  1. 1. Optical modelling of conjugated polymers : from materials to devices

    Författare :Nils-Krister Persson; Andy Monkman; Linköpings universitet; []
    Nyckelord :Spectroscopic ellipsomctry; optical modelling; organic solar cell; conjugated polymer; polyfluorene; polythiophene; copolymer; fullerene blend; photovoltaic device; dielectric function; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Measurements and modelling of theoretical properties of polymer-based photovoltaic devices, PPVDs, are the subjects of this thesis. Modelling refers both to modelling of materials, based on extraction of the dielectric function, and to modelling of devices by computer simulation of the optical electrical field inside PPVDs.

  4. 3. Kontinuitetsprincipen i den svenska inkomstbeskattningen

    Författare :Roger Persson Österman; Nils Mattsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LAW JURISPRUDENCE; RÄTTSVETENSKAP JURIDIK;

    Sammanfattning : This dissertation deals with the principle of basis carry-over. The principle of basis carry-over makes possible generation succession and company reorganisations without the accompanying transfers and transactions resulting in taxation for the appreciation of the assets.

  5. 4. Development of Salt-Sensitive Hypertension in Hydronephrosis

    Författare :Mattias Carlström; Erik Persson; Nils Wåhlin; Russell Brown; Göran Bergström; Uppsala universitet; []
    Nyckelord :Physiology; blood pressure; nephrectomy; nitric oxide; oxidative stress; renal function; renin angiotensin system; salt-sensitivity; telemetry; tubuloglomerular feedback; ureteral obstruction; Fysiologi;

    Sammanfattning : Hydronephrosis, due to ureteropelvic junction obstruction, is a common condition in infants with an incidence of approximately 0.5-1%. During the last decade, the surgical management of non-symptomatic hydronephrosis has become more conservative, and the long-term physiological consequences of this new policy are unclear. LÄS MER

  7. 5. Cellular Immune Responses to Allografts and Cytomegalovirus

    Författare :Mats Engstrand; Olle Korsgren; Gunnar Tufveson; Nils Persson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Transplantation; Rejection; Monitoring; Flow Cytometry; MHC; Tetramer; CMV; infection; Immunologi; Immunology; Immunologi;

    Sammanfattning : Today the immunosuppressive treatment is kept to a level were the incidence of acute rejection is below 20% within the first year after transplantation. As a consequence, a group of transplanted patients is over-immunosuppressed and at risk for infections. LÄS MER
