    Full Text Available The brown planthopper, Nilaparvata lugens is one of the most serious pests of rice, and there is so far no effective way to manage this pest. However, RNA interference not only can be used to study gene function, but also provide potential opportunities for novel pest management. The development of wing plays a key role in insect physiological activities and mainly involves chitin. Hence, the regulating role of trehalase (TRE genes on wing bud formation has been studied by RNAi. In this paper, the activity levels of TRE and the contents of the two sugars trehalose and glucose were negatively correlated indicating the potential role of TRE in the molting process. In addition, NlTRE1-1 and NlTRE2 were expressed at higher levels in wing bud tissue than in other tissues, and abnormal molting and wing deformity or curling were noted 48 h after the insect was injected with any double-stranded TRE (dsTRE, even though different TREs have compensatory functions. The expression levels of NlCHS1b, NlCht1, NlCht2, NlCht6, NlCht7, NlCht8, NlCht10, NlIDGF, and NlENGase decreased significantly 48 h after the insect was injected with a mixture of three kinds of dsTREs. Similarly, the TRE inhibitor validamycin can inhibit NlCHS1 and NlCht gene expression. However, the wing deformity was the result of the NlIDGF, NlENGase, NlAP, and NlTSH genes being inhibited when a single dsTRE was injected. These results demonstrate that silencing of TRE gene expression can lead to wing deformities due to the down-regulation of the AP and TSH genes involved in wing development and that the TRE inhibitor validamycin can co-regulate chitin metabolism and the expression of wing development-related genes in wing bud tissue. The results provide a new approach for the prevention and management of N. lugens.

    Full Text Available A qualitative study of nursing students' experience of new learning activities in critical evaluation of quantitative research articles Evidence-Based Practice is a vital part of professional health care and nurses need to have knowledge of research. This article presents nursing students' experience with new learning activities in critical evaluation of quantitative research articles. This experience was studied in focus group interviews with second-year nursing students. The students described it as challenging to understand the various quantitative designs and statistical methods. Specific requirements in the learning activities, constructive feedback, relevance and conformity between learning activities and assessments seem to promote the targeted learning outcome. How students' knowledge and skills are received in practice seems to affect students' attitudes and behavior in relation to the application of research results. To increase evidence-based practice there appears to be a need for innovative processes that can strengthen the cooperation between the nursing education and the field of practice.

  15. A novel device for measuring arterial stiffness using finger-toe pulse wave velocity: Validation study of the pOpmètre®.

    The finger-toe pathway could be a good alternative for assessing arterial stiffness conveniently. To evaluate the accuracy of the pOpmètre®--a new device that measures finger-toe pulse wave velocity (ft-PWV). The pOpmètre has two photodiode sensors, positioned on the finger and the toe. Pulse waves are recorded continuously for 20 seconds, and the difference in pulse wave transit time between toe and finger (ft-TT) is calculated. The travelled distance is estimated using subject height. Study 1 compared ft-PWV with carotid-femoral PWV (cf-PWV) obtained by the reference method (SphygmoCor®) in 86 subjects (mean age 53±20 years), including 69 patients with various pathologies and 17 healthy normotensives. Study 2 compared changes in ft-PWV and cf-PWV during a cold pressor test in 10 healthy subjects. Study 3 assessed repeatability in 45 patients. ft-PWV correlated significantly with cf-PWV (R2=0.43; P<0.0001). A better correlation was found in terms of transit time (R2=0.61; P<0.0001). The discrepancy between transit times was related to age. The cold pressor test induced parallel changes in cf-PWV and ft-PWV, with increased aortic stiffness that was reversible during recovery. Intra-session repeatability was very good, with a coefficient of variation of 4.52%. The pOpmètre® allows measurement of arterial stiffness in routine clinical practice. The greatest advantages of ft-PWV are simplicity, rapidity, feasibility, acceptability by patients and correct agreement with the reference technique. Further studies are needed to adjust for bias and to validate the pOpmètre in larger populations. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  16. Hvor moralsk tenker fotballspillere? – en empirisk studie av toppfotball

    2015-11-01

    Full Text Available Det er en utbredt oppfatning at det økende prestasjonskravet i toppfotball fører til en svekkelse av moral og fair play-holdninger. Men hvordan tenker toppfotballspillere i forhold til ulike dilemmaer som oppstår på banen, og er det forskjeller mellom toppfotballspillere og spillere på lavere nivå?  For å avklare dette gjennomførte vi en empirisk undersøkelse der vi intervjuet spillere og trener i én toppklubb og én breddeklubb. Vi var interessert i to hovedproblemstillinger:  1 Hva tenker fotballspillere på ulike prestasjonsnivå om etikk og moralske dilemmaer i fotball? 2 Hvilke faktorer påvirker spillerne, direkte og indirekte, i deres vurderinger og handlinger? Resultatene fra undersøkelsen viser at det er store forskjeller mellom de to prestasjonsnivåene. Spillerne på breddenivået føler generelt et større ansvar for å opptre ærlig på banen enn hva som er tilfelle på toppnivået. Vi fant 4 spesifikke faktorer i toppfotballen som bidrar til umoralsk opptreden. For det første opplever spillerne en forventning om at de prioriterer resultat foran fair play. For det andre bidrar tilstedeværelsen av supportere på kamper til en slik prioritering. For det tredje vil handlinger som er i strid med fair play signaliseres som akseptable internt i miljøet, selv om de ofte signaliseres som uakseptable overfor media og omverdenen. For det fjerde kan spillere oppleve det som vanskelig å gå i mot trenerens oppfordringer til en pragmatisk og resultatfokusert opptreden.Nøkkelord: moral, etikk, fair play, footballEnglish summary: How morally do football players think? – an empirical study of moral dilemmas in elite footballIt is a common view that the increasing focus on achievement and success in elite football leads to a weakening of moral and fair play attitudes.

    Despite the growing number of oral agents available for cancer treatment, their efficacy may be reduced due to the lack of adherence, inappropriate adverse event self-management and arbitrary dose adjustment. The management of anticancer therapies could exponentially benefit from the introduction of mobile health technologies in a highly integrated electronic oncology system. We plan to customise and fine-tune an existing monitoring TreC platform used in different chronic diseases in the oncology setting. This project follows a multistep approach with two major purposes: 1. participatory design techniques driven by Health Literacy and Patient Reported Outcomes principles in order to adapt the system to the oncology setting involving patients and healthcare providers; 2. a prospective training-validation, interventional, non-pharmacological, multicentre study on a series of consecutive patients with cancer (20 and 60 patients in the training and validation steps, respectively) in order to assess system capability, usability and acceptability. The novel Onco-TreC 2.0 is expected to contribute to improving the adherence and safety of cancer care, promoting patient empowerment and patient-doctor communication. Ethical approval was obtained from the Independent Ethics Committees of the participating institutions (CEIIAV protocol Number 2549/2015; reference Number 1315-PU). Informed consent will be obtained from all study participants. Findings will be disseminated through peer-reviewed journals, conferences and event presentations.

    The purpose of this summary is to specify the quality demands imposed by pellet users on the manufacturers of pellets, the testing methods that are used for manufacturing inspection at factories, and the type of acceptance inspection that is conducted at district heating plants and combined heat and power plants. A further task of the study has been to provide advice and guidelines to pellet users on how to carry out their acceptance inspection. During the course of the study, we have contacted and interviewed 8 Swedish users and 7 Swedish producers of pellets and asked them what type of quality control they employ at their heating plants and factories. The study shows that the users impose relatively stringent demands on pellet producers with regard to pellet quality. The parameters checked include energy content, moisture content, ash content, grain size, grain size distribution, the origin of the raw materials, resistance, weight, chemical bonding, sulphur content, chlorine content and analysis of metal content. Most of the above parameters are checked at various intervals, some every other hour or on each delivery and others several times every year. In the case of those users who only have one fuel supplier, we recommend limited acceptance inspection on the assumption that the supplier conducts the inspection that he has undertaken to perform under the terms of his agreement with the users. Users should, however, check the information and at some time during the year visit the pellet producer to make sure that the agreed procedures are being followed. In the case of those users with many different fuel suppliers, we recommend fairly extensive acceptance inspection. Those parameters that should be checked, but at different intervals, are energy content, moisture content, ash content, grain size, grain size distribution, the origin of raw materials, resistance, weight, chemical bonding, sulphur content, chlorine content and analysis of metal content.

    To evaluate the efficacy and safety of intravitreal sirolimus in the treatment of noninfectious uveitis (NIU) of the posterior segment (i.e., posterior, intermediate, or panuveitis). Phase III, randomized, double-masked, active-controlled, 6-month study with intravitreal sirolimus. Adults with active NIU of the posterior segment (intermediate, posterior, or panuveitis), defined as a vitreous haze (VH) score >1+. Subjects discontinued NIU medications before baseline, except for systemic corticosteroids, which were allowed only for those already receiving them at baseline and were rapidly tapered after baseline per protocol. Intravitreal sirolimus assigned 1:1:1 at doses of 44 (active control), 440, or 880 μg, administered on Days 1, 60, and 120. The primary efficacy outcome was the percentage of subjects with VH 0 response at Month 5 (study eye) without use of rescue therapy. Secondary outcomes at Month 5 were VH 0 or 0.5+ response rate, corticosteroid tapering success rate (i.e., tapering to a prednisone-equivalent dosage of ≤5 mg/day), and changes in best-corrected visual acuity (BCVA). Adverse events during the double-masked treatment period are presented. A total of 347 subjects were randomized. Higher proportions of subjects in the intravitreal sirolimus 440 μg (22.8%; P = 0.025) and 880 μg (16.4%; P = 0.182) groups met the primary end point than in the 44 μg group (10.3%). Likewise, higher proportions of subjects in the 440 μg (52.6%; P = 0.008) and 880 μg (43.1%; P = 0.228) groups achieved a VH score of 0 or 0.5+ than in the 44 μg group (35.0%). Mean BCVA was maintained throughout the study in each dose group, and the majority of subjects receiving corticosteroids at baseline successfully tapered off corticosteroids (44 μg [63.6%], 440 μg [76.9%], and 880 μg [66.7%]). Adverse events in the treatment and active control groups were similar in incidence, and all doses were well tolerated. Intravitreal sirolimus 440 μg demonstrated a significant

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

Temaet i rapporten er nordmenns spise- og drikkemønster av en type mat og drikke som helsemyndighetene ønsker at befolkningen skal redusere forbruket sitt av – slik som sjokolade, søtsaker, søte bakervarer, salt snacks og sukkerholdige drikker. Selv om forbruksutviklingen de seneste par årene har vist positive tendenser, har altså nordmenn fremdeles et langt høye...

  6. Konsum av risiko-matvarer - Beskrivelse av en undersøkelse som skal kartlegge konsum av matvarer med betydning for inntaket av miljøgifter

    Directory of Open Access Journals (Sweden)

    Helle Margrete Meltzer

    2009-11-01

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

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

  18. 15-åringers opplevelser av overvekt hos jevnaldrende, en fenomenologisk-hermeneutisk studie

    Directory of Open Access Journals (Sweden)

    Reidun Rognsaa

    2011-06-01

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

    Depression and binge drinking behaviours are common clinical problems, which cause substantial functional, economic and health impacts. These conditions peak in young adulthood, and commonly co-occur. Comorbid depression and binge drinking are undertreated in young people, who are reluctant to seek help via traditional pathways to care. The iTreAD project (internet Treatment for Alcohol and Depression) aims to provide and evaluate internet-delivered monitoring and treatment programs for young people with depression and binge drinking concerns. Three hundred sixty nine participants will be recruited to the trial, and will be aged 18-30 years will be eligible for the study if they report current symptoms of depression (score 5 or more on the depression subscale of the Depression Anxiety Stress Scale) and concurrent binge drinking practices (5 or more standard drinks at least twice in the prior month). Following screening and online baseline assessment, participants are randomised to: (a) online monthly self-assessments, (b) online monthly self-assessments + 12-months of access to a 4 week online automated cognitive behaviour therapy program for binge drinking and depression (DEAL); or (c) online monthly assessment + DEAL + 12-months of access to a social networking site (Breathing Space). Independent, blind follow-up assessments occur at 26, 39, 52 and 64-weeks post-baseline. The iTreAD project is the first randomised controlled trial combining online cognitive behaviour therapy, social networking and online monitoring for young people reporting concerns with depression and binge drinking. These treatments represent low-cost, wide-reach youth-appropriate treatment, which will have significantly public health implications for service design, delivery and health policy for this important age group.

  10. Magnetic excitations in low-dimensional spin systems: neutron scattering study on AV2O5

    International Nuclear Information System (INIS)

    Nakajima, Kenji

    1997-01-01

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

  11. The Meter arrives. A study of the information around the introduction of individual electricity meters; Maetaren kommer. En studie av informationen kring infoerandet av individuella elmaetare

    Energy Technology Data Exchange (ETDEWEB)

    Maardsjoe Blume, Karin; Lindstedt, Inger

    2008-10-15

    From 1st July 2009 all electricity meters will be read once a month, which means that individual electricity meters will be installed for all users - private customers and businesses alike. This change will create the need for information to be circulated to the users about what will happen, why and what is expected of users. With a specific focus on the relation with private customers, the aim of this study has been to describe and analyse the information and communication strategies used by electricity and energy companies. The methodology has largely consisted of text and material analyses, in combination with an in-depth interview in order to study a company's entire communication chain. The material studied has consisted of ELAN-companies' information material and campaigns. The study's long-term objective is to contribute to a better understanding between user and company and improved knowledge of the field. Which information and communication strategies have been identified in the analysis? Three main areas are in focus here: the choice of genre, the choice of rhetorical approach and the interplay and overlap of texts and images. In terms of genre, it is clear that the spectrum is both wide and varied: letters, brochures, advertisements, postcards, 'road shows' with celebrities as attractions, etc. As the information requirement is great, the choice of genre and the creation of different kinds of material and campaigns are also wide-ranging. The companies have chosen to work in different ways, however, and the dividing line seems to be set between large and small companies, or in other words, companies with or without strong local ties. The companies with strong local connections - and generally speaking not very large - tend to use letters and personal contact. The large international companies make use of a number of contact channels to both stimulate customer interest and make contact. The rhetorical approach relates to the focus

    1992-09-01

    Work environments at landfill gas plants were studied. In the pump station and compressor station, equipment is installed which gives an alarm at high concentration of methane, dangerous temperatures and pressure variation in the landfill gas. Risk for gas collection exists in enclosed spaces such as gas wells and leachate wells. The report proposes measures to improve the personnel`s safety at all work situations in these locations. The strong odour from waste constitutes a problem for compactor drivers and workers laying gas pipes or digging gas wells. Several organic compounds such as methanethiol, dimethyl sulphide, ethyl butanoate etc. with a very low odour threshold are formed by degradation of waste and these compounds are strong-smelling. Several suggestions on how to improve the working conditions at the biocells are given in this report. The highest concentrations of dust were measured during tipping of waste into a receiving bunker or on the unloading platform. This report suggests how to reduce exposure to organic dust, bacteria and endotoxins. During recent years, several landfills has started to use leachate for irrigation of energy forests. As leachate contains microorganisms, the spreading of aerosols should be limited so that personnel is not exposed to leachate mists during spray irrigation. In this study, the occupational accidents and diseases that has occurred in the landfills were compiled. An increase of the frequency of injuries has been observed in recent years (1986-1990). Sprains and dislocations were the most common type of occupational injuries among all reported accidents. Musculoskeletal diseases dominated among the registered occupational diseases. 21 refs.

This report suggests how to reduce exposure to organic dust, bacteria and endotoxins. During recent years, several landfills has started to use leachate for irrigation of energy forests. As leachate contains microorganisms, the spreading of aerosols should be limited so that personnel is not exposed to leachate mists during spray irrigation. In this study, the occupational accidents and diseases that has occurred in the landfills were compiled. An increase of the frequency of injuries has been observed in recent years (1986-1990). Sprains and dislocations were the most common type of occupational injuries among all reported accidents. Musculoskeletal diseases dominated among the registered occupational diseases. 21 refs.

  15. Læring innen toppfotball : en studie av forholdet mellom coaching og mesterlære som læringsteorier, og deres potensial og rolle i toppfotball

    Tema og problemstilling Jeg har bakgrunn som fotballspiller og har i den forbindelse vært svært opptatt av hvordan man best kan legge til rette for utvikling av fotballspillere. Gjennom mine pedagogikkstudier har to læringsteorier fasinert meg i forhold til fotball, nemlig coaching og mesterlære. Disse to teoriene skiller seg tydelig fra hverandre og er på mange måter motsetninger. Dette var noe jeg ønsket å gå dypere inn i, og derfor endte denne masteroppgaven opp med en studie av coachin...

    joined a three year NSF funded project - Collaborative Research: An integrated seismic-geodetic study of active magmatic processes at Sierra Negra volcano, Galapagos Islands, http://sierranegragalapagos.blogspot.com. In 2010, with the help of Stanford researchers, I used NSF funding, gelatin and water balloons to build a model 8th grade Algebra students can use to physically and mathematically demonstrate the process of inverting geodetic data to image the magma chamber of a volcano. And, in 2011, a SCEC intern is using seismic data from Sierra Negra to build a visualization for students of the volcano's magma chamber and its changes over time. As a direct result of my first TRE, my students answer their own questions about seafloor vents, explore volcanoes through mathematical and physical modeling, collaborate with students, teachers and researchers, and for field experience, through a Toyota Tapestry Grant they conduct seasonal plot studies with Stanford student mentors at Stanford's Jasper Ridge Biological Preserve. Based on my experiences the "rest of the story" is more interesting than a report on the first TRE. TRE veterans have insights to share.

