The study is longitudinal in character and consists of qualitative interviews conducted with eighteen students belonging to the same nursing class. The students were interviewed on four occasions during

The aim of the Swedish educational policy is educational participation and academic achieivement for all children, irrespective of ethnic background. Majority language instruction is an important tool used to achieve this goal. We argue that taking lessons in Swedish-as-a-second-language (S2) sets children apart in their class and limits their possibilities to interact with Swedish children and th

Popular Abstract in Swedish Avhandlingen analyserar Guatemalas råvaruexport under perioden 1524-1945.In the integrated institutional-staples-‘vent for surplus’ approach, the opening of trade occurs because of initial demand. Once demand is determined, competitiveness is a function of transportation costs, entrepreneurship, capital, land and labour costs, as well as the role played by the State. When all these factors promote competitiveness within an institutional framework that decreased transac

Regression testing is expensive and may consume much of organizations’ software development budgets. Thus, it is of interest to reduce the total time devoted to test execution by using test selection techniques. Many techniques have been proposed but few have been evaluated on real-world, large scale systems. In this paper we report on an empirical evaluation of using the class firewall regression

Popular Abstract in Swedish Sexuella övergrepp väcker starka känslor hos oss. Ibland tycks känslorna bli så svåra att vi försöker utestänga den plågsamma verkligheten genom att "blunda" för faktum. För att studera hur människor handskas med förekomsten av ett sexuellt övergrepp på ett barn i en bild, framställdes en bild, som avsåg att visa ett sådant övergrepp. Bilden visades för ett stort antal

In recent decades, the development of technology that aids in documenting, analysing and communicating information regarding archaeological sites has affected the way that historical information is transmitted and perceived by the community. Digital technologies have affected archaeology at all levels; for example, novel investigation methods have highlighted new and unknown aspects of archaeologi

Popular Abstract in Swedish Tensider är amfifila molekyler, vilket innebär att de består av två delar. En av dessa är hydrofil (”vattenälskande”) och den andra är hydrofob (”vattenhatande”). Detta faktum ger tensider speciella egenskaper av vilken den viktigaste är att de självaggregerar i lösningsmedel (främst vatten), och bildar olika typer av aggregat, varav micellen är den mest kända. Dess spePhase diagrams of mixed alkylglucoside surfactants, n-nonyl-b-D-glucopyranoside and n-decyl-b-D-glucopyranoside (C9G1 and C10G1) have been examined for the purpose of determining the microstructure surrounding a closed-loop miscibiliyt gap. There are large deuterium isotope effects on the phase diagram. NMR-self diffusion, cryoTEM and TRFQ experiments show the presence of long interconnect network

Popular Abstract in Swedish Industriell produktion av bärkonserver innefattar flera enhetsoperationer, vilka alla påverkar sensoriska så väl som näringsmässiga kvaliteter hos produkten. Upptiningen är ett speciellt kritiskt steg eftersom förändringar i både kemisk sammansättning och textur sker. Upptining av jordgubbar i designade lösningar visade att bärens fasthet såväl som viktsförlusterna gickThe industrial production of preserves includes several unit operations which all affects sensorial properties as well as the nutritional value of the final product. Thawing is a crucial unit operation, since then both chemical and physical changes take place. Thawing strawberries in selected aqueous media could gave both firmer strawberries and smaller weight loss than if air was used as the tha

Abstract The objective of this investigation was to characterise the immunomodulatory or immunosuppressive effects of single drug treatment and the potential synergistic or additive effects of combined treatment with the focus on ciprofloxacin, thalidomide, mycophenolate mofetil, azathioprine, cyclophosphamide or leflunomide added to cyclosporin A (CyA). A rat cardiac transplant model was used to

Popular Abstract in Swedish Den pågående ökningen av växthusgaser i atmosfären orsakar en ökning av den globala medeltemperaturen. En viktig påverkande faktor för koncentrationen koldioxid (CO2) i atmosfären är utbytet mellan atmosfären och biosfären; fotosyntesen tar upp CO2 och respirationen släpper ut CO2, vilket resulterar i ett nettoutbyte. För att öka vår förståelse av den spatiala och tempoThe ongoing increase in atmospheric greenhouse gas concentrations causes an increase in the global mean air temperature. One important moderator of the atmospheric carbon dioxide (CO2) concentration is the gas exchange between the atmosphere and the biosphere; photosynthesis extracts and respiration releases CO2, resulting in a net exchange. A variety of methods are used to improve our understandi

The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. Photosynthetic oxygenation overcomes these limita

Syftet med denna undersökning var att bestämma en 1 kg isvästs kylverkan på kroppen vid brandmansarbete. Testerna genomfördes i en klimatkammare, i en container med extrem strålningsvärme och i ett rökdykningshus med värme och tungt arbete. Den faktiska kylverkan mättes också med en termisk docka.

The experiments were carried out in a climatic chamber, in a container under extreme radiant heat, and during simulated smoke-diving. In addition, the physical cooling effect of the ice-vest was measured with a thermal mannequin.

BACKGROUND AND AIMS: The aims of this study were to investigate (1) if P2Y(12) polymorphisms defining the P2Y(12) H2 allele are associated with any other SNPs that may explain the previously reported association with increased ADP induced platelet activation and association with peripheral arterial disease and coronary artery disease and (2) if such variants are associated with acute myocardial in

BACKGROUND: Hormone-sensitive lipase (HSL) is a key enzyme in the mobilization of fatty acids from stored triacylglycerols. Its activity is regulated by reversible protein phosphorylation. In rat HSL Ser563, Ser659 and Ser660 have been shown to be phosphorylated by protein kinase A (PKA) in vitro as well as in vivo. METHODOLOGY/PRINCIPAL FINDINGS: In this study we employed site-directed mutagenesi

Fatty acids (FA) have crucial functions in animals, affecting e.g. inflammatory responses, thermoregulation, and cell membrane fluidity. Diet and ambient temperature affect animals’ FA composition, which, in turn, may influence these physiological processes. Great tit (Parus major) −common in both urban and rural habitats− are mainly granivorous during winter and insectivorous during summer. These

This article presents a study of three asylum-seeking men from Iran and Afghanistan. It aimed to explore how and if they experienced occupations as occupations in a Danish asylum centre and how their life experience shaped their choice and value of current occupations. In-depth narrative interviews explored the participants’ occupational history and its influence on their occupations in the asylum

Tannerella forsythia is a poorly studied pathogen despite being one of the main causes of periodontitis, which is an inflammatory disease of the supporting structures of the teeth. We found that despite being recognized by all complement pathways, T. forsythia is resistant to killing by human complement, which is present at up to 70% of serum concentration in gingival crevicular fluid.
