep measurement under a fixed load and stress-strain analysis under variable loads. In the 2nd and 3rd creep measurements, although no large changes in elastic strain and viscoelastic strain were found, viscous strain gradually decreased with an increase in viscosity. In the case of small weight fraction of solvent, small viscous strain and viscoelastic strain were found, while slightly large elastic strain was found. It was thus suggested that this elastic strain is derived from not only physical cross-linked networks by coal-solvent interaction but also those by coal-coal interaction in polymer chains of coal itself. 9 refs., 4 figs., 1 tab.

HTML as electronic format for Internet is unfortunately insufficient to describe the logical structure of NEDO research reports because of HTML's restricted description. Thus, XML which is being watched because of its possible definition of original tags was studied in place of HTML. As a result, because at present preparation of standards on XML and a compatibility for implementation of standards are insufficient, it was concluded that construction of the electronic document system for NEDO research reports is still too early. However, since adoption of XML as document format is important from the viewpoint of a property succession on Internet, preparation of the XML format file of NEDO research reports is essential.

Marine radioecology. Annual report 1996. Project plan 1997

International Nuclear Information System (INIS)

1997-06-01

The project plan for the EKO-1 project states that 'the main aim of the EKO-1 project is to enable faster and better assessments to be made of the effects of releases of radionuclides into the marine environment'. To meet this goal the main parts of the project were defined as follows: Model work - Identifying parameters of main interest including estimating and validating the values of these parameters; Research - Field studies, environments typical for various Nordic regions, environments with special physical or chemical characteristics. Laboratory studies; Dissemination of information - Seminars, reports, articles. During the project period emphasis has also been put on quality issues concerning sampling and analysis. The project work has progressed in accordance with project plans in 1996 and within the set budget. In modelling a parameter sensitivity analysis was carried out for a radiological assessment model used for the prediction of doses to man from dumping of radioactive waste in the Kara Sea. Doses to man were found to be generally dominated by contributions from long-lived transuranic radionuclides (plutonium and americium) which associate readily with sediments. Sediment related processes and parameters show therefore high sensitivities, especially at long distances (e.g. Barents Sea). Within the EKO-1 project there has been emphasis on encouraging the Nordic aspect of sediment research in spite of the limitations set by nationally run sampling projects. The EKO-1 project has managed this by e.g.: Organizing exchange of samples for analysis links with the EKO-2.3 project ('Limnic systems'). (EG) 52 refs

Environmental security benefits arising from Russian/Norwegian/US cooperation in the high Arctic

International Nuclear Information System (INIS)

Dyer, R.S.

1997-01-01

Past practices associated with the civilian and military use of nuclear power in NW Russia present large environmental security risks of international concern. These risks arise from a variety of practices associated with weapons production, testing, power production and waste management. The threats presented by these activities are multimedia in nature, span political boundaries and cannot be simply or inexpensively remediated. Today, cooperative efforts are being undertaken to improve environmental security by remediating existing and potential emission sources. Initial efforts focused on the upgrade and expansion of the Murmansk Low-level Liquid Waste Treatment Facility, Murmansk, Russia. This facility handles wastes generated during the decommissioning of Russian Nuclear Navy submarines and from the operation of the Russian commercial nuclear-powered icebreaker fleet. This upgraded facility is now being constructed and is expected to be completed by March 1998. Completion of this facility will result in the cessation of any future dumping of liquid radioactive wastes into the Barents and Kara Seas. Another large environmental security risk is the LEPSE. The LEPSE is a ship docked in Murmansk, Russia, that contains ∼650 spent fuel elements as well as other solid and liquid wastes from Russian nuclear vessels. International efforts are now being mounted to remove the spent and damaged fuel from this ship, including the safe removal and storage/disposal of the fuel elements. This paper will summarize the environmental security problems presented by these different sources and the likely environmental security benefits associated with their remediation. 5 refs., 1 fig., 1 tab

Pre-LGM Northern Hemisphere ice sheet topography

Full Text Available We here reconstruct the paleotopography of Northern Hemisphere ice sheets during the glacial maxima of marine isotope stages (MIS 5b and 4.We employ a combined approach, blending geologically based reconstruction and numerical modeling, to arrive at probable ice sheet extents and topographies for each of these two time slices. For a physically based 3-D calculation based on geologically derived 2-D constraints, we use the University of Maine Ice Sheet Model (UMISM to calculate ice sheet thickness and topography. The approach and ice sheet modeling strategy is designed to provide robust data sets of sufficient resolution for atmospheric circulation experiments for these previously elusive time periods. Two tunable parameters, a temperature scaling function applied to a spliced Vostok–GRIP record, and spatial adjustment of the climatic pole position, were employed iteratively to achieve a good fit to geological constraints where such were available. The model credibly reproduces the first-order pattern of size and location of geologically indicated ice sheets during marine isotope stages (MIS 5b (86.2 kyr model age and 4 (64 kyr model age. From the interglacial state of two north–south obstacles to atmospheric circulation (Rocky Mountains and Greenland, by MIS 5b the emergence of combined Quebec–central Arctic and Scandinavian–Barents-Kara ice sheets had increased the number of such highland obstacles to four. The number of major ice sheets remained constant through MIS 4, but the merging of the Cordilleran and the proto-Laurentide Ice Sheet produced a single continent-wide North American ice sheet at the LGM.

Full Text Available In order to assess the strength of the water vapour feedback within Arctic climate change, 15 years of the total column-integrated density of water vapour (TCWV from the moderate resolution imaging spectrometer (MODIS are analysed. Arctic TCWV distribution, trends, and anomalies for the 2001–2015 period, broken down into seasons and months, are analysed. Enhanced local spring TCWV trends above the terrestrial Arctic regions are discussed in relation to land snow cover and vegetation changes. Upward TCWV trends above the oceanic areas are discussed in lien with sea ice extent and sea surface temperature changes. Increased winter TCWV (up to 40% south of the Svalbard archipelago are observed; these trends are probably driven by a local warming and sea ice extent decline. Similarly, the Barents/Kara regions underwent wet trends (up to 40%, also associated with winter/fall local sea ice loss. Positive late summer TCWV trends above the western Greenland and Beaufort seas (about 20% result from enhanced upper ocean warming and thereby a local coastal decline in ice extent. The Mackenzie and Siberia enhanced TCWV trends (about 25% during spring are found to be associated with coincident decreased snow cover and increased vegetation, as a result of the earlier melt onset. Results show drier summers in the Eurasia and western Alaska regions, thought to be affected by changes in albedo from changing vegetation. Other TCWV anomalies are also presented and discussed in relation to the dramatic decline in sea ice extent and the exceptional rise in sea surface temperature.

