    The aim of this project was to increase the understanding of opportunities and problems connected with combustion of sorted waste fractions containing paper, wood and plastics (PWP-fuel) in fluidized bed boilers. An evaluation of the effect of sulphur containing additives in a PWP-fuel fired boiler was also performed within the project since this is not previously reported in open literature. The experience from two boilers at different plants, Johannes (BFB) and Hoegdalen P6 (CFB) during the firing season 2003/2004 was documented. In the Johannes boiler the main fuel is bark while Hoegdalen P6 combusts 100 % PWP-fuel. Analysis of the fuels shows that there are large differences between the two boilers. At Johannes the PWP-fuel contained low amounts of elements (chlorine, alkali and other metals) that are expected to result in increased operational problems or emissions. A large proportion of these unwanted elements came from the wood and paper fractions. The plastic fraction in Johannes had very low levels of unwanted elements. The fuel at Hoegdalen contained large amounts of elements such as chlorine, alkali and other metals that can cause operational problems. First of all the plastic fraction contained large amounts of chlorine, most likely from PVC, which results in a more corrosive atmosphere in the boiler. The fraction of fines in the Hoegdalen fuel contained larger concentrations of potassium and sodium compared with the other fuel fractions, substances that also are related to the formation of deposits. The fraction of fines in the fuel probably also results in combustion taking place high up in the boiler and to some extent continuing in the cyclones. The characterisation of the combustion behaviour performed in Johannes identified a maldistribution in O{sub 2}, CO and gas temperature over a cross-section of the furnace. This was not depending on the fuel mixture but is more likely depending on uneven fuel feeding or air distribution. A comparison between the different fuel mixtures shows that addition of PWP-fuel results in locally lower O{sub 2}-levels and higher CO-levels close to the front wall. This results in an increased risk for local corrosion on the furnace walls. The measurements in Johannes showed that co-combustion with PWP increased the alkali chloride concentration in the flue gas but an increase in the amount of deposits could not be measured. However, the deposits contained more chlorine during co-combustion of PWP, which should yield increased risk for corrosion. The increase can be correlated with the wood and paper fractions of the fuel. Injection of sulphate in the furnace resulted in increased SO{sub 2} concentration and reduced alkali chloride concentration, which resulted in reduced deposit formation. Addition of sulphate also reduced the chlorine concentration in the deposits thereby reducing the corrosion risk. The sub micron particles in the flue gas before gas cleaning mainly contain KCl and K2SO{sub 4} but with sulphate addition KCl to a large extent is converted to K{sub 2}SO{sub 4}. Altogether, this shows that this kind of fuel yields an increased risk for corrosion and deposits on superheaters and furnace walls. However, these problems can to a large extent be avoided by the addition of sulphur (concerning superheater corrosion) and adjustment of the air and fuel feed equipment (concerning furnace wall corrosion). Also in the tests in Hoegdalen the SO{sub 2} concentration increased and the alkali chloride concentration decreased in the flue gas when sulphur was added, resulting in decreased deposit formation. At the same time the chlorine concentration decreased and the sulphur concentration increased in the deposits. However, the chlorine concentration of the deposits was still high and did not decrease as much as in Johannes. Using elementary sulphur or sulphate as an additive had no noticeable influence on deposit growth or on the chemical composition of the deposits. Neither did the measurements show that sulphur containing additives decrease the corrosion rate during combustion of 100 % PWP (Hoegdalen). Both the investigated boilers have had serious problems with bed sintering during the firing season 2003/2004. There are large differences in the composition of the fly ash from the two boilers. In Johannes the concentrations of heavy metals were relatively low also during co-combustion with PWP and evenly distributed between the different particle sizes. Manganese, originating from the bark, was the heavy metal that dominated. The fly ash from Hoegdalen had significantly higher concentrations of heavy metals, mainly copper and lead. In Hoegdalen the heavy metals were enriched in the smallest particles. If fly ash particles larger than 10 {mu}m can be separated before the flue gas cleaning the amount of fly ash from the bag filter will be reduced. This is likely to result in a reduced amount of fly ash classified as hazardous waste and thereby also reduced cost for ash handling. The emissions from Johannes during co-combustion with 20 % PWP-fuel were relatively low, i.e. the HCl and SO{sub 2} concentrations were below 6 mg/Nm{sup 3} at 6 % O{sub 2} before flue gas cleaning. During the periods when the boiler was monitored also the CO concentration was well below the emission limit but there can be large variations in the emissions of CO over the firing season. The high manganese concentration in the ash from Johannes can possibly be limiting for the allowed emissions of particulates. However, with the current flue gas cleaning the emission limit for particulates should be met without any problems and consequently also the limit for heavy metals. Altogether there should not be any difficulties for this boiler to meet the flue gas emission limits set by the European waste combustion directive. Hoegdalen P6 is already adapted to the waste combustion directive and should not have any difficulties to meet the emission limits.

    The results from this project show that phosphorous-rich additives could be of interest to reduce fouling and high temperature corrosion without causing increase in slagging and/or bed agglomeration tendency for typical biofuels. General results in this series of experiments show that in order to achieve a good potassium-binding effect the calcium and magnesium content should be low in the phosphorous-rich fuel and additive. If the content of Ca and Mg is high in the final fuel mixture (including both P-fuel/additive and the bulk fuel) the K-binding effect is reduced and more P needs to be added. Of course, this also means that the additive of choice (fuel or chemical) should have a low content of calcium and magnesium. It is therefore probable that the best results will be obtained when using a fuel mix where the final blend has a molar ratio of P/(K+Na+2/3Ca+2/3Mg) approaching 1. For instance, using monoammonium phosphate, this would be equivalent to a cost (autumn 2009) of about 9-14, 10-15 and 30-40 SEK in P-additive cost per MWh of added fuel to achieve this molar ratio for typical logging residue, salix and wheat straw biofuels.

    This work has been done in order to find new raw material sources for an expanding pellet industry, combined with finding a use for a forest product that has no market today. The raw material has been forest from early thinning in two typical stands in Vaesterbotten. The purpose has been to evaluate this material as a raw material for producing pellets. Two typical stands have been chosen. One stand with only pine trees and one mixed stand dominated by birch. The soil of these stands was poor. Half of the trees were delimbed by harvest and half of the trees were not delimbed. This formed four different assortments that were handled in the study. After harvesting the assortments were transported to an asphalt area to be stored. Half of the material was stored during one summer and half of the material was stored during one year and one summer. The different assortments were upgraded to pellets and test combusted in the research plant BTC at the Swedish University of Agricultural Sciences, in Umeaa. The upgrading process contains of the following steps: 1.Chipping by a mobile chipper. 2.Low temperature drying (85 deg C). 3. Coarse shredding ({phi}15 mm). 4. Fine shredding ({phi}4-6 mm) and 5. Pelletizing (Die: {phi}8). Samples for fuel analysis were taken during the chipping. Analyses shows that the net calorific value for delimbed assortments are about 0,3 MJ/kg DM higher than for limbed assortments. Pellets made of the assortments Mixed limbed and Pine limbed has shown a net calorific value comparable to stem wood pellets. Pellets made of Birch delimbed show a net calorific value 0,4 MJ/kg DM lower than stem wood pellets. Analyses show that ash contents of the assortment Mixed delimbed was 1 %-unit higher compared to stem wood pellets. The assortment Pine delimbed and Birch delimbed has showed an ash contents comparable with stem wood pellets. The ash melting characteristics can reduce the value of a raw material. Low ash melting temperature for a fuel might cause huge problems by sintering in boilers and burners. Good quality stem wood pellets show an ash melting temperature >1500 deg C. The assortment Pine limbed which has shown the lowest ash melting temperature 1270-1320 deg C can be critical for combustion and needs very god temperature control to avoid sintering. For the rest of the different assortments, ash melting temperatures have been over 1500 deg C which indicates good ash melting characteristics. Emissions in flue gases were measured during test combustion. All measured parameters showed that this wood material from thinnings could be burned very efficiently and with low emissions. The largest difference was registered between emissions of NO{sub x} from the different assortments. The assortment Mixed limbed gave the highest NO{sub x} value 70 mg/MJ fuel, and the assortment Pine delimbed gave the lowest NO{sub x} value 46 mg/MJ fuel. Other emissions of CO, HC and SO{sub x} that were measured showed very low values. Pelletizing characteristics of the different assortments were defined by four different parameters: 1.Production capacity (kg/h), 2. Energy consumption (kWh/ton), 3. Density of produced pellets (kg/m{sup 3}) and 4. Durability of produced pellets. The measurements show that all assortments have pelletizing characteristics comparable with pure stem wood. Best results were obtained with Mixed limbed, which gave high production capacity and therefore low energy consumption, and durable pellets with acceptable density. The assortment Birch delimbed was most difficult to pelletize which resulted in high energy consumption and high-density pellets. After storing one year all assortments were pelletized again. Results from those tests show that pelletizing characteristics of the material had changed during storage. Assortment Mixed undelimbed and Birch delimbed could not be pelletized successfully. These materials could not be transported evenly enough in to the pelletizer. Material flow characteristics had changed during the storage. On the other hand assortment Pine delimbed and Pine undelimbed showed higher production capacity compared to the same material stored only one summer.

    Reduction of emissions of carbon monoxide and organic substances by injecting either ammonium sulphate or elemental sulphur and the importance of the point of injection has been investigated in full scale in a grate-fired bark boiler. The effect was monitored downstream of the economizer and air preheater, immediately upstream of the electrostatic precipitator. Concentrations determined in the comprehensive monitoring program include principally carbon monoxide, TOC and several organic substances, including PAH, PCDD/F and polychlorinated benzenes (PCBz). Additionally, the gaseous PAH were determined on-line using a novel mass spectrometer, REMPI-TOF MS, that measures specifically the 2- to 4-ring PAH's. All concentrations of substances of interest here fluctuate in concert and peak simultaneously. The relationship between the concentrations is not straightforward: there appears to be a threshold in carbon monoxide concentration. Below this threshold, the concentration of organics is low and above it concentrations increase rapidly with increasing carbon monoxide concentration. It has been confirmed that using sulphur additives not only reduces the concentration of carbon monoxide, but also that of organic substances in the flue gases. These additives do not only reduce the mean level of concentrations, but also dampen the fluctuations in these concentrations. Any measure leading to a reduction in carbon monoxide will also decrease the concentration of most organics, under the conditions prevalent in this boiler. Both additives tested are equally effective per kg of pure sulphur. The point of injection, in the fuel or above the grate, is not important. The PCDD/F concentration in the flue gases is very low even without additives, and the effect of sulphur on these emissions is therefore difficult to observe. Here, the effect is masked by the variation of data. The PAH concentration is lowered by an injection of sulphur additives. The variation in data is though rather large, which may be caused by variation in particle content in the gas samples

    The background to this project is the new EU directive 2000/76/EG regarding incineration of waste. This directive may have an effect on emission limits for Swedish plants firing waste wood. It may lead to needs of refurbishment in e.g. the area of flue gas cleaning equipment. In order to produce a basis to evaluate the need for such upgrading, measurement of metals, HCI, SO{sub 2} , CO, TOC and dioxin have been carried out on three plants firing wood waste: a grate boiler (Handeloeverket P11), one circulating fluid bed boiler (Aaterbruket in Lomma), and a bubbling fluidised bed boiler (Johannes in Gaevle, firing 50% waste wood). The measurements have mainly been carried out after boiler, equivalent to upstream flue gas cleaning. The results are that the demands of the EU directive on most points can be managed with existing equipment if this consists of electrostatic precipitator or bag filter with good performance and flue gas condensor. Without flue gas condensor, there is a need for other measures for 1-10 and for grate boilers, SO{sub 2} as well. The requirements in the directive for TOC is weaker than the demand on CO, and correspondingly, the demand on CO is driving. The level of dioxin from the boiler (upstream filter) exceeds allowed emission, and is in the range of 0,1-2 ng TE/Nm{sup 3} tg, 6 % O{sub 2} . Existing equipment will meet the emission limit for the lower levels (0,1-0,3) , but not safely for the higher levels (1,5-2). Correspondingly, there may be a need for equipment upgrading, e.g. in the form of activated carbon injection upstream flue gas filter.

    Effluent treatment of pulp and paper mills generates a biological sludge that according to Swedish implementation of EU-directives from 2005 has to be taken care of by incineration or by production of soil for agriculture or ground cover. An alternative way to take care of the sludge is incineration in the recovery boiler. This method is used in two Finish and two Swedish pulp mills with good results. The purpose of this project is to investigate the consequences for integrated pulp and paper mills when the biological sludge is incinerated in the recovery boiler. The biological sludge contents Non Process Elements, NPE, which increase the risks of incrustations in the system and increase the need of make up lime. This study comprises the following NPE: aluminum, silicon, phosphorus, chloride, potassium, manganese, magnesium, iron, copper, barium and calcium. The simulation program WinGEMS 5.0 (Pacific Simulation) was used in the study to predict the levels of NPE in the recovery system of the Kraft mills. Three different pulp and paper mills were selected for the study, Billerud Skaerblacka, ASSI Domaen Froevi and SCA Obbola. The mills are different concerning raw materials, process, degree of own produced pulp and paper products. All three the mills have effluent treatment and use the method of activated sludge that generates a surplus of biological sludge. The results of the study proved that for Skaerblacka mill the method is applicable. For Obbola the prerequisites are somewhat more complicated, the effluent treatment generates considerably higher amount of sludge per ton pulp produced due to the treatment technique and use of waste paper (40 %) for the paper machine. The high input of aluminum with the sludge will give troublesome incrustations of sodium-aluminum-silicate on the heat surfaces in the evaporation plant. To eliminate the aluminum from the system magnesium can be added to the black liquor which will precipitate as the double salt hydrotalcite in the green liquor and be rejected by the green liquor dregs. For Froevi mill the situation is somewhat more favorable compared to Obbola but a smaller amount of magnesium has still to be added to avoid incrustations of sodium-aluminum-silicate in the evaporation plant. The need of make-up lime will increase due to the content of phosphorus in the biological sludge which otherwise will be build up in the lime. The increased need of make up lime was estimated to 2 kg/ADt for Skaerblacka and Froevi while Obbola will need about 2-3 kg/ADt. Experience from mills that employ incineration of biological sludge in the recovery boiler shows that NO{sub x} in the flue gas has not increased. For Skaerblacka and Froevi the increase of nitrogen by the biological sludge will be moderate and will probably not give any increased formation of NO{sub x} in the flue gas. For Obbola the amount of nitrogen by the sludge will be higher which increases the risks of having higher levels of NO{sub x} in the flue gas. The other NPEs as chlorides, potassium, calcium, manganese, iron, cupper, barium and calcium will not give any problems for the recovery system. The study proves that it is possible for an integrated pulp and paper mill to evaporate and incinerate the biological sludge in the recovery boiler. Disadvantages as increased need of make up lime and also the necessity of adding magnesium when using this method should be compared with benefits and drawbacks with other methods that are available. Costs of the methods must be calculated based on the actual pulp and paper mill.

    The feasibility of commercially available boilers in the interval 50 kW to 1 MW for use with reed canary grass (RCG) as fuel has been preliminary evaluated. The capacity to handle the large ash volumes generated by RCG both in terms of ash withdrawal and combustion quality was used as the main criteria. Nine boilers and two burners were identified and classified in a three-step scale from verified functioning on RCG to possible functioning with some design changes

    This study has provided an initial picture of where the most interesting ports and areas available for future expansion of a maritime infrastructure for LNG. On the basis of supplying vessels with LNG as fuel, from a long term perspective, we recommend locating LNG terminals in or near major ports and around the big ship routes. Given the current age distribution of ships operating waters of the Baltic Sea, almost 20% of the vessels are 30-40 years old and likely to be replaced by 2015 - 2020. Thus, there is a potential for newly built ships will be equipped with LNG operation. Selected criteria s; Size of the LNG terminal and hence the need for the size of the fairway and the area of land. Proximity to traffic routes with much ship traffic. Proximity to the major port. Proximity to consumers on the land side. On the basis of selected criteria and analyzed for possible location of the terminal it can be noted that a number of Swedish ports are found suitable. For example, ports of Sundsvall, Gothenburg and Helsingborg has been identified as suitable, but with different starting point and different types and sizes of terminals possible.

    The conversion potential to replace oil in the energy intensive industries and diesel in heavy transport is estimated in the study to 6.8 TWh and 10 TWh per year, respectively. Several alternative fuels compete for this conversion potential. What fuels will take market share depends on several factors such as price, availability of fuel, availability of process technology and vehicles, technology development and possible future technological advances. For liquid methane to compete a new infrastructure is required that in a cost effective manner makes it possible to distribute the liquid methane to the regions where the need is the greatest. With today's distribution system, including truck delivery from import terminals in Nynaeshamn and Fredrikstad, virtually the entire southern Sweden is within reach of LNG deliveries. The study points out three nodes, Gaevle, Sundsvall and Luleaa, which is suitable for distribution of liquid methane to the central and northern Sweden. The three hubs are suitable for freight transfer to trucks as well as rail and shipping. A strategic nationwide network of refueling stations is also proposed, with a total of 18 new stations, in addition to the filling stations in southern and central Sweden that are already planned or in operation. Both the availability and use of liquid methane in Sweden today is limited. Liquid natural gas, LNG (liquefied natural gas), is primarily used as a backup to biogas plants, in a few industries and as supply for a few filling stations for compressed gas. The availability of LNG and also liquid biogas (LBG liquefied biogas), will increase in coming years. In 2011, two new LNG import terminals are put into operation in Nynaeshamn and Fredrikstad in Norway and two additional import terminals are planned in Gothenburg and Lysekil. Furthermore, two production plants for liquid biogas production have started, and four additional plants are planned, which together will produce around 0.5 TWh LBG annually. It is also likely that in the coming years there will be almost ten filling stations for liquid methane in operation in southern Sweden. The market analysis shows that several industries in the iron and steel industry are already interested in converting to LNG, mainly to cope with environmental demands. Also in the chemical industry there is an interest in using LNG, while many of the companies in the pulp and paper industry do not see LNG as a particularly attractive option. The latter have access to their own fuel and several companies have also adopted policies aiming at becoming fossil fuel free in the near future. The total conversion potential to replace oil with LNG industry amounted to 6.8 TWh/year, divided among 100 users. The greatest potential is in central Sweden (Dalarna, Gaevleborg, Vaermland) and along the Norrland coast. With today's distribution system, including truck delivery from import terminals in Nynaeshamn and Fredrikstad, virtually the entire southern Sweden is within reach of LNG deliveries. Transport distance is too long to be economically feasible to supply industries in central and northern Sweden. To provide these regions with LNG the intermodal freight terminals in Gaevle, Sundsvall and Luleaa would be able to function as strategic hubs. These three terminals covering the areas and industries that according to the market analysis is most interesting for LNG supplies, and are all well connected both by road, rail and seaway, allowing for transfer between different modes. All harbours also have the potential to qualify for receiving LNG deliveries by ship. There is also an interest in using liquid methane for heavy transport and coaches/intercity buses, because the distribution of liquid methane is cost effective, and the vehicles get longer range due to the high energy density of liquid methane. Yet, however, the availability of vehicles is limited and the infrastructure is not developed, but both the availability of vehicles and refueling stations will increase in coming years. In total, about 10 TWh/year of diesel needs to be replaced i n the heavy vehicle sector, among other reasons to meet environmental goals, which is assumed to correspond to the conversion potential in the heavy duty vehicle sector in the long term (2030). A rough estimate of the possible development means that the demand for biomethane, in the form of LBG, and CBG (compressed biogas), by 2020 will amount to 1.5 TWh/year for heavy duty transport applications and to about 1 TWh/year LNG for long-range heavy duty transport. Furthermore, it is estimated to be possible that the production capacity of LBG double by 2020, reaching around 1 TWh/year.

    It is possible to burn impregnated wood containing copper in a biofuel boiler if the boiler has suitable flue gas cleaning equipment. The studied facility needs to complete its flue gas treatment with a dust control step (such as electrostatic precipitator, fabric or bag filter). If the incineration surpasses 50 tonnes of waste per year a special permission is required. Smaller quantities requires only a notification. In combustion of wood chips with an admixture of up to 20% copper-impregnated wood (50% sapwood and 50% kernel) the bottom ash stands clear of all minimum and maximum levels according to the Forestry Board's recommendations for using the ash as a fertilizer in forestry. The findings from the ash leaching tests show that chromium leaching from bottom ash of samples 4 and 5 is too high to allow deposition of the ashes in landfills along with non-hazardous wastes (the rest of the ash passed all the benchmarks). A hazard analysis has been carried out where the concept of toxicity index (TI) has been applied

    The main objectives of this study were to identify and calculate the additional costs to energy plants of combustion of agro fuels instead of wood chips, and to determine the potential farmers have to influence fuel quality and thus identify parameters that could be used for pricing in the future. The overall aim is to increase the volume of agro fuels produced. Four agro fuels were considered in this study: willow, straw, husks and reed canary grass. These four were selected because data were available on their combustion at energy plants and because they are representative of different categories of agro fuels: short rotation coppice, crop by-products, seeds and grass. Data were obtained through literature surveys, telephone interviews with farmers, researchers, advisors and contractors, and visits to six energy plants. Combustion properties for each crop and data on combustion were compared. Measures that could be taken by farmers to improve fuel quality today and perhaps in the future were estimated. Although information and experience proved to be lacking in this area, it was possible to identify some potential measures, which are listed below for each fuel. To promote expansion of the agro fuel market, issues concerning business contacts and forms of organisation were examined. The choices and preferences of farmers as regards sale and delivery are influenced by a number of different factors, which were investigated here by studies of the literature and interviews with farmers. There was little documentary evidence available on combustion of agro fuels. Short-term trials have been carried out on small amounts of a number of crop species without specific documentation of emissions, maintenance costs, ash handling, etc. The additional costs to energy plants for combustion of agro fuels compared with wood chips were investigated on visits to energy plants by collecting data directly and by interviewing plant personnel. The additional costs were then calculated for each fuel and type of boiler, but the specific conditions prevailing in any individual plant will obviously affect the actual costs. General conclusions were: Additional costs for an outage caused by the agro fuel depend on whether there is an accumulator to cover some of the load, and on the other types of boilers and equipment available. Additional costs for ash handling depend on the technical system and business agreements concerning ash handling, which differed between the energy plants visited. Additional costs arising when a boiler and/or fuel is new can be reduced by hard work and experience. In one example (Saatenaes), feeding a new boiler with new straw with a moisture content of 20-22% caused problems with fuel feeding, more frequent soot blowing, etc. Through persistent efforts and feedback on straw quality to farmers, these problems have been eliminated. In two cases, 100% agro fuel was combusted during part load periods. In one case full load could not be achieved because of low bulk density and resulting limitations of the feeding system, and in the other case high load was known to cause problems with fouling and dust production. Using agro fuels during part load was not considered an additional cost. At the two combined heat and power plants (CHP-plants) visited, the upper limit for willow in the fuel mix was set at 15%, since additional costs caused by increased fouling are expected beyond this level (based on experience). This study has mainly focused on the cost for a plant to change from forestry fuels to agro fuels. However, a more common issue is to co-combust a cheaper fuel. This is especially true for larger boilers mainly due to the fact that the fuel availability is more uncertain if large quantities of agro fuels shall be used, and that problems like increased deposit or corrosion rate shall be avoided. Therefore this investigation has looked both at cases with combustion of 100 % agro crops (Jordbro, Kvaenum, Graestorp and Saatenaes) and at cases with co-combustion (Enkoeping and Eskilstuna). Co-combustion of agro fuels with another fuel can reduce the problems that might arise due to the fuel properties of the agro fuels, and has therefore an influence on the rate of extra costs. To increase the market for agro fuels, there is a need for: Information to farmers about existing crops and potential buyers. Initiatives from the energy companies are desirable. Tangible information to suppliers on the structure of the whole chain and the need to grow and deliver consistent amounts. Contract forms that give farmers an acceptable risk. A dialogue between farmers and the energy companies concerning the quality changes that can be achieved by decisions at harvest, storage, transport and price-setting, etc

    The Swedish Radiation Safety Authority, SSM, has issued an ordinance on ash contaminated with Cesium-137. It implies amongst other things that ash containing 0,5 - 10 kBq/kg Cesium-137 (so-called contaminated ash) can be used for geotechnical purposes provided that the content in a near-by well does not exceed 1 Bq/litre and that the increase in a near-by fish producing recipient does not exceed 0,1 Bq/litre. The initial plan with the presently reported work was to provide a compilation of how the ordinance for Cesium-137 can be applied in practical work. It became evident, however, in the course of the work that issues related to the co-variation between potassium and Cesium needed further investigation. As a result, the present report comprises also a compilation of this extended information search. Cesium-137 is present in ash as a result of the accident in a nuclear power reactor in Chernobyl in 1986 during which material having a very small grain size was spread to a high altitude. A few days later, Cesium-137 was deposited during rains over large parts of Sweden. This activity penetrated to a depth of one or a few decimetres during the course of the subsequent few days and weeks, after which it was partially taken up by plants and spread in the ecosystem. Section 2 has the character of a handbook. It provides basic information on radiation, and also about the ordinance and other material from the SSI. Section 3 comprises compilations of relevant international status of knowledge. This regards how potassium and Cesium behave in soil and ash, and also how spreading of Cesium can be modelled. Cesium behaves similarly to Potassium but with the difference that Cesium is bonded much more strongly to mineral soil and ash. Potassium and Cesium appears in soil in four different forms: dissolved in the pore water, exchangeable, non-exchangeable and as bonded to minerals. The amount dissolved in the pore water is the smallest and that bonded to minerals is the largest. The differences are large. The transitions between Cesium/Potassium in the pore water and in the exchangeable positions are rapid. Other transitions are slow. Over the course of a few years, Cesium becomes bonded as non-exchangeable and after a few decades, the content of non-exchangeable and mineral Cesium may be comparable in magnitude. The migration rate depends on the availability. Before Cesium-137 in fallout becomes absorbed, it is transported with the water, and this is the reason for the initial rapid penetration into soil on the order of a decimeter. When most of the Cesium-137 has become non-exchangeable and mineral, the migration rate may be as low as on the order of a millimetre per year. There is an interesting finding to report about clay. For short term migration, i e shortly after a fallout, clay provides a retention that is far superior to that of sand. This is probably related to the fact that clay contains many more positions for ion exchange as compared to sand. After some time when most of the Cesium appears in non-exchangeable and mineral positions, clay and sand are comparable. It might be tempting to assume that organic soils would provide a good retention since they can absorb nutrients from artificial fertilizers and keep them available to plants. Measurements have shown, however, that Cesium-137 may migrate rapidly in soils that lack a mineral component, e g soils consisting of peat. This can be assumed to relate to the fact that the bonding to the many exchangeable positions is much weaker as compared to those in non-exchangeable and in mineral positions. The data on ash are scarce. The data found indicate that the availability of Cesium-137 is high in fresh ash, but that the bonding is remarkably strong already after a few years. It cannot be taken for granted without further information that fresh water conditions apply also when the salt content in the pore water is high. Investigations have shown, however, that the solid mineral phase prefers Cesium before potassium also in such cases. Although the difference between potassium and Cesium is smaller, it is nevertheless sufficient for separation of Cesium from chloride in a migration situation. After such a separation has taken place, the distribution coefficients for fresh water conditions may be applied. In section 4, techniques that have been developed previously in the Swedish Ash Programme are applied to Cesium-137 in soil containing some mineral matter. The result is that the content of Cesium-137 in near-by wells and lakes become insignificant and far below the limits issued by the SSM. Exceptions to this are pure organic soils, soils made up entirely of lime, and water that drains on the surface. The results of this analysis are utilized in Section 5 as a basis for suggestions for a simple control programme as well as practical advice.

