This policy is based on programs, actions and strategies that aim to insert the families in the production process, making them suitable to the market system. At the same time it denies the peasant rationality, it hides structural issues of the field, such as the need for land reform, exploitation and expropriation of the wealth and conflicts (reexistents. In order to handle and analyze such issues, highlighting the conflicts surrounding the relation between public policy and peasant families, it was analyzed the processes of implementation of the Production and Use of Biodiesel National Program (PNPB and the Acquisition of Food from Familiar Agriculture Program (PAA, in rural settlements in Jataí and Perolândia, in the Southwest area of Goiás.

    Full Text Available With the rapid development of Internet and Cloud computing, there are more and more network resources. Sharing, management and on-demand allocation of network resources are particularly important in Cloud computing. Platform as a Service (PaaS is one of the key services in Cloud computing. PaaS is very attractive for schools, research institutions and enterprises which need reducing IT costs, improving computing platform sharing and meeting license constraints. However, nearly all current available cloud computing platforms are either proprietary or their software infrastructure is invisible to the research community except for a few open-source platforms. For universities and research institutes, more open and testable experimental platforms are needed in a lab-level with PCs. In this paper, a framework for managing PaaS in a virtual Cloud computing lab is developed. The framework implements the user management, resource management and access management. The system has good expandability and can improve resources sharing and utilization.

    In rice,one detrimental factor influencing single panicle yield is the frequent occurrence of panicle apical abortion (PAA) under unfavorable climatic conditions.Until now,no detailed genetic information has been available to avoid PAA in rice breeding.Here,we show that the occurrence of PAA is associated with the accumulation of excess hydrogen peroxide.Quantitative trait loci (QTLs) mapping for PAA in an F2 population derived from the cross of L-05261 (PAA line) x IRAT129 (non-PAA variety) identified seven QTLs over a logarithm of the odd (LOD) threshold of 2.5,explaining approximately 50.1% of phenotypic variance for PAA in total.Five of the QTLs with an increased effect from L-05261,were designated as qPAA3-1,qPAA3-2,qPAA4,qPAA5 and qPAA8,and accounted for 6.8%,5.9%,4.2%,13.0% and 12.2%of phenotypic variance,respectively.We found that the PAA in the early heading plants was mainly controlled by qPAA8.Subsequently,using the sub-populations specific for qPAA8 based on markerassisted selection,we further narrowed qPAA8 to a 37.6-kb interval delimited by markers RM22475 and 8-In1 12.These results are beneficial for PAA gene clone.

    2005-07-01

    Hagavik is an organic farm (municipality of Malmoe in Sweden) and the grown crops at the farm are sugar-beet, wheat, tritricale and ley crop (for green manure). The farmer has erected a new farm scale biogas plant with a digester volume of 500 m{sup 3}. The motives for building the plant were to produce biogas for cogeneration and digestate for supplying the farm with nutrients. Biogas substrates, harvested at the farm, are ley crop and sugar-beet tops and external substrates are solid manure from horses and organic waste from industrial bakery. Digestion of fibre-rich substrates as ley crop and straw-rich solid manure at farm scale plants is fairly untested in Sweden. The fibre has a rather big impact on the rheological properties of the substrate mixture and digester slurry and can cause problems with pumping and ineffective stirring. To achieve satisfactory function on the pumps and stirrers the fibre-rich substrates the rheological properties has to be improved. This can be done by 1) mixing the fibre-rich substrates with rather large quantities of liquids which can result in low dry mater content both in substrates an digester slurry 2) reduce the fibre size by mechanical disintegration. The Swedish Inst. of Agricultural and Environmental Engineering (JTI) has been in charge of the evaluation of the biogas plant. Evaluation of the start-up phase of the plant, regarding the technical and biological function, was accomplished in July-November 2003. During year 2004 focus has been on practical experience running the plant. The plant electricity demand has been measured. Based on those measurements the calculated electricity demand running the plant with a biogas production at 600 m{sup 3}/d (3,54 MWh/d) corresponds to ca 2-3% of the energy content of the biogas. The calculated heat demand corresponds to 15 % of the biogas. At cogeneration (with assumed electrical efficiency of 34% and thermal efficiency of 55%) the net-energy production is 919 MWh/year where 44% will be electricity and the rest heat. Total investment for the plant is about 2,6 MSEK. The farmer has got a government investment subsidy of 0,6 MSEK. The price of the net-energy production has to be at least 0.40 SEK/kWh in order to balance the costs. This calculation includes the investment subsidy.

  2. Life cycle perspective on recycling of ashes; Livscykelperspektiv paa aatervinning av askor

    Energy Technology Data Exchange (ETDEWEB)

    Olsson, Susanna

    2007-07-01

    The purpose of this project was to, from a life cycle perspective, discuss the consequences of recycling or disposing combustion ashes. The aim was to regard regional as well as global environmental impacts and point at potential conflicts between different environmental objectives, in order to produce basic information for decision-making on criteria and regulations for ash handling.Three different ashes were studied: bottom ash from waste incineration, fly ash from combustion of peat and from forest fuels. For all ashes three different scenarios were studied, two where the ash is recycled, and one where it is disposed. Focus was put on the difference between the three scenarios during 100 years. The use of bottom ash from waste incineration for roads saved crushed rock and energy, but produced more leaching of metals than the disposal alternative. Using this ash in drainage strata saves sand but causes higher metal leaching too. The same conclusions can be drawn for fly ash from peat, here leaching of Arsenic is the main factor. Using the peat ash as road contraction material saves more resources than the use for drainage blankets. For forest fuel ash, both the use as road construction material and recycling to the forest saves resources and energy. Recycling to the forest saves most energy but also the resources of Zinc, Phosphorous and Dolomite. Leaching of metals is most important for the forest recycling, and the nature of this resource recycling can be argued. The results are most sensitive concerning transports and leaching, but also for maintenance of the constructions where the ash is used. For the forest fuel ash, the suppositions about the necessity of compensation for nutrients removed with the fuel, have important effects for the result. Generally it can be said, for all three cases, that the estimates of leaching of metals are very uncertain, and that there is a need to develop the existing models for long term leaching. The three cases demonstrated the importance of applying a life cycle perspective, since different types of environmental impacts dominated in different stages of the system's and construction's life cycle. While resource consumption, energy use and emissions to the atmosphere dominates at production and transport of materials, the emission to water dominates at the use of the functions. An environmental study focussing on the use of e.g. a road construction will then exclude large parts of the impacts

    2008-02-15

    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

    Anaphylaxis during anesthesia is uncommon. Diagnosis of peri-anesthesia anaphylaxis (PAA) requires anesthesia providers' vigilance for prompt diagnosis and treatment. In this case report, we present a challenging case with suspected PAA including its perioperative management, intensive care unit (ICU) course, and post-discharge follow-up. A 44-year-old female (body mass index = 26) presented for elective abdominal panniculectomy. Post-intubation, severe bronchospasm occurred that was non-responsive to nebulized albuterol and intravenous epinephrine. Continuous infusion of epinephrine was initiated. After aborting surgical procedure, the patient was transferred to ICU on continuous intravenous infusion of epinephrine. Venous blood sampling showed elevated troponin level. Echocardiography revealed ejection fraction of 25% suspicious of Takotsubo cardiomyopathy (mid cavitary variant). Tracheal extubation was only possible after three days. Subsequently, patient was discharged home with a cardiology follow-up appointment and a referral to an allergy specialist. Unfortunately at our institution (an academic university hospital in United States) along with neighboring institutions in near-by areas, the only allergy skin tests available are for local anesthetics and antibiotics, while neuromuscular blocking agents (NMBAs) cannot be tested (the suspected anaphylactic agent in our case was presumably rocuronium). In summary, PAA requires and responds to emergent diagnosis and immediate treatment; however there is still a long way to go to ensure post-PAA testing for inciting anesthesia-related allergens.

    This paper describes a general audio coding algorithm which has been recently standardized by AVS, China.The algorithm is based on a perceptual coding technique. The codec delivers near CD-quality audio at 128kb/s. This paper describes the coder structure in detail and discusses the reasons for specific design methods. A summary of the subjective test results are presented for the prototype codec. Comparison Mean Opinion Score (CMOS) test indicates that the quality of the AVS audio coder is comparable with MPEG Layer-3 audio coder. A real-time decoder was used for the characterization test,which is based on a 16-bit fixed-point DSP. The performance of the DSP solution was demonstrated, including computational complexity and storage characteristics.

    2012-07-01

    Biogas injection into the natural gas grid is a common practice in Sweden today. In order to condition the biogas to the quality matching the natural gas, propane (approx. 8 %) is injected in the biogas. This is a costly procedure which also introduces fossil components into a renewable gas flow. Because of this, it is desired to terminate the propane injection and inject biogas straight into the gas grid. This might affect certain customers and will affect billing procedures and this study has briefly examined the impact of injection of biogas in the gas grid without propane addition. The main findings are: 1. It seems technically possible to inject biogas without propane into the gas grid. Attention has to be paid to the quality requirements of certain sensitive customers, but most customers can accept the quality variations. 2. It is recommended that the minimum methane content of injected biogas is raised to 98 %. This might affect the operation and choice of upgrading equipment and will have to be evaluated from both a technical and an economical viewpoint in each case. 3. Downgrading the natural gas to biogas quality by air injection is not an option. 4. In order to make simplify billing procedures, the geographic location of biogas site injecting gas into the distribution network is crucial. The biogas site should be placed as close to the transmission network as possible. Further, two case studies concerning biogas injection into the transmission network are briefly discussed.

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.

    Surface modification of polyvinylchloride based heterogeneous cation exchange membrane was performed by graft polymerization of PAA and PAA-co-PANI/MWCNTs nanoparticles. The ion exchange membranes were prepared by solution casting technique. Spectra analysis confirmed graft polymerization clearly. SEM images illustrated that graft polymerization covers the membranes by simple gel network entanglement. The membrane water content was decreased by graft polymerization of PAA-co-PANI/MWCNTs nanoparticles on membrane surface. Membrane transport number and selectivity declined initially by PAA graft polymerization and then began to increase by utilizing of composite nanoparticles in modifier solution. The sodium and barium flux was improved sharply by PAA and PAAco- 0.01%wt PANI/MWCNTs graft polymerization on membrane surface and then decreased again by more increase of PANI/MWCNTs nanoparticles content ratio in modifier solution. The electrodialysis experiment results in laboratory scale showed higher dialytic rate in heavy metals removal for grafted-PAA and grafted-PAA-co-PANI/MWCNTs modified membrane compared to pristine one. Membrane areal electrical resistance was also decreased by introducing graft polymerization of PAA and PAA-co-PANI/MWCNTs NPs on membrane surface.

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

  15. Electrospinning of Bioactive Dex-PAA Hydrogel Fibers

    Science.gov (United States)

    Louie, Katherine Boyook

    In this work, a novel method is developed for making nano- and micro-fibrous hydrogels capable of preventing the rejection of implanted materials. This is achieved by either (1) mimicking the native cellular environment, to exert fine control over the cellular response or (2) acting as a protective barrier, to camouflage the foreign nature of a material and evade recognition by the immune system. Comprehensive characterization and in vitro studies described here provide a foundation for developing substrates for use in clinical applications. Hydrogel dextran and poly(acrylic acid) (PAA) fibers are formed via electrospinning, in sizes ranging from nanometers to microns in diameter. While "as-electrospun" fibers are continuous in length, sonication is used to fragment fibers into short fiber "bristles" and generate nano- and micro- fibrous surface coatings over a wide range of topographies. Dex-PAA fibrous surfaces are chemically modified, and then optimized and characterized for non-fouling and ECM-mimetic properties. The non-fouling nature of fibers is verified, and cell culture studies show differential responses dependent upon chemical, topographical and mechanical properties. Dex-PAA fibers are advantageously unique in that (1) a fine degree of control is possible over three significant parameters critical for modifying cellular response: topography, chemistry and mechanical properties, over a range emulating that of native cellular environments, (2) the innate nature of the material is non-fouling, providing an inert background for adding back specific bioactive functionality, and (3) the fibers can be applied as a surface coating or comprise the scaffold itself. This is the first reported work of dex-PAA hydrogel fibers formed via electrospinning and thermal cross-linking, and unique to this method, no toxic solvents or cross-linking agents are needed to create hydrogels or for surface attachment. This is also the first reported work of using sonication to

    In Sweden, about one million tones of wood ashes are produced annually, of which about 250,000-300,000 tones originate from biofuels, e.g. forest residues. Some of the ashes produced are deposited today. One alternative use is bringing back the ashes to the forest, recycling the mineral nutrients and base compounds. In bioashes, most essential mineral nutrients for plants are included, except for N, which is gasified at combustion. On most mineral soils in Sweden, plant available nitrogen is the nutrient limiting tree growth. On organic soils, tree growth is usually increased after addition of phosphorous and potassium. Thus, there is a potential for increased forest production on peatlands after ash fertilization. This can be a profitable measure. Nutrient compensation after harvesting involve ash addition with quite low doses. This is especially important in peatlands after whole-tree harvesting in order to prevent nutrient deficiency and reduced tree growth. However, there is a need for better knowledge concerning other environmental effects before ash addition can be put into large-scale practice. The general objective of this project is to study the effects of wood-ash addition on forest production and some other environmental variables on drained, forested peatlands. The studies concern tree growth, emissions of greenhouse gases and water chemistry (ground water and run off). An important issue addressed was if an expected increased accumulation of carbon (CO{sub 2}) due to increased tree growth can compensate for an expected increased emission of greenhouse gases (e.g. CO{sub 2} and CH{sub 4}) from the peat. In addition, the very effective greenhouse gas laughing gas (N{sub 2}O), must be taken into consideration. In 2003, two field experiments were established in the county of Smaaland in southeast Sweden, where wood ashes from biofuels were applied. One experiment was designed as a randomized block experiment (273 Anderstorp) where effects on forest production and greenhouse gases (CO{sub 2}, CH{sub 4}, N{sub 2}O) were studied. The other experiment (274 Bredaryd), 10 km away, was established in two drainage areas where emissions of greenhouse gases and water chemistry (ground water and run off) were studied. At the establishment of the experiments, the forests were dominated by Scots pine (Pinus sylvestris L.). In the end of the 1980's, the forest stands had been thinned and the soils drained at both experimental sites. Experiment 273 Anderstorp included five treatments: an untreated control, and, one low dose (3.3 tonnes DM/ha) and one high dose (6.6 tonnes DM/ha) of crushed ash and 'granulated' wood ash, respectively. It should be noted that the 'granulated' product was of a poor standard. In experiment 274 Bredaryd 3.1 tonnes DM/ha of crushed ash was applied. Two years after treatment in 273 Anderstorp no effects of the treatments on tree growth was detected, which could be expected considering the short effect period. There was a statistically significant effect of the addition of crushed ash on concentrations of potassium and boron in the Scots pine needles. For potassium there was an effect of the dose. The addition of wood ash did not change the CO{sub 2}-flux from the soil during the first 2.5 years of study. The annual emissions from the control plots were approximately 8,000 kg CO{sub 2}/ha during 2004 and 12,000 kg CO{sub 2}/ha during 2005. No significant effect of the treatments on the annual CH{sub 4}-flux was detected by analysis of variance, but there was a tendency for increased CH{sub 4}-emissions at the treated plots during late summer and autumn. The annual emissions on the control plots were approximately 3 kg CH{sub 4}/m{sup 2} during 2004 and 6 kg CH{sub 4}/m{sup 2} during 2005. N{sub 2}O-flux was only occasionally detected. In 2005, the mean CH{sub 4} emission of the ash fertilized plots was 60% higher (non significant) than the mean of the control plots. This corresponds to an increased emission of 90 kg CO{sub 2}/ha/yr to the atmosphere. To compensate for such an emission, accumulation of tree biomass needs to increase by approximately 2%. In run off, sampled in the main ditches, the electric conductivity increased after addition of 3.1 tonnes of crushed ash, as well as the concentrations of B, Br, Ca, Cd, Co, K, Cl, Li, Mg, Mn, Na, P, PO{sub 4}-P, S, SO{sub 4}-S and Zn. For most elements, the increase appeared immediately after the ash application, and lasted from a few months to the whole observation period (c. one year). The concentrations of Pb and V was lower than expected during six and nine months, respectively. Thereafter, the Pb-concentration tended to be higher than the control. The concentration of TOC was reduced during eight months, and pH was reduced during three months after the ash addition. The effects on ground water chemistry corresponded to the effects on chemistry in run off. Two months after treatment, the concentrations of B, Ca, Cd, Co, K, Cl{sup -}, Li, Mn, Na, P, S and SO{sub 4}-S were elevated in the groundwater in the ash treated area. For some of the elements this was evident down to 90-100 cm depth. The concentrations of As and TOC at 30-40 cm tended to be lower in the area treated with ash. The results from this study demonstrate the initial effects (1-2.5 years) of wood ash addition in some drained, oligotrophic peatland forests in southern Sweden. Ash addition may affect the turn over of the peat, and potentially affect other ecosystem properties, for several decades. Hence, in order to confirm the duration of the shown short-term effects, to establish the duration of not yet ceased effects, and, establish effects that might show up in a long-term perspective, continuous follow up of the established experiments is important. This long-term monitoring is also a prerequisite of a more complete evaluation of the benefits and possible detrimental effects on the environment of wood ash addition.

This is especially important in peatlands after whole-tree harvesting in order to prevent nutrient deficiency and reduced tree growth. However, there is a need for better knowledge concerning other environmental effects before ash addition can be put into large-scale practice. The general objective of this project is to study the effects of wood-ash addition on forest production and some other environmental variables on drained, forested peatlands. The studies concern tree growth, emissions of greenhouse gases and water chemistry (ground water and run off). An important issue addressed was if an expected increased accumulation of carbon (CO{sub 2}) due to increased tree growth can compensate for an expected increased emission of greenhouse gases (e.g. CO{sub 2} and CH{sub 4}) from the peat. In addition, the very effective greenhouse gas laughing gas (N2O), must be taken into consideration. In 2003, two field experiments were established in the county of Smaaland in south Sweden, where wood ashes from biofuels were applied. One experiment was designed as a randomized block experiment where effects on forest production and greenhouse gases (CO{sub 2}, CH{sub 4}, N{sub 2}O) were studied. The other experiment, 10 km away, was established in two drainage areas where emissions of greenhouse gases and water chemistry (ground water and run off) were studied. At the establishment of the experiments, the forests were dominated by Scots pine. In the end of the 1980's, the forest stands had been thinned and the soils drained at both experimental sites. The first experiment included five treatments: an untreated control, and, one low dose (3.3 tonnes DM/ha) and one high dose (6.6 tonnes DM/ha) of crushed ash and 'granulated' wood ash, respectively. It should be noted that the 'granulated' product was of a poor standard. In the second experiment 3.1 tonnes DM/ha of crushed ash was applied. Two years after treatment in no effects of the treatments on tree growth was detected, which could be expected considering the short effect period. There was a statistically significant effect of the addition of crushed ash on concentrations of potassium and boron in the Scots pine needles. For potassium there was an effect of the dose. The addition of wood ash did not change the CO{sub 2}-flux from the soil during the first 2.5 years of study. The annual emissions from the control plots were approximately 8,000 kg CO{sub 2}/ha during 2004 and 12,000 kg CO{sub 2}/ha during 2005. No significant effect of the treatments on the annual CH{sub 4}-flux was detected by analysis of variance, but there was a tendency for increased CH{sub 4}-emissions at the treated plots during late summer and autumn. The annual emissions on the control plots were approximately 3 kg CH{sub 4}/ha during 2004 and 6 kg CH{sub 4}/ha during 2005. N{sub 2}O-flux was only occasionally detected. In 2005, the mean CH{sub 4} emission of the ash fertilized plots was 60% higher (non significant) than the mean of the control plots. This corresponds to an increased emission of 90 kg CO{sub 2}/ha/yr to the atmosphere. To compensate for such an emission, accumulation of tree biomass needs to increase by approximately 2%. In run off, sampled in the main ditches, the electric conductivity increased after addition of 3.1 tonnes of crushed ash, as well as the concentrations of B, Br, Ca, Cd, Co, K, Cl, Li, Mg, Mn, Na, P, PO{sub 4}-P, S, SO{sub 4}-S and Zn. For most elements, the increase appeared immediately after the ash application, and lasted from a few months to the whole observation period (c. one year). The concentrations of Pb and V was lower than expected during six and nine months, respectively. Thereafter, the Pb-concentration tended to be higher than the control. The concentration of TOC was reduced during eight months, and pH was reduced during three months after the ash addition. The effects on ground water chemistry corresponded to the effects on chemistry in run off. Two months after treatment, the concentrations of B, Ca, Cd, Co, K, Cl{sup -}, Li, Mn, Na, P, S och SO{sub 4}{sup 2-}S were elevated in the groundwater in the ash treated area. For some of the elements this was evident down to 90 - 100 cm depth. The concentrations of As and TOC at 30 - 40 cm tended to be lower in the area treated with ash. The results from this study demonstrate the initial effects (1 - 2.5 years) of wood ash addition in some drained, oligotrophic peatland forests in southern Sweden. Ash addition may affect the turn over of the peat, and potentially affect other ecosystem properties, for several decades. Hence, in order to confirm the duration of the shown short-term effects, to establish the duration of not yet ceased effects, and, establish effects that might show up in a long-term perspective, continuous follow up of the established experiments is important. This long-term monitoring is also a prerequisite of a more complete evaluation of the benefits and possible detrimental effects on the environment of wood ash addition.