The effect of Arctic sea-ice extent on the absorbed (net solar flux at the surface, based on ISCCP-D2 cloud data for 1983–2007

Full Text Available We estimate the effect of the Arctic sea ice on the absorbed (net solar flux using a radiative transfer model. Ice and cloud input data to the model come from satellite observations, processed by the International Satellite Cloud Climatology Project (ISCCP and span the period July 1983–June 2007. The sea-ice effect on the solar radiation fluctuates seasonally with the solar flux and decreases interannually in synchronisation with the decreasing sea-ice extent. A disappearance of the Arctic ice cap during the sunlit period of the year would radically reduce the local albedo and cause an annually averaged 19.7 W m⁻² increase in absorbed solar flux at the Arctic Ocean surface, or equivalently an annually averaged 0.55 W m⁻² increase on the planetary scale. In the clear-sky scenario these numbers increase to 34.9 and 0.97 W m⁻², respectively. A meltdown only in September, with all other months unaffected, increases the Arctic annually averaged solar absorption by 0.32 W m⁻². We examined the net solar flux trends for the Arctic Ocean and found that the areas absorbing the solar flux more rapidly are the North Chukchi and Kara Seas, Baffin and Hudson Bays, and Davis Strait. The sensitivity of the Arctic absorbed solar flux on sea-ice extent and cloud amount was assessed. Although sea ice and cloud affect jointly the solar flux, we found little evidence of strong non-linearities.

Impacts on the marine environment in the case of a hypothetical accident involving the recovery of the dumped Russian submarine K-27, based on dispersion of 137Cs.

There is increasing concern regarding the issue of dumped nuclear waste in the Arctic Seas and in particular dumped objects with Spent Nuclear Fuel (SNF). Amongst dumped objects in the Arctic, the dumped Russian submarine K-27 has received great attention as it contains two reactors with highly enriched fuel and lies at a depth of about 30 m under water. To address these concerns a health and environmental impact assessment has been undertaken. Marine dispersion of potentially released radionuclides as a consequence of different hypothetical accident scenarios was modelled using the model NAOSIM. The outputs from the dispersion modelling have been used as inputs to food-chain transfer and environmental dosimetry models. The annual effective doses for subsistence fishing communities of the Barents-Kara seas region do not exceed 0.6 mSv for hypothetical accidents located at Stepovogo fjord or the Barents Sea. For high rate consumers of fish in Norway, following a potential accident at the Gremikha Bay, annual effects doses would be at around 0.15 mSv. Accumulated doses (over 90 days) for various organisms and for all release scenarios considered were never in excess of 150 μGy. The levels of 137 Cs derived for marine organism in areas close to Norway were not values that would likely cause concern from a regulatory perspective although for subsistence fishing communities close to the considered accident locations, it is not inconceivable that some restrictions on fishing etc. would need to be introduced.

The spatial and temporal distributions of the anthropogenic radionuclides 137 Cs and 90 Sr, originating from nuclear bomb testing, the Sellafield reprocessing plant in the Irish Sea (UK), and from the Ob and Yenisey river discharges to the Arctic Ocean, have been simulated using the global version of the Miami Isopycnic Coordinate Ocean Model (MICOM). The physical model is forced with daily atmospheric re-analysis fields for the period of 1948-1999. Comparison of the temporal evolution of the observed and the simulated concentrations of 90 Sr has been performed in the Kara Sea. The relative contributions of the different sources on the temporal and spatial distributions of the surface 90 Sr are quantified over the simulated period. It follows that the Ob river discharge dominated the surface 90 Sr over most of the Arctic Ocean and along the eastern and western coasts of Greenland before 1960. During the period of 1980-1990, the atmospheric fallout and the Ob river discharge were equally important for the 90 Sr distribution in the Arctic Ocean. Furthermore, an attempt has been made to explore the possible dispersion of accidental released 90 Sr from the Ob and Yenisey rivers under a global warming scenario (2 x CO 2 ). The difference between the present-day and the global warming scenario runs indicates that more of the released 90 Sr from the Ob and Yenisey rivers is confined to the Arctic Ocean in the global warming run, particularly in the near coastal, non-European part of the Arctic Ocean.

The populations of Eurasian lynx in Anatolia are as fragmented as the European populations. Although the origins of and the connections between the European lynx populations have been elucidated, there have been no genetic studies on the lynx populations in Turkey. The lack of genetic and evolutionary information about lynx in Anatolia, which is considered to be a biodiversity hotspot, makes it difficult to track the migration routes during the Quaternary. In this study, we present the genetic characteristics of two isolated lynx populations in Southwest Taurus Mountains and the Turkish Caucasus as well as two individuals from Erzincan area. DNA purified from the ecological scat samples collected from Çığlıkara Nature Reserve in Elmalı-Antalya and Allahuekber Mountains in Sarıkamış-Kars, as well as two roadkill samples from Erzincan, has been analysed for phylogenetic markers such as the mitochondrial DNA control region and cytochrome b. The DNA sequences were compared with haplotypes previously detected in populations from Europe and the Caucasus in order to determine the evolutionary relationships of the populations. This study compares the current genetic structure of some of the Turkish lynx populations to the other lynx genetic data, mostly carried out with museum samples around the world. Three haplotypes were found in three different regions of Anatolia. The Northeast and Southwest populations harbour genetically distinct haplotypes, the latter one, a new haplotype: H13-TR is the only phylogenetic connection to the critically endangered Balkan lynx yet to be described.