    The aim of this project is to evaluate how the operation conditions and the combustion chemistry is changed in a Bubbling Fluidized Bed (BFB) Boiler when adding approx. 20 wt-% Biomal into the fuel mixture. The following issues were addressed in the project: 1. How does the new chemical composition of the fuel mix influence bed agglomeration, deposit growth, ash flows, flue gases and particle size distribution? 2. Is it possible to run the boiler at a reduced bed temperature of about 750 deg C due to the increased moisture content originating from the biomal fuel? The project is based on combustion tests in the two Waste to Energy boilers at 20 MWth each owned by Boraas Energy and Environment AB (BEM). Furthermore, results from the Waste Refinery Project 'Reduced bed temperature in FB-boilers burning waste - part II' has been used as reference in some cases. At normal conditions the boilers are run on a fuel mixture containing 80 % sorted industrial waste and 20 % household waste. This fuel mixture consists mainly of paper, plastics and wood. In Boraas the organic part of the household waste is sorted out and used for biogas production. With the addition of biomal, which consists of animal by-products crushed to a pumpable fuel, the chemical composition of the fuel mixture is changed to some extent. The results from the combustion tests shows that biomal influences the chemical fuel composition, but also that there are large variations in the ordinary waste fuel composition as well. The most evident changes with addition of biomal are: 1. Increased moisture. 2. Reduced heat value. 3. Increased amount nitrogen, calcium and phosphorus. 4. Decreased amount lead due to the low concentration in biomal. However, there were no changes in sodium, potassium, sulphur and chlorine, elements important for increased/reduced fuel related problems, derived from biomal. The increase of calcium and phosphorus with biomal derive from bone and the calcium-phosphates influenced to some extent the sand/ash flows were the largest change was an increase in the amount of phosphorus and calcium. In addition a decrease of the amount of lead was seen in all ash flows. The calcium-phosphates were stable during combustion and no reactions of phosphorus with other elements were detected. The results from the trials in this project show that co-combustion of biomal had the following positive effects on the boiler performance: 1. The bottom bed temperature decreased, but > 20 % biomal is needed to reach 750 deg C. 2. The risk for bed agglomeration was decreased. 3. The NO{sub x} emission was reduced at the same time as the addition of ammonia was reduced. 4. The deposition rate of the deposits collected on the test probe was reduced, thus no increased risk in deposit formation on the superheater tubes. The conclusion is that the boiler could be operated in a safe way with addition of biomal.

    During combustion of fossil fuels, SO{sub 2} is released to the atmosphere. Because of environmental concern with acid rain, the capture of SO{sub 2} is a very important process. Fluidized bed combustion (FBC) is a combustion method where limestone may be added to the furnace chamber to capture SO{sub 2} as the stable product CaSO{sub 4}. In the present work a relatively simple laboratory method has been developed for characterizing limestone reactivity with SO{sub 2}. The reactivity data from such investigations are used, together with residence time and particle size distribution, in a sulfur capture model for fluidized bed boilers that predicts the sulfur capture as a function of the Ca/S molar ratio. In addition, the model predicts the conversion of CaO to CaSO{sub 4} for all particle sizes present in a boiler. The model was developed and verified using data from two boilers, a 12 and a 40 MW circulating fluidized bed boiler, and showed reasonable agreement for both boilers. In addition to the development of a sulfur capture model, the effects of SO{sub 2} and CO{sub 2} concentrations, particle size, temperature variations, and reducing conditions on the sulfation reaction was studied using a fixed-bed quartz reactor. The sulfation reaction was also studied for long periods of time, up to 60 hours. This was done because of the long residence times of certain particle sizes that may exist in a fluidized bed boiler. From the parameter study it was found that particle size and variations between oxidizing and reducing conditions had a large effect on the sulfation behaviour. The investigation of long sulfation times showed that the reaction continued even at high degrees of conversion, although at a very slow rate. CO{sub 2} concentration had a moderate effect on the sulfation reaction while temperature variations showed no effect on the final conversion between CaO and CaSO{sub 4}. 29 refs, 25 figs, 4 tabs

    Agricultural derived solid fuels are more problematic to combust in small-scale heating plants than conventional wood fuels. Their high content of ash, chlorine and sulphur leads to increased emissions of dust, sulphur dioxide and hydrogen chloride in the flue gases. By transporting the flue gases to a flue gas well where it condenses, and separates dust and sour components, enables a cost effective flue gas purification for small-scale heating plants (50 kW - 10 MW) of agricultural derived solid fuels. This project have studied two heating plants using flue gas wells with the aim to add to the knowledge about how a flue gas wells may look like and to quantify how much emissions of dust, chlorine and sulphur in the flue gases are reduced. The project also aimed to summon regulations and laws regarding the handling of the condensate that develop in the flue gas well. In the project measures were conducted on two different heating plants with mounted flue gas wells: a 60 kW biofuels boiler combusting grains and red canary grass and a 1 MW batch fired boiler combusting wheat straw. Measurements on flue gases were conducted with and without water injection in the flue gases. The flue gas wells reduced dust emissions of up to 80 %. The best reduction was achieved at the 60 kW heating plant when firing red canary grass. Firing grains in the same plant lead to 7 % reduction of the dust emissions. In the 1 MW heating plant firing wheat straw the flue gas well accomplished 40 % reduction of dust emissions. The boiler ability to achieve complete combustion, hence minimize the content of volatile and semi-volatile components in the flue gas, is largely affecting the flue gas well ability to reduce dust emissions. This did not, however, affect the reduction of dust in the flue. Chlorine emissions was reduced by up to 88 % by a flue gas well. Water injection made a big difference on reduction of chlorine emission from grain combustion. Sulphur emissions was reduced by 50 %, from wheat straw combustion, by a flue gas well. No reduction of sulphur was achieved from grains combustion in the 60 kW heating plant and water injection had little or no effect on the reduction rate. As the condensate was very acetic and potentially erosive an ejector fan was used to cool down the flue gases enough to enable acid resilient plastic pipes to be used for the flue gas canal. The well was drained of condensate continuously and the piping must be sweeped with regular intervals to prevent blockage of the flue gas. Plants below 20 MW is excluded from national regulations on activity emission regarding flue gas condensate. The Swedish Environmental Code does however place the responsibility for preventing harm to nature upon the practicer. The possibilities of managing the condensate from the flue gas well are spillage to a manure reservoir for spreading it as fertilization on farmland, or spillage directly to receiving waters. The later method require neutralization of the pH, commonly by using sodium hydroxide, but possibly also limestone

    Full Text Available Ultralyd billeddanning er i dag den beste undersøkelsesmetoden vi har til å overvåke fosterets utvikling og vekst. Ultralydmåling av fosterets størrelse og biometriske referansetabeller for svangerskapet brukes til å fastsette svangerskapets alder, beregne termin og vurdere fosterets vekst. Optimal studiedesign er ulik for hvert av disse formålene. Det er stor variasjon i fysiologisk vekst og en utfordring å identifisere fostre som har dårlig tilvekst. En enkeltmåling av fosteret kan fortelle oss om det er lite eller stort i forhold til andre fostre, men ikke om størrelsen er passelig i forhold til forventet fysiologisk vekst for dette fosteret. Tilpassede referansemodeller ("customised" justerer forventet størrelse i relasjon til føtale og maternelle faktorer og har vist seg å bedre identifisere sanne veksthemmede fostre enn bare å klassifisere i henhold til 2,5, 5 eller 10 persentilen. Men et foster som i utgangspunktet er stort for alderen, men etter hvert vokser langsomt vil ikke nødvendigvis bli fanget opp ved en slik enkeltmåling. Serielle målinger vil hjelpe, men en slik longitudinell metode blir ikke fullt ut utnyttet før det appliseres betinget ("conditional" vekstberegning. Betingelsesleddene for variasjon i vekst og målemetode kalkuleres ut fra longitudinelle data og kan så anvendes for det enkelte foster. En første måling brukes til å beregne forventet vekst og variasjon for en neste måling.

The particles vary widely in size distribution and chemical/physical characteristics. PM is often divided into size fractions with different aerodynamic diameters: PM10 (PM ! 10 mm, PM2.5 (PM ! 2.5 mm and PM0.1 (PM ! 0.1 mm. Recent population studies have found an association between an increase in mortality and morbidity due to lung and/or cardiovascular disease and short-term increases in PM. The relative risk (RR was approximately 1.005 for an increase in 10 mg/m3 PM10, without an observed threshold even at concentrations below 10 mg/m3. Chronic exposure has been investigated to a lesser extent, but longterm exposure to PM2.5 has been found to be associated with an approximately 10-fold greater increase in RR than short-term exposures. Experimental studies with volunteers in chamber and field studies show mild lung or cardiovascular responses at concentrations of ambient particles (PM2.5/PM10: 100-200 mg/m3 that may occur during episodes of air pollution. Animal studies at higher concentrations have shown stronger responses. The experimental studies support the epidemiological evidence for an adverse health effect of PM. Both population- and experimental studies indicate the existence of vulnerable individuals. At low to average ambient concentrations there seems to exist a discrepancy between the results of population- and experimental studies that might be due to the absence of the most vulnerable individuals in the experimental studies. Together with cell culture experiments, human and animal studies indicate the importance of physical and chemical properties of the particles (size, content of metals, organics, endotoxins, etc. for

    The market of forest products is expanding and thus resulting in more expensive biomass fuels. Therefore research within the combustion industry for alternative fuels is needed, for example cultivated fuels. Combustion and gasification research on these cultivated fuels are limited. The objectives of this work was to increase the general knowledge of silicon rich cultivated fuels by study the agglomeration characteristics for wheat straw, reed canary grass and industrial hemp in combination with commercial bed materials. Controlled fluidized bed agglomeration tests was conducted in a 5 kW, bench-scale, bubbling fluidized bed reactor. The tendencies of agglomeration were determined with the three cultivated fuels in combination with various minerals present in natural sand (quarts, plagioclase and potassium feldspar) and an alternative bed material (olivine). During the experiments bed samples and formed agglomerates were collected for further analyses with a scanning electron microscope (SEM) and with X-ray microanalysis (EDS). Wheat straw had the highest agglomeration tendency of the studied fuels followed by reed canary grass and industrial hemp. No significant layer formation was found around the different bed particles. Instead, the ash forming matter were found as individual ash sticky (partial melted) particles in the bed. The bed material mineralogical composition had no influence of the agglomeration process because of the non layer formation propensities of the used silicon rich fuels.

    The energy market of today is turbulent and it is quite clear that big changes in the consumption pattern are going to occur, due to the expansion in Asia and the expected Climate Change. The EU has, as a first step, stated in a directive that the consumption of renewable energy in the heat and power sector should be increased to 20 % and in the transportation sector to 10 % by the year 2020, a target which is high above current levels in most of the EU countries. It is reasonable to believe the European demand of renewable energy will create a shortage of biomass and that the development and use of technology for energy production will therefore not only depend on what is technically possible. One scenario is that biomass is mainly used for the markets that have very few alternatives, such as the transportation sector and small scale CHP units. We have today a relatively high electrical consumption through a stable grid and district heating nets in almost all densely populated areas. Large high efficiency power plants combined with heat pump technology will probably prevent any significant expansion of the district heating nets. A third major net for gas distribution seems not to be a feasible solution. Local nets for production of biogas from wet waste for different purposes, including EvGT units with 55% efficiency may however be good solution for some areas. There are a number of cycles and technical solutions to increase the electrical efficiency which could be applied also on smaller plants. The total efficiency will however not increase, only the el/heat ratio and it is not obvious that the higher investment cost for indirect cycles, bottom cycles or extreme steam data in combination with the risk of lower availability is a feasible solution. Especially waste to energy plants, with their need of high utilisation time, are sensitive to long production interruptions. The existing heat sinks in Sweden will however be efficiently used for electrical production of some kind, though they can be expected to be decreased due to warmer climate and energy efficiency measures in buildings. The big manufacturers and energy companies are today heavily involved in RandD to develop climate friendly fossil fuel plants. The goal is to increase the efficiency and to develop the CCS-technology. With the amount of money involved it is plausible that they are going to be successful and that Post Combustion technology will be commercial around the year 2015, OxyFuel/Carbon around 2020 and Chemical looping after year 2030. This development includes also a significant efficiency increase, mainly based on material development and development of oxygen and carbon dioxide separation. It can be assumed that Sweden in the year 2030, as the other countries in the EU union, will produce electricity mainly in large high efficiency plants with low CO{sub 2} emissions. The plants could be natural gas fired combined cycles (efficiency without CCS of eta{sub el} = 65%), coal fired CHP-plants (efficiency without CCS eta{sub el} >55%) and/or nuclear power plants at our coast line. Inland there could be waste and bio fired CHP plants and Pulp and paper plants, both types producing biofuel from all the different types of biomass that are available

    Fox, S. E.; Griswold, J.

    2011-12-01

    The Arctic Visiting Speakers (AVS) Series funds researchers and other arctic experts to travel and share their knowledge in communities where they might not otherwise connect. Speakers cover a wide range of arctic research topics and can address a variety of audiences including K-12 students, graduate and undergraduate students, and the general public. Host applications are accepted on an on-going basis, depending on funding availability. Applications need to be submitted at least 1 month prior to the expected tour dates. Interested hosts can choose speakers from an online Speakers Bureau or invite a speaker of their choice. Preference is given to individuals and organizations to host speakers that reach a broad audience and the general public. AVS tours are encouraged to span several days, allowing ample time for interactions with faculty, students, local media, and community members. Applications for both domestic and international visits will be considered. Applications for international visits should involve participation of more than one host organization and must include either a US-based speaker or a US-based organization. This is a small but important program that educates the public about Arctic issues. There have been 27 tours since 2007 that have impacted communities across the globe including: Gatineau, Quebec Canada; St. Petersburg, Russia; Piscataway, New Jersey; Cordova, Alaska; Nuuk, Greenland; Elizabethtown, Pennsylvania; Oslo, Norway; Inari, Finland; Borgarnes, Iceland; San Francisco, California and Wolcott, Vermont to name a few. Tours have included lectures to K-12 schools, college and university students, tribal organizations, Boy Scout troops, science center and museum patrons, and the general public. There are approximately 300 attendees enjoying each AVS tour, roughly 4100 people have been reached since 2007. The expectations for each tour are extremely manageable. Hosts must submit a schedule of events and a tour summary to be posted online

  4. Efficient Software HEVC to AVS2 Transcoding

    Directory of Open Access Journals (Sweden)

    Yucong Chen

    2016-09-01

    Full Text Available The second generation of Audio and Video coding Standard (AVS is developed by the IEEE 1857 Working Group under project 1857.4 and was standardized in 2016 by the AVS Working Group of China as the new broadcasting standard AVS2. High Efficient Video Coding (HEVC is the newest global video coding standard announced in 2013. More and more codings are migrating from H.264/AVC to HEVC because of its higher compression performance. In this paper, we propose an efficient HEVC to AVS2 transcoding algorithm, which applies a multi-stage decoding information utilization framework to maximize the usage of the decoding information in the transcoding process. The proposed algorithm achieves 11×–17× speed gains over the AVS2 reference software RD 14.0 with a modest BD-rate loss of 9.6%–16.6%.

  5. Arvelig hemokromatose - nytten av screening

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Arvelig hemokromatose fører til jernopphopning i kroppen, men gir sjelden alvorlig helseskade. Nesten alle hemokromatosepasienter i vårt land er homozygote for C282Y-mutasjonen i HFE-genet. Omtrent 7 per 1000 innbyggere har denne genotypen. Alvorlig syke blir bare omkring 5-15% av homozygote menn og nesten ingen kvinner. Likevel er det holdepunkter for at screening for hemokromatose blant friske, yngre menn kan være kostnadseffektivt. Det er relativt lett å påvise om en person er disponert for sykdommen, i god tid før den bryter ut, og forebyggende behandling er billig og effektiv. Imidlertid kan vi ikke forutsi hvilke screeningpositive personer som ubehandlet får alvorlig sykdom. Et kontrollert forsøk med screening bør gjennomføresHereditary hemochromatosis – benefits of screening. Hereditary hemochromatosis leads to iron accumulation in the body; however, serious illness due to hemochromatosis is rare. In Norway, almost all patients with hemochromatosis are homozygous for the C282Ymutation in the HFE-gene, a genotype carried by about 7 per 1000 inhabitants. Serious complications are seen in only about 5-15% of homozygous men and in very few women. Nevertheless, screening young men for hemochromatosis may be cost-effective. Detecting predisposed men is relatively straightforward, and prophylactic treatment is cheap and effective. However, we can not predict, among screen-positive men, the few who untreated will become seriously ill. A controlled screening trial should be conducted.

  7. Fractional order absolute vibration suppression (AVS) controllers

    Science.gov (United States)

    Halevi, Yoram

    2017-04-01

    Absolute vibration suppression (AVS) is a control method for flexible structures. The first step is an accurate, infinite dimension, transfer function (TF), from actuation to measurement. This leads to the collocated, rate feedback AVS controller that in some cases completely eliminates the vibration. In case of the 1D wave equation, the TF consists of pure time delays and low order rational terms, and the AVS controller is rational. In all other cases, the TF and consequently the controller are fractional order in both the delays and the "rational parts". The paper considers stability, performance and actual implementation in such cases.

    PurposeThe study was designed to assess outcomes of arteriovenous (AV) accesses after interventional stent-graft deployment in haemodialysis patients.Materials and Methods63 haemodialysis patients with 66 AV fistulas and AV grafts were treated by interventional stent-graft deployment from 2006 to 2012 at our hospital. Data of these patients were retrospectively analysed for location of deployed stent-grafts, occurrence and location of (re-)stenosis and (re-)thrombosis. Complex stenosis was the most frequent indication for stent-graft deployment (45.5 %), followed by complications of angioplasty with vessel rupture or dissection (31.8 %).ResultsA high rate of procedural success was achieved (98.5 %). The most frequent location of the deployed stent-graft was the draining vein (66.7 %). Stent-graft deployment was more frequent in AV grafts than in AV fistulas. Primary patency was 45.5 % at 6 month, 31.3 % at 12 month and 19.2 % at 24 month. Primary patency was significantly better for AV fistulas than for AV grafts with deployed stent-grafts. Patency of the deployed stent-graft was much better than overall AV access primary patency with deployed stent-graft. Re-stenosis with thrombosis was the most frequent indication for re-intervention. Most frequent location of re-stenosis was the draining vein (37.1 %), followed by stenosis at the AV access (29.5 %) and the deployed stent-graft (23.5 %).ConclusionRe-stenosis and re-thrombosis remain frequent in AV fistulas and AV grafts in haemodialysis patients despite stent-graft deployment. Re-stenosis of the deployed stent-graft is, only in the minority of the cases, responsible for AV access dysfunction.

    Full Text Available Skolen er stadig i medienes søkelys, og i denne artikkelen ser vi nærmere på hvordan forskere bidrar med sine fagkunnskaper i skoledebatten i mediene. Den problemstillingen vi ønsker å besvare, er: Hvilken rolle har forskere i norske avisers dekning av skole? For å svare på dette har vi gjort en analyse av samtlige artikler om skole i VG, Bergens Tidende og Aftenposten i 2013. Resultatene viser at det forekommer en navngitt forsker i ca. 12 % av avisenes artikler om skole (209 av 1712 artikler. Det er imidlertid forskjell mellom avisene, og i VG opptrer det forskere i ca. 24 % av artiklene om skole, mens andelen både i Aftenposten og BT er ca. 11 %. Undersøkelsen viser videre at det er mange forskere som får mulighet til å uttale seg om skole i disse tre avisene, men det store flertallet av disse uttaler seg kun én gang. Vi fant også at forskere ofte uttaler seg om rammene for skolens undervisningsvirksomhet, og sjelden om det som foregår i klasserommene. Resultatene av vår empiriske undersøkelse stemmer i stor grad overens med hovedtendensene i tidligere studier av forskere i media, noe som indikerer at forskernes rolle i norske avisers skoledekning ikke skiller seg markant ut fra den rollen forskere har i media generelt. Våre resultater peker imidlertid på én viktig forskjell: Forskere ser ut til å være uvanlig godt synlige i norske avisers dekning av skole.Nøkkelord: skoleforskning, media, forskningsformidlingAbstractSchool is a frequently debated topic in the media, and this article investigates how researchers contribute with their knowledge in this media debate.

    Directory of Open Access Journals (Sweden)

    Helle Margrete Meltzer

    2009-11-01

    Full Text Available  SAMMENDRAGI perioden 1999-2001 vil det bli gjennomført tre kostholdsundersøkelser som til sammen skal kartlegge konsum avmatvarer med betydning for inntaket av miljøgifter i Norge, fortrinnsvis kadmium, kvikksølv, PCB og dioksiner.Disse giftene finnes hovedsakelig i krabbe, flatfisk, skjell, gjedde og abbor, lever eller nyre fra vilt og viltvoksendesopp. Fordi gjennomsnittskonsumet er lavt, spørres det ikke spesifikt om disse matvarene i landsdekkende kostholdsundersøkelsersom 'Norkost'. Hensikten med studien er å kunne gi en bedre beskrivelse av eksponeringsfordelingeni befolkningen med tanke på miljøgifter. Fordelingen er antakelig skjev, dvs. et stort antall personerventes å ha et lavt inntak og noen få personer ventes å ha et relativt høyt inntak av de undersøkte stoffene. Eventuelleukjente risikogrupper vil kunne avdekkes, og det er av stor interesse å undersøke hvor stor eksponeringen i deutsatte gruppene er.Del A av undersøkelsen er landsdekkende og omfatter en postal frekvensundersøkelse til 10 000 tilfeldig valgtepersoner mellom 18 og 79 år. Del B omfatter en postal frekvensundersøkelse til 6000 tilfeldig valgte personer i sekskommuner, der tre er kystkommuner og tre er innlandskommuner. Kommunene blir valgt ut fra kjennskap til godtilgang på de aktuelle matvarene. Vi antar at der tilgangen på matvarene er god, er konsumet høyere. Del C avundersøkelsen vil omfatte høykonsumenter av aktuelle matvarer, valgt fra del B av undersøkelsen. Dette vil være endybdestudie der analyser av miljøgifter i blod, hår og urin også skal inngå.Undersøkelsen er den første i sitt slag her til lands og vi kjenner ikke til at tilsvarende studier er gjort i andreland. Hensikten med artikkelen er å gi en beskrivelse av undersøkelsen i en tidlig fase av gjennomføringen.Meltzer HM, Bergsten C, Stene LC, Stigum H, Wiborg ML, Lund-Larsen K, Alexander J. Consumption ofcontaminated foods – Description of a dietary survey

    Full Text Available Medisinsk forskning har ført til store framskritt de siste tiårene. Det er investert mye mer ressurser på basalforskning og klinisk forskning enn på å utvikle og evaluere metoder for å sikre at pasientene får nytte av forskningen. Formålet med implementeringsforskning er å redusere gapet mellom forskning og praksis, ved å utvikle og evaluere tiltak som kan sikre at behandlingen som pasientene mottar er kunnskapsbasert, at den er omsorgsfull og av god kvalitet.I denne artikkelen gjør vi rede for hva implementering og implementeringsforskning er. Vi belyser historikken til denne unge vitenskapen, og illustrerer mangfoldet i de faglige tilnærmingene og begrepene som brukes om det å få forskning brukt i praksis. Det finnes en rekke teorier om endring av atferd, både på individnivå og på organisatorisk nivå. Teoriene er imidlertid i liten grad testet empirisk, særlig når det gjelder å endre atferd i helsetjenesten.Systematiske oversikter over metodisk gode studier er den beste kilden til informasjon om effekt av implementeringstiltak. The Cochrane Effective Practice and Organisation of Care Group (EPOC er en viktig kilde for slike oversikter. De systematiske oversiktene som er utarbeidet på dette feltet viser at passive dissemineringstiltak har begrenset effekt, mens mer aktive tiltak kan ha liten til moderat effekt. Det er ofte betydelig variasjon i effekt på tvers av studiene. Det er derfor viktig å få bedre kunnskap om hvilke faktorer som kan forklare slike forskjeller i effekt.Vi gir eksempler på norske implementeringsstudier, og refererer bidrag fra forskere ved Kunnskapssenteret. Implementeringsforskningen kan, hvis den lykkes, sikre pasientene bedre behandling.Flottorp S, Aakhus E. Implementation research: science for improving practice.

  15. Pollen transmission of asparagus virus 2 (AV-2) may facilitate mixed infection by two AV-2 isolates in asparagus plants.

    2014-09-01

    Asparagus virus 2 (AV-2) is a member of the genus Ilarvirus and thought to induce the asparagus decline syndrome. AV-2 is known to be transmitted by seed, and the possibility of pollen transmission was proposed 25 years ago but not verified. In AV-2 sequence analyses, we have unexpectedly found mixed infection by two distinct AV-2 isolates in two asparagus plants. Because mixed infections by two related viruses are normally prevented by cross protection, we suspected that pollen transmission of AV-2 is involved in mixed infection. Immunohistochemical analyses and in situ hybridization using AV-2-infected tobacco plants revealed that AV-2 was localized in the meristem and associated with pollen grains. To experimentally produce a mixed infection via pollen transmission, two Nicotiana benthamiana plants that were infected with each of two AV-2 isolates were crossed. Derived cleaved-amplified polymorphic sequence analysis identified each AV-2 isolate in the progeny seedlings, suggesting that pollen transmission could indeed result in a mixed infection, at least in N. benthamiana.

    In this study, we demonstrated that a derivative of imidazole, AVS-1357, is a novel skin-whitening compound. AVS-1357 was found to significantly inhibit melanin production in a dose-dependent manner; however, it did not directly inhibit tyrosinase. Furthermore, we found that AVS-1357 induced prolonged activation of extracellular signal-regulated kinase (ERK) and Akt, while it downregulated microphthalmia-associated transcription factor (MITF) and tyrosinase. It has been reported that the activation of ERK and/or Akt is involved in melanogenesis. Therefore, we examined the effects of AVS-1357 on melanogenesis in the absence or presence of PD98059 (a specific inhibitor of the ERK pathway) and/or LY294002 (a specific inhibitor of the Akt pathway). PD98059 dramatically increased melanogenesis, whereas LY294002 had no effect. Furthermore, PD98059 attenuated AVS-1357 induced ERK activation, as well as the downregulation of MITF and tyrosinase. These findings suggest that the effects of AVS-1357 occur via downregulation of MITF and tyrosinase, which is caused by AVS-1357-induced prolonged ERK activation. Taken together, our results indicate that AVS-1357 has the potential as a new skin whitening agent.

    Since the arrival of the Dawn spacecraft at 4 Vesta on July 16, 2011 the Visible and InfraRed Imaging Spectrometer (VIR) has acquired hyperspectral images of Vesta's surface, which enable to characterize Vesta's mineralogical composition in the wavelength range from 0.25 to 5.1µm. As part of the analysis of Vesta's surface composition the science team is preparing a series of 15 quadrangle maps showing the results derived from the spectroscopic analysis of the VIR and FC color data. We present preliminary results of the spectroscopic analysis achieved for the quadrangles Av-2 (Belicia) and Av-3 (Caparronia), which show Vesta's surface between 21°N - 66° N°, 0° - 90°E and 90° - 180° E, respectively. These results are based on the analysis of the combination of the visible albedo, spectral parameters including the position, depth of the pyroxene absorptions, as well as color ratio composites using the VIR channels centering at 749nm/438nm (Red), 749nm/917nm (Green) and 438nm/749nm (Blue). Vesta's rotation axis, however, is tilted ~29° with respect to its orbital plane. Since Dawn arrived during northern winter, portions of Vesta north of ~45° N are dominated by extended shadows or have not yet been imaged due to permanent night. Thus, limited FC color or VIR hyperspectral data have been available for the quadrangles Av-2 and Av-3. The illuminated parts are dominated by a heavily-cratered northern terrain with ancient troughs and grooves and named after the prominent relatively large impact craters Belicia (~37°N/48°E) and Caparronia (~36°N/167°E). Numerous impact craters of different size, morphology, and state of surface degradation are apparent. Most spectral variations are strongly affected by the extreme illumination conditions, making the analysis of albedo variations and spectral signatures rather difficult. Their interpretation thus remains. Nevertheless, VIR spectra show clear evidence of Vesta's surface composition similar to those of HED

  1. Cofactor requirement of HpyAV restriction endonuclease.

    Directory of Open Access Journals (Sweden)

    Siu-Hong Chan

    Full Text Available BACKGROUND: Helicobacter pylori is the etiologic agent of common gastritis and a risk factor for gastric cancer. It is also one of the richest sources of Type II restriction-modification (R-M systems in microorganisms. PRINCIPAL FINDINGS: We have cloned, expressed and purified a new restriction endonuclease HpyAV from H. pylori strain 26695. We determined the HpyAV DNA recognition sequence and cleavage site as CCTTC 6/5. In addition, we found that HpyAV has a unique metal ion requirement: its cleavage activity is higher with transition metal ions than in Mg(++. The special metal ion requirement of HpyAV can be attributed to the presence of a HNH catalytic site similar to ColE9 nuclease instead of the canonical PD-X-D/EXK catalytic site found in many other REases. Site-directed mutagenesis was carried out to verify the catalytic residues of HpyAV. Mutation of the conserved metal-binding Asn311 and His320 to alanine eliminated cleavage activity. HpyAV variant H295A displayed approximately 1% of wt activity. CONCLUSIONS/SIGNIFICANCE: Some HNH-type endonucleases have unique metal ion cofactor requirement for optimal activities. Homology modeling and site-directed mutagenesis confirmed that HpyAV is a member of the HNH nuclease family. The identification of catalytic residues in HpyAV paved the way for further engineering of the metal binding site. A survey of sequenced microbial genomes uncovered 10 putative R-M systems that show high sequence similarity to the HpyAV system, suggesting lateral transfer of a prototypic HpyAV-like R-M system among these microorganisms.