    Holmgren, Magnus Andreas (SP, Boraas (Sweden)); Willen, Agnes; Rodhe, Lena (JTI, Uppsala (Sweden))

    2011-11-15

    Previous work in areas such as framework of voluntary commitment shows that there is a need for techniques for measurement of methane and other greenhouse gases from various sources in the handling of organic residuals. There are no established methods for determining for instance emissions of methane from open or partially open tanks and cisterns, typically residue storage and the like. This report gives results from Phase 1 of this project, in which literary studies, market research studies, interviews and site visits have been made to identify a number of methods applied for the determination of emissions from open areas, such as liquid surfaces, but also land. Focus is on methods that can be applied to plants for biological treatment, which also includes the water treatment process at the treatment plants, but also the procedures used in measurements on land, landfills and processing plants are studied. First, the report gives a brief overview of a large number of measurement methods, where more detailed descriptions of four methods are given. The four methods are considered to be the most promising to pursue in the following phases of the project: - chamber technology; - sampling hood; - plume measurement with DIAL (Differential Absorption Lidar); - air input in a covered storage.

    2010-07-01

    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

    SKB hands every year over, on behalf of the power companies, to SKI a cost calculation for spent fuel handling and dismantling of the Swedish nuclear power plants. SKI has tried to investigate the future impact which the growth of money in the Nuclear Waste Fund might give in relation to the change of consumer price index, CPI. The long term yield of the Fund has been related to the change of CPI, as the bigger part of the fund money has been invested in real interest rate bonds, issued by the Swedish state. The cost development has been studied with an index named 'KBS-3-index', which is a basket of weighted factor price indexes based on the SKB programme. Since 1986 and up to 2002, the KBS-3-index has increased about 102%, but CPI only about 70%. If this discrepancy should continue during the whole period when Fund money should be available, the Fund would be insufficient. But the difference between KBS-3-index and CPI might be eliminated due to a future productivity development. At the moment, SKI has no knowledge about future productivity development in the SKB programme. A closer analysis of the productivity and efficiency development in the facilities operated by SKB is therefore applicable. Nearest to study is the productivity at the operation of CLAB, Central Interim Storage Facility for Spent Nuclear Fuel. The work in CLAB is receiving and storing of spent nuclear fuel and core components. The consumption of all production factors can be measured in economical means. Here the total production factors are defined as the sum of the annual operation costs and the sum of annuities for reinvestments during the year. The development of total productivity is increasing slightly, but decreasing in the end. Normal for a new business is that the productivity is rising sharply in the beginning. Here the productivity is slightly decreasing in the beginning, and then rising, decreasing, rising and finally decreasing. The project 'compact storing

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

    On behalf of Enova SF, Prognosesenteret AS and Entelligens AS carried out a potential and barrier study of energy efficiency of the Norwegian housing stock. The study made use of newer and known studies of the Norwegian housing stock, known and documented barriers to energy efficiency, and new and extensive studies of several topics which have only been partially or never explored before. Through unique analysis and a case-based approach, it revealed a real energy efficiency potential in Norwegian homes with known technology and revealed representativeness, relevance, strength and extent of the barriers that prevent that one can realize most of the technical energy efficiency potential in the Norwegian housing stock.

    Larsson, Per-Erik

    2012-02-15

    High forest production leads to diminishing amounts of base cations and micro nutrients in forest soils. This is due to uptake in, and harvest of, the trees. Losses can be compensated for by spreading stabilized wood ash on the forest ground, which means recycling of base cations and micro nutrients. Chemical composition of wood ash can easily be described by standard methods in the laboratory. However, this does not include the process of leaching in nature, such as which components and leaching rate for different compounds. During field conditions several factors are added, which are not available in the laboratory. After almost 10 years in the forest soils there still remains large quantities of the original product. Only 10-30 % of the wood ash products and 5 % of the lime product has been leached. In the laboratory study the leached amount was slightly larger, at the most 35 % for wood ash and 20 % for lime. Both studies indicate long time for weathering of the products in forest soils. Slower leaching rate from pellets of wood ash compared to leaching rate from crushed wood ash in the laboratory study is not verified by the field study. This indicates limited possibilities to control rates of leaching in the environment

    The successive deregulation of the market for electric power, in Sweden as well as abroad, results in an increased competition in generation and trade of electricity. This market that previously was known for its oligopoly in the production sector and its monopoly in the distribution sector has now been opened for competition. This study is focused on the district heating sector, because it is still comparatively unregulated, and because it partly comprises what is called natural monopolies.

    This project aims to characterize chemical and subsequently odor emissions from a digester plant located closed to Boraas in Sweden (Boraas Energi och Miljoe AB). The digestion produces mainly 2 by-products, biogas and high quality organic biofertilizer. Biogas is a renewable source of electrical and heat energy and subsequently digester have a promising future. Unfortunately, release of unpleasant odours is one of the problems that may limit development of the technique as odours strongly influence the level of acceptance of the neighbours. The number of complaints due to odours depends mostly, upon the degree of odour release, the weather condition and plant environment (which influence the risks for spreading out), and the tolerance of the neighbours. These parameters are strongly variable. Many processes inside the plant distributed on a large surface may contribute to odour release. Chemical emissions were studied, in this project, by extensive sampling inside the plant. Results were then evaluated regarding risk for odour releases. The goal was to suggest controls and routines to limit releases. The conditions leading to the higher risks for odour emissions were studied by performing sampling at different periods of the year and subsequently different weather conditions. At first, places for measurement were chosen together with personal of the plant. Three zones are considered to mainly contribute to the odour emissions: the landfill region, the cisterns region and the leaching lake region. Totally 13 places were studied with regard to odour and chemical emissions under 2008-2009 at different weather conditions. Some results from a previous project (2007) are also presented here. Results show that the spreading out of can be maintained to an acceptable level as long as the plant is functioning without disturbances. The early stages of the treatment of waste should be confined in locals with closed doors to avoid spreading out of odours. Through controlled

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

    A pre project aiming at the end to create demonstration examples of full scale professional kitchens is reported. To create a big impact school meals were chosen for the investigation. In Sweden all children are during the day given a cooked lunch. For that reason large kitchens exist in all schools. There are two main different organizations. A central kitchen delivers hot meals to each school where the meals are served to the children. The other model is local kitchens in each school. There are more non technical differences between different communities making the need to analyze more than one kitchen of each type. The two parameters in the study are energy and wasted food

  11. Processing biofuels from farm raw materials - A systems study; Pelletering och brikettering av jordbruksraavaror - En systemstudie

    2008-03-15

    Use of processed biofuels (pellets, briquettes) has greatly increased in Sweden in recent decades, mainly to replace fossil fuels in large boilers, e.g. in coal powder boilers. More recently, the demand from private households and residential heating systems has also increased, mainly due to conversion from fossil heating oil. This increased interest in pellets and briquettes for heating is beginning to cause a shortage of the traditional raw materials, sawdust and wood shavings, and therefore attention is turning to using a variety of agricultural products as raw material. Such raw materials include cultivated energy crops and wastes and by-products from agriculture. This study describes the typical systems currently used for production of pellets and briquettes and investigates the possibility of using energy crops (Salix, reed canary-grass and hemp) and various wastes and by-products from processing of farm products (straw, cereal screenings, rape-seed meal and distiller's waste) as raw materials. Previous experiences of pelletizing and briquetting of these raw materials are reviewed in order to comprehensively identify possible combustion problems that may occur. On the basis of the results obtained, scenarios for possible production systems in a five-year perspective are presented and the costs and energy demands for these systems calculated. These future scenarios include large scale plants and micro-scale plants, as well as static and mobile equipment. The five main conclusions from the study are: - The farm raw materials of greatest interest for large-scale production are pelleted Salix and reed canary-grass. They have competitive prices and acceptable fuel properties and could be mixed with sawdust in existing large-scale pelletizing factories in Sweden. - Straw has low production costs but can cause serious ash-related problems. Hemp has too high production costs to be of commercial interest, while distiller's waste and rape-seed meal currently

    Polymeric materials are frequently used in concrete constructions at hydro and nuclear power facilities. They are most commonly used as expansion joints, seals, lead-thought's, coatings and as additives in cement or mortar. Polymeric materials in concrete constructions are difficult to evaluate, since they are often located within the concrete construction. In some cases the materials have been in place for over 30 years. In addition, these materials are also used to a great extent e.g. as protective coating on all concrete in a nuclear power plant or as several kilometres of joints. Replacing these materials is difficult, time consuming and very costly. That is why it is of great importance to evaluate their actual status and life-time expectancy with the largest possible precision. This report summarises the research needs in nuclear and hydro power regarding polymers in concrete constructions. During the project information has been gathered through inspections, interviews and surveys, to obtain the clearest possible picture of which polymeric components that have a need of in-depth research. In this project the nuclear power plants Oskarshamn (O1, O2 and O3), Forsmark (F2) and Ringhals (R1, R2 and R3) were visited. In the field of hydro power the concrete laboratory of Vattenfall R and D in Aalvkarleby and the hydro power plants of Aalvkarleby and Olidan were visited. The studies indicate that there are different needs for hydro and nuclear power. The survey showed that hydro-power facilities have a greater interest in joints. The nuclear power plants are more interested in components that are related to either the plant's security or if the component could lead to high future maintenance costs.

    In Japan, expenses for landfilling yield about 400 USD per ton of ash, which gives an incentive to reduce the amount of landfilled ash. At NIES (National Institute for Environmental Studies) in Tsukuba, Japan, the AMT process (Accelerated Mineralization Technology) was developed aiming at the treatment of ashes and production of soil-like material for reuse. The objective of the project EJA was to evaluate the AMT process on the basis of available information and the possibilities the process could offer with respect to the conditions present in Sweden. With support of researchers at NIES, available literature including unpublished manuscripts on the AMT process was compiled, translated and evaluated. During treatment, the ashes are washed, aged and mixed with up to 5 % by weight of biodegradable organic matter. The material is stabilized at landfill. During up to several decades, metals are demobilized through a combination of three mechanisms, viz. carbonation, clay formation, and humification. Also persistent organic pollutants (POP) are demobilized due to humification products or they are degraded anaerobically. When the treatment is completed, the reuse of the material is envisaged. Due to the long treatment period, the AMT method might not be favored by ash producers in Sweden. In the future, landfill companies could be interested in the technology, since they are experienced to handle waste at long sight. This, however, requires that the legislation does not pose any hindrance for the implementation of the method, e.g. regarding the requirement to add organic matter to the ash. Above all, it remains several years of research on the AMT process to fully understand and evaluate the underlying biological and chemical processes as well as their interaction.

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

  18. Excision of HIV-1 proviral DNA by recombinant cell permeable tre-recombinase.

    Directory of Open Access Journals (Sweden)

    Lakshmikanth Mariyanna

    Full Text Available Over the previous years, comprehensive studies on antiretroviral drugs resulted in the successful introduction of highly active antiretroviral therapy (HAART into clinical practice for treatment of HIV/AIDS. However, there is still need for new therapeutic approaches, since HAART cannot eradicate HIV-1 from the infected organism and, unfortunately, can be associated with long-term toxicity and the development of drug resistance. In contrast, novel gene therapy strategies may have the potential to reverse the infection by eradicating HIV-1. For example, expression of long terminal repeat (LTR-specific recombinase (Tre-recombinase has been shown to result in chromosomal excision of proviral DNA and, in consequence, in the eradication of HIV-1 from infected cell cultures. However, the delivery of Tre-recombinase currently depends on the genetic manipulation of target cells, a process that is complicating such therapeutic approaches and, thus, might be undesirable in a clinical setting. In this report we demonstrate that E.coli expressed Tre-recombinases, tagged either with the protein transduction domain (PTD from the HIV-1 Tat trans-activator or the translocation motif (TLM of the Hepatitis B virus PreS2 protein, were able to translocate efficiently into cells and showed significant recombination activity on HIV-1 LTR sequences. Tre activity was observed using episomal and stable integrated reporter constructs in transfected HeLa cells. Furthermore, the TLM-tagged enzyme was able to excise the full-length proviral DNA from chromosomal integration sites of HIV-1-infected HeLa and CEM-SS cells. The presented data confirm Tre-recombinase activity on integrated HIV-1 and provide the basis for the non-genetic transient application of engineered recombinases, which may be a valuable component of future HIV eradication strategies.

    Image-guided endovascular intervention (EIGI), using new flow modifying endovascular devices for intracranial aneurysm treatment is an active area of stroke research. The new polyurethane-asymmetric vascular stent (P-AVS), a vascular stent partially covered with a polyurethane-based patch, is used to cover the aneurysm neck, thus occluding flow into the aneurysm. This study involves angiographic imaging of partially covered aneurysm orifices. This particular situation could occur when the vascular geometry does not allow full aneurysm coverage. Four standard in-vivo rabbit-model aneurysms were investigated; two had stent patches placed over the distal region of the aneurysm orifice while the other two had stent patches placed over the proximal region of the aneurysm orifice. Angiographic analysis was used to evaluate aneurysm blood flow before and immediately after stenting and at four-week follow-up. The treatment results were also evaluated using histology on the aneurysm dome and electron microscopy on the aneurysm neck. Post-stenting angiographic flow analysis revealed aneurysmal flow reduction in all cases with faster flow in the distally-covered case and very slow flow and prolonged pooling for proximal-coverage. At follow-up, proximally-covered aneurysms showed full dome occlusion. The electron microscopy showed a remnant neck in both distally-placed stent cases but complete coverage in the proximally-placed stent cases. Thus, direct flow (impingement jet) removal from the aneurysm dome, as indicated by angiograms in the proximally-covered case, was sufficient to cause full aneurysm healing in four weeks; however, aneurysm healing was not complete for the distally-covered case. These results support further investigations into the treatment of aneurysms by flow-modification using partial aneurysm-orifice coverage.

    Purpose: The compound (E)-4-(2-(6-(2-(2-(2-{sup 18}F-fluoroethoxy)ethoxy)ethoxy) pyridin-3-yl)vinyl)-N-methylbenzenamine ([{sup 18}F]AV-45) is a novel radiopharmaceutical capable of selectively binding to {beta}-amyloid (A{beta}) plaques. This pilot study reports the safety, biodistribution, and radiation dosimetry of [{sup 18}F]AV-45 in human subjects. Methods: In vitro autoradiography and fluorescent staining of postmortem brain tissue from patients with Alzheimer's disease (AD) and cognitively healthy subjects were performed to assess the specificity of the tracer. Biodistribution was assessed in three healthy elderly subjects (mean age: 60.0{+-}5.2 years) who underwent 3-h whole-body positron emission tomography (PET)/computed tomographic (CT) scans after a bolus injection of 381.9{+-}13.9 MBq of [{sup 18}F]AV-45. Another six subjects (three AD patients and three healthy controls, mean age: 67.7{+-}13.6 years) underwent brain PET studies. Source organs were delineated on PET/CT. All subjects underwent magnetic resonance imaging (MRI) for obtaining structural information. Results: In vitro autoradiography revealed exquisitely high specific binding of [{sup 18}F]AV-45 to postmortem AD brain sections, but not to the control sections. There were no serious adverse events throughout the study period. The peak uptake of the tracer in the brain was 5.12{+-}0.41% of the injected dose. The highest absorbed organ dose was to the gallbladder wall (184.7{+-}78.6 {mu}Gy/MBq, 4.8 h voiding interval). The effective dose equivalent and effective dose values for [{sup 18}F]AV-45 were 33.8{+-}3.4 {mu}Sv/MBq and 19.3{+-}1.3 {mu}Sv/MBq, respectively. Conclusion: [{sup 18}F]AV-45 binds specifically to A{beta} in vitro, and is a safe PET tracer for studying A{beta} distribution in human brain. The dosimetry is suitable for clinical and research application.

    Purpose AV-45 amyloid biomarker is known to show uptake in white matter in patients with Alzheimer’s disease (AD) but also in healthy population. This binding; thought to be of a non-specific lipophilic nature has not yet been investigated. The aim of this study was to determine the differential pattern of AV-45 binding in healthy and pathological populations in white matter. Methods We recruited 24 patients presenting with AD at early stage and 17 matched, healthy subjects. We used an optimized PET-MRI registration method and an approach based on intensity histogram using several indexes. We compared the results of the intensity histogram analyses with a more canonical approach based on target-to-cerebellum Standard Uptake Value (SUVr) in white and grey matters using MANOVA and discriminant analyses. A cluster analysis on white and grey matter histograms was also performed. Results White matter histogram analysis revealed significant differences between AD and healthy subjects, which were not revealed by SUVr analysis. However, white matter histograms was not decisive to discriminate groups, and indexes based on grey matter only showed better discriminative power than SUVr. The cluster analysis divided our sample in two clusters, showing different uptakes in grey but also in white matter. Conclusion These results demonstrate that AV-45 binding in white matter conveys subtle information not detectable using SUVr approach. Although it is not better than standard SUVr to discriminate AD patients from healthy subjects, this information could reveal white matter modifications. PMID:24573658

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.

  13. A Study of Subseasonal Predictability of the Atmospheric Circulation Low-frequency Modes based on SL-AV forecasts

    2017-04-01

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

    The aim of this study was to make a survey over the physical parameters and how they affect the image quality and the final diagnosis for myocardial perfusion SPECT in Sweden. Another aim was to evaluate the need for standardized acquisition and processing protocols for myocardial perfusion SPECT. All thirty nuclear medicine departments in Sweden that perform myocardial perfusion SPECT participated in the study. A thorax heart phantom was used to simulate two patients. All studies were acquired and processed with the parameters used clinically in each hospital respectively. A quantitative and a qualitative evaluation were performed. At each hospital, the local nuclear medicine physician interpreted the images as if they were true patient images. There are great differences in the acquiring and processing parameters used in myocardial perfusion SPECT studies in Sweden. The image quality varies greatly for the different hospital but was approved for the majority of the hospitals. Images from two hospitals were considered to be too poor to be diagnosed. The interpretations of the local nuclear medicine physicians differ but the majority has reported an adequate diagnosis. One third of the hospitals have reported false positive defects. All steps in the chain from the acquisition to the evaluation of the medicine physician must be performed with high quality. The determinative factors are the noise reduction filter, the orientation of the slices in the heart and the judgement of the local medicine physician. The acquiring and processing parameters proposed by EANM should be used. The hospitals are also recommended to investigate in the time and resources available, in order to educate all staff involved in the evaluation of myocardial studies

    This report considers questions regarding flue gas condensing plants connected to bio-fuelled heat and power plants. The report consists of two parts, one where nine existing plants are described regarding technical issues and regarding the experience from the different plants. Part two is a theoretical study where heat balance calculations are made to show the technical and economical performance in different plant configurations and operating conditions. Initially the different parts in the flue gas condensing plant are described. Tube, plate and scrubber condensers are described briefly. The different types of humidifiers are also described, rotor, cross-stream plate heat exchanger and scrubber. Nine flue gas-condensing plants have been visited. The plants where chosen considering it should be bio-fuel fired plant primarily heat and power plants. Furthermore we tried to get a good dissemination considering plant configuration, supplier, geographical position, operating situation and plant size. The description of the different plants focuses on the flue gas condenser and the belonging components. The fuel, flue gas and condensate composition is described as well as which materials are used in the different parts of the plant. The experience from operating the plants and the reasons of why they decided to chose the actual condenser supplier are reported.