    An aqueous dispersion of poly (acrylic acid)-stabilised cerium oxide (CeO{sub 2}) nanoparticles (PAA-CeO{sub 2}) was evaluated for its stability in a range of freshwater ecotoxicity media (MHRW, TG 201 and M7), with and without natural organic matter (NOM). In a 15 day dispersion stability study, PAA-CeO{sub 2} did not undergo significant aggregation in any media type. Zeta potential varied between media types and was influenced by PAA-CeO{sub 2} concentration, but remained constant over 15 days. NOM had no influence on PAA-CeO{sub 2} aggregation or zeta potential. The ecotoxicity of the PAA-CeO{sub 2} dispersion was investigated in 72 h algal growth inhibition tests using the freshwater microalgae Pseudokirchneriella subcapitata. PAA-CeO{sub 2} EC{sub 50} values for growth inhibition (GI; 0.024 mg/L) were 2–3 orders of magnitude lower than pristine CeO{sub 2} EC{sub 50} values reported in the literature. The concentration of dissolved cerium (Ce{sup 3+}/Ce{sup 4+}) in PAA-CeO{sub 2} exposure suspensions was very low, ranging between 0.5 and 5.6 μg/L. Free PAA concentration in the exposure solutions (0.0096–0.0384 mg/L) was significantly lower than the EC{sub 10} growth inhibition (47.7 mg/L) value of pure PAA, indicating that free PAA did not contribute to the observed toxicity. Elemental analysis indicated that up to 38% of the total Cerium becomes directly associated with the algal cells during the 72 h exposure. TOF-SIMS analysis of algal cell wall compounds indicated three different modes of action, including a significant oxidative stress response to PAA-CeO{sub 2} exposure. In contrast to pristine CeO{sub 2} nanoparticles, which rapidly aggregate in standard ecotoxicity media, PAA-stabilised CeO{sub 2} nanoparticles remain dispersed and available to water column species. Interaction of PAA with cell wall components, which could be responsible for the observed biomarker alterations, could not be excluded. This study indicates that the increased

    Soil samples were taken in the forest fertilisation experiments Skogaby (SW Sweden), Asa (S Sweden), Straasan (C Sweden) and Flakaliden (N Sweden), all with replicated plots, to evaluate effects of intensive production of Norway spruce trees by repeated fertiliser application, on soil fauna diversity. The species-rich groups of Oribatida, Mesostigmata and Collembola were studied at all sites. Repeated additions of solid fertilisers mostly reduced the total number of individuals of soil fauna, whereas addition of liquid fertiliser did not result in any marked effects on totals densities. Forest fertilisation had small or insignificant effects on species numbers or diversity indices, but resulted in large changes in the composition of individual species. Generally, the most common oribatid species decreased in numbers, whereas less common species did not seem to decrease. Thus, intensive forest fertilisation did not seem to reduce the number of species but had a great effect on the community level by reducing some of the commonest species and favouring some sparsely occurring species. This indicates that forest fertilisation, if performed in a patchy manner, can increase the soil fauna diversity in the forest landscape as a whole.

    JTI has, on behalf of the Swedish Board of Agriculture, conducted a study on energy consumption in agriculture. The study also proposes measures to reduce the energy use and includes an outlook towards the future of the Swedish agricultural development. The study is limited to the use of fuel and electricity used for field-work and in farm work and energy for heating. Energy for heating of residential buildings and drying is not included in the mandate. The Swedish agricultural uses about 3.11 TWh of energy in the form of gas, electricity, oil and biofuels, not including drying and greenhouses. In addition, approx. 3.64 TWh of energy are consumed indirectly, 2.31 TWh of which from fertilizer use. The Swedish agriculture is moving towards fewer but larger farms. The number of enterprises has decreased from 26000 in year 2005 to 21700 in 2009. Increased energy production, both as a supplier of raw materials and recipients of products means that energy use is affected. In the future energy use will probably be affected by an increase in farm-based production of energy, primarily biogas for cogeneration. The variations in estimates of energy use are large, and agriculture's total energy use can vary between 1.64 TWh to 4.04 TWh, depending on the data sets used. Since the use of diesel dominate over the use of electricity, it is interesting to focus on reducing diesel consumption. Field work and harvest are the activities where the largest consumption of diesel is made. Measures can be taken are primarily farmers are running in a more energy efficient way. Other measures are: Reduced tillage; Replacing transport with tractor-trailer by truck; Transport of manure with other equipment than their own spreader; Livestock use of energy is primarily electricity for lighting, ventilation, distribution, cleaning, feeding, etc. The largest variations in energy use are associated with animal husbandry. It is difficult to generally comment on actions in order to reduce energy use in the farm. Care and maintenance of ventilation is a simple and effective measure that can reduce energy use by 10%. Smart technology choices, may, dependent on type of stable and local conditions, reduce the use of up to 60%. Well-designed and maintained lighting can save approximately 30%. The use of indirect energy is dominated by the production of fertilizers. It is approximately 2.7 TWh / year, but by using fertilizer manufactured with today's BAT, the indirect energy consumption be reduced to approximately 1.6 TWh/year

    Combustion of fuel in thermal power plants emits particles which creates coatings on the super heater tubes. The coatings isolate the tubes and impairs the efficiency of the heat transfer. Cleaning the tubes occurs while the power plant is running but without any knowledge of the actual coating. A change in frequency corresponds to a change in mass of the coatings. This thesis has been focusing in estimating resonance frequencies in vibration measurements made by strain gauges on the tubes. To improve the estimations a target tracking algorithm had been added. The results indicates that it is possible to estimate the resonance frequencies but the algorithms need to be verified on more signals.

    The conference paper deals with executed field tests on the adding of cadmium alone or combined with acidification of an enclosed space under different nutrient and predatory conditions. The addition of cadmium changed the biomass and the composition of the phytoplankton. In combination with the added nutrient salts, the biomass of special algae increased in the Cd loaded spaces, and the addition of acid changed the effect of Cd concentration by increased production of the same. The effect of a given Cd concentration on the zooplankton varied in a wide range of environmental conditions. 22 refs., 1 tab.

    The project evaluates the effects of slash harvest on plant diversity in forests. This is made through comparisons between conventionally clear-cut stands and clear-cut and slash harvested stands. Two different studies have been started. The first study consists of a direct comparison between the two types of clear-cut areas. The results show that the total species richness of vascular plants and bryophytes is not affected by slash removal. On the other hand, mosses and liverworts as a group become more species-poor. In the other study, bryophytes have been transplanted to shady and exposed parts, respectively, of clear-cut areas. Thereafter, half of the plots have been covered by slash and another half has been left exposed. The preliminary results show a considerably reduced vitality for the bryophytes living in the exposed parts of the clear-cut area without slash cover. The slash-covered bryophytes, on the other hand, performed well. On the shady part of the clear-cut area the bryophytes were similarly vital irrespective of slash cover or not. The conclusion is that slash removal can have a negative effect on plant diversity, especially if it is practiced on large exposed areas. If slash harvest is restricted to north-facing, shady, small clear-cut areas the effects could probably be eliminated.

    The overall aim of this study was to investigate how the use of ash in a long-term perspective affects the surrounding flora and fauna with regard to the accumulation of metals in the ecosystem through plant uptake and exposure to grazing animals. The study included a field study and a cultivation experiment. In the field study, the accumulation of metals and metalloids in leaves of trees and shrubs that had self established and grown in lysimeters with aged MSWI bottom ash and aged biofuel ash was determined. In the cultivation experiment, the accumulation of metals and metalloids from the studied materials in ryegrass was determined. Reference materials in the cultivation experiment were two conventional geotechnical materials, crushed rock and excavated soil. Leaves from trees and bushes in the vicinity of the ash lysimeters were used as reference materials in the field study. Contamination of plant samples with particles, through splashing during rain, dusting, or in connection with sampling, proved to have had a major impact on the measured metal and metalloid concentrations in several grass samples in the cultivation experiment. The results also indicate that contamination of plant samples with particles occurred in the field study. In this case, probably due to atmospheric deposition. The particle contamination complicated the evaluation of some of the results in the project since the intention was to study accumulation by roots from the studied ash materials, but, on the other hand, the particle contamination showed the importance of taking into account the spreading of contaminants through particles as an exposure route for grazing animals. In the field study, only Cd and Zn in aspen, willow and birch exhibited elevated levels in the leaves due to root uptake from MSWI bottom ash compared to the reference samples. In addition, elevated levels of As was observed in leaves from trees in the biofuel ash. The total content of As was similar in all studied ashes but the leachability was significantly higher in the biofuel ash. The measured concentrations in the leaves of ash lysimeters were below the tolerable daily intake (TDI) for cattle for all elements except Zn in willow, birch and aspen, where the levels were in the same range as TDI. However, the lower limit for TDI was exceeded for Zn also in some leaf samples from the reference areas. Thus, TDI for Zn seems rather low compared to concentrations that could normally occur in leaves from fast growing trees. Cultivation experiment showed that levels of Cu, Pb and Zn, and to some extent Cr and Cd, were clearly elevated in the ryegrass that grew in MSWI bottom ash. For Cu, Pb and to some extent Zn the concentrations exceeded the TDI for cattle. However, the measured concentrations were clearly affected by contamination of fine particulate MSWI bottom ash matter. This applied particularly to the grass samples from the pots with 100 % ash or reference material and not to those from with ash or reference material mixed with 50 wt % planting soil. In the grass growing in mixtures with 50 wt% MSWI bottom ash and 50 wt% plantation soil, the concentrations in the grasses were of the same magnitude as in the grasses from the reference materials, and below TDI for cattle

    This project includes three studies designed to investigate the effects of slash extraction on forest plant diversity. The first study explores the previously unknown effects of commercial slash harvest after clear-felling on bryophytes and vascular plants. Differences between conventionally harvested (i.e. slash left) and slash-harvested stands were investigated 5-10 years after clear-cutting through analysis of 28 paired stands. In each stand we studied vegetation patterns in 0.1 ha plots divided into five 0.02 ha subplots. Species composition of mosses and liverworts in 0.1 ha plots was significantly affected by slash harvest, whereas composition of vascular plant species showed no differences between conventional and slash harvested plots. Species richness of liverworts was significantly reduced by slash harvest in plots of both sizes (0.1 ha and 0.02 ha), whereas moss richness was reduced only in the smaller plot size. The loss of liverwort species was largest, with approximately one third of the species disappearing. The species richness of vascular plants was not significantly affected by slash harvest in either plot size. Slash harvest also reduced species richness of forest bryophytes and of bryophytes typically growing on organic substrates in open habitats. Species richness of non-forest bryophytes on inorganic substrates remained unchanged. The second study evaluates the effects of slash-cover on ground living bryophytes in seven different clear-cuts. By transplanting ten different species of bryophytes in manipulated plots located to north-facing forest edges and the centres of the clear-cuts) we evaluated the effects of branch cover and full exposure on bryophyte growth and vitality. In the more sheltered, north-facing plots there was no difference between treatments. In the centre of the clear-cuts, however, both growth and vitality of exposed bryophytes were significantly lowered in exposed compared to covered plots. The third study investigates the effects of stand structure and microclimate on species richness and resilience of wood inhabiting mosses and liverworts. We investigated differences between pairs of mature and recently clear-cut spruce stands located to north- and south-facing slopes, respectively. Bryophyte richness was highest in north-facing stands of both successional stages and in south-facing forests whereas south-facing clear-cuts presented the lowest species numbers. In north-facing slopes there was no difference in liverwort species number between mature and young stands. The mosses, however, presented higher species numbers in young stands. In south-facing slopes liverwort species numbers were significantly lower in young compared to mature stands whereas no difference was detected regarding mosses. Our study indicates that south-facing stands lose species, particularly among liverworts, after disturbance whereas no such loss seems to occur on north-facing slopes. North-facing slopes also appear to be more suitable for establishment of wood inhabiting bryophytes after disturbance. Differences between north- and south facing stands are most likely due to microclimatic differences, in particular available moisture influencing both species persistence and establishment. These studies indicate that commercial slash-harvest affects plant species composition and richness. Effects are most likely linked to loss of substrate and changes in microclimate. Leaving more tree clusters that offer shade and creating or protecting coarse woody debris may mitigate negative effects on particularly wood inhabiting and moisture dependent organisms. Commercial slash harvest should not take place in shaded and moist habitats where the effects of clear-cutting are less severe and where the conditions are suitable for persistence and establishment of wood-inhabiting species.

    The support from the Swedish government to the PV sector has so far mainly been focused on research and development. But in May 2005 this changed as the Swedish government introduced an investment support programme directed at grid connected PV systems on public buildings. During the autumn 2005 a Master Thesis was carried out at the department of Environmental Systems Analysis at Chalmers Univ. The purpose of the thesis was to study the effect of the support programme and make an early evaluation of its effects. Information has been gathered by following a number of new projects that have started as a result of the support programme. Interviews have been made with actors in these projects and also with other key actors in the Swedish PV sector. The Swedish translation of the thesis is much shorter and has a popular science character. It focuses on describing the studied projects and the experiences from them. The last part of the translation describes the effects of the investment support programme on the dynamics of the Swedish PV sector. The results of this report shows that the market deployment initiative has lead to the start of a number of new PV projects and grid connected PV systems on buildings is now responsible for the fastest growth also on the Swedish PV market. The support programme has on top of this created many other positive effects on the dynamics of the Swedish PV sector. It is too early to make statements about the occurrence of self-reinforcing mechanisms. But there are some important changes such as the creation of an industry association and that the regulatory framework is questioned. This indicates that these mechanisms can occur and blocking mechanisms be removed.

    Problems regarding that leachate from food waste have been corroding vehicles and concrete slabs has been reported by Biogas- and composting plants. This is an issue that has been reported to Swedish Waste Management more often within the same pace as the volume of food waste gathering is increasing all around Sweden. The problem has also been addressed at inspections according to SPCR 120 Biogoedsel and SPCR 152 Kompost, where several plants have requested guidance/support/investigation to help solve their specific issue. Swedish Cement and Concrete Research Inst., has earlier completed some investigations which have been ordered by private plant owners/municipalities and the result from these investigations have often proved that the exposure classification has not been adjusted for its purpose. There is no clear definition regarding construction of concrete that is meant for usage in a receiving hall for food waste. It is likely that concrete for Biogas- and Composting plants are built to meet the demands of agricultural environments. The project will examine the magnitude of the problem regarding corrosion- and weathering damage on concrete slabs and cisterns at biological treatment plants. The project will also culminate to actual solutions for plants that are hit and to give advice to those in the danger zone and those who plan for new constructions. Through a survey handed to Biogas- and composting plants around the country, the width of the problem has been examined and what solutions plants have found and executed to solve this issue. A literature review has been implemented to find specific demands regarding concrete that is meant for a certain environment. Another four treatment plants have been examined. The studies that have been made are chemical analysis of leachate from food waste, analysis of drill cores and analysis of reinforcement corrosion. The results from this project show that concrete doesn't have enough resistance in these environments where food waste is treated. No matter which quality of concrete is put in use these problems will occur, though in different speeds. To ensure the function of the concrete construction, the concrete must be protected with a sealing coat. These sealing coats must be able to endure the aggressive nature from leachate coming from food waste and be resistant to mechanical abrasion from vehicles. In the report several seal coatings are shown that have been used for solving measures. Some of these have worked, while others didn't work as well. To be able to ensure the function within the different seal coatings they have to be tested in 'their proper' environment considering the chemical temperature and composition of the leachate. There are no standard methods to perform this, they have to be developed. There are plans for a new study where you bring out specific demands and standard methods for seal coats in food waste environments. Corrosion problems also occur on gathering vehicles for food waste and mechanic equipment at treatment plants, it is desired also to deal with these issues and a study is recommended regarding the influence from food waste on metal materials that are in contact with food waste

    In plantations of willow, the size- and weight variability of established plants is increasing over time. This size-hierarchy development is enforced by competition for resources between plants, and is preserved by root reserves and maintained over harvest. This long-term development causes mortality of entire willow plants, and thereby to gaps in the stand, and production losses under later cutting cycles. Variations in productivity across a field may be caused by soil fertility- and moisture gradients and by differences in weed pressure. Even difference between adjacent plants during the establishment phase may be caused by small scale differences in the biotic (weeds) and abiotic (moisture, nutrients) direct environment of the plants. But the central question here is whether differences between single cuttings may contribute to the development of a size- and weight hierarchy between willow plants during the early establishment phase? And if so, (i) to what degree do differences between cuttings contribute to the development of a hierarchy and (ii) are we able, in commercial practice, to modify cutting handling and selection to minimise the development of early size variations between plants? This research project aimed to quantify how cutting length and -origin and cutting handling during planting affects survival and growth of plants in a willow stand under establishment. The goal was to identify and quantify cutting characteristics which are of relevance for a high viability and for a fast and equal establishment of a willow stand, and thereby to be able to recommend advice which leads to a faster and more reliable establishment of willows. The study was performed by means of two box experiments under controlled conditions and by means of a field experiment during May 2008 - September 2009, on the Ultuna campus (SLU) nearby Uppsala. In all trials, the clones Tora (Salix schwerinii x S. viminalis), Jorr (Salix viminalis), Olof (Salix viminalis x (Salix schwerinii x Salix viminalis)), Sven (Salix viminalis x (Salix schwerinii x Salix viminalis)) and Gudrun (Salix dasyclados) were used. In the box experiment 2008, we studied how cutting characteristics (clone, cutting length, weight and basal diameter, the original position of the cutting on the long shoot, and storage time under field conditions after long-term cold storage) affected survival, sprouting of shoots (emergence time, number of shoots, height growth rate) and shoot size (weight and leaf area development). In the box experiment 2009, we investigated how cutting characteristics and planting conditions, which led to different degrees of damage of the cuttings, affected survival, sprouting and consecutive growth. In the field experiment 2008-2009, we studied how cutting characteristics, in combination with a natural variation in soil conditions, weed pressure and competition from adjacent willows (planted in pure stands and in clonal mixtures) affected sprouting and survival during two seasons. This study showed that the investigated cutting characteristics, including choice of clone, have a profound influence on early establishment and thereby on the competitive ability against weeds. The size (length and diameter) of the cutting determines to a large degree how fast a plant can grow during early establishment. The phenological development rate (rate of bud burst and unfolding) largely depends on the cuttings origin along a long shoot (close to the base or to the top of a long shoot), and cuttings from a basal origin display a later bud burst. Even if large-sized cuttings (from an origin close to a long shoot base) tend to have a later bud burst than cuttings from an apical origin, cutting size is the major determinant for the size of a plant after about six weeks. Storage at field edge may result in bud burst on long shoots prior to planting, and in general those buds die at planting, resulting in burst of secondary buds. This process causes a delay in establishment and results in an increase in the relative size variation within an establishing stand. Planting in compacted soil results in an increased damage frequency in cuttings, and especially thinner cuttings will be damaged. These obtain a poor soil contact and are liable to desiccation. Consequently, we recommend use of relatively long and thick cutting material for the establishment of a willow stand. Storage time of cuttings under field conditions should be minimised, especially at higher temperatures. Particularly during planting in compacted soils and with thinner cuttings, growth and development will be slow, leading to poor establishment and thereby to less productive willow stands

    Grepperud, Sverre; Rasmussen, Ingeborg

    1998-07-01

    The purpose of this report is to evaluate possible long run effects on use of energy and CO2-emissions from improved energy efficiency in various production sectors and for some consumption goods. The results suggest that improved energy efficiency decrease energy consumption, but the initial reduction is modified over time due to Rebound effects which arises from changes in income and prices. Wide differences in changed energy use are observed across the sectors evaluated. The report also include an analysis of possible effects from installing new environmental technology or clean up technology at firm level. The consequences of such new technologies are found to depend on the type of technology implemented, but also on the type of environmental regulation a firm is subjected to. (author)

    2007-01-01

    The colloidal crystal template or opal with a closed-packed face-centered cubic (fcc) lattice was prepared from monodisperse polystyrene (PS) spheres by vertical sedimentation. The template provided void space for infiltration of monomer precursor composed of acrylate acid, acrylamide and ammonium persulfate, as well as microgel from the subsequent copolymerization. The sample was immersed in dimethylbenzene for completely removing PS spheres to form PAM inverse opal hydrogels (IOHPAM) or PAM/PAA inverse opal hydrogels (IOHPAM/PAA) photonic crystals. The PS spheres were replaced by air spheres, which interconnected each other through the windows. The study of responses to pH show that there are two peaks for both IOHPAM and IOHPAM/PAA films, but the IOHPAM/PAA peaks shift to higher pH, and the peaks are independent with the AA content.

    2007-01-01

    Carbon fibres (CF) were modified with different oligomeric silsesquioxane (SSO) coatings to improve the interfacial property of carbon fibres/polyarylacetylene (CF/PAA).The interlaminar shear strength (ILSS) of CF/PAA was tested to determine the effect of the treatment.Atomic force microscopy (AFM) in force modulation mode was adopted to study the cross-section surface of unidirectional CF/PAA composites and the relative stiffness of various phases, including CF,interphase and resin.The probability histogram and line distribution of CF/PAA cross-section surface relative stiffness,obtained from the statistical analysis of relative stiffness image,were used to compare and study the interface characterizations of composites.The results show that the ILSS increases effectively and the effects on interfacial characterizations are distinguished from each other in accor-dance with the CF surface modified with different SSO coatings owing to the various structures.Cage oligomeric silsesquioxane,including large organic groups (methacryl isobutyl-POSS),has better treatment result.AFM observa-tions lead to the conclusion that an interfacial transition layer with different morphology and stiffness appears in CF/PAA composites after being treated by the SSO coatings of different structures.It can be inferred that the appearance of the transition layer may contribute to the improvement of fibre/matrix adhesion.

    Full Text Available Hexagonal nanoarrays of Au nanorods and nanopillar were deposited on nanoporous anodic alumina (PAA membranes utilizing dc electrodeposition. The surface morphologies and optical properties were characterized by using field emission-scanning electron microscopy (FE-SEM and UV-Vis spectrophotometer, respectively. The optical reflectance spectra of the as-prepared, pore widened, and 2D-Au nanorods-coated PAA membranes were studied in detail. The effects of the angle of incident, pore widening time, and electrodeposition time on the characteristic peaks positions and intensities of the fabricated nanoarrays were addressed. As the angle of incident increased, the interference peaks and transverse surface resonance are shifted to longer wavelengths, but the longitudinal surface plasmon resonance is shifted to shorter wavelengths. Also, the reflected intensities are decreased linearly for the as-prepared sample and decreased exponentially for Au/PAA samples. Using the modified Kubelka-Munk radiative transfer model, the energy gap is increased from 2.83 to 3.06 eV and the refractive index is decreased from 1.84 to 1.36 for the as-prepared and 70 min pore widened PAA membranes, respectively. Based on the advantages of the fabrication approach and the enhanced and controlled properties, this generation of Au/PAA arrays can be used as efficient building blocks for nanoelectronics and nanophotonic devices.

    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%.