    Sediment and overlying water samples were collected at 10 sampling stations at Xinan Creek, a tidal river in Pearl River Delta, and analyzed for physical and chemical characteristics as well as microbial incicators, in order to reveal the main factors dominating the spatial distribution of acid volatile sulfide (AVS). The effects of Eh, SRB OC and TS on the spatial distribution of AVS were investigated and the impact of AVS on the toxicity of heavy metals in the studied area was evaluated. The results showed that the range of AVS was 0.207-41.453 micromol x g(-1), with an average of 6.684 micromol x g(-1), which is relatively high compared to the results in other studies. The AVS value of the surface layer was higher than the bottom layer in 5 stations. The AVS values in both the surface layer and the bottom layer were highly variable, the coefficients of variation being 93.61% and 153.09% , respectively. The analytical results revealed that TS was the factor with the greatest impact on the spatial distribution of AVS, and the order was TS > OC > Eh > SRB. Potential ecological risk of heavy metals existed in 60% of the smpling stations based on the value of Sigma (SEM5-AVS), however, with the criterion of [Sigma(SEM5-AVS)]/foc, none of them had inacceptable ecological risk. Furthermore, in terms of single species of heavy metals, there was certain risk of toxic effect for all the five heavy metals (Cd, Ni, Cu, Zn and Pb). The above mentioned results will provide valuable data for the in-depth study of the formation mechanism of AVS and helpful reference for environmental impact assessment and scientific rehabilitation of heavy metals in polluted rivers.

    A 60-year-old man presented with recurrent abdominal pain and weight loss for 6 months. Abdominal imaging showed a large vascular lesion in the head and neck of pancreas suggestive of arteriovenous malformation (AV malformation). Endoscopic ultrasound was done which showed features of AV malformation with no evidence of pancreatic malignancy. Surgery was planned for definitive treatment of malformation. Digital subtraction angiography with angioembolization was done prior to surgery to reduce vascularity of the lesion. He recovered after a pylorus preserving pancreaticoduodenectomy. Histopathology of the resected specimen confirmed the pancreatic AV malformation. There has been no recurrence at 2 years of follow-up.

    Directory of Open Access Journals (Sweden)

    William W. Brabham, M.D.

    2013-06-01

    Full Text Available Cardiac resynchronization therapy is an effective therapy for patients with left ventricular systolic dysfunction and a ventricular conduction delay; however, approximately 30% of patients do not experience significant clinical improvement with this treatment. Modern devices allow individualized programming of the AV delay and VV offset, which offer the possibility of improving clinical response rates with optimized programming. AV and VV delay optimization techniques have included echocardiography, device-based algorithms, and several other novel noninvasive techniques. While an acute improvement in hemodynamic function has been clearly demonstrated with optimized device settings, long-term clinical benefit is limited. In the majority of cases, an empiric AV delay with simultaneous biventricular or left ventricular pacing is adequate. The value of optimization of these intervals in “non-responders” still requires further investigation.

  17. Lesing av delvis motstridende tekster i syvende klasse

    Directory of Open Access Journals (Sweden)

    Wenke Mork Rogne

    2013-06-01

    Full Text Available I denne artikkelen ser vi på hvilken type informasjon elever i 7. klasse vektlegger for å konstruere en sammenhengende oppsummering av fire til dels motstridende tekster. Elever møter ofte flere tekster om samme tema – multiple tekster – og vi trenger økt kunnskap om hvordan de leser slike tekster. Elevene leste fire ulike tekster om en sykkelulykke. Tekstene presenterte informasjon som var delvis sammenfallende på tvers av alle tekstene, og delvis motstridende informasjon som innebar at enkelte tekster ga ulike beskrivelser av hendelsesforløpet. Vi testet elevenes ordavkodingsferdigheter, fikk dem til å fylle ut et spørreskjema om lesevaner og vi innhentet elevenes resultater på Nasjonal leseprøve. Etter lesing ba vi elevene gi en oppsummering av sykkelulykken. Elevene gjenga relativt mer sammenfallende informasjon enn motstridende informasjon. Gode resultater på Nasjonal leseprøve ser ut til å ha en sammenheng med elevenes ferdigheter i å konstruere en sammenhengende forståelse av de fire tekstene. Elever som oppga å lese mye på Internett hadde imidlertid fått med mindre av informasjonen som var felles for de fire tekstene i sine oppsummeringer. Vi fant også en negativ sammenheng mellom fritidslesing på Internett og resultatene fra Nasjonal leseprøve. Samlet sett indikerer resultatene at når elevene skal skape sammenheng mellom flere delvis motstridende tekster, så blir sammenfallende informasjon vektlagt mer enn motstridende informasjon. Dessuten ser det ut til at de elevene som bruker mest fritid til å lese på Internett, sliter mer med å sammenfatte innholdet i de fire tekstene enn de andre elevene.

  15. Analysis of AVS-penogram in 3000 impotent patients

    Energy Technology Data Exchange (ETDEWEB)

    Minn, Young Guy; Choi, Hyung Ki [Yonsei University College of Medicine, Seoul (Korea, Republic of)

    1994-09-01

    Audio visual simulation penogram(AVS-penogram) is used as a screening method for evaluation of erectile dysfunction. In this study, 3000 patients were evaluated from Dec. 1986 to Dec. 1992 and finally diagnosed by comprehensive diagnostic methods. The patients were classified according to AVS-penogram curves into 4 types and correlated with the patient`s final diagnosis. For 800 patients who were evaluated with combined AVS-penogram and NPT monitoring, compatibility ratios between psychogenic and organic group were compared. After correlating each of the curve type with the patients and comparing erotic and nocturnal erection, following results were obtained. 1. The mean age of the patients was 41.25 years. 2. The overall rate of final diagnosis were 57.5%, 14.3%, 8.9% in psychogenic, arteriogenic and veogenic impotence. 3. Type I group was proved as psychogenic impotence in 87% of the patients. 4. Type IIA group was proved as organic impotence in 79% of the patients and most of them had neurogenic and arteriogenic impotence. 5. Type IIB group was proved as psychogenic impotence in 51%, organic impotence in 49% of the patients. Among the organic impotence group, most of them had arteriogenic, venogenic and neurogenic impotence. The difference of both group was statically insignificant. 6. Type IIC group was proved as psychogenic impotence in 39%, organic impotence in 61% of the patients. Further studies are needed for sub-classification of both groups. 7. The compatibility ratio of the AVS-penogram and NPTM was 85.9% in psychogenic group with normal finding in both tests and 44.7% in organic group with abnormal finding in both tests. In conclusion, AVS-penogram is a primary diagnostic method in screening impotent patients and type I is regarded as psychogenic impotence. In Type IIB and IIC, sub-classification of curve type is needed for differential diagnosis between psychogenic and organic impotence. (Abstract Truncated)

    2009-10-01

    Full Text Available  SAMMENDRAGSvalbard er spesielt godt egnet til å vurdere påliteligheten av selvrapportert alkoholkonsum. På grunn av detlave prisnivået for alkohol er ulovlig import eller hjemmeproduksjon av alkohol ukjent på Svalbard. Dessutener samfunnet lite og oversiktlig, slik at det er praktisk mulig å undersøke hele befolkningen. I den aktuellestudien registrerte vi alt salg av alkohol til fastboende nordmenn på Svalbard i oktober og november 1988. Isamme tidsperiode ble alle nordmenn 18 år eller eldre invitert til å ta del i en helseundersøkelse der det inngikkspørsmål om alkoholbruk. Vi fant at selvrapportert alkoholkonsum utgjorde rundt 40% av salgsvolumet.På grunn av de spesielle forhold når det gjelder alkoholomsetning på Svalbard er det grunn til å anta atestimatet i denne studien er mer pålitelig sammenlignet med tilsvarende studier fra andre områder.Høyer G, Nilssen O, Brenn T, Schirmer H. The reliability of self-reported alcohol consumption.The Svalbard study 1988-89. Nor J Epidemiol 1996; 6 (1: 109-113.ENGLISH SUMMARYThe Norwegian island of Spitzbergen, Svalbard offers a unique setting for validation studies on self-reportedalcohol consumption. No counterfeit production or illegal import exists, thus making a complete registrationof all sources of alcohol possible. In this study we recorded sales from all agencies selling alcohol onSvalbard over a two month period in 1988. During the same period all adults living permanently on Svalbardwere invited to take part in a health screening. As part of the screening a self-administered questionnaire onalcohol consumption was introduced to the participants. We found that the self-reported volume accounted forapproximately 40 percent of the sales volume. Because of the unique situation applying to Svalbard, theestimate made in this study is believed to be more reliable compared to other studies using sales volume tovalidate self-reports.

    Full Text Available A whole I frame AVS real-time video encoder is designed and implemented on FPGA platform in this paper. The system uses the structure of the flow calculation, coupled with a dual-port RAM memory between/among the various functional modules. Reusable design and pipeline design are used to optimize various encoding module and to ensure the efficient operation of the pipeline. Through the simulation of ISE software and the verification of Xilinx Vritex-4 pro platform, it can be seen that the highest working frequency can be up to 110 MHz, meeting the requirements of the whole I frame real- time encoding of AVS in CIF resolution.

    Full Text Available Norges Idrettsforbund og Olympiske og Paralympiske Komité (NIF har en uttalt målsetting om en åpen og inkluderende idrett. Hvordan kommer dette til uttrykk i den praktiske virksomheten? Denne artikkelen, som bygger på data fra en undersøkelse om likestilling og mangfold i den organiserte idretten (NIF, retter søkelyset mot arbeid med inklusjon av ungdom med minoritetsbakgrunn på ulike organisasjonsnivå i NIF: særforbund, idrettskretser og idrettslag. Datamaterialet er kvalitative intervju med representanter fra ulike organisasjonsnivå. Resultatene viser at NIFs overordnede politikk i varierende grad nedfelles i særforbundenes virksomhet, i idrettskretsene og i idrettslagene. Av særforbundene skiller Fotballforbundet og Klatreforbundet seg ut som aktive pådrivere i arbeidet med inkludering. Mange idrettslag oppfattet slike spørsmål som lite aktuelle i sitt rekrutteringsområde. Representanter for lag som hadde erfaring med inkludering og rekruttering av minoritetsungdom, tilkjennega varierte erfaringer og synspunkter.

    2016-06-01

    Full Text Available Artikkelen tar utgangspunkt i tre observasjoner av en gutt på fire år som bruker iPad på fritiden. Den søker å synliggjøre de strategiene dette barnet velger for å skaffe seg tilgang til ulike medietekster, hvordan han leser og tolker dem, og den undersøker eventuelle spor av kritisk refleksjon hos barnet over disse tekstene. Teoretisk sett hviler den på en forståelse av mediekompetanse som en parallell prosess til utvikling av lese- og skrivekyndighet (literacy, og medieopplevelsene omtales som viktige møter med tekst. Artikkelen undersøker hvordan å lese medietekster kan legge et grunnlag for å utvikle en utvidet tekstkompetanse eller mediekompetanse. Konklusjonen legger vekt på motivasjon og lekenhet som barns primære inngang til medietekstene og som et grunnlag for å utvikle mediekompetanse (media literacy. The article is based on three observations of a four-year-old boy who uses the iPad in his spare time. It demonstrates the strategies that this boy applies to gain access to various media texts, and how he reads and interprets them. It also seeks to examine traces of critical reflection that he may demonstrate in relation to these texts. Theoretically, it rests on an understanding of media literacy as a parallel process to the development of literacy, and it seeks to demonstrate how reading media texts can create an important starting point for the development of media literacy. The Kindergarten practitioner’s role and opportunities to develop children's media literacy within a kindergarten context is a focus towards the end of the article. In conclusion, I argue that motivation and playfulness are important approaches to media texts and create an important foundation for the development of media literacy

Som parametre på intrauterinevekstforhold ble informasjon om fødselsvekt og gestasjonsalder fra Medisinsk Fødselsregister benyttet.Informasjon om rapporterte øreinfeksjoner ble basert på spørreskjemaer som ble besvart av tvillingene ialderen 18–25 år. Først studerte vi individuelle effekter av fødselsvekt og gestasjonsalder på forekomsten avotitis media (OM. Rapportert fødselsvekt hos individer med OM var signifikant lavere enn hos kontrollene,med en gjennomsnittsforskjell på 86 gram. Hos de som rapporterte OM var gjennomsnittlig gestasjonsalder3 dager kortere enn i kontrollmaterialet. Deretter beregnet vi effekten av fødselsvekt ved bruk av co-twinkontroll metoden.

    Full Text Available  SAMMENDRAGSpanskesyken var en verdensomspennende influensaepidemi som tok livet av minst 30 millioner mennesker,de fleste i løpet av noen få høstmåneder i 1918, men den strakk seg også inn i 1919. En siste svakbølge fant sted vinteren 1920. De første sporadiske tilfellene av spanskesyken i Norge oppsto i militærleirei begynnelsen av april 1918. Over tre måneder senere kom de første spredte tilfellene av det som skullevise seg å være starten på en ny stor influensapandemi. De første av disse oppsto i Kristiania, mest sannsynligetter smitteimport fra Skottland over Nordsjøen. Sommeren 1918 spredte spanskesyken seg raskt frasør til nord, fra kysten til innlandet innover fjordene, og fra de største byene og industrisentra via mindrebyer og andre tettsteder til landsbygda langs de viktigste ferdselsveiene. Da spanskesyken blusset opp igjenhøsten 1918 spredte den seg langsommere og trolig fra nord til sør, fortsatt fra kysten innover fjordene,men spredning fra byene langs kommunikasjonsveiene var mindre fremtredende. Vinteren 1918/19opptrådte influensaen spredt og sporadisk, tilsynelatende uten bestemt spredningsmønster og rekkefølge.Jernbanen, hurtigruten og automobilrutene spilte trolig en viktig rolle i spredningsprosessen, spesielt andrehalvår 1918.

    Full Text Available På et fotballag i overgangen mellom barne- og ungdomsfotballen er spilletid på fotballbanen under kamp både en knapp ressurs og en kilde til diskusjoner om fordeling. Spørsmålet som er utgangspunkt for denne artikkelen, er hvilke hensyn som bør tas når trener og lagleder skal fordele samlet spilletid på enkeltspillere. Er det viktigst å vinne fotballkampen, eller har det størst betydning å fordele spilletiden mest mulig likt mellom spillerne? Skal det tas hensyn til guttenes evner, motivasjon og preferanser? Er deres familiebakgrunn og personlighet av betydning? Diskusjonen baserer seg på en gjennomgang av ulike politiske rettferdighetsteorier for fordeling av knappe goder.Nøkkelord: rettferdighet, practice, fordelingsrettferdighet, diskursetikk, idrettsetikkEnglish summary: Minutes of justice: Distribution of time during football matches in a boys' teamDuring a football match, time for playing can be considered as a limited good. In this article the point of departure is the redistribution of time in a boys' football team in the transition phase between children and youth football. The questions are how and under which conditions time for playing should be distributed among the players. Is winning the game more important than trying to let every player play for an equal amount of time? Should the boys' talents, motivation, and preferences be considered while distributing time, or are family background and personality of importance? Different theories of political justice for the distribution of limited goods underpin the discussion of how to distribute the minutes of playing time during a football match.http://dx.doi.org/10.5324/eip.v4i1.1737

  3. Artificial vision support system (AVS(2)) for improved prosthetic vision.

    Fink, Wolfgang; Tarbell, Mark A

    2014-11-01

    State-of-the-art and upcoming camera-driven, implanted artificial vision systems provide only tens to hundreds of electrodes, affording only limited visual perception for blind subjects. Therefore, real time image processing is crucial to enhance and optimize this limited perception. Since tens or hundreds of pixels/electrodes allow only for a very crude approximation of the typically megapixel optical resolution of the external camera image feed, the preservation and enhancement of contrast differences and transitions, such as edges, are especially important compared to picture details such as object texture. An Artificial Vision Support System (AVS(2)) is devised that displays the captured video stream in a pixelation conforming to the dimension of the epi-retinal implant electrode array. AVS(2), using efficient image processing modules, modifies the captured video stream in real time, enhancing 'present but hidden' objects to overcome inadequacies or extremes in the camera imagery. As a result, visual prosthesis carriers may now be able to discern such objects in their 'field-of-view', thus enabling mobility in environments that would otherwise be too hazardous to navigate. The image processing modules can be engaged repeatedly in a user-defined order, which is a unique capability. AVS(2) is directly applicable to any artificial vision system that is based on an imaging modality (video, infrared, sound, ultrasound, microwave, radar, etc.) as the first step in the stimulation/processing cascade, such as: retinal implants (i.e. epi-retinal, sub-retinal, suprachoroidal), optic nerve implants, cortical implants, electric tongue stimulators, or tactile stimulators.

Hyppigere forekomst av bivirkninger kan forklares delvis,men ikke fullstendig, av at kvinner som gruppe konsumerer oftere og flere legemidler. Videre har legemiddelbrukhos kvinner i mange tilfeller tilknytning til biologiske tilstander som menstruasjon, graviditetog menopause, og den øker med alderen.

Frequent occurrence of adverseevents can partly, but not totally, be explained by the fact that women as a group consume more drugsthan men. Women’s drug consumption can to a certain degree be related to menstruation, pregnancyand menopause, and increases with age. It is essential to take into account cultural differences that cancontribute to an overestimation of the gender effect of adverse drug events.

This physiologic condition does not extend more than 1 cm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpful in the study of the normal cardiac physiology.

    UNIPASS is a general-purpose probabilistic computer program consisting of three major modules, including preprocessor, solver and postprocessor. UNIPASS contains a user-friendly Graphical User Interface (GUI), numerous state-of-the-art probabilistic analysis techniques, a large library of statistical distributions and a function module with a large library of support functions that can easily define any complex limit-state function in a scripting FORTRAN-like syntax format. Its inverse probability analysis and sensitivities analysis capabilities make it a powerful design aid in any product cycle. Its precise numerical analysis engine is accurate enough to push the failure probabilities of a design to well below 10 (exp -50). UNIPASS is equipped with advanced artificial intelligence that is designed to handle systems with an essentially unlimited number of random variables with ease and efficiency. Its modular arrangement allows you to tailor an analysis to the desired level of accuracy and efficiency. The depth and comprehensiveness of UNIPASS are built upon the decades of experience and expertise of industry leaders including Boeing Aircraft, NASA and the DoD. Its rich content also makes UNIPASS a valuable instructional tool for random processes and probabilistic mechanics. The topics include: 1) Reliability in AvSP; 2) Role of UNIPASS in AvSP; and 3) Examples. This paper is in viewgraph form.

    In 20 patients with known or suspected supratentorial arteriovenous malformations, an attempt was made to see how far CT angiography with 3-dimensional reconstructions is able to make a diagnosis and to differentiate the various components of the angioma. Spiral CT was performed following an intravenous bolus injection of 60-80 ml of iodine containing contrast medium. In all patients the diagnosis was confirmed by intra-arterial DSA of the vertebral vessels. In 13 patients, av malformations could be diagnosed following multiplanar 3-D reconstructions which agreed with the findings on DSA. The large supplying vessels, the nidus and the large draining veins could be defined with certainty. In 6 patients follow-up examination after embolisation was performed. The results could be demonstrated in three dimensions and the success of treatment could be documented unequivocally. CT angiography with 3-D reconstruction is able to supply important information in the majority of intracranial av malformations, both during initial investigation and following treatment. (orig.)

    Queiroz, Hermano Melo; Nóbrega, Gabriel Nuto; Otero, Xose L; Ferreira, Tiago Osório

    2018-01-01

    Acid-volatile sulfides (AVS) formation and its role on trace metals bioavailability were studied in semi-arid mangroves. The semi-arid climatic conditions at the studied sites, marked by low rainfall and high evapotranspiration rates, clearly limited the AVS formation (AVS contents varied from 0.10 to 2.34μmolg -1 ) by favoring oxic conditions (Eh>+350mV). The AVS contents were strongly correlated with reactive iron and organic carbon (r=0.84; r=0.83 respectively), evidencing their dominant role for AVS formation under semi-arid conditions. On the other hand, the recorded ΣSEM/AVS values remained >1 evidencing a little control of AVS over the bioavailability of trace metals and, thus, its minor role as a sink for toxic metals.

    2017-01-01

    This article demonstrates how the influential scholar Edgar Dale, alongside a generation of educational technologists, helped build an essential place for AV materials and pedagogical methods in the American classroom. It also shows that, for decades, the Payne Fund philanthropy supported multimedia research agendas that shaped ideas about teaching and technology, far beyond involvement in their famed studies on motion pictures and children in the 1930s. With his writings and research programs, Dale advanced concepts of media experience and systematicity, which came to be understood as common sense to the information society. In so doing he was a leading contributor to the discursive and ideological structure of our age of technological and informational abundance.

  19. Prevalence of E/A wave fusion and A wave truncation in DDD pacemaker patients with complete AV block under nominal AV intervals.

    Directory of Open Access Journals (Sweden)

    Wolfram C Poller

    Full Text Available Optimization of the AV-interval (AVI in DDD pacemakers improves cardiac hemodynamics and reduces pacemaker syndromes. Manual optimization is typically not performed in clinical routine. In the present study we analyze the prevalence of E/A wave fusion and A wave truncation under resting conditions in 160 patients with complete AV block (AVB under the pre-programmed AVI. We manually optimized sub-optimal AVI.We analyzed 160 pacemaker patients with complete AVB, both in sinus rhythm (AV-sense; n = 129 and under atrial pacing (AV-pace; n = 31. Using Doppler analyses of the transmitral inflow we classified the nominal AVI as: a normal, b too long (E/A wave fusion or c too short (A wave truncation. In patients with a sub-optimal AVI, we performed manual optimization according to the recommendations of the American Society of Echocardiography.All AVB patients with atrial pacing exhibited a normal transmitral inflow under the nominal AV-pace intervals (100%. In contrast, 25 AVB patients in sinus rhythm showed E/A wave fusion under the pre-programmed AV-sense intervals (19.4%; 95% confidence interval (CI: 12.6-26.2%. A wave truncations were not observed in any patient. All patients with a complete E/A wave fusion achieved a normal transmitral inflow after AV-sense interval reduction (mean optimized AVI: 79.4 ± 13.6 ms.Given the rate of 19.4% (CI 12.6-26.2% of patients with a too long nominal AV-sense interval, automatic algorithms may prove useful in improving cardiac hemodynamics, especially in the subgroup of atrially triggered pacemaker patients with AV node diseases.

    TIME VARIATION OF AV AND RV FOR TYPE Ia SUPERNOVAE BEHIND NON-UNIFORM INTERSTELLAR DUST ABSTRACT We investigate the time variation of the visual extinction, AV, and the total-to-selective extinction ratio, RV, resulting from interstellar dust in front of an expanding photospheric disk of a type Ia supernova (SN Ia). We simulate interstellar dust clouds according to a power law power spectrum and produce extinction maps that either follow a pseudo-Gaussian distribution or a lognormal distribution. The RV maps are produced through a correlation between AV and RV. With maps of AV and RV generated in each case (pseudo-Gaussian and lognormal), we then compute the effective AV and RV for a SN as its photospheric disk expands behind the dust screen. We find for a small percentage of SNe the AV and RV values can vary by a large factor from day to day in the first 40 days after explosion.

    2008-01-01

    Sediment treatment and sediment storage may alter sediment toxicity, and consequently biotic response. Purpose of our study was to combine these three aspects (treatment-toxicity-biotic response) in one integrated approach. We used Acid Volatile Sulfide (AVS) concentrations as a proxy of the disturbance of the sediment. AVS and Simultaneously Extracted Metal (SEM) concentrations were compared to bioassay responses with the freshwater benthic macroinvertebrate Asellus aquaticus. Storage conditions and sediment treatment affected AVS but not SEM levels. AVS can be used as a proxy for sediment disturbance. The best way to pretreat the sediment for use in a bioassay in order to maintain initial AVS conditions was to sample the sediment with an Ekman grab, immediately store it in a jar without headspace, and freeze it as soon as possible. In a survey using seven different sediments, bioassay responses of A. aquaticus were correlated with SEM and AVS characteristics.

    Computers, consumer, and communications are converging and fusing. The key device in homes in the near future will be an audiovisual hard disk drive (AV-HDD). The reason is that there is no other AV cash memory with high capacity, high speed, and a low price than the HDD. Fuji Electric has early started developing an AV magnetic hard disk, a core-functional element of the AV-HDD, to take the initiative in the market. This paper describes the state of plastic medium development, which is regarded as a next-generation strategic commodity. (author)

    Tang, Hsin-Yi Jean; Riegel, Barbara; McCurry, Susan M; Vitiello, Michael V

    2016-03-01

    Audio Visual Stimulation (AVS), a form of neurofeedback, is a non-pharmacological intervention that has been used for both performance enhancement and symptom management. We review the history of AVS, its two sub-types (close- and open-loop), and discuss its clinical implications. We also describe a promising new application of AVS to improve sleep, and potentially decrease pain. AVS research can be traced back to the late 1800s. AVS's efficacy has been demonstrated for both performance enhancement and symptom management. Although AVS is commonly used in clinical settings, there is limited literature evaluating clinical outcomes and mechanisms of action. One of the challenges to AVS research is the lack of standardized terms, which makes systematic review and literature consolidation difficult. Future studies using AVS as an intervention should; (1) use operational definitions that are consistent with the existing literature, such as AVS, Audio-visual Entrainment, or Light and Sound Stimulation, (2) provide a clear rationale for the chosen training frequency modality, (3) use a randomized controlled design, and (4) follow the Consolidated Standards of Reporting Trials and/or related guidelines when disseminating results.

    NASA's Dawn spacecraft arrived at the asteroid 4 Vesta in July 2011 and is now collecting imaging and spectroscopic data during its one-year orbital mission. The maps we present are based on information obtained by the Visible and Infrared Mapping Spectrometer VIR-MS and the multi-color Framing Camera FC. VIR covers the wavelength range between 0.25 to 5.1 µm while FC covers the range 0.4 to 1.0 µm. The VIR instrument has a significant higher spectral resolution than FC but the latter achieves higher spatial resolution data. As part of the geological and mineralogical analysis of the surface, a series of 15 quadrangles have been defined covering the entire surface of Vesta. We report about the mapping results of quadrangle Av-6 (Gegania) and Av-7 (Lucaria). The Gegania quadrangle is dominated by old craters showing no ejecta blankets and rays while several small fresh craters do. The most obvious geologic features are a set of equatorial troughs, a group of three ghost craters of similar diameter (~57 km), an ejecta mantling of the Gegania crater and three smaller craters showing bright and dark ejecta rays. The quadrangle contains two main geologic units: 1) the northern cratered trough terrain and 2) the equatorial ridge and trough terrain. The quadrangle shows moderate variation in Band II center wavelength and Band II depth. FC color ratio variations of some recent craters and their ejecta are linked to the bright and dark material. The bright material is possibly excavated eucritic material while the dark material could be remnants of a CM2 impator(s) or an excavated subsurface layer of endogenic origin. The most prominent geologic features in the Lucaria quadrangle are the 40 km long hill Lucaria Tholus, a set of equatorial troughs, some relatively fresh craters with bright and dark material and mass wasting. The quadrangle contains three main geologic units: 1) the northern cratered trough terrain, 2) the equatorial ridge and trough terrain, and 3) the

    Junctional ectopic tachycardia (JET) is a postoperative complication with a mortality rate of up to 14% after surgery for congenital heart disease. This study evaluated the risk factors of JET and explored the association of postoperative temporary third degree atrioventricular (AV) block and the occurrence of JET. Data were collected retrospectively from 1158 patients who underwent surgery for congenital heart disease. The overall incidence of JET was 2.8%. Temporary third degree AV block occurred in 1.6% of cases. Permanent third degree AV block requiring pacemaker implantation occurred in 1% of cases. In all, 56% of patients with JET had temporary AV block (P < 0.001), whereas no case of postoperative JET was reported in patients with permanent AV block (P = 0.56). temporary third degree AV block did not suffer from JET. A correlation between temporary third degree AV block and postoperative JET could be observed. The risk factors identified for JET include younger age groups at the time of surgery, longer aortic cross clamping time and surgical procedures in proximity to the AV node

    The federal government advocates the practice of routinely providing an after-visit summary (AVS) to patients after each office-based visit as an element of stage 1 meaningful use. A significant potential benefit of the AVS is improved patient engagement achieved by enabling patients and family members to better understand and retain key health information. The methodology for this study was a mixed-methods pilot study to examine, through the perspectives of adult primary care patients, how relevant and actionable data can be better formatted in the AVS. Results of this study suggest that the goal of the AVS to serve as a communication tool to engage and support patients is frequently not being met. Further study is needed to understand, from the viewpoints of patients and providers, what barriers are keeping them from optimally providing and using the information on the AVS.