    AV-45 amyloid biomarker is known to show uptake in white matter in patients with Alzheimer's disease (AD), but also in the healthy population. This binding, thought to be of a non-specific lipophilic nature, has not yet been investigated. The aim of this study was to determine the differential pattern of AV-45 binding in white matter in healthy and pathological populations. We recruited 24 patients presenting with AD at an early stage and 17 matched, healthy subjects. We used an optimized positron emission tomography-magnetic resonance imaging (PET-MRI) registration method and an approach based on an intensity histogram using several indices. We compared the results of the intensity histogram analyses with a more canonical approach based on target-to-cerebellum Standard Uptake Value (SUVr) in white and grey matter using MANOVA and discriminant analyses. A cluster analysis on white and grey matter histograms was also performed. White matter histogram analysis revealed significant differences between AD and healthy subjects, which were not revealed by SUVr analysis. However, white matter histograms were not decisive to discriminate groups, and indices based on grey matter only showed better discriminative power than SUVr. The cluster analysis divided our sample into two clusters, showing different uptakes in grey, but also in white matter. These results demonstrate that AV-45 binding in white matter conveys subtle information not detectable using the SUVr approach. Although it is not more efficient than standard SUVr in discriminating AD patients from healthy subjects, this information could reveal white matter modifications. (orig.)

    Hva skal til for å lære av erfaring? Denne avhandlingen er en empirisk baseret undersøkelse av ungdosmskolelæreres muligheter og betingelser for å "lære av erfaring" i den særlige betydning av begrepet  W. Bion gir i sin psykoanalytiske teori. Undersøgelsen baserer seg på et feltarbeid som strekker...... seg over ett skoleår. Datamaterialet ble samlet inn via observerasjoner og mer eller mindre strukturerte samtaler med lærere ved to forskellige norske ungdsomsskoler. Analysen av materialet foregår i to trinn: først en fenomenologisk analyse, tett på lærernes egne beskrivelser og refleksjoner av...... lærerarbeidet, dets udfordringer og vanskeligheter, og deretter en psykoanalytisk perspektivering av de fenomenologiske analyseresultatene. Analysen viser en almindelig lærerhverdag og en skoleorganisation, hvor lærernes "læring av erfaring" i stor utstrekning blokkeres i et vekselspill mellem lærernes flukt...

  3. Vurdering av andrespråksinnlærere - en utfordring i skolen

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

  11. Open absorption heat pump for waste heat utilization in the forest industry. A study of technical and economic potential; Oeppen absorptionsvaermepump foer uppgradering av spillvaerme fraan skogsindustrin. Studie av teknisk och ekonomisk potential

    Waste heat from the forest industry is mainly humid air or humid flue gases with somewhat too low dew point for direct use as district heating or for other qualified purposes. Upgrading of the temperature by heat pumps is thus often necessary for the full use of the waste heat. This study evaluates an open absorption heat, based on hygroscopic condensation. The hygroscopic condenser has the potential to replace mechanical heat pumps or conventional absorption heat pumps (based on lithium bromide) for the upgrading of heat from humid gases. The goal for the project is to evaluate technology and potential for an open absorption heat pump for heat recovery from humid gases in the forest industry. In an open heat pump the humid gas is brought in direct contact with the hygroscopic liquid (whereas a conventional heat pump uses an intermediate circuit with evaporation of water in the evaporator). The direct contact makes it possible to recover the heat at a higher temperature than the dew point of the humid gas without the use of evaporator. The target group for the study is the forest industry and its suppliers of technology and knowledge. The study has been carried out in cooperation with representatives from the forest industry and from suppliers of equipment. The study shows that the forest industry has good potential to upgrade waste heat from humid air to district heating. The waste heat can be extracted from various humid gases such as exit air from paper machines, wood driers, green liquid quenchers and flue gases from soda boilers, mesa kilns, bark-fired boilers and gas engines. Hygroscopic condensation is considered to give economic and environmental advantages compared to conventional absorption heat pumps due to much less consumption of driving heat. An interesting special case is the regeneration of the hygroscopic medium by direct contact with hot flue gases and for this application a patent application has been filed.

    A review of the Oskarshamn 2 Level 2 PSA has been conducted by VTT Processes. One objective of the review was validation and development of Tillsynshandbok PSA applying it to Oskarshamn 2 PSA Level 2 study. The review was based on the PSA Level 2 documentation: the main report, the supporting reports on containment success criteria and release calculations with the MAAP4 code, and five phenomenological reports for selected specific questions. The main result of the phenomenological analyses is that none of the phenomena considered contributes to the conditional failure probability of the Oskarshamn 2 containment in severe accidents. The project was conducted as a set of separate studies and the project quality assurance has also focused on one part at the time. As such, the quality assurance is adequate. A high level QA ensuring that all separate studies and analysis steps use same assumptions seems to be missing. Results from the phenomenology reports are not always transferred to accident analyses and vice versa. There is no specific discussion of uncertainty or sensitivity analyses. In general, the number of sensitivity analyses could be larger. Such should have been provided for sequences or phenomena that could result in early or unmitigated release. Examples are pressure vessel failure at high pressure, the effect of larger hydrogen production, and the key assumptions used for steam explosion and direct containment heating. Suggestions for additional sensitivity studies have been given in discussion of phenomenological reports. The project documentation is generally good. Missing information is usually associated with transfer of results from one study to another. It can be assumed that the information exists also in this cases but has not been documented in the reports above. Documentation of the containment event trees and the assumptions used for them could be more detailed, maybe similar to the approach used in the Appendix of this report. More effort

    Two natural gas fields have been studied for three different technological solutions using two different economic theories. The aim was to examine whether a new technology for transporting natural gas, Natural Gas Hydrates (NGH), can compete with the existing technologies pipeline and Liquefied Natural Gas (LNG). Natural gas can rarely be used immediately after production and the supply systems can be divided into four interrelated parts: 1) Exploration. 2) Development and production. 3) Transportation. 4) Distribution. The emphasis in the study is on production costs and transportation. Exploration is assumed carried out and thus viewed sunk cost. Distribution from landing point to consumers is not part of the study. Production can take place either onshore or offshore, the natural gas can be transported to the market either by pipeline or ship and the costs are becoming more important as the distance from the fields to the markets increase. Natural gas projects have long lead times and large capital requirements. New supplies will materialise then if there is confidence that demand for the gas exists at a profitable price. Therefore natural gas is generally sold on long term contracts. The conclusions are that economies of scale exist and that pipeline is the superior technology for high volumes but cannot compete for smaller volumes where the LNG technology has been the best alternative. However, the report concludes that the NGH can compete fully. The distance to the market where the natural gas is to be transported is crucial for choice of transportation mode. The shipping modes are superior for long transportation distances. NGH is superior to LNG also with regards to distance. Despite that the two economic models used for the evaluation have provided very different absolute project values, they have provided the same conclusions about the ranking of the different technologies. It is clear then that if NGH technology is developed further into a reliable and

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

    2018-06-01

    We study the existence of spacelike graphs for the prescribed mean curvature equation in the Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime. By using a conformal change of variable, this problem is translated into an equivalent problem in the Lorentz-Minkowski spacetime. Then, by using Rabinowitz's global bifurcation method, we obtain the existence and multiplicity of positive solutions for this equation with 0-Dirichlet boundary condition on a ball. Moreover, the global structure of the positive solution set is studied.

    2011-07-01

    Avfall Sverige - Swedish Waste Management's Steering Group for certification of digestate [1] got an inquiry from the biogas industry if the use of polymers as additive in the biogas process is allowed. A requirement according to the certification system is that any additive used must be free from negative effects on the digestate or the soil quality. This study is initiated because of the limited knowledge of how the use of polymers affects the environment. The study is intended to be used as a basis for a decision by the Steering Group concerning the use of polymers in digestate and for an approval by the agri-food industry. The purpose of this study is to gather basic knowledge on the polymers used in dewatering and to identify polymer candidates and analytical methods for further studies of degradation, accumulation and toxicity. The project is limited to include a literature review, a survey concerning the use of polymers at biogas and sewage treatment plants, an impact analysis and a compilation of relevant laws and directives through contacts with authorities. No laboratory or field tests are included in this study. Sewage treatment plants (STPs) were included in the survey as they have been using polymers for dewatering of sewage sludge for many years and therefore should have substantial knowledge about polymers and their environmental effects. According to the literature, the side chains of polyacrylamide (PAM) can be degraded both aerobically and anaerobically. However, the polymer backbone degrades slowly or not at all in the environment, possibly leading to accumulation. Reported effects of PAM on the biogas process are conflicting, showing both inhibitory effects and no effects on the biogas process. Knowledge about the environmental impacts to be expected from spreading polymer amended bio-manure or sewage sludge is limited. The authorities have not handled the issue before and have no further information. Polymer amended sewage sludge has been

    The aim of this study is to describe how peat bogs harvested by deep digging technique can be treated after harvesting has come to an end. The study points out treatment methods, how the treatments are carried out and to indicate the most appropriate method of harvest for optimum results. Costs and benefits are calculated for the methods involving cultivation. The knowledge gained from traditional peat harvesting technique indicate forestry, energy wood production and establishment of ponds as possible alternatives. Energy grass cultivation and establishments of game parks have not been tested. but are assumed to be viable on suitable sites. Establishment of duck ponds are also possible, even though conditions for these are better on firm ground. In this study spruce is estimated to produce 200 cubic meters during 105 year whilst pine produces 300 cubic meters. Calculations for pine and spruce estimate costs of respectively 17000 and 18000 SEK per hectare after 105 years. Energy wood production is estimated to be 11.6 tons dry matter per hectare and year which gives a net cost of 19000 SEK per hectare. Similarly energy grass cultivation results in an average annual harvest of 6.5 ton dry matter and a cost of 59000 SEK per hectare. If the results are applied to three specific cases, then forest cultivation and establishment of ponds are possible in all cases. Neither energy wood nor energy grass are appropriate in any of the three regions. At the particular site for this study all methods mentioned are possible. Depending on whether draining leads to a high or low water table, the most appropriate course would be the establishment of a pond respectively a game park of forest cultivation.

    A segmented market, according to traditional methods, appears increasingly difficult in mature consumer markets. A common explanation is that the mature markets are often characterised by over-supply which results in a great variety of choices for the consumer. Furthermore, the consumer of today has a more complex and flexible purchase behaviour which is difficult to catch. This makes consumer segmentation difficult. International studies indicate that dividing consumers into generation cohor...

    Full Text Available Understanding spirituality and spiritual care for older people – a hermeneutical study In old age, spirituality and existential issues may become salient. The study aim is an understanding of older peoples’ perception of spirituality and spiritual care in a Norwegian context. Gadamer hermeneutics is the guiding methodology. 30 interviews were conducted with 17 participants between 74-96 years, six self-reliant, five with homecare, and six nursing home residents. The findings present understanding of spirituality, soul and spirit, the meaningful in life, inner peace, care from family in old age, and spiritual care. The study discusses spirituality as a force that contributes to wholeness and health, especially by the experience of “inner calm and peace”. That which may contribute to inner peace is love for fellow human beings and being with others, religion and nature, together with meaningful activities and feeling “alive”. Spiritual care involves “to care about” the whole person through compassionate care, presence, listening, touch and facilitating socializing and activities.

    The aim of this project has been to get more knowledge about the impact of noise, shadows and on the view of the landscape from wind turbines. Further to be able to increase the reliability and relevance of the methods used to calculate and evaluate nuisances from wind turbines in applications for wind power development. We have also tried to find other factors that can play a role for the evaluation of wind turbines, if they will be considered as a nuisance or not. The research has focused on a critical review of the methods and regulations that are used in Sweden and other countries, and case studies to find out how people living neighbors with wind turbines will be affected by noise, rotating shadows, visual intrusion and other factors. This report includes the case studies of wind turbine areas at Gotland. Three different areas on the island Gotland in the Baltic Sea, with wind turbines in the close neighborhood, were chosen for case studies: Naer, Klintehamn, Naesudden. In these places only persons who live close to wind turbines have been interviewed; in Nar all who live within 1100 meters from two large wind turbines, in Klintehamn a sample of those who live ESE of the turbines and get shadow flicker from them during sunset, and on Naesudden those households that live in the middle of a large wind farm with 81 turbines. In total 94 persons in 69 households have been interviewed. The acceptance of wind power among people living as close neighbors is quite high. However, the nuisance and annoyance can be reduced further, if the recommended values for noise immission etc are applied correctly. To do that the ability of project developers and authorities that grant permissions to evaluate the calculated immission has to be raised, since specialist competence and experience is necessary to do predictions of actual immission from the models used for calculations. The recommended minimum distances between wind turbines and houses that some communities have

    Full Text Available This study reviews research publications topically related to day centres for people with mental health problems. The purposes are to give a general overview of the evidence-based knowledge in the field, to detect gaps of knowledge, and to throw light on the following research questions: (1 Which ideologies about day centres may be revealed in Scandinavian- and English-speaking research on day centres for people with mental health problems; and (2 What significance do the day centres have for the users? Both questions are answered by examining 34 research publications, printed in either Scandinavian or English languages during the period 1962-2015. An integrative literature review was used as method. The topical knowledge revealed is categorized under two headings: (a the day centres’ organization, and (b their materiality and internal life. The results and the discussion show that the day centres in the 1960s started out as arenas based on treatment ideology, dominated by psychiatric, medical knowledge. Slowly and gradually the ideology changed towards recovery approaches. However, this change in ideology does not mean that the day centres have succeeded in implementing the idea of integrating the users in the general society.

    The year 2011 marked the 80th anniversary of Georges Lemaître’s primeval atom model of the universe, forerunner of the modern day Big Bang theory. Prompted by this momentous anniversary the Royal Astronomical Society decided to publish a volume of essays on the life, work and faith of this great cosmologist, who was also a Roman Catholic priest. The papers presented in this book examine in detail the historical, cosmological, philosophical and theological issues surrounding the development of the Big Bang theory from its beginnings in the pioneering work of Lemaître through to the modern day. This book offers the best account in English of Lemaître’s life and work. It will be appreciated by professionals and graduate students interested in the history of cosmology.

    In order to appreciate the contribution which Georges Lemaître made to the relationship between religion and science it is necessary to understand how the Catholic Church, of which he was a priest, passed in the course of three centuries, from a position of conflict with the sciences to one of compatible openness and dialogue. In doing this I hope to show that the natural sciences have played a significant role in helping to establish the kind of dialogue that is absolutely necessary for the enrichment of the multifaceted aspects of human culture. I will speak of the following four periods of history: (l) the rise of modern atheism in the seventeenth and eighteenth centuries; (2) anticlericalism in Europe in the nineteenth century; (3) the awakening within the Catholic Church to modern science in the first six decades of the twentieth century; (4) the Church's view today.

Hva predikerer at urbane mennesker angrer på noe de har sagt eller gjort, kommer opp i krangel ellerhavner i slåsskamp under alkoholpåvirkning, og er det forskjeller i så henseende mellom de som er mye og liteeksponert for andre mennesker når de drikker? I det såkalte kafégjestmaterialet ble data innhentet ved hjelp avspørreskjemaer besvart av 1053 gjester på 41 offentlige skjenkesteder i Oslo. I tillegg er det benyttet data fra etrepresentativt utvalg av 297 personer i Oslo (Osloutvalget. Resultatene viste at andelen som rapporterte negativeerfaringer i samband med eget alkoholbruk var høyere i kafégjestmaterialet enn i Osloutvalget. I beggematerialene rapporterte yngre respondenter oftere enn eldre at de hadde angret på noe de hadde sagt eller gjort,kranglet med noen og kommet opp i slagsmål. Å angre på noe sagt eller gjort hadde ingen sammenheng medantallet timer tilbrakt ukentlig på kaféer i materialene. Blant kafégjestene, men ikke blant Oslofolk generelt, haddeantall timer tilbrakt ukentlig på kaféer sammenheng med å ha kranglet og å ha slåss med noen i en drikkesituasjon.Å havne i slåsskamp eller håndgripeligheter hadde sammenheng med antallet timer tilbrakt ukentlig på kaféer ibegge materialene. Korrelasjonen mellom antall dager med hardere drikkeepisoder på kafé, og antall timerukentlig på kafé, var sterk både i Osloutvalget og i kafégjestmaterialet. Det er sannsynlig at det er harderedrikking på utesteder som er avgjørende for å krangle eller slåss med noen i beruset tilstand, og ikke det åtilbringe tid på utesteder per se. Dette tyder på at større offentlig innsats for å kontrollere at de bestemmelsenesom gjelder for offentlig skjenking av alkohol overholdes, kan redusere voldsnivået på skjenkestedene.Træen B. What influences quarrelling and fighting in

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

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

    The Norwegian Petroleum Directorate (NPD) is the main administrative body with responsibility to regulate and control the safety aspects of drilling for and production of petroleum on the Norwegian Continental Shelf. Its responsibility does not, however, include the aspects of maritime safety, which are regulated by the Norwegian Maritime Directorate. This study is limited to the regulation of safety on fixed installations for production of petroleum. The object has been to describe the methods applied by the NPD to achieve better safety, and to give answers to why these specific methods of approach have developed as they have. A conclusion that may be drawn from this study is that there exists a relationship of close cooperation between the NPD and the oil industry represented by the operating companies. Only this can explain the differences we find in the NPD approach as compared to the approach of other parts of public administration. Such a relationship probably leads to better safety within the scope of technical rationality than would have a more hostile relationship between the Directorate and the industry. This has its price, however. Aspects of the safety question not included within the limits of a purely technical approach are not as easily taken into account. Partly due to this fact, other parties with interests in safety are not represented.