    Mining industry produces 25 Mton mine tailings yearly that are deposited in impoundments in the nature. When this sand, containing sulphur rich minerals, reacts with oxygen and water it starts to weather and acidic metal rich water is formed. To prevent this, the sand can be covered with a sealing layer and a protective cover layer with vegetation. As sealing and cover materials fly ashes and sewage sludge can be used. The aim of this investigation was to find out: 1) how sealing layer of fly ashes with and without sewage sludge, and a cover with sewage sludge can be placed practically on mine tailings in a cold climate. 2) how such a cover should be constructed to minimize the risk of root penetration and leakage of nutrients and metals 3) which vegetation that is most suitable This was investigated in field- and greenhouse tests with a sealing layer of fly ash and/or sewage sludge with a cover layer of sewage sludge in which different plant species were established. The practical application was performed in 0.3-1 ha plots at a mine tailings impoundments at Boliden. The ability of plant roots to penetrate a sealing layer was investigated, as well as the effect of simulated root exudates on the penetration resistance in hardened ash. Leakage of nutrients and metals from cover layer of sewage sludge, in some cases with sealing layers beneath, was investigated in field and greenhouse lysimeters. Various plant species were compared on their ability to affect metal and nutrient leakage as well as root penetration and shattering of the hardened ashes. The project was a cooperation between Stockholm University and Boliden Mineral AB, and the field tests were performed at the impoundment Gillervattnet in Boliden and in Garpenberg. Cooperating were also Iggesund Paperboard, Skellefteaa Kraft, Stora Enso Fors, Umeaa Energi and Vattenfall, all producers of ashes that were used, as well as Stockholm Vatten AB, which produced the sewage sludge. The most important conclusions are that: It is possible to apply a sealing layer of ashes on mine tailings independent of season due to the quick hardening process of the ashes. Sewage sludge can, on the other hand, only be applied when the tailings are frozen. The application leads to a rise in the ground water level in the tailings Covering of mine tailings with sewage sludge and fly ash decreases the metal leakage. The higher proportion of sewage sludge in the cover layer the more N and P and less metals is released. The leakage decreases with time. Plant establishment in general decreases the leakage of metals and nutrients, especially by decreasing the amount of leakage water. Because of great amounts of nitrate in sewage sludge plants with a high uptake of nitrate is to prefer to decrease the nitrogen leakage. Some plant species can loosen up the surface of hardened fly ash, and in that way influence the sealing layer structure. This may lead to increased breaking down of secondary minerals, which can be important for the stability of the sealing layer. It is possible that excretion of sacharids from plant roots can increase shattering of ash, and that such exudation increases in the presence of ash. Estimation of the resistance needed to avoid root penetration were made to approx2,5 MPa. Addition of sewage sludge increases the risk of root penetration of a sealing layer. Since roots can affect a thin sealing layer a thickness of approximately 0.5 meter is recommended

    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.

    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

    A new route to porous polyimide(PI)films with pore sizes in the nanometer regime was developed.A polyamic acid(PAA)/polyurethane(PU)blend with PU as the disperse phase was first prepared via in situ polymerization of pyromellitic dianhydride and 4,4-oxydianiline in PU solutions.Porous PI films were obtained from PAAJPU films by thermolysis of PU at 360℃ and imidization of PAA at 300℃,respectively.Fourier transform infrared spectroscopy and thermal gravimetric analysis were used to detect the imidization and thermolysis processes of PAA/PU blends under thermal treatment.The microporous structure of the PI films was observed by transmission electron microscopy.It was found that the size and content of pores increased with an increase in the PU mass fraction in the PAA/PU blend up to 20%.Because of the existence of nanopores,the dielectric constant of PI films decreased by a wide margin and was less than 2.0 at a PU mass fraction of 20%.It implies that this is an effective means to reduce the dielectric constant of PI,but it also causes the decrease of tensile strength and the rise of water absorption.

    In this study we combined experimentation with mathematical modeling to unravel the in vivo kinetic properties of the enzymes and transporters of the penicillin biosynthesis pathway in a high yielding Penicillium chrysogenum strain. The experiment consisted of a step response experiment with the side chain precursor phenyl acetic acid (PAA) in a glucose-limited chemostat. The metabolite data showed that in the absence of PAA all penicillin pathway enzymes were expressed, leading to the production of a significant amount of 6-aminopenicillanic acid (6APA) as end product. After the stepwise perturbation with PAA, the pathway produced PenG within seconds. From the extra- and intracellular metabolite measurements, hypotheses for the secretion mechanisms of penicillin pathway metabolites were derived. A dynamic model of the penicillin biosynthesis pathway was then constructed that included the formation and transport over the cytoplasmic membrane of pathway intermediates, PAA and the product penicillin-G (PenG). The model parameters and changes in the enzyme levels of the penicillin biosynthesis pathway under in vivo conditions were simultaneously estimated using experimental data obtained at three different timescales (seconds, minutes, hours). The model was applied to determine changes in the penicillin pathway enzymes in time, calculate fluxes and analyze the flux control of the pathway. This led to a reassessment of the in vivo behavior of the pathway enzymes and in particular Acyl-CoA:Isopenicillin N Acyltransferase (AT).

  11. Lability of the pAA Virulence Plasmid in Escherichia coli O104:H4: Implications for Virulence in Humans.

    Directory of Open Access Journals (Sweden)

    Wenlan Zhang

    Full Text Available Escherichia coli O104:H4 that caused the large German outbreak in 2011 is a highly virulent hybrid of enterohemorrhagic (EHEC and enteroaggregative (EAEC E. coli. The strain displays "stacked-brick" aggregative adherence to human intestinal epithelial cells mediated by aggregative adherence fimbriae I (AAF/I encoded on the pAA plasmid. The AAF/I-mediated augmented intestinal adherence might facilitate systemic absorption of Shiga toxin, the major virulence factor of EHEC, presumably enhancing virulence of the outbreak strain. However, the stability of pAA in the outbreak strain is unknown. We therefore tested outbreak isolates for pAA, monitored pAA loss during infection, and determined the impact of pAA loss on adherence and clinical outcome of infection.E. coli O104:H4 outbreak isolates from 170 patients (128 with hemolytic uremic syndrome [HUS] and 42 with diarrhea without HUS were tested for pAA using polymerase chain reaction and plasmid profiling. pAA-harboring bacteria in stool samples were quantified using colony blot hybridization, and adherence to HCT-8 cells was determined. Isolates from 12 (7.1% patients lacked pAA. Analyses of sequential stool samples demonstrated that the percentages of pAA-positive populations in the initial stools were significantly higher than those in the follow-up stools collected two to eight days later in disease (P≤0.01. This indicates a rapid loss of pAA during infections of humans. The pAA loss was associated with loss of the aggregative adherence phenotype and significantly reduced correlation with HUS (P  = 0.001.The pAA plasmid can be lost by E. coli O104:H4 outbreak strain in the human gut in the course of disease. pAA loss might attenuate virulence and diminish the ability to cause HUS. The pAA instability has clinical, diagnostic, epidemiologic, and evolutionary implications.

    There are a number of Swedish test roads and test areas with processed municipal solid waste incinerator bottom ash, here called MSWI gravel. It is used in different road layers and for different purposes. Many of these have been monitored through falling weight deflectometer (FWD) measurements. The main purpose of this project is to increase the knowledge of the long-term strength of MSWI gravel, when it is used as a road material. Another purpose is to take advantage of the existing test roads. FWD measurements have been performed on two of the existing test roads with MSWI gravel in the sub-base. One road was constructed in 2001 and is situated in Umeaa, close to the Daava power station of Umeaa Energi. The other test road was constructed in 1998 in Toerringe, outside Malmoe. In both cases a test structure as well as a reference structure has been measured. Both test roads have been measured before and the data from this project have been evaluated in the same way as earlier (layer moduli for different layers and surface modulus for the whole road structure respectively). The result is presented and compared with the earlier data. The values obtained for the MSWI gravel have also been related to the corresponding values for the crushed rock material in the reference structures. The result shows that in Toerringe, the stiffness of the MSWI gravel has not changed compared with the results from earlier measurements. However, in Daava the stiffness of the test structure was lower in 2004 than in 2002. In both test roads, the test structure had lower stiffness than the reference structure. In Toerringe, the ratio between the stiffness of the test structure and the stiffness of the reference structure was unchanged. In Daava, however, the stiffness ratio had increased. The stiffness increase that has been observed on an older test road in Linkoeping has not been observed on these roads with MSWI gravel of more 'modern' type. It is maybe due to the longer storage time before use, for modern bottom ash. This project is the only long-term monitoring of this type in Sweden and therefore the result is unique. The experiences could be used when planning new similar objects. It is then important with homogenous subgrade conditions, a reference structure (of course), careful documentation of the construction and a monitoring period that is longer than two-three years. It is recommended to continue the monitoring of the two test roads with FWD measurements in 2006. The object is to see whether the trend in Toerringe continues and to see what the trend in Daava is. It is also recommended to monitor the water content in the two roads, in order to explain the results better. This study, as well as earlier laboratory and field studies, shows that MSWI gravel is less stiff than crushed rock with larger particle size. Today, the stiffness is used as input in the design manual of The Swedish National Road Administration (SNRA). Bearing capacity is another measure of strength that could be used. Bearing capacity is the resistance to permanent deformation/settlements during loading. Laboratory tests have shown that MSWI gravel has better bearing capacity than natural gravel with the same particle size. SNRA and SGI are working to include the bearing capacity in the future design manual.

    Wood ash can be used for forest fertilization on peatlands or for nutrient compensation following intensive harvesting. This project was performed in order to investigate effects on water chemistry of applying wood ash to a Scots pine stand on a drained peatland. Ditch-water chemistry was monitored before and after the application of wood ash. Furthermore, groundwater was collected and chemically analyzed both from the ash-treated peatland and from an adjacent untreated reference peatland. Both short term (a few months) and more long term effects (up to three years after application) were detected on water chemistry

    2007-07-01

    Full Text Available Electrical conduction characteristics in two different polyimide films prepared by the imidization of polyamic acid (PAA and pre-imidized polyimide (PI solution were investigated. It is found that the current density of the polyimide film from PAA was higher than that of the polyimide film from PI at the same electric field, even though the conduction mechanism in both polyimide films follows the ionic hopping model. The hopping distance was calculated to be 2.8 nm for PAA type and 3.2 nm for PI type polyimide film. It is also found that the decay rate of the residual electrostatic charges on the polyimide films becomes faster in the PAA type than in the PI type polyimide film.

    Cross-linked poly(vinyl alcohol) (PVA)/poly(acrylic acid) (PAA)/silica hybrid membranes were prepared to evaluate the possibility of use as a proton exchange membrane for direct methanol fuel cell (DMFC). A chemical cross-linking agent having sulfonic acid group (-SO{sub 3}H) was used to increase proton conductivity, and simultaneously to prevent methanol transport through the cross-linked membranes. In addition, silica particles were dispersed into polymer matrices via sol-gel reaction under acidic conditions, expecting the barrier to the methanol transport. The proton and the methanol transport were investigated in terms of PVA/PAA compositions and cross-linker (sulfosuccinic acid, SSA) concentration. It was found that the compositions of PVA/PAA and the cross-linker concentration affected the transport properties of the membranes. Particularly, the concentration of cross-linker markedly affected the proton and the methanol transport because SSA was used not only as a chemical cross-linker but also as a donor of fixed anionic group (-SO{sub 3}{sup -}H{sup +}). The proton conductivities of the hybrid membrane were in the range of 10{sup -3}-10{sup -2} S/cm, and the methanol permeabilities ranged between 10{sup -8} and 10{sup -7} cm{sup 2}/s. Noticeably, the methanol permeabilities were reduced by cross-linking between PVA, PAA and SSA chains without a large sacrifice of proton conductivity. Moreover, the silica particles embedded in the cross-linked polymer membranes acted as a reducing material for fraction of free water as well as a methanol barrier to hinder pathway from penetrating methanol molecules.

    In this paper, an antifouling hydrogel coating of slippery hydrogel-released hydrous surface (SHRHS) with the self-cleaning ability of oil-resistance and self-regeneration characters was designed. A physical blending method of loading Sodium polyacrylate (PAAS) powder into the organic silicon resin was employed to prepare the SHRHS coating. The oil-resistance of the intact and scratch SHRHS coatings was performed by time-sequence images of washing dyed beef tallow stain away. The results showed that the SHRHS coating has the greater ability of stain removal. The concentration of Na+ ions released from PAAS hydrogel on the surface of the SHRHS coating was investigated by ion chromatograph (IC). The results revealed that the coating had the ability of self-regeneration by PAAS hydrogel continuously peeling. The biomass of two marine microalgae species, Nitzschia closterium f. minutissima and Navicula climacospheniae Booth attached on the SHRHS was investigated using UV-Visible Spectrophotometer (UV) and Scanning electron microscopy (SEM). The results showed that the microalgaes attached a significantly lower numbers on the SHRHS in comparison with the organic silicon coating. In order to confirm the antifouling ability of the SHRHS coating, the field trials were carried out for 12weeks. It showed that the SHRHS may provide an effective attachment resistance to reduce biofouling. PMID:24594048

    Formation of mineral scales on heat exchangers is a persistent and expensive problem. In the presentpaper, the calcium carbonate scale inhibition by two inhibitors, polyacrylic acid (PAA) and 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) has been studied in a pool boiling system. It is found that PBTCA has abetter inhibition effect than PAA under the identical conditions. X-ray diffraction(XRD) and Fourier transform-infrared(FTIR) analyses demonstrate that the content of vaterite increases as inhibition effects increase. Themetastable crystal forms of vaterite and aragonite are stabilized kinetically in the presence of inhibitors. Therelationship between the inhibition effect and the fractal dimension has also been investigated. The result showsthat the fractal dimension is higher in the presence of inhibitors. The better the inhibition effect, the higher thefractal dimension. The step morphology was observed by atomic force microscopy (AFM) images. It is shown thatthe step space on the calcium carbonate surface increases in the presence of inhibitors. Moreover, with the increaseof inhibition effect, both the step space and the fractal dimension increase. The step bunching is found on thecalcium carbonate by AFM. The better the inhibition effect of the inhibitor, the slower the step velocity in theunbunched location. As a result, the step space becomes wider in the presence of PBTCA than that in the presenceof PAA.

  4. Arvelig hemokromatose - nytten av screening

    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.

    Full Text Available Målet med artikkelen er å synliggjøre hvordan bachelorstudenter i ergoterapi kan utvikle profesjonell handlingskompetanse gjennom aktivitetsbasert pedagogikk. På bakgrunn av dette gjennomførte vi kvalitative fokusgruppeintervju med 12 ergoterapeutstudenter som hadde deltatt i undervisningsopplegget “Aktivitetsgrupper-lede og delta”. Datamaterialet ble analysert etter retningslinjer for fenomenologisk basert meningskondensering. Studentene diskuterte sine erfaringer og det kom tydelig fram at undervisningsopplegget ga dem muligheter til å bruke sitt engasjement og sin kreativitet i valg av aktiviteter for sin simulerte aktivitetsgruppe. Videre fikk de muligheter til å oppdage sider ved anvendelse av aktiviteter for ulike pasienter, som de ikke kunne forstå uten integrering av teori i praktisk ferdighetstrening. Ved planlegging, gjennomføring og refleksjon over å lede og delta i aktivitetsgrupper, oppøvet de evnen til handlingsrefleksjon. Aktivitetsbasert pedagogikk kan bidra til utvikling av profesjonell handlingskompetanse og det er behov for både teoretiske og praktiske læringsformer. Funnene ble diskutert i lys av pedagogisk handlingsteori.

    MnFe2O4 nanoparticles and polyacrylic acid PAA/MnFe2O4 nanocomposites were synthesized by a hydrothermal method and ultrasonic mixing process. The obtained materials were characterized by XRD, FTIR, SEM, TEM, and VSM. XRD patterns indicate that the synthesized MnFe2O4 nanoparticles have a single cubic spinel phase. SEM images confirm the existence of three types of basic morphology of MnFe2O4 nanoparticles: octahedral, flower-like, and plate-like particles. High saturation magnetization Ms (up to 74.6 emu/g) of the as-synthesized MnFe2O4 nanoparticles was obtained. Experiments demonstrate that the variation of the hydrothermal reaction time does not remarkably affect the magnetic properties of MnFe2O4 nanoparticles. In PAA/MnFe2O4 nanocomposites, the coating of PAA leads to a slight decrease in magnetization of MnFe2O4 nanoparticles. Additionally, PAA coating greatly enhances the adsorption properties of MnFe2O4 nanoparticles for Methylene Blue (MB) dye. Especially, the removal efficiency reaches 96.3%. This research indicates that the as-synthesized PAA/MnFe2O4 nanocomposites exhibit excellent magnetic properties and can be taken as a promising adsorbent for removal of MB dye in industrial scale.

    The solutions of poly(acrylic acid)(PAA), poly(acrylic acid sodium)(PAANa) were coated on aluminium fins by roll coating method. The coatings with different crystallinity were obtained by varying baking time and temperature. Their surface crystallinity and surface tension were measured, and their spreading speed constant and equilibrium contact angle were tested also. The correlation of surface crystallinity, surface tension, spreading speed constant and surface hydrophilicity was discussed. It is demonstrated that surface tension and spreading speed constant increase, while equilibrium contact angle declines with increasing surface crystallinity of coatings, that is to say, the hydrophilicity of coatings is improved with surface crystallinity of coatings increasing.

    According to the Environmental Court's decision Gabriel Mountain the wind plant's impact on reindeer husbandry followed up by a control program. According to the Environmental Court's decision Gabrielsberget the wind plant's impact on reindeer husbandry followed up by a control program. The control program was initiated in autumn 2008. Reporting to the County Board will be made annually until the trial period ends. The construction of roads on Gabriel Mountains began in November / December 2008. No construction work was carried out, however, during the period that the reindeer were in the area (January-March 2009). The construction work started again in the summer / fall of 2009. The first 20 wind turbines began operating in January 2011. During these periods, the continuous interviews were held with reindeer herders from grazing district Byrkije. Reindeer herding utilization of the area before the wind farm been built and under construction has thus been mapped. Despite good grazing conditions Byrkije experienced difficulty in reindeer herding in and around wind power construction at Gabriel Mountain, especially during the second winter season (2010/11), when construction has been more extensive. Byrkije had to support feeding and use helicopter, something that previous seasons only was done in poor grazing conditions. The herders were also more people who worked actively with the reindeer and the working day has been longer and more strenuous compared to the seasons before the wind farm was built. The reindeer has moved more and were more spread out. The herders have also been forced to retrieve outside reindeer winter Loegdeaa land, something that has rarely happened in previous seasons. The reindeer's movement patterns and utilization of pastures have been different during the construction of the wind farm than in previous years. This report will be based on the new data over the years monitoring program runs.

  11. Imports of waste fuels for energy recovery in Sweden - Sub-Project 1; Import av avfall till energiutvinning i Sverige - Delprojekt 1 inom projektet Perspektiv paa framtida avfallsbehandling

    Swedish imports of waste fuels may increase to 1.5 million tonnes by 2015, when new waste-fuelled combined heat and power plants are in operation; and to 2.5 million tonnes by 2020, if all planned capacity is built. This is the case if national targets for increased material recycling and biological treatment are reached; which means that smaller amounts of mixed waste remains for incineration. When the import of the waste fuel into Sweden has increased, also need of knowledge has increased, as well as the concerns and fears. The aim of the project 'Imports of waste to energy recovery in Sweden', therefore, is to create an improved basis for decisions and communications concerning the import of waste fuel, as well as to study its conditions, opportunities and obstacles. The target group is interested operators, representatives of public authorities and decision-makers. Data includes analysis of future imported quantities, possible import markets, policy instruments and its effects, concerns and fears, economic aspects and effects on climate change while importing the waste fuel. The project is one of five sub-projects in 'Perspectives on the future waste treatment'. The project has been carried out through data collection, computer modelling, interviews as well as discussion and analysis in the working and reference groups. The goal is estimated to having been reached, the results are already used. From media, there is an interest of the results, and the project has already been referred to and presented at conferences. The results are thus already well-spread.

    There are several recently introduced and future possible policy instruments that are of great interest to study in order to understand the future for the Swedish waste treatment market. In the energy sector, the use of system analysis models has proven to be effective in order to understand the effects and consequences of policy instruments. In the waste sector, however, such analyses have only been conducted sporadically. This in spite of the introduction of highly influential policy instruments such as producer responsibility, landfill tax and landfill ban, which together have contributed to landfilling of Swedish household waste practically has ceased. The goal of this project was, by using system analysis models, to study and evaluate the newly introduced and future possible policy instruments which affect Swedish waste treatment. The assessment was made in terms of how policy instruments affect: - the distribution of treatment technologies, - waste amounts, - greenhouse gas emissions and - the economics of waste treatment. The project was performed during 2011 and 2012 as a part of the research project 'Perspectives on sustainable waste treatment (PFA)'. During the project, discussions have taken place within the working group and the reference group on which instruments are most interesting and relevant to study. Furthermore, opinions have been gathered from the association Swedish Waste Managements policy instrument group and from various players in the industry at conferences, presentations and workshops.

