  1. 1. Experimental and computational studies of turbulent separating internal flows

    Författare :Olle Törnblom; Arne V. Johansson; Michel Stanislas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; turbulence; flow separation; turbulence modelling; asymmetric diffuser; boundary layer; PIV; vortex generator; separation control; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The separating turbulent flow in a plane asymmetric diffuser with 8.5 degrees opening angle is investigated experimentally and computationally. The considered flow case is suitable for fundamental studies of separation, separation control and turbulence modelling. LÄS MER

  3. 2. Formation of Composite Islet Grafts : A novel strategy to promote islet survival and revascularization

    Författare :Ulrika Johansson; Peetra Magnusson; Korsgren Olle; Bo Nilsson; Federico Bertuzzi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet of Langerhans; cytokines and cytokinereceptors expression; endothelial cells; mesenchymal stromal cells; transplantation; revascularization; Clinical immunology; Klinisk immunologi; cellforskning; cellforskning;

    Sammanfattning : The islets of Langerhans are small and delicate spheroid organs scattered in the pancreas responsible for insulin production. Transplantation of isolated islets is a beneficial therapy for patients with a severe form of type 1 diabetes. LÄS MER

  4. 3. Mechanisms and Therapeutic Interventions of Instant Blood-Mediated Inflammatory Reaction (IBMIR)

    Författare :Helena Johansson; Bo Nilsson; Olle Korsgren; Kristina Nilsson-Ekdahl; Tomas Lindahl; Uppsala universitet; []
    Nyckelord :Immunology; Diabetes; Islet transplantation; Islets of Langerhans; Coagulation activation; Complement activation; IBMIR; Tissue factor; Low molecular weight dextran sulfate; Immunologi;

    Sammanfattning : Intraportal transplantation of isolated islets of Langerhans is a procedure approaching clinical acceptance as a treatment for patients with type I diabetes mellitus. One major problem with this treatment is that large amounts of cells are lost at the time of infusion into the portal vein, resulting in a low level of engraftment of the islets. LÄS MER

  5. 4. Metal Hydrogen Interaction and Structural Characterization of Amorphous Materials from first principles

    Författare :Robert Johansson; Ralph Scheicher; Olle Eriksson; Rajeev Ahuja; Peter Mohn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrogen; vanadium; zintl; laves; strain; diffusion; amorphous; dft; molecular dynamics; md; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In this thesis, first-principles calculations based on density functional theory have been employed to investigate metal hydrogen interaction in transition, p-block and rare earth metals. Furthermore, the accuracy of the stochastic quenching method was tested in describing the structure of amorphous Fe(1-x)Zrx. LÄS MER

  7. 5. Samtal om samspel. Kvalitetsuppfattningar i musiklärares dialoger om ensemblespel på gymnasiet

    Författare :Olle Zandén; Bengt Olsson; Airi Rovio Johansson; Petter Dyndahl; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; assessment; criteria; music education; didactics; pedagogy; dialogical theory; upper secondary school; class room ensemble; rock and pop ensemble; teacher professionalisation; Musikvetenskap; Musikundervisning; Ensembler; Gymnasieskolan; Music ¡ Instruction and study; Education; Secondary; High schools;

    Sammanfattning : The purpose of this thesis is to analyse music teachers’ collegiate discourses on ensemble playing with regard to dialogically expressed criteria and conceptions of quality, and to relate these criteria and conceptions to the national governing documents for upper secondary ensemble education. The study has two theoretical perspectives, that is, a didactical perspective and a dialogical perspective. LÄS MER
