  1. 1. Genetic modeling of the Hippo pathway in hematopoietic stem cells

    Författare :Lina Jansson; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stem cells; hematopoiesis; Hippo pathway; hematopoietic stem cells;

    Sammanfattning : Hematopoiesis is the process of blood formation from a limited pool of hematopoietic stem cells (HSCs). These rare stem cells can both self-renew to maintain the HSC pool, and differentiate to continuously replenish lost blood cells. The mechanisms of HSC regulation are not fully known. LÄS MER

  3. 2. Microstructure Investigation of the Oxidation Process in Zircaloy-2 - The Effect of Intermetallic Particle Size

    Författare :Pia Tejland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zircaloy-2; STEM; HAADF; ADF; FIB; SEM; EDX; APT;

    Sammanfattning : Zirconium alloys are widely used in nuclear reactors as fuel cladding tubes because of their low thermal neutron capture cross-section, good corrosion properties and satisfactory mechanical properties. With an improved corrosion resistance the alloys could be used for much longer times in the reactors, increasing fuel burn-up and decreasing the amount of radioactive waste. LÄS MER

  4. 3. Influence of postoperative treatment, surface treatment and stem design on the outcome of primary total hip arthroplasty

    Författare :Truike Thien; Göteborgs universitet; []
    Nyckelord :Primary total hip arthroplasty; anteverted stem; stem design; cemented and cementless fixation; radiostereometry; bone mineral density; clinical outcome;

    Sammanfattning : Aims: The aim of this study was to investigate the influence of postoperative treatment, surface treatment and stem design on the outcome of primary Total Hip Arthroplasty. The main intention was to study anteverted femoral stems. LÄS MER

  5. 4. Family matters : Essays in Applied Microeconomics

    Författare :Sara Mikkelsen; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Portfolio choice; Wealth; Children; Fertility; Consumption; Mobility; Paternity leave; Gender; Education; STEM; Sex composition; Twins; Income;

    Sammanfattning : This thesis consists of four self-contained papers in applied microeconomics with family as a common theme. The first paper documents how the financial portfolios of parents change in response to the birth of a child. LÄS MER

  7. 5. Microstructure of Zirconium Alloys Oxidized in Steam

    Författare :Pia Tejland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDX; ADF; TEM; Zircaloy-2; FIB-SEM; STEM; GD-OES; SPP; SEM; Zirconium; HAADF;

    Sammanfattning : Zirconium alloys are widely used in nuclear reactors as fuel cladding tubes because of their low thermal neutron capture cross-section, good corrosion properties and satisfactory mechanical properties. However, the main limiting factor of these materials is the oxidation behavior. LÄS MER