  13. Marine wind farms and seabirds. Updated national screening of potential conflict areas; Offshore vindenergianlegg og sjoefugl. Oppdatert screening av potensielle konfliktomraader paa nasjonal skala

    Christensen-Dalsgaard, Signe; Lorentsen, Svein-Haakon; Hanssen, Frank; Systad, Geir Helge

    2011-07-01

    In 2010 NINA performed a screening of areas that may be suitable for the establishment of offshore wind power plants (Christensen-Dalsgaard et al. 2010). The surveyed area ranged from the Swedish border in the south (North Sea/Skagerrak) to the northern tip of Andoeya (Norwegian Sea). Following the publishing of the report the Directorate for Nature management wanted to extend the analysis so that it also covered the Barents Sea (National scale). While the 2010-report also included potential effects on white-tailed eagles, Eurasian eagle owl and waders this geographically extended analysis only covers seabirds. Marine wind farms are a relatively new element in European waters, and at present there have been few investigations carried out to study their short- and long-term environmental effects. While there have been several studies to identify environmental impacts of wind farms in other countries, there is currently only one such study in Norway, on the island of Smoela. So far, four mechanisms have been emphasized with regard to the impact of wind farms on birds: 1) mortality resulting from collisions with wind turbines (tower and wings), 2) avoidance due to interference from installations in operation and from the activity associated with the construction of wind farms; 3) loss and change of habitat, through habitat degradation and fragmentation, and 4) barrier effects, which may increase the flight distance and increase the birds' energy demands. In this report, we have chosen to use a methodology that was developed to evaluate seabird vulnerability to marine wind farms in German waters. This method provides a species-specific vulnerability index (SSI) based on nine factors: flight maneuverability, flight altitude, percentage of time flying, nocturnal flight activity, sensitivity towards disturbance by ship/helicopter traffic, flexibility in habitat use, bio geographical population size, adult survival rate and conservation status. In addition we added a 10’th factor in this analysis; the regional proportions of the national populations of each species involved. Combined with a measure of density or relative proportion of the relevant species in an area, a wind farm sensitivity index (WSI) is created. The WSI can be summed for all species found in the area at different times of the year to give a total WSI for seabirds. The existing data for seabirds in winter and in the breeding season was of sufficient quality to be used for this method. While working with the update of the screening on a National scale we realized that the scope were much more challenging than anticipated. The Norwegian coastline, spanning 13 degrees of latitude, is extremely variable with respect to sea temperatures, sea currents, topography, seabird habitats and the distribution of seabird species (e.g. Barrett et al. 2006; Forsgren et al. 2009). The Barents Sea is known for its large numbers of especially auks, whereas the seabird fauna in the south is dominated by smaller colonies of gulls (Barrett et al. 2006). In order to avoid that the large numbers of seabirds in north completely masked the smaller numbers in south we decided to perform a regional analysis of seabird vulnerability, with the North Sea, the Norwegian Sea and the Barents Sea as the regions analyzed. The results are presented in maps, where the WSI is given for 10x10 km squares. The results demonstrate a clear difference in vulnerability between the regions and the seasons (overwintering, breeding). Compared with the previous analysis (Christensen-Dalsgaard et al. 2010) the present, regional assessment, caused more areas to be defined as vulnerable. Among the areas that were defined as vulnerable in the current analysis many were breeding areas along the Helgeland coast that were defined as important in earlier work (e. g. Systad et al. 2007, Christensen-Dalsgaard et al. 2008). In the North Sea more areas were identified as vulnerable in the wintering season indicating that the regional assessment caused a more correct reflection of vulnerable areas in the North- and the Norwegian Seas. For the Barents Sea the regional assessment caused many areas to display as apparently less important than areas in south- and mid-Norway. This is because the proportional number of a seabird species in an area was compared with the total regional population of that species. Thus, the large numbers of seabirds in the Barents Sea were reduced to relative numbers and, consequently, a loss of a small number of birds in an area with few birds were on the same footing as a loss of a large number of birds in an area with a large number of birds. An assessment of the importance and the consequences of potential loss of seabirds in different areas due to windpower plants is a challenge for the environmental governments. From a biological point of view this is not a satisfactorily way to assess potential effects and consequences. Therefore, the author’s point of view is that it is pertinent to do regional assessments of vulnerability in order to pinpoint important populations and areas on a smaller scale. The current assessment is not, however, intended to replace an assessment on a national scale where also the dispersion and migration of birds is included. Large scale assessments of the effects of given factors will always be imprinted with uncertainties, simply due to the large scale. In the North Sea the same areas that were identified as vulnerable in relation to marine wind farms in Christensen-Dalsgaard et al. (2010) were also identified as vulnerable in the present analysis. The regional analysis, however, implied a higher level of vulnerability in the northern areas during the breeding season. This was caused by the extending of the buffer zone from the Runde into the North Sea. Thus, the great numbers of auks at Runde influenced the vulnerability assessments in the North Sea were the numbers of auks are small. Also the (small) colonies of auks at Einevarden, Klovningen and Veststeinen got a higher vulnerability score in the Nort Sea region in the present assessment. For the overwintering period the coast of Vestfold got a higher vulnerability score due to the presence of marine ducks, and the Oestfold and Jaeren and Boknafjord area got a higher score due to the presence of Great cormorants and Shags. For the Norwegian Sea there were quite big discrepancies between the previous analysis (Christensen-Dalsgaard et al. 2010) and the present one. This was especially pronounced along the Helgeland coast due to the large numbers of breeding great cormorants and Shags. In addition, the seabird colony at Roest got a lower vulnerability score in the present analysis, probably due to the increased vulnerability in other areas.The Barents Sea area was not treated in Christensen-Dalsgaard et al. (2010). From a general knowledge of the occurrence of seabirds in the area it is clear that the regional division of the Norwegian coast give very different results compared to what a national assessment would have done. On a national scale the large number of seabirds in the Barents Sea would have masked many of the important areas in southern Norway. For seabirds at sea the results from the present analysis is comparable with those in Christensen-Dalsgaard et al. (2010). In our study, the analysis of vulnerability is done for separate areas in relation to the presence of birds. However, in the case of extensive development of large numbers of wind farms in close proximity to one another, different and stronger responses can be expected from both individuals and populations of birds than what has until now been documented for smaller offshore wind power plants. During the future development of wind power plants, both off- and on shore, it will be important to not only consider each wind power plant in isolation, but to focus on what their total or cumulative environmental effects will be. It should be noted that our analysis is for guidance only. It is suitable for large-scale evaluations of the vulnerability of areas. To assess the suitability of specific areas for the development of wind power plants, it is, in addition to this report, necessary to study local occurrences of birds and identify important functional areas for seabirds. The basis for the index should also be assessed and reviewed continuously, so that the latest knowledge about the effects of wind farms can be incorporated in later analysis. (Author)

    The project has derived benefits from the earlier Finnish research and development as well as from the experience in the fibre-ash materials for geotechnical applications. The fly ashes used for the project have been taken from the same sources as the fly ashes for the earlier Vaermeforsk project 870: FACE. The project's objective was to develop construction materials based on mixtures of fibre sludge and fly ash for geotechnical applications, and for the final commercialisation of the fibre-ash materials. The mixtures are based on fly ashes from energy production (bark, peat and sludge used for incineration) and on kaolin containing fibre sludge from the paper industry. With help of laboratory tests the project has been searching for fibre ashes with excellent technical characteristics like good frost resistance combined with a good bearing capacity and resilience in geotechnical structures. The project's results has given additional knowledge about alternative road construction materials to construct technically good, sustainable and environmentally friendly roads and other constructions with lower costs than the conventional constructions. The results of laboratory tests have shown that this is possible. However, it has to be verified with help of field tests and pilot constructions. The first tasks of the project were to make choices of the appropriate fibre sludge and fly ashes for the project targets. The laboratory tests have been carried out in the geotechnical laboratory of Ramboll Finland Oy (earlier SCC Viatek Oy, SGT - later in the report SGT). After arrival of all test material in the laboratory the test programme started in order to find out the most optimal fibre-ash mixtures with or without any activator. The most potential mixtures were tested for their geotechnical long-term properties (mainly resistance against climatic load) and for their environmental risk potential. The results comprise of several technically, environmentally and economically potential fibre-ash mixtures and recommendations for their further development with the help of field tests and test construction. The most noteworthy benefits of the fibre ashes as soil construction materials are their elasticity and resistance against permanent deformation. These properties make the fibre-ash materials significantly more frost resistant than the conventional materials. Also, the fibre-ashes are easier and simpler to use in the construction process than the fly ashes because the fibre-ashes are practically dust-tight materials. The results of the project will be background information for the further studies, and for the guidelines and commercialisation of e.g. road construction with fibre ashes.

    The aim was to assess long-term effects of wood-ash and lime application on the soil fauna diversity. The study was made at three sites, Oeringe and Torup in the county of Halland and Asa in the county of Smaaland, 20, 14 and 10 years after treatment, respectively. The soil fauna groups reported here are Enchytraeidae, Tardigrada and Oribatida. Different kinds of wood ash results in very different effects on soil pH despite similar dose. Non-hardened fresh ash increased pH as indicated by the liming potential (ca. 2 tonnes of CaCO{sub 3} correspond to 2,4 tonnes of loose ash). Hardened wood ash (at Asa) had a smaller effect on pH than corresponding amount of lime, and ca. 6 tonnes of ash/ha were needed to obtain the same effects as 3 tonnes of lime. Granulated wood ash (at Torup) had an even smaller effect on pH than the hardened ash at Asa. A preliminary estimate is that 6 tonnes/ha granulated ash correspond to 3 tonnes/ha of hardened ash, 1.5 tonnes/ha of non-hardened loose ash and 1 tonne/ha of CaCO{sub 3}. The results with regard to soil fauna show that individual numbers, species numbers and single species of Enchytraeidae and Oribatid mites are strongly dependent on the ash/lime effect on pH in the topsoil layer. Lime and ash appear to have similar effect on these animal groups provided that the pH effect is similar. Therefore, it is possible to extrapolate conclusions from liming trials to ash trials, provided that the pH effect is known. The Tardigrades did not seem to react on the treatments. We conclude that the effect of wood ash on the diversity of soil fauna investigated depends on the solubility of the wood ash and its effect on soil pH. Depending on the effect on pH, ash application results in (a) decreasing densities but increasing species numbers of enchytraeids, (b) decreasing densities but no change in species numbers of oribatid mites and (c) a strong change in the community structure of both enchytraeids and oribatid mites.

    This report tries to evaluate the importance of the risk perspective in connection with final storage of nuclear waste. The concept 'risk' has different importance for experts and general public, within different research directions and among stakeholders in the nuclear waste issue. The report has been published in order to give an interdisciplinary scientific perspective on the risk concept. The authors have their background in different disciplines: radiation physics, psychology, media- and communications-science. The report treats four different themes: The first theme concerns perspectives on the risk concept and describes various principles for how risks can be handled in the society. The next theme is about comparing various risks. This section shows that risk comparisons can to be done within the framework of a scientific attitude and during certain given conditions. The third theme elucidates results from research about subjective risk, and shows that a large number of factors influence how risks are considered by individuals, and can influence his risk behavior and also how the individual means that the society will make decisions in risk-related questions. The fourth and last theme is about risk communication. Since the risk concept contains many different aspects it is clear that risk should not only be informed about, but also communicated. If a purely mathematical definition of risk was the only valid form, such information, from experts to the citizens, would possibly be sufficient. But since there are other relevant factors to take into consideration (t.ex the individual's own values), a communicative process must take place, i.e. the citizens should have influence on how risks are compared and managed. In the final theme, the authors have chosen to reflect around the themes above, i.e. different perspectives on the risk concept, risk comparisons, subjective risk view and risk communication are discussed.

  17. Efficiency and effect of different soot blowing methods on boilers using different types of fuels; Sotningsmetodernas effektivitet och konsekvenser paa foerbraenningsanlaeggningar foer olika typer av braenslen

    Increased use of recovered wood fuel, waste fuel and new types of wood fuel, have increased the amount of fouling in the superheater and economizer. Deposits in the boilers heat-absorbing banks reduces the boiler efficiency and increases the exit flue gas temperatures. Thus, efficient soot blowing practice is now in focus with the aim of reducing the amount of fouling. This report evaluates the function and efficiency of the commonly used soot blowing methods at boilers in the range of 10 to 130 MW. The investigated soot blowing methods are: steam-, acoustic-, shot-, water-, hammer- and detonation cleaning. Plant experience and data has been acquired from the following six plants: Fortum Hoegdalen, Haesselby and Brista, Stora Enso Hyltebruk, Tekniska Verken i Linkoeping, kraftvaermeverket and C4-Energi, Alloeverket. Participating plants have shown a wide variety in: different boiler designs, different design of superheater and economizer, different kinds of used fuels and different kinds of fouling problems. Soot blowing efficiency is basically a function of three parameters: 1. Characteristics of the deposit regarding to hardness, toughness, homogeneity, amount and coverage, this is often due to the characteristics of the fired fuel. 2. Design of the heat absorbing banks regarding the risk of deposit formation and clogging. 3. Characteristics of the soot blowing method regarding the cleaning effect, bank penetration, high temperature endurance and suitability in different parts of the boiler. These three parameters coincide and together they decide the performance efficiency of the soot blowing method. Used fuel can be divided in to three groups depending on the formed deposits: Firing of mainly wood fuels resulted in no or minor problem with fouling. Firing of waste fuels resulted in hard and tough deposits. Participating waste fired boilers was, however, designed with consideration to these types of deposits and, therefore, these deposits was in reality not a major problem. Firing of recovered fuel types resulted in large amounts of fouling. Boilers originally designed for wood fuels are now more and more firing recovered fuel types. However, their soot blowing equipment and their heat absorbing banks are not designed for these large amounts of deposits. Therefore, fouling is a major problem for these boilers. The heat absorbing banks, mainly the superheater and the economizer, can be designed differently regarding to fouling. In general, straight pipes are used in the superheater but with large amount of fouling, the banks are preferably either hanging or standing. In the economizer it is also common to use flanged piping. Hanging straight tubes, horizontal straight tubes are preferably with large amount of fouling and horizontal flanged tubes are used when little amount of fouling is present. The evaluated soot blowing methods have different properties and are used differently. These methods are: Soot blowing with water is mainly used against hard, ceramic-type of deposits formed at high temperatures mainly before the superheater. Soot blowing with steam is commonly used and can be used both in the superheater and the economizer. At higher temperatures and harder deposits, retractable lances with few nozzles are used, while in the economizer with softer types of deposits, fixed and rotational lances with several nozzles is often used. Hammering is mainly used by waste fired boilers with hanging or standing banks and is a successful practise against hard but brittle deposits. Shot cleaning is mainly used in the economizer when the fouling consists of thick, sintered and dry deposits. Acoustic cleaning can be performed with both audible and infra sound. The method is commonly used against softer deposits at lower temperatures or used as a complement to i.e. steam cleaning. Acoustic cleaning is performed much more often than i.e. steam cleaning, and, therefore, it prohibits the formation of a deposit at an early stage. Detonation cleaning is a relatively new method, which has shown to be efficient against hard deposits. It is, however, used with caution by those boilers that has problems with the formation of a hard permanent deposit during the season. To sum up, several plants can improve their soot blowing equipment by primarily adjusting the soot blowing intervals and determine the change in the exit fume gas temperature. One can also complement existing soot blowing equipment with acoustic or detonation cleaning. However, many boiler fires today fuels with a high risk for the formation of deposits and, therefore, improved soot blowing is the only efficient countermeasure remaining.

  18. Effects of harvest season prolongation on survival and growth of willow; Effekter paa oeverlevnad och tillvaext vid foerlaengd skoerdesaesong av salix

    Willow normally is harvested in Sweden during the winter period, when the plants are in dormancy, the soil is frozen and able to carry heavy machinery, and when the chips can be transported directly to the district heating plants. Mild and wet winters often cause harvest delays and may hamper supply of fuel to the heating plants. During the harvest season 2006/2007 only a minor part of the planned harvest could be performed, which resulted in a one-year delay of harvest of about 3000 hectares of willow. Similar problems occurred during the following harvest season. The above experiences stressed the need for a prolonged harvest season, partly to perform harvests before stem dimensions become too large for conventional harvesters, and partly to guaranty security of supply to the heating stations. Many actors on the market have shown a strong interest in prolonging the harvest season. To test the effects of harvest season, two field trials containing the clone 'Tora' were established on the farms Flosta, Altuna, 25 km north of Enkoeping, and on Teda Risberga, about 10 km south of Enkoeping. The plantation at Flosta was about to be harvested for the first time, while the stand at Teda was going to be harvested for the second time. Both plantations are located on clay soils, representative for the Maelardalen district. At both sites, seven harvests were performed, from mid-September until mid-June. Biomass at harvest and regrowth after one season were determined. A phenology study was performed to assess growth cessation and growth start, and at each of the harvests, leaf biomass also was estimated. Plant survival after harvest was nearly 100% in all cases. There was a high correlation between plant weight at harvest and regrowth during the following season. Regrowth after the different harvest occasions varied and was highest for the harvests under January, March and April at both sites. In Flosta, the September harvest and the late spring harvests were lower than the winter harvests. Teda Risberga displayed the same trends, except for the September harvest, which was at the same level as the winter harvests. This project shows that it is possible to harvest the clone 'Tora' both in late spring when growth has commenced and also early in autumn when the plants are not dormant yet, without increasing the risk for plant mortality. However, biomass production during the first season after harvest may be slightly decreased. Under the circumstances were it is necessary to harvest to prevent shoots from attaining too large dimensions to be harvested conventionally, it is possible to harvest 'Tora' from late September until June, without increasing the risk for plant mortality, but with a risk for a slightly deceased regrowth. These observations are valid for the clone 'Tora' in the Maelardalen district

    We have established a list of lichen- and moss flora of a waterway to be developed for hydropower production (Vangjolo) and in a control water system (Roesgrovi), both in Voss in Hordaland. The waterways have similar bedrock, exposure, vegetation and elevation. To monitor any change in the flora, it was laid out 20 fixed routes from each river systems where low-and moss flora were recorded. To relate this to the monitoring of potential impacts, l flow, humidity, air temperature, water temperature and dew point temperature were logged. It was recorded 66 species total for Roesgrovi and Vangjolo, and 32 mosses, 29 lichens and 5 vascular plants. The results show that the rivers are so similar to the low-and moss flora that they can form the basis for further investigations. This is also shown by the DCA-analyses. The waterways comprises a combination of species with the same requirements as to moisture, and contains species of high and low Ellenberg indicator values for moisture. There is no statistically significant difference between Roesgrovi and Vangjolo in the fixed routes average values. The hydrological and local climatic measurements also show that the river systems are comparable for further study of possible changes after development. (eb)

    This report examines how Norwegian petroleum investments may contribute to develop industry and a more even distribution of income in the receiving states. It also examines to what extent such investments may help to improve social development, humane rights, health, the environment and safety. The study concentrates on Norwegian investments in Angola. Offshore petroleum activities are capital-intensive and technologically demanding industry which often becomes an enclave in countries with a weakly developed industrial basis and few skilled workers. The profit from this industry accounts for a very large part of the export earnings and of the earnings of the public sector while at the same time this sector creates relatively few jobs in the local community. Thus, the income from the petroleum industry is not widely distributed. The petroleum sector tends to increase the growth of income during its development period but then causes little further development. This can be remedied by an economic policy that deliberately smoothes differences and by taking macro-economic measures which prevent overheating of the economy and which creates space for development in the private sector in the mainland economy. This is difficult, and few oil-exporting developing countries have succeeded so far. In Angola it is hardly possible under the current circumstances with civil war and the absence of institutions that work. The report emphasises that oil companies can contribute with knowledge transfer to local employees and the local state oil company. They should also help to extract Angola's resources in the most efficient and environmentally friendly way. But the social and economical development is the responsibility of the local authorities. Norwegian authorities may provide technical and economical aid, if desired, but it is stressed that there should be a clear division of roles between the authorities and the oil companies.

    Corrosion in flue gas appliances installed in small and medium sized biomass fired boiler plants has become a problem in an increasing number of sites around Sweden. A trend seems to be that the problems are greater in those plants that use so called terminal chips than those that utilize more homogeneous fuels. In pace with the increasing number of biomass power plants in the country, the demand for cheaper fuel is increased. Through the increasing number of fuel terminals the market is provided even with biofuel mixes in the form of traditional wood chips mixed with bark, forest residue, sawdust, willow, returned wood, etc. Both users and suppliers of boiler and flue gas systems, and fuel suppliers have currently no clear rules or guidelines for relationships between different chemical properties of fuels, technologies, operating data and material. In this report has experience in the form of questionnaires completed by field visits, interviews of operational personnel and literature studies been compiled from a number of plants using different types of flue gas condensers for increased energy output from various types of bio fuels. The purpose of this assignment is to survey the flue gas condensation plant in biomass fired boiler plants for the presence of corrosion damage made in relation to the use of technologies and fuel qualities. A milestone is that the report will be able to be used to support the selection of materials and appropriate techniques for both new facilities and for the repair and improvement of existing ones. Another objective is to compile existing experience and assessment criteria which are reported in the literature. This report describes some typical construction techniques, whenever applicable harmful images and links to various substances present in fuels, ash and condensate

    The aim of this study was to review existing knowledge on various methods for reclaiming peat winning fields, in order to assess the present and future potential of the afforestation alternative for Swedish fields. From this, a decision on the best use of an existing series of afforestation experiments established after peat winning in central and south Sweden should be made. The study deals with experiences from e.g. growing crops and energy forests, creating artificial lakes, pastures, and berry fields, wetland restoration, and afforestation by planting and by natural seeding from nearby forests. It was concluded that afforestation most likely will be one of the most common after-use alternatives in near future in Sweden, and that priority will be given to extensive afforestation methods. The studies in the afforestation experiments should therefore be focused on (1) the possibilities of natural establishment of seedlings by seeding from nearby forests, (2) the suitability of various tree species for planting, and (3) the need for plant nutrient amendments to secure sustainable site productivity and the possibilities to meet this need by using wood ash as fertilizer. 129 refs

    This report summarizes the present knowledge concerning the impact of automobile exhausts on plants and the research carried out at IVL in this field during the period 1988-1991. The investigations carried out at motorway E6 south of Gothenburg show: * that the concentrations of ethylene are high enough to cause pronounced effects on the bio indicator petunia, * that the ozone concentrations in the vicinity of the motorway are lower than the regional background concentrations, which was reflected in significantly less visible ozone injury on the ozone bio indicator, subterranean clover, close to the motorway after an ozone episode, * that the less ozone sensitive red clover, in contrast to subterranean clover, showed stimulated growth with increasing distance from the motorway, * that there was a tendency towards higher yields for cereals in the vicinity of the motorway, but the extent of and cause for this growth stimulation is not known at present. The effects of metals from catalytic converters is as yet uncertain, as is the understanding of effects of nitrogen oxides. 45 refs, 16 figs, 7 tabs

    Several methods that can be used to estimate the emission of nitrous oxide from arable land are discussed, all of them with their pros and cons. 1 The base for all estimation methods is field measurements, well executed with a technique designed for the production of high quality data. Published field data of good quality were collected from areas in north Europe and America, both from grain and rape crops and unfertilised grasslands where natural background emission is assumed. The compilation shows that grasslands emit in average 0.3 +- 0.1 kg N{sub 2}O-N/ha/year. In crop systems where a high amount of nitrogen is repeatedly added to the soil, the soil N store will contribute to N{sub 2}O emission coming years. This is one reason why emission is higher for unfertilised arable land (where nitrogen have been added previous years) compared to unfertilised grassland, 1 +- 0.1 kg N{sub 2}O-N/ha/year. Fertilised arable lands have higher emission, in average around 3 kg N{sub 2}O-N/ha/year. In comparison, field measurements in Sweden have shown lower emission, 0.6 and 2 kg N{sub 2}O-N/ha/year from clay and sandy soil respectively. 2 The IPCC method is the best known, where the emission from arable land is estimated as a function of added nitrogen. In reality there is no correlation between a low N-addition and the emission of nitrous oxide since the N-addition needs to be high to have influence on the nitrous oxide emission..25 or the new factor 1% of added N has been used in many LCA's as an estimator for nitrous oxide and the uncertainty span of 0,3 and 3% is seldom used. The method underestimates the size of nitrous oxide emission in many systems and cannot estimate a true emission from individual fields. 3 Globally there is a connection between the increase in reactive nitrogen and the increase of atmospheric nitrous oxide, which is the base for a method suggested by Crutzen et al. Nitrous oxide emission has been estimated to be 3-5% of both biological nitrogen fixation and fertiliser production. 4 The complexity of nitrous oxide production has caused attempts to include other influencing factors as well. Two statistical methods and the process model PnET-N-DNDC has been taken as examples. Important for these estimations of emission is the amount of available soil nitrogen and the freezing of soil. Nitrous oxide estimation by these methods results in higher emissions than shown by Swedish field data. 5 Stating and motivating a realistic size of the nitrous oxide emission from agriculture and forestry is important. Therefore field measurements and development of the process model Coup are performed. Coup computes processes in the soil and plant system and has, up to now, mostly been used to understand the processes. From now on it can also be used as a tool for assessing nitrous oxide emission from both forest and agricultural land. Since Swedish field data point to lower emission than the estimation methods provide, we are looking for a method better adapted for the estimation of emissions from Swedish agriculture. We must pinpoint clearly which circumstances lead to the high emissions we want to avoid and, in contrast, which ones give low emissions. For this more field data is of need and process based model calculations to give good answers. If everyone uses a method that shows lower emissions without proving the matter of fact, the total nitrous oxide emission from cropping systems in Europe will be underestimated. The use of the IPCC emission factor often results in lower nitrous oxide emission than 3 kg N{sub 2}O-N/ha/year. Moreover, with the IPCC method fertilised effective cropping systems having a low emission will not get credit since fertiliser addition is the only factor on which emission is calculated. And in a near future the growing agricultural production of food, feed and energy needs a minimum of nitrous oxide emission, which will be ever-increasingly important. I suggest using local data or estimation methods validated on local data for emission assessment from bio-energy cropping systems. If no loc

    The Swedish Radiation Protection Authority has investigated the status of radiation protection in connection with percutaneous coronary interventions (PCI) in Swedish hospitals. A questionnaire was send to hospitals concerning basic radiation protection procedures stated in the Swedish regulations. A questionnaire was also sent out to radiologists and cardiologists and the answers from those who performed interventions were analysed. The study indicates a strong need for improving radiation protection, as an example many hospitals could not present any documents describing methods or radiation protection procedures in connection with these interventions. Moreover, the radiation dose to hands and eyes of the personnel is rarely measured and the fluoroscopic time used for the interventions is not properly analysed. SSI is convinced that many hospitals need to improve radiation protection to meet the demands of the regulations. This could be accomplished by more efficient organized radiation protection work in the hospitals.