    Full Text Available Det er en utbredt oppfatning at det økende prestasjonskravet i toppfotball fører til en svekkelse av moral og fair play-holdninger. Men hvordan tenker toppfotballspillere i forhold til ulike dilemmaer som oppstår på banen, og er det forskjeller mellom toppfotballspillere og spillere på lavere nivå?  For å avklare dette gjennomførte vi en empirisk undersøkelse der vi intervjuet spillere og trener i én toppklubb og én breddeklubb. Vi var interessert i to hovedproblemstillinger:  1 Hva tenker fotballspillere på ulike prestasjonsnivå om etikk og moralske dilemmaer i fotball? 2 Hvilke faktorer påvirker spillerne, direkte og indirekte, i deres vurderinger og handlinger? Resultatene fra undersøkelsen viser at det er store forskjeller mellom de to prestasjonsnivåene. Spillerne på breddenivået føler generelt et større ansvar for å opptre ærlig på banen enn hva som er tilfelle på toppnivået. Vi fant 4 spesifikke faktorer i toppfotballen som bidrar til umoralsk opptreden. For det første opplever spillerne en forventning om at de prioriterer resultat foran fair play.

    Full Text Available Vurdering av andrespråkselevers språkkompetanse og språkutvikling er en sentral del av læreres arbeid, og forskning har vist at dette er en utfordring for skolene. Det er stor variasjon i vurderingsformer, og skolene mangler ofte vurderingskompetanse. På bakgrunn av dette utarbeidet Utdanningsdirektoratet i 2007 vurderingsverktøyet Kartleggingsmateriell. Språkkompetanse i grunnleggende norsk for språklige minoriteter. Materiellet er utarbeidet blant annet med referanse til Common European Framework of Reference for Languages (CEFR. I artikkelen redegjør vi for en undersøkelse der målet var å finne ut hvorvidt dette kartleggingsmateriellet er hensiktsmessig for å vurdere andrespråkselevers språkkompetanse. Hoveddataene er innhentet gjennom kasusstudier ved tre grunnskoler, der vi intervjuet skoleledelse og lærere samt observerte kartleggingssituasjoner og klasseromsundervisning. Kasusstudiene ble senere fulgt opp av to spørreundersøkelser, én til de samme skolene, og én til et større antall skoler for å få bredere innsikt i kartleggingspraksis og skolers oppfatninger av denne formen for vurdering. Undersøkelsen viser at flere av informantene mener verktøyet kan bidra til mer tilpasset og systematisk andrespråkopplæring og bedre vurdering av andrespråkselevenes språkkompetanse. Samtidig er det utfordringer knyttet til å bruke vurderingsverktøyet, dette skyldes blant annet mangelfull kompetanse i skolen når det gjelder andrespråkstilegnelse og vurdering av elevenes språkkompetanse. Det er ikke tidligere forsket på bruk av et slikt konkret kartleggingsverktøy i norsk grunnskole. Undersøkelsen kan gi et bidrag til økt kunnskap om vurdering av andrespråkskompetanse og tilpasset undervisning for andrespråksinnlærere.

    Sediment treatment and sediment storage may alter sediment toxicity, and consequently biotic response. Purpose of our study was to combine these three aspects (treatment-toxicity-biotic response) in one integrated approach. We used Acid Volatile Sulfide (AVS) concentrations as a proxy of the disturbance of the sediment. AVS and Simultaneously Extracted Metal (SEM) concentrations were compared to bioassay responses with the freshwater benthic macroinvertebrate Asellus aquaticus. Storage conditions and sediment treatment affected AVS but not SEM levels. AVS can be used as a proxy for sediment disturbance. The best way to pretreat the sediment for use in a bioassay in order to maintain initial AVS conditions was to sample the sediment with an Ekman grab, immediately store it in a jar without headspace, and freeze it as soon as possible. In a survey using seven different sediments, bioassay responses of A. aquaticus were correlated with SEM and AVS characteristics. - Change in AVS is a good proxy for sediment disturbance and combined with SEM it can be used as a suitable predictor for biotic effects of sediment contamination.

    Full Text Available  SAMMENDRAGLangsom vektøkning gjennom livet inntil kroppsmasseindeks (KMI 27 ser ikke ut til å gi særlige negative utfallmht. total dødelighet. En økning på ! 20 kg fra 18 års alder er trolig negativt – det samme er vektøkning ut fra enhøy utgangsvekt. Selv om mange studier finner økt dødelighet hos yngre og middelaldrende personer med KMI > 27,er det foreløpig ingen studier som har vist at vektreduksjon blant friske overvektige personer gir økt levetid. Flerestudier viser tvert imot en assosiasjon mellom vektreduksjon og økt dødelighet. Heller ikke studier som prøver åbegrense analysene til personer med frivillig vekttap, finner redusert dødelighet etter vektreduksjon blant friskeovervektige individer. Noen få studier har vist redusert dødelighet blant overvektige personer med etablertesykdommer eller høy risiko for hjerte-karsykdom og diabetes. Når det gjelder sykelighet har de fleste studier entenikke funnet noen assosiasjon mellom vektreduksjon og sykelighet, eller funnet økt sykelighet. Unntaket er diabetes,der vekttap i enkelte studier samvarierer med redusert sykelighet. Det er i mange studier funnet sammenheng mellomvekttap og økt risiko for lårhalsbrudd og gallesten. De fleste studier har imidlertid vist at moderat vektreduksjon(vekttap på opp til 10% fører til redusert blodtrykk, forbedret glukosekontroll, redusert kolesterolnivå, forbedretdyslipidemi, forbedret lungefunksjon, bedre søvnkvalitet og redusert søvnapnè. Moderat vekttap vil også kunnelindre leddsmerter. Dette tilsynelatende paradoks diskuteres i artikkelen – bl.a. drøftes de metodeproblemer som erinnebygget i mange av studiene. Fordi det har vist seg vanskelig for personer med kraftig overvekt å redusere vektenpermanent – og fordi resultatene mht. helseeffektene av vektreduksjon er usikre, bør hovedinnsatsen settes inn iforhold til å forebygge overvekt/fedme overfor enkeltpersoner med potensielle problemer.

    One novel styrylpyridine derivatives(AV-45) coupled with 99m Tc complex was synthesized. 99m Tc-BAT-AV-45 was prepared by a ligand exchange reaction employing sodium glucoheptonate, and effects of the amount of ligand, stannous chloride, sodium glucoheptonate and pH value of reaction mixture on the radiolabeling yield were studied in details. Quality control was performed by thin layer chromatography and high performance liquid chromatography. Besides the stability, partition coefficient and electrophoresis of 99m Tc-BAT-AV-45 were also investigated. The results showed that the average radiolabeling yield was (95 ± 1%) and 99m Tc-BAT-AV-45 with suitable lipophilicity was stable and uncharged at physiological pH. (author)

    Morphine-induced glial proinflammatory responses have been documented to contribute to tolerance to opioid analgesia. Here, we examined whether drugs previously shown to suppress glial proinflammatory responses can alter other clinically relevant opioid effects; namely, withdrawal or acute analgesia. AV411 (ibudilast) and minocycline, drugs with distinct mechanisms of action that result in attenuation of glial proinflammatory responses, each reduced naloxone-precipitated withdrawal. Analysis of brain nuclei associated with opioid withdrawal revealed that morphine altered expression of glial activation markers, cytokines, chemokines, and a neurotrophic factor. AV411 attenuated many of these morphine-induced effects. AV411 also protected against spontaneous withdrawal-induced hyperactivity and weight loss recorded across a 12-day timecourse. Notably, in the spontaneous withdrawal study, AV411 treatment was delayed relative to the start of the morphine regimen so to also test whether AV411 could still be effective in the face of established morphine dependence, which it was. AV411 did not simply attenuate all opioid effects, as co-administering AV411 with morphine or oxycodone caused three-to-five-fold increases in acute analgesic potency, as revealed by leftward shifts in the analgesic dose response curves. Timecourse analyses revealed that plasma morphine levels were not altered by AV411, suggestive that potentiated analgesia was not simply due to prolongation of morphine exposure or increased plasma concentrations. These data support and extend similar potentiation of acute opioid analgesia by minocycline, again providing converging lines of evidence of glial involvement. Hence, suppression of glial proinflammatory responses can significantly reduce opioid withdrawal, while improving analgesia.

    The limitations of manned airborne meteorological measurements led to a new unmanned system, the Meteorological Mini-UAV (M{sup 2}AV), recently developed by the Institute of Aerospace Systems, Technical University of Braunschweig. The task was to develop, test and verify a meteorological sensor package as payload for an already available carrier aircraft, the UAV 'Carolo T200'. Thereby the limitations in size and mass had to be respected. The M{sup 2}AV is capable of performing turbulence and wind vector measurements within the atmospheric boundary layer and permits very short measurement cycles as an economic supplement during meteorological campaigns. The article gives details on the technical items. Results from meteorological data sets measured by the M{sup 2}AV are used for data quality assessment. In October 2005 the M{sup 2}AV participated in the meteorological field experiment 'LAUNCH 2005' in Lindenberg near Berlin. The M{sup 2}AV data were compared with lidar and sodar/RASS measurements. Furthermore, an in situ comparison of temperature, humidity and wind vector data with the helicopter-borne turbulence probe Helipod was analysed and gave information about the M{sup 2}AV data quality.

Among several candidate epigenetic mechanisms, DNA methylation may play an important role in the etiology of CHDs. We conducted a genome-wide DNA methylation analysis using an Illumina Infinium 450k human methylation assay in a cohort of 24 newborns who had aortic valve stenosis (AVS, with gestational-age matched controls. The study identified significantly-altered CpG methylation at 59 sites in 52 genes in AVS subjects as compared to controls (either hypermethylated or demethylated. Gene Ontology analysis identified biological processes and functions for these genes including positive regulation of receptor-mediated endocytosis. Consistent with prior clinical data, the molecular function categories as determined using DAVID identified low-density lipoprotein receptor binding, lipoprotein receptor binding and identical protein binding to be over-represented in the AVS group. A significant epigenetic change in the APOA5 and PCSK9 genes known to be involved in AVS was also observed. A large number CpG methylation sites individually demonstrated good to excellent diagnostic accuracy for the prediction of AVS status, thus raising possibility of molecular screening markers for this disorder. Using epigenetic analysis we were able to identify genes significantly involved in the pathogenesis of AVS.

    2009-01-01

    Adrenal venous sampling (AVS) is the criterion standard to distinguish between unilateral and bilateral adrenal disease in patients with primary aldosteronism. The keys to successful AVS include appropriate patient selection, careful patient preparation, focused technical expertise, defined protocol, and accurate data interpretation. The use of AVS should be based on patient preferences, patient age, clinical comorbidities, and the clinical probability of finding an aldosterone-producing adenoma. AVS is optimally performed in the fasting state in the morning. AVS is an intricate procedure because the right adrenal vein is small and may be difficult to locate - the success rate depends on the proficiency of the angiographer. The key factors that determine the successful catheterization of both adrenal veins are experience, dedication and repetition. With experience, and focusing the expertise to 1 or 2 radiologists at a referral centre, the AVS success rate can be as high as 96%. A centre-specific, written protocol is mandatory. The protocol should be developed by an interested group of endocrinologists, radiologists and laboratory personnel. Safeguards should be in place to prevent mislabelling of the blood tubes in the radiology suite and to prevent sample mix-up in the laboratory.

    Neurons from the rostral ventrolateral medulla (RVLM) directly activate sympathetic pre-ganglionic neurons in the spinal cord. Hypertensive responses and sympathetic activation produced by different stimuli are strongly affected by lesions of the preoptic periventricular tissue surrounding the anteroventral third ventricle (AV3V region). Therefore, in the present study, we investigated the effects of acute (1 day) and chronic (15 days) electrolytic lesions of the AV3V region on the pressor responses produced by injections of the excitatory amino acid L-glutamate into the RVLM of unanesthetized rats. Male Holtzman rats with sham or electrolytic AV3V lesions and a stainless steel cannula implanted into the RVLM were used. The pressor responses produced by injections of L-glutamate (1, 5 and 10 nmol/100 nl) into the RVLM were reduced 1 day (9 +/- 4, 39 +/- 6 and 37 +/- 4 mm Hg, respectively) and 15 days after AV3V lesions (13 +/- 6, 39 +/- 4 and 43 +/- 4 mm Hg, respectively, vs. sham lesions: 29 +/- 3, 50 +/- 2 and 58 +/- 3 mm Hg, respectively). Injections of L-glutamate into the RVLM in sham or AV3V-lesioned rats produced no significant change in the heart rate (HR). Baroreflex bradycardia and tachycardia produced by iv phenylephrine or sodium nitroprusside, respectively, and the pressor and bradycardic responses to chemoreflex activation with iv potassium cyanide were not modified by AV3V lesions. The results suggest that signals from the AV3V region are important for sympathetic activation induced by L-glutamate into the RVLM.

    2017-05-01

    SL-AV (semi-Lagrangian, based on the absolute vorticity equation) is a global hydrostatic atmospheric model. Its latest version, SL-AV20, provides global operational medium-range weather forecast with 20 km resolution over Russia. The lower-resolution configurations of SL-AV20 are being tested for seasonal prediction and climate modeling. The article presents the model dynamical core. Its main features are a vorticity-divergence formulation at the unstaggered grid, high-order finite-difference approximations, semi-Lagrangian semi-implicit discretization and the reduced latitude-longitude grid with variable resolution in latitude. The accuracy of SL-AV20 numerical solutions using a reduced lat-lon grid and the variable resolution in latitude is tested with two idealized test cases. Accuracy and stability of SL-AV20 in the presence of the orography forcing are tested using the mountain-induced Rossby wave test case. The results of all three tests are in good agreement with other published model solutions. It is shown that the use of the reduced grid does not significantly affect the accuracy up to the 25 % reduction in the number of grid points with respect to the regular grid. Variable resolution in latitude allows us to improve the accuracy of a solution in the region of interest.

    2013-01-01

    The mechanism of bacterial resistance to tributyltin (TBT) is still unclear. The results herein presented contribute to clarify that mechanism in the TBT-resistant bacterium Aeromonas molluscorum Av27. We have identified and cloned a new gene that is involved in TBT resistance in this strain. The gene is highly homologous (84%) to the Aeromonas hydrophila-sugE gene belonging to the small multidrug resistance gene family (SMR), which includes genes involved in the transport of lipophilic drugs. In Av27, expression of the Av27-sugE was observed at the early logarithmic growth phase in the presence of a high TBT concentration (500 μM), thus suggesting the contribution of this gene for TBT resistance. E. coli cells transformed with Av27-sugE become resistant to ethidium bromide (EtBr), chloramphenicol (CP) and tetracycline (TE), besides TBT. According to the Moriguchi logP (miLogP) values, EtBr, CP and TE have similar properties and are substrates for the sugE-efflux system. Despite the different miLogP of TBT, E. coli cells transformed with Av27-sugE become resistant to this compound. So it seems that TBT is also a substrate for the SugE protein. The modelling studies performed also support this hypothesis. The data herein presented clearly indicate that sugE is involved in TBT resistance of this bacterium.

    Energy-derived waters containing naphthenic acids (NAs) are complex mixtures often comprising a suite of potentially problematic constituents (e.g. organics, metals, and metalloids) that need treatment prior to beneficial use, including release to receiving aquatic systems. It has previously been suggested that NAs can have biostatic or biocidal properties that could inhibit microbially driven processes (e.g. dissimilatory sulfate reduction) used to transfer or transform metals in passive treatment systems (i.e. constructed wetlands). The overall objective of this study was to measure the effects of a commercially available (Fluka) NA on sulfate-reducing bacteria (SRB), production of sulfides (as acid-volatile sulfides [AVS]), and precipitation of divalent metals (i.e. Cu, Ni, Zn).

    Permanent AV-block is a recognized and feared complication of slow pathway modulation for AVNRT. We aimed to assess incidence of transient and permanent AV-block as well as consequences of transient AV-block in a large contemporary AVNRT ablation cohort. We searched our single center prospective ablation database for occurrence of transient and permanent AV-block during slow pathway modulation between January 2004 and October 2015. We analyzed patients' and procedural characteristics as well as outcome of patients in whom transient or permanent AV-block occurred. Of 9170 patients who underwent a catheter ablation at our institution between January 2004 and October 2015, 2101 patients (64% women, mean age 50±18years) underwent slow pathway modulation. In three patients, permanent AV-block occurred during RF application. Additional two patients had transient AV-block that recovered (after a few minutes and 25min), but recurred within two days of the procedure. All five patients underwent dual chamber pacemaker implantation (0.2%). Transient AV-block related to RF delivery occurred in 44 patients (2%). Transient mechanical AV-block occurred in additional 17 patients (0.8%). In 12 patients, ablation was continued despite transient AV-block. One of these patients developed permanent AV-block. Permanent AV-block following slow pathway modulation is a rare event, occurring in 0.2% of patients in a large contemporary single center cohort. Transient AV-block is more frequent (2%).

  17. Forholdet mellom stat og kommune i styring av norsk utdanningspolitikk 1970 - 2008

    Directory of Open Access Journals (Sweden)

    Øystein Engeland

    2009-06-01

    Full Text Available Denne artikkelen er skrevet ut fra en antakelse om at norsk utdanningsforvaltning etter 1990 illustrerer forsøk på å styrke den statlige forvaltning innen et desentralisert system. Ikke minst er dette tydelig ved at nasjonal styring av utdanning særlig etter århundreskiftet har økt på bekostning av det lokale selvstyret. I forhold til maktfordelingen mellom staten og kommunene er vi nå nærmest tilbake til situasjonen før den politiske desentraliseringsbølgen startet mot slutten av 1970-tallet. Det nasjonale nivået er i ferd med å etablere et styringsgrep på skolesiden som er så omfattende at det mangler sidestykke i moderne tid. Det nye er at dette skjer innen et system hvor inntektssystemet (1986 gir kommunene ansvar for undervisningen, og hvor statens mulighet til å bruke økonomiske styringsmidler er redusert.

  20. The parsec-scale relationship between ICO and AV in local molecular clouds

    Science.gov (United States)

    Lee, Cheoljong; Leroy, Adam K.; Bolatto, Alberto D.; Glover, Simon C. O.; Indebetouw, Remy; Sandstrom, Karin; Schruba, Andreas

    2018-03-01

    We measure the parsec-scale relationship between integrated CO intensity (ICO) and visual extinction (AV) in 24 local molecular clouds using maps of CO emission and dust optical depth from Planck. This relationship informs our understanding of CO emission across environments, but clean Milky Way measurements remain scarce. We find uniform ICO for a given AV, with the results bracketed by previous studies of the Pipe and Perseus clouds. Our measured ICO-AV relation broadly agrees with the standard Galactic CO-to-H2 conversion factor, the relation found for the Magellanic clouds at coarser resolution, and numerical simulations by Glover & Clark (2016). This supports the idea that CO emission primarily depends on shielding, which protects molecules from dissociating radiation. Evidence for CO saturation at high AV and a threshold for CO emission at low AV varies remains uncertain due to insufficient resolution and ambiguities in background subtraction. Resolution of order 0.1 pc may be required to measure these features. We use this ICO-AV relation to predict how the CO-to-H2 conversion factor (XCO) would change if the Solar Neighbourhood clouds had different dust-to-gas ratio (metallicity). The calculations highlight the need for improved observations of the CO emission threshold and H I shielding layer depth. They are also sensitive to the shape of the column density distribution. Because local clouds collectively show a self-similar distribution, we predict a shallow metallicity dependence for XCO down to a few tenths of solar metallicity. However, our calculations also imply dramatic variations in cloud-to-cloud XCO at subsolar metallicity.

    Full Text Available The multiple sorption of sodium tungstate resulting from the autoclave-soda digestion of a tungsten-bearing concentrate was studied using anion-exchange resin AV-17-8. The choice of ion exchange resin was carried out under static conditions using highly basic anionites. The sorption and desorption plots for tungstate and carbonate ions were demonstrated under dynamic conditions. The total dynamic capacity of the resin was estimated for each species of the ions in three sorption cycles. The applicability of the AV-17-8 resin as a sorbent in the autoclave-soda process flowsheet was determined.

  10. Betydningen av drektige reinsimlers ernæring for kalvers vekst, klimatiske toleranse og overlevelse

    Directory of Open Access Journals (Sweden)

    Arne Rognmo

    2013-03-01

    Full Text Available Forsøkene (viste at tilleggsforing av underernærte simler i siste del av drektighetsperioden kun synes å ha effekt på fødselsvekten for kalvene forutsatt at simlene får høyverdig ernæring etter kalving. Den forskjellige ernæringsbakgrunn før kalving synes således ikke å innvirke på melkeproduksjon/kvalitet, da vektutviklingen for alle grupper av kalver i dette forsøket gikk parallelt i de tre første ukene etter kalving. Det ble heller ikke på noe punkt funnet signifikante forskjeller gruppene imellom når det gjelder kalvenes klimatiske toleranse. Det er dog bemerkelsesverdig at det var stor dødelighet blant de små kalvene etter unge små simler i GRUPPE L. Dette funn er interessant sett i sammenheng med resultatene fra Røros (se bidrag fra Dag Lenvik, side som viser at avkastningen fra en flokk kan økes markant om man konsentrerte slakteuttaket på små kalver og forhindrer bedekning av små, unge simler gjennom fjerning av eldre, store bukker. Med det forbehold at våre forsøk er utført på dyr i innhegning med et lavt aktivitetsnivå, kan man fra våreforsøk foreløpig konkludere med at tillegsfor ing av simler i siste halvdel av drektighetsperioden har effekt på kalvenes fødselsvekt, men at vektutviklingen for kalven er uavhengig av simlenes ernæringshistorie, om sistnevnte tilbys høyverdig ernæring etter kalving. Da små kalver etter underernærte simler viste høy dødelighet like etter fødselen, vil imidlertid tilleggsforing kunne øke avkastningen om det er mange unge simler i flokken. Resultatene fra Røros tyder imidlertid på at dette resultat normalt kan oppnås uten ekstra omkostninger gjennom et selektivt slakteuttak.

Det er derfor av interesse å undersøke nærmere hvordan nyutdannede lærere opplever både sin fagkunnskap og nyervervede kompetanse i yrket. Undersøkelsen som her blir presentert har følgende problemstilling: Hvordan opplever nyutdannede lærere sin kompetanse i leseopplæring generelt og leseopplæring av elever med lesevansker spesielt? Denne pilotundersøkelsen tar utgangspunkt i Q- metoden; nyutdannede lærere plasserer subjektive utsagn trykt på individuelle kort i en matrise. Pilotundersøkelsen baserer seg på 10 respondenter, vi valgte derfor en kvalitativ analyse av resultatene av Q-sorteringen. Resultatene viser at nyutdannede lærere opplever at de mangler kunnskap og kompetanse både i praktisk leseopplæring generelt og om lesevansker spesielt. Kartleggingsmateriell blir i liten grad brukt som grunnlag for informantenes tilrettelegging av arbeidsmåter i leseopplæring. Inkludering og sammenholdte klasser står sterkt hos informantene, men de savner informasjon om elever med lesevansker og om tilgjengelig hjelpemateriell.

  17. Diphenylhydantoin and lidocaine modification of A-V conduction in halothane-anesthetized dogs.

    Science.gov (United States)

    Atlee, J L; Homer, L D; Tobey, R E

    1975-07-01

    The effect of halothane on A-V conduction was evaluated in gods during atrial pacing using the technique of His-bundle electrocardiography. In addition, the effects of lidocaine and diphenylkydantoin (DPH) on A-V conuction were examined during halothane anesthesia. Effects of these drugs on three subintervals of A-V conduction were compared. These included the -H (stimulus atifact of His-bundle deflection-atrioventricular conduction), H-Q (His-budnle deflection onset of QRS complex-His-Purkinje conduction), and H-S intervals(His-bundle delfection to end of QRS COmplex-total intraventricular conduction). Linear regression best described the relationship between duration of interval (P-H, H-V,and H-S) and heart rate during incremental increases in the atrial paced rate. Data from these experiments were fitted to a multiple lenear regression model that predicted the effect of increasing concentrations of halothan, lidocaine, and DPH on slope and intercept coefficients. In creasing concentrations of halothan ( 30 and 45 mg/100 ml arterial). Both lidocaine and DPH further depressed conduction at all levels of halothan anesthesia. The P-H interval was particularly sensitive todrug effefts. This may represent potentiation of the normal slowing of conduction through the AVnode in response to incremental increases in heart rate (fatigue response.) We conclude thatboth lidocaine and DPH fail to reverse the depressant effect of halothane on A-V conduction. This may explain their ineffectiveness in treating certain types of arrhythmias during halothane anesthesia.

    2009-04-01

    In risk assessment of aquatic sediments, much attention is paid to the difference between acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) as indicators of metal availability. Ten representative sampling sites were selected along the estuary of the Guadalete River. Surficial sediments were sampled in winter and summer to better understand SEM and AVS spatial and seasonal distributions and to establish priority risk areas. Total SEM concentration (SigmaSEM) ranged from 0.3 to 4.7 micromol g(-1). It was not significantly different between seasons, however, it showed a significant difference between sampling stations. AVS concentrations were much more variable, showing significant spatial and temporal variations. The values ranged from 0.8 to 22.4 micromol g(-1). The SEM/AVS ratio was found to be <1 at all except one station located near the mouth of the estuary. The results provided information on a potential pollution source near the mouth of the estuary, probably associated with vessel-related activities carried out in a local harbor area located near the station.

    Retinoic acid receptor-related orphan receptor-α (RORα) (NR1F1) is an orphan nuclear receptor with a potential role in metabolism. Previous studies have shown that RORα regulates transcription of the murine Apolipoprotein AI gene and human Apolipoprotein CIII genes. In the present study, we present evidence that RORα also induces transcription of the human Apolipoprotein AV gene, a recently identified apolipoprotein associated with triglyceride levels. Adenovirus-mediated overexpression of RORα increased the endogenous expression of ApoAV in HepG2 cells and RORα also enhanced the activity of an ApoAV promoter construct in transiently transfected HepG2 cells. Deletion and mutation studies identified three AGGTCA motifs in the ApoAV promoter that mediate RORα transactivation, one of which overlaps with a previously identified binding site for PPARα. Together, these results suggest a novel mechanism whereby RORα modulates lipid metabolism and implies RORα as a potential target for the treatment of dyslipidemia and atherosclerosis

    As part of the Dawn's orbital mapping investigation of Vesta, the Science Team is conducting geologic mapping of the surface in the form of 15 quadrangle maps, including quadrangle Av-11 (Pinaria). The base map is a monochrome Framing Camera (FC) mosaic at ~70 m/pixel, supplemented by Digital Terrain Models (DTM) and FC color ratio images, both at ~250 m/pixel, slope and contour maps, and Visible and Infrared (VIR) hyperspectral images. Av-11 straddles the 45-degree longitude in the South Polar Region, and is dominated by the rim of the ~505 km south polar topographic feature, Rheasilvia. Sparsely cratered (relatively), Av-11 is dominated by a 20 km high rim scarp (Matronalia Rupes) and by arcuate ridges and troughs forming a radial to spiral pattern across the basin floor. Primary geologic features of Av-11 include the following. Ridge-and-groove terrain radiating arcuately from the central mound unit, interpreted to be structural disruption of the basin floor associated with basin formation. The largest crater in Av-11 is Pinaria (37 km). Mass wasting deposits are observed on its floor. Secondary crater chains and fields are also evident. Mass wasting observed along Rheasilvia rim scarp and in the largest craters indicates scarp failure is a significant process. Parallel fault scarps mark this deposit of slumped debris at the base of 20 km high Matronalia Rupes, which may have formed during or shortly after basin excavation. We interpret most of these deposits as slump material emplaced as a result of the effects of basin formation and collapse. Lobate materials are characterized by lineations and lobate scarps and interpreted as Rheasilvia ejecta deposit outside Rheasilvia rim (the smoothest terrain on Vesta), and are consistent with formation by ejecta. Partial burial of older craters near the edge of these deposits are also observed.

    Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people. By screening PubMed, Google Scholar, Scopus and JSTOR, fifteen cases were found of which eight were sufficiently documented for full analysis. Blood alcohol levels ranged from 90 to 958 mg/dl (19 to 205 mM). Second and third degree AV block was observed most (6/8) albeit that in two of these patients a vagal stimulus led to deterioration from first into higher order AV block. In all cases, patients reverted to normal sinus rhythm upon becoming sober again. Mildly lowered body temperature (35.9 ± 0.5°C) was observed but can be excluded as a major cause of conduction blockade. We hypothesize that ethanol induced partial inhibition of calcium and potentially also sodium currents in conductive tissue structures may be one of the mechanisms of conduction slowing and block that may become exaggerated upon increased vagal tone. An impairment of gap junction function cannot be excluded as a contributing factor. In conclusion, cases of documented alcohol induced AV block are very rare but events can occur at relatively low serum alcohol levels which should prompt to awareness of this phenomenon in alcohol intoxicated patients.