Hydrogeochemical and stream sediment detailed geochemical survey for Edgemont, South Dakota; Wyoming

International Nuclear Information System (INIS)

1981-01-01

An area on the Long Mountain Structure Zone was chosen for examination of hydrogeochemical data. The data suggest the presence of a hydrogeochemical boundary approximately 5 to 7 km (3-1/2 to 4-1/2 mi) downdip of exposed mines and prospects in the Inyan Kara Group. Based on studies by Gatt, et al (1974) the hydrogeochemical boundary is interpreted to represent a zone of ion exchange favorable for precipitation of uranium. Updip of the boundary, the groundwater is of a calcium sulfate type. Uranium concentrations range from <0.2 to 32 ppB (mean = 13 ppB), calcium concentrations range from 85 to 320 ppB (mean = 158 ppB), and sulfate concentrations range from 600 to 1800 ppM (mean = 708 ppM). Sodium concentrations range from 43 to 363 ppM (mean = 168 ppM) and total alkalinity values range from 130 to 330 ppM (mean = 244 ppM). Downdip of the boundary, the groundwater is of a sodium bicarbonate type. Uranium concentrations range from < 0.2 to 0.54 ppB (mean = .28 ppB), calcium concentrations range from 1.0 to 45 ppB (mean = 8.4 ppB), and sulfate concentrations range from 41 to 1400 ppM (mean = 266 ppM). Sodium concentrations range from 176 to 744 ppM (mean = 296 ppM) and total alkalinity values range from 140 to 920 ppM (mean = 596 ppM). The maximum uranium value observed (32 ppB) occurs near the hydrogeochemical boundary

Dissolved lignin phenols, chromophoric dissolved organic matter (CDOM) absorption, and fluorescence were analyzed along cross-slope mooring locations in the Barents, Laptev, and East Siberian Seas to gain a better understanding of terrigenous dissolved organic carbon (tDOC) dynamics in Arctic shelf seas and the Arctic Ocean. A gradient of river water and tDOC was observed along the continental shelf eastward into the East Siberian Sea. Correlations of carbon-normalized yields of lignin-derived phenols supplied by Siberian rivers with river water fractions and known water residence times yielded in situ decay constants of 0.18-0.58 per year. Calculations showed about 50% of annual tDOC discharged by Siberian rivers was mineralized in estuaries and on the Eurasian shelves per year indicating extensive removal of tDOC. Bioassay experiments and in situ decay constants indicated a reactivity continuum for tDOC. CDOM parameters and acid/aldehyde ratios of vanillyl (V) and syringyl (S) lignin phenols showed biomineralization was the dominant mechanism for the removal of tDOC. Characteristic ratios of p-hydroxy (P), S, and V phenols (P/V, S/V) also identified shelf regions in the Kara Sea and regions along the Western Laptev Sea shelf where formation of Low Salinity Halocline Waters (LSHW) and Lower Halocline Water (LHW) occurred. The efficient removal of tDOC demonstrates the importance of Eurasian margins as sinks of tDOC derived from the large Siberian Rivers and confirms tDOC mineralization has a major impact on nutrients budgets, air-sea CO2 exchange, and acidification in the Siberian Shelf Seas.

Analysis of Arctic sea ice extents derived from satellite passive-microwave data for the 28 years, 1979-2006 yields an overall negative trend of -45,100 +/- 4,600 km2/yr (-3.7 +/- 0.4%/decade) in the yearly averages, with negative ice-extent trends also occurring for each of the four seasons and each of the 12 months. For the yearly averages the largest decreases occur in the Kara and Barents Seas and the Arctic Ocean, with linear least squares slopes of -10,600 +/- 2,800 km2/yr (-7.4 +/- 2.0%/decade) and -10,100 +/- 2,200 km2/yr (-1.5 +/- 0.3%/decade), respectively, followed by Baffin Bay/Labrador Sea, with a slope of -8,000 +/- 2,000 km2/yr) -9.0 +/- 2.3%/decade), the Greenland Sea, with a slope of -7,000 +/- 1,400 km2/yr (-9.3 +/- 1.9%/decade), and Hudson Bay, with a slope of -4,500 +/- 900 km2/yr (-5.3 +/- 1.1%/decade). These are all statistically significant decreases at a 99% confidence level. The Seas of Okhotsk and Japan also have a statistically significant ice decrease, although at a 95% confidence level, and the three remaining regions, the Bering Sea, Canadian Archipelago, and Gulf of St. Lawrence, have negative slopes that are not statistically significant. The 28-year trends in ice areas for the Northern Hemisphere total are also statistically significant and negative in each season, each month, and for the yearly averages.

Fungal pathogens are the cause of the most common diseases in grapevine and among them powdery mildew represents a major focus for disease management. Different strategies for introgression of resistance in grapevine are currently undertaken in breeding programs. For example, introgression of several resistance genes (R) from different sources for making it more durable and also strengthening the plant defense response. Taking this into account, we cross-pollinated P09-105/34, a grapevine plant carrying both RUN1 and REN1 pyramided loci of resistance to Erysiphe necator inherited from a pseudo-backcrossing scheme with Muscadinia rotundifolia and Vitis vinifera ‘Dzhandzhal Kara,’ respectively, with the susceptible commercial table grape cv. ‘Crimson Seedless.’ We developed RUN1REN1 resistant genotypes through conventional breeding and identified them by marker assisted selection. The characterization of defense response showed a highly effective defense mechanism against powdery mildew in these plants. Our results reveal that RUN1REN1 grapevine plants display a robust defense response against E. necator, leading to unsuccessful fungal establishment with low penetration rate and poor hypha development. This resistance mechanism includes reactive oxygen species production, callose accumulation, programmed cell death induction and mainly VvSTS36 and VvPEN1 gene activation. RUN1REN1 plants have a great potential as new table grape cultivars with durable complete resistance to E. necator, and are valuable germplasm to be included in grape breeding programs to continue pyramiding with other sources of resistance to grapevine diseases.