    We study the validity of the Newtonian description of cosmological perturbations using the Lemaître model, an exact spherically symmetric solution of Einstein's equation. This problem has been investigated in the past for the case of a dust fluid. Here, we extend the previous analysis to the more general case of a fluid with non-negligible pressure, and, for the numerical examples, we consider the case of radiation (P=ρ/3). We find that, even when the density contrast has a nonlinear amplitude, the Newtonian description of the cosmological perturbations using the gravitational potential ψ and the curvature potential φ is valid as long as we consider sub-horizon inhomogeneities. However, the relation ψ+φ=O(φ{sup 2})—which holds for the case of a dust fluid—is not valid for a relativistic fluid, and an effective anisotropic stress is generated. This demonstrates the usefulness of the Lemaître model which allows us to study in an exact nonlinear fashion the onset of anisotropic stress in fluids with non-negligible pressure. We show that this happens when the characteristic scale of the inhomogeneity is smaller than the sound horizon and that the deviation is caused by the nonlinear effect of the fluid's fast motion. We also find that ψ+φ= [O(φ{sup 2}),O(c{sub s}{sup 2φ} δ)] for an inhomogeneity with density contrast δ whose characteristic scale is smaller than the sound horizon, unless w is close to −1, where w and c{sub s} are the equation of state parameter and the sound speed of the fluid, respectively. On the other hand, we expect ψ+φ=O(φ{sup 2}) to hold for an inhomogeneity whose characteristic scale is larger than the sound horizon, unless the amplitude of the inhomogeneity is large and w is close to −1.

    2014-07-01

    Full Text Available Tre parole-chiave offrono lo spunto per un’immersione nel pensiero e nell’opera di Giuseppe Pontiggia. La prima: parola, riaffermata dallo scrittore in quanto atto civile e ‘corporeo’ mediante il quale l’uomo fa esperienza di se stesso entrando in contatto con i suoi simili e con il circostante, ricongiungendosi insieme alla sua più profonda e antica natura. Viene così restituita allo scrittore/critico la responsabilità di lottare contro l’attuale minaccia dello svuotamento linguistico, nel nome di una costruttiva utopia culturale. La seconda parola, musica, serve a illuminare i romanzi di Pontiggia – in specie La grande sera e L’arte della fuga – attraverso suggestive analogie con la musica classica e il jazz, predilette dallo scrittore. Ossimoro è l’ultima voce di questo Lexicon: figura retorica, ma soprattutto figura conoscitiva che permette allo scrittore di scoprire la propria verità e il proprio linguaggio e al lettore di abbracciare una visione non lineare e problematica del mondo, capace di ampliare le prospettive e rinnovare lo sguardo.

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

    Full Text Available In most organisms, germ cells are formed distant from the somatic part of the gonad and thus have to migrate along and through a variety of tissues to reach the gonad. Transepithelial migration through the posterior midgut (PMG is the first active step during Drosophila germ cell migration. Here we report the identification of a novel G protein-coupled receptor (GPCR, Tre1, that is essential for this migration step. Maternal tre1 RNA is localized to germ cells, and tre1 is required cell autonomously in germ cells. In tre1 mutant embryos, most germ cells do not exit the PMG. The few germ cells that do leave the midgut early migrate normally to the gonad, suggesting that this gene is specifically required for transepithelial migration and that mutant germ cells are still able to recognize other guidance cues. Additionally, inhibiting small Rho GTPases in germ cells affects transepithelial migration, suggesting that Tre1 signals through Rho1. We propose that Tre1 acts in a manner similar to chemokine receptors required during transepithelial migration of leukocytes, implying an evolutionarily conserved mechanism of transepithelial migration. Recently, the chemokine receptor CXCR4 was shown to direct migration in vertebrate germ cells. Thus, germ cells may more generally use GPCR signaling to navigate the embryo toward their target.

  2. The role of Tre6P and SnRK1 in maize early kernel development and events leading to stress-induced kernel abortion.

    Drought stress during flowering is a major contributor to yield loss in maize. Genetic and biotechnological improvement in yield sustainability requires an understanding of the mechanisms underpinning yield loss. Sucrose starvation has been proposed as the cause for kernel abortion; however, potential targets for genetic improvement have not been identified. Field and greenhouse drought studies with maize are expensive and it can be difficult to reproduce results; therefore, an in vitro kernel culture method is presented as a proxy for drought stress occurring at the time of flowering in maize (3 days after pollination). This method is used to focus on the effects of drought on kernel metabolism, and the role of trehalose 6-phosphate (Tre6P) and the sucrose non-fermenting-1-related kinase (SnRK1) as potential regulators of this response. A precipitous drop in Tre6P is observed during the first two hours after removing the kernels from the plant, and the resulting changes in transcript abundance are indicative of an activation of SnRK1, and an immediate shift from anabolism to catabolism. Once Tre6P levels are depleted to below 1 nmol∙g -1 FW in the kernel, SnRK1 remained active throughout the 96 h experiment, regardless of the presence or absence of sucrose in the medium. Recovery on sucrose enriched medium results in the restoration of sucrose synthesis and glycolysis. Biosynthetic processes including the citric acid cycle and protein and starch synthesis are inhibited by excision, and do not recover even after the re-addition of sucrose. It is also observed that excision induces the transcription of the sugar transporters SUT1 and SWEET1, the sucrose hydrolyzing enzymes CELL WALL INVERTASE 2 (INCW2) and SUCROSE SYNTHASE 1 (SUSY1), the class II TREHALOSE PHOSPHATE SYNTHASES (TPS), TREHALASE (TRE), and TREHALOSE PHOSPHATE PHOSPHATASE (ZmTPPA.3), previously shown to enhance drought tolerance (Nuccio et al., Nat Biotechnol (October 2014):1-13, 2015).

    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

Finite element simulations of the creep behaviour of X20 welds where effects of HAZ creep properties, system stresses and degree of multiaxiality in the rupture criterion are studied. In addition a literature study on publications of creep life time in X20 steel was performed in a first, already reported part of the project. The results of the comprehensive replica testing and the metallographic investigations show clear-cut that welds of this material have an excellently long creep life that indeed will reach 200,000 h. The creep damage at that time is in general very limited. The typical creep life for welds of X20 can be evaluated to at least 250,000 h. The reason for that it is not possible to evaluate an even longer creep life is the fact that creep testing and finite element simulations show that creep elongation and creep damage will accelerate considerably later in the creep life than some low alloy steels. In the worst case this acceleration could start already just after 200,000 h. It is also demonstrated that welds of the X20 steel can stand system stresses much better than low alloy steels. Recommendations for how and when inspections and testing of welds of the current material should be performed have been issued. They have been adapted to the findings in the project. The recommendations can, as long as severe damage is absent, allow for longer inspection intervals

  10. Georges Lemaître: The Priest Who Invented the Big Bang

    Science.gov (United States)

    Lambert, Dominique

    This contribution gives a concise survey of Georges Lemaître works and life, shedding some light on less-known aspects. Lemaître is a Belgian catholic priest who gave for the first time in 1927 the explanation of the Hubble law and who proposed in 1931 the "Primeval Atom Hypothesis", considered as the first step towards the Big Bang cosmology. But the scientific work of Lemaître goes far beyond Physical Cosmology. Indeed, he contributed also to the theory of Cosmis Rays, to the Spinor theory, to Analytical mechanics (regularization of 3- Bodies problem), to Numerical Analysis (Fast Fourier Transform), to Computer Science (he introduced and programmed the first computer of Louvain),… Lemaître took part to the "Science and Faith" debate. He defended a position that has some analogy with the NOMA principle, making a sharp distinction between what he called the "two paths to Truth" (a scientific one and a theological one). In particular, he never made a confusion between the theological concept of "creation" and the scientific notion of "natural beginning" (initial singularity). Lemaître was deeply rooted in his faith and sacerdotal vocation. Remaining a secular priest, he belonged to a community of priests called "The Friends of Jesus", characterized by a deep spirituality and special vows (for example the vow of poverty). He had also an apostolic activity amongst Chinese students.

  11. La marâtre dans les contes merveilleux du Yémen

    2010-07-01

    Full Text Available La figure de la marâtre est particulièrement répandue dans les contes merveilleux du Yémen. Comme en Europe, ce genre de la littérature orale remplit des fonctions d’éducation enfantine, mais il s’adresse aussi aux adultes. Au Yémen, la figure de la marâtre doit être remise dans son contexte socio-économique des familles recomposées dans une société encore rurale et patriarcale. Sans négliger le contexte de performance du conte au Yémen, ni l’intertextualité des différentes formes de contes (se rapprochant du mythe et de l’histoire de ruse, la présentation et l’analyse de cinq contes yéménites et de diverses variantes permettent d’explorer les thèmes fantasmatiques de la mère cruelle et de la monstruosité des autres membres de la famille nucléaire. D’un autre côté, inséparables du merveilleux, les agents magiques sont principalement des animaux qui symbolisent et idéalisent des degrés de parenté proche. Tout en déformant les enjeux de la vie réelle dans un sens moral, le conte yéménite révèle, par ses structures symboliques, l’existence de ce que l’on peut appeler le « complexe anthropologique » de la marâtre, et qui s’exprime aussi, au Yémen, sous d’autres formes littéraires orales qui restent encore à explorer.The literary figure of the stepmother is widely spread in the fairy tales in Yemen. Like in Europe, this genre fulfils educative functions for the children, but it is also addressed to adults. In Yemen, the figure of the stepmother must be put in perspective in the socio-economical context of recomposed families in a still rural and patriarchal society. Without neglecting the performance context of the narration, neither the intertextual weaving of different forms of “tales” (myths, tricksters tales, the presentation and the analysis of five Yemeni tales and their variants allows us to explore the fantasy themes of the cruel mother and other kinds of monstrous kinship

  12. Are acid volatile sulfides (AVS) important trace metals sinks in semi-arid mangroves?

    2018-01-01

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

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

    2013-03-01

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

    In the track of ever-expanding new infrastructure, such as wind power, roads and power lines, it becomes increasingly important to map and understand how free-ranging animals and wildlife respond. During the past decades, human - rangifer interactions have been assessed in over a hundred studies, with a strong bias on wild reindeer and caribou, although more recently also studies on domesticated reindeer in Norway, Finland, Sweden and Russia have been done with similar results. To clarify further the possible responses of domesticated reindeer to various disturbance sources, a review was made of over 15 existing disturbance studies of domesticated reindeer, we also discuss the effect of domestication on reindeer. The review shows the same pattern of avoidance in domesticated reindeer as for wild reindeer and caribou despite the domestication process. Sami reindeer husbandry today is an extensive form of pastoralism, which has led to a low degree of tameness among the reindeer. Domesticated reindeer can avoid infrastructure and human activity up to 12 km from the disturbance source and the avoided distance may shift between seasons and years and type of disturbance source, as well as diminish during periods of extreme starvation or insect harassment, similar to observation in wild reindeer and caribou. To get an overall picture of how the reindeer use their grazing land, it is therefore important to study large-scale and long-term habitat use of the reindeer whether they are domesticated or not. In this report, we want to share new information on how existing infrastructure such as roads and power lines in the landscape and construction phase of a new infrastructure for a wind farm affects the free roaming of the reindeer in a summer grazing area in a managed forest in northern Sweden.

    Full Text Available A philosophical study of the concept of the principle was conducted by Stanislas Breton inhis two books: Du principe and Être, Monde Imaginaire, the first of which was dominated byits analytical and abstract style, while the second was speculative and imaginary. This articleundertakes the task of reconstructing the idea of the principle contained in the latter position.In the first part of the article the author presents two currents of thought concerning theprinciple: the ontological, which is based on the category of logos, and the ontomythological,for which the leading category is mythos. After discussing the differences between these twofields of thought and their corresponding fields of being, the author undertakes an attempt atdescribing the absolute source of reality – imaginary-nothing. The attempt is accompanied bya presentation of the way in which the ineffable principle produces the Word, whose originalexpression is prattle. The article concludes with an analysis of fable as the original form of expressionof the imaginary-nothing, from which arise the two trunks of rationality mentionedabove: the ontological and the ontomythological.

    Heating comprise the major part of the cost of supporting a building with necessities like electricity, heat, refuse collection and water and sewage. As these costs increase, it is becoming more interesting to find other solutions in order to reduce them. One alternative is to convert to another heating system. Several price analyses comparing different heating systems have been performed. Avgiftsgruppen publishes one report on a yearly basis, where the costs to support a building with necessities and how they vary between communities are listed. The latest report states that it is less expensive in 75 % of the communities in Sweden to convert from district heating to a pellets boiler or a ground-source pump. However, other studies have established that the heat market is a local market with local conditions. Therefore you need to compare alternative heating costs that are specific to the area instead of estimated average costs at a national level. The purpose of this survey is to study a local heat market in order to verify the real cost of the alternative heating systems to district heating and if these costs vary between different communities. The hypothesis is that it is not possible to generalize the heating cost on a national level. Instead, a local market should be studied to make an accurate cost comparison between heating options. Three communities are studied in order to find real and verified investment costs in pellet boilers and heat pumps. The investments that are of primary interest are those performed in buildings similar to the multi-dwelling house used in earlier price analyses. Furthermore, the building should be located within the distribution network of district heating in order to illustrate the competition between the heating alternatives. The result of the study illustrates the difficulties to find real and verified costs of completed investments in alternative heating systems in buildings that is of primary interest for this study.

    Energy Performance Contracting (EPC) is an energy service which means that investments in energy saving measures are financed by means of guarantied energy savings. Since the measures are financed by estimated savings, an overall perspective on the energy performance, operating costs and indoor climate of a building or a whole building complex becomes possible. EPC thereby provides a possibility to more far-reaching energy saving measures which would otherwise not be tolerated within the operating budget. The environmental benefit such as reduced climate impact, can in some cases even be the overall objective and energy saving a way to achieve that objective. This study has investigated four EPC projects performed by public organisations in Sweden. The aim has been to analyse to what extent environmental benefit is a decision parameter in the EPC process and to develop a method and a calculating tool that make it possible for different EPC suppliers to use a common method to show the environmental benefit of the energy saving measure. Our main conclusion from this study is that the environmental issue is an important part of a EPC project but it can not be considered to be a well-functioning decision parameter. Today other parameters such as maintenance needs, modernisation, indoor climate and cost savings are the most important at the early stage for the employee of the public organisation. However, the environmental benefit could be highlighted already at this stage to show that those other advantages can be achieved with higher or lower environmental benefit, and to make sure that the political environmental benefit becomes a more important factor in the procurement process (after a political decision). An experience from the study is that for the environmental issue to play a mayor role in the realisation of an EPC project it must be involved already before the decision to perform an EPC project. This is true specially if the supplier are expected to optimise

    The use of recovered wood based fuels sometimes leads to a substantial increase in the rate of corrosion with outages and increase in maintenance costs as a consequence. Therefore, Vaermeforsk has financed two framework programmes on recovered wood based fuels. All results, except those from thermodynamical calculations, support the conclusion that enhanced levels of zinc and chlorine is one of the most important reasons for the development of harmful deposits. The system zinc chloride - potassium chloride contains several intermediate phases, out of which K{sub 2}ZnCl{sub 4} has a considerably higher melting point compared to pure zinc chloride. This provides ground for the suspicion that there may be synergetic effects between potassium and zinc and that condensation from the gas phase therefore might take place at a temperature which is higher than that which has been reported earlier. The purpose of the present study is to investigate the correctness of this hypothesis by means of thermodynamical calculations. As a first step, the energy of the intermediate phase K{sub 2}ZnCl{sub 4} was modelled utilizing results from electrochemical measurements in salt melt. The thermodynamical calculations were conducted using software which had been developed by BeN Systems including a dedicated database. Thus, all calculations have been carried out independently of those performed previously. In order to ensure full comparability, some calculations were carried out using the same input parameters as used previously and the results were essentially identical. After this, thermodynamical calculations were carried out using a database which included the intermediate phase K{sub 2}ZnCl{sub 4}. The results show that the influence of this phase corresponds to an increase in condensation temperature for zinc chloride with more than 200 deg C. A prerequisite for the formation of this phase is that the amount of available chlorine exceeds that of potassium. Similar effects can be

    The energy and environmental council of the Royal Swedish Academy of Engineering Sciences initiated this study of how an additional 30 TWh/year of forest biofuel could be used in the Swedish energy system within a 10-year period. The specifications include that the forest biofuel shall be used in such a manner that the greatest possible reduction in carbon dioxide emissions will be achieved at the lowest cost without risking other environmental goals, such as good quality of local air. The figure chosen as starting point for the study, 30 TWh/year, was selected as it is this amount that available data have suggested could be extracted without negatively affecting the long-term productive capacity of forest land. The long-term potential of biofuel will probably be much larger than the volume used today, together with the additional use of 30 TWh/yr. We therefore studied fields of use that, totally, will be considerably larger than 30 TWh/yr. The starting point for comparisons of different uses for forest biofuel was the available benefit/utility for industrial, transportation and service sectors, together with domestic uses. The reference alternative was the existing uses of fossil fuels. Comparisons of different alternatives were made including differences in fuel consumption, CO{sub 2} emissions, emissions of sulfur dioxide, nitrogen oxides and dust, as well as costs without environmental and energy taxes or subsidies. Monetary estimations of sulfur dioxide, nitrogen oxides and dust in accordance with the EU ExternE Project were included in the costs. In our study, we have used two scenarios as starting points in order to cover the range of results. Summary of results: The largest reductions in CO{sub 2} emissions (generally about 0.6-1 Mtonnes CO{sub 2} /TWh forest biofuel and for heat pumps slightly more than 2 Mtonnes CO{sub 2}/TWh forest fuel) at the lowest cost are obtained when bioenergy replaces electricity produced by coal fired condensing power stations

    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%.