    Following the success of the audio video standard (AVS) for 2D video coding, in 2008, the China AVS workgroup started developing 3D video (3DV) coding techniques. In this paper, we discuss the background, technical features, and applications of AVS 3DV coding technology. We introduce two core techniques used in AVS 3DV coding: inter-view prediction and enhanced stereo packing coding. We elaborate on these techniques, which are used in the AVS real-time 3DV encoder. An application of the AVS 3DV coding system is presented to show the great practical value of this system. Simulation results show that the advanced techniques used in AVS 3DV coding provide remarkable coding gain compared with techniques used in a simulcast scheme.

    The reverse osmosis (RO) separation of aqueous organic solutions, such as alcohols, amines, aldehydes, acids,ketones, and esters etc., by PAA (polyacrylic acid)/PSF (polysulfone) composite membrane has been studied. It was found that the separation results for aliphatic alcohols, amines and aldehydes are satisfactory, the solute rejection (Ra) and the volume fluxes of solutions (Jr) for 1000 ppm ethanol, ethylamine and ethyl aldehyde are 66.2%, 61.0%, 84.0% and 0.90×alcohols, amines and aldehydes, and the Ra for n-amyl alcohol, n-butylamine and n-butyl aldehyde reached 94.3%, 88.6%and 96.0%, respectively. Satisfactory separation results (Ra>70%) for ketones, esters, phenols and polyols have been obtained with the PAA/PSF composite membrane. The effect of operating pressure on the properties of reverse osmosis has also been investigated. Analysis of experimental data with Spiegler-Kedem's transport model has been carried out and the membrane constants such as reflection coefficient σ, solute and hydraulic permeabilities ω and Lp for several organic solutes have been obtained.

    2006-01-01

    Adaptive frame/field coding techniques have been adopted in many international video standards for interlaced sequence coding. When the frame/field adaptation is applied on the picture level, the coding efficiency is improved greatly,compared with the pure frame coding or the pure field coding. The picture-level adaptive frame/field coding (PAFF) selects frame coding or field coding once for one picture. If this frame/field adaptation is extended to Macro Block (MB) level, the coding efficiency will be further increased. In this paper, a novel MB-level adaptive frame/field (MBAFF) coding scheme is proposed. In the proposed MBAFF scheme, the top field of the current picture is used as a reference. The experiments are implemented on the platforms of Audio Video coding Standard (AVS) base profile and H.264/AVC, respectively. On the AVS platform, 0.35dB gain can be achieved averagely, compared with AVS1.0 anchor. On the H.264/AVC platform, 0.16dB gain can be achieved averagely, compared with MBAFF scheme of H.264/AVC. Additionally, an extensive subjective quality enhancement can be achieved by the proposed scheme.

    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.

    The use of fuel pellets, mainly produced from sawdust and shavings from the Swedish sawmill industry, has increased during the 1990s among small-scale users such as private houses as well as large-scale users such as thermal power stations. During the last years this increase has continued for small-scale use. Due to a significant increase of the pellet prices the last couple of years the increase for the large-scale users seems to have stopped. It is reasonable to believe that these higher prices depend mostly on lack of raw materials for the fuel pellet production. The greater part of sawdust from Swedish saw mills is used in the pellet industry, the board industry or as an internal fuel. It is reasonable to assume a small increase of present raw material available for pellet production without a further decrease in the use for the board industry. Another sawmill by-product, dry chips, may increase in importance as a fuel pellet raw material and give a small contribution while the green chips should be for use in the pulp industry only. If the use of fuel pellets should increase there is a need for new raw materials. In the short-term, thinning material and cull tree could be alternatives that could give pellets with similar characteristics as present fuel pellets. For large-scale consumers with greater ability to handle problems concerning ash, such as sintering and fouling, as well as particle and gaseous emissions a further choice of raw materials could be possible, such as bark, peat and logging residues. In the longer term energy crops could be used as well as lignin, derived from energy effective pulp industry and from possible large-scale production of ethanol from woody biomass. Nearly all of the different raw materials studied in this review have higher amounts of substances not desirable in combustion such as potassium, chlorine and nitrogen. However, pelletizing gives an unique opportunity to mix different raw materials and possible additives in order to obtain a fuel more optimized than the raw materials on there own.

    Since the start of the nuclear power era studies have been performed of how to utilise the uranium energy resource in the most effective way. Only about one percent of the energy potential of uranium is utilised in the light water reactors of today. To improve the utilization other types of reactors are needed. With fast reactors theoretically 50-100 times more energy can be extracted from the uranium. This will require reprocessing of the uranium and multiple recycling of the plutonium. Plutonium and uranium can also be recycled in light water reactors, but this will only improve the uranium utilisation by about 20 %. Recycling of plutonium on a routine basis is presently only done in France. The development of fast reactors has been going on since the end of the 1940ies. During the 1970ies the planning was that a large number of fast reactors and their associated fuel cycle facilities would be in operation by the year 2000. The development has, however, for different reasons been much slower than planned. The general assessment today is that fast reactor, if they will be realised, will hardly give an important contribution to energy production until after 2050. Nuclear power production has instead been dominated by light water reactors similar to the ones in use in Sweden. Light water reactors are believed to continue to dominate during the next decades. To start a fast reactor system plutonium (or highly enriched uranium) will be needed. Such plutonium is contained in spent nuclear fuel from light water reactors. This raises the question: Should the spent nuclear fuel be stored so that the potential energy resource in the fuel can be used in the future instead of disposing of it as a waste? The answer to this question will depend on when the material will be useful, i.e. when fast reactors have been introduced on a large scale. It will also depend on the demand for plutonium at this time, i.e. will plutonium be a scarce redundant resource at this point of time. In this context it should be considered that fast reactors will generate their own plutonium, as breeder reactors. Plutonium from other reactors will thus only be needed for the first years of operation. To provide a basis for the answer to the question if the Swedish spent fuel is a resource or a waste this report provides an overview of the present development status for fast reactors and their potential for large scale commercial use. It further describes the impact on the Swedish system for management of spent nuclear fuel if the fuel were to be reprocessed and the uranium and plutonium reused as fuel for fast reactors or for the present reactors.

    The new Norwegian hydroelectric power station Hekni Power Station in the river Otra began operation in the autumn of 1995. Out of consideration for the landlocked salmon in the Byglandsfjord, valuable and nationally deserving of preservation as it is, the tunnel was gradually filled with water so as to avoid large amounts of suspended sediments downstream. During start-up, several environmental investigations were made, as discussed in this report: registrations and analyses of the water from Otra, experimental exposure of landlocked salmon, assessment of wild fish and collection of bottom animals from river stretches exposed to suspended sediments and from unexposed control stretches. Exposed salmon show clear evidence of typical gill changes due to acidification while there is no evidence of changes caused by suspended sediment particles. The changes in population densities of wild fish and bottom animals from before start-up to after start-up is primarily related to the altered water discharge. However, the absence of groups of particle sensitive bottom animals after exposure may be due to particle emission from the power station. The chemically unstable particles may have temporarily increased the pH and calcium concentration and reduced the concentration of unstable aluminium in the most affected part of the river system, while the particle level itself may have been too low to cause noticeable effects on fish. The extent to which the bottom ecology may have been damaged is not sufficiently well known. 34 refs., 8 figs., 6 tabs.

    In several investigations it has been shown that kaolin works well as an anti-agglomerating and anti-ash sintering agent in combustion of bio-fuels with a potassium rich ash in fluidised bed boilers. Combustion tests have shown that the kaolin addition may result in an ash melting temperature that is a couple of hundred degrees centigrade higher than for the original ash. This way the kaolin hinders the fouling of super heater surfaces by sticky ash. Many boiler owners treat their wood fuel ash with the aim to recycle it to forest soil as a nutrient source and acid neutralising agent. Therefore it was considered important to investigate if an addition of kaolin in the boiler would have a negative influence on the ash leaching properties. Thus, the aim of the project was to investigate the hardening reactions and leaching properties of normal wood ash and wood ash produced with addition of kaolin. The ash samples were produced in the same boiler and in similar combustion conditions. It was especially interesting to study if the ash would contain soluble aluminium due to the kaolin addition since aluminium in solution may have negative effects on the eco system. The results showed that an important difference between the normal fly ash and the fly ash with kaolin was that the release of potassium i leaching was decreased due to the kaolin addition, especially at high pH levels. This is positive, since potassium normally is released very fast in the forest. In addition, the kaolin containing ash has a faster initial setting/hardening process than the normal ash. The structure of the hardened ash particles is also more durable than that of the normal ash. This is also a positive effect since it indicates that it could be possible to handle the hardened ash after a shorter storage period. However, it has not been investigated if this effect remains in large scale operation and in a longer time perspective. The acid neutralising capacity of fly ash with kaolin is, calculated per kg of ash, somewhat lower that for the usual ash. The kaolin is accumulated in the fly ash since it has such a small particle size and thus dilutes the fly ash and lowers its content of acid neutralising components. This can be compensated for by spreading more ash per hectare. The leaching of aluminium from the kaolin containing ash was low at all pH levels studied (4- 13). Consequently, spreading of such an ash is not considered to pose any risk for the environment. In addition, the leaching of trace metals from the ash was not affected negatively by kaolin addition

    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

    The objective of the present study was to evaluate effects of wood-ash application (3.3 and 6.6 tonnes d.w. self-harden crushed wood ash ha-1) in forests on drained peatlands in southern Sweden. Tree growth (three sites) and fluxes of greenhouse gases (one site) were measured in field experiments. In the two experiments (Anderstorp and Bredaryd) in Scots pine stands (Pinus sylvestris L.) on oligotrophic mires, tree growth increased significantly during the seven-eight year long effect periods after ash application. In an earlier study in Anderstorp, the annual emissions of CO{sub 2}, CH{sub 4} and N{sub 2}O from the peat were shown to be unaffected by the ash application. In Skogaryd, a Norway spruce stand (Picea abies L. Karst.) on a minerotrophic mire, the growth was indicated to increase during the five-year effect period. In the same experiment, the previously found reduction in emissions of both CO{sub 2} and N{sub 2}O during the first two years after ash application were no longer significant, although the emissions where lower, for N{sub 2}O only in the high dose ash treatment. CH{sub 4} was unaffected during the whole observed period. During the first five years, application of 3-6 tonnes d.w. crushed wood ash ha-1 in the two studied forests on drained peatlands did not render in an increased Global Warming Potential (GWP), but rather a reduction

    Inorganic nanoparticles play a very important role in the fabrication and regulation of desirable hybrid structures with block copolymers. In this study, polystyrene-b-poly(acrylic acid) (PS48-b-PAA67) and oleic acid-capped CdSe/CdS core/shell quantum dots (QDs) are coassembled in tetrahydrofuran (THF) through gradual water addition. QDs are incorporated into the hydrophilic PAA blocks because of the strong coordination between PAA blocks and the surface of QDs. Increasing the weight fraction of QDs (ω = 0-0.44) leads to morphological transitions from hybrid spherical micelles to large compound micelles (LCMs) and then to bowl-shaped structures. The coassembly process is monitored using transmission electron microscopy (TEM). Formation mechanism of different morphologies is further proposed in which the PAA blocks bridging QDs manipulates the polymer chain mobility and the resulting morphology. Furthermore, the size and size distribution of assemblies serving as drug carriers will influence the circulation time, organ distribution and cell entry pathway of assemblies. Therefore, it is important to prepare or isolate assemblies with monodisperse or narrow size distribution for biomedical applications. Here, the centrifugation and membrane filtration techniques are applied to fractionate polydisperse coassemblies, and the results indicate that both techniques provide effective size fractionation.

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.

    This work is focused about the spectroscopic properties of a polymer material which consists of Polyacrylic acid (Paa) doped at different concentrations of Europium ions (Eu{sup 3+}). They show that to stay chemically joined with the polymer by a study of Nuclear Magnetic Resonance (NMR) of {sup 1} H, {sup 13} C and Fourier Transform Infrared Spectroscopy (Ft-IR) they present changes in the intensity of signals, just as too when this material is irradiated at {lambda} = 394 nm. In according with the results obtained experimentally in this type of materials it can say that is possible to unify chemically the polymer with this type of cations, as well as, varying the concentration of them, since that these are distributed homogeneously inside the matrix maintaining its optical properties. These materials can be obtained more quickly and easy in solid or liquid phase and they have the best conditions for to make a quantitative analysis. (Author)

    Hemoglobin (Hb) was immobilized in poly-allylamine (PAA) film onto the gold electrode by layer by layer (LBL) method. The modified electrode exhibited a pair of well-defined peaks during cyclic voltammetry, which was attributed from the direct electron transfer of heme proteins. The immobilized Hb showed an excellent electrocatalytical response to the reduction of hydrogen peroxide. The sensor exhibited a fast response and high sensitivity. Through the use of optimized conditions, the linear range for H{sub 2}O{sub 2} detection was from 2.5 x 10{sup -6} M to 5 x 10{sup -4} M with detection limit of 0.2 {mu}M. The proposed biosensor showed long-lasting stability and excellent reproducibility.

    The second generation Audio Video Coding Standard (AVS2) is the most recent video coding standard. By introducing several new coding techniques, AVS2 can provide more efficient compression for scene videos such as surveillance videos, conference videos, etc. Due to the limited scenes, scene videos have great redundancy especially in background region. The new scene video coding techniques applied in AVS2 mainly focus on reducing redundancy in order to achieve higher compression. This paper introduces several important AVS2 scene video coding techniques. Experimental results show that with scene video coding tools, AVS2 can save nearly 40%BD⁃rate (Bjøntegaard⁃Delta bit⁃rate) on scene videos.

    A number of test roads and test areas with processed municipal solid waste incinerator bottom ash, here called MSWI gravel, have been built in Sweden during the last 10-15 years. The main purpose of the projects reported here was to take advantage of the existing test roads to increase the knowledge of the long-term strength and environmental impact of MSWI gravel, when it is used as a road material. Two test roads with MSWI gravel in the sub-base were monitored through falling weight deflectometer (FWD) measurements and, for one of the roads, by means of sampling and analyses of groundwater and leachate within and along the road. The first road, constructed in 1998, is named Toerringevaegen and is situated outside Malmoe in the south of Sweden. The second road, Daava test road, was constructed in 2001 and is situated outside Umeaa in the north of Sweden. The roads were monitored regarding strength from 2004 to 2008 and Daava test road was also monitored regarding environmental impact from 2006 to 2008. For both roads, comparison was made over time and between the test sections with MSWI gravel and reference sections with crushed rock. Comparison was also made with results from previous studies on these test roads, resulting in a uniquely long monitoring period. The results from Toerringevaegen show that the road section with MSWI gravel in the sub-base retains its strength after several years. The three measurements performed at the Daava road revealed an initially decreasing strength and then a stabilisation. As in previous studies, the strength of the MSWI gravel was found to be about 70% of that of the crushed rock, which has to be taken into account in the design phase. It was concluded that regarding the strength properties MSWI gravel is suitable as sub-base material if the road is properly designed. It can also be used as a filling material, in embankments and as a capping layer. This confirms the conclusions from previous studies. The results from the leachate analyses showed increased cumulative leaching of calcium and sulphate from both sections at the Daava test road, which was surprising. Furthermore, most compounds leached in greater amount from the reference section than from the test section. There was a significant decrease in the leaching of copper, TOC, chloride and sodium over time from the test section, while the decrease of chromium leaching was not as significant. During the first years after construction, the test section leached greater amount of organic compounds analysed than the reference section did, but the concentrations in the leachates decreased significantly and after five-six years they were comparable with those of the reference section. During the last years, the concentrations of organic acids in the leachates from the reference section were higher than in the leachates from the test section. The reason for this is unknown. When results from previous laboratory leaching tests on the MSWI gravel used were compared with the newly proposed maximum values for waste to be used in construction works (general use) and with current limit values for waste disposed in landfills for inert waste, it was clear that chloride, sulphate and copper and initially to some extent chromium were critical compounds. However, all compounds with proposed or fixed limit values were not analysed in the previous study. Comparison between the leachates from the test section and results from previous laboratory leaching of the MSWI gravel showed significantly different patterns. This should be taken into account in the assessment of potential use

    PAA was prepared by the situ polymerization of AA with various neutralization degrees in PVA solution under the action of initiator and crosslinker and PVA-PAA blended membrane was prepared by the solution casting method. PVA-PAA-KOH alkaline polymer electrolyte was activated by the alkaline solution. The morphology and structure of the polymer electrolyte were characterized by means of SEM, XRD and FT-IR. The electrochemical properties were represented by the AC impedance and the cyclic voltammetry. The results indicated that a homogeneous PVA-PAA blended membrane was successfully obtained. The increased water content of the membrane and the decreased crystallinity of the PVA owed to the presence of PAA. The maximum ionic conductivity of the electrolyte reached to 3. 55 X 10-2 S/cm. The alkaline polymer electrolyte with 7 : 3 mass ratio of PVA : AA could achieve a good synthetical property with electrochemical stability window more than 2V and could meet the demands of MH-Ni battery.%采用溶液浇铸法,向PVA溶液中加入不同中和度的AA,在引发剂、交联剂的作用下,经原位聚合得到PVA-PAA共混膜;接着采用碱液活化法,制备了PVA-PAA-KOH碱性聚合物电解质膜.通过扫描电镜、X射线衍射、红外光谱等测试手段研究了聚合物共混膜的形貌与结构,同时采用交流阻抗、循环伏安法表征聚合物电解质膜电化学性能.研究表明,成功制备了均相PVA-PAA共混膜,同时PAA的合成可以提高体系的含水量以及降低PVA的结晶度.电解质膜的离子电导率最大可达3.55× 10-2S/cm,PVA-AA配比为7∶3的碱性聚合物电解质膜综合性能最优,电化学稳定窗口2V以上,能够满足镍氢电池的要求.

    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.

    The chemical composition of runoff from a wood ash fertilized catchment in central Sweden have been studied during eight years after the treatment. The effects of the ash treatment was compared with a 12ayear long reference period and a reference catchment close to the ash treated catchment. The ash treated area was earlier (winter 1980/81) whole-tree-harvested to 90 %. At the same time the reference area was stemwood harvested on 60 % of the area. Both areas were planted with spruce and pine. Granulated ash was spread on the whole-tree-harvested area, by helicopter, on two occasions (1aton per hectare in May 1989 and 2 tonnes per hectare in October 1991). During the first ash application a marked peak in K concentration was observed. The second ash application caused a high peak in K concentration. Short-lived peaks was also observed for pH, electric conductivity, ANC, Mg, Na and Cl. Significant increases of pH, electric conductivity, Ca, K and Cl was observed in runoff water from the ash treated area during the 8-year-period after the last ash spreading. However, during the same period concentrations of NH4-N, N03-N and total N have shown a relative decrease in runoff water from the ash treated area, compared to the reference area.