Evaluation of the limit ice thickness for the hull of various Finnish-Swedish ice class vessels navigating in the Russian Arctic

Directory of Open Access Journals (Sweden)

2018-05-01

Full Text Available Selection of suitable ice class for ships operation is an important but not simple task. The increased exploitation of the Polar waters, both seasonal periods and geographical areas, as well as the introduction of new international design standards such as Polar Code, reduces the relevancy of using existing experience as basis for the selection, and new methods and knowledge have to be developed. This paper will analyse what can be the limiting ice thickness for ships navigating in the Russian Arctic and designed according to the Finnish-Swedish ice class rules. The permanent deformations of ice-strengthened shell structures for various ice classes is determined using MT Uikku as the typical size of a vessel navigating in ice. The ice load in various conditions is determined using the ARCDEV data from the winter 1998 as the basic database. By comparing the measured load in various ice conditions with the serviceability limit state of the structures, the limiting ice thickness for various ice classes is determined. The database for maximum loads includes 3-weeks ice load measurements during April 1998 on the Kara Sea mainly by icebreaker assistance. Gumbel 1 distribution is fitted on the measured 20 min maximum values and the data is divided into various classes using ship speed, ice thickness and ice concentration as the main parameters. Results encouragingly show that present designs are safer than assumed in the Polar Code suggesting that assisted operation in Arctic conditions is feasible in rougher conditions than indicated in the Polar Code.

This paper reports the activities of the coal type committee in fiscal 1992, and summarizes the main technological achievements. In the Chinese coal liquefaction test, fiscal 1991 has performed liquefaction tests on Fushun coal by using a small continuous testing facility (0.1 t/d) at the Coal Chemistry Research Institute in Beijing. Fiscal 1992 has completed the liquefaction tests on Shengli coal. In October, a liquefaction test was carried out by using Tianzhu coal according to the NEDOL process. This paper reports the result of the liquefaction test on the Shengli coal, and the result of the analysis on the Fushun coal liquefied oil. The coal type selection and investigation having been performed to date reveals close correlation among the maceral composition of coal, coal rank and liquefied oil yield. Coals having good reactivity and suitable for liquefaction are generally suitable also for gasification. In the pretreatment of coal as a gasification material for hydrogen manufacture, a test was performed by using A heavy oil and tar sand bitumen plus A heavy oil as the granulating agents. With Montana coal, the highest de-ashing rate was achieved when the oil was added at 35% by weight. Both of the reaction rate and oil yield were improved. A handling test was carried out up to 72.5 degrees C, wherein Tatung coal presented no problems in both of the discharging and sticking tendencies. (NEDO)

The subcommittee held the 1st meeting in September 1955 and the 2nd in March 1996, when fiscal 1995 research plans and research results were introduced and deliberated. In the study for designing a high-dispersion catalyst and the elucidation of the mechanism of activity expression, catalysts of highly dispersed iron supported on the brown coal surface in various ways were compared with each other in terms of liquefaction activity. Furthermore, geometric changes in the iron catalyst during the sulfurizing process were examined using the XRD (X-ray diffraction) and TEM (transient electromagnetic) methods. An improved catalyst was found to achieve a liquefaction yield near the Yallourn coal liquefaction limit in a high boiling solvent system. Concerning the study of coal oil product applications and refining technologies, reports were delivered on research results relating to the problem of blocking to occur during naphtha fraction refining and measures therefor, inhibition of active metal geometric changes during reaction, methods for separating hetero-compounds from coal oil and application thereof, and so forth.

A coal type research project is started under which data concerning the coal resources that Japan can make use of are to be gathered, which are necessary for determining their fitness-for-use in a coal liquefaction or gasification process, and the gathered data are to be compiled into files which are easy to use. As for the buildup of a computer-aided data bank, since the number of coal types is not yet large, only part of the data is taken into consideration this fiscal year. In the study of compiling the data into files, it is decided that the files be divided into two categories, one for grasping the status of the development project as a whole and the other for defining the positions of the individual coal specimens. Provided in the former are outlines covering the name of coal mine or project, location, entrepreneur, states of the mining area and geology, state of production, infrastructure-related matters, etc. Described in the latter are the details that enable the identification of given specimens such as the coal bed or coal brand, location and method of collection, collector, date, amount of the specimen, method of treatment, etc. (NEDO)

In a servo PD (positive displacement) flowmeter for oil, a differential pressure transmitter detects difference in pressure between the PD flowmeter input and output ports and a rotor is driven by a servo motor so that the pressure difference between before and after the PD flowmeter rotor will be zero. The design enables high-accuracy measurement across a wide range of flow rates and is not easily affected by the surrounding physical conditions such as viscosity and density. For the development of such a flowmeter, it is necessary to develop a rotor that rotates smoothly free of locking in a steady and uniform flow, to build a visualized model that enables the analysis of flow inside the flowmeter which in turn will enable the determination of optimum differential pressure detecting ports, and to connect a newly developed servo mechanism to the thus determined ports. As the result of the research, a servo PD flowmeter is developed, which is a 50mm diameter prototype employing the Invoflex tooth form which is the waveform for a rotor suitable for a high performance flowmeter. Placed in a generally used oil flow calibration liquid, which is gasoline, kerosene, or the like, it covers a flow rate range of 1:10 and reads with an accuracy of {+-}0.1%. It remains stable in performance and suffers but a little change with the passage of time. (NEDO)

Coal ash from the fluidized bed boiler is evaluated for its properties as is, as solidified or granulated, and as the roadbed material. The coal ash tested in the experiment is a mixture of ash from the fluidized bed boiler bottom, ash from the cyclone separator, and ash from the bag filter. In the manufacture of solid or granulated bodies, coal ashes are kneaded in water whose amount puts the mixture near the plasticization limit, are pressed in a low-pressure press and made into solid bodies by a 15-hour curing in 60degC saturated steam, and the solid bodies are crushed into solid granules. A content release test is conducted about the release of dangerous substances, and road paving experiments are conducted to learn the workability and serviceability of the granulated material as a road paving material. A study of the experimental results discloses what is mentioned below. Coal ash containing 10-20vol% of CaO and 15vol% or less of unburnt carbon turns into a high-strength solid after curing in saturated steam whose temperature is not higher than 60degC. The granulated solid satisfies the standards that an upper subbase material is expected to satisfy. It also meets the environmental standards in a release content test for soil set forth by Environment Agency notification No.46. 8 refs., 8 figs., 4 tabs.

