  2. 1. Atomic Spectroscopy on Fusion Relevant Ions and Studies of Light Impurities in the JET Tokamak

    Author : Magnus Tunklev; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Active and Passive Charge Exchange; Transport; Diffusion; Convection; Neutral Background Densities; Ion temperatures; Fusion; Isoelectronic sequences; Plasma; Atom- och molekylärfysik; Fysicumarkivet A:1999:Tunklev; Ritz formalism; Plume; Atomic and molecular physics;

    Abstract : The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. READ MORE

  4. 2. Electrosurgical plasma-mediated ablation for application in dermal wound and cartilage debridement - Biochemical, microbiological and clinical effects

    Author : Henrik H. Sönnergren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ablation techniques; aerosol; antibacterial; arthroscopy; bacterial spread; bactericidal; bipolar radiofrequency; Candida albicans; cartilage; Coblation; debridement; electrosurgery; Escherichia coli; hydrosurgery; plume; Pseudomonas aeruginosa; Staphyloccus aureus; Streptococcus pyogenes;

    Abstract : The state of matter known as plasma has in the latest decades been investigated within different areas of medical treatment. The work presented in this thesis has focused on a specific type of plasma-based electrosurgical treatment modality (Coblation®) and its biochemical, microbiological and clinical effects on treatment of cartilage and of dermal wounds.

  5. 3. Magmatism in the Cenozoic Ethiopian rift zone : the case against the Afar plume hypothesis

    Author : Begashaw Wolde; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Volcanism and rifting in the Afro-Arabian, i.e. Red Sea - Gulf of Aden - Ethiopian, region have often been attributed to a Tertiary plume centered on Afar, at the junction of the three rifts. READ MORE

  6. 4. Nanoparticles from shipping and road traffic

    Author : Olof Jonathan Westerlund; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Aerosols; Size distributions; Emissions; Plume processes; Shipping; Road traffic;

    Abstract : In the urban environment road traffic is the dominant source of aerosol particles while in coastal and harbour areas shipping is also a significant source. For shipping there are no direct regulations regarding particle emissions. READ MORE

  7. 5. U-Pb baddeleyite geochronology of Precambrian mafic dyke swarms and complexes in southern Africa - regional scale extensional events and the origin of the Bushveld Complex

    Author : Johan Olsson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; U-Pb TIMS geochronology; geochemistry; baddeleyite; mafic dyke swarms; mantle plume; Bushveld Complex; Kaapvaal Craton; Zimbabwe Craton; Archean; Proterozoic;

    Abstract : Dolerite dykes are formed when iron- and magnesium-rich (mafic) mantle-derived magmas ascend through the lithosphere (upper part of the mantle) and crystallize as ‘hydro-fractures’ within the crust. Dykes may exist in great numbers to form dyke swarms (linear or radiating), which can be linked to time periods of continental break-up, or attempted break-up events, associated with voluminous volcanism.