    The objective of the present study was to evaluate effects of wood-ash addition on drained peatlands in southern Sweden. Tree growth, greenhouse gases, peat properties, microbial biomass and processes, understory vegetation and groundwater chemistry were measured in three field experiments (some variables were not measured in all experiments): (i) 168 Perstorp, an oligotrophic mire with Scotch pine (Pinus sylvestris L.), where 2.5 tonnes d.w. of wood ash/ha (2.5WA) was added in 1982; (ii) 273 Anderstorp, also an oligotrophic mire with Scots pine, where 3.3 tonnes d.w. crushed ash/ha (3.3KA) and 6.6 tonnes d.w. crushed/ha (6.6KA) was added in 2003; (iii) 278 Skogaryd, a minerotrophic mire with Norway spruce (Picea abies L. Karst.), where the same doses of crushed ash as in Anderstorp were added in 2006. Untreated controls were included in all experiments. At Anderstorp, increased tree growth was indicated, at least in the treatment with the highest ash dose during the first five years after treatment. The annual emissions of CO{sub 2}, CH4 and N{sub 2}O from the peat were unaffected. At Skogaryd, the growth was unaffected and the emissions of both CO{sub 2} and N{sub 2}O were reduced during the first two years after treatment. In general, the significant ash effects (2.5WA and 3.3KA evaluated) on peat characteristics, microbial biomass and processes were found in the upper soil (0-5 cm) at the recently treated sites (Anderstorp and Skogaryd), and at greater depths (5-30 cm) at Perstorp, where the ash was added 25 years ago. In the ash treatment at Perstorp, there was a shift in the plant community structure and a decrease in species diversity of the understory vegetation. However, at this point of time, the forest stand had become substantially denser than on the control plots. Hence, these effects on the understory vegetation may have been an indirect effect of the ash-induced altered tree stand properties. In Skogaryd, no shift in the plant community was found, but an increase in species diversity was detected two years after the application of 6.6KA. In Anderstorp, no effect on the understory vegetation was found. The wood-ash application at Skogaryd resulted in very few statistically significant effects on the 43 measured chemical variables in the groundwater. High background concentrations of for instance B, Ca, Mg and PO4-P probably contributed to this. During the first five years, addition of 3-6 tonnes d.w. crushed wood ash/ha on the studied drained peatlands did not render in an increased Global Warming Potential (GWP), but rather a reduction

    2000-11-01

    The aim of the project 'Adaptation of Wood Ashes to Recycling' is to evaluate a new technique - roll pelleting - for making wood ash suitable for reuse as a fertiliser for woodland. The project is being carried out at the forest product companies AssiDomaen and Stora Enso. The main financier is the Swedish National Energy Administration. Other financiers are AssiDomaen, Stora Enso, The Thermal Engineering Research Institute and The Forestry Research Institute of Sweden. The project has involved the construction of a full-scale roll pelleter in a mobile container and its trial operation at two Swedish pulp and paper mills. The leaching properties of the ash products were studied with a laboratory method. In addition, the effects of ash fertilisation with these products are being studied in a four-year field trial. Effects on soil pH, nutrient supply, soil water chemistry and ground vegetation are being evaluated by The Forestry Research Institute of Sweden and will be reported separately in the year 2003. In a laboratory prestudy, the leaching properties of pellets from twelve different ash products made in a laboratory prototype machine were evaluated. The ash products were made from residues from the AssiDomaen Froevi mill and the Stora Enso Fors mill. Fly ash from Froevi was used alone and mixed with green liquor sludge and lime sludge respectively. Fly ash from Fors was also used alone and mixed with coating colour. The laboratory method used for the evaluation of leaching properties is the method developed by IVL The Swedish Environmental Research Institute Ltd. The results show that the progress of the leaching of roll pelleted ash is significantly slower than for the corresponding crushed product and a reference lime product. The speed of leaching, measured as acid neutralisation capacity, ANC, was significantly lower for the roll pelleted ash compared to self-hardened and crushed ash products. Because of the high content of calcium, lime has on the whole, a greater acid neutralisation capacity. Wood ash differs from lime in that it contains a substantial amount of nutrient elements essential for the forest. The acid neutralisation capacity of the roll pelleted ash was still the same after 100 days of laboratory leaching. The acid neutralisation capacity of self-hardened and crushed ashes usually ceases already after 30 days. It is likely that a well-hardened roll pelleted ash product can, without any great risk of serious damage to ground vegetation, be recycled to the forest during the clearcut stage as a compensation fertiliser following biofuel harvesting. Neither increased nitrification nor leaching of nitrate from soil water is likely to occur. Potassium is considered to be an element that is easily leached from ash. In our laboratory leaching study, on the other hand, as much as 61 % of the original potassium content was still present in the roll pelleted ash after 100 days. The roll pelleting machine has been running a little more than six months at the two mills. In total 1500 tonnes of pellets have been produced. The main part is pellets solely from ash, however, mixtures of ash and lime sludge and ash and green liquor sludge, respectively, have also been pelleted. Our experiences of the roll pelleting machine are very good. The ash products seem well suited to recycling back to the forest. The machine has a production capacity of five tonnes per hour, indicating a production capacity of 10,000 tonnes per year. The running costs, including costs for personnel, spare parts and internal transports, amounted to 87 SEK per tonne of dry ash (i.e. 61 SEK per tonne of ash with 30 % water content) during the long term test. These are low costs compared to other agglomeration techniques. The roll pelleting technique has worked very well on a large scale without any further technical development. As this machine was the first of its kind some adjustments and minor changes were made in the machine and container during the course of the project. Further adjustments have been suggested in our report. Beside this project, 2110 tonnes of roll pelleted ash have been spread in a 70 hectare forest area. The pellets were evenly distributed, at three tonnes per hectare, with a tractor equipped with a disc fertiliser spreader.

    Spherical calcium carbonate composite is synthesized in the solution of amphiphilic block copolymer of polystyrene(PS) and poly(acrylic acid)(PAA). SEM and XRD measurements show that the diameter of the particulates decreases with the augment of the PS-b-PAA concentration, crystalline in the composite is calcite and its morphology as well as the structure is changed too. TG-DTA together with IR analysis is applied to investigating the thermal dynamic behavior of the composite. The results show that the composite is mainly composed of two phases, that is, the nano- crystalline calcium carbonate and the PS-b-PA-Ca composites. PS phase decomposes first with a large heat release at about 330℃. However, the PAA chains have relatively high thermal stability, probably due to the structural Ca-O bond, and decomposes at above 400℃. Matching opinions are used to explain the possible reasons for the regular as well as the particular characteristics of the composite corresponding to a certain copolymer concentration.

  11. In vitro release of clomipramine HCl and buprenorphine HCl from poly adipic anhydride (PAA) and poly trimethylene carbonate (PTMC) blends.

    Controlled drug-delivery technology is concerned with the systematic release of a pharmaceutical agent to maintain a therapeutic level of the drug in the body for modulated and/or prolonged periods of time. This may be achieved by incorporating the therapeutic agent into a degradable polymer vehicle, which releases the agent continuously as the matrix erodes. In this study, poly trimethylene carbonate (PTMC), an aliphatic polycarbonate, and poly adipic anhydride (PAA), an aliphatic polyanhydride, were synthesized via melt condensation and ring-opening polymerization of trimethylene carbonate and adipic acid, respectively. The release of clomipramine HCl and buprenorphine HCl from discs prepared with the use of PTMC-PAA blends in phosphate buffer (pH 7.4) are also described. Clomipramine HCl and buprenorphine HCl were both used as hydrophilic drug models. Theoretical treatment of the data with the Peppas model revealed that release of clomipramine HCl (5%) in devices containing 70% PTMC or more followed a Fickian diffusion model. However, the releases of buprenorphine HCl (5%) in the same devices were anomalous. For devices containing 50% and more PAA, surface erosion may play a significant role in the release of both molecules.

  12. Investigation of PAA/PVDF-NZVI hybrids for metronidazole removal: synthesis, characterization, and reactivity characteristics.

    For the first time, the removal process of metronidazole (MNZ) from aqueous solutions over nano zerovalent iron (NZVI) encapsulated within poly(acrylic acid) (PAA)/poly(vinylidene fluoride) (PVDF) membranes was reported. The resultant composite (PPN) demonstrated high reactivity, excellent stability and reusability over the reaction course. Such excellent performance might be attributed to the presence of the charged carboxyl groups in PVDF membrane support, which could enhance NZVI dispersion and improve its longevity. Results showed that a lower initial concentration and higher reaction temperature facilitated the removal of MNZ by PPN, and that the acidic and neutral conditions generally exhibited more favorable effect on MNZ removal than the alkaline ones. Kinetics of the MNZ removal by PPN was found to follow a two-parameter pseudo-first-order decay model well, and the activation energy of the MNZ degradation by PPN was determined to be 30.49kJ/mol. The presence of chloride ions slightly enhanced the reactivity of PPN with MNZ, whereas sulfate ions inhibited its reactivity. In addition, MNZ degradation pathways by PPN were proposed based on the identified intermediates. This study suggests that PPN composite possessing excellent performance may be a promising functional material to pretreat antibiotic wastewaters.

  13. Frequency-dependent magnetic susceptibility of magnetite and cobalt ferrite nanoparticles embedded in PAA hydrogel.

    Chemically responsive hydrogels with embedded magnetic nanoparticles are of interest for biosensors that magnetically detect chemical changes. A crucial point is the irreversible linkage of nanoparticles to the hydrogel network, preventing loss of nanoparticles upon repeated swelling and shrinking of the gel. Here, acrylic acid monomers are adsorbed onto ferrite nanoparticles, which subsequently participate in polymerization during synthesis of poly(acrylic acid)-based hydrogels (PAA). To demonstrate the fixation of the nanoparticles to the polymer, our original approach is to measure low-field AC magnetic susceptibility spectra in the 0.1 Hz to 1 MHz range. In the hydrogel, the magnetization dynamics of small iron oxide nanoparticles are comparable to those of the particles dispersed in a liquid, due to fast Néel relaxation inside the particles; this renders the ferrogel useful for chemical sensing at frequencies of several kHz. However, ferrogels holding thermally blocked iron oxide or cobalt ferrite nanoparticles show significant decrease of the magnetic susceptibility resulting from a frozen magnetic structure. This confirms that the nanoparticles are unable to rotate thermally inside the hydrogel, in agreement with their irreversible fixation to the polymer network.

    1992-11-01

    The basic anatomical substrate of enhanced A-V nodal conduction, manifesting or not as Lown-Ganong-Levine syndrome, is still a controversial issue. We describe the case of a 34-year-old man who presented episodes of ventricular fibrillation. Electrophysiological studies showed that the AH interval was 55 ms, and increased by only 20 ms at paced cycle lengths of 300 ms; atrial pacing induced atrial fibrillation, with a shortest RR interval of 240 ms. Despite verapamil therapy, this patient died suddenly at home. Histological study disclosed a severe A-V node hypoplasia that was evidently congenital in nature; the rest of the conduction system was normal, and no accessory A-V pathways were present. We suggest that enhanced A-V nodal conduction in this patient was due to the developmental defect in the A-V node; this abnormality caused a loss of specific impulse-delaying function, and thus allowed rapid, unfiltered atrial impulses to reach the lower A-V junction and ventricles.

    As to the complexity process of choosing best probable encoding mode in AVS intra prediction,we proposed a fast intra predic-tion encoding algorithm.With the analysis of AVS intra prediction encoding theory and its implementation in reference software GDM2.1,we derived the threshold of zero coefficient block determination.The fast algorithm determines whether or not the current block is a zero coeffi-cient block according to its threshold discriminant condition.For zero coefficient block,it encodes cbp element directly and terminates intra prediction encoding in advance,which avoids the consequent complex process.As for the non-zero coefficient blocks,the fast selection algo-rithm associating the time domain SAD and the frequency domain SATD is used,which excludes 40% to 80% impossible prediction modes, and the rate distortion function is applied to the remained prediction modes to select the best prediction mode.It was verified through experi-ment that when PSNR (peak signal-to-noise ratio)decreased within 0.25db and bits rate increased within 2%,the time of AVS encoding de-creased over 40%,and the encoding efficiency was largely improved as well.%针对 AVS(Audio Video code Standard)帧内预测中选择最优编码模式流程复杂的问题,提出一种快速帧内预测编码的算法。通过分析 AVS 帧内预测编码的原理及其在参考软件 GDM2.1中的代码实现,推导出判定零系数块的阈值。该快速算法根据零系数块的判定阈值条件判定当前块,对于零系数块,直接编码 cbp 元素,提前中止帧内预测编码,避免了后续的复杂流程;对于非零系数块,采用时域 SAD(Sum of Absolute Difference)与频域 SATD(Sum of Absolute Transformed Difference)相联合的快速选择算法,排除了40%~80%的不可能预测模式,对余下的模式采用率失真代价函数的方法选取最佳预测模式。经实验验证,在 PSNR(Peak Sig-nal to Noise Ratio)降低0

    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.

    Hva er vi villige til å betale for en aksje? ”Price is what you pay, but value is what you get” av Professor Stephen H. Penman i boken ”Financial Statement Analysis and Security Valuation” 2010, poengterer at en aktiv investor ser på prisen for en aksje som kostnaden ved en investering, og ikke verdien av en aksje. I denne utredningen ønsker vi å utfordre markedsverdien til REC, og undersøke om aksjen er over eller underpriset i forhold til børsverdi. Dette har vi gjort ved å foreta en f...

    OpenAIRE

    Solli, Maria Sund

    2015-01-01

    Rørledninger er som blodårer i olje- og gassutvinningen, og vi har mange tusen km med rørledninger bare på norsk sokkel. Integriteten av rørledninger er utfordrende for olje- og gassindustrien. For å kunne sikre integriteten må man derfor utføre inspeksjon og overvåkning av rørledningene, noe som må gjøres rutinemessig gjennom hele levetiden. Inspeksjon kan utføres både utvendig og innvendig. Ved innvendig inspeksjon utgjør pigging en vesentlig rolle. I piggbare rørledninger kan piggen betrak...

    Development of novel nano-drug delivery systems (NDDS) that can transport anticancer drugs into cell nuclei is still a highly desirable strategy for reversing multi-drug resistance (MDR) in cancer therapy. Herein, we designed and prepared a novel NDDS, designated S@L NPs, in which several smaller nanoparticles are contained within a larger nanoparticle. Our S@L NPs (CS/PAA/VP-16@TPGS/PLGA NPs) possess a structure in which smaller nanoparticles (Chitosan-Poly(acrylic acid) nanoparticles, CS/PAA NPs) containing the drug etoposide (VP-16) are loaded within a larger nanoparticle (Vitamin E d-a-tocopheryl polyethylene glycol 1000 succinate-modified poly(lactic-co-glycolic acid) nanoparticles, TPGS/PLGA NPs). The system utilizes intracellular pH gradients to achieve pH-sensitive sequential release within different intracellular domains of MDR cells. S@L NPs could be triggered to degrade and release CS/PAA/VP-16 NPs in the acid environment of the cytosol, endosomes or lysosomes, and CS/PAA/VP-16 NPs were capable of entering the nucleus through nucleopores. It is significant that CS/PAA/VP-16 NPs exhibit disaggregation in the alkaline environment of the nucleus and thereby release the contained anticancer drug. Further mechanistic studies showed that CS/PAA/VP-16 NPs escaped retention and degradation within lysosomes and protected the drug from P-glycoprotein-induced efflux. Simultaneously, S@L NPs enhanced the anticancer effect of the loaded drug by inducing autophagy and apoptosis of MDR cells. This novel NDDS may provide a promising platform for nuclear drug delivery for reversing MDR. PMID:27289313

    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)

    Dielectric properties of PAA-g-PEO-7% solutions with different counterions were measured as a function of concentration and temperature over a frequency range of 40 Hz to 110 MHz. After the contribution of electrode polarization effects was subtracted, the dielectric spectra of PAA-g-PEO-7% solutions showed three relaxation processes in the experimental frequency range, named low-, mid-, and high-frequency relaxation. The observed three relaxations were strictly analyzed by using the Cole-Cole relaxation function, and the dielectric parameters (dielectric increment Δε and the relaxation time τ) were obtained. The scaling relation of dielectric increment and relaxation time of high frequency with concentration C(p) were obtained and compared with the predictions of scaling theories. The information on the dynamics and microstructure of PAA-g-PEO-7% was obtained. Using different counterion species, the mid- and high-frequency relaxation mechanisms were attributed to the fluctuation of condensed counterions and free counterions, respectively, and the low-frequency relaxation was considered to be caused by the interface polarization of a complex formed by the hydrogen bonding between carboxylic group of PAA and ether oxygen on the side-chain PEO. In addition, by means of Eyring equation, the thermodynamic parameters, enthalpy change ΔH and entropy change ΔS, of the three relaxations were calculated from the relaxation time and discussed from the microscopic thermodynamical view.

  4. Viktigheten av fysisk aktivitet og trening blant eldre

    Full Text Available Regelmessig fysisk aktivitet er viktig for eldres helse. Sammenhengen mellom en fysisk aktiv livsstil og helsegevinster som forebygging av sykdom, opprettholdelse av uavhengighet og økt livskvalitet er godt dokumentert (ACSM's Position Stand 1998; Spirduso & Cronin, 2001; Taylor et al., 2004. Hensikten med denne oversiktsartikkelen er derfor å redegjøre for viktigheten av regelmessig fysisk aktivitet og trening i aldringsprosessen, samt utdype sammenhengen mellom en fysisk aktiv livsstil og fysisk funksjon blant eldre. Basert på en nasjonal multisenterstudie (Anderssen et al., 2009, tilfredsstilte 20% voksne og eldre (20-85 år de nasjonale anbefalinger om 30 minutter med daglig fysisk aktivitet. Kun 12% i den eldste aldersgruppen (80-85 år tilfredsstilte anbefalingene. Totalt fysisk aktivitetsnivå, målt ved hjelp av akselerometer, ble redusert med økende alder, hvor de eldste (80-85 år hadde 50% lavere aktivitetsnivå sammenlignet med de yngste (65-69 år (Lohne-Seiler et al., 2012. Fra 25-års alder reduseres utholdenhet og muskelstyrke med 10% per 10 år dersom individet er inaktiv (Heath et al., 1981; Wilmore, 1991. Systematisk utholdenhets- og styrketrening ser derimot ut til å redusere tapet med inntil halvparten, det vil si en reduksjon tilsvarende 5% per 10 år hos fysisk aktive individer (Heath et al., 1981. Eldre individer ser ut til å ha de samme treningsinduserte effekter som yngre, det vil si at man får effekt av økt aktivitet uansett alder, og da også lik prosentvis fremgang (Hagberg et al., 1989. Studier har vist at det er mulig å øke maksimalt oksygenopptak og maksimal muskelstyrke med inntil 10-20% i løpet av en 12 ukers intervensjon (Hagberg et al., 1989; Reeves et al., 2003; Lohne-Seiler et al, in press. Da muskelstyrke ser ut til å ha en sterk sammenheng med individets funksjonsevne/mobilitet, er det viktig å kunne tilrettelegge for systematisk styrketrening for eldre for på den måten å oppnå

    Skötseln av ungskogar är viktig för skogsbeståndens utveckling i produktionen av förädlingsbart stockvirke, ändå försummas skötselarbetet av ungskogarna på manga håll i Finland. Riksskogstaxeringarna visar att behovet av plantskogsskötsel stiger på Kustens område, men den utförda arealen har hållits konstant. Lagen om finansiering av hållbart skogsbruk (Kemera) uppkom 1996 för att uppmuntra privata skogsägare i skötseln av kostsamma plantskogar. Idag förekommer det mycket problem med Kem...

    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.

    2014-10-01

    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.

  14. Toward robust AV conferencing on next-generation networks

    Science.gov (United States)

    Liu, Haining; Cheng, Liang; El Zarki, Magda

    2005-01-01

    In order to enable a truly pervasive computing environment, next generation networks (including B3G and 4G) will merge the broadband wireless and wireline networking infrastructure. However, due to the tremendous complexity in administration and the unreliability of the wireless channel, provision of hard-guarantees for services on such networks will not happen in the foreseeable future. This consequently makes it particularly challenging to offer viable AV conferencing services due to their stringent synchronization, delay and data fidelity requirements. We propose in this paper a robust application-level solution for wireless mobile AV conferencing on B3G/4G networks. Expecting no special treatment from the network, we apply a novel adaptive delay and synchronization control mechanism to maintain the synchronization and reduce the latency as much as possible. We also employ a robust video coding technique that has better error-resilience capability. We investigate the performance of the proposed solution through simulations using a three-state hidden Markov chain as the generic end-to-end transport channel model. The results show that our scheme yields tight synchronization performance, relatively low end-to-end latency and satisfactory presentation quality. The scheme successfully provides a fairly robust AV conferencing service.

    I 2002 startet IASB og FASB et prosjekt med formål å etablere et felles internasjonalt regnskapsspråk. IFRS 15 Revenue from Contracts with Customers er del av dette harmoniseringsprosjektet. Standarden presenterer et omfangsrikt regelsett for regnskapsmessig behandling av inntekt fra kundekontrakter. Nåværende inntektsstandarder innen IFRS er kritisert for ikke å gi tilstrekkelig informasjon om innregning av inntekt. En konsekvens av dette er at like transaksjoner er ført på ulike måter. Regn...

  20. Development of a Serological Assay for the Sea Lion (Zalophus californianus) Anellovirus, ZcAV.

    Fahsbender, Elizabeth; Rosario, Karyna; Cannon, John P; Gulland, Frances; Dishaw, Larry J; Breitbart, Mya

    2015-01-01

    New diseases in marine animals are emerging at an increasing rate, yet methodological limitations hinder characterization of viral infections. Viral metagenomics is an effective method for identifying novel viruses in diseased animals; however, determining virus pathogenesis remains a challenge. A novel anellovirus (Zalophus californianus anellovirus, ZcAV) was recently reported in the lungs of captive California sea lions involved in a mortality event. ZcAV was not detected by PCR in the blood of these animals, creating the inability to assess the prevalence of ZcAV in live sea lions. This study developed an enzyme-linked immunosorbent assay (ELISA) to detect antibodies to ZcAV in sea lion serum. To assess ZcAV prevalence, paired serum and lung samples (n = 96) from wild sea lions that stranded along the California coast were tested through ELISA and PCR, respectively. Over 50% of the samples tested positive for ZcAV by ELISA (34%), PCR (29%), or both (11%) assays. ZcAV is prevalent in stranded wild sea lion populations and results suggest that PCR assays alone may grossly underestimate ZcAV exposure. This ELISA provides a tool for testing live sea lions for ZcAV exposure and is valuable for subsequent studies evaluating the potential pathogenicity of this anellovirus.

    2010-01-01

    This paper introduces QOperAv v1.5, a Java application available for free. (Source code included in the distribution.) QOperAv is a "code generator" for generating quantum circuits. The quantum circuits generated by QOperAv can be used to evaluate with polynomial efficiency the average of $f(A)$ for some simple (that is, computable with polynomial efficiency) function $f$ and a Hermitian operator $A$, provided that we know how to compile $\\exp(iA)$ with polynomial efficiency. QOperAv implements an algorithm described in earlier papers, that combines various standard techniques such as quantum phase estimation and quantum multiplexors.

  4. STUDY ON EFFICIENT COMPUTATION AND PERFORMANCE OF AV-BASED REDUCED-RANK FILTERING

    Institute of Scientific and Technical Information of China (English)

    Xu Bin; Yang Chenyang; Mao Shiyi

    2005-01-01

    In this paper, the complexity and performance of the Auxiliary Vector (AV) based reduced-rank filtering are addressed. The AV filters presented in the previous papers have the general form of the sum of the signature vector of the desired signal and a set of weighted AVs,which can be classified as three categories according to the orthogonality of their AVs and the optimality of the weight coefficients of the AVs. The AV filter with orthogonal AVs and optimal weight coefficients has the best performance, but requires considerable computational complexity and suffers from the numerical unstable operation. In order to reduce its computational load while keeping the superior performance, several low complexity algorithms are proposed to efficiently calculate the AVs and their weight coefficients. The diagonal loading technique is also introduced to solve the numerical unstability problem without complexity increase. The performance of the three types of AV filters is also compared through their application to Direct Sequence Code Division Multiple Access (DS-CDM A) systems for interference suppression.

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. Blant monozygote (MZ tvillingpar gjenspeiler fødselsvektforskjeller innenfor tvillingparetintra-uterine miljøforskjeller. Blant dizygote (DZ par kan vektforskjellen være både genetiske ogmiljøbetinget. Ved sammenligning av fødselsvektforskjeller innenfor tvillingparene er tvillingen som ikkehar gjentatte øreinfeksjoner en matchet kontroll blant OM diskordante par. Resultatene antyder at lavfødselsvekt er en risikofaktor for otitis media. Gjennomsnittlig vektforskjell blant par diskordante for OMvar 48 gram, og den av tvillingen som ikke rapporterte OM hadde signifikant høyere fødselsvekt.Kværner KJ, Tambs K, Harris J, Magnus P. Do pregnancy-related factors influence the development ofotitis media? Nor J Epidemiol 1997; 7 (1: 55-58.  ENGLISH SUMMARYThe association between intrauterine growth, as measured by weight and gestational age, and the occurrenceof recurrent ear infections was studied using data from a population based sample of 7992 Norwegian twins.Perinatal measures were collected from the Medical Birth Registry, and reports of recurrent ear infectionswere based on

    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.

