  1. 41. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners

    Författare :Hans-Olof Backlund; FSCN - Fibre Science and Communication Network; []
    Nyckelord :Shear force; Tangential force; Temperature profile; Thermomechanical pulping;

    Sammanfattning : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. LÄS MER

  2. 42. Fångenskap och flykt : Om frihetstemat i svensk barndomsskildring, reseskildring och science fiction decennierna kring 1970

    Författare :Svante Landgraf; Martin Kylhammar; Emma Eldelin; John Brumo; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Childhood novels; travelogues; science fiction; futures studies; Lars Gustafsson; Jan Myrdal; Sven Lindqvist; Barndomsskildringar; reseskildringar; science fiction; framtidsstudier; Lars Gustafsson; Jan Myrdal; Sven Lindqvist;

    Sammanfattning : Frihet är ett viktigt tema under nittonhundratalet, kanske särskilt decennierna omkring 1970 med allt vad den tiden innehåller av frigörelsekamp, uppror mot gamla traditioner, individualism och kollektivism. Den här avhandlingen spårar det temat genom tre genrer i den svenska litteraturen, från sextiotalet och framåt: den självbiografiska barndomsskildringen, reseskildringen och science fiction-romanen.

  3. 43. Water and Protein Dynamics in Biological Systems Studied by Magnetic Relaxation Dispersion

    Författare :Erik Persson Sunde; Biofysikalisk kemi; []
    Nyckelord :protein dynamics; ubiquitin; BPTI; Escherichia coli; Haloarcula marismortui; nuclear magnetic resonance; protein hydration; magnetic relaxation dispersion; water dynamics; cell water;

    Sammanfattning : The results presented in this thesis demonstrate that the magnetic relaxation dispersion (MRD) technique can provide information of relevance to protein biophysics, magnetic resonance imaging and cell biology. By immobilizing proteins with covalent cross-links, intermittent protein dynamics on the previously inaccessible ns-µs time scale could be probed with MRD via the exchange of water molecules between internal cavities and the surrounding bulk solvent phase.

  4. 44. Kritiskt omdöme i samhällskunskap : Undervisningsutvecklande studier av samhällsanalytiskt resonerande i rättvisefrågor

    Författare :Malin Tväråna; Inger Eriksson; Johan Sandahl; Jan Löfström; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social studies; social science; civics; social science education; fairness; justice; civic reasoning; critical thinking; social science analysis; civic reasoning; teaching and learning; phenomenography; variation theory; intersubjectivity; activity theory; learning study; samhällskunskap; medborgarbildning; samhällskunskapsdidaktik; samhällsanalys; samhällsanalytiskt tänkande; kritiskt tänkande; rättvisa; ämnesdidaktik; didaktik; fenomenografi; variationsteori; intersubjektivitet; verksamhetsteori; learning study; ämnesdidaktik med inriktning mot de samhällsvetenskapliga ämnenas didaktik; Teaching and Learning with Specialisation in the Social Sciences Education;

    Sammanfattning : Teachers struggle to design teaching that that will promote students’ social science knowledge in accordance with the citizenship education purpose of the subject. This study aims to expand the knowledge base of social science education by exploring the meaning of, and teaching for, the ability to critically analyse essentially contested value issues, specifically fairness and justice issues, in social science.

  5. 45. ENDOTHELIAL- EPITHELIAL INTERACTIONS Blood vessels friends or foes?

    Författare :Fredrik Wolfhagen Sand; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood vessels; pancreas; endoderm development; S1P1; N-CAM; diabetic retinopathy; diabetes; tubulogenesis; Cdc42;

    Sammanfattning : Diabetes affects enormous amounts of patients. In type 1 diabetes the insulin producing β cells in the islet of Langerhans are destroyed by the immune system. The β cells, which are located in the pancreas, regulate blood glucose levels. The lack of insulin production requires administration of insulin. LÄS MER
