  1. 16. Genetic characterization of families with von Willebrand disease

    Författare :Elsa Lanke; Malmö Klinisk koagulationsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mutation; bleeding; coagulation; von Willebrand disease; genetics;

    Sammanfattning : von Willebrand disease (VWD) is the most common hereditary bleeding disorder. It is caused by quantitative and/or qualitative defects of the von Willebrand factor (VWF). The severity of the disease can vary considerably, as can the hereditary patterns. LÄS MER

  3. 17. Development of a methodology for lessons learned practice : From post-project learning to continuous process-based learning

    Författare :Koteshwar Chirumalla; Anja Maier; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktinnovation; Product Innovation;

    Sammanfattning : Product development involves a set of complex problem-solving activities. Their effectiveness depends on how well companies share learnings from one problem-solving experience to another. LÄS MER

  4. 18. Chemistry and Physics of Cu and H2O on ZnO Surfaces : Electron Transfer, Surface Triangles, and Theory

    Författare :Matti Hellström; Kersti Hermansson; Peter Broqvist; Daniel Spångbeg; Jörg Behler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; density functional theory; SCC-DFTB; band-filling correction;

    Sammanfattning : This thesis discusses the chemistry and physics of Cu and H2O on ZnO surfaces, based primarily on results from quantum chemical calculations. The underlying context is heterogeneous catalysis, where Cu/ZnO-mixtures are used in the industrial synthesis of methanol and in the water gas shift reaction.

  5. 19. A study of the rail degradation process to predict rail breaks

    Författare :Saurabh Kumar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Rail infrastructure is a large and costly investment, and has a long life. To realize the benefits from this investment, effective maintenance is required. LÄS MER

  7. 20. Synthesis and Characterization of Transition Metal Diborides

    Författare :Jimmy Thörnberg; Johanna Rosén; Per Persson; Helmut Riedl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DCMS; HiPIMS; Titanium Diboride; Titanium Aluminum Diboride; Chromium Diboride; Microstructure; Hardness; Oxidation Resistance;

    Sammanfattning : This thesis is devoted towards physical vapor deposition (PVD) of thin films of transition-metal (TM) diborides, focused on the material system TiBx, Ti1-xAlxB2-y and CrBx. The metal diborides are a large family of compounds with both metallic and ceramic properties, due to its bonding nature being a mix of covalent and ionic bonds. LÄS MER