Immobilization of BCNU on a nanocarrier might increase the thermal stability of BCNU and extend its half-life.Methods: Nanosized graphene oxide (GO could be modified by polyacrylic acid (PAA to improve the aqueous solubility and increase the cell penetration efficacy of the nanocarrier. PAA–GO intended as a drug carrier for BCNU was prepared and characterized in this study. The size and thickness of PAA–GO was investigated by transmission electron microscopy and atomic force microscopy, and the presence of PAA functional groups was confirmed by electron spectroscopy for chemical analysis and thermogravimetric analysis. BCNU was conjugated to PAA–GO by covalent binding for specific killing of cancer cells, which could also enhance the thermal stability of the drug.Results: Single layer PAA–GO (about 1.9 nm with a lateral width as small as 36 nm was successfully prepared. The optimum drug immobilization condition was by reacting 0.5 mg PAA–GO with 0.4 mg BCNU, and the drug-loading capacity and residual drug activity were 198 µg BCNU/mg PAA–GO and 70%, respectively. This nanocarrier significantly prolonged the half-life of bound BCNU from 19 to 43 hours compared with free drug and showed efficient intracellular

    Bakgrunn: Orthorexia nervosa ble for første gang omtalt som en ny spiseforstyrrelse av Dr.Bratman i 1997 (3). Til forskjell fra den beslektede lidelsen anorexia nervosa er ikke orthorektikeren sykelig opptatt av å gå ned i vekt, men av å spise sunt og oppnå en positiv livstilstand gjennom maten. Orthorexi i seg selv truer ikke den fysiske helsen slik som anoreksi, men kan potensielt utvikle seg til en mer alvorlig tilstand i ekstreme tilfeller. Det foreligger per i dag ingen offisielle retnin...

    Full Text Available A new composite poly(caprolactone (PCL and poly(acrylic acid (PAA (PCL:PAA 1:5 scaffold was synthesized via dispersion of PCL particles into a PAA network. Silica microspheres (Si (2–12 μm were then prepared by a lyophilized micro-emulsion/sol-gel (Emugel system using varying weight ratios. The model drug ciprofloxacin (CFX was used for in situ incorporation into the scaffold. The physicochemical and thermal integrity, morphology and porosity of the system was analyzed by X-Ray Diffraction (XRD, Attenuated Total Refelctance Fourier Transform Infrared (ATR-FTIR, Differential Scanning Calorimetry (DSC, SEM, surface area analysis and liquid displacement, respectively. The mechanical properties of the scaffold were measured by textural analysis and in vitro bioactivity, biodegradation and pH variations were evaluated by XRD, FTIR and SEM after immersion in Simulated Body Fluid (SBF. The in vitro and in vivo studies of the prepared scaffold were considered as future aspects for this study. CFX release was determined in phosphate buffer saline (PBS (pH 7.4; 37 °C. The incorporation of the Si microspheres and CFX into the scaffold was confirmed by XRD, FTIR, DSC and SEM, and the scaffold microstructure was dependent on the concentration of Si microspheres and the presence of CFX. The system displayed enhanced mechanical properties (4.5–14.73 MPa, in vitro bioactivity, biodegradation and controlled CFX release. Therefore, the PCL/PAA scaffolds loaded with Si microspheres and CFX with a porosity of up to 87% may be promising for bone tissue engineering.

    Phased-array antenna (PAA) technology plays a significant role in modern day radar and communication networks. Truetime- delay (TTD) enabled beam steering networks provide several advantages over their electronic counterparts, including squint-free beam steering, low RF loss, immunity to electromagnetic interference (EMI), and large bandwidth control of PAAs. Chip-scale and integrated TTD modules promise a miniaturized, light-weight system; however, the modules are still rigid and they require complex packaging solutions. Moreover, the total achievable time delay is still restricted by the wafer size. In this work, we propose a light-weight and large-area, true-time-delay beamforming network that can be fabricated on light-weight and flexible/rigid surfaces utilizing low-cost "printing" techniques. In order to prove the feasibility of the approach, a 2-bit thermo-optic polymer TTD network is developed using a combination of imprinting and ink-jet printing. RF beam steering of a 1×4 X-band PAA up to 60° is demonstrated. The development of such active components on large area, light-weight, and low-cost substrates promises significant improvement in size, weight, and power (SWaP) requirements over the state-of-the-art.

    Staphylococcus aureus is the causative agent of many diseases, including meningitis, bacteraemia, pneumonia, food poisoning and toxic shock syndrome. Structural characterization of the PaaI-like thioesterase SAV0944 (SaPaaI) from S. aureus subsp. aureus Mu50 will aid in understanding its potential as a new therapeutic target by knowledge of its molecular details and cellular functions. Here, the recombinant expression, purification and crystallization of SaPaaI thioesterase from S. aureus are reported. This protein initially crystallized with the ligand coenzyme A using the hanging-drop vapour-diffusion technique with condition No. 40 of Crystal Screen from Hampton Research at 296 K. Optimal final conditions consisting of 24% PEG 4000, 100 mM sodium citrate pH 6.5, 12% 2-propanol gave single diffraction-quality crystals. These crystals diffracted to beyond 2 Å resolution at the Australian Synchrotron and belonged to space group P12(1)1, with unit-cell parameters a = 44.05, b = 89.05, c = 60.74 Å, β = 100.5°. Initial structure determination and refinement gave an R factor and R(free) of 17.3 and 22.0%, respectively, confirming a positive solution in obtaining phases using molecular replacement.

    The overall purpose of the project was to make a survey of the changes in the Swedish nuclear power plants over the last five years. There is a risk that nuclear power companies after a deregulation will focus especially on reducing operation and maintenance costs and that the changes could have a negative effect on the reactor safety. The task has involved summarising the actual changes, describing the present situation, the need for future development and the differences between the plants as well as identifying possible reactor safety related risks. The survey has been carried out in a broad perspective, studying the changes in equipment, maintenance strategies and the work situation of the staff. Three case studies were carried out at the Swedish nuclear power plants. Documentation from the companies has been analysed and a selection of in total 27 'informed' employees in different positions have been interviewed in total. The project also included a fourth case study concerning railway traffic. This branch of business is interesting because of its longer experience on a deregulated and competitive market. Conclusions concerning the companies individually as well as similarities and differences between them are presented in this report. Results: There have been more changes both in strategy and organisation in the last five years than during the preceding 5-10-year-period and the pace has been relatively rapid. The deregulation of the electricity market was implemented January 1997 and became the main motive force for the changes. The staffing has been reduced or unchanged and the work demands have increased. The maintenance skills have been redistributed within the organisation. New methods and equipment, i.e. RCM, and programmable systems make increased demands for analytical and theoretical competence. In the short term, job satisfaction and motivation have in some cases been negatively influenced by the new organisation forms, according to several of the interviewed. The results indicate, in accordance with other research results, that rationalisations and changes must be combined with work development and the participation of the employees to be successful. Outsourcing has been used for some activities. All the companies have established a joint maintenance department for their units. The companies have been moving towards lean organization which has increased the work load of the staff. Therefore more planning is required to get a optimal resource allocation, to avoid problems at work peaks. All the plants have abandoned a downright customer-supplier relation for the benefit of one competent maintenance supplier with a comprehensive view. As a result the contractual undertaking of the maintenance department towards the production units is made on a long term basis. The new maintenance strategy is based on status controls for condition based maintenance and on riskbased analysing methods. There are modern computer-based maintenance systems at all the plants. Computer-based instruments are used direct in the production line where they require a competence shift in the staff. Positive effects that appeared in the interviews are better possibilities for experience feed back and methods development, access to a wider and larger competence and a joint working method. The results show that there are already some positive effects and there are more to be expected. But it is also clear that these effects have neither come as easily nor as fast as was expected. Possible negative effects: there is a risk that the staffing might be too scarce, especially in work peaks, e.g. unexpected shutdowns. A high work load and much overtime work mean greater strain on the staff. Problems with job satisfaction and motivation, chiefly after the change to a matrix organisation. Uncertainties as to responsibility and roles in the new organisation. The practical competence might 'disappear' in the present competence shift focusing on analytical, computer based methods. The difficulties of risk based methods are several: they might not correspond with reality, they might not measure what they are intended to measure and it might be that the probabilistic risk assessment approach is allowed to dominate over the deterministic at the expense of a good balance between them. There is also a risk that the methods are not enough developed, that the knowledge of how the results should be interpreted is limited and that this might lead to the wrong conclusions. With tighter priorities there is an increasing risk that the wrong things are left out. The feeling of 'ownership' towards a certain production unit as well as the team feeling might disappear when the employees work on several units. Deficiencies in the maintenance instructions become evident when the staff are transferred. If the work routines have not been thoroughly documented there is a risk that the staff make mistakes or that the measures are forgotten. A number of conditions have been identified that might influenced the reactor safety negatively in the long term if they are not taken care of. Such conditions are an increased pressure on the staff, high work load and too much overtime, uncertainties as to responsibility and roles, lack of job satisfaction and motivation and deficient maintenance instructions. Economic pressure and a high rate of change might also give negative influence. It is, however, important to stress that the results indicate that the changes are not carried out with a one-sided focus on cost reductions but with a focus on both individual and organisational learning and development. Safety culture has also been an important part of the change operations. It seems, though, as if it has been more difficult to balance the economy and safety messages to the staff.

    Today carries approximately 23,000 flights over 2.2 billion passengers annually. On a global basis air travel accounts for almost 2 to 2.5 percent of the total anthropogenic Co2 emissions. Domestic civil aviation in Norway emitted 1.05 million tonnes of Co2 in 2008, according to reporting to the United Nations Framework Convention on Climate Change (UNFCCC, 2011). Emissions from international aviation from Norwegian airports in 2008 was just under 1.2 million tonnes of Co2 (National Inventory Report, 2010). Aviation is a sector that has been growing: in Norway the emissions from domestic aviation increased by 55 percent from 1990 to 2008, and also globally emissions have increased. There has been an even more powerful increase in traffic, but this increase did not been steady: The development is closely linked to the economy and the reduction is observed in periods of economic downturn. New technology and streamlining flight patterns made aircraft more energy efficient, which has helped to reduce emissions, but it has not been enough to compensate for the strong growth in traffic. If this trend continues, the total emissions from aviation increase further. In addition to Co2 consists emissions from airplanes a variety of other components that affect the climate, either directly or indirectly through chemical and physical processes in the atmosphere. This is not unique to aviation, but also apply to other sectors. The impact is complex and complicated, some mechanisms provide a cooling, others warming. Some effects are regional and have a geographic (and per day) variation in radiative forcing. Regional heterogeneous forcing can potentially change temperature and pressure distribution in the atmosphere and hence circulation patterns. The various emissions also have very different lifetimes in the atmosphere and affects the climate of the different time scales. For a number of mechanisms providing climate change are the chemical and meteorological conditions in the atmosphere essential. Changes in those areas or heights planes operates, may thus lead to changes in climate.(eb)

    Within this project studies have been carried out how an active choice of refractory and/or addition of support burners can improve the combustion process in solid fuel boilers. The test rig, that was erected in the previous project at Energitekniskt Centrum in Piteaa, was modified with a moving grate and also equipped with a thermo camera for supervision of the drying- and combustion process. The test rig had the following features and equipment: A fuel bin containing wood fuel with a moisture content of 42%; Possible load range between 40 kW up to 160 kW fuel effect; Continuous feeding of the fuel on the grate with a total cycle time of 30 minutes; Zone divided inlets for the primary air to the grate; No secondary combustion air inlets; Exchangeable ceramic roof segments for testing, electrical heated; A support burner either directed towards the fuel bed or towards the ceramic roof; Analysis of CO, O{sub 2} and CO{sub 2} in the exhaust gases; A thermo camera monitoring the grate. Four different types of ceramic brickworks have been tested with different qualities of heat conductivity, emissivity, heating capacity and reflexion of IR-radiation. Aluminium oxide is an extreme good isolating brickwork with low heating conductivity. Silicone carbide (SiC) has high conductivity and emissivity and is also available to a higher price. SiC is also more resistant to chemical reactive gases. A test program has been performed with different loads for the test rig. Same air to fuel ratio has been used for the different refractory material tests. The absolute emissions from the test rig where not optimised since the aim with the test rig was to compare the different ceramics. For example the test rig has no secondary air inlets. A correlation between CO-emission and fuel bed temperature in the drying zone is shown in the report. Andalusite has the lowest CO emission at low load and SiC the lowest emission at higher fuel input. The thermo camera for supervision of the combustion process seems to be an excellent tool. Support burner placed just over the fuel bed (bed burner) has little influence of the temperature of the brickwork. When the burner is closed the temperature decreases relatively fast when new wet fuel is feeded into the rig. Burner close to the brickwork is warming up both the ceramic and the fuel bed. The combination with SiC gives a fast heating up and also large energy storage. When it comes to transient load processes SiC is, at the same time, rapidly cooled down but is also warming up the fuel bed the longest period after stopped fuel feeding. This is, of course, an advantage if, for example, the fuel moisture content changes. Further R and D in the area with deeper understanding of appropriate brickworks for different fuel types are suggested in the rig. The use of thermo camera can also be developed in an interesting way.

    The present report aims at demonstrating how an evaluation can be performed of the effects of local wood combustion on the air quality in a community. One of the important conclusions of the BHM programme is that the air quality norms are not fulfilled regarding PM10 in residential areas where old wood stoves, without, or with too small hot water accumulator tanks are in use. This report reviews procedures for mapping the emissions, and describes the measurements necessary for comparing emissions to the norms.

The requirement that consequence analyses should be worked out for each oil field is a part of today`s environmental management of the petroleum activities. The report aims to find out how the consequence analyses, the executive work and the decision processes work with respect to general criteria for public means, and to lay the foundation of a new system that includes regional consequence analyses. The report summarises the main results for the development of Haltenbanken, then discusses some issues of consequence evaluations as environmental means and finally deals with improvements of the present system. 51 refs., 2 figs., 7 tabs.

  9. The concentration of heavy metals and PAH's in soot water - suggested methods of treatment; Halten av tungmetaller och PAH:er i sotvatten - foerslag paa behandlingsmetoder

    What we here call 'soot water' is a contaminated water from seasonal cleaning of the furnace and heating sections with water. Earlier, it was common to discharge this type of water directly to a recipient or to the municipal sewage plant. Today, with new, more restricted regulations, this is not accepted unless the concentrations of different substances is well documented and below official limits. The objective of this project has been to increase the knowledge of soot water from different types of combustion plants and suggest ways to handle/treat this water. The project started with a literature survey of soot water in the Swedish, English and German open literature. The next step was to perform analyses on soot water from combustion of waste, wood chips, wood chips/peat, bio oil and heavy fuel oil. It is very difficult to take a representative sample of soot water. It is especially the amount of particles in the water that may change. Since particles contains high levels of heavy metals, this may severely affect the concentrations of metals in the sample, if included in the analysis. Soot water contains very low concentrations of mercury. The concentrations of PAH is also close to or below the detection limit. On the other hand, all soot water analysed, contains enough concentrations of some metal, to make it unsuitable to be discharged directly to a recipient or drain. Four methods of water treatment have been examined for its capacity to treat soot water with regard to their capacity, operational and economical performance. The result is as follows: Chemical precipitation is the method that is judged to have the highest potential as long as the chlorides and sulphates can be discharged to the recipient or municipal waste plant. Reversed osmosis is judged less suitable for soot water since the water contains calcium, sulfates and carbonates that may clog the membranes. Evaporators is also judged to be of less interest for soot water due to its content of chlorides which will lead to expensive materials and due to its content of calcium and sulfates that may give scaling on heat transfer surfaces. Ion exchange resins can be of some interest for waters that are generally clean, but have one metal with to high concentration. In the report, the use of soot water for cooling of slag, moistening of the fuel, reuse as soot water and cleaning in an existing water treatment plant, have also been discussed. This project have generated a lot of new information about soot water and what soot water contains. Information that is important when discussing its effect on the environment as well as looking for ways to treat the water. The project has also shown the importance of correct sampling and analysis of soot water and discussed ways to treat this water. Information that is requested by personnel on combustion plant, authorities and by companies building treatment plants

    This report provides an insight into what may be the consequences for Sweden's food supply if the ability to import sufficient quantities of fossil energy decreases. The situation described is an imaginary situation that arose quickly and unexpectedly by political unrest or natural disaster. There has thus been no preparation for the situation. The length of the crisis is set to a period of 3-5 years. During that time, there is assumed no technological development or other structural change, that will change conditions compared to the current situation. If the crisis becomes more prolonged it will however gradually force major changes. Today's food supply in Sweden and much of the world depends on a constant supply of fossil energy. In the production of food is used, for example, large amounts of diesel, heating oil and mineral fertilizers. This applies to primary production of vegetables and animal breeding but also to a high degree of for user-industries , which ensures that the raw materials become finished food products for consumers. Between the different stages there are transport's in many directions that depend on fossil energy. Three different scenarios are termed low deprivation, lack of resources and high deprivation. They represent different failure scenarios where the availability of fossil energy is assumed to decrease. The three levels are tentatively set as a decrease of 25%, 50% and 75% compared with current levels. These percentages are set as initial discussion-levels from which calculations have been made of how the different stages of production will be affected.

    The goal of the transport policy is that every citizen shall have a transport service on a reasonable level. In sparsely populated areas the public transport service is on a low level and many groups without a private car will have small possibilities to travel to different activities. Siljansnaes, with nearly 2000 citizens, is a small region in the community Leksand in Dalarna where the transport problem have been more tangible. The aim of this project has been to create a transport system more based on the needs and requirements. Also the people who lives in Siljansnaes in their leisure times are a part in the project. They are almost as many as the permanent living ones. The result also has been built on the goal of a higher care of the environment. The transport solution contains; village-bus, car-pooling, changed price system for public transport, but also a partnership between the citizens, the community and the regional transport company (Dalatrafik). The project as a process has the goal that the people in Siljansnaes should take part of the solution and the responsibility for the operation of the system.

    Det Norske Veritas Nuclear Technology has performed a literature study of dynamic load on a BWR (Boiling Water Reactor) internals caused by a large pipe break. The goal of the study was to improve the knowledge about the physics of phenomena occurring in the RPV (Reactor Pressure Vessel) after pipe break in the main circulation system and also to make a review of calculation methods, models and computer programs including their capabilities when calculating the dynamic loads. The report presents description of relevant parts of a BWR, initial and boundary conditions, and phenomena determining the loads - rapid depressurization and propagation of pressure wave (including none-equilibrium). Furthermore, the report generally describes possible methodologies for calculating the dynamic loads on internals after the pipe break and the experiences from calculations the dynamic loads with different methods (computer programs) including comparisons with experimental data. Fluid-Structure Interaction methodology and its importance for calculation of dynamic loads on reactor internals is discussed based on experimental data. A very intensive research program for studying and calculating the dynamic loads on internals after pipe breaks has been performed in USA and Germany during the seventies and the eighties. Several computer programs have been developed and a number of large-scale experiments have been performed to calibrate the calculation methods. In spite of the fact that all experiments were performed for PWR several experiences should be valid also for BWR. These experiences, connected mainly to capabilities of computer programs calculating dynamic loads, are discussed in the report.

    During the early phase of commercialisation of willow short rotation forestry in Sweden it was considered to be important to cut down the shoots after the establishment year, and this practice still is maintained today. Several reasons then were put forward for cutting down. The primary goal was to stimulate sprouting of more shoots, thereby obtaining a rapidly closing stand which could compete with weeds. Another reason was that it would enable weed control during the second year. In some of the older clones, which exhibited bow-shaped shoots, cutting down was supposed to lead to more straight growing shoots which rendered less biomass loss at harvest. In the meantime, the practice of cutting down has been abandoned in Denmark, and there are reasons to scrutinise the effects of cutting down on available biomass production figures from Swedish field trials. The main goal with this project was to try to quantify the effects of cutting down on the biomass productivity of willow during the first and later cutting cycles. Thus far, efforts in this research topic have not led to a scientifically documented quantification on the effects, and therefore a scientific basis for hands-on recommendations to willow growers is lacking. The purpose of our work consequently was to generate practical recommendations with regard to the management measure of cutting down, and the audience targeted consisted of willow growers (farmers, land-owners and entrepreneurs) who are deciding about and perform the actual management of willow stands to obtain higher yields. This information also is of large relevance for all extension workers in willow growing. Data have been collected from a field trial which was planted in Flosta, Enkoeping, in 2005. As this was the only experiment on cutting down which ran during the project period, we searched the archives which contained material from another experiment which ran from 1992 to 1996 in Ultuna, Uppsala, and from which some date were collected as late as in 2000. Furthermore, the archives contained data from an experiment at the Brunnby experimental farm in Vaesteraas, which ran from 1991 to 1994. Very few papers on cutting down as a management measure were found in peer-reviewed articles, while foreign manuals for willow growers usually referred to the recommendations as described in the Swedish manuals. Results from the three field trials in Sweden, which were established with the aim to quantify the effects of cutting down of willow shoots after one year on subsequent biomass production, show that no positive effects of cutting down on yield have occurred at all. In contrary, the results altogether show that cutting down has an adverse effect on subsequent biomass production in willow during the first cutting cycle, and that cutting down also may cause a lower productivity during later cutting cycles. We conclude that cutting down, apart from being a costly management measure, leads to production losses in willow cultivation. We recommend that cutting down should not be used as a routine measure after the establishment season. This recommendation contradicts the current recommendation which currently is advocated in Sweden. By means of extension work, current practice should be changed to obtain higher biomass yields and better profit in willow short rotation forests

    The municipalities are responsible for taking care of food waste from households, commercial kitchens and restaurants. So there is ample supply of waste that municipalities can produce biogas, but the path is not easy. In this report we highlight some good examples of municipalities that have come a long way in terms of collecting food waste for anaerobic digestion to produce biogas. The idea is that you will be inspired by these examples and perhaps find new ideas and approaches on how more of the food waste could be biogas and biofertilizer in your community

    The aim of this thesis is to analyse how space heating for single-family houses, and energy system conversion has been constructed and discussed at national, municipal and household levels. Political documents have been studied, and interviews have been carried out with politicians, civil servants and householders in the municipality of Falun. In order to study and analyse similarities and differences between these three political levels, the following main questions were asked: In which sense is the use of electrical heating formulated as problematic? How are the causes of these problems presented, and which solutions are suggested? What are the effects of how problems, causes and solutions are constructed? At the national level, the use of electricity produced by nuclear power was considered a problem. Initially the municipality's policy documents present the same problem, but there is a change of focus to the problem of imported electricity produced by fossil fuel, and the resulting emissions. At household level, the problem was often an old and badly functioning space-heating system. But some households did not formulate a problem before they converted. Instead they were influenced by their neighbours and thereby convinced. At all three political levels, there is consensus on the households' responsibility concerning energy transition. While industry tends to be considered incapable of cutting down its energy consumption, households are expected to take the responsibility seriously. Furthermore, within the household, the heating system tends to be constructed as a predominantly male concern. At all three levels, households are perceived as dependant on economical subsidies when taking the decision to convert from electrical heating. Although it is interesting that the interviewed householders only apply this view to others than themselves. They are convinced that other households need subsidies to act in an environmentally correct way. The discourse concerning the Swedish energy transition illustrates a shift away from a definition of ecological modernisation where environmental considerations influence economic development. The thesis clearly shows how economic arguments repeatedly influence environmental concerns. However, the tension between the two is played down and concealed through the lack of problemisation of the responsibility of industry, and through the focus on the need for education and future opportunities. Political dialogues concerning the use of electrical heating and the conversion of energy systems towards more renewable energies are dominated by economic arguments at the three levels. One effect of this is an assumption that energy policy instruments such as information and economic subsidies are essential for the energy transition. However, if householders rather are influenced by their neighbours should the government use economic subsidy as the main energy policy instrument