    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 Abstract: This article is based on the study of the project: “Ergonomics and pedagogics hand in hand – health in every movement” (EPH and the implementation of it in a Norwegian kindergarten. A central idea in the EPH- project is that by focusing on children’s motor development, and allowing them to be more independent in daily activities, ergonomic benefits that will ease employees' workday will be achieved. Our study of this project is inspired by Bruno Latour's perspectives on the relation between humans and materiality and the data is sampled by field observations. The main question we rise and discuss in the article is: What tensions might arise when ideals to benefit both children’s independency and the employer’s ergonomic health are to be implemented simultaneously in a kindergarten context? Overall, the results of the study shows that the tension between children’s attempt to be independent, on the one hand, and the adult’s’ tendency to strive for tidiness and security, on the other, is significant. This can partly be explained by that humans may interact differently with a given materiality than the original purpose of it was. Physical environments may also invite for multiple ways of using it and thus the very same material organization may promote as well as constrain a good synergy between ergonomic and pedagogic ideals. We therefore conclude that to fulfill both children’s and adult’s needs at the same time, in the specific material space a modern kindergarten represents, might imply some very distinct challenges that planners and users should take into account.

    2016-12-01

    Being Students of Teacher Researcher Experiences (SoTRE) gives students special advantages that most students do not get. Teachers Elizabeth Eubanks and Steve Allen share their knowledge gained via partnerships with Teacher Researcher Experiences (TRE's) such as the National Oceanographic and Atmospheric Administration Teacher at Sea program (NOAA- TAS), Polar TREC (Teachers and Researchers & Exploring & Collaboration), National Science Foundation (NSF) funded researchers, (EARTH) Education and Research: Testing Hypothesis, the RJ Dunlap Marine Conservation Program, C-DEBI (Center for Dark Energy Biosphere Investigations and (STARS) Sending Teachers Aboard Research Ships, The Maury Project and Mate. Students gain special privileges such as understanding unique research ideas, tracking tagged sharks, following daily journals written on location, taking part in cross-continental experiments, tracking real time data, exploring current research via posters or visiting universities. Furthermore, contacts made by a TRE give students an added set of resources. When doing experiments for class or advancing their education or career goals Eubanks and Allen help students connect with scientists. Many students have felt so strongly about the TRE relationship that they have presented at several local and international science conferences. Their message is to encourage scientists to partner with teachers. The benefits of participation in such conferences have included abstract writing and submission, travel, poster creation, oral presentation, networking and personal research presentation, all tools that they will carry with them for a lifetime.

  13. Lemaître, the Big Bang and the Quantum Universe

    Science.gov (United States)

    Heller, Michael

    Lemaître's work on the geometric nature of singularities and his speculations concerning the applications of quantum physics to cosmology are confronted with later achievements in these fields. His works on the global structure of the de Sitter solution and the appearance of "non-regular" points in the Schwarzschild solution led to the conclusion that the "vanishing of the radius of the universe" is a generic property of cosmological models. This conclusion was strengthened when Lemaître proved that, against Einstein's intuition, space anisotropy (in Bianchi I models) does not remove the singularity. This is why Lemaître regarded the initial singularity as a "geometric support" of his Primeval Atom hypothesis. This hypothesis was not yet a quantum gravity idea (in the present sense of this expression), but it was certainly an application of quantum physics to the early stages of cosmic evolution. The beginning itself is aspatial and atemporal, and both space and time emerge only when the simplicity of the Primeval Atom gives place to physical multiplicity. How do the problems with which Lemaître struggled appear in the light of the present state of cosmological research?

  17. Fractional order absolute vibration suppression (AVS) controllers

    Science.gov (United States)

    Halevi, Yoram

    2017-04-01

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

  18. Sampling method, storage and pretreatment of sediment affect AVS concentrations with consequences for bioassay responses.

    2008-01-01

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

  3. Open-Loop Audio-Visual Stimulation (AVS): A Useful Tool for Management of Insomnia?

    Science.gov (United States)

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

    2016-03-01

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

  6. Georges Lemaître and Fred Hoyle: Contrasting Characters in Science and Religion

    Science.gov (United States)

    Holder, Rodney D.

    Georges Lemaître was a jocular Roman Catholic priest and Fred Hoyle a bluff Yorkshireman who despised organized religion. Both were giants of twentieth century cosmology but espoused diametrically opposed cosmological models. This paper explores the extent to which ideology, and particularly religion, played a part in the controversies over the big bang and steady-state theories. A particular problem for many cosmologists, including Hoyle, was posed by the idea that the universe had a temporal beginning: an eternal, unchanging universe seemed metaphysically preferable. And Hoyle was highly polemical about religion in his popular writings. In contrast, Lemaître saw no theological import from the big bang, and never entered a debate about its theological implications until, perhaps unexpectedly, he took issue with an address given by the Pope. Hoyle's seminal work on stellar nucleosynthesis led him to speak of a `superintellect monkeying with physics' though this was never identified with the God of classical theism. The work of both Lemaître and Hoyle resonates with more recent debates concerning cosmology.

    The Center for Promotion of Computational Science and Engineering of the Japan Atomic Energy Research Institute has carried out the ITBL (Information-Technology Based Laboratory) project which is one of e-Japan priority policy programs. The goal of the ITBL project is to create the vertical research environment in which intellectual resources such as remote computers, programs and data can be shared in Japanese research institutions and cooperative studies among researchers can be supported. AVS/ITBL is the visualization tool which has been developed aiming at realizing the efficient visualization in the ITBL environment. This visualization tool is one of the tools of ITBL infrastructure software and operates in cooperation with AVS/Express. Main functions of AVS/ITBL are as follows: it can directly read data files located on remote computers, it can display and control an image on the web browser, it can collaboratively display an image among remote researchers, and it can perform visualization process as a batch. In this paper, utilization of AVS/ITBL to the numerical environmental system, which is one of the applications in ITBL project, is presented. And the outline of the operation in this utilization is indicated. (author)

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

    1994-09-01

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

  12. Examination of office visit patient preferences for the after-visit summary (AVS).

    Neuberger, Marolee; Dontje, Katherine; Holzman, Greg; Corser, Bill; Keskimaki, Abigail; Chant, Ericka

    2014-01-01

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

Furthermore, in those cases where more than one food company has pointed at a particular competence as a distinctive competence, it is evident that the companies have structured the competence very differently. This also indicates that there is "room" for building up a particular competence in different ways...... and still - or rather therefore - be successful with the competence. 4.

    Greenhouse gas emissions from building linked today to a large extent to the energy consumption during the operating period. Through increasingly stringent energy requirements and other changes, the energy consumption for the operation could go down over time. This means in this case that the energy required to produce, transport and set up the building, to a greater extent can be relatively more important in a life-cycle analysis. KRD in that regard ha given Oestfoldforskning the commission to conduct a literature study that will provide an overview and assessment of the literature / research papers describing various building materials climate impact and how this translates into a lifetime (LCA - Life Cycle Assessment), and thus describe the knowledge platform these analyzes are based in. It also means a description of the factors that affect the climate and the environment, including the stages of life that are important. Literature study is conducted by searching scientific databases (Springer Link, Science Direct, Google Scholar, Norwegian EPD database of declarations).

Based on the review of literature is also undertaken an analysis focusing on explaining the methodological platform between the studies are based on, in order to explain why the results differ and / or may not be comparable.(eb)

    The pilot study was initiated by the need of a new technology that has been raised from the problem, and by the specifications of requirements, that has been described from the project 'Salix Maelardalen'. The need has been crystallized by the energy company Maelarenergi AB, Vaesteraas, in their handling of bio fuel, among many other fuels. The company Maelarenergi AB can see a potential in the use of Salix of a considerable volume. There is a special need by the means of the big volume handling of Salix, since the Salix raw material must be able to be delivered under a longer period or for intermediate storage. 8-9 months could be an adequate storage period. The possibility for intermediate storage could do the flow of fuel raw material to the combined power and heating plant is harmonized to the special requirements of fuel. The storage capability in chipped raw Salix chips is very short and that's why chipped Salix are not going to be a sustainable system combined with the handle of big volume together with portioned inflow to the plant. The production of Salix chips in a system of direct chipping is a very delicate system. The ground conditions with frozen and dry grounds are important for a system with heavy machines. The last years have not given such climate conditions. A big problem with practicability has been coming up. The number of days for contract work during the harvest period without interruption, because of hard conditions, has been decreased to the level that the capacity very considerably falls below what is economical defensible. The needs of larger areas for harvesting during fewer days under good conditions counteract each other. In the 'hot flow' during the harvest when the harvest machine will work with escort vehicles/container transports in the field can be impossible to realize because of for example the breakdown of the soil structure. The organization around 'hot flow system' is a very heavy programme

    Full Text Available This study explores primary school students’ abilities to recall events from a teaching sequence taking place 18 months earlier. The aim of the teaching sequence was to develop students’ ability to read nature in a river habitat. The concept reading nature has to do with an ability to recognise organisms and relate them to material cycling and energy flow in the specific habitat which is to be read. In this study the aim is to analyse the episodes the students recall in order to find patterns in students’ views of memorable learning events. Combining the affective and cognitive domains by first hand experiences which challenge students’ everyday conceptions and to involve them in the design of the activities make lasting impressions in the long term memories of the majority of students. These memorable episodes can be useful to relate to in the further classroom teaching about the content knowledge of science in order to make it more meaningful for the students.

  10. Inter-Dye Distance Distributions Studied by a Combination of Single-Molecule FRET-Filtered Lifetime Measurements and a Weighted Accessible Volume (wAV Algorithm

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Förster resonance energy transfer (FRET is an important tool for studying the structural and dynamical properties of biomolecules. The fact that both the internal dynamics of the biomolecule and the movements of the biomolecule-attached dyes can occur on similar timescales of nanoseconds is an inherent problem in FRET studies. By performing single-molecule FRET-filtered lifetime measurements, we are able to characterize the amplitude of the motions of fluorescent probes attached to double-stranded DNA standards by means of flexible linkers. With respect to previously proposed experimental approaches, we improved the precision and the accuracy of the inter-dye distance distribution parameters by filtering out the donor-only population with pulsed interleaved excitation. A coarse-grained model is employed to reproduce the experimentally determined inter-dye distance distributions. This approach can easily be extended to intrinsically flexible proteins allowing, under certain conditions, to decouple the macromolecule amplitude of motions from the contribution of the dye linkers.

    2009-07-01

    The overall aim of this pre-study is to contribute to an increased co-handling of biomass from forest and field at terminal and railway transport, in order to find effective transport solutions with regard to costs and environment. The aim of the pre-study is also to get an overall picture of transport of biomass on railway. The objective is to draw conclusions of use for interested parties within the agricultural sector, on what possibilities there are to handle biomass from forestry and agriculture with the same logistical infrastructure. Conclusions are drawn especially with regard to Short Rotation Willow Crops (here Salix) handled as chips or bundles, but also briefly for other energy crops suitable for combustion. Furthermore, the study draws conclusions on how to design effective terminals and related costs. The pre-study is intended as a planning material for a more in-depth study of a mobile terminal solution, with active participation from interested players in the agricultural sector. When considering railway transport and terminal transhipment of large volumes of biomass, there is a clear economical benefit in designing large terminals and making investments in effective handling equipment, in order to get a high use of equipment and a high storage turnover. A more simple and temporary terminal solution may be suitable for smaller flows of biomass, such as agricultural fuels, which need to be collected in different areas according to availability. An intermodal solution, i.e. which involves the transportation of freight in the same type of carrier (a container for example) when changing modes of transportation, is suitable for this purpose. The solution should also build on standardised equipment, involve low terminal investments and flexible and temporary transhipment in different areas near the location of the biomass. For railway transport, the same handling equipment may be used for wood chips and Salix chips, i.e. standardised container systems

    The largest energy demands in connection with the operation of bag house filters are the electric energy consumption for the fans, securing the flow of flue gas through the filter, and the electric energy consumption when producing the pressurized air (compressors or high pressure fans). Considering the significantly increased fan work when having a non-optimised cleaning of the filters, it seems justified to investigate the possibilities to minimise the unnecessary pressure drop. There is also a saving potential in the filter cleaning process, which otherwise may cost an unacceptable amount of pressurized air or other energy. The main purpose of this work is to develop methods to optimize the operation of bag house filters, which is started up with this report containing a follow-up of what has been done in Denmark and a confirmation of the technology status. In the next step, a case study where two-three plants are examined more in detail is suggested followed by a potential study to estimate the total energy saving potential in Sweden. Dust precipitation with bag house filters is basically a rather simple technique, which has existed in flue gas cleaning for about 50 years. From the literature study it can be established that there has been no revolutionary development in the field, but there are some work being done mainly to introduce new filter material but also to optimise the use of bag house filters with new computer based control systems. The largest potential of energy saving prevails if the filter from the beginning is overloaded, which usually is the case. The reason for overload may be a too large volume flow in relation to the filter area, that the dust has penetrated and blocked the filter, a defective filter cleaning process or that wrong filter material has been chosen. In Denmark a study has been made with the purpose to investigate the possibilities to optimise the energy consumption for bag house filters. For the three plants studied, an

På grunn av detlave prisnivået for alkohol er ulovlig import eller hjemmeproduksjon av alkohol ukjent på Svalbard. Dessutener samfunnet lite og oversiktlig, slik at det er praktisk mulig å undersøke hele befolkningen. I den aktuellestudien registrerte vi alt salg av alkohol til fastboende nordmenn på Svalbard i oktober og november 1988. Isamme tidsperiode ble alle nordmenn 18 år eller eldre invitert til å ta del i en helseundersøkelse der det inngikkspørsmål om alkoholbruk.

No counterfeit production or illegal import exists, thus making a complete registrationof all sources of alcohol possible. In this study we recorded sales from all agencies selling alcohol onSvalbard over a two month period in 1988. During the same period all adults living permanently on Svalbardwere invited to take part in a health screening. As part of the screening a self-administered questionnaire onalcohol consumption was introduced to the participants. We found that the self-reported volume accounted forapproximately 40 percent of the sales volume. Because of the unique situation applying to Svalbard, theestimate made in this study is believed to be more reliable compared to other studies using sales volume tovalidate self-reports.

    Full Text Available 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.

    The purpose of this project has been to investigate the possibilities to use recycled composites as energy recycling based on microwave pyrolysis and also to evaluate the microwave pyrolysis technique for the recycling of combined materials, such as composites. Composites can be recycled by mechanically grinding into a material which can be used as a filler in virgin composites. However, several earlier studies have showed that this will give a material with inferior quality, and there is presently no economical viable use of the recycled material. Composites can be incinerated together with other waste materials but the high content of inorganic material results in a material with low energy content. Composites typically contain 40-50 weight-% glass fibres, and in some cases be as high as 60-75 weight-%. Consequently, composites often end up at landfill sites and processes to recycle composites do not exit. Large volumes of composites are produced in Europe and these products will largely end up on landfill site after end-of-life as systems to recycle these products do not exist. These composites represent a large amount of energy which presently is not utilized. Processes and materials to produce composites are being developed continuously. This in addition to the need for light weight materials in the aerospace, windmills and automotive industry spurs the use of composites. It is therefore of outmost importance to develop processes to recycle of composites. Recycling of composites by the use of microwave pyrolysis has been studied in this project. Microwave pyrolysis is a process where the material is heated by microwave in an inert environment. The project has been focusing on the recycling of glass fibre reinforced composites as this type of composite makes the large volume of composites. Pyrolysis of glass fibre reinforce composites will result in two fractions - one oil fraction and one inorganic fraction. The oil fraction was analyzed with calorimetry and

    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)

    Three common forest fuels: light thinning material, cull tree and logging residues as well as energy forest fuel (Salix) has been used as fuel pellet materials. Logging residues and Salix were stacked for approximately 6 and 10 months respectively. Parameters varied for each raw material have been the moisture content and the press length of the die. These parameters have been changed to obtain best possible quality, mainly concerning mechanical durability. Pellets were also produced from bark free shavings in order to use as a reference in this study. Physical as well as chemical properties have been compared. It was comparatively easy to press logging residues and Salix into durable pellets and, even with larger press length, the production of pellets was higher than it was for the other raw materials. The density was equal for all pellets while the mechanical durability was better for all tested raw materials compared with the reference material. The fact that all raw materials besides the reference material contains bark which has an improving effect on the degree of hardness. The quality properties were mainly about the same or better for pellets made of light thinning material and cull tree respectively, compared with the reference pellets. However, the ash content was approximately twice as high compared with the reference pellets. The pellets made of logging residues and Salix respectively were of very good quality concerning duration and density but the ash content was approximately 10 times higher than in the reference pellets. Additionally, the nitrogen content was 6-9 times higher compared with the reference pellets.

    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 task of the reactor containment is to protect the environment from radioactive release from the nuclear power plant. The containment is a passive component and one can therefore not verify its success criteria during normal operation. To verify the integrity of the containment one has to perform integrated leakage tests (type A tests). These tests are performed in accordance with either option A or B in the American regulation Appendix J 10 CFR 50. The choice of option is up to the licensee. Option A does not consider the leakage history of the containment. The test interval is fixed and set to three tests equally distributed over ten years. The test pressure shall be at least half of the design basis accident pressure (DBA-pressure). Option B does take the leakage history into consideration and is therefore performance-based. The test interval can be chosen to a maximum of ten years. The test pressure shall be the DBA-pressure. In Sweden the type A tests are performed in accordance with option A. The purpose of this investigation is to investigate whether option B can be used in Sweden without any significant risk impact. Performance of a type A test with half of the design pressure can result in an undetected leak. If a leak is of such characteristic that it does not show any leakage behaviour until it is exposed to a certain level of pressure where it can open itself, the leak can be missed during a test with too low pressure. On the other hand, option B demands a higher test pressure which contributes to the risk during the performance of the type A test. The advantage of a more correct result from the type A test is considered to be greater than the disadvantage of a high test-pressure. Hence, Type A test shall be performed with the realistic DBA-pressure. The work has included a literature study, telephone interviews, local meetings and analyses of existing PSA results and reports in the subject. An investigation of the On-Line Monitoring (OLM) method is

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

    , but also for the network owner, since they cost money and require repair. In the results from Met.no not only an increase in lightning frequency is highlighted, in addition we must also allow for greater variations in different seasons and geographic areas. Areas that until now have been little troubled by lightning may be more exposed, and not least, already known 'problem areas' have more challenges to deal with. Planning under uncertainty. It is difficult with current knowledge to conclude a linear relationship between increased lightning frequency and increase in future outages, but that there will be a connection can not be excluded. Increase in lightning frequency will rise to the need to put this phenomenon in as an important factor in the planning of preventive measures for existing and future construction. Each business must assess the need for specific measures as a basis for prevention and for the dimensioning of the necessary emergency repairs. Through the emergency requirements of the regulations to conduct risk and vulnerability analysis for the individual business, it would be natural from NVE's side to expect that the companies take this or similar studies as the basis for such assessments own challenges. NVE's supervisory activities on emergency area has increased and will increase in the coming year. (Author)

    Syftet med denna kandidatuppsats är se hur ett starkt socialt och affärsmässigt nätverk påverkar valet av bootstrappingmetoder i små och medelstora företag (SME). Detta eftersom SME står för 99,9 procent av samtliga företag på den svenska marknaden och därmed är betydelsefulla för landets ekonomiska tillväxt och sysselsättning. Däremot möter SME svårigheter vid extern finansiering av sin verksamhet. SME kompenserar detta genom att engagera sig i olika ”bootstrappingaktiviteter”. Bootstrapping...