    Defensins are frontline peptides of mucosal immunity in the animal kingdom, including birds. Their resistance to proteolysis and their ensuing ability to maintain antimicrobial potential remains questionable and was therefore investigated. We have shown by bottom-up mass spectrometry analysis of protein extracts that both avian beta-defensins AvBD2 and AvBD7 were ubiquitously distributed along the chicken gut. Cathepsin B was found by immunoblotting in jejunum, ileum, caecum, and caecal tonsils, while cathepsins K, L, and S were merely identified in caecal tonsils. Hydrolysis product of AvBD2 and AvBD7 incubated with a panel of proteases was analysed by RP-HPLC, mass spectrometry and antimicrobial assays. AvBD2 and AvBD7 were resistant to serine proteases and to cathepsins D and H. Conversely cysteine cathepsins B, K, L, and S degraded AvBD2 and abolished its antibacterial activity. Only cathepsin K cleaved AvBD7 and released Ile4-AvBD7, a N-terminal truncated natural peptidoform of AvBD7 that displayed antibacterial activity. Besides the 3-stranded antiparallel beta-sheet typical of beta-defensins, structural analysis of AvBD7 by two-dimensional NMR spectroscopy highlighted the restricted accessibility of the C-terminus embedded by the N-terminal region and gave a formal evidence of a salt bridge (Asp9-Arg12) that could account for proteolysis resistance. The differential susceptibility of avian defensins to proteolysis opens intriguing questions about a distinctive role in the mucosal immunity against pathogen invasion.

    Av3, a neurotoxin of Anemonia viridis, is toxic to crustaceans and cockroaches but inactive in mammals. In the present study, Av3 was expressed in Escherichia coli Origami B (DE3) and purified by reversed-phase liquid chromatography. The purified Av3 was injected into the hemocoel of Helicoverpa armigera, rendering the worm paralyzed. Then, Av3 was expressed alone or fusion expressed with the Cry1Ac in acrystalliferous strain Cry(-)B of Bacillus thuringiensis. The shape of Cry1Ac was changed by fusion with Av3. The expressed fusion protein, Cry1AcAv3, formed irregular rhombus- or crescent-shaped crystalline inclusions, which is quite different from the shape of original Cry1Ac crystals. The toxicity of Cry1Ac was improved by fused expression. Compared with original Cry1Ac expressed in Cry(-)B, the oral toxicity of Cry1AcAv3 to H. armigera was elevated about 2.6-fold. No toxicity was detected when Av3 was expressed in Cry(-)B alone. The present study confirmed that marine toxins could be used in bio-control and implied that fused expression with other insecticidal proteins could be an efficient way for their application.

    2016-12-01

    The AV-reentrant tachycardia (AVRT) is a supraventricular tachycardia with an incidence of 1-3/1000. The pathophysiological basis is an accessory atrioventricular pathway (AP). Patients with AVRT typically present with palpitations, an on-off characteristic, anxiety, dyspnea, and polyuria. This type of tachycardia may often be terminated by vagal maneuvers. Although the clinical presentation of AVRT is quite similar to AV-nodal reentrant tachycardias, the correct diagnosis is often facilitated by analyzing a standard 12-lead ECG at normal heart rate showing ventricular preexcitation. Curative catheter ablation of the AP represents the therapy of choice in symptomatic patients. This article is the fourth part of a series written to improve the professional education of young electrophysiologists. It explains pathophysiology, symptoms, and electrophysiological findings of an invasive EP study. It focusses on mapping and ablation of accessory pathways.

    Full Text Available Hensikten med denne studien er å studere hvordan 15-åringer opplever overvekt hos jevnaldrende. Datamaterialet består av dybdeintervju med syv ungdommer. Det er benyttet fenomenologisk-hermeneutisk analyse. Ungdommene opplever å stå i en posisjon mellom makt og avmakt. I denne mellomposisjonen framkommer det at ungdommene distanserer seg ved hjelp av relasjonell makt, men samtidig setter de seg selv i en avmaktssituasjon i forhold til ungdomskulturens spilleregler. Ungdommene moraliserer ved å skape en situasjon hvor de underkjenner overvektige, samtidig mangler de ytterligere sanksjoneringsmuligheter. Rangordninger skapes gjennom at ungdommene degraderer overvektige, men de må selv også innordne seg i egen kultur. Ungdommene fratar overvektige sitt menneskeverd gjennom å redusere menneskelige egenskaper og gjør dem til objekt. Gjennom denne objektiviseringen setter de seg selv utenfor det å få tak i overvektiges refleksjons- og erfaringsgrunnlag.

    {sup 18}F-Florbetapir (AV-45/Amyvid) is a novel positron emission tomography (PET) tracer for imaging plaque pathology in Alzheimer's disease (AD), while PET images of fluorodeoxyglucose (FDG) for cerebral glucose metabolism can provide complementary information to amyloid plaque images for diagnosis of AD. The goal of this preliminary study was to investigate the perfusion-like property of relative cerebral blood flow estimates (R{sub 1}) and summed early-phase AV-45 images [perfusion AV-45 (pAV-45)] and optimize the early time frame for pAV-45. Dynamic AV-45 PET scans (0-180 min) were performed in seven subjects. pAV-45, late-phase AV-45, and FDG images were spatially normalized to the Montreal Neurological Institute template aided by individual MRI images, and the corresponding standardized uptake value ratio (SUVR) was computed. The R{sub 1} images were derived from a simplified reference tissue model. Correlations between regional and voxelwise R{sub 1} and the corresponding FDG images were calculated. An optimization of time frames of pAV-45 was conducted in terms of correlation to FDG images. The optimal early time frame was validated in a separate cohort. The regional distribution in the R{sub 1} images correlated well (R = 0.91) to that of the FDG within subjects. Consistently high correlation was noted across a long range of time frames. The maximal correlation of pAV-45 to FDG SUVR of R = 0.95 was observed at the time frame of 1-6 min, while the peak correlation of R = 0.99 happened at 0-2 min between pAV-45 and R{sub 1}. A similar result was achieved in the validation cohort. Preliminary results showed that the distribution patterns of R{sub 1} and pAV-45 images are highly correlated with normalized FDG images, and the initial 5-min early time frame of 1-6 min is potentially useful in providing complementary FDG-like information to the amyloid plaque density by late-phase AV-45 images.

    Full Text Available Språkkartlegging i barnehagen er et konfliktfylt felt som preges av enten/eller tenkning. På den ene siden ser kartleggingstilhengerne ut til å ha en positivistisk tro på at kartlegging kan bidra til løsninger på alt fra enkeltbarns behov for hjelp, til tilrettelegging for livslang læring og sosial utjevning. På den andre siden ser kartleggingsskeptikerne ut til å befinne seg innenfor den nordiske barnehagemodellen, som tradisjonelt bygger på et helhetlig syn på læring og på en sterk vektlegging av barndommens egenverdi. Spenningen kan ha store konsekvenser for praksisfeltet. I denne artikkelen drøfter jeg språkkartleggingsdiskursen i lys av teori om vitenskapelige kontroverser og konkluderer med at det er åpning for kompromisser, men også at det er tendenser i diskursen som snarere kan forsterke enn redusere uenigheten om språkkartlegging av flerspråklige barn i barnehagen. Mapping of language skills in early childhood education and care (ECEC institutions is controversial. On the one hand, there are those who support language mapping based on a belief that mapping and measuring can help language acquisition and facilitate lifelong learning and social integration. On the other hand, there are skeptics who oppose mapping and emphasize the values of childhood. This article discusses the discourses on language mapping in light of theories on scientific controversies. Based on the analysis I find that although there are openings for compromises, it seems that tendencies in the discourse may amplify rather than reduce the controversy on the language mapping of multilingual children in Norwegian ECEC institutions.

    This paper compares the coding efficiency performance on 360 videos, of three software codecs: (a) AV1 video codec from the Alliance for Open Media (AOM); (b) the HEVC Reference Software HM; and (c) the JVET JEM Reference SW. Note that 360 video is especially challenging content, in that one codes full res globally, but typically looks locally (in a viewport), which magnifies errors. These are tested in two different projection formats ERP and RSP, to check consistency. Performance is tabulated for 1-pass encoding on two fronts: (1) objective performance based on end-to-end (E2E) metrics such as SPSNR-NN, and WS-PSNR, currently developed in the JVET committee; and (2) informal subjective assessment of static viewports. Constant quality encoding is performed with all the three codecs for an unbiased comparison of the core coding tools. Our general conclusion is that under constant quality coding, AV1 underperforms HEVC, which underperforms JVET. We also test with rate control, where AV1 currently underperforms the open source X265 HEVC codec. Objective and visual evidence is provided.

    In this paper we compare the coding efficiency of AVS 2.0[1] for engines of the Context-based Binary Arithmetic Coding (CBAC)[2] in the AVS 2.0 and the Context-Adaptive Binary Arithmetic Coder (CABAC)[3] in the HEVC[4]. For fair comparison, the CABAC is embedded in the reference code RD10.1 because the CBAC is in the HEVC in our previous work[5]. The rate estimation table is employed only for RDOQ in the RD code. To reduce the computation complexity of the video encoder, therefore we modified the RD code so that the rate estimation table is employed for all RDO decision. Furthermore, we also simplify the complexity of rate estimation table by reducing the bit depth of its fractional part to 2 from 8. The simulation result shows that the CABAC has the BD-rate loss of about 0.7% compared to the CBAC. It seems that the CBAC is a little more efficient than that the CABAC in the AVS 2.0.

    Full Text Available Når det gjelder romanen Naustet av Jon Fosse er det ikke tvil om at det blant annet – og kanskje hovedsaklig – er „dette noko / skrifta berettar om“. Det er derfor denne romanen også kan kalles for en metaroman. Tematiseringen av skriveren og skriveprosessen i romanen tar ikke bare mye plass på historienivå: Den gjennomsyrer romanen. Nært forbundet med denne tematikken er et fenomen jeg ville kalle for „dobbeltperspektivet i romanen“, og det er dette jeg vil se litt nærmere på her. Selv om romanen Naustet – i god postmoderne tradisjon – i siste – og kanskje allerede i første – instans unndrar seg en fast og entydig tilskrivning av betydning – og slik bevarer sin magi – skal jeg prøve å nærme meg skriveren og dobbeltperspektivet „eit stykke på veg“. Men først et par ord om begrepet skriver.

    Introduction: 9-[ 18 F]Fluoropropyl-(+)-dihydrotetrabenazine ([ 18 F]AV-133) is a new PET imaging agent targeting vesicular monoamine transporter type II (VMAT2). To shorten the preparation of [ 18 F]AV-133 and to make it more widely available, a simple and rapid purification method using solid-phase extraction (SPE) instead of high-pressure liquid chromatography (HPLC) was developed. The SPE method produced doses containing the non-radioactive pseudo-carrier 9-hydroxypropyl-(+)-dihydrotetrabenazine (AV-149). The objectives of this study were to evaluate the brain uptake of AV-149 by UPLC-MS/MS and its effect on the biodistribution of [ 18 F]AV-133 in the brains of mice. Methods: The mice were injected with a bolus including [ 18 F]AV-133 and different doses of AV-149. Brain tissue and blood samples were harvested. The effect of different amounts of AV-149 on [ 18 F]AV-133 was evaluated by quantifying the brain distribution of radiolabelled tracer [ 18 F]AV-133. The concentrations of AV-149 in the brain and plasma were analyzed using a UPLC-MS/MS method. Results: The concentrations of AV-149 in the brain and plasma exhibited a good linear relationship with the doses. The receptor occupancy curve was fit, and the calculated ED 50 value was 8.165 mg/kg. The brain biodistribution and regional selectivity of [ 18 F]AV-133 had no obvious differences at AV-149 doses lower than 0.1 mg/kg. With increasing doses of AV-149, the brain biodistribution of [ 18 F]AV-133 changed significantly. Conclusion: The results are important to further support that the improved radiolabelling procedure of [ 18 F]AV-133 using an SPE method may be suitable for routine clinical application

  7. Phase 1 Trial of Subcutaneous rAvPAL-PEG in Subjects with Phenylketonuria

    Objective Phenylketonuria is an inherited disease caused by impaired activity of phenylalanine hydroxylase, the enzyme that converts phenylalanine to tyrosine, leading to accumulation of phenylalanine and subsequent neurocognitive dysfunction. A phenylalanine-restricted diet initiated early in life can ameliorate the toxic effects of phenylalanine. However, the diet is onerous and compliance is extremely difficult. Phenylalanine ammonia lyase (PAL) is a prokaryotic enzyme that converts phenylalanine to ammonia and trans-cinnamic acid. This Phase 1, multicenter clinical trial evaluated the safety, tolerability, pharmacokinetics and efficacy of rAvPAL-PEG (recombinant Anabaena variabilis PAL produced in E. coli conjugated with polyethylene glycol [PEG] to reduce immunogenicity) in reducing phenylalanine levels in subjects with phenylketonuria. Methods Single subcutaneous injections of rAvPAL-PEG in escalating doses (0·001, 0·003, 0·01, 0·03, and 0·1 mg/kg) were administered to 25 adults with phenylketonuria recruited from those attending metabolic clinics in North America whose blood phenylalanine concentrations were ≥600 μmol/L. Results The most frequently reported adverse events were injection-site reactions and dizziness. Reactions were self-limited without sequelae. During the trial, two subjects had adverse reactions to intramuscular (IM) medroxyprogesterone acetate, a drug containing polyethylene glycol as an excipient. Three subjects developed a generalized skin rash at the highest rAvPAL-PEG dose (0·1 mg/kg). Drug levels peaked ∼5 days after the injection. Treatment was effective in reducing blood phenylalanine in all five subjects receiving the highest dose (0·1 mg/kg, mean percent change of -58 from baseline), with a nadir ∼6 days after injection and inverse correlation between drug and phenylalanine concentrations in plasma. Phenylalanine concentrations returned to near-baseline levels ∼20 days after the single injection. Conclusions

  8. Atorvastatin and fenofibrate increase apolipoprotein AV and decrease triglycerides by up-regulating peroxisome proliferator-activated receptor-α

    Background and purpose: Combining statin and fibrate in clinical practice provides a greater reduction of triglycerides than either drug given alone, but the mechanism for this effect is poorly understood. Apolipoprotein AV (apoAV) has been implicated in triglyceride metabolism. This study was designed to investigate the effect of the combination of statin and fibrate on apoAV and the underlying mechanism(s). Experimental approach: Hypertriglyceridaemia was induced in rats by giving them 10% fructose in drinking water for 2 weeks. They were then treated with atorvastatin, fenofibrate or the two agents combined for 4 weeks, and plasma triglyceride and apoAV measured. We also tested the effects of these two agents on triglycerides and apoAV in HepG2 cells in culture. Western blot and reverse transcription polymerase chain reaction was used to measure apoAV and peroxisome proliferator-activated receptor-α (PPARα) expression. Key results: The combination of atorvastatin and fenofibrate resulted in a greater decrease in plasma triglycerides and a greater increase in plasma and hepatic apoAV than either agent given alone. Hepatic expression of the PPARα was also more extensively up-regulated in rats treated with the combination. A similar, greater increase in apoAV and a greater decrease in triglycerides were observed following treatment of HepG2 cells pre-exposed to fructose), with the combination. Adding an inhibitor of PPARα (MK886) abolished the effects of atorvastatin on HepG2 cells. Conclusions and implications: A combination of atorvastatin and fenofibrate increased apoAV and decreased triglycerides through up-regulation of PPARα. PMID:19694729

    Lilly/Avid's AV-1451 is one of the most advanced tau PET tracers in the clinic. Although results obtained in Alzheimer's disease patients are compelling, discrimination of tracer uptake in healthy individuals and patients with supranuclear palsy (PSP) is less clear as there is substantial overlap of signal in multiple brain regions. Moreover, accurate quantification of [ 18 F]AV-1451 uptake in Alzheimer's disease may not be possible. The aim of the present study was to characterize the in vitro binding of AV-1451 to understand and identify potential off-target binding that could explain the poor discrimination observed in PSP patients. [ 3 H]AV-1451 and AV-1451 were characterized in in vitro binding assays using recombinant and native proteins/tissues from postmortem samples of controls and Alzheimer's disease and PSP patients. [ 3 H]AV-1451 binds to multiple sites with nanomolar affinities in brain homogenates and to tau fibrils isolated from Alzheimer's disease or PSP patients. [ 3 H]AV-1451 also binds with similarly high affinities in brain homogenates devoid of tau pathology. This unexpected binding was demonstrated to be because of nanomolar affinities of [ 3 H]AV-1451 for monoamine oxidase A and B enzymes. High affinity of AV-1451 for monoamine oxidase proteins may limit its utility as a tau PET tracer in PSP and Alzheimer's disease because of high levels of monoamine oxidase expression in brain regions also affected by tau deposition, especially if monoamine oxidase levels change over time or with a treatment intervention. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

    Cerebral glucose metabolism measured with [18F]-FDG PET is a well established marker of neuronal dysfunction in neurodegeneration. The tau-protein tracer [18F]-AV-1451 PET is currently under evaluation and shows promising results. Here, we assess the feasibility of early perfusion imaging with AV-1451 as a substite for FDG PET in assessing neuronal injury. Twenty patients with suspected neurodegeneration underwent FDG and early phase AV-1451 PET imaging. Ten one-minute timeframes were acquired after application of 200 MBq AV-1451. FDG images were acquired on a different date according to clinical protocol. Early AV-1451 timeframes were coregistered to individual FDG-scans and spatially normalized. Voxel-wise intermodal correlations were calculated on within-subject level for every possible time window. The window with highest pooled correlation was considered optimal. Z-transformed deviation maps (ZMs) were created from both FDG and early AV-1451 images, comparing against FDG images of healthy controls. Regional patterns and extent of perfusion deficits were highly comparable to metabolic deficits. Best results were observed in a time window from 60 to 360 s (r = 0.86). Correlation strength ranged from r = 0.96 (subcortical gray matter) to 0.83 (frontal lobe) in regional analysis. ZMs of early AV-1451 and FDG images were highly similar. Perfusion imaging with AV-1451 is a valid biomarker for assessment of neuronal dysfunction in neurodegenerative diseases. Radiation exposure and complexity of the diagnostic workup could be reduced significantly by routine acquisition of early AV-1451 images, sparing additional FDG PET.

    Full Text Available I samband med den forskning och forsöksverksamhet som bedrivits vid renforsöksavdelningen har vi arbetat med metodik och teknik som kan tillämpas vid studier av radioaktivt cesium i renbetesväxter och i renar. På betessidan har vi bl.a. arbetat med kontaminering av tungmetaller från gruvindustrin och nitrat efter kvävegödsling. Omfattande studier har utförts av renens mineralstatus och mineralämnesomsättning. Erfarenheter och kunskaper från dessa områden har utnyttjats for planering och genomförande av de studier som nu pågår beträffande radioaktivt cesium i renbetesväxter och renar.

  1. The relation between Acid Volatile Sulfides (AVS) and metal accumulation in aquatic invertebrates: implications of feeding behavior and ecology.

    2010-05-01

    The present study evaluates the relationship between Acid Volatile Sulfides (AVS) and metal accumulation in invertebrates with different feeding behavior and ecological preferences. Natural sediments, pore water and surface water, together with benthic and epibenthic invertebrates were sampled at 28 Flemish lowland rivers. Different metals as well as metal binding sediment characteristics including AVS were measured and multiple regression was used to study their relationship with accumulated metals in the invertebrates taxa. Bioaccumulation in the benthic taxa was primarily influenced by total metal concentrations in the sediment. Regarding the epibenthic taxa metal accumulation was mostly explained by the more bioavailable metal fractions in both the sediment and the water. AVS concentrations were generally better correlated with metal accumulation in the epibenthic invertebrates, rather than with the benthic taxa. Our results indicated that the relation between AVS and metal accumulation in aquatic invertebrates is highly dependent on feeding behavior and ecology. Copyright 2010 Elsevier Ltd.

    2017-12-01

    Full Text Available [18F]-AV-1451 is a leading tracer used with positron emission tomography (PET to quantify tau pathology. However, [18F]-AV-1451 shows “off target” or non-specific binding, which we define as binding of the tracer in unexpected areas unlikely to harbor aggregated tau based on autopsy literature [1]. Along with caudate, putamen, pallidum and thalamus non-specific binding [2,3], we have found binding in the superior portion of the cerebellar gray matter, leading us to use inferior cerebellar gray as the reference region. We also addressed binding in the posterior portion of the choroid plexus. PET signal unlikely to be associated with tau also occurs in skull, meninges and soft tissue (see e.g. [4]. We refer to [18F]-AV-1451 binding in the skull and meninges as extra-cortical hotspots (ECH and find them near lateral and medial orbitofrontal, lateral occipital, inferior and middle temporal, superior and inferior parietal, and inferior cerebellar gray matter. Lastly, the choroid plexus also shows non-specific binding that bleeds into hippocampus. We are providing the code (http://www.runmycode.org/companion/view/2798 used to create different regions of interest (ROIs that we then used to perform Partial Volume Correction (PVC using the Rousset geometric transfer matrix method (GTM, [5].

    Full Text Available This article examines different stages in the life of A.V. Lunacharsky that allow defining his activity as triumphal, and at the same time, tragic. It demonstrates how his personal qualities, high level of education and encyclopedic knowledge become the basis for his successful activity in the field of Soviet culture. The article analyzes Lunacharsky’s relationship with bourgeois intellectuals, and focuses on contradictions in his world outlook. The article provides arguments in support of the opinion of impossibility to combine ideas of humanism that refuse violence in any form, with Bolshevik ideas that attempt to justify violence.

    Guler, Y; Akgun, T; Toprak, C; Guler, A; Esen, A M

    2014-05-01

    Cor triatriatum dexter (CTD) is an extremely rare cardiac anomaly in which the right atrium is divided into two distinct chambers by a membrane. The persistence of the right valve of sinus venosus results in a complete septation of the right atrium. This anomaly is frequently associated with other right-sided cardiac abnormalities. Its clinical manifestation and the need for intervention are determined by the number and the size of the fenestrations on the membrane, associated cardiac anomalies and arrhythmias. We describe a case of CTD in a patient with complete atrioventricular (A-V) block.

    2009-09-01

    Full Text Available Kunnskap om effekten av medisinsk behandling fremskaffes i kliniske studier. Godt planlagte og gjennomførte randomiserte, placebokontrollerte studier tillegges størst vekt når data skal vurderes. De datamengdene vi besitter når det gjelder forskjellige behandlinger kan oppsummeres i oversikter eller terapianbefalinger som ofte blir normative for klinisk praksis. Dette stiller store krav til evalueringsprosedyrene. I denne oversiktsartikkelen diskuteres i innledningen noen eksempler på at kunnskapsgrunnlaget er blitt feiltolket. Deretter omtales kvalitetskriterier som legges til grunn i vurderingen av data, og den metodologiske basis for meta-analyser. Usikkerhetsmomenter og potensielle fallgruver ved bruk av meta-analyser omtales. Meta-analysens fortrinn eksemplifiseres ved bruk av data om behandling av korsryggsmerter, hvor det nylig er utarbeidet kliniske retningslinjer som etter vår oppfatning er beheftet med feil eller mangler. Meta-analysen har vesentlige fortrinn fremfor mindre formaliserte metoder for oppsummering av kunnskap om terapi ved sykdom

  2. Development of an Advanced Aidman Vision Screener (AVS) for selective assessment of outer and inner laser induced retinal injury

    Boye, Michael W.; Zwick, Harry; Stuck, Bruce E.; Edsall, Peter R.; Akers, Andre

    2007-02-01

    The need for tools that can assist in evaluating visual function is an essential and a growing requirement as lasers on the modern battlefield mature and proliferate. The requirement for rapid and sensitive vision assessment under field conditions produced the USAMRD Aidman Vision Screener (AVS), designed to be used as a field diagnostic tool for assessing laser induced retinal damage. In this paper, we describe additions to the AVS designed to provide a more sensitive assessment of laser induced retinal dysfunction. The AVS incorporates spectral LogMar Acuity targets without and with neural opponent chromatic backgrounds. Thus, it provides the capability of detecting selective photoreceptor damage and its functional consequences at the level of both the outer and inner retina. Modifications to the original achromatic AVS have been implemented to detect selective cone system dysfunction by providing LogMar acuity Landolt rings associated with the peak spectral absorption regions of the S (short), M (middle), and L (long) wavelength cone photoreceptor systems. Evaluation of inner retinal dysfunction associated with selective outer cone damage employs LogMar spectral acuity charts with backgrounds that are neurally opponent. Thus, the AVS provides the capability to assess the effect of selective cone dysfunction on the normal neural balance at the level of the inner retinal interactions. Test and opponent background spectra have been optimized by using color space metrics. A minimal number of three AVS evaluations will be utilized to provide an estimate of false alarm level.

  3. Seasonal AVS-SEM relationship in sediments and potential bioavailability of metals in industrialized estuary, southeastern Brazil.

    Science.gov (United States)

    Nizoli, Erico Casare; Luiz-Silva, Wanilson

    2012-04-01

    In anoxic sediments, as those found in estuaries, the mobility of metals can be controlled by the formation of stable sulfide complexes. The potential bioavailability of a metal can then be predicted on the basis of the acid volatile sulfide (AVS) and simultaneously extracted metals (SEM) criterion. Distributions of AVS and SEM (Hg, Cu, Pb, Cd, Zn, and Ni) along the sediment profiles were determined seasonally for three rivers that constitute the Santos-Cubatão estuarine system (SE Brazil), which is located in one of the most industrialized areas of Latin America. AVS and SEM concentrations varied significantly, from 0.04 to 31.9 μmol g(-1) and 0.086-6.659 μmol g(-1), respectively. The highest AVS levels in sediments were detected in the winter, whereas high SEM values predominated in the summer. Considering SEM-AVS molar differences as a parameter to evaluate potential bioavailability, sediments nearest to the industrial area represent higher risk to biota, especially during the summer. It is due to relatively low AVS values and not necessarily high concentrations of metals.

    Google started the WebM Project in 2010 to develop open source, royalty- free video codecs designed specifically for media on the Web. The second generation codec released by the WebM project, VP9, is currently served by YouTube, and enjoys billions of views per day. Realizing the need for even greater compression efficiency to cope with the growing demand for video on the web, the WebM team embarked on an ambitious project to develop a next edition codec AV1, in a consortium of major tech companies called the Alliance for Open Media, that achieves at least a generational improvement in coding efficiency over VP9. In this paper, we focus primarily on new tools in AV1 that improve the prediction of pixel blocks before transforms, quantization and entropy coding are invoked. Specifically, we describe tools and coding modes that improve intra, inter and combined inter-intra prediction. Results are presented on standard test sets.

    Advanced Vitrification System (AVS) is commissioned for vitrification of high level waste (HLW) by using Joule heated ceramic melter first time in India. The HLW is generated in fuel reprocessing plant. For radiological surveillance of plant, Health Physics Unit (HPU) had installed 37 Area Gamma Monitors (AGM), 7 Continuous Air Monitors (CAM) and all types of personal contamination monitors. Exposure control is a major concern in operating plant. Therefore in addition to installed monitors, we have developed online remote radiation monitoring system to minimize exposures to the surveyor and operator. This also helped in volume reduction of secondary waste. The reliability and accuracy of the online monitoring system is confirmed by calibrating the system by comparing TLD and DRD readings and by theoretical analysis. In addition some modifications were carried in HP instruments to make them user friendly. This paper summarizes different kinds of remote radiological monitoring systems installed for online monitoring of Melter off Gas (MOG) filter, Hood filter, three exhaust filter banks, annulus air sampling and over pack monitoring in AVS. Our online remote monitoring system has helped the plant management to plan in advance for replacement of these filters, which resulted in considerable saving of collective dose. (author)

En høy fruktbarhet i reinflokken er selve grunnlaget for en vellykket reindrift. Overraskende er det derfor at man vet lite om hvilke faktorer som bestemmer om rein skal bli drektig eller ikke. I denne artikkelen blir effekten av ernæring på reinsimlenes fruktbarhet diskutert. Undersøkelser indikerer at rein er som andre pattedyr, der fruktbarheten er relatert til kroppsvekten. Forholdet mellom reinens kroppsvekt og fruktbarhet varierer likevel sterkt. Mye tyder på at drektighetsprosenten i ungrein er avhengig av reintettheten. Dette indikerer at ernæringen er en viktig faktor når det gjelder fruktbarhet i ungrein. Vektspesifikk fruktbarhet kan derfor være en brukbar indikator for reinflokkens fortilgang. I prinsippet vil slike fruktbarhetsundersøkelser gi et tidlig varsel om reintallet er for høyt i forhold til beitegrunnlaget før en markert nedgang i slaktevekten observeres. Etter foredraget til Nic.