This paper describes an education and training system placing its emphasis on human interfaces. The paper indicates that the currently used education and training systems lack training functions to cultivate knowledge-based judgment abilities that can find adequate solutions to events that have not been experienced previously; such judgments require deep understanding on the objects; and this training requires a system to aid the comprehension based on knowledges in the realm of recognition science for the 'human understanding'. Next, a pedagogical interface is proposed for aiding the comprehension. The paper enumerates functions indispensable for the comprehension including setting the 'loop for representation and examination', aiding the representation to examination loop, aiding roles by others, and realizing interactions through a hypothetical world. Also enumerated as fundamental techniques to structure such interface are information structuring techniques, groupware techniques, and virtual reality techniques. 19 refs., 10 figs.

Technological trends have been compiled on the basis of the agendas of all the six events from the 1st International Conference on Refractories through the UNITECR `95 held in Japan. Although the number of articles presented increased from 52 to 187 during this period, yet there was a remarkable decrease in the number of articles in some fields related to refractories for iron and steel making, the said field involving pig iron melting preparatory treatment and torpedo cars. There is no great change in the number of articles about the MgO-C brick in use for building converters and electric furnaces that are typical kilns, with various countries presenting papers indicating that the brick is the representative of high-performance refractories being used across the world. There is a steady increase in the number of articles related to nonferrous metals, glass, and cement, and attracting attention is the papers concerning incinerators. The number of papers about basic technologies and new testing methods is constant. Attracting attention are papers for example on fine ceramics with its scope of application as refractories spreading, which reflects the technological trends across the world and the circumstances the host countries find themselves under. It is added here that Brazil rich in refractory resources presented many papers at the conference that it hosted. 27 refs., 7 tabs.

Nuclear techniques applied to animal production and health are concentrated in three main fields: Animal nutrition, reproduction and animal health. Isotopic markers, both radioactive (''1''4C, ''5 1 Cr, 32 P and 35 S) and stable ( 15 N), have been used in the development of feeding strategies by understanding the rumen fermentation process, and how protein and other nutrients are utilized to determine a balanced diet for meeting animal requirements for growth, pregnancy and lactation. The simple and easily applicable technology was developed for the preparation of a urea mineral multi nutrient block as a supplement and animal cake for the replacement of concentrate feed used by dairy cattle holders. The model was developed in Yerli Kara Cattle and its cross-breeds to estimate protein requirements of animals. Progesterone immunoassays (RIA/EIA) make it possible to control the reproductive performance of cattle, sheep and goats. A milk progesterone enzyme immunoassay kit known as Reprokon was developed at our Center. The kit has licensed by the Ministry of Agriculture and Rural Affairs. As for animal diseases, especially parasitic infections, nuclear techniques have proved to be of great value, namely in the production of irradiated vaccines against helminitic diseases. The Enzyme Linked Immunosorbent assay (ELISA) diagnostic techniques were used on the diagnosis of babesiosis, a disease which cause great economic loss in livestock in Turkey. Food irradiation is the treatment of raw, semi-processed or processed food or food ingredients with ionizing radiation to achieve a reduction of losses due to insect infestation, germination of root crops, spoilage and deterioration of perishable produce, and/or the control of microorganisms and other organisms that cause food borne diseases

There are currently no actively recruiting prospective clinical trials investigating potential treatments. There are also no US Food and Drug Administration-approved medical treatments for chemotherapy-associated paronychia and no consensus on the best way to treat these common chemotherapy-induced events. Methods: A retrospective review of all cases presenting to a single dermatology private practice from June 2016 to January 2017 identified nine patients with chemotherapy-associated paronychia seeking treatment. Each patient was prescribed a topical solution comprised of 2% povidone–iodine in a dimethylsulfoxide vehicle that was prepared by a licensed compounding pharmacy. Patients were seen at 3 week and 6 week follow-up visits. Results: All 9/9 patients demonstrated complete or partial resolution. The number of nails involved for each patient ranged from 4–12. There were a total of 58 nails affected in the case series, and 44/58 (76% resolved overall. The treatment was well tolerated. Conclusion: The topical povidone–iodine/dimethylsufoxide solution described is very effective in alleviating the signs and symptoms of paronychia associated with chemotherapy. This novel combination warrants further investigation in randomized, controlled trials to further elucidate its clinical utility. Keywords: paronychia, chemotherapy, taxanes, epidermal growth factor receptor inhibitor, povidone–iodine, dimethylsulfoxide

Full Text Available Kara L Raphael, Field F Willingham Division of Digestive Diseases, Department of Medicine, Emory University School of Medicine, Atlanta, GA, USA Abstract: Hereditary pancreatitis (HP is a rare cause of acute, recurrent acute, and chronic pancreatitis. It may present similarly to other causes of acute and chronic pancreatitis, and often there has been a protracted evaluation prior to the diagnosis of HP. Since it was first described in 1952, multiple genetic defects that affect the action of digestive enzymes in the pancreas have been implicated. The most common mutations involve the PRSS1, CFTR, SPINK1, and CTRC genes. New mutations in these genes and previously unrecognized mutations in other genes are being discovered due to the increasing use of next-generation genomic sequencing. While the inheritance pathways of these genetic mutations may be variable and complex, sometimes involving coinheritance of other mutations, the clinical presentation of patients tends to be similar. Interactions with environmental triggers often play a role. Patients tend to present at an early age (prior to the second decade of life and have a significantly increased risk for the development of pancreatic adenocarcinoma. Patients with HP may develop sequelae of chronic pancreatitis such as strictures and fluid collections as well as exocrine and endocrine insufficiency. Management of patients with HP involves avoidance of environmental triggers, surveillance for pancreatic adenocarcinoma, medical therapy for endocrine and exocrine insufficiency, pain management, and endoscopic or surgical treatment for complications. Care for affected patients should be individualized, with an emphasis on early diagnosis and multidisciplinary involvement to develop a comprehensive treatment strategy. Keywords: pancreatic cancer, chronic pancreatitis, idiopathic pancreatitis, pancreatitis, familial pancreatitis, genetic mutations