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

  15. Brain uptake of a non-radioactive pseudo-carrier and its effect on the biodistribution of [18 F]AV-133 in mouse brain

    2015-01-01

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

  18. TRE5-A retrotransposition profiling reveals putative RNA polymerase III transcription complex binding sites on the Dictyostelium extrachromosomal rDNA element.

    Directory of Open Access Journals (Sweden)

    Thomas Spaller

    Full Text Available The amoeba Dictyostelium discoideum has a haploid genome in which two thirds of the DNA encodes proteins. Consequently, the space available for selfish mobile elements to expand without excess damage to the host genome is limited. The non-long terminal repeat retrotransposon TRE5-A maintains an active population in the D. discoideum genome and apparently adapted to this gene-dense environment by targeting positions ~47 bp upstream of tRNA genes that are devoid of protein-coding regions. Because only ~24% of tRNA genes are associated with a TRE5-A element in the reference genome, we evaluated whether TRE5-A retrotransposition is limited to this subset of tRNA genes. We determined that a tagged TRE5-A element (TRE5-Absr integrated at 384 of 405 tRNA genes, suggesting that expansion of the current natural TRE5-A population is not limited by the availability of targets. We further observed that TRE5-Absr targets the ribosomal 5S gene on the multicopy extrachromosomal DNA element that carries the ribosomal RNA genes, indicating that TRE5-A integration may extend to the entire RNA polymerase III (Pol III transcriptome. We determined that both natural TRE5-A and cloned TRE5-Absr retrotranspose to locations on the extrachromosomal rDNA element that contain tRNA gene-typical A/B box promoter motifs without displaying any other tRNA gene context. Based on previous data suggesting that TRE5-A targets tRNA genes by locating Pol III transcription complexes, we propose that A/B box loci reflect Pol III transcription complex assembly sites that possess a function in the biology of the extrachromosomal rDNA element.

    The objective of this study was to evaluate the amyloid burden, as assessed by 18 F-florbetapir (AV-45/Amyvid) positron emission tomography PET, in patients with major depressive disorder (MDD) with different subtypes of mild cognitive impairment (MCI) and the relationship between amyloid burden and cognition in MDD patients. The study included 55 MDD patients without dementia and 21 healthy control subjects (HCs) who were assessed using a comprehensive cognitive test battery and 18 F-florbetapir PET imaging. The standardized uptake value ratios (SUVR) in eight cortical regions using the whole cerebellum as reference region were determined and voxel-wise comparisons between the HC and MDD groups were performed. Vascular risk factors, serum homocysteine level and the apolipoprotein E (ApoE) genotype were also determined. Among the 55 MDD patients, 22 (40.0 %) had MCI, 12 (21.8 %) non-amnestic MCI (naMCI) and 10 (18.2 %) amnestic MCI (aMCI). The MDD patients with aMCI had the highest relative 18 F-florbetapir uptake in all cortical regions, and a significant difference in relative 18 F-florbetapir uptake was found in the parietal region as compared with that in naMCI subjects (P < 0.05) and HCs (P < 0.01).

    The objective of this study was to evaluate the amyloid burden, as assessed by {sup 18}F-florbetapir (AV-45/Amyvid) positron emission tomography PET, in patients with major depressive disorder (MDD) with different subtypes of mild cognitive impairment (MCI) and the relationship between amyloid burden and cognition in MDD patients. The study included 55 MDD patients without dementia and 21 healthy control subjects (HCs) who were assessed using a comprehensive cognitive test battery and {sup 18}F-florbetapir PET imaging. The standardized uptake value ratios (SUVR) in eight cortical regions using the whole cerebellum as reference region were determined and voxel-wise comparisons between the HC and MDD groups were performed. Vascular risk factors, serum homocysteine level and the apolipoprotein E (ApoE) genotype were also determined. Among the 55 MDD patients, 22 (40.0 %) had MCI, 12 (21.8 %) non-amnestic MCI (naMCI) and 10 (18.2 %) amnestic MCI (aMCI). The MDD patients with aMCI had the highest relative {sup 18}F-florbetapir uptake in all cortical regions, and a significant difference in relative {sup 18}F-florbetapir uptake was found in the parietal region as compared with that in naMCI subjects (P < 0.05) and HCs (P < 0.01). Voxel-wise analyses revealed significantly increased relative {sup 18}F-florbetapir uptake in the MDD patients with aMCI and naMCI in the frontal, parietal, temporal and occipital areas (P < 0.005). The global cortical SUVR was significantly negatively correlated with MMSE score (r = -0.342, P = 0.010) and memory function (r = -0.328, P = 0.015).

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

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

    Full Text Available «Le fascisme, c’est du théâtre», sostiene Jean Genet, e come tale i suoi legami con la natura e la prassi della messa in scena sono essenziali alla specificità del fenomeno. La resa spettacolare della nazionalizzazione delle masse è stata senz’altro tra i temi fondamentali della ricerca sui totalitarismi. Il mio proposito è qui quello di intarsiare alcuni nuclei consolidati della ricerca storica con le rese squisitamente letterarie di quello che fu poco più che un  decennio di immensi tableaux vivants, visioni di un nuovo ordine di massa. Un’opera d’arte collettiva, basata su una premessa  fondamentale: dare “figurabilità” ai detriti e alle rovine (rimosse? di alcuni miti delle origini propri della cultura romantica, e  consapevolmente avviare e mettere in luce un enorme processo più generale di disgregazione del logos e di tutta la civiltà europea nella sua prospettiva diremo cartesiana, geometrica e razionalista. Il mio discorso si fonda, anche se in breve, su un testo solo: la Gerbe des forces (1937 di A. de Châteaubriant, uno dei più singolari resoconti di pellegrinaggio politico verso il miraggio totalitario che si sia dato tre le due guerre mondiali.

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

  7. A (giant) void is not mandatory to explain away dark energy with a Lemaître-Tolman model

    2010-07-01

    Context. Lemaître-Tolman (L-T) toy models with a central observer have been used to study the effect of large scale inhomogeneities on the SN Ia dimming. Claims that a giant void is mandatory to explain away dark energy in this framework are currently dominating. Aims: Our aim is to show that L-T models exist that reproduce a few features of the ΛCDM model, but do not contain the giant cosmic void. Methods: We propose to use two sets of data - the angular diameter distance together with the redshift-space mass-density and the angular diameter distance together with the expansion rate - both defined on the past null cone as functions of the redshift. We assume that these functions are of the same form as in the ΛCDM model. Using the Mustapha-Hellaby-Ellis algorithm, we numerically transform these initial data into the usual two L-T arbitrary functions and solve the evolution equation to calculate the mass distribution in spacetime. Results: For both models, we find that the current density profile does not exhibit a giant void, but rather a giant hump. However, this hump is not directly observable, since it is in a spacelike relation to a present observer. Conclusions: The alleged existence of the giant void was a consequence of the L-T models used earlier because their generality was limited a priori by needless simplifying assumptions, like, for example, the bang-time function being constant. Instead, one can feed any mass distribution or expansion rate history on the past light cone as initial data to the L-T evolution equation. When a fully general L-T metric is used, the giant void is not implied.

    Considered an institution mainly devoted to astrology and medicine by Simon de Phares and by some historians who believe that he was reliable, the college founded in 1371 by Charles V's first physician, Gervais Chrétien, was in fact primarily dedicated to theological students. It was not before 1377 that there were created there two bursaries for scholares regis, specialising in 'licit mathematical sciences', and two medical fellowships. Yet the influence of the activity of these fellows seems to have been rather moderate and-as far as we can learn from the material still extant, notably from manuscripts that belonged to Maître Gervais' College and to some of its members-this institution was devoted much more to theological studies than to medicine and the quadrivium.

    2015-10-01

    It is common to think of our universe according to the "block universe" concept, which says that spacetime consists of many "stacked" three-surfaces, labelled by some kind of proper time, . Standard ideas do not distinguish past and future, but Ellis' "evolving block universe" tries to make a fundamental distinction. One proposal for this proper time is the proper time measured along the timelike Ricci eigenlines, starting from the big bang. This work investigates the shape of the "Ricci time" surfaces relative to the the null surfaces. We use the Lemaître-Tolman metric as our inhomogeneous spacetime model, and we find the necessary and sufficient conditions for these constant surfaces, , to be spacelike or timelike. Furthermore, we look at the effect of strong gravity domains by determining the location of timelike S regions relative to apparent horizons. We find that constant Ricci time surfaces are always spacelike near the big bang, while at late times (near the crunch or the extreme far future), they are only timelike under special circumstances. At intermediate times, timelike S regions are common unless the variation of the bang time is restricted. The regions where these surfaces become timelike are often adjacent to apparent horizons, but always outside them, and in particular timelike S regions do not occur inside the horizons of black-hole-like models.

    Full Text Available Trout farming poses an increasing threat to quality of the water of clean highland streams. Research of this problem has focused primarily on changes in physico-chemical composition of the water and structure of the river bottom, and less on the effects on living organisms. In the present work, we investigated influence of the farm with the highest trout production in Serbia, the 'Riboteks' Trout Farm on the Trešnjica River, on its macrozoobenthos communities. Our investigations showed that the 'Riboteks' Trout Farm wastewaters caused a clear and statistically significant change of moderate intensity in all measured parameters describing the composition and structure of macrozoobenthos communities. These changes were most pronounced in the part of the watercourse closest to the influx of waste water (locality III but remained statistically significant even 500 m downstream (locality IV and were lost only about 3.5 km away from the influx of the farm's wastewater (locality V. The most pronounced were changes in the participation in total abundance of the Baetidae, Chironomidae, and Plecoptera. Additionally, results of the present work confirmed that the mass of fish on the trout farm is a parameter that adequately defines the strength of its action, above all the intensity of its influence on structure of the macrozoobenthos community.

  18. Lemaître-Tolman-Bondi dust solutions in f (R) gravity

    2017-12-01

    We derive a class of non-static inhomogeneous dust solutions in f(R) gravity described by the Lemaître-Tolman-Bondi (LTB) metric. The field equations are fully integrated for all parameter subcases and compared with analogous subcases of LTB dust solutions of GR. Since the solutions do not admit regular symmetry centres, we have two possibilities: (i) a spherical dust cloud with angle deficit acting as the source of a vacuum Schwarzschild-like solution associated with a global monopole, or (ii) fully regular dust wormholes without angle deficit, whose rest frames are homeomorphic to the Schwarzschild-Kruskal manifold or to a 3d torus. The compatibility between the LTB metric and generic f(R) ansatzes furnishes an ‘inverse procedure’ to generate LTB solutions whose sources are found from the f(R) geometry. While the resulting fluids may have an elusive physical interpretation, they can be used as exact non-perturbative toy models in theoretical and cosmological applications of f(R) theories.

    Introduction: The utility of [{sup 18}F]FPBM [2-(2'-((dimethylamino)methyl)-4'-(3-[{sup 18}F] -fluoropropoxy)phenylthio)benzenamine], a selective serotonin transporter (SERT) tracer, and [{sup 18}F]AV-133 [(+)-2-Hydroxy-3-isobutyl-9-(3-fluoropropoxy)-10-methoxy-1,2,3,4,6, 7-hexahydro-11bH-benzo[a]quinolizine], a selective vesicular monoamine transporter 2 (VMAT2) tracer, were tested in the 6-hydroxydopamine (6-OHDA) unilateral lesioned rat model. Methods: Positron emission tomography (PET) imaging of three 6-OHDA unilateral lesioned male Sprague Dawley rats (Rats 1-3) were performed with [{sup 18}F]FPBM and [{sup 18}F]AV-133 to examine whether changes in SERT and VMAT2 binding, respectively, could be detected in the brain. The brains of the three rats were then removed and examined by in vitro autoradiography with [{sup 18}F]FPBM and the dopamine transporter ligand, [{sup 125}I]IPT [N-(3'-[{sup 125}I]-iodopropen-2'-yl)-2-beta-carbomethoxy-3-beta-(4-chloro phenyl) tropane, for confirmation. Biodistribution of [{sup 18}F]FPBM in a separate group of p-chloroamphetamine (PCA) treated rats were also performed. Results: PET image analysis showed varying levels of SERT binding reduction (Rat 1=-11%, Rat 2=-4%, Rat 3=-43%; n=2) and a clear and definitive loss of VMAT2 binding (Rat 1=-87%, Rat 2=-72%, and Rat 3=-91%; n=1) in the left striatum when compared to the right (non-lesioned side) striatum. The results from PET imaging were corroborated with quantitative in vitro autoradiography. Rats treated with a selective serotonin toxin (p-chloroamphetamine) showed a significant reduction of [{sup 18}F]FPBM uptake in the cortex and hypothalamus regions of the brain. Conclusion: The preliminary data suggest that [{sup 18}F]FPBM and [{sup 18}F]AV-133 may be useful for the examination of serotonergic and dopaminergic neuron integrity, respectively, in the living brain.

    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.

    Full Text Available Nematodes of the genus Elaphostrongylus collected from moose (Alces alces L., reindeer (Rangifer tarandus tarandus L., and red deer (Cervus elaphus L., respectively, were studied by means of scanning electron microscopy. Morphological differences in the ribs of the genital bursa were demonstrated. The Elaphostrongylus species from reindeer and red deer differed from each other in four ribs of the genital bursa. These results agree with the morphological characters of E. cervi and E. rangiferi described by Cameron (1931 and Mitskevitch (1960. The genital bursa of Elaphostrongylus sp. from moose, in accordance with the description of E. alces by Steen et al. (1989 showed characteristics differing from those found in Elaphostrongylus spp. from reindeer and red deer respectively. These results support the hypothesis that there are three separate species of Elaphostrongylus present in Scandinavian Cervidae.

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

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

  13. Cofactor requirement of HpyAV restriction endonuclease.

    Directory of Open Access Journals (Sweden)

    Siu-Hong Chan

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

    2013-01-01

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

    Energy-derived waters containing naphthenic acids (NAs) are complex mixtures often comprising a suite of potentially problematic constituents (e.g. organics, metals, and metalloids) that need treatment prior to beneficial use, including release to receiving aquatic systems. It has previously been suggested that NAs can have biostatic or biocidal properties that could inhibit microbially driven processes (e.g. dissimilatory sulfate reduction) used to transfer or transform metals in passive treatment systems (i.e. constructed wetlands). The overall objective of this study was to measure the effects of a commercially available (Fluka) NA on sulfate-reducing bacteria (SRB), production of sulfides (as acid-volatile sulfides [AVS]), and precipitation of divalent metals (i.e. Cu, Ni, Zn). These endpoints were assessed following 21-d aqueous exposures of NAs using bench-scale reactors. After 21-days, AVS molar concentrations were not statistically different (pAVS production was sufficient in all NA treatments to achieve ∑SEM:AVS AVS) could be used to treat metals occurring in NAs affected waters.

  18. Phenomenological constraints on Lemaître-Tolman-Bondi cosmological inhomogeneities from solar system dynamics

    Science.gov (United States)

    Iorio, Lorenzo

    2010-06-01

    We, first, analytically work out the long-term, i.e. averaged over one orbital revolution, perturbations on the orbit of a test particle moving in a local Fermi frame induced therein by the cosmological tidal effects of the inhomogeneous Lemaître-Tolman-Bondi (LTB) model. The LTB solution has recently attracted attention, among other things, as a possible explanation of the observed cosmic acceleration without resorting to dark energy. Then, we phenomenologically constrain both the parameters K1 doteq ddot frakR / frakR and K2 doteq ddot frakR' / frakR' of the LTB metric in the Fermi frame by using different kinds of solar system data. The corrections Δdot varpi to the standard Newtonian/Einsteinian precessions of the perihelia of the inner planets recently estimated with the EPM ephemerides, compared to our predictions for them, yield preliminarily K1 = (4±8) × 10-26 s-2, K2 = (3±7) × 10-23 s-2. The residuals of the Cassini-based Earth-Saturn range, compared with the numerically integrated LTB range signature, allow to preliminarily obtain K1 approx K2 approx 10-27 s-2. Actually, the LTB effects should be explicitly modeled in the ephemerides softwares, so that the entire planetary and spacecraft data sets should be accordingly re-processed. The LTB-induced distortions of the orbit of a typical object of the Oort cloud with respect to the commonly accepted Newtonian picture, based on the observations of the comet showers from that remote region of the solar system, point towards K1 approx K2lesssim10-30-10-32 s-2. Such figures have to be compared with those inferred from cosmological data which are of the order of K1 approx K2 = -4 × 10-36 s-2.

    2017-01-01

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

    Through the birth and arise of the Internet people has been given great opportunities to make selective selfpresentations online, which in the long run has resulted in an easier retaining of the self- esteem than in the offline world. Simultaneously, the self- esteem has been viewed as a cause for both success and failure since it plays a vital role regarding our attitudes, emotional reactions and behavior. On this basis I wanted to study the relation between self- esteem and self-presentatio...