    The Wind Power Handbook is designed to make it easier for municipalities and wind energy companies to plan wind power projects. It contains the issues to be considered when planning and review, both the legal bases under essentially Planning and Building Act and the Environmental Code and the environmental assessments. The manual is primarily addressed to the municipalities and various operators. There are many interests to be met at a wind power establishment, which requires knowledge and cooperation of the different actors on the planning and approval process to be effective. Here we have gathered important knowledge base to facilitate the process and to contribute to a balanced decision

    Domestic combustion of solid fuels is, besides traffic and industry, a major source to particles in the air. Increased biomass combustion means a risk of contributing to high concentrations of particles with respect to the environmental goals. Particles are a health risk. The number of ultrafines and the content of the particles are considered crucial for the effects. Gradually, new solid biofuels with high ash content and different ash composition are used. This means an enhanced risk of high particle emission and a change in the formation of particles. The aim of the project is to contribute to the description of the mechanisms for formation of particles at combustion of biomass with high content of ash. The possibility to decrease the particle emission by the use of additives will be especially investigated. Thereby, problems with particle emissions, as well as formation of deposits may be minimized. The project contains two parts. The first one is about combustion of oat grain, and has already been reported. In this report the second part of the project is presented. Reed canary grass and straw were studied. To decrease the particle emission from combustion of straw, tests with straw and the additive kaolin (clay mineral) were also carried out. The fuels were pelletized and contained 4-5 % ash (dry fuel). Reed canary grass (perennial grass) was chosen because it is has potential and it has also been much studied in Sweden. Straw was chosen because it has high accessibility, and is already fired to a certain degree. Straw contained 2.6 times more chlorine than reed canary grass. Reed canary grass had Si as dominating ash element (79 %), and thereafter it contained K (6 %), Ca (6 %) and P (3 %). A good half of the straw ash contained Si and thereafter K (23 %) and Ca (15 %) were most abundant. The fuels were continuously fired in a multi-stoker from Sonnys Maskiner, connected to a boiler from Centrometal. The particles mass concentration was measured by sampling on filter, and the mass size distribution with a low pressure impactor (LPI). The foil samples from the LPI were chemically analysed. The number concentration and size distribution were measured with an electrical LPI. Combustion of reed canary grass led to the lowest concentrations of particles, both with respect to mass, 12 mg/MJ, and number, 8.2 x 1012/MJ. Mass concentration at straw combustion was 64 mg/MJ, and the number concentration was 14 x 1012/MJ. The case of 3 % kaolin mixed with the straw pellets gave a decrease of the mass concentration, but simultaneously the emission almost doubled with respect to number of particles. However, in the case straw and 6 % kaolin the mass concentration of particles increased, while about the same number concentration as in the other additive case was noted. The following conclusions are drawn from this work: - Pellets from reed canary grass were good to fire in the multi-stoker used. However, the effects of ash in the long-range needs to be further investigated. - It is, because of slagging, not recommended to fire straw pellets in the stoker. - Combustion of straw pellets and the additive kaolin works fine in the stoker. - Combustion of reed canary grass gave very low emission of particles (mass). Mainly fine (< 1mum) particles, dominated by potassium sulphate, were emitted. - Combustion of straw gave much higher emission of particles than combustion of reed canary grass. The particles were mainly fine and dominated by KCl. - The number concentration of particles was almost twice as high at combustion of straw as it was at combustion of reed canary grass. Fine particles dominated. - High content of ash in the fuel combined with high content of chlorine and potassium means a risk of high particle emission. - There is a potential of decreasing the emission of particles by adding kaolin to straw fuel. However, there is a risk of overdosing and thus enhance the emission

    City Cooperation on the South West Coast, 'Implementing Energy and Environment' has been a short-term project that has spanned from June 2010 to December 2011, with a operational phase of the last six months. Objectives and activities were developed in a collaboration between Stavanger, Business Region Bergen and Kristiansand Municipality. The project intended to provide support for and knowledge of an overall renewable energy industry in southwestern Norway. This evaluation is based on a assessment of whether the objectives and activities outlined in the project description is followed up. This is supplemented with assessments of implementation and benefits for the sector. In general, the activities carried out as described in the project proposal.Through surveys and interviews, activities and positive initiative feedback, but also constructive suggestions that can be helpful for learning the regional funding programs. Study and delegation travel, which formed majority of the activity, is seen as a broad measure that can embrace many. The benefit, however, depends on site added to venues that are of interest to the industry. Journeys are important meeting places for establish or maintain contact with regional and international partners. InBesides networking helps such forums to increase knowledge of the sector, either for specific technological and product knowledge or general knowledge about the industry. This means that this type of travel is useful both for the industry, research communities, developers, funding agencies and policy makers to support the industry. Nevertheless, it is worth noting that some interviewees emphasized that the delegation traveling to those who were carried to Boston Amsterdam should be a main focus of the participants related industry.The major barriers to large cities and industry in their efforts to facilitate for developing a strong renewable sector in southwestern Norway emphasized to be The major barriers to large cities and industry in their efforts to facilitate for developing a strong renewable sector in southwestern Norway emphasized to be associated with national energy policy. Industry players and industry developers experiencing a loss of interest in the field, which affects the development prospects in Norway. New discoveries in the North Sea combined with adequate access to renewable energy, making it difficult to succeed in its arguments about the development of offshore wind. It is stated by some politicians that Norway is not dependent of this renewable energy source. As a result of the policy interest is reduced, the basis to obtain national investors limited. In addition, the industry is experiencing one expertise escape in a time where high activity in the oil industry require the same competence renewable sector. The consequence is that suppliers to the international renewable industry must work individually directly to the relevant market. Regional coordination seems to depend on a common political priorities linked to a domestic market where products can be tested and developed. Until this may be in place, ability largely to assist the industry in its internationalization. In this way the project 'Implementing Energy and Environment' helped both to create arenas and opportunities for knowledge and learning for both players in renewable sector and commercial developers in the region. In connection with development opportunities for cooperation in renewable energy industry between Bergen, Stavanger and Kristiansand we will conclude by returning to the 'engine role' which was widely discussed in the City Project Innovation 2010. Experiences from the project 'Implementing Energy and Environment' appears relevant. First, the three cities continue to make important contributions when it comes to giving industry support and incentives to develop networks regionally and internationally. In the context, quality and relevance to the industry particularly important for the further work with the delegation traveling, either in each city or

    In Sweden, the Swedish Forest Agency recommend ash recycling after whole-tree harvest (WTH), i.e. the whole tree above the stump is harvested. If this recommendation is complied, ash recycling will become a quite extensive forestry practice. To gain more knowledge regarding effects of ash on tree growth, storage of carbon (C) and nitrogen (N) in the upper soil, and soil-water chemistry, two field experiments were established. The experimental design was a randomized block design. Both experiments were installed on quite fertile sites in southern Sweden. On fertile sites (C/N less than 30), ash addition is hypothesized to increase tree growth, reduce the storage of C and N in the upper soil, and increase the concentrations of nitrate in soil water. One experiment (291 Guvarp) was established on a recently harvested clear cut. The sample plots were soil scarified by disc trenching and planted with Norway spruce (Picea abies L. Karst.) seedlings. Seedling height was measured at planting, and, two months later, seedling survival and height growth in 2011 was recorded. The other experiment (290 Bala) was located to a Norway spruce stand that was thinned by WTH. The initial registration and sampling comprised stand data and sampling of the upper soil (FH-layer). In addition, suction cups were installed at 50 cm depth for sampling of soil water. The experiments were designed for long-term monitoring, comprising several decades. For most of the variables registered, data did not show any significant differences among means for the plots representing different treatments. Pre-treatment data for individual plots showed acceptable comparability among plots within the blocks, which is a good starting point for detecting future changes caused by the treatments

    In early thinnings where either pulpwood or energy wood is harvested, the same logging machines are generally used for both products. The choice between pulpwood or energy wood is therefore mostly dependent on the harvestable volumes of the two assortments and the price difference. During the years 2009-2010 follow up studies on machine performance in early thinnings were performed in the coastal region of Vaesterbotten. The purpose was to study the time consumption, production and costs for harvesting of energy wood and pulpwood, either in separate operations or through integrated harvest of both assortments. In total 43 different harvesting objects were included in the study of which 34 were early thinning stands and 9 were harvesting of e.g. road sides and overgrown arable land. During the year 2010 the follow up studies were complemented with time studies of three of the machine systems; three harvester and forwarder systems and a small harwarder system were studied. In the follow up study, a total of 16179 m3solid energy wood and 1906 m3solid on bark pulpwood were harvested from an area of 295 ha. In the thinning stands the average harvested stem size was 25 dm3solid and on average 49 m3solid biomass per ha of energy wood. In 9 of these stands an integrated harvest of pulpwood and energy wood was performed. The average stem size of the removed stems was 36 dm3solid, and in average 37 m3solid energy wood per ha and 11 m3solid pulpwood per ha were harvested. The harvesting costs for the harvester and forwarder system were on average 15965 SEK/ha. The time study shows that a harvesting system with a medium sized harvester and forwarder in energy wood thinning is profitable when the harvested tree size reaches ca 30-35 dm3solid (diameter at breast height ca 8-9 cm). These results are in line with previous finding from both Sweden and Finland. Further development of harvesting systems for integrated harvesting of energy wood and pulpwood will make the extraction of biomass from early thinning more profitable, in stands were the mean harvested tree size reach at least 30 dm3solid, in comparison to extract only one assortment.

    The Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV) is a new structured professional judgment guide for assessing short-term risks in adolescents. The scheme may be distinguished from other youth risk assessment and treatment planning instruments by its inclusion of 23 dynamic factors that are each rated for both vulnerability and strength. In addition, START:AV is also unique in that it focuses on multiple adverse outcomes-namely, violence, self-harm, suicide, unauthorized leave, substance abuse, self-neglect, victimization, and general offending-over the short-term (i.e., weeks to months) rather than long-term (i.e., years). This paper describes a pilot implementation and preliminary evaluation of START:AV in three secure juvenile correctional facilities in the southern United States. Specifically, we examined the descriptive characteristics and psychometric properties of START:AV assessments completed by 21 case managers on 291 adolescent offenders (250 boys and 41 girls) at the time of admission. Results provide preliminary support for the feasibility of completing START:AV assessments as part of routine practice. Findings also highlight differences in the characteristics of START:AV assessments for boys and girls and differential associations between the eight START:AV risk domains. Though results are promising, further research is needed to establish the reliability and validity of START:AV assessments completed in the field. PMID:23316116

    This report evaluates the feasibility of very deep borehole disposal of high-level nuclear waste, e.g., spent nuclear fuel, in the light of recent technological developments and research on the characteristics of bedrock at extreme depths. The evaluation finds that new knowledge in the field of hydrogeology and technical advances in drilling technology have advanced the possibility of using very deep boreholes (3-5 km) for disposal of the Swedish nuclear waste. Decisive factors are (1) that the repository can be located in stable bedrock at a level where the groundwater is isolated from the biosphere, and (2) that the waste can be deposited and the boreholes permanently sealed without causing long-term disturbances in the density-stratification of the groundwater that surrounds the repository. Very deep borehole disposal might offer important advantage compared to the relatively more shallow KBS approach that is presently planned to be used by the Swedish nuclear industry in Sweden, in that it has the potential of being more robust. The reason for this is that very deep borehole disposal appears to permit emplacement of the waste at depths where the entire repository zone would be surrounded by stable, density-stratified groundwater having no contact with the surface, whereas a KBS-3 repository would be surrounded by upwardly mobile groundwater. This hydro-geological difference is a major safety factor, which is particularly apparent in all scenarios that envisage leakage of radioactive substances. Another advantage of a repository at a depth of 3 to 5 km is that it is less vulnerable to impacts from expected events (e.g., changes in groundwater conditions during future ice ages) as well as undesired events (e.g. such as terrorist actions, technical malfunction and major local earthquakes). Decisive for the feasibility of a repository based on the very deep borehole concept is, however, the ability to emplace the waste without failures. In order to achieve this further research and technological development is required.

    In Sweden, about 1.3 million tonnes of ash are produced annually. Out of that amount, 150 000 - 300 000 tonnes have been estimated to originate from forest fuels, i.e. ashes that potentially can be brought back to the forest. Apart from being a compensatory measure after intensive forest harvest (e.g. including tops and branches), the ash may be used to increase the tree growth on peat soils (ash fertilization). On peat soils, tree growth is generally increased after addition of ash or phosphorous (P) and potassium (K) fertilizers. However, in some cases also nitrogen (N) addition is required. On sparsely stocked mires, fertilization may promote the regeneration as well as increase the growth of the trees. Sufficient drainage and supply of plant-available N are some prerequisites for increasing tree growth by PK-addition. In 1982, Skogforsk established a field experiment (168 Perstorp) located in the province of Scania in a sparsely stocked Pinus Sylvestris (L.) sapling stand on a ditched mire where different nutrient regimes were tested. The experiment had a randomized block design including four blocks and seven treatments. Ash and different dozes of P (raw phosphate) and K (potassium chloride), with or without simultaneous N addition, were included as well as un untreated control. The aim of the present study was to evaluate the effects on tree growth and needle elemental concentrations 26 years after treatment. The addition of similar dozes of P (approx. 40 kg P/ha), as ash (2.5 tonnes/ha) or as PK-fertilizer rendered similar growth responses. The increase in stem-wood growth was in the order of 1,6 - 1,9 m3/ha/yr during the 26-year period. The N-addition had no additional effect. On the control plots, the growth was more or less negligible (approx. 0,04 m3sk/ha/yr). On average, the high dozes of raw-phosphate and potassium chloride (40 kg P/ha and 80 kg K/ha) gave a higher growth increase than the low dozes (20 kg P/ha and 40 kg K/ha), although this effect was not statistically significant. In the low doze plots, the height growth of the main stems (to be left after a cleaning) indicated a shorter effect period. The increased tree growth on an area basis due to the nutrient addition was an effect of both an increase in the number of trees and an increased growth of these trees. The needle N concentrations indicated a sufficient N status of the Pinus sylvestris trees, which was in line with the lacking response on growth after N fertilization. In addition, the P- and K-concentrations in the needles increased significantly in the treatments with ash or PK, where the growth responses were substantial. In conclusion, sufficient drainage combined with addition of ash or PK-fertilizer on this type of mires can result in a pole stage Pinus sylvestris stand. However, the sustainability of the growth is an open question

    2010-01-01

    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

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

    Science.gov (United States)

    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.

    The chemical composition of runoff from a wood ash fertilized catchment in central Sweden has been studied during eight years after the treatment. The effects of the ash treatment was compared with a 12 year long reference period and a reference catchment close to the ash treated area was earlier (winter 1980/81) whole-tree-harvested to 90 %. At the same time the reference area was stemwood harvested on 60 % of the area. Both areas were planted with spruce and pine. Granulated ash was spread on the whole-tree-harvested area, by helicopter, on two occasions (1 ton per hectare in May 1989 and 2 tonnes per hectare in October 1991). During the first ash application a marked peak in K concentration was observed. The second ash application caused a high peak in K concentration. Short-lived peaks was also observed for pH, electric conductivity, ANC, Mg, Na and Cl. Significant increases of pH, electric conductivity, Ca, K and Cl was observed in runoff water from the ash treated area during the 8-year-period after the last ash spreading. However, during the same period concentrations of NH{sub 4}-N, NO{sub 3}-N and total N have shown a relative decrease in runoff water from the ash treated area, compared to the reference area.

    A 91-year-old woman received a dual-chamber pacemaker for sick sinus syndrome and intermittently abnormal atrioventricular (AV) conduction. The pacemaker was set in DDI mode with a 350-ms AV delay to preserve intrinsic ventricular activity. She complained of palpitation during AV sequential pacing. The electrocardiogram showed a 2:1 AV rhythm from 1:1 ventriculoatrial (VA) conduction during ventricular pacing in DDI mode with a long AV interval. After reprogramming of the pacemaker in DDD mode with a 250-ms AV interval and additional 100-ms prolongation of the AV interval by the ventricular intrinsic preference function, VA conduction disappeared and the patient's symptom were alleviated without increasing unnecessary right ventricular pacing.

Målsetningen er å øke kunnskap om og evne til å gjenkjenne tegn på psykiske problemer og lidelser, og å senke terskelen for å søke hjelp. Vi vurderer her graden av måloppnåelse.

    To give a help in the interpretation of cardiac cine-MR examination, the extent, shape, and timing of appearance of signal void regions near atrioventricular(A-V) valve prospectively evaluate in the healthy population. Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricular valve areas. Transient signal void was observed within the near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called {sup p}hysioloic atrioventricular valvular insufficiency{sup .} Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects did not show any evidence of physiologic insufficiency. 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.

    We investigate the light and radial-velocity curves of the eclipsing binary AV Del. Using the most new version of Wilson & Van Hamme (2003) code, the absolute elements, fundamental orbital and physical parameters of the system are determined. Then, using the new SHELLSPEC code, we study and present an accretion disc model for the system. We found AV Del is a semi-detached system which has an accretion disc around the primary star. By combining the radial-velocity and light curve analysis, we derive accurate absolute masses for the components of M1=1.449 Msun and M2 =0.687 Msun and radii of R1=2.61 Rsun and R2=4.21 Rsun as well as effective temperatures of T1=6000 K and T2= 4281 K for the primary and the secondary, respectively. Also, we derived a temperature of T=5700 K for the disc. Finally, our results are compared with those of previous authors.

    2006-01-01

    A new audio and video compression standard of China, known as advanced Audio Video coding Standard (AVS),is emerging. This standard provides a technical solution for many applications within the information industry such as digital broadcast, high-density laser-digital storage media, and so on. The basic part of AVS, AVS1-P2, targets standard definition (SD) and high definition (HD) format video compression, and aims to achieve similar coding efficiency as H.264/AVC but with lower computational complexity. In this paper, we first briefly describe the major coding tools in AVS1-P2, and then perform the coding efficiency comparison between AVS1-P2 Jizhun profile and H.264/AVC main profile. The experimental results show that the AVS1-P2 Jizhun profile has an average of 2.96% efficiency loss relative to H.264/AVC main profile in terms of bit-rate saving on HD progressive-scan sequences, and an average of 28.52% coding loss on interlace-scan sequences.Nevertheless, AVS1-P2 possesses a valuable feature of lower computational complexity.

    2002-01-01

    Objectives: This study was aimed at assessing the value of the adenosine test for noninvasive diagnosis of dual AV nodal physiology(DAVNP) in patients with AV nodal reentrant tachycardia (AVNRT). Methods: 53 patients with paroxysmal supraventricular tachycardia (PSVT) were given incremental doses of adenosine intravenously during sinus rhythm before electrophysiological study. The adenosine test was repeated on a subset of 18 patients with AVNRT after radiofrequency catheter ablation. Results: Sudden increments of PR interval of more than 60 msec between two consecutive beats were observed in 26(83.9%) of 31 patients with typical AVNRT and 2 (9.1%) of 22 patients with AVRT and AT (P<0.01). The maximal PR increment between 2 consecutive beats in the AVNRT group(105±45ms) was significantly greater than that in the AVRT and AT group (20±13ms) (P<0.01).In postablation adenosine test, DAVNP was eliminated in all 8 patients who underwent slow pathway abolition that EPS showed the slow pathway disappeared and 4 of 10 patients who underwent slow pathway modification that EPS showed the slow pathway persisted. Six of 10 patients who exhibited persistent duality showed a marked reduction in the number of beats conducted in the slow pathway after adenosine injection(P<0.01).Conclusions: Administration of adenosine during sinus rhythm may be a useful bedside test for diagnosis of DAVNP in high percentage of patients with typical AVNRT and additionally for evaluating the effects of radiofrequency ablation.

    2011-01-01

    Kultivert jord er den viktigaste antropogene kjelda til dinitrogenoksid (N2O), også kalla lystgass. N2O er ein klimagass og bidreg til øydelegging av stratosfærisk ozon. Dyrka myrjord har ein større emisjon av N2O enn mineraljord. Sjølv om dyrka myrjord berre utgjer 7 – 8 % av det totale dyrka arealet i Noreg, kan dei potensielt vere ein stor bidragsytar til N2O - emisjonen frå norsk jordbruk. pH i jord er ein nøkkelvariabel for dei fleste biologiske prosessane i jorda. Kalking kan føre ti...

    2016-04-01

    Full Text Available I utdanningsvitenskapelig litteratur er ulike former for ”literacy” et vedvarende fokus både teoretisk og empirisk. I engelskspråklig naturfagdidaktisk litteratur brukes betegnelsen ”scientific literacy”. Jeg skisserer i denne artikkelen et planleggingsverktøy for undervisning som bygger på en eksplisitt teoretisk modell for deltakelse gjennom språk. Modellen er bindeledd mellom et generalisert kompetansebegrep og planlegging av undervisning ved at den knytter sammen de didaktiske spørsmålene hva, hvem, hvordan og hvorfor med en modell for funksjonell deltakelse. Modellen er spesielt relevant for et allmenndannende ”naturfag for alle”, men favner også et naturfag som fokuserer på utdanning av framtidas naturvitere. Artikkelen retter seg mot naturfag i skolen, men modellen bør kunne anvendes også i andre skolefag. Modellen peker mot et situert og transformativt kompetansebegrep.Nøkkelord: naturfag , kompetanse , diskurs , deltakelse, undervisning og læringAbstractVarious forms of literacy have long been the focus of educational discourses, not the least in science education where the term “scientific literacy” has been an enduring concern for decades. In this article I describe a tool for designing teaching based on a theoretical perspective on participation through language. The model connects a general conception of competence with the planning of teaching. To do so it drowe on the didactical questions of “what, who, how and why”. The model is particularly relevant in a “science for all” perspective but also for the educating of future science specialists. Although school science is the primary focus in this article, the model should be applicable to other school subjects as well. The model opens for a situated and transformative notion of competence.Keywords: scientific literacy, discourse, participation, teaching and learning