Full Text Available The article focuses the mythological beliefs of Bashkirs as reflected in historical anthroponymy using as its main source the document entitled Service records of the officers and clerks of the 9th Bashkir Canton as of 1837. The author considers more than 40 000 personal names and surnames of the 18th–19th centuries paying particular attention to those that contain mythologically marked items reflecting the remotest religious beliefs of Bashkirs. The analysis of anthroponymic data reveals the ancient Bashkirs’ views about gods and divine beings of both the pre-Islamic era and the period that followed the adoption of Islam. Specifically, the author investigates into the ancient Bashkirs’ concept of the presiding deity Tengri and provides a comparative analysis of the beliefs relating to the gods Khuday, Allah, kun / koyash ‘sun’, ay ‘moon’, and others. The names retrieved from the studied document enable to reveal the culturally induced connotations of the colour terms ak ‘white’ and kara ‘black’ as parts of anthroponyms. They were associated with the concepts of purity, holiness, strength and courage and sometimes served as a kind of protective charm. The Bashkir anthroponymy reflects some ancient beliefs related to metals. For example, the word altyn ‘gold’ is closely associated with the upper world, that of the sky and the sun. The 18th–19th centuries Bashkir stock of personal names contains a wide range of names associated with totem animals, birds, trees and other plants that were given to children to protect them from sinister forces. It also contains names that reflect the ancient Bashkirs’ beliefs about time and space.

The Arctic Ocean has been greatly affected by climate change. Future predications show an even more drastic reduction of the ice cap which will open new areas for the exploration of natural resources and maritime transportation.Shipping through the Arctic Ocean via the Northern Sea Route (NSR) could save about 40% of the sailing distance from Asia (Yokohama) to Europe (Rotterdam) compared to the traditional route via the Suez Canal. Vilkitsky strait is the narrowest and northest portion of the Northern Sea Route with heaviest traffic between the Taimyr Peninsular and the Severnaya Zemlya archipelago. The preliminary results of sea ice variations are presented by using moderate-resolution imaging spectro radiometer(MODIS) data with 250-m resolution in the Vilkitsky strait during 2009-2012. Temporally, the first rupture on sea ice in Vilkitsky strait usually comes up in April and sea ice completely break into pieces in early June. The strait would be ice-free between August and late September. The frequency of ice floes grows while temperature falls down in October. There are always one or two months suitable for transport. Spatially, Sea ice on Laptev sea side breaks earlier than that of Kara sea side while sea ice in central of strait breaks earlier than in shoreside. The phenomena are directly related with the direction of sea wind and ocean current. In summmary, study on Spatial and temporal patterns in this area is significant for the NSR. An additional research issue to be tackled is to seeking the trends of ice-free duration in the context of global warming. Envisat ASAR data will also be used in this study.

Marine sediments as a sink, and contaminated sediments as a diffuse source of radionuclides

International Nuclear Information System (INIS)

Salbu, B.; Borretzen, P.

1997-01-01

Full text: Marine sediments may act as a sink for radionuclides originating from atmospheric fallout (e.g. Chernobyl accident), for radionuclides in discharges from nuclear installations (e.g. Sellafield, UK) for river transported radionuclides, and radionuclides released from nuclear waste dumped at sea (e.g. fjords at Novaya Zemlya). In order to assess short and long term consequences of radionuclides entering the marine ecosystem, the role of sediments as a relatively permanent sink and the potential for contaminated sediments to act as a diffuse source should be focused. The retention of radionuclides in sediments will depend on the source term, i.e. the physico-chemical forms of radionuclides entering the system and on interactions with various sediment components. Radionuclides associated with particles or aggregating polymers are removed from the water phase by sedimentation, while sorption to surface sediment layers is of relevance for ionic radionuclide species including negatively charged colloids. With time, transformation processes will influence the mobility of radionuclides in sediments. The diffusion into mineral lattices will increase fixation, while the influence of for instance red/ox conditions and bio-erosion may mobilize radionuclides originally fixed in radioactive particles. Thus, information of radionuclides species, surface interactions, transformation processes and kinetics is essential for reducing the uncertainties in marine transfer models. Dynamic model experiments where chemically well defined tracers are added to a sea water-marine sediment system are useful for providing information on time dependent interactions and distribution coefficients. When combined with sequential extraction techniques, information on mobility and rate of fixation is subsequently attained. In the present work experimental results from the Irish Sea and the Kara Sea will be discussed

Before submitting propositions on important technological tasks to be generated in the automobile production line upon application of IT (information technology), a questionnairing is implemented to know the actualities of the line for the purpose of planning a proper merger of IT and the manufacturing technology development capability of the IT accepting site. The questionnaire, aiming at the embodiment of the goals of the projects 'IT related technical tasks relative to its helping human creation of new technologies and enhancement of human ability to make improvement' and 'Technical tasks of developing technical skills into technologies,' asks engineers about the actualities of knowhow at automobile production lines and its development into technologies, about how they take care of what they learned from their predecessors, and about their expectations from and views and opinions toward IT introduction and utilization. It is important to efficiently utilize IT as a means to solve problems involving the knowhow related training on the production line and the handing down of the acquired knowhow to the juniors. Since individual workers' knowhow assumes a certain role at each stage of the automobile production line and since it is necessary to extract the maximum from each worker and to utilize the fruit for improvement on productivity and work efficiency, it is indispensable to efficiently merge the knowhow with IT.

Summarized in this report is the material already distributed concerning the program for modifying the Nakoso 200t/d pilot plant entrained bed coal gasification furnace. The program aims to verify the overall suitability for power generation use of the air-blow pressurized 2-chamber 2-stage flow entrained bed gasification furnace. Although each specific feature of gasification furnace performance is found to be satisfactory, yet a 100% operation and extended continuous operation remain to be accomplished. Slagging is a phenomenon of ash grains in high-temperature gas adhering to and growing on the furnace walls to block up the furnace to eventually disable the furnace from continuous operation. In view of past achievements and test results, it is found that slagging is closely related to the behavior of floating or molten ash and to the transition temperature range. Various slagging measures have been taken for the current gasification furnace, but they prove to be ineffective. Some drastic measures need to be implemented for improvement. Under study using model furnaces and test furnaces are the reduction of slag generation at its source (re-entrained slag), prevention of adhesion (untrapped slag), removal of slag, optimization of gyration in the furnace, modification of slag properties for enhanced discharge, optimization of the transition gas temperature range, and the modification of furnace dimensions.