    Knowledge derived within the RandD programme 'Organic waste as a plant nutrient resource' was in this study used to compare four systems for handling wastewater and organic waste. In the conventional system, the sewage is treated in a sewage plant (SP) with mechanical, biological (incl. 70% nitrogen reduction) and chemical treatment. The sludge is anaerobically digested, dewatered and stored for 20 days. In the energy forest irrigation system the SP has no special nitrogen or phosphorus reduction and the effluent water is stored during winter and used for irrigation during summer. In the liquid compost system the wastewater from the vacuum toilets is co-treated with organic household waste in a reactor at 55 deg C for 7 days. In the other systems, the organic household waste is treated in a central windrow compost. In the urine separation system, the source-separated urine is hygienised by separate storage for 6 months. In the liquid compost and urine separation systems the grey water or the grey water plus faecal wastewater respectively is treated in a SP with phosphorus reduction but without nitrogen reduction. The residual products of the systems fertilise arable land 10 km away. The mass flows, environmental effects, energy turnover and resource utilisation were simulated using ORWARE (ORganic WAste REsearch model), assuming that the wastewater and organic household waste from 20,000 people were treated by the systems. Table values were used for composition of wastewater etc. Industrial wastewater and surface water were excluded from the study. The risk of disease transmission was discussed from the flows and faecal concentrations of the wastewater and from estimated intake of Salmonella, EHEC and Cryptosporidium by some animals under assumed conditions. Throughout the study, it was assumed that the systems function well, without disruptions, and that they are used as intended. The compared environmental effects and resource usage were prioritised in

    Durability of fuel pellets is one of the most important quality variables. The aim of this pilot study was to investigate the effect of moisture content and particle size distribution on the durability of pellets made out of sawdust, logging residues and bark from Norway spruce and Scots pine. Moreover, the durability of pellets made out of logging residues which were exposed to high temperature development was investigated. Pellets were manufactured using a laboratory press CPM Europe. The determined quality parameters were moisture content, percentage of accept-pellets (percentage of pellets of the total amount of raw material), temperature and density of individual pellets. The pelleting process was controlled by monitoring the raw material input to the press, vibration and power consumption. From the results of this study the following preliminary conclusions can be drawn: * Increase moisture content and temperature during pelleting had a positive correlation with the percentage of the accept-pellets, especially concerning the bark assortments, and * Pellets made out of particles smaller than 1 mm resulted in a significantly (Student's t-test) higher percentage of accept-pellets than pellets made out of particles of 1-2 mm. Moreover, the process temperature was probably too low (max. 86 deg C) to activate softening of the lignin. A lower press temperature was sufficient to produce the same percentage of accept-pellets of fresh bark than with other raw materials. A possible reason for that is the presence of high amounts of extractives in bark, which could develop an adhesive nature during thermal treatment.

    The building study is based on the views in the construction sector regarding energy conservation in buildings. The most important problems for discussion with the business were how Enova should cooperate with the sector, what energy carriers there are, how large the potential for energy conservation is and transformation and what measures Enova should use. Energy and energy efficient buildings are not very much focused upon. Through application processes in the existing programs there has development a view that the program has not quite reached the desired target groups. This mainly includes new construction activities and refurbishing. The programs for education and energy management have had a good response and are expected to result in a yearly energy conservation effect of approx. 1.5 TWh in 2010. The project includes information on the new conditions in the sector, investment and operational requirements. Calculations show that buildings may be constructed much more energy efficiently with moderate additional investments. The potential is estimated to approx. 1.4 TWh within 2010 including the potential within refurbishing. The national standards and regulations must give plain requirements to en energy efficiency and consumption in the buildings. In addition the energy marking systems may be good measures in order to promote the construction of energy efficient buildings. There is a need for information and education on energy consumption in all layers of the business. The report suggests the use of supporting measures in order to stimulate the management for energy conservation in buildings. (tk)

    Dengue has emerged in Vietnam 50 years ago and since has become endemo-epidemic throughout the whole country. Each year, major epidemics of dengue fever (DF) and dengue hemorrhagic fever (DHF) hit South Vietnam during the rainy season, causing significant morbidity and mortality, especially among young children. The only preventive measure is vector control, but it is often implemented too late or indiscriminately. The aim of this study was to investigate, in the pre-epidemic stage, the existence of significant changes in vector indices, which will predict DF/DHF outbreaks. We conducted a descriptive transversal study, repeated once a month for four months (March to June) in the village of Locthuan (province Ben Tre) in the Mekong's delta. Adult mosquitoes were caught in 30 houses, and larvae were collected in water holding containers of 50 houses. The houses were randomly selected. Vector densities were calculated according to the indices recommended by WHO. Virological analysis was carried out on lots of female Aedes and larvae in order to determine viral infection rates. Catches of adult mosquitoes collected 496 specimens including 329 Aedes, 139 Culex and 28 Anopheles. Aedes aegypti was present in 63% of visited homes that is an average density of 1.8 mosquitoes per house. The increase in imaginal indices during the 4 months was not significant. The survey of breeding sites of Ae. aegypti identified 1292 water containers in which 71,569 larval specimens were collected. The values of house index, container index [CI] and Breteau index [BI] increased each month, the latter from 166 to 442. This increase was significant for CI and BI. Breeding sites were mostly intra-home, mainly consisting of large and small ceramic jars. Larval density of Ae. aegypti in the containers also increased significantly over the 4 months. It was correlated with the lack of cover and predators such as Mesocyclops spp., Micronecta spp. and larvivorous fishes. Cultivation of 15 pools of

    Reed Canary Grass is a promising crop for biofuel production. For reed canary grass the first year is an establishment year when the small biomass is not harvested. The second year the biomass is usually cut in late autumn but the harvest (removal of the biomass from the field) is delayed until spring. This technique has resulted in lower costs and increases in fuel quality through lower ash contents, including lower contents of chlorine, sodium and potassium. However costs for production are still high, especially establishment costs, fertilization costs and harvesting costs. The aim of this project was to test ways to cut costs per MWh by increased yields, and decreased establishment costs. The methods used have been variety trials to develop more productive plant material, intercropping with nitrogen fixing legumes to reduce the nitrogen demand of the crop, fertilization with waste material (sewage sludge, reed canary grass ash or poultry manure) and harvest at frozen ground as a strategy to reduce soil compaction and harvest damages on the crop. Reed canary grass grown as a fuel has so far been grown as a mono culture. However, when it is been grown for forage, or as a biogas crop, intercropping with legumes has been successful in some studies. In addition to NPK-fertilizers sewage sludge, ash from combustion of reed canary grass and poultry manure was used. An economic calculation showed that the establishment costs (the first two growing seasons) can be lowered by intercropping with red clover. However it is also involves more risks, related to weeds, and cannot be recommended on fallow soil with a large seed bank of weeds. A ten year old reed canary grass ley was used for the experiment. Two 25 m wide strips were harvested with a mower on November 19 2008 when the top soil was frozen. The harvested material was chopped and removed from the field the following day. The following spring, May 19 2009, the remaining reed canary grass on the field was cut with a

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

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

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

    The aim of this study was to examine changes of behaviour and activity patterns in marine soft bottom fauna under the influence of low frequent noise. Controlled experiments were performed at Kristineberg Marine Research Station in Fiskebaeckskil. The experiments were performed utilizing generator and vibrator techniques producing frequencies of 61, 178 and 721 Hz with an average sound pressure around 99 dB re 1 muPa. The selection of frequencies was based upon the sound profile measured at Utgrunden offshore wind farm in Kalmarsund (Ingemansson Technology, 2003) with the aim of recreating natural conditions. In order to quantify the sound exposure, measurements on both sound pressure and water particle acceleration in the test tanks were performed. In total four different marine soft bottom species were studied: a common little white mussel (Abra nitida), brittle star (Amphiura filiformis), brown shrimp (Crangon crangon) and juvenile plaice (Pleuronectes platessa). For the white mussel its burrowing ability was studied. First the speeds of burrowing down into the sediment and thereafter, the burrowing activity in the surface layer of the sediment for the duration of 96 hours were registered. During the experiments with the brittle star Amphiura filiformis the number of arms active in gathering food were observed shortly after the sound had started and for a period of 72 hours. When the brown shrimp was exposed for sound the number of prey items consumed during one day and after 4 days were observed. The study on juvenile plaice was only a shorter pilot study where the fish were exposed for sound during 15 minutes. During this restricted time swimming activity and burrowing activity were observed and after the initial 15 minutes also the respiration frequency during measurement for one minute were documented. The study showed that the burrowing activity increased for the white mussel compared to the controls during exposure of frequencies around 178 Hz after 24

    2010-05-01

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

    The accumulated effects of leaching and aging in a subbase layer of bottom ash were investigated in this study. The paved test road were constructed in 1987 in Linkoeping, Sweden, and has been used until the start of this study. The objective of this study was to investigate: (i) the accumulated effects of leaching and aging (ii) the accumulated effects of load and aging on the geotechnical properties (iii) the prerequisites for separate excavation of the bottom ash for possible reuse. The study started in September 2003 and included tests with falling weight deflectometer, triax testing on undisturbed core samples of bottom ash, sampling for chemical analysis. Three trenches were excavated in the test road, samples of the subbase layer and the subgrade were taken in the shaft walls and brought to the laboratory for leaching tests (EN 12457-2) and extraction, respectively. The extraction procedure was used to estimate extractable and chemically available fractions. It was found that the steady increase of stiffness which had been detected by falling weight deflectometer during the first years after construction had ceased. The undisturbed samples showed stiffness comparable with recently produced bottom ash from the same incineration plant, but lower stiffness if compared with the reference material of crushed rock. The permanent deformation was significantly larger for the samples compared with the crushed rock and recent (1999-2001) bottom ash from other incineration plants. The spatial distribution patterns of leachable easily soluble constituents reveal the existence of horizontal gradients, directed from the center of the road towards the shoulders of the road. This implies that horizontal transport by diffusion is the rate limiting leaching process for all easily soluble constituents underneath the pavement in a road. The bottom ash that was used in the sub-base layer was fresh at the time of the construction of the test road with a pH of about 11. Measured p

    The overall purpose of this paper is to investigate how the premises for the political decision processes in the issue of final disposal of the Swedish nuclear waste are affected by changes in the public opinion climate and global events. The paper therefore focuses on questions concerning how the national political debate leading up to decisions interacts with the media debate, and the public opinion dynamic that arises when the two debates relate to each other. Particular interest is devoted to the arguments and standpoints that occur in politics and media and how they refer to the prevailing public opinion situation and to conditions in the surrounding world of a political, legal, economic, ecological and technological nature. An analysis of the arenas and actors involved in the debates ought to provide valuable knowledge regarding how the political agenda has been formed at different points in time. The following questions are of central interest to the study: - What characterizes the parliamentary and the party political debate in the nuclear waste issue, and in what way have actors, standpoints and arguments changed over time? - What characterizes opinion formation and news reporting in the media in the nuclear waste issue and in what way have actors, standpoints and arguments changed over time? The course of the debate at four different times and in connection with four parliamentary elections during the period 1976-2009 is analyzed in the study. The subject of the analysis includes the four parliamentary parties the Centre Party, the Liberal Party, the Moderates and the Social Democrats. These four parties have been chosen because they have been represented in the Swedish Parliament during the entire period studied and are therefore reasonable to compare. The study has mainly been conducted as a qualitative textual analysis of public print, party documents and media content. The qualitative text analysis is complemented to some extent by other existing

    Aksfusariose er en vanlig sykdom på korn forårsaket av flere ulike Fusarium-arter. En Fusarium-infeksjon på akset gir tap av avling i tillegg til en reduksjon i kvaliteten på kornet. Reduksjonen i kvalitet skjer i hovedsak gjennom produksjon av en rekke toksiske metabolitter (mykotoksiner) som kan være en helserisiko for både dyr og mennesker. I de senere årene har det vært økt fokus på Fusarium og mykotoksiner i korn både i Norge og i store deler av verden. En årsak til det...

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

    Valle de Chalco Solidaridad is located in Mexico City Metropolitan Area in Estado de Mexico, Mexico. In this town there is a sewage canal called “La Compañía”. A wall of this canal collapsed on February 5, 2010 due to heavy rains creating the flooding of four surrounding communities. It is important to point out that this area is frequently exposed to floods. In this work, we consider a critical facility as an essential structure for performance, health care and welfare within a community or/and as a place that can be used as shelter in case of emergency or disaster. Global vulnerability (the sum of the three measured vulnerabilities) of the 25 critical facilities identified in the locations of Avándaro, San Isidro and El Triunfo was assessed using the Community Vulnerability Assessment Tool developed by the National Oceanic and Atmospheric Administration (NOAA). For each critical facility we determined its operational, structural and physical vulnerabilities. For our analysis, we considered the four main natural hazards to which Valle de Chalco is exposed: earthquakes, floods, landslides and sinking. We considered five levels of vulnerability using a scale from 1 to 5, where values range from very low to very high vulnerability, respectively. A critical facilities database was generated by collecting general information for three categories: schools, government and church. Each facility was evaluated considering its location in relation to identified high-risk areas. Our results indicate that in average, the global vulnerability of all facilities is low, however, there are particular cases in which this global vulnerability is high. The average operational vulnerability of the three communities is moderate. The global structural vulnerability (sum of the structural vulnerability for the four analyzed hazards) is moderate. In particular, the structural vulnerability to earthquakes is low, to landslides is very low, to flooding is moderate and to sinking is

  17. Conditional reverse tet-transactivator mouse strains for the efficient induction of TRE-regulated transgenes in mice.

    Directory of Open Access Journals (Sweden)

    Lukas E Dow

    Full Text Available Tetracycline or doxycycline (dox-regulated control of genetic elements allows inducible, reversible and tissue specific regulation of gene expression in mice. This approach provides a means to investigate protein function in specific cell lineages and at defined periods of development and disease. Efficient and stable regulation of cDNAs or non-coding elements (e.g. shRNAs downstream of the tetracycline-regulated element (TRE requires the robust expression of a tet-transactivator protein, commonly the reverse tet-transactivator, rtTA. Most rtTA strains rely on tissue specific promoters that often do not provide sufficient rtTA levels for optimal inducible expression. Here we describe the generation of two mouse strains that enable Cre-dependent, robust expression of rtTA3, providing tissue-restricted and consistent induction of TRE-controlled transgenes. We show that these transgenic strains can be effectively combined with established mouse models of disease, including both Cre/LoxP-based approaches and non Cre-dependent disease models. The integration of these new tools with established mouse models promises the development of more flexible genetic systems to uncover the mechanisms of development and disease pathogenesis.

  18. Transfer Rate Edited experiment for the selective detection of Chemical Exchange via Saturation Transfer (TRE-CEST)

    Chemical Exchange Saturation Transfer (CEST) magnetic resonance experiments have become valuable tools in magnetic resonance for the detection of low concentration solutes with far greater sensitivity than direct detection methods. Accurate measures of rates of chemical exchange provided by CEST are of particular interest to biomedical imaging communities where variations in chemical exchange can be related to subtle variations in biomarker concentration, temperature and pH within tissues using MRI. Despite their name, however, traditional CEST methods are not truly selective for chemical exchange and instead detect all forms of magnetization transfer including through-space NOE. This ambiguity crowds CEST spectra and greatly complicates subsequent data analysis. We have developed a Transfer Rate Edited CEST experiment (TRE-CEST) that uses two different types of solute labeling in order to selectively amplify signals of rapidly exchanging proton species while simultaneously suppressing 'slower' NOE-dominated magnetization transfer processes. This approach is demonstrated in the context of both NMR and MRI, where it is used to detect the labile amide protons of proteins undergoing chemical exchange (at rates ⩾ 30 s-1) while simultaneously eliminating signals originating from slower (∼5 s-1) NOE-mediated magnetization transfer processes. TRE-CEST greatly expands the utility of CEST experiments in complex systems, and in-vivo, in particular, where it is expected to improve the quantification of chemical exchange and magnetization transfer rates while enabling new forms of imaging contrast.

  20. The role of AV and VV optimization for CRT

    Directory of Open Access Journals (Sweden)

    William W. Brabham, M.D.

    2013-06-01

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

    2013-06-01

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

    Full Text Available Teoretisk og praktisk kunnskap fungerer etter ulik logikk, ingen teori kan helt omsettes til praksis. Det er derfor av interesse å undersøke nærmere hvordan nyutdannede lærere opplever både sin fagkunnskap og nyervervede kompetanse i yrket. Undersøkelsen som her blir presentert har følgende problemstilling: Hvordan opplever nyutdannede lærere sin kompetanse i leseopplæring generelt og leseopplæring av elever med lesevansker spesielt? Denne pilotundersøkelsen tar utgangspunkt i Q- metoden; nyutdannede lærere plasserer subjektive utsagn trykt på individuelle kort i en matrise. Pilotundersøkelsen baserer seg på 10 respondenter, vi valgte derfor en kvalitativ analyse av resultatene av Q-sorteringen. Resultatene viser at nyutdannede lærere opplever at de mangler kunnskap og kompetanse både i praktisk leseopplæring generelt og om lesevansker spesielt. Kartleggingsmateriell blir i liten grad brukt som grunnlag for informantenes tilrettelegging av arbeidsmåter i leseopplæring. Inkludering og sammenholdte klasser står sterkt hos informantene, men de savner informasjon om elever med lesevansker og om tilgjengelig hjelpemateriell. Resultatene understreker betydningen av veiledning av nyutdannede lærere og ikke minst deres behov for fora for faglig utvikling, faglig utveksling og refleksive diskusjoner.Nøkkelord: Nyutdannede allmennlærere; opplevd fagkunnskap og kompetanse; leseopplæring, lesevansker, Q-metodologi, læring i praksis.AbstractTheory and practice are based on different logics; this means that no theory can be fully implemented in practice.