    The background model for AVS-F apparatus onboard CORONAS-F satellite for the October 29, 2003 X10-class solar flare is discussed in the presented work. This background model developed for AVS-F counts rate in the low- and high-energy spectral ranges in both individual channels and summarized. Count rate were approximated by polynomials of high order taking into account the mean count rate in the geomagnetic equatorial region at the different orbits parts and Kp-index averaged on 5 bins in time interval from -24 to -12 hours before the time of geomagnetic equator passing. The observed averaged counts rate on equator in the region of geomagnetic latitude ±5o and estimated minimum count rate values are in coincidence within statistical errors for all selected orbits parts used for background modeling. This model will used to refine the estimated energy of registered during the solar flare spectral features and detailed analysis of their temporal profiles behavior both in corresponding energy bands and in summarized energy range.

    Like most gram-positive oral bacteria, Actinomyces naeslundii is resistant to salivary lysozyme and to most other lytic enzymes. We are interested in studying the lysins of phages of this important oral bacterium as potential diagnostic and therapeutic agents. To identify the Actinomyces phage genes encoding these species-specific enzymes in Escherichia coli, we constructed a new cloning vector, pAD330, that can be used to enrich for and isolate phage holin genes, which are located adjacent to the lysin genes in most phage genomes. Cloned holin insert sequences were used to design sequencing primers to identify nearby lysin genes by using whole phage DNA as the template. From partial digestions of A. naeslundii phage Av-1 genomic DNA we were able to clone, in independent experiments, inserts that complemented the defective λ holin in pAD330, as evidenced by extensive lysis after thermal induction. The DNA sequence of the inserts in these plasmids revealed that both contained the complete lysis region of Av-1, which is comprised of two holin-like genes, designated holA and holB, and an endolysin gene, designated lysA. We were able to subclone and express these genes and determine some of the functional properties of their gene products. PMID:16461656

    Little is known about Alzheimer's disease molecular proteins, beta-amyloid and paired helical filament (PHF) tau, in progressive supranuclear palsy (PSP). Recent techniques have been developed to allow for investigations of these proteins in PSP. We determined the frequency of beta-amyloid deposition in PSP, and whether beta-amyloid deposition in PSP is associated with PHF-tau deposition pattern, or clinical features. Thirty probable PSP participants underwent MRI, [ 18 F]AV-1451 PET and Pittsburgh compound B (PiB) PET. Apolipoprotein (APOE) genotyping was also performed. A global PiB standard-uptake value ratio (SUVR) was calculated. AV-1451 SUVRs were calculated for a set of Alzheimer's disease (AD)-related regions and a set of PSP-related regions. Voxel-level analyses were conducted to assess for differences in AV-1451 uptake patterns and MRI atrophy between PiB(+) and PiB(-) cases compared to 60 normal PiB(-) controls. Statistical testing for correlations and associations between variables of interest were also performed. Twelve subjects (40%) showed beta-amyloid deposition. Higher PiB SUVR correlated with older age but not with AV-1451 SUVR in the AD- or PSP-related regions. Higher AV-1451 SUVR in AD-related regions was associated with higher AV-1451 SUVR in PSP-related regions. We found little evidence for beta-amyloid related differences in clinical metrics, proportion of APOE e4 carriers, pattern of AV-1451 uptake, or pattern of atrophy. Beta-amyloid deposition occurs in a relatively high proportion of PSP subjects. Unlike in Alzheimer's disease, however, there is little evidence that beta-amyloid, and PHF-tau, play a significant role in neurodegeneration in PSP. Copyright © 2017 Elsevier Ltd.

    Comparison of echocardiographic findings in AVS patients with and without high IgG, IgM, IgA titers against Chlamydia pneumoniae during 12 months' observation of AVS natural course. 60 AVS patients who did not agree for operational treatment were divided into group A (30 patients with high IgG titer) group B (30 patients with low IgG titer), group C (22 patients with high IgA titer) group D (38 patients with low IgA titer), group E (7 patients with high IgM titer), group F (53 patients with low IgA titer) Antibodies titers and echocardiographic scans were carried out every 12 months. There were more (p AVS deterioration in group A compared to group B. Group A patients had lower left ventricle posteriori wall systolic diameter compared to group B. There were no differences in echocardiographic parameters between group C and D. Mean ejection fraction was lower and mean right atrium diameter was higher in group E compared to group F. The results may suggest link between Chlamydia pneumoniae and deterioration of AVS.

    Asteroid 4 Vesta is currently under investigation by NASA's Dawn orbiter. The Dawn Science Team is conducting mineralogical mapping of Vesta's surface in the form of 15 quadrangle maps, and here we report results from the mapping of Floronia quadrangle Av-5. The maps are based on the data acquired by the Visible and Infrared Mapping Spectrometer (VIR-MS) and the Framing Camera (FC) (De Sanctis et al., this meeting). This abstract is focused on the analysis of band ratios, as well as the depth and position of the 2-µm absorption band of pyroxenes, but additional information will be presented. Absorption band depth is sensitive to abundance, texture and multiple scattering effects. Absorption band position is controlled by composition, shorter wavelength positions indicate less Calcium (and more Magnesium) in pyroxenes. The inferred composition is compared with that of Howardite, Eucite and Diogenite meteorites (HEDs). Diogenites are Mg-rich with large orthopyroxene crystals suggesting formation in depth; Eucrites are Ca-poor pyroxene, with smaller crystals. Av-5 Floronia Quadrangle is located between ~20-66˚N and 270˚-360˚E. It covers a portion of the heavily-cratered northern hemisphere of Vesta, and part of it is in permanent night, until August 2012. Long shadows make the visualization of albedo variations difficult, because of limited effectiveness of photometric corrections. Most of the variations of the band depth at 2 µm are partly affected by illumination geometry in this area. Only regional tendencies are meaningful at this time of the analysis. The 2-µm absorption band depth seems to be deeper towards the south of the quadrangle, in particular to the south of Floronia crater. It is not possible to interpret the value of the band depth in the floor the craters because of the absence of direct sunlight. However, the illuminated rims seem to have a deeper 2-µm absorption band, as does the ejecta from an unnamed crater located further south, within

    The present study evaluates the relationship between Acid Volatile Sulfides (AVS) and metal accumulation in invertebrates with different feeding behavior and ecological preferences. Natural sediments, pore water and surface water, together with benthic and epibenthic invertebrates were sampled at 28 Flemish lowland rivers. Different metals as well as metal binding sediment characteristics including AVS were measured and multiple regression was used to study their relationship with accumulated metals in the invertebrates taxa. Bioaccumulation in the benthic taxa was primarily influenced by total metal concentrations in the sediment. Regarding the epibenthic taxa metal accumulation was mostly explained by the more bioavailable metal fractions in both the sediment and the water. AVS concentrations were generally better correlated with metal accumulation in the epibenthic invertebrates, rather than with the benthic taxa. Our results indicated that the relation between AVS and metal accumulation in aquatic invertebrates is highly dependent on feeding behavior and ecology. - The relation between AVS and metal accumulation in aquatic invertebrates is highly dependent on feeding behavior and ecology.

    The excitatory amino acid L-glutamate injected into the nucleus of the solitary tract (NTS) in unanesthetized rats similar to peripheral chemoreceptor activation increases mean arterial pressure (MAP) and reduces heart rate. In this study, we investigated the effects of acute (1 day) and chronic (15 days) electrolytic lesions of the preoptic-periventricular tissue surrounding the anteroventral third ventricle (AV3V region) on the pressor and bradycardic responses induced by injections of L-glutamate into the NTS or peripheral chemoreceptor activation in unanesthetized rats. Male Holtzman rats with sham or electrolytic AV3V lesions and a stainless steel cannula implanted into the NTS were used. Differently from the pressor responses (28+/-3 mm Hg) produced by injections into the NTS of sham-lesioned rats, L-glutamate (5 nmol/100 nl) injected into the NTS reduced MAP (-26+/-8 mm Hg) or produced no effect (2+/-7 mm Hg) in acute and chronic AV3V-lesioned rats, respectively. The bradycardia to l-glutamate into the NTS and the cardiovascular responses to chemoreflex activation with intravenous potassium cyanide or to baroreflex activation with intravenous phenylephrine or sodium nitroprusside were not modified by AV3V lesions. The results show that the integrity of the AV3V region is essential for the pressor responses to L-glutamate into the NTS but not for the pressor responses to chemoreflex activation, suggesting dissociation between the central mechanisms involved in these responses.

I denne artikkelen fokuserer vi på kommersiell gestational surrogati og stiller spørsmålet: Bør man tillate at norske statsborgere benytter seg av surrogati i India? De etiske problemstillingene rundt surrogati er mange og sammensatte og blir spesielt utfordrende når tjenesten tilbys i et land med store kulturelle og økonomiske forskjeller både internt og i forhold til Norge. Vi baserer analysen og drøftingen av dette etisk utfordrende spørsmålet på Beauchamps og Childress sin veletablerte metodiske tilnærming innen biomedisinsk etikk.

    HPCMP CREATE-AV Conservative Field Finite Element (COFFE) is a modular, extensible, robust numerical solver for the Navier-Stokes equations that invokes modularity and extensibility from its first principles. COFFE implores a flexible, class-based hierarchy that provides a modular approach consisting of discretization, physics, parallelization, and linear algebra components. These components are developed with modern software engineering principles to ensure ease of uptake from a user's or developer's perspective. The Streamwise Upwind/Petrov-Galerkin (SU/PG) method is utilized to discretize the compressible Reynolds-Averaged Navier-Stokes (RANS) equations tightly coupled with a variety of turbulence models. The mathematics and the philosophy of the methodology that makes up COFFE are presented.

    Recent experiments on vanadium oxide bronzes AV 2 O 5 (A=Na, Mg, Li) are reviewed. Experiments are carried out combining two triple-axis spectrometers installed at a thermal beam port and a cold neutron guide at JRR-3M. Spin-wave excitations in single crystals NaV 2 O 5 in the spin-Peierls state shows a steep intra-chain dispersion, which is consistent with estimated exchange interaction from magnetization measurement, and a weak inter-chain dispersion. In the low energy excitation measurement on powder sample of MgV 2 O 5 , we have observed energy gap of 2 meV, which indicates that this material is a ladder system with strong 1D character. Preliminary result on LiV 2 O 5 , which is expected to be a simple 1D antiferromagnet or a zig-zag chain, is also mentioned

    Full Text Available Unilateral diaphragmatic palsy reduces pulmonary function by about 25% in older children and usually it is well tolerated; however, it causes severe respiratory distress in infants and young children. Diaphragmatic plication performed later than 10 days after cardiac surgery for patients under 1 year of age was associated with higher incidence of pneumonia and mortality. The management of the diaphragmatic paralysis due to phrenic nerve injury aiming mainly to preserve the respiratory function. Until now, the optimal management of diaphragmatic palsy in children who have undergone cardiac surgery remains controversial and consists of prolonged ventilation or diaphragmatic plication. In our case, many factors supported early diaphragmatic plication, the age of the patient, post-operative AV canal repair with severe pulmonary hypertension, and clear transection of the left phrenic nerve diagnosed intraoperatively.

  9. Dependence of Coulomb Sum Rule on the Short Range Correlation by Using Av18 Potential

    Science.gov (United States)

    Modarres, M.; Moeini, H.; Moshfegh, H. R.

    The Coulomb sum rule (CSR) and structure factor are calculated for inelastic electron scattering from nuclear matter at zero and finite temperature in the nonrelativistic limit. The effect of short-range correlation (SRC) is presented by using lowest order constrained variational (LOCV) method and the Argonne Av18 and Δ-Reid soft-core potentials. The effects of different potentials as well as temperature are investigated. It is found that the nonrelativistic version of Bjorken scaling approximately sets in at the momentum transfer of about 1.1 to 1.2 GeV/c and the increase of temperature makes it to decrease. While different potentials do not significantly change CSR, the SRC improves the Coulomb sum rule and we get reasonably close results to both experimental data and others theoretical predictions.

Chayanov (1888-1937 is a famous Russian economist, theorist of the organization of economy, a brilliant representative of the generation of the “golden age” of the economic science in Russia. One of the key elements of his scientific legacy is the theory of non-capitalist forms of economy, and one of its aspects - international agrarian studies of the features of the organization of agriculture in different countries. The organizational-production school developed a theory of labor economy and came close to the general theory of non-capitalist forms of economy; however, its studies were inter-rupted by the repressions of the 1920s.

The author proposes a new interpretation of the organizational-production school as having a dualistic character. The works of Alexander N. Chelintsev (1874-1962, Nicholay P. Makarov (1886-1980 and other colleagues of A.V. Chayanov from the organizational-production school focused on both theoretical issues such as the fundamental laws of functioning and development of agriculture, and practical issues of scientific management of an individual farm and agriculture in general. The author considers the orga-nizational-production school as dualistic: it studies both theory and management of peasant economy at micro- and macro-levels proceeding from the analysis of the individual farm structure to the issues of the optimal production location and optimal management of ‘a mass of peasant farms’. The system approach to the organization of economy, cooperation, zoning and economic policy developed by the organizational-production school is still relevant for the contemporary use.

    The interaction between surfaces and biological elements, in particular, proteins is critical for the performance of biomaterials and biosensors. This interaction can be controlled by modifying the surface in a process known as biofunctionalization. In this work, the enzyme lactate dehydrogenase (LDH) is used to study the stability of the interaction between a functional protein and amine-functionalized surfaces. Two different functionalization procedures were compared: Activated Vapor Silanization (AVS) and Immersion Silanization (IS). Adsorption kinetics is shown to follow the Langmuir model for AVS-functionalized samples, while IS-functionalized samples show a certain instability if immersed in an aqueous medium for several hours. In turn, the enzymatic activity of LDH is preserved for longer times by using glutaraldehyde as crosslinker between the AVS biofunctional surface and the enzyme.

    Szoboszlay, Zoltan; Haworth, Loran; Simpson, Carol

    2000-01-01

    A flight test was conducted to assess any differences in pilot-vehicle performance and pilot opinion between the use of a current generation night vision goggle (the AVS-9) and one variant of the prototype panoramic night vision goggle (the PNVGII). The panoramic goggle has more than double the horizontal field-of-view of the AVS-9, but reduced image quality. Overall the panoramic goggles compared well to the AVS-9 goggles. However, pilot comment and data are consistent with the assertion that some of the benefits of additional field-of-view with the panoramic goggles were negated by the reduced image quality of the particular variant of the panoramic goggles tested.

    A bacterial consortium-AVS, consisting of Pseudomonas desmolyticum NCIM 2112, Kocuria rosea MTCC 1532 and Micrococcus glutamicus NCIM 2168 was formulated chemometrically, using the mixture design matrix based on the design of experiments methodology. The formulated consortium-AVS decolorized acid blue 15 and methylene blue with a higher average decolorization rate, which is more rapid than that of the pure cultures. The UV-vis spectrophotometric, Fourier transform infra red spectrophotometric and high performance liquid chromatographic analysis confirm that the decolorization was due to biodegradation by oxido-reductive enzymes, produced by the consortium-AVS. The toxicological assessment of plant growth parameters and the chlorophyll pigment concentrations of Phaseolus mungo and Triticum aestivum seedlings revealed the reduced toxic nature of the biodegraded products.

  7. Left Ventricular Dysfunction Caused by Unrecognized Surgical AV block in a Patient with a Manifest Right Free Wall Accessory Pathway

    Directory of Open Access Journals (Sweden)

    Rakesh Gopinathannair, MD, MA

    2013-05-01

    Full Text Available A 24-year-old male with Wolff-Parkinson-White syndrome developed systolic cardiomyopathy and severe heart failure following membranous ventricular septal defect repair and tricuspid valve replacement. Following successful catheter ablation of a right anterolateral accessory pathway (AP, complete AV block with junctional escape rhythm was noted. Patient subsequently underwent implantation of a biventricular ICD. Heart failure symptoms significantly improved soon after and left ventricular systolic function normalized 3 months post-procedure. In this case, surgically acquired AV block likely explains development of postoperative cardiomyopathy by facilitating ventricular activation solely via the AP and thereby increasing the degree of ventricular dyssynchrony.

    To assess the relationships between fluid and imaging biomarkers of tau pathology and compare their diagnostic utility in a clinically heterogeneous sample. Fifty-three patients (28 with clinical Alzheimer disease [AD] and 25 with non-AD clinical neurodegenerative diagnoses) underwent β-amyloid (Aβ) and tau ([ 18 F]AV1451) PET and lumbar puncture. CSF biomarkers (Aβ 42 , total tau [t-tau], and phosphorylated tau [p-tau]) were measured by multianalyte immunoassay (AlzBio3). Receiver operator characteristic analyses were performed to compare discrimination of Aβ-positive AD from non-AD conditions across biomarkers. Correlations between CSF biomarkers and PET standardized uptake value ratios (SUVR) were assessed using skipped Pearson correlation coefficients. Voxelwise analyses were run to assess regional CSF-PET associations. [ 18 F]AV1451-PET cortical SUVR and p-tau showed excellent discrimination between Aβ-positive AD and non-AD conditions (area under the curve 0.92-0.94; ≤0.83 for other CSF measures), and reached 83% classification agreement. In the full sample, cortical [ 18 F]AV1451 was associated with all CSF biomarkers, most strongly with p-tau ( r = 0.75 vs 0.57 for t-tau and -0.49 for Aβ 42 ). When restricted to Aβ-positive patients with AD, [ 18 F]AV1451 SUVR correlated modestly with p-tau and t-tau (both r = 0.46) but not Aβ 42 ( r = 0.02). On voxelwise analysis, [ 18 F]AV1451 correlated with CSF p-tau in temporoparietal cortices and with t-tau in medial prefrontal regions. Within AD, Mini-Mental State Examination scores were associated with [ 18 F]AV1451-PET, but not CSF biomarkers. [ 18 F]AV1451-PET and CSF p-tau had comparable value for differential diagnosis. Correlations were robust in a heterogeneous clinical group but attenuated (although significant) in AD, suggesting that fluid and imaging biomarkers capture different aspects of tau pathology. This study provides Class III evidence that, in a clinical sample of patients with a variety

    The purpose of this study was to assemble and disseminate knowledge about bio-oils and other bio fuels which are used for heat- and power generation or liquid bio fuels/oils that may become interesting in the future. One aim of this study was to give an updated picture of the Swedish market for bio-oils and to provide an overview of practical experience on the usage of bio-oils in the Swedish heat and power industry. In order to show a green profile, bio-oils can be used in the heat and power generation. However, not all bio-oils can be viewed as climate friendly. Some production of bio-oils may actually - if a lifecycle perspective is considered - lead to increased emissions of greenhouse gases, and there are also ethical issues that need to be considered. The data collection was carried out in three different fields. The objective of the first part was to create an overview of the Swedish market for liquid bio fuels/oils for heat and power production. The second part of the study aimed to clarify the issues surrounding environmental and ethical issues associated with the use of different bio-oils. A selection of oil crops for a closer study was made based on production volume (soybean, palm oil and rapeseed) and expected future potential (jatropha). This part of the study was based on a literature review. In the third part of the study technical and practical experiences from using bio-oils in heat and power production were studied. The interviews made with purchasing managers in the second part gave valuable information on which utilities would be the most interesting to interview for the study of technical and practical experiences, where interviews were carried out with persons familiar with the daily operation of the plant. The use of liquid bio fuels was about 4.3 % of total fuel use in Swedish district heating production in 2007 (1.2 % pine oil and 3.0 % other bio-oil). In other words, it is mainly bio-oils that have been used and not other types of liquid bio fuels. The types of liquid bio fuels that have been studied are different qualities of bio-oils and glycerol that is a residual from biodiesel production. Vegetable bio-oils are the most commonly used in Swedish heat and power production amongst the liquid bio fuels. Vegetable oils can be extracted from a variety of different crops that grows all over the world. Due to today's fuel prices, the bio-oil that is used for heat and power production is mainly residue or by-products from industrial production of food, feed manufacturing, pharmaceuticals and cosmetics. The most abundant bio-oils that have been encountered during the interview process have come from oil palm or rapeseed or a mix of different residues from which the biological origin is difficult to trace. Tall oil pitch, which is a by-product in the pulp industry, has held a non-negligible share in Swedish heat production. Experiments on combustion of glycerol have recently been carried out and these indicate that glycerol does have a potential. According to the district heating companies that were interviewed, they did not experience that lack of availability of bio-oils was a problem, although the quality of the bio-oils could vary greatly. Most district heating companies have developed specifications for the fuel to be purchased. All parties benefit from a good specification where the purchasing managers and the operational staff have consistent requirements. The liquid bio fuels used in Swedish heat production are, except for possibly the PFAD, not accepted products, but different types of residues or by-products. There is no commodity exchange where the products are traded and there are a variety of factors affecting the price formation, making the pricing very complex. The study discusses various aspects of the use of bio-oils with a focus on a few crops of particular interest. These are soybean, oil palm, rapeseed and jatropha. The first three are interesting because of their large production volume, but also because of the infective debates that have been going on about the environmental and social impacts of the increased demand for bio-oils. It is common knowledge that some initial problems occur when converting a plant from fossil oil to bio-oil. One of the interviewees summoned the situation with the words: 'It's been a process to learn where the problems are'. The different types of experiences that have been illuminated in the interviews are: - Key characteristics in the choice of fuel is considered to be ash content, the amount of alkali, the amount of glycerol, water content, viscosity, amount of particles and fuel price. - The quality of the bio-oils differ to a great extent, much more than the quality of fossil oil does. This makes it important to have well developed specifications for the procurement of bio-oil and a good strategy for the control of fuel quality.

    During the 2010 and 2011 Icelandic volcanic eruptions, the availability of integrated, validated data sets was identified as a major challenge in the effort to gain a rapid situation assessment. These environmental crisis situations may happen again, also from other types ofairborne hazards, like big fires. Currently, the issue is not so much that data and observations do not exist, it is rather the rapid accessibility, the cross-calibration of different sensors, the integration of new platforms and the harmonization of standards and protocols that needs further work and attention. A specific activity is planned within the H-2020 project EUNADICS -AV ("European Natural Disaster Coordination and Information System for Aviation") for addressing this critical issue. In order to achieve the rapid data accessibility, work will be carried out with full consideration of the main European Research Infrastructures, projects and national/international monitoring networks that are able to provide crucial information related to the dispersion of airborne hazards. The integrated data sets are based on satellite and ground-based remote sensing as well as in situ ground-based and aircraft observations. Networks of ground based remote sensing of atmospheric profiles are particularly important, since these will provide the needed height information that cannot be obtained unambiguously from the vast majority of space borne sensors. A new aspect not treated in any project and initiative so far is the integration of special crisis measurements, for example by aircraft or UAV systems. Particularly suited for the purposes of the project are satellite data from operational sensors aboard EUMETSAT and ESA satellites. Improved retrievals are investigated, and the new generation of Sentinel satellites currently being launched under the Copernicus umbrella and their added value are considered. Especially when the ground based and space borne observations are combined, the much needed

    Scientific audiovisual media such as videos of research, interactive displays or computer animations has become an important part of scientific communication and education. Dynamic phenomena can be described better by audiovisual media than by words and pictures. For this reason, scientific videos help us to understand and discuss environmental phenomena more efficiently. Moreover, the creation of scientific videos is easier than ever, thanks to mobile devices and open source editing software. Video-clips, webinars or even the interactive part of a PICO are formats of scientific audiovisual media used in the Geosciences. This type of media translates the location-referenced Science Communication such as environmental interpretation into computed-based Science Communication. A new way of Science Communication is video abstracting. A video abstract is a three- to five-minute video statement that provides background information about a research paper. It also gives authors the opportunity to present their research activities to a wider audience. Since this kind of media have become an important part of scientific communication there is a need for reliable infrastructures which are capable of managing the digital assets researchers generate. Using the reference of the usecase of video abstracts this paper gives an overview over the activities by the German National Library of Science and Technology (TIB) regarding publishing and linking audiovisual media in a scientifically sound way. The German National Library of Science and Technology (TIB) in cooperation with the Hasso Plattner Institute (HPI) developed a web-based portal (av.tib.eu) that optimises access to scientific videos in the fields of science and technology. Videos from the realms of science and technology can easily be uploaded onto the TIB|AV Portal. Within a short period of time the videos are assigned a digital object identifier (DOI). This enables them to be referenced, cited, and linked (e.g. to the

    Aeromonas molluscorum Av27 is an estuarine bacterium highly resistant to tributyltin (TBT). Also, the strain is able to degrade TBT into the less toxic compounds dibutyltin and monobutyltin. Therefore, this bacterium has potential to be employed in bioremediation processes. In this context, defining its biological safety is crucial. With that purpose a number of intrinsic characteristics, usually present/associated with virulent strains, were investigated. Few virulence factors were detected in strain Av27. For instance, a DNase gene is present, but it is not apparently expressed in vitro. Motility, adherence factor and phospholipase activity were also detected. Additionally, cytotoxicity to Vero cells was negative. Resistance to penicillin (10 μg ml(-1)), amoxicillin/clavulanic acid (30 μg ml(-1)) and cephalothin (30 μg ml(-1)) and also to the vibriostatic agent O/129 was observed. Five plasmids (4, 7, 10, 100 kb and one greater than 100 kb) were identified. No Class I and II integrons were detected. Study of the optimal growth conditions showed that Av27 easily adapts to different environmental conditions. Overall, the results suggest that A. molluscorum Av27 can be considered safe to use to bioremediate TBT in contaminated environments.

    The present study evaluates the influence of acid volatile sulfides (AVS) on accumulation of sediment-bound metals in benthic invertebrates under natural field conditions. Natural sediments, pore water, surface water, and two species of widespread benthic invertebrates (Chironomus gr. thummi and Tubifex tubifex) were collected from 17 historical polluted Flemish lowland rivers and measured for metal concentrations. Different sediment characteristics were determined (AVS, organic matter, clay content) and multiple regression was used to study their relationship with accumulated metals in the invertebrates. Physical and chemical analysis of the field samples indicated low metal concentrations in the water and pore water, but very high metal concentrations in the sediment and the invertebrates, especially for Pb (5.99 micromol/ g). In general, metal accumulation in chironomids and tubificid worms was most strongly correlated with total metal concentrations in the sediment and sediment metal concentrations normalized for organic matter and clay content. Following the results of the linear regression model, AVS did not turn out to be a significant variable in describing variation in metal accumulation. Our study clearly demonstrates that, in addition to the results gained from experiments under lab conditions, benthic invertebrates can accumulate metals from unspiked field sediments even when there's an excess of AVS.

    Tributyltin (TBT) is a biocide extremely toxic to a wide range of organisms, which has been used for decades in antifouling paints. Despite its global ban in 2008, TBT is still a problem of great concern due to the high levels trapped in sediments. Aeromonas molluscorum Av27 is a TBT degrading bacterium that was isolated from an estuarine system. We investigated the ability and the role of this bacterium on TBT degradation in this estuarine system, using a microcosm approach in order to mimic environmental conditions. The experiment was established and followed for 150 days. Simultaneously, changes in the indigenous bacterial community structure were also investigated. The results revealed a maximum TBT degradation rate of 28% accompanied by the detection of the degradation products over time. Additionally, it was observed that TBT degradation was significantly enhanced by the presence of Av27. In addition a significantly higher TBT degradation occurred when the concentration of Av27 was higher. TBT degradation affected the bacterial community composition as revealed by the changes in the prevalence of Proteobacteria subdivisions, namely the increase of Deltaproteobacteria and the onset of Epsilonproteobacteria. However, the addition of Av27 strain did not affect the dominant phylotypes. Total bacterial number, bacterial biomass productivity, 16S rRNA gene and denaturing gradient gel electrophoresis (DGGE) analyses also indicated alterations on the bacterial community structure over time, with bacteria non-tolerant to pollutants increasing their representativeness, as, for instance, the increase of the number of Alphaproteobacteria clones from 6% in the beginning to 12% at the end of the experiment. The work herein presented confirms the potential of Av27 strain to be used in the decontamination of TBT-polluted environments. Copyright © 2014 Elsevier Inc. All rights reserved.

