  1. 16. The Influence of Hydrogen on the Radiolytic Oxidation of UO2

    Författare :Niklas Hansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; XPS; Dose-Rate; Radiolytic Oxidation; UO2; MOX; Hydrogen Effect;

    Sammanfattning : Spent nuclear fuel from the nuclear fuel cycle contains radiotoxic nuclides which must be safely stored for over 100 000 years. The Swedish final repository concept, KBS-3, is based on engineered and geological barriers that prevent the nuclear fuel from coming in contact with groundwater, which is the most credible vector to transport the radionuclides into the biosphere.

  3. 17. Phagolysosomal pH measurements in alveolar macrophages

    Författare :Kristina Nyberg Lindborg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :alveolar clearance; alveolar macrophages; phagocytosis; phagolysosomal pH; respiratory burst; silica particles; S. cerevisiae; C. albicans;

    Sammanfattning : Background: Mechanical clearance of insoluble particles from the alveolar part of the lung is known to be a slow process in humans, i. e., one or several years. Particles deposited in the alveolar region are phagocytized by alveolar macrophages (AM). LÄS MER

  4. 18. Biotic and abiotic isotope fractionation of copper and iron : From the lab to the field scale

    Författare :Nathalie Pérez Rodríguez; Dominik Weiss; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : The distribution of the stable isotopes of Cu and Fe in nature is susceptible to isotope fractionation processes during the biogeochemical cycle. Since Cu and Fe are redox sensitive metals, differences in their oxidation states can lead to variations in the stable isotope composition of the aquatic species or compounds that they form. LÄS MER

  5. 19. Experimental studies on thrombosis and thrombolysis : With special reference to importance of lys-plasminogen, active site thrombin inhibitors and stable fish oil

    Författare :Liying Chen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Thrombolysis; thrombosis; recombinant tissue-type plasminogen activator; lys- and glu-plasminogen; aspirin; thrombin inhibitors; platelets; superoxide dismutase; stable fish oil; Kirurgi; Surgery; Kirurgi; rättsmedicin; Forensic Medicine;

    Sammanfattning : Dissolution and prevention of thrombus in the atherosclerotic coronary artery have become an important part of treatment therapy of acute myocardial infarction. However, the currently most effective thrombolytic agent, recombinant tissue-type plasminogen activator (rt-PA), only elicits 80% recanalization of thrombotically occluded coronary arteries and early occlusion occurs in about 40% of successfullyrecanalized vessels.

  7. 20. Function and Adaptation of Acidophiles in Natural and Applied Communities

    Författare :Stephan Christel; Mark Dopson; Michael Schlömann; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acidophiles; Biomining; Psychrophiles; Adaptation; Acid Sulfate Soil; Redox Control; Ecology; Ekologi;

    Sammanfattning : Acidophiles are organisms that have evolved to grow optimally at high concentrations of protons. Members of this group are found in all three domains of life, although most of them belong to the Archaea and Bacteria. LÄS MER