  4. Yield Mapping in Salix; Skoerdekartering av salix

    Energy Technology Data Exchange (ETDEWEB)

    Anderson, Christoffer; Gilbertsson, Mikael; Rogstrand, Gustav; Thylen, Lars

    2004-09-01

    The most common species for energy forest production is willow. Willow is able to produce a large amount of biomass in a short period of time. Growing willow has a potential to render a good financial result for the farmer if cultivated on fields with the right conditions and plenty of water. Under the right conditions growing willow can give the farmer a net income of 3,000 SEK (about 430 USD) per hectare and year, which is something that common cereal crops cannot compete with. However, this is not the common case since willow is often grown as a substitute crop on fields where cereal crop yield is low. The aim of this study was to reveal if it is possible to measure yield variability in willow, and if it is possible to describe the reasons for yield variation both within the field but also between different fields. Yield mapping has been used in conventional farming for about a decade. The principles for yield mapping are to continuously measure the yield while registering location by the use of GPS when harvesting the field. The collected data is then used to search for spatial variations within the field, and to try to understand the reasons for this variation. Since there is currently no commercial equipment for yield mapping in willow, a yield mapping system had to be developed within this project. The new system was installed on a Claas Jaguar harvester. The principle for yield mapping on the Claas Jaguar harvester is to measure the distance between the feeding rollers. This distance is correlated to the flow through the harvester. The speed and position of the machine was registered using GPS. Knowing the working width of the harvester this information was used to calculate the yield. All collected data was stored on a PDA computer. Soil samples were also collected from the yield mapped fields. This was to be able to test yield against both physical and chemical soil parameters. The result shows that it is possible to measure spatial variations of yield in

    RNA interference (RNAi) is a powerful technique and is widely used to down-regulate expression of specific genes in cultured cells and in vivo. In this paper, we report our development of a new tetracycline-inducible RNAi expression using a modified TRE-mouse U6 promoter in which the distal sequence element (DSE) was replaced by the tetracycline-responsive element (TRE). The modified TRE-mouse U6 promoter can be activated by a Tet-on version tetracycline-regulated artificial activator rTetOct which was constructed by fusing the rtTA DNA binding domain with the Oct-1 POU activation domain. This rTetOct/TRE-U6 system was successfully applied to conditionally and reversibly down-regulate the expression of endogenous p53 gene in MCF7 cells, and the expression of β-defensin gene (mBin1b) either transiently expressed in COS7 cells or stably expressed in CHO cells

    2010-01-01

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

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

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

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

    2002-12-01

    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.

    To evaluate the occurrence of annoyance from wind turbines, a study was performed in Laholm in May 2000. The aim was to obtain dose response relationships between calculated sound levels and noise annoyance and appropriate sound description as well as analysing the influence of other variables on noise annoyance. A questionnaire survey was performed in 6 areas comprising 16 wind turbines, of which 14 had an effect of 600 kW. The purpose of the study was masked. Among questions on living conditions in the countryside, questions directly related to wind turbines were included. The study population (n=518) comprised one randomly selected subject between the ages of 18 to 75 years in each household living within a calculated wind turbine sound level of 25 to 40 dBA. The response rate was 68.7% (n=356). Calculated distributions of A-weighted sound level were performed for each area and plotted on geographical maps in 2.5 dBA steps. Each dwelling could thus be given a sound level within an interval of 2.5 dBA. The most frequently occurring source of noise annoyance was noise from rotor blades. The proportions of respondents annoyed by noise increased with calculated sound level. Among respondents exposed to sound levels of 35.0-37.5 dBA, 43% responded themselves to be rather or much annoyed. A-weighted sound level was only one variable explaining annoyance. Annoyance was correlated to a larger extent by the intrusiveness of the sound character swishing. Noise annoyance was interrelated to the respondents' opinion of the visual impact of wind turbines, while attitude towards wind power in general had no greater influence. Disturbance of spoilt view was reported to a similar degree as noise disturbance. Further investigations are needed to clarify factors of importance for the disturbance of view. All the wind turbines in the study had constant rotation speed. The greater wind turbines that are now erected often have variable speed, which may lead to a sound

    The structure of the Norwegian offshore sector is characterized by many small technology companies and only a few big ones. At the same time, operators prefer to deal with as few contractors as possible. Thus, the small technology companies must operate as subcontractors or cooperate as joint venture companies in order to win supply contracts. This report studies Kongsberg Offshore AS, or KOS, which is a daughter company of Food Machinery Corporation (FMC). KOS is a leading supplier of ''turnkey'' systems for sub see production and measuring systems and has had great success in its internationalization.

    We present a case of symptomatic ischemic heart failure with an indication for cardiac resynchronization and implantable cardiac defibrillator therapy in primary prevention. After implantation, the patient developed a severe electrical storm with multiple shocks. Hemodynamic improvement based only on AV delay, guided by echocardiography and ECG, brought about a dramatic improvement in the situation. We discuss the pathophysiology of electrical storm occurring immediately after LV pacing.

    The view of networks has changed within the field of policy studies. Once they were considered as hampering the policy process, but today they are accepted as a legitimate policy instrument. The Swedish Government, for instance, makes use of networks to steer society. One attempt to do so is the Sustainable Municipality Programme launched by the Swedish Energy Agency in 2003. Five municipalities where selected to participate in this collaborative process to further sustainable energy policies. This thesis explores the potential of network governance theory as a model for describing policy making. A case study addressing three questions was conducted. Firstly, can the Sustainable Municipality Programme be described within the framework of network governance theory? Secondly, is this governance network successful in its struggle to achieve its goals? Thirdly, can this example of network governance further a discussion exploring a scenario where inter-municipality network governance might pose a challenge to the principle of local government? The first and second question is answered by focusing on four functions that the governance network should fulfil; to give priority to projects; to mobilize resources, to complete projects and, to evaluate the process. In order to answer the first question the case study focuses on the interaction within the governance network. Is the process organised in a fashion recognisable as network governance, as an ideal type of coordination? The analysis shows that network governance theory provides an analytic framework well suited to shed light on the process. The analysis also shows that the three first functions were achieved. Through negotiations the network gave priority to different projects. The thesis focuses on three of these. The first project includes the education of maintenance personnel. The second is a research project, investigating different actors' possibilities to plan for a more sustainable use of energy. The

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

    In 2003, the Danish Parliament in resolution No. B 48 on the dismantling of the nuclear facilities at Risoe gave consent to the government to begin preparation of a decision basis for a Danish final repository for low and intermediate level waste. As a result, a working group under the Ministry of Health and Prevention in 2008 prepared the report 'Decision basis for a Danish final repository for low and medium level radioactive waste'. In this report it was recommended to prepare three parallel preliminary studies: one about the repository concepts with the aim to obtain the necessary decision-making basis for selecting which concepts to analyze within the process of establishing a final repository, one on transportation of radioactive waste to the depot and one about regional mapping with the aim to characterize areas as suitable or unsuitable for locating a repository. The present report contains the main conclusions of each of the three parallel studies in relation to the further localization process. The preliminary studies suggest 22 areas, of which it is recommended to proceed with six in the selection process. The preliminary studies also show that all investigated storage concepts will be possible solutions from a security standpoint. However, there will be greater risks associated with depots near the surface, because they are more subjected to intentional or accidental intrusion. Overall, a medium deep repository will be the most appropriate solution, but it is also a more expensive solution than the near-surface repository. Both subsurface and the deep repositories may be reversible, but it is estimated to increase overall costs and may increase risk related to accidents. The preliminary studies establishes a set of conclusions and recommendations concerning future studies related to repository concepts and safety analyses, including in relation to the specific geology at the selected locations. The transportation studies show that radio

    Within the pulp and paper and saw mill industries there are large quantities of waste heat in the form of moist air or humid flue gases. The temperature and dew point are generally too low for the streams to be useful as process heat. Waste heat can be recovered from humid gas streams e.g. outgoing gas from paper machines, lumber dryers, green liquor flash tanks, flue gases from power and recovery boilers, lime kilns etc. In general, this waste heat is available around 50-65 deg C. One way to utilise the heat on a higher temperature level is by means of heat pumping. The present project studies the possibility to use a recently developed absorption heat pump technology for upgrading waste heat to district heating or process steam. Via direct contact between the absorbent and humid gas stream, the moisture is condensed in the absorbent and the latent heat simultaneously increases the liquid's temperature. A number of process solutions have been calculated in terms of technical and economic performance. The process can be designed for production of hot water or process steam from upgraded waste heat. The end product is indirectly governed be the selection of absorbent or working medium. Investigated absorbents are solutions of potassium formate, sodium hydroxide and phosphoric acid, of which the former two have been included in the techno-economic calculations. The upgraded heat can either save costs by replacing primary fuel or result in increased revenues by exporting produced heat. Internally, the produced heat often replaces oil or electricity on the margin. The choice of regeneration method for the used and diluted absorbent is governed by the mill's energy situation. Industries with large waste heat resources, high value on process steam and use of heat on district heat level, waste heat driven regeneration is advisable. Industries with similar value on MP and LP steam should use back-pressure regeneration with MP steam for optimum cost and energy

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

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

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

    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

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

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

    Wu, N. Eva

    2001-01-01

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

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

    According to the Act on the Financing of Future Expenses for Spent Nuclear Fuel etc. (Financing Act), the Swedish Nuclear Fuel and Waste Management Co. (SKB) must submit, every year, to the Swedish Nuclear Power Inspectorate (SKI), a cost estimate for the management of spent nuclear fuel and for the decommissioning and dismantling of the nuclear power plants. After SKI has examined and evaluated the cost estimates, SKI must submit a proposal to the Government concerning the fee which should be paid by the nuclear power companies per kWh of generated electricity. According to the Financing Act, the reactor owners must pledge collateral in the event that the accumulated fees should be found to be insufficient as a result of early closure of reactors or as a result of underestimating the future expenses of managing the spent nuclear fuel and of decommissioning and dismantling the reactors. The future total expenses resulting from the Financing Act are estimated at about SEK 48 billion at the January 1998 price level. Of this amount, the cost of the final disposal of spent nuclear fuel in SKB's programme is expected to amount to about SEK 12 billion. SKB's estimate comprises the cost of siting, construction and operation of a deep repository for spent nuclear fuel, based on the KBS-3 concept, and a rock cavern for other long-lived waste which SKB plans to locate next to the spent fuel repository. The cost estimate also includes the dismantling and closure of the facility once all of the fuel and the long-lived waste are deposited. The calculations are based on all of the fuel, which will be generated through the operation of the 12 Swedish reactors during a period of 25 years and for every additional year of operation. At the beginning of 1998, SKI commissioned BERGAB to evaluate the cost estimate for the deep disposal of the spent nuclear fuel. The task was divided into two stages, namely a study which was submitted in June 1998 concerning the technical

Se réalise dans le roman une alliance entre l’aspiration à disparaître et le désir de rendre indistinctes fiction et réalité, que nous proposons d’éclairer par la métaphore carrollienne de la traversée du miroir où ces mouvements se conjuguent. Il s’agira de rendre perceptible la dynamique fictionnelle qui anime l’écriture romanesque d’Enrique Vila-Matas. This article endeavours to explore the stakes and modalities of the fictional re-invention of the self that takes place in Docteur Pasavento.In the novel, this reinvention arranges itself in accordance to a complex scheme : by orchestrating his own disappearance in order to confer upon himself new fictitious identities, the eponymous character of the novel becomes a projection of the author himself. In the novel, the aspiration to disappear is thus unified with a desire to blur the boundaries between fiction and reality. I intend to shed light on this union by invoking the Carrollian metaphor of passing “through the looking-glass”. The intention of this article is to render evident the fictional dynamism that underpins the novelistic writings of Enrique Vila-Matas.

  15. Disposal of residue from sifting of combustible waste; Avsaettning av siktrest fraan foerbehandling av braennbart avfall

    Energy Technology Data Exchange (ETDEWEB)

    Niklasson, Fredrik

    2012-11-01

    In waste to energy plants, unwanted species in the fuel may cause corrosion, deposits, agglomeration in the fuel bed, and emissions of pollutants. Countermeasures to such problems are often costly. For at least some of the waste, the fuel properties can be improved by introducing a pretreatment system in which the fine fraction is separated from the waste by sifting. This method has been studied in an earlier Waste Refinery project, WR-06. That study pointed at advantages in performance of the boiler plant and a rough economical analysis indicated substantial benefits. The drawback of the pretreatment was that the residue (the fine fraction) showed as high content of total organic carbon (TOC) as 37 %, by weight. Such a waste fraction is not allowed to be landfilled in Sweden. High TOC content is also a limiting factor for usage as a secondary construction material. To become an applicable pretreatment method, it is necessary to find an appropriate disposal method for the residue material. Present work investigates different possibilities to handle the sifting residue, assuming it has the same properties as in previous study. The residue from sifting needs further treatment, preferably with energy recovery. There are some alternatives, such as combustion, gasification, anaerobic or aerobic digestion. To reduce problems associated by combustion, the waste may be burnt in another more suitable furnace. An alternative is gasification, but that treatment method is not yet an established process for waste fuels. Another option is treatment by anaerobic or aerobic digestion. The high concentrations of metals, however, limit the use of the biologically treated waste to landfilling sites, where it may be utilized as a construction material. The high metal concentrations in the sifting residue imply that it must be kept separate from other biodegradable wastes which are used to produce fertilizers. Thus, this treatment alternative will likely require substantial new

In Sweden, most of the relevant studies have been financed by the Swedish Energy Agency. Therefore, we have analysed all projects within the research programmes funded by the Swedish Energy Agency. This means not only reading scientific papers, but also all kinds of reports, as well as interviews with project leaders. Our result has been examined and discussed at a number of seminars and workshops. Connected to our work we had a reference group with members representing authorities, forestry companies and NGOs. To be able to evaluate the consequences of increased biomass extraction we have related our result to environmental objectives, and goals for forest production, set up by the society (the Swedish parliament). In Sweden we have adopted 16 environmental objectives (http://www.miljomal.nu/Environmental-Objectives-Portal/, in English). Of these especially five objectives are most relevant for our analysis: Reduced climate impact, Natural acidification only, A non-toxic environment, Zero eutrophication and Sustainable forests. The forest production goal is described in the forestry policy (Government proposition 1992/92: 226, in Swedish)

This means not only reading scientific papers, but also all kinds of reports, as well as interviews with project leaders. Our result has been examined and discussed at a number of seminars and workshops. Connected to our work we had a reference group with members representing authorities, forestry companies and NGOs. To be able to evaluate the consequences of increased biomass extraction we have related our result to environmental objectives, and goals for forest production, set up by the society (the Swedish parliament). In Sweden we have adopted 16 environmental objectives (http://www.miljomal.nu/Environmental-Objectives-Portal/, in English). Of these especially five objectives are most relevant for our analysis: Reduced climate impact, Natural acidification only, A non-toxic environment, Zero eutrophication and Sustainable forests. The forest production goal is described in the forestry policy (Government proposition 1992/92: 226, in Swedish)

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

    Full Text Available Utgangspunktet for studien er at naturvitenskaplige fag, særlig anatomi, fysiologi og biokjemi (AFB, oppleves som vanskelig for sykepleierstudentene. Hensikten var å undersøke om læringsverktøyet e-læring, i form av nettester, kan være et effektivt virkemiddel til innlæring av og påvirke læringsutbyttet i AFB.Førsteårsstudentene i bachelorutdanningen i sykepleie ved Høgskolen i Akershus fikk et spørreskjema med 23 spørsmål som ble besvart anonymt.Resultatet av studentundersøkelsen viste at nettoppgavene ble mye brukt, og at studentene mente de ga et godt læringsutbytte. Nettoppgaver med umiddelbar feedback gir stor studentaktivitet og «time-on-task». Testene kan tette hullet mellom det studentene forventes å kunne og det de faktisk kan, og egner seg til faktafag som m å pugges og forstås. E-læring kan gi god hjelp til studenters strukturering av tid, læringsstrategier og selvregulering.Læringsutbyttet av nettester diskuteres i lys av nytten av umiddelbar feedback i et pedagogisk perspektiv.AbstractThe starting point of the study is that the natural sciences, particularly anatomy, physiology and biochemistry (collectively known as APB, are often difficult subjects for nursing students. The aim was to investigate whether e-learning tools, in terms of web services, can be an effective educational tool and affect learning outcomes in APB.First year students in the Bachelor's degree program in nursing at Akershus University College of Applied Sciences received a questionnaire with 23 questions, which were answered anonymously.The results of the student survey showed that online tasks were widely used, and that students felt they resulted in good learning outcomes. Online training with immediate feedback shows great student activity and “time-on-task.” These tests can close the gap between what the students are expected to know and what they actually do, and is suitable for factual subjects requiring both memorization and

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

    Full Text Available O tornar-se avó assinala um período de transição no ciclo de vida familiar, marcado por transformações psíquicas significativas para os avós, caracterizando a quarta individuação. Este trabalho teve como objetivo investigar a experiência de tornar-se avó e sua importância no processo de individuação. Foi utilizado delineamento de estudo de caso coletivo. Onze avós maternas, com idades entre 49 e 66 anos, cujas filhas tiveram seu primeiro filho, responderam a uma entrevista semi-estruturada. Todas as avós tinham tido seus primeiros netos e a entrevista referia-se a sua experiência como avós desses netos. Os dados mostraram que o ser avó é uma fonte de renovação e renascimento. O estudo propiciou que as participantes refletissem sobre seus diferentes papéis familiares: avó, mãe, neta e filha. Os dados sugerem que tornar-se avó possibilita que antigos conflitos sejam repensados, renovando antigos vínculos e desejos, o que permite que a avó dê mais um passo rumo à sua individuação.

    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.

    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.

    Directory of Open Access Journals (Sweden)

    Jahiel Ruffier-Méray

    2017-08-01

    Full Text Available Cette étude porte sur la manière dont le pouvoir politique a tenté d’instrumentaliser le théâtre et examine les différents moyens juridiques utilisés pour transformer l’art théâtral en outil de propagande durant la période révolutionnaire. Durant tout l’Ancien Régime, le système des spectacles privilégiés règne en maître. En plaçant certaines troupes en situation de monopole, l’État fait le choix d’une politique de régulation des salles. Quant à la surveillance des divertissements, elle est assurée à la fois par la police des spectacles et par la censure. En 1789, avec l’abolition des privilèges, les révolutionnaires remettent en cause tout ce système. Inévitablement, ils sont obligés de s’interroger sur les politiques à mener en matière théâtrale et de repenser les modalités de l’offre artistique. Le théâtre apparaît, dès lors, comme un enjeu majeur situé au cœur des préoccupations révolutionnaires. L’art dramatique concentre à lui seul, toutes les questions débattues avec passion à l’Assemblée.

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

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