    Ruiz-Alonso, D; Coombs, T; Campbell, A M

    2004-01-01

    Numerical methods for calculating the current and field distribution in high-temperature superconductors under non-uniform time-varying fields are being investigated. The highly non-linear behaviour of superconductors makes them difficult to analyse and computationally expensive. This non-linear behaviour is often accounted for through a non-linear E-J constitutive law. This paper proposes a fast method based on the finite element method to solve 2D and axially symmetric problems that contain superconducting materials. An E-J power law together with an A-V formulation is used to calculate the induction of currents in the superconductor due to time-varying external magnetic fields or forced transport current. Experimental data of a magnet-above-superconductor system is obtained in order to validate the model. In the experimental set-up a magnet is brought towards a superconducting puck at different speed rates and is also vibrated on top of it. The force between the magnet and the superconductor is measured and is found to vary with both time and frequency of excitation

  13. Influence of apolipoprotein A-V on the metabolic fate of triacylglycerol.

    2013-04-01

    Apolipoprotein (apo) A-V functions to modulate intracellular and extracellular triacylglycerol metabolism. The present review addresses molecular mechanisms underlying these effects. The relevance of apoA-V to human disease conditions is illustrated by the strong correlation between single nucleotide polymorphisms in APOA5, elevated plasma triacylglycerol and dyslipidemic disease. Despite undergoing processing for secretion from hepatocytes, a portion of apoA-V escapes this destiny and accumulates as a component of cytosolic lipid droplets. Expression of recombinant apoA-V in hepatocarcinoma cells results in increased lipid droplet size and number at the expense of triacylglycerol secretion.ApoA-V modulates atherosclerosis in hypercholesterolemic apoE null mice. ApoE null/human apoA-V transgenic mice had reduced levels of triacylglycerol and cholesterol in plasma along with decreased aortic lesion size. ApoA-V modulates triacylglycerol metabolic fate. Following its synthesis, apoA-V enters the endoplasmic reticulum and associates with membrane defects created by triacylglycerol accumulation. Association of apoA-V with endoplasmic reticulum membrane defects promotes nascent lipid droplets budding toward the cytosol. Despite its low concentration in plasma (∼150 ng/ml), apoA-V modulates lipoprotein metabolism by binding to glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein 1. This interaction effectively localizes triacylglycerol-rich lipoproteins in the vicinity of glycosylphosphatidylinositol-anchored high-density lipoprotein binding protein1's other ligand, lipoprotein lipase.

    Full Text Available Å forske med kunsten innebærer ikke bare valget av visse metoder for bruk i forskningsprosessen, men også om å ha til disposisjon spesifikke måter å tenke om metode. I denne artikkelen vil jeg synliggjøre en tenkemåte fundert i arbeidet med en skjønnlitterær lesesirkel for lærerstudenter, og min egen erfaring som improvisasjonsmusiker. Jazzens begrep om jam blir løftet frem som omdreiningspunkt for tenkemåten, som ellers har sitt teoretiske utspring i den franske filosofen Gilles Deleuze’s forestilling om bliven. Denne vitale forestillingen innebærer at verden produseres kontinuerlig, noe forskeren også bidrar til. Koblingen mellom jam, litteratur og Deleuze synliggjør dessuten en måte å tenke om metode på som understreker at det å forske med kunsten ikke bare betyr å forske på kunsten, men at kunsten på ulike måter kan virke inn på selve forskningen og slik også bidra til å affirmere verden i sin bliven. I tillegg til å tilby en måte å tenke om metode for den som skal forske med kunsten, er hensikten med artikkelen å gjøre forskeren bevisst sin egen tenkning om metode, noe som er viktig siden denne skaper mulighetsbetingelser for metodevalg og -bruk.

  16. Unified transform architecture for AVC, AVS, VC-1 and HEVC high-performance codecs

    Dias, Tiago; Roma, Nuno; Sousa, Leonel

    2014-12-01

    A unified architecture for fast and efficient computation of the set of two-dimensional (2-D) transforms adopted by the most recent state-of-the-art digital video standards is presented in this paper. Contrasting to other designs with similar functionality, the presented architecture is supported on a scalable, modular and completely configurable processing structure. This flexible structure not only allows to easily reconfigure the architecture to support different transform kernels, but it also permits its resizing to efficiently support transforms of different orders (e.g. order-4, order-8, order-16 and order-32). Consequently, not only is it highly suitable to realize high-performance multi-standard transform cores, but it also offers highly efficient implementations of specialized processing structures addressing only a reduced subset of transforms that are used by a specific video standard. The experimental results that were obtained by prototyping several configurations of this processing structure in a Xilinx Virtex-7 FPGA show the superior performance and hardware efficiency levels provided by the proposed unified architecture for the implementation of transform cores for the Advanced Video Coding (AVC), Audio Video coding Standard (AVS), VC-1 and High Efficiency Video Coding (HEVC) standards. In addition, such results also demonstrate the ability of this processing structure to realize multi-standard transform cores supporting all the standards mentioned above and that are capable of processing the 8k Ultra High Definition Television (UHDTV) video format (7,680 × 4,320 at 30 fps) in real time.

    Full Text Available Il contributo propone una lettura delle possibili influenze della realizzazione delle reti AV sulla localizzazione/distribuzione di attività di eccellenza, quali attività direzionali, di management, di servizio alle imprese e alla pubblica amministrazione, con specifico riferimento alla tratta AV Roma-Napoli. A partire da una caratterizzazione delle attività di eccellenza, se ne evidenzia anzitutto la spiccata tendenza alla concentrazione urbana, la dipendenza da efficaci connessioni sia immateriali che materiali e la rilevanza assunta dalla variabile temporale nelle scelte localizzative (Sassen, 2001. Quindi, in riferimento ad alcune esperienze europee, si esaminano i principali effetti, in termini di attrazione/concentrazione di tali attività, connessi alla realizzazione delle reti AV (Sands 1993; Vickerman e Ulied, 2006; Gemeente Amsterdam, 2007. Sulla base di tali considerazioni e tenendo conto delle più recenti definizioni e metodi di misura dell’accessibilità (Axhausen et al. 2006; Spiekermann, Wegener, 2005, lo studio propone un indicatore di “accessibilità” finalizzato ad individuare e graduare, in ragione dei livelli di accessibilità, un sistema di luoghi urbani interconnessi mediante reti su ferro (AV e reti metropolitane e regionali dai quali le attività di eccellenza potranno massimizzare il proprio bacino di utenza. L’individuazione di un sistema di luoghi urbani a diverso grado di accessibilità consente di evidenziare le numerose opportunità per la localizzazione di attività di eccellenza che si dischiudono a seguito della riduzione dei tempi di spostamento consentita dalle reti AV. In tal senso, l’indicatore proposto può costituire un utile supporto alle decisioni sia per l’attore pubblico consentendo di governare e orientare i processi di trasformazione conseguenti alla realizzazione della rete AV, estendendone i benefici dalle aree di stazione a più ampie porzioni urbane sia per l’investitore privato

    Under a recent collaborative effort between the US Army Aeroflightdynamics Directorate (AFDD) and NASA Langley, NASA's general unstructured CFD solver, FUN3D, was modularized as a CREATE-AV Helios near-body unstructured grid solver. The strategies adopted in Helios/FUN3D integration effort are described. A validation study of the new capability is performed for rotorcraft cases spanning hover prediction, airloads prediction, coupling with computational structural dynamics, counter-rotating dual-rotor configurations, and free-flight trim. The integration of FUN3D, along with the previously integrated NASA OVERFLOW solver, lays the ground for future interaction opportunities where capabilities of one component could be leveraged with those of others in a relatively seamless fashion within CREATE-AV Helios.

    [F-18]-AV-1451 is a novel positron emission tomography (PET) tracer with high affinity to neurofibrillary tau pathology in Alzheimer's disease (AD). PET studies have shown increased tracer retention in patients clinically diagnosed with dementia of AD type and mild cognitive impairment in regions that are known to contain tau lesions. In vivo uptake has also consistently been observed in midbrain, basal ganglia and choroid plexus in elderly individuals regardless of their clinical diagnosis, including clinically normal whose brains are not expected to harbor tau pathology in those areas. We and others have shown that [F-18]-AV-1451 exhibits off-target binding to neuromelanin, melanin and blood products on postmortem material; and this is important for the correct interpretation of PET images. In the present study, we further investigated [F-18]-AV-1451 off-target binding in the first autopsy-confirmed Parkinson's disease (PD) subject who underwent antemortem PET imaging. The PET scan showed elevated [F-18]-AV-1451 retention predominantly in inferior temporal cortex, basal ganglia, midbrain and choroid plexus. Neuropathologic examination confirmed the PD diagnosis. Phosphor screen and high resolution autoradiography failed to show detectable [F-18]-AV-1451 binding in multiple brain regions examined with the exception of neuromelanin-containing neurons in the substantia nigra, leptomeningeal melanocytes adjacent to ventricles and midbrain, and microhemorrhages in the occipital cortex (all reflecting off-target binding), in addition to incidental age-related neurofibrillary tangles in the entorhinal cortex. Additional legacy postmortem brain samples containing basal ganglia, choroid plexus, and parenchymal hemorrhages from 20 subjects with various neuropathologic diagnoses were also included in the autoradiography experiments to better understand what [F-18]-AV-1451 in vivo positivity in those regions means. No detectable [F-18]-AV-1451 autoradiographic binding was

    The purpose of this flight test was to measure any differences in pilot-vehicle performance and pilot opinion between the use of the current generation AVS-9 Night Vision Goggle and one variant of the prototype Panoramic Night Vision Goggle (the PNV.GII). The PNVGII has more than double the horizontal field-of-view of the AVS-9, but reduced image quality. The flight path of the AH-1S helicopter was used as a measure of pilot-vehicle performance. Also recorded were subjective measures of flying qualities, physical reserves of the pilot, situational awareness, and display usability. Pilot comment and data indicate that the benefits of additional FOV with the PNVGIIs are to some extent negated by the reduced image quality of the PNVGIIs.

    The Alexander von Humboldt Conference Series of the European Geosciences Union are a series of meetings held outside of Europe, in particular in South America, Africa or Asia, on selected topics of geosciences with a socio-economic impact for regions on these continents, jointly organised with the scientists and their institutes and the institutions of these regions. Given the increasing success of the GIFT workshops held in conjunction with the General Assemblies, since 2010 EGU has also developed a series of GIFT workshops held in conjunction with AvH conferences. Associated GIFT workshops were held in Merida, Yucatan, on the theme of Climate Change, Natural Hazards and Societies (March 2010), then in Penang, Malaysia (June 2011) on the theme of Ocean Acidification, in November 2012 in Cusco (Peru) on the theme of Natural Disasters, Global Change and the Preservation of World Heritage Sites, finally in Istanbul (March 2014) on "High Impact Natural Hazards Related to the Euro-Mediterranean Region. The next GIFT workshop is already planned for October 2015 in Adis Ababa (Ethiopia) on the theme "Water". In each case, the GIFT workshop was held on the last two days of the AvH conference and reunited 40-45 teachers from the nation where the AvH was held. Keynote speakers from AvH were speakers to the GIFT workshops which also included hands-on activities animated by sciences educators. These GIFT workshops represented the first workshops specifically aimed at teachers held in the country, and therefore represents a significant Earth Sciences contribution to secondary education in non European countries.

    Multiple myeloma (MM) is a malignant neoplasm of plasma cells. Although new molecular targeting agents against MM have been developed based on the better understanding of the underlying pathogenesis, MM still remains an incurable disease. We previously demonstrated that β-catenin, a downstream effector in the Wnt pathway, is a potential target in MM using RNA interference in an in vivo experimental mouse model. In this study, we have screened a library of more than 100 000 small-molecule chemical compounds for novel Wnt/β-catenin signaling inhibitors using a high-throughput transcriptional screening technology. We identified AV-65, which diminished β-catenin protein levels and T-cell factor transcriptional activity. AV-65 then decreased c-myc, cyclin D1 and survivin expression, resulting in the inhibition of MM cell proliferation through the apoptotic pathway. AV-65 treatment prolonged the survival of MM-bearing mice. These findings indicate that this compound represents a novel and attractive therapeutic agent against MM. This study also illustrates the potential of high-throughput transcriptional screening to identify candidates for anticancer drug discovery

    A method is presented to evaluate the fractionation of metals (Fe, Zn, Cu, Pb, Cd and Ni), acid volatile sulfide (AVS) and simultaneously extracted metals (SEM) in Edku lagoon sediments. Thirteen sediment samples were collected from the study area in the period of 2010-2011 to assess the potential bioavailability and toxicity of the selected metals. According to classification of the Interim Sediment Quality Quidelines (ISQG), five stations near the drains exhibited 10% toxic probability. The high AVS and low ∑SEM ranges in Summer were identified as 6-138 and 0.86-3.3 µmol g(-1) dry wet, respectively which are referring to the low mobility of heavy metals in this season and vice versa for winter (2.5-23.9 and 1.16-3.82 µmol g(-1) dry wet, respectively). According to the evaluation of USEPA, all sediment samples showed ∑SEM/AVS heavy metals in Edku lagoon sediments posed a low risk of adverse biological effects due to cadmium, copper, lead, nickel and zinc in all evaluated stations.

    2009-01-01

    Full Text Available Los cambios sustantivos en el sistema agroalimentario mexicano han impulsado a las empresas a aplicar estrategias que les permitan funcionar en un contexto cada vez más competitivo, complejo e incierto. En el ramo avícola, Industrias Bachoco ha logrado posicionarse como líder nacional, a pesar de las presiones de la apertura comercial y de la competencia interna de dos de los mayores consorcios avícolas transnacionales. El presente artículo destaca los resultados obtenidos por esta empresa a partir de su estrategia de desplazamiento por la república mexicana. Desde la perspectiva de la teoría de la localización y de la nueva geografía económica, se plantea la hipótesis de que tal estrategia le ha permitido a Bachoco sumar ventajas comparativas regionales y le ha conferido la capacidad de suministrar una oferta adaptada a las costumbres y tradiciones de cada mercado regional, que no ha sido igualada por ninguna de sus competidoras. Se concluye que la apertura total inminente del mercado avícola mexicano inducirá al consorcio a acelerar su actualización, para estar a tono y competir con las empresas internacionales.

    This study presents the development of an efficient procedure for covalently immobilizing collagen molecules on AVS-functionalized Ti-6Al-4V samples, and the assessment of the survival and proliferation of cells cultured on these substrates. Activated Vapor Silanization (AVS) is a versatile functionalization technique that allows obtaining a high density of active amine groups on the surface. A procedure is presented to covalently bind collagen to the functional layer using EDC/NHS as cross-linker. The covalently bound collagen proteins are characterized by fluorescence microscopy and atomic force microscopy and their stability is tested. The effect of the cross-linker concentration on the process is assessed. The concentration of the cross-linker is optimized and a reliable cleaning protocol is developed for the removal of the excess of carbodiimide from the samples. The results demonstrate that the covalent immobilization of collagen type I on Ti-6Al-4V substrates, using the optimized protocol, increases the number of viable cells present on the material. Consequently, AVS in combination with the carbodiimide chemistry appears as a robust method for the immobilization of proteins and, for the first time, it is shown that it can be used to enhance the biological response to the material.

    Surface sediments from the coastal area of the Leizhou Peninsula in the South China Sea were collected and analyzed and the potential ecological risks in the area were assessed based on acid-volatile sulfide (AVS) model. The AVS levels are between 0.109 and 55.6 μmol g(-1), with the average at 4.45 μmol g(-1). The high AVS-concentration zones include the aquaculture areas of Liusha Bay and the densely populated areas of Zhanjiang Bay. The simultaneously extracted metals (SEM) range from 0.026 μmol g(-1) to 8.61 μmol g(-1), with the average at 0.843 μmol g(-1). Most of high SEM-concentration stations were located in ports or aquaculture zones. Most of the coastal surface sediments of the Leizhou Peninsula (90%) had no adverse biological effects according to the criterion proposed by USEPA (2005); while adverse effects were uncertain in some stations (8%); even in 2 stations (2%) adverse biological effects may be expected.

    2014-11-01

    Full Text Available Background: Posterior cortical atrophy (PCA is characterized by progressive higher-order visuoperceptual dysfunction and praxis declines. This syndrome is related to a number of underlying diseases, including, in most cases, Alzheimer's disease (AD. The aim of this study was to compare the amyloid load with 18F-AV45 positron emission tomography (PET between PCA and AD subjects. Methods: We performed 18F-AV45 PET, cerebrospinal fluid (CSF biomarker analysis and a neuropsychological assessment in 11 PCA patients and 12 AD patients. Results: The global and regional 18F-AV45 uptake was similar in the PCA and AD groups. No significant correlation was observed between global 18F-AV45 uptake and CSF biomarkers or between regional 18F-AV45 uptake and cognitive and affective symptoms. Conclusion: This 18F-AV45 PET amyloid imaging study showed no specific regional pattern of cortical 18F-AV45 binding in PCA patients. These results confirm that a distinct clinical phenotype in amnestic AD and PCA is not related to amyloid distribution.

  2. A marked proportional rise in IVC aldosterone following cosyntropin administration during AVS is a signal to the presence of adrenal hyperplasia in primary aldosteronism.

    2014-05-01

    We hypothesized aldosteronoma responsiveness to cosyntropin may be a characterizing feature that could be determined in addition to standard adrenal vein sampling (AVS) data. We reviewed an AVS database from June 2005 to October 2011 including 65 patients with confirmed primary aldosteronism (PA) who underwent AVS and, if applicable, unilateral adrenalectomy. Patients were divided into confirmed lateralized and non-lateralized groups and subgrouped by histology. Plasma aldosterone in inferior vena cava (IVC) pre- and post-cosyntropin infusion during AVS was measured. Peak aldosterone and proportional change was compared between groups. Baseline and peak IVC aldosterone was higher in lateralized patients but incremental aldosterone rise was much greater in subjects with bilateral hyperplasia. From receiver operator characteristics (ROC) analysis, the optimized diagnostic cut point of peak IVC aldosterone of >649 pmol l(-1) would have a sensitivity of 94% for surgical disease although specificity of just 59%. A 250% increase in IVC aldosterone following cosyntropin would be specific enough to exclude 87% of surgical/lateralized disease. These diagnostic capabilities are similar to other results with non-AVS tests performed for diagnosis of lateralization. Although not specific enough to replace standard AVS interpretation, a marked IVC aldosterone increase after cosyntropin during AVS is a useful additional test to diagnose non-lateralizing forms of PA. Such a calculation requires no additional expense or tests.

    2017-04-01

    We examined possible adverse effects of heavy metals on microbial activity, biomass, and community composition using the simultaneously extracted metals (SEM)/acid-volatile sulfide (AVS)-based approach and measurements of exchangeable metal concentrations in three paddy soils (wastewater-contaminated soil, mine-contaminated soil, and noncontaminated soil) incubated for 60 days under flooded conditions. Incubation under flooding increased pH and decreased Eh in all samples. AVS increased when Eh decreased to approximately -200 mV for the mine-contaminated and noncontaminated soils, while the wastewater-contaminated soil originally had a high concentration of AVS despite its air-dried condition. Addition of rice straw or alkaline material containing calcium carbonate and gypsum increased AVS levels under flooded conditions. We observed no apparent relationship between soil enzyme activity (β-D-glucosidase and acid phosphatase) and concentrations of SEM, [∑SEM - AVS], and exchangeable metals. Bacterial and fungal community composition, assessed using polymerase chain reaction-denaturing gradient gel electrophoresis (DGGE) analysis targeting rRNA genes, was largely influenced by site of collection and incubation time, but metal contamination did not influence community composition. We observed significant negative correlations between biomass C and [∑SEM - AVS] and between biomass C and ∑SEM, suggesting that [∑SEM - AVS] and ∑SEM might reflect the bioavailability of organic matter to microorganisms in these soils.

    The vesicular monoamine transporter type 2 (VMAT2) is highly expressed in pancreatic {beta}-cells and thus has been proposed to be a potential target for measuring {beta}-cell mass (BCM) by molecular imaging. C-11- and F-18-labeled tetrabenazine derivatives targeting VMAT2 have shown some promising results as potential biomarkers for BCM. In the present study, we examined the binding characteristics of 9-fluoropropyl-(+)-dihydrotetrabenzazine ([{sup 18}F]AV-133), a potential PET tracer for BCM imaging, in rat pancreas and rat brain. Methods: Pancreatic exocrine cells and pancreatic islet cells were isolated and purified from Sprague-Dawley rats. Membrane homogenates, prepared from both pancreatic exocrine and islet cells as well as from brain striatum and hypothalamus regions, were used for in vitro binding studies. In vitro and ex vivo autoradiography studies with [{sup 18}F]AV-133 were performed on rat brain and rat pancreas sections. Immunohistochemistry studies were performed to confirm the distribution of VMAT2 on islet {beta}-cells. Results: Excellent binding affinities of [{sup 18}F]AV-133 were observed in rat striatum and hypothalamus homogenates with K{sub d} values of 0.19 and 0.25 nM, respectively. In contrast to single-site binding observed in rat striatum homogenates, rat islet cell homogenates showed two saturable binding sites (site A: K{sub d}=6.76 nM, B{sub max}=60 fmol/mg protein; site B: K{sub d}=241 nM, B{sub max}=1500 fmol/mg protein). Rat exocrine pancreas homogenates showed only a single low-affinity binding site (K{sub d}=209 nM), which was similar to site B in islet cells. In vitro autoradiography of [{sup 18}F]AV-133 using frozen sections of rat pancreas showed specific labeling of islets, as evidenced by co-localization with anti-insulin antibody.

    18 F-AV-1451 is currently the most widely used of several experimental tau PET tracers. The objective of this study was to evaluate 18 F-AV-1451 binding with full kinetic analysis using a metabolite-corrected arterial input function and to compare parameters derived from kinetic analysis with SUV ratio (SUVR) calculated over different imaging time intervals. Methods: 18 F-AV-1451 PET brain imaging was completed in 16 subjects: 4 young healthy volunteers (YHV), 4 aged healthy volunteers (AHV), and 8 Alzheimer disease (AD) subjects. Subjects were imaged for 3.5 h, with arterial blood samples obtained throughout. PET data were analyzed using plasma and reference tissue-based methods to estimate the distribution volume, binding potential (BP ND ), and SUVR. BP ND and SUVR were calculated using the cerebellar cortex as a reference region and were compared across the different methods and across the 3 groups (YHV, AHV, and AD). Results: AD demonstrated increased 18 F-AV-1451 retention compared with YHV and AHV based on both invasive and noninvasive analyses in cortical regions in which paired helical filament tau accumulation is expected in AD. A correlation of R 2 > 0.93 was found between BP ND (130 min) and SUVR-1 at all time intervals. Cortical SUVR curves reached a relative plateau around 1.0-1.2 for YHV and AHV by approximately 50 min, but increased in AD by up to approximately 20% at 110-130 min and approximately 30% at 160-180 min relative to 80-100 min. Distribution volume (130 min) was lower by 30%-35% in the YHV than AHV. Conclusion: Our data suggest that although 18 F-AV-1451 SUVR curves do not reach a plateau and are still increasing in AD, an SUVR calculated over an imaging window of 80-100 min (as currently used in clinical studies) provides estimates of paired helical filament tau burden in good correlation with BP ND , whereas SUVR sensitivity to regional cerebral blood changes needs further investigation. © 2017 by the Society of Nuclear Medicine and

    Cerebral glucose metabolism measured with [18F]-FDG PET is a well established marker of neuronal dysfunction in neurodegeneration. The tau-protein tracer [18F]-AV-1451 PET is currently under evaluation and shows promising results. Here, we assess the feasibility of early perfusion imaging with AV-1451 as a substite for FDG PET in assessing neuronal injury. Twenty patients with suspected neurodegeneration underwent FDG and early phase AV-1451 PET imaging. Ten one-minute timeframes were acquired after application of 200 MBq AV-1451. FDG images were acquired on a different date according to clinical protocol. Early AV-1451 timeframes were coregistered to individual FDG-scans and spatially normalized. Voxel-wise intermodal correlations were calculated on within-subject level for every possible time window. The window with highest pooled correlation was considered optimal. Z-transformed deviation maps (ZMs) were created from both FDG and early AV-1451 images, comparing against FDG images of healthy controls. Regional patterns and extent of perfusion deficits were highly comparable to metabolic deficits. Best results were observed in a time window from 60 to 360 s (r = 0.86). Correlation strength ranged from r = 0.96 (subcortical gray matter) to 0.83 (frontal lobe) in regional analysis. ZMs of early AV-1451 and FDG images were highly similar. Perfusion imaging with AV-1451 is a valid biomarker for assessment of neuronal dysfunction in neurodegenerative diseases. Radiation exposure and complexity of the diagnostic workup could be reduced significantly by routine acquisition of early AV-1451 images, sparing additional FDG PET. (orig.)

The aim of this paper is on what focus a new scientific discipline as nursing science has developed through the thesis, and how it constitutes during a certain amount of time. The article starts with a presentation of themes and the basis of recognition. Then philosophy of science and methodologies that are the dominant tendencies will be discussed related to the historical origin of nursing science at the University of Bergen. The empirical theoretical and methodological approach is based upon the theory of the French sociologist Pierre Bourdieu about understanding current practices in light of historical origin. Results: Majority uses qualitative method (71.4%, and is using phenomenological and hermeneutical approaches. The quantitative tasks (26.2% are mainly anchored in medical terminology and are using medical statistics. Issues are mainly from the nurses own practices and practical utility are emphasized. Only one work is using mixed methods. Questions that will be discussed are why these master-thesis materialize in the way they do, and what kind of factors that influence opportunities and choices in nursing science?

    Full Text Available Objetivo: caracterizar las granjas avícolas y la autosuficiencia de maíz y soya, en Tungurahua-Ecuador. Metodología: se realizaron entrevistas a noventa avicultores seleccionados mediante muestreo no probabilístico; se utilizó estadísticas de producción y exportaciones reportadas por la Asociación de Fabricantes de Balanceados (AFABA y el Ministerio de Agricultura, Ganadería, Acuacultura y Pesca (MAGAP, y se calcularon índices de Tasa Media de Variación Acumulada y autosuficiencia y dependencia alimentaria. Resultados: en Tungurahua el 78% de avicultores se dedican a la crianza de aves de postura y el 62% tienen instalaciones semiautomatizadas. El 100% de maíz y soya utilizado por la avicultura de Tungurahua, procede de otras provincias e importaciones internacionales. Entre el 2007 y 2016, el maíz registró un índice de autosuficiencia promedio anual de 0.9, mientras que la soya registró 0.08. Limitaciones: la información estadística de producción nacional e importaciones de granos se encontró dispersa. Conclusiones: los resultados indican la presencia de diversos tipos de sistemas de producción avícola. Éstos, según el nivel tecnológico, van desde los artesanales hasta los automatizados. Así mismo, la producción nacional alcanza a cubrir con dificultad la demanda nacional del sector avícola, no así la soya nacional que cubre una mínima parte. Con base en éstos resultados se sugiere mantener la política de sustitución de importaciones de maíz amarillo y ampliar a la soya.

    A number of studies argue in favour of an important role of microbial colonization, in particular of Staphylococcus aureus, in triggering atopic dermatitis (AD) flare-up and psoriasis, in particular through the superantigenic properties of toxins generated by S. aureus. The aim of this study was to assess the efficacy of a 3-week Avène hydrotherapy on the skin surface of patients suffering from psoriasis or atopic dermatitis. Skin samples were taken from healthy subjects or atopic (n = 18) or psoriatic patients (n = 39) undergoing hydrotherapy at Avène at the beginning (D0) and the end of treatment (D18). The severity of the dermatosis was evaluated according to SCORing Atopic Dermatitis (SCORAD) or Psoriasis Area Severity Index (PASI) scores at D0 and D18. Marker of inflammation interleukin 8 (IL-8), S. aureus colonization (protein A) and enterotoxins were assessed in skin samples using RT-PCR. At D0, significant differences were observed between healthy subjects and atopic or psoriatic patients in all the parameters evaluated (IL-8, protein A). At the end of the hydrotherapy, a significant decrease in SCORAD was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin D in patients with atopic dermatitis. Similarly, a significant decrease in PASI was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin N in patients with psoriasis. This study demonstrates the positive effects of Avène hydrotherapy on the skin of patients suffering from chronic dermatosis, with decreased inflammation and reduced colonization by S. aureus. © 2010 The Authors.

    18 F-9-fluoropropyl-(+)-dihydrotetrabenazine ( 18 F-AV-133) is a novel positron emission tomography tracer for imaging the vesicular monoamine transporter II in dopaminergic neuron degeneration, which might be indicative for Parkinson's disease (PD) and other parkinsonism. Studies were performed to optimize the imaging time window for calculating standardized uptake value ratio (SUVR) with correlation to distribution volume ratio (DVR) and in differentiating PD from normal controls (NCs). Methods: Thirteen 18 F-AV-133 positron emission tomography studies were conducted on four NCs (age, 62.3±4.9 years) and nine PD patients (age, 60.8±6.0 years) with Hoehn and Yahr stages 2 to 3. Dynamic images were acquired within 180 min (0–30, 50–140 and 160–180 min) and were rearranged into 14 of 10-min scans. The contralateral striatum was defined as the opposite striatum to the predominantly affected limbs. Volumes of interest (VOIs) of bilateral putamen, caudate nuclei and occipital cortex (OC; as the reference region) were delineated from individual magnetic resonance imaging. SUVRs of striatum to OC were computed from 14 dynamic image sets. The DVRs were computed from Logan graphic analysis by using OC as the input. The performance of SUVR was evaluated based on the correlation of SUVR at each time window to DVR, as well as the Cohen effect size (group mean SUVR difference between PD and NC/standard deviation). Results: 18 F-AV-133 uptake decreased in PD subjects at bilateral striatum especially at contralateral side with posterior putamen predominant as compared with NC. Consistent higher correlations of SUVRs to DVR for all VOIs were observed at later time window and reached to its maximal value of 0.9917 at 90–100 min. The group mean SUVR differences between NC and PD subjects increased and reached relatively stable values after 90 min. The effect sizes for all VOIs were stable across different time window and with the largest value around 90∼120 min

  15. Innføringen av de norske lovene på Island i perioden 1274-1319

    OpenAIRE

    Smerud, Bjørn Gunnar

    2013-01-01

    I 1274 fikk Magnus VI Håkonsson innført en landsdekkende lovbok i Norge, kalt Landsloven. Han ønsket også å innføre lignende lovbøker i skattlandene som var blitt underlagt den norske kronen i perioden før hans regjeringstid. I denne oppgaven ser jeg nærmere på hvordan dette ble gjort på Island i perioden mellom 1274 og 1319. Dette gjøres gjennom en grundig sammenligning av den norske Landsloven og Jónsbók, den islandske versjonen fra 1281.

