  2. 1. Plasma-Facing Components in Tokamaks : Studies of Wall Conditioning Processes and Plasma Impact on Diagnostic Mirrors

    Author : Álvaro García Carrasco; Marek Rubel; Marco Cecconello; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasa-wall interactions; wall conditioning; tracers; diagnostic mirrors; ICWC; Physics; Fysik;

    Abstract : Understanding of material migration and its impact on the formation of co-deposited mixed material layers on plasma-facing components is essential for the development of fusion reactors. This thesis focuses on this topic. It is based on experiments performed at JET and TEXTOR tokamaks. READ MORE

  4. 2. Staphylococcal cell wall associated proteins : characteristics and host interactions

    Author : Anna Bjertsjö Rennermalm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Staphylococcus; aureus; epidermidis; cell wall; surface; protein; fibronectinbinding protein; fibrinogen binding protein; internalisation; immunisation; endocarditis; opsonisation;

    Abstract : Staphylococcus aureus and Staphylococcus epidermidis are members of the same family and share several features. S. aureus causes many diseases ranging from mild skin infections to deep tissue infections and septic shock. S. READ MORE

  5. 3. In vivo Pharmacokinetic Interactions of Finasteride and Identification of Novel Metabolites

    Author : Anna Lundahl; Hans Lennernäs; Dennis A Smith; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; drug-drug interactions; herb-drug interactions; pharmacokinetics; metabolism; CYP3A4; hydroxylation; glucuronidation; UGT enzymes; mass spectrometry; biliary excretion; urinary excretion; finasteride; PHARMACY; FARMACI;

    Abstract : The general aim of this thesis was to improve the understanding of the in vivo pharmacokinetics and, in particular, the metabolism of finasteride, a 5α-reductase inhibitor used in the treatment of enlarged prostate glands and male pattern baldness. CYP3A4 has been identified as the major enzyme involved in the sequential metabolism of finasteride to ω-OH finasteride (M1) and ω-COOH finasteride (M3). READ MORE

  6. 4. Non-linear dynamics of Alfvén eigenmodes excited by fast ions in tokamaks

    Author : Tommy Bergkvist; Torbjörn Hellsten; Fulvio Zonca; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fusion plasma; tokamak; MHD; toroidal Alfvén eigenmodes; thermonuclear alpha particles; ion cyclotron resonance heating; Electrophysics; Elektrofysik;

    Abstract : The tokamak is so far the most promising magnetic configuration for achieving a net production of fusion energy. The D-T fusion reactions result in 3.5 MeV alpha-particles, which may destabilize Alfvén eigenmodes through wave-particle interaction. READ MORE

  7. 5. Studies of plasma-facing materials and macromolecules using scanning probe microscopy

    Author : Nils Almqvist; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Abstract : The main topic of this thesis is experimental analysis of material surfaces using scanning probe microscopies. These microscopes are used for characterization through high-resolution topographical imaging, but also for controlled modification of surfaces and molecules. READ MORE