This paper reports a joint meeting of the coal liquefaction committee and the coal type committee in fiscal 1993. The report is focussed on the coal type selection (the final report) for the coal used in the 150-t/d coal liquefaction pilot plant (PP) among other agenda. Initially the Australian Wandoan coal was scheduled to be selected as the reference coal for the PP operation, but the mine has not gone into operation, hence the schedule was given up. Screening was carried out to select a coal which is commercially produced and exported, and contains ash at 10% by weight or less, sulfur at 1.5% by weight or less, and chlorine at 300 ppm or less. An autoclave and a 0.01-t/d flowing type device were used to evaluate liquefaction performance, whereas the Tanito Harum coal produced in Indonesia, very similar to the Wandoan coal, was selected as a promising candidate. A PSU was used to demonstrate overall operation performance. The coal is an appropriate reference coal as seen from the aspects of liquefied oil yield, nature, operability, and site surveys in Indonesia. Among the actual record of four kinds of PSU coals in the past, the present coal has the oil yield ranked high, has the least liquefaction residues, and is advantageous economically. The oil yield per ton of coal has cleared the PP target of four barrels. The coal has less ash, is easy in solid/liquid separation in the depressurized distillation, and has no problems in operability, excepting the matter of coal supply. (NEDO)

This is a summary primarily of the distributed material. As of December 14, 1995, the 200t/d pilot plant for power generation by entrained bed coal gasification records a total coal gasification operation time of 4,485 hours with an accumulated amount of power generation of 9,227MWh. A large combustor is tested, and it is found that combustion is stable under a 1/4 load with low NOx emissions. The combustor is sufficiently cooled with a small supply of air. Coal ash and coal, supplied in a constant state for an improved heat recovery efficiency in the development of hydrogen-from-coal technology, are heated to a temperature near their melting points. They are then allowed to impinge at a heat transfer plane simulating a gasifier heat recovery section, and a study is made of the mechanism of ash adhesion, molten or semi-molten, to the heat recovery section. The reduction of the heat transfer coefficient due to added grains is 30-50%, and the reduction is small when the heat transfer pipe surface velocity is high or when the carbon concentration in the grains is high. In another effort, utilization of coal-derived gas as town gas is studied. As for yields as indicated by the Curie gas pyrolyzer, the gas yield increases and liquid yield decreases when the reaction temperature is high. Using a small test unit, it is found that a rise in the hydrogen partial pressure increases the production of both gas and liquid. (NEDO)

An energy-saving vision was decided on in Santo-cho region in Hyogo Prefecture, with its outline reported. This town is such that about 80% of the region is mountains, forests and wilderness and that aging is advancing at the rate above that of Hyogo Prefecture or the national average. Nearly entire energy of the town is dependent on the supply from outside. The energy consumption is somewhat increasing as a whole, with that of the people's livelihood/domestic sector and of transportation sector are rising. In the classification of fuels, electricity is growing in consumption. As an energy-saving vision, it aimed principally at personal surroundings in which every one got into the habit of saving energy continuously without being forced. The basic plan for the energy conservation drive consisted of inducement to an energy-saving life style, energy conservation to be spread by the next generation children, continuation of energy saving activity rooted in the region, and promotion of energy conservation as a basis for introducing new energy. The diffusion and enlightenment for children destined to lead the next generation were defined as a particularly important assignment, as was the promotion of energy conservation and environmental education.

Summarized herein are results of the studies on closed cycle MHD (CCMHD) power generation by the study committee. The studied system is based on the MHD gas turbine combined Brayton cycle of about 500,000 kW in output power, firing natural gas as the fuel, and the conceptual design works therefor are completed. The major findings are: the overall plant efficiency: 54.2% at the power transmission side, plot area required per unit power output: 0.04 m{sup 2}/KW, unit construction cost: 251,000 yen/KW, and unit power generation cost: 10.2 yen/KWh. This system will be more operable than the gas turbine combined cycle with steam system, because start-up time, output change rate, optimum load and so on are constrained not on the power generator side but on the gas turbine side. The expected environmental effects include the exhaust gas NOX concentration being equivalent with that associated with the conventional power generator of 2-stage combustion system, quantity of combustion gases to be treated being approximately 40% of that associated with the gas turbine combined cycle, and reduced CO2 gas emissions, resulting from enhanced power generation efficiency. It is expected that the CCMHD system can exhibit higher efficiency than the high-temperature gas turbine combined cycle system. (NEDO)

This report is a compilation mainly of distributed material. In the development of entrained bed coal gasification power generation, gasification is tested in a 2t/d-capable facility and gasification efficiency and operation characteristics are grasped, these constituting the studies of elements to assist pilot plant operation etc. The fluid temperature point of slag is found to decrease by 200 degrees C at the maximum upon addition of flux (CaO), and this improves on slag fluidity. For the development of a demonstration gas turbine, an experimentally built combustor is tested using a real gas. A combined cycle power system is studied by simulation. In the study of pilot plant operation, measures relative to slagging are implemented, inspection and maintenance are conducted for each facility, and the combustor for a demonstration plant is subjected to oil and coal combustion tests. In the study of a pilot plant for developing technologies for hydrogen production using coal, the plant stably runs more than 1,000 hours under 100% load at in a RUN-8-3 operation. Some deposit collects in the neighborhood of the contracted area of the blow nozzle and on some part in the slip stream, but it does not affect operation. No abnormalities are detected in the cyclone or heat recovery boiler. The pilot plant is let to continue its operation, and excellent results are achieved, which are beyond the targets of carbon conversion efficiency of 98% or higher and gas cooling efficiency of 78% or higher.

