    Sammanfattning : In this thesis I investigate genetic variation in clonal plants within the wind-pollinated plant family Cyperaceae and, in particular, in species of Carex. Clonal diversity and the spatial distribution of clones (genets) within populations was investigated in Carex bigelowii (in Iceland and Scandinavia) and C. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bilkörning; Computer science; Datavetenskap;

    Sammanfattning : Modern vehicles use advanced information systems in vehicles to provide and control a wide variety of functions and features. Even modest vehicles today are equipped with systems that control diverse functions from air-conditioning to high quality audio/video systems. LÄS MER

  5. 4. Immunological Studies using Human and Canine Model Disorders

    Författare :Kerstin M. Ahlgren; Anna Lobell; Olle Kämpe; Kerstin Lindblad-Toh; Roland Jonsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autoimmunity; T cell; T helper cell; B cell; Autoantibodies; Interferon; Interleukin; Dogs; APS-1; Candida albicans; fungus; Immunologi; Immunology; Medicin; Medicine;

    Sammanfattning : The studies presented in this thesis focus on human and canine models for autoimmune disease, with the main aim to gain new knowledge about disease mechanisms and to further evaluate the dog as a model for autoimmune disease. Autoimmune Polyendocrine Syndrome type 1 (APS-1) is a hereditary human multiorgan disease caused by mutations in the autoimmune regulator (AIRE) gene. LÄS MER

  7. 5. Effects of HCO3- and ionic strength on the oxidation and dissolution of UO2

    Författare :Mohammad Moshin Hossain; Mats Jonsson; Olle Wahlberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UO2; H2O2; spent nuclear fuel; HCO3-; ionic strength; oxidation; dissolution; surface site density.; Chemistry; Kemi;

    Sammanfattning : The kinetics for radiation induced dissolution of spent nuclear fuel is a key issue in the safety assessment of a future deep repository. Spent nuclear fuel mainly consists of UO2 and therefore the release of radionuclides (fission products and actinides) is assumed to be governed by the oxidation and subsequent dissolution of the UO2 matrix.