    Robust sediment quality criteria require chemistry and toxicity data predictive of concentrations where population/community response should occur under known geochemical conditions. Understanding kinetic and geochemical effects on toxicant bioavailability is key, and these are influenced by infaunal sediment bioturbation. This study used fine-scale sediment and porewater measurement of contrasting infaunal effects on carbon-normalized SEM-AVS to evaluate safe or potentially toxic nickel concentrations in a high-binding Spartina saltmarsh sediment (4%TOC; 35-45 μmol-S2-·g(-1)). Two crustaceans producing sharply contrasting bioturbation--the copepod Amphiascus tenuiremis and amphipod Leptocheirus plumulosus--were cultured in oxic to anoxic sediments with SEM[Ni]-AVS, TOC, porewater [Ni], and porewater DOC measured weekly. From 180 to 750 μg-Ni·g(-1) sediment, amphipod bioturbation reduced [AVS] and enhanced porewater [Ni]. Significant amphipod uptake, mortality, and growth-depression occurred at the higher sediment [Ni] even when [SEM-AVS]/foc suggested acceptable risk. Less bioturbative copepods produced higher AVS and porewater DOC but exhibited net population growth despite porewater [Ni] 1.3-1.7× their aqueous [Ni] LOEC. Copepod aqueous tests with/without dissolved organic matter showed significant aqueous DOC protection, which suggests porewater DOC attenuates sediment Ni toxicity. The SEM[Ni]-AVS relationship was predictive of acceptable risk for copepods at the important population-growth level.

    Supraventricular arrhythmias (junctional ectopic tachycardia [JET] and atrial tachyarrhythmias) frequently complicate recovery from open heart surgery in children and can be difficult to manage. Medical treatment of JET can result in significant morbidity. Our goal was to develop a nonpharmacological approach using autonomic stimulation of selective fat pad (FP) regions of the heart in a young canine model of open heart surgery to control 2 common postoperative supraventricular arrhythmias. Eight mongrel dogs, varying in age from 5 to 8 months and weighting 22±4 kg, underwent open heart surgery replicating a nontransannular approach to tetralogy of Fallot repair. Neural stimulation of the right inferior FP was used to control the ventricular response to supraventricular arrhythmias. Right inferior FP stimulation decreased baseline AV nodal conduction without altering sinus cycle length. AV node Wenckebach cycle length prolonged from 270±33 to 352±89 ms, P=0.02. Atrial fibrillation occurred in 7 animals, simulating a rapid atrial tachyarrhythmias. FP stimulation slowed the ventricular response rate from 166±58 to 63±29 beats per minute, Popen heart surgery model. FP stimulation may be a useful new technique for managing children with JET and atrial tachyarrhythmias.

    Full Text Available Artikkelen presenterer en mikro-etnografisk undersøkelse av barns forhold til tingene i to småbarnsavdelinger i norske barnehager. Hensikten er å forstå hvordan barns relasjoner til ting virker inn på deres mulighet til deltagelse og sosial posisjonering i gruppen. Undersøkelsen er basert på Aktør-Nettverk-Teori som vektlegger tingenes betydning som agens i sosiale nettverk og tingenes funksjon som forlengelse av barnas kropper. Undersøkelsen viser at tingene har betydning som legitim inngangsbillett til deltagelse i lekegrupper og at tingenes innbyrdes hierarkiske orden bidrar i å uttrykke den sosiale orden mellom barna som inngår i relasjon med dem. The article presents a micro-ethnographic study on toddlers’ relationship to the material artefacts in two Norwegian kindergarten groups. The purpose of the study is to understand how their relationship with objects influences their possibilities for participation in peer groups. The study is based on Actor-Network-Theory. A main point is that material artefacts have agency in social networks surrounding us and function as extensions of our bodies. The study indicates that material artefacts serve as entrance tickets for participation in group activities and that the hierarchic order between the objects in the room, influences the social order among the children using them.

    A laboratory bioassay determined the relative contribution of various pathways of Ag, Cd and Zn bioaccumulation in the marine polychaete Neanthes arenaceodentata exposed to moderately contaminated sediments. Juvenile worms were exposed for 25 d to experimental sediments containing 5 different reactive sulfide (acid volatile sulfides, AVS) concentrations (1 to 30 ??mol g-1), but with constant Ag, Cd, and Zn concentrations of 0.1, 0.1 and 7 ??mol g-1, respectively. The sediments were supplemented with contaminated food (TetraMin??) containing 3 levels of Ag-Cd-Zn (uncontaminated, 1?? or 5??1 metal concentrations in the contaminated sediment). The results suggest that bioaccumulation of Ag, Cd and Zn in the worms occurred predominantly from ingestion of contaminated sediments and contaminated supplementary food. AVS or dissolved metals (in porewater and overlying water) had a minor effect on bioaccumulation of the 3 metals in most of the treatments. The contribution to uptake from the dissolved source was most important in the most oxic sediments, with maximum contributions of 8% for Ag, 30% for Cd and 20% for Zn bioaccumulation. Sediment bioassays where uncontaminated supplemental food is added could seriously underestimate metal exposures in an equilibrated system; N. arenaceodentata feeding on uncontaminated food would be exposed to 40-60% less metal than if the food source was equilibrated (as occurs in nature). Overall, the results show that pathways of metal exposure are dynamically linked in contaminated sediments and shift as external geochemical characteristics and internal biological attributes vary.

    Av3 is a short peptide toxin from the sea anemone Anemonia viridis shown to be active on crustaceans and inactive on mammals. It inhibits inactivation of Na(v)s (voltage-gated Na+ channels) like the structurally dissimilar scorpion alpha-toxins and type I sea anemone toxins that bind to receptor site-3. To examine the potency and mode of interaction of Av3 with insect Na(v)s, we established a system for its expression, mutagenized it throughout, and analysed it in toxicity, binding and electrophysiological assays. The recombinant Av3 was found to be highly toxic to blowfly larvae (ED50=2.65+/-0.46 pmol/100 mg), to compete well with the site-3 toxin LqhalphaIT (from the scorpion Leiurus quinquestriatus) on binding to cockroach neuronal membranes (K(i)=21.4+/-7.1 nM), and to inhibit the inactivation of Drosophila melanogaster channel, DmNa(v)1, but not that of mammalian Na(v)s expressed in Xenopus oocytes. Moreover, like other site-3 toxins, the activity of Av3 was synergically enhanced by ligands of receptor site-4 (e.g. scorpion beta-toxins). The bioactive surface of Av3 was found to consist mainly of aromatic residues and did not resemble any of the bioactive surfaces of other site-3 toxins. These analyses have portrayed a toxin that might interact with receptor site-3 in a different fashion compared with other ligands of this site. This assumption was corroborated by a D1701R mutation in DmNa(v)1, which has been shown to abolish the activity of all other site-3 ligands, except Av3. All in all, the present study provides further evidence for the heterogeneity of receptor site-3, and raises Av3 as a unique model for design of selective anti-insect compounds.

    Tau accumulation is a core pathologic change in various neurodegenerative diseases including Alzheimer's disease and frontotemporal lobar degeneration-tau. Recently, tau positron emission tomography tracers such as [ 18 F] AV-1451 and [ 18 F] THK5351 have been developed to detect tau deposition in vivo. In the present study, we performed a head to head comparison of these two tracers in Alzheimer's disease and frontotemporal dementia cases and aimed to investigate which tracers are better suited to image tau in these disorders. A cross-sectional study was conducted using a hospital-based sample at a tertiary referral center. We recruited eight participants (two Alzheimer's disease, four frontotemporal dementia and two normal controls) who underwent magnetic resonance image, amyloid positron emission tomography with [ 18 F]-Florbetaben and tau positron emission tomography with both THK5351 and AV-1451. To measure regional AV1451 and THK5351 uptakes, we used the standardized uptake value ratios by dividing mean activity in target volume of interest by mean activity in the cerebellar hemispheric gray matter. Although THK5351 and AV-1451 uptakes were highly correlated, cortical uptake of AV-1451 was more striking in Alzheimer's disease, while cortical uptake of THK5351 was more prominent in frontotemporal dementia. THK5351 showed higher off-target binding than AV-1451 in the white matter, midbrain, thalamus, and basal ganglia. AV-1451 is more sensitive and specific to Alzheimer's disease type tau and shows lower off-target binding, while THK5351 may mirror non-specific neurodegeneration. (orig.)

    To determine if peripheral neuropathology exists among the innervation of cutaneous arterioles and arteriole-venule shunts (AVS) in fibromyalgia (FM) patients. Cutaneous arterioles and AVS receive a convergence of vasoconstrictive sympathetic innervation, and vasodilatory small-fiber sensory innervation. Given our previous findings of peripheral pathologies in chronic pain conditions, we hypothesized that this vascular location may be a potential site of pathology and/or serotonergic and norepinephrine reuptake inhibitors (SNRI) drug action. Twenty-four female FM patients and nine female healthy control subjects were enrolled for study, with 14 additional female control subjects included from previous studies. AVS were identified in hypothenar skin biopsies from 18/24 FM patient and 14/23 control subjects. Multimolecular immunocytochemistry to assess different types of cutaneous innervation in 3 mm skin biopsies from glabrous hypothenar and trapezius regions. AVS had significantly increased innervation among FM patients. The excessive innervation consisted of a greater proportion of vasodilatory sensory fibers, compared with vasoconstrictive sympathetic fibers. In contrast, sensory and sympathetic innervation to arterioles remained normal. Importantly, the sensory fibers express α2C receptors, indicating that the sympathetic innervation exerts an inhibitory modulation of sensory activity. The excessive sensory innervation to the glabrous skin AVS is a likely source of severe pain and tenderness in the hands of FM patients. Importantly, glabrous AVS regulate blood flow to the skin in humans for thermoregulation and to other tissues such as skeletal muscle during periods of increased metabolic demand. Therefore, blood flow dysregulation as a result of excessive innervation to AVS would likely contribute to the widespread deep pain and fatigue of FM. SNRI compounds may provide partial therapeutic benefit by enhancing the impact of sympathetically mediated inhibitory

    Amyloid-β (Aβ), tau, and cerebral small vessel disease (CSVD), which occasionally coexist, are the most common causes of cognitive impairments in older people. However, whether tau is observed in patients with subcortical vascular cognitive impairment (SVCI), as well as its associations with Aβ and CSVD, are not yet established. More importantly, the role of tau underlying cognitive impairments in SVCI is unknown. To investigate the extent and the role of tau in patients with SVCI using 18F-AV1451, which is a new ligand to detect neurofibrillary tangles in vivo. This cross-sectional study recruited 64 patients with SVCI from June 2015 to December 2016 at Samsung Medical Center, Seoul, Korea. The patients had significant ischemia on brain magnetic resonance imaging, defined as periventricular white matter hyperintensity at least 10 mm and deep white matter hyperintensity at least 25 mm. We excluded 3 patients with SVCI owing to segmentation error during AV1451 positron emission tomography analysis. We calculated CSVD scores based on the volumes of white matter hyperintensities, numbers of lacunes, and microbleeds using magnetic resonance imaging data. The presence of Aβ was assessed using fluorine 18-labeled (18F) florbetaben positron emission tomography. Tau was measured using 18F-AV1451 positron emission tomography. We determined the spreading order of tau by sorting the regional frequencies of cortical involvement. We evaluated the complex associations between Aβ, CSVD, AV1451 uptake, and cognition in patients with SVCI. Of the 61 patients with SVCI, 44 (72.1%) were women and the mean (SD) age was 78.7 (6.3) years. Patients with SVCI, especially patients with Aβ-negative SVCI, showed higher AV1451 uptake in the inferior temporal areas compared with normal control individuals. In patients with SVCI, Aβ positivity and CSVD score were each independently associated with increased AV1451 uptake in the medial temporal and inferior temporal regions, respectively

    Full Text Available Under senare år har studenters läraromdömen allt mer hamnat i fokus inom skola såväl som högre utbildning. Parallellt med dessa utvecklingar har olika typer av internettjänster genom vilka studenter kan betygsätta sina lärare dykt upp i flera länder. I Sverige lanserades 2008 tjänsten ”Studenter tycker till” (STT där studenter kan registrera sig och fylla i bedömningar av lärare enligt kriterierna utlärningsförmåga, kunskap, engagemang och lärandestöd. I denna studie undersöks betydelsen av lärarens kön och ålder för studenters läraromdömen genom en kvantitativ analys av omdömen av 98 högskole- och universitetslärare som givits på hemsidan STT. Syftet är att synliggöra hur sociala markörer, i detta fall om läraren är man eller kvinna, ung eller gammal, spelar en stor roll för hur en lärare utvärderas. Resultaten visar att kvinnor och unga lärare systematiskt ges lägre betyg av studenter, än män och äldre lärare. Studenter är således inte könsblinda eller oberoende av föreställningar om förhållandet mellan ålder och kompetens i sina bedömningar. Studien aktualiserar betydelsen av sociala markörer så som kön och ålder måste synliggöras och tas i beaktning när studenters utvärderingar av lärare och kurser behandlas inom högre utbildning.

    The acid-volatile sulfide (AVS), simultaneously extracted metals (SEM), total metals, and pore-water metal concentrations were studied in Vojvodina (Serbia) sediments. In Serbia, there are no regulations concerning sediment quality standards and sediment management. Harmonization of legislation in the domain of environmental protection with EU requirements will increase the significance of the sediment issue. Sediment quality was assessed according to Dutch standards, but the results were also compared with Canadian and USEPA (United States Environmental Protection Agency) guidelines for sediment quality. A comparison of the results based on different criteria for sediment quality assessment shows that they are sometimes contradictory. Therefore, a single approach to quality assessment may be insufficient. The Sigma[SEM]/[AVS] ratio was found to be greater than one at several locations that were already recognized as places of high risk based on Dutch standards. Some other samples had Sigma[SEM]/[AVS]AVS]>1 can cause increased toxicity because there are many other metal-binding phases in sediments. Metals that are associated with AVS may be released within sediments through storms, dredging activities, oxidation, etc., and may have adverse environmental impacts. This has to be taken into account during dredging, which is for some sediments necessary because the sediment is of class 4 (Dutch evaluation), because the dredging process will certainly increase the concentration of bioavailable heavy metals and disturb the sedimentation dynamics. The obtained results will be invaluable for future activities regarding dredging and sediment management in the country.

    Full Text Available Este trabajo plantea la construcción de un índice de competitividad para el sector avícola colombiano. Para construir el índice compuesto de competitividad se propusieron, mediante análisis de componentes principales (ACP, cuatro dimensiones que explican la competitividad. Estas dimensiones son: conocimiento (IC: 33,62%, dimensión productiva (IP: 26,94%, dimensión económica (IE: 26,84% y dimensión tecnológica (IT: 12,57%. Se encontró que las regiones más competitivas en 2002 fueron, en orden descendente: Santander, Boyacá, Cundinamarca y Antioquia. Se puede concluir que la competitividad es un fenómeno multidimensional y que las variables asociadas con el origen de los recursos económicos estuvieron estrechamente relacionadas con las otras variables consideradas.

  16. Low Cost Design of a Hybrid Architecture of Integer Inverse DCT for H.264, VC-1, AVS, and HEVC

    2012-01-01

    Full Text Available The paper presents a unified hybrid architecture to compute the 8×8 integer inverse discrete cosine transform (IDCT of multiple modern video codecs—AVS, H.264/AVC, VC-1, and HEVC (under development. Based on the symmetric structure of the matrices and the similarity in matrix operation, we develop a generalized “decompose and share” algorithm to compute the 8×8 IDCT. The algorithm is later applied to four video standards. The hardware-share approach ensures the maximum circuit reuse during the computation. The architecture is designed with only adders and shifters to reduce the hardware cost significantly. The design is implemented on FPGA and later synthesized in CMOS 0.18 um technology. The results meet the requirements of advanced video coding applications.

    2017-04-01

    The subseasonal predictability of low-frequency modes and the atmospheric circulation regimes is investigated based on the using of outputs from global Semi-Lagrangian (SL-AV) model of the Hydrometcentre of Russia and Institute of Numerical Mathematics of Russian Academy of Science. Teleconnection indices (AO, WA, EA, NAO, EU, WP, PNA) are used as the quantitative characteristics of low-frequency variability to identify zonal and meridional flow regimes with focus on control distribution of high impact weather patterns in the Northern Eurasia. The predictability of weekly and monthly averaged indices is estimated by the methods of diagnostic verification of forecast and reanalysis data covering the hindcast period, and also with the use of the recommended WMO quantitative criteria. Characteristics of the low frequency variability have been discussed. Particularly, it is revealed that the meridional flow regimes are reproduced by SL-AV for summer season better comparing to winter period. It is shown that the model's deterministic forecast (ensemble mean) skill at week 1 (days 1-7) is noticeably better than that of climatic forecasts. The decrease of skill scores at week 2 (days 8-14) and week 3( days 15-21) is explained by deficiencies in the modeling system and inaccurate initial conditions. It was noticed the slightly improvement of the skill of model at week 4 (days 22-28), when the condition of atmosphere is more determined by the flow of energy from the outside. The reliability of forecasts of monthly (days 1-30) averaged indices is comparable to that at week 1 (days 1-7). Numerical experiments demonstrated that the forecast accuracy can be improved (thus the limit of practical predictability can be extended) through the using of probabilistic approach based on ensemble forecasts. It is shown that the quality of forecasts of the regimes of circulation like blocking is higher, than that of zonal flow.

    Α limited number of genetic variants have been linked to the development of intracerebral hemorrhage (ICH). Ιntegrin AV and/or B8-deficient mice were found to develop ICH. The present candidate gene association study was designed to investigate possible influence of integrin AV (ITGAV) and integrin B8 (ITGB8) gene region polymorphisms on the risk of ICH. 1015 participants (250 Greek and 193 Polish patients with primary ICH and 250 Greek and 322 Polish controls) were included in the study. Using logistic regression analyses, 11 tag single nucleotide polymorphisms (SNPs) for ITGAV and 11 for ITGB8 gene were tested for associations with ICH risk, lobar ICH risk and non-lobar ICH after adjustment for age, gender, history of hypertension and country of origin. Linear regression models were used to test the effect of tag SNPs on the ICH age of onset. Correction for multiple comparisons was carried out. The rs7565633 tag SNP of the ITGAV gene was independently associated with the risk of lobar ICH in the codominant model of inheritance [odds ratio (95 % confidence interval (CI)) 0.56 (0.36-0.86), p = 0.0013]. Furthermore, heterozygous individuals of the rs10251386 and the rs10239099 of the ITGB8 gene had significantly lower age of ICH onset compared to the wild-type genotypes [regression coefficient (b) -3.884 (95 % CI -6.519, -1.249), p = 0.0039 and b = -4.502 (95 % CI -7.159, -1.845), p = 0.0009, respectively]. The present study provides preliminary indication for an influence of ITGAV gene tag SNP in the development of lobar ICH and of ITGB8 gene variants in the age of ICH onset.

    Sediments from the Pialassa Piomboni coastal lagoon (NE Italy) were studied to assess the degree of contamination and ecological risk related to trace metals by combining a geochemical characterization of bulk sediments with the assessment of the bioavailable forms of trace metals. With this purpose, sediment contamination (Cd, Cu, Hg, Ni, Pb, and Zn) was assessed by Enrichment Factors (EFs), and potential bioavailability by the Simultaneously Extracted Metals and Acid Volatile Sulfides (SEM-AVS) approach (Cd, Cu, Ni, Pb, and Zn), and by Sequential Extraction Procedure (Co, Cr, Cu, Ni, Pb, and Zn). On average, Cr and Ni exhibited no contamination (EF ≤1.5), and a predominance in the residual fraction of the sediment, indicating natural origin for these metals. Cu, Pb and Zn displayed a local contamination, which resulted in a higher proportion of Cu bound to the reducible and oxidizable fractions (~30% and ~40% as median, respectively), and Pb mostly associated with the reducible phase (~60% as median). Hence, Cu and Pb could be mobilized when environmental conditions become reducing or oxidizing. Zn resulted mainly partitioned into the reducible and residual fractions (~50% as median, in both fractions). The Risk Assessment Code (RAC) indicated that approximately 30% of samples had >10% of total Zn weakly bound to the sediment, suggesting a medium risk of exposure for aquatic organisms. RAC results were consistent with the ∑SEM-AVS findings, pointing to possible adverse effects for aquatic biota in ~30% of samples, with Zn mostly accounting for the total metal bioavailability. Hg showed a moderate to very severe enrichment, indicating that a substantial amount of this metal derives from anthropogenic sources and may pose adverse effects on the aquatic biota of the Pialassa Piomboni lagoon.

  6. Differences in SEM-AVS and ERM-ERL predictions of sediment impacts from metals in two US Virgin Islands marinas.

    Science.gov (United States)

    Hinkey, Lynne M; Zaidi, Baqar R

    2007-02-01

    Two US Virgin Islands marinas were examined for potential metal impacts by comparing sediment chemistry data with two sediment quality guideline (SQG) values: the ratio of simultaneously extractable metals to acid volatile sulfides (SEM-AVS), and effects range-low and -mean (ERL-ERM) values. ERL-ERMs predicted the marina/boatyard complex (IBY: 2118 microg/g dry weight total metals, two exceeded ERMs) would have greater impacts than the marina with no boatyard (CBM: 231 microg/g dry weight total metals, no ERMs exceeded). The AVS-SEM method predicted IBY would have fewer effects due to high AVS-forming metal sulfide complexes, reducing trace metal bioavailability. These contradictory predictions demonstrate the importance of validating the results of either of these methods with other toxicity measures before making any management or regulatory decisions regarding boating and marina impacts. This is especially important in non-temperate areas where sediment quality guidelines have not been validated.

    The AVS-F apparatus (Russian abbreviation for Amplitude-Time Spectrometry of the Sun) is intended for the solar flares' hard X-ray and gamma-ray emission characteristic studies and for the search and detection of the gamma-ray bursts (GRB). At present over 1,100 events with duration more than 2 s without any coordinate relations to Earth Radiation Belts and South Atlantic Anomaly were separated on the results of preliminary analysis of AVS-F experiment database.About 68 % of the identified events were associated with quasistationary equatorial precipitations-15-30 % count rate increases in the low-energy gamma-band of the AVS-F apparatus over its average value obtained by approximation of these parts with polynomials discovered on some equatorial segments in the ranges of geographic latitude of 25∘ up to +30∘. Several short events with duration of 1-16 ms associated with terrestrial gamma-ray flashes were registered during the experiment. These events were detected above the powerful thunderstorm formations.Solar flares with classes stronger than M1.0 according to the GOES classification were about 7 % of the detected events. Solar flares' hard X-rays and γ-emission were mainly observed during the rise or maximum phases of the emission in the soft X-rays band according to the detectors on board the GOES series satellites data and duration of their registration is less than of the soft X-ray bands. According to the preliminary data analysis gamma-emission with energy over 10 MeV was registered during 12 % of the observed flares. The emission in the energy band E ¿ 100 keV was registered during over 60 faint solar flares (of B and C classes according to the GOES and from several ones γ-quanta with energy up to several tens of MeV were observed.Several spectral line complexes were observed in the spectra of some solar flares stronger than M1.0 in the low-energy gamma-range.

    Full Text Available Migranter som fortsetter å oppholde seg i et land etter avslag på søknad om opphold, eller som unnlater å søke om oppholdstillatelse, utfordrer det juridiske rammeverket for nasjonalstater og statsborgerskap. I denne artikkelen diskuteres livssituasjonen til migranter uten lovlig opphold opp mot normativ kosmopolitisk teori om universelle rettigheter. Dette er belyst i internasjonal litteratur, men i mindre grad innenfor en norsk kontekst. Vi tar i denne artikkelen for oss tre empiriske eksempler: tilværelsen i såkalte ventemottak, tilværelsen utenfor ventemottakene og tilværelsen for barn uten lovlig opphold. Gjennom eksemplene diskuterer vi rettighetsspørsmål i migrantenes liv. Vi viser hvordan menneskerettighetene ikke er tilstrekkelige for å ivareta migrantenes velvære, og hvordan rettigheter migrantene faktisk har, ikke fremstår som reelle fordi det oppleves som risikabelt å benytte seg av dem. Artikkelen setter normativ kosmopolitisk teori i perspektiv ved å diskutere den konkrete situasjonen til migrantene, og spør til slutt hva som kan være konsekvensene av at rettigheter blir ulikt fordelt?Nøkkelord: rettferdighet, rettigheter, migrasjon, ulovlig opphold, kosmopolitismeEnglish summary: Without legal residency = no rights?

  16. The Abundances of the Fe Group Elements in AV 304, an Abundance Standard in the Small Magellanic Cloud

    AV 304 is a B0.5 IV field star in the Small Magellanic Cloud with ultra-sharp spectral lines that has emerged as an abundance standard. We have combined recent spectroscopic observations from the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope with archival data from the Far Ultraviolet Spectroscopic Explorer (FUSE) and ESO’s VLT/UVES to determine the abundances of the Fe group elements (Ti, V, Cr, Mn, Fe, Co, & Ni). The analysis was carried through using the Hubeny/Lanz NLTE programs TLUSTY/SYNSPEC. The COS observations were secured with the G130M, G160M, G185M, and G225M gratings. Combined with the FUSE data, we have achieved spectral coverage in the UV from 950 to 2400 A. Measurable lines from the Fe group, except for a very few multiplets of Fe II, III are not observed in optical spectra. The following stellar parameters were found: Teff = 27500±500 K, log g = 3.7±0.1 cm/s2, Vturb= 1±1 km/s, and v sin i = 8 ±2 km/s. The Fe abundance appears to be only slightly lower than the mean depletion in the SMC, but the other Fe group elements are underabundant by 0.3 dex or more. This study confirmed the low abundance of nitrogen (-1.25 dex relative to the solar value) that was reported by Peters & Adelman (ASP Conf. Series, 348, p. 136, 2006). Whereas the light elements are delivered to the ISM by core-collapse supernovae (CCSNe), the Fe group elements are believed to come mostly from low/intermediate mass binaries containing white dwarfs that undergo SNe Ia explosions. A single SNe Ia can deliver 0.5 solar masses of pure Fe (and maybe Mn) to the ISM compared with about 0.07 solar masses from a CCSNe. It appears that there is very little processed material from its interior in the atmosphere of AV 304 and that the star did not form from an interstellar cloud that was enriched by material from earlier supernova activity.

    Full Text Available I prosjektet «Kontinuitet i omsorgen gjennom svangerskap, fødsel og barseltid» var målet å få kunnskap om hvorvidt en slik modell i de praktiske studiene ville gi jordmorstudentene en økt forståelse for jordmorfaget, med vekt på å fremme et normalt svangerskap, fødsel og barseltid. Målsettingen med dette vitenskapelige essayet er å sette prosjektet inn i en pedagogisk referanseramme, der jordmorstudentenes læreprosess og den grunnleggende forståelsen for jordmorfaget ses i lys av ulike læringsteorier. Jordmorstudentenes læring kan settes i et overordnet konstruktivistisk og sosiokulturelt perspektiv. Carl Rogers teori om relasjonens betydning som en forutsetning for å utvikle personlig vekst og modenhet er sentral. Helhetlig læring er en prosess som berører hele mennesket i interaksjon med sine omgivelser, og i denne betydningen inkluderer læring utvikling av relasjoner. Det var nyttig å benytte Carr og Kemmis modell som et verktøy for å analysere aksjonslæringsprosessen, siden denne modellen tar hensyn til den sosiale dimensjonen med samhandling mellom aktørene. Summary In the project «Continuity of care during pregnancy, childbirth and the postnatal period», the objective was to gain insight into whether the outlined model of care in practical studies would increase student midwives’ understanding of midwifery when the emphasis was on the promotion of normal pregnancy, childbirth and the postnatal period. The aim of this scientific essay is to put the project into a pedagogic framework in which the student midwives’ learning process and fundamental understanding of midwifery are viewed in the light of different learning theories. The learning of student midwives can be studied through constructivist and socio-cultural perspectives. Carl Roger's theory of the significance of relationships for achieving personal growth and maturity is essential. Holistic learning is a process that emphasizes the human wholeness in