For waste water treatment facilities of S marine products industrial complex, a demonstrative test was carried out on a waste water treatment method in which addition of biological activity promoter `quillaia saponin` and the aerobic/anaerobic method are combined. In the S marine products industrial complex, there are more than 100 plants which deal mostly with salt-preserved and boiled-fish-paste products. The plant is operated by the activated sludge method with the pretreatment pressurized floatation. The capacity of the aeration tank and concentration tank for the experiment was 2600m{sup 3} and 110m{sup 3}, respectively. The amount of saponin added was approximately 3mg/L for the amount of influent (raw waste water). The measurement items were transparency, SS, COD, BOD, n-hexane extracts (oil content), MLSS, etc. As a result of the experiment, it was found that the equipment of flocculant addition and pressurized floatation as pretreatment facilities is not necessary; the activated sludge treatment of even the waste water in which n-hexane extracts are more than 100mg/L is possible without the pretreatment; and the n-hexane extracts in the treated water is less than 2mg/L. 7 refs., 7 figs., 6 tabs.

With an objective of discussing I-V characteristics when a shadow has appeared on part of a photovoltaic module, evaluations were given as a first stage of the study on saturation current, shunt resistance and series resistance for the solar cell module. As a result of measuring change in amount of power generated in a sunny day with a shadow appearing over the solar cell module, reduction in power generation capability of about 23% was verified. In other words, the I-V characteristics of the solar cell module change largely because of existence of the shadow caused on the module. The I-V characteristics curve may be expressed and calculated as a function of the shunt resistance and series resistance. By curve-fitting measurement data for a case of changing insolation without existence of partial shadow, values of the shunt resistance and series resistance were derived. As a result, it was found that the calculations agree well with measurements. It was made also clear that each parameter shows temperature dependence. 6 refs., 10 figs., 1 tab.

Modeling of artificial radionuclide transport in sea water is crucial for prognosis of radioecological situation in regions where dumping of radioactive waste had been made and/or accidents with nuclear submarines had taken place. Distribution of artificial radionuclides in bottom sediments can be a detector of radionuclide release from dumped or sunk objects to marine environment. Proper model can determine the dependence between radionuclide distribution in sediments and radionuclide release. Following report describes two-barrier model of radioactive agent transport in sea water. It was tested on data from 1994 - 2013 expeditions to Novaya Zemlya bays, where regular dumping of solid radioactive waste was practiced by the former USSR from the early 1960's until 1990. Two-barrier model agrees with experimental data and allows more accurate determination of time and intensity of artificial radionuclide release from dumped containers. (authors)

This survey was made to obtain the basic data for future spread and promotion of No.6 type (waste use type production facilities) and No.7 type (waste fuel production facilities) which were added to the objects having been subsidized since fiscal 1997 under `the environmental harmony type energy community project.` In the former, the kiln in the cement industry and the blast furnace in the steel industry can be extremely large places to receive waste plastic since the facilities are distributed in every area and the treatment capacity is large. However, the effective collection, transportation and sorting of large quantity of waste plastic, especially the problem of removal of vinyl chloride, is a big bottleneck. As to the use of waste plastic using gasification technology, there are no actual results on the commercial basis. That is, however, appropriate for treatment of the waste difficult in treatment, and can be expected of the usage in the chemical industry. In the latter, in the facilities using industrial waste raw materials as fuel, solidification and liquefaction are both operated on a commercial basis. In relation to the solidification and use as fuel of general waste, the treatment of combustion ash is preventing the expansion of use of waste in the industrial field because of a large quantity of chlorine included in the products. 92 refs., 54 figs., 35 tabs.

For the purpose of studying an expanse and characteristics of the geothermal system and a possibility of geothermal development in the Haneyama area, Oita Prefecture, geochemical survey was conducted. In the survey, various kinds of analyses were made for 13 specimens of hot spring water and 5 specimens of surface water in the area of about 280km{sup 2} at 402 measuring points of the concentration of Hg in soil gas. The results of the survey were as follows: In this survey area, it was thought that the HCO{sub 3} type geothermal water of a comparatively low temperature which was heated by the wide-spread conduction heat from the depths was widely distributed deeper than the depth of 500-700m, and it was presumed that a possibility was low of existence of a high geothermal potential which can be used for the geothermal power generation in the part deeper than the drilling depth of 700m. In the Noya area in the southwest part of the survey area, the high temperature deep geothermal reservoir was confirmed. In this area, the high temperature neutral-alkalescent Cl-SO{sub 4} type geothermal water was distributed in the depth of several 100 meters or deeper. The geothermal water seemed to flow from NE to SW along the structure in the NE-SW direction, and it was concluded that the area was the most promising one. (NEDO)

Although CDM system was provided in COP3 on climate change held in Kyoto in 1997, its detailed rules including project approval are yet undecided, and only the schedule to provide the detailed rules until COP6 in 2000 was decided in COP4 in 1998. The common recognition that the CDM project with plant exports produces various merits for both Japan and the partner country is increasing. However, from the viewpoint of forming concrete CDM projects, most Japanese enterprises are passive in approach to the CDM project because of no detailed design of CDM, uncertain profitability and procedures, and avoidance of additional burdens. Plant export is also difficult because of the fact that assessment of a new project is difficult. Enterprises' deeper recognition on the CDM project, and a governmental integrated support system are desirable. (NEDO)

For the contribution to elucidation of the geothermal structure in the Haneyama area in Oita Prefecture, gravity prospecting was conducted. Survey was carried out in the area of about 280km{sup 2} at 205 measuring points, and analysis was made altogether with the existing 3,273 gravity measuring points. As a result, the following were made clear. The gravity basement forms the fault-state structure that sinks several 100 meters to the south side on the line from the south edge of the Higashi-shiiya ridge to Mt. Kurotake - Mt. Daigansen - Amagase hot spring in the SW direction. This fault was made correspondent to the Beppu north fault on the east side of Mt. Kurodake. Each of the following regions is the region where the fault-state structure that predicts the development of fracture and the area of distribution of alteration zone that can be cap rock overlap each other: NW edge of Shishimuta sedimentation zone - Machida alteration zone distribution area; N edge of the Shishimuta sedimentation zone - Ibushi alteration zone/Noya alteration zone distribution area; Vicinity of Mt. Kurodake - Hijiu alteration zone distribution area. It seems that the above-mentioned regions have high potentiality of geothermal exploration. The region where new igneous activities are seen, which is near the heat source, is important for exploration. The distribution area is seen near the west of the Mizuwake Pass ridge. (NEDO)
