  1. 1. Wood-Decomposing Fungi: Soil colonization, effects on indigenous bacterial community in soil and hydroxyl radical production

    Författare :Karin Tornberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; hydroxyl radicals; fungal growth; interactions; soil colonization; bacterial community; soil; brown-rot fungi; wood-decomposing fungi; white-rot fungi; Ekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : The extracellular enzyme activities of wood-decomposing basidiomycetes are essential for wood degradation, but are also able to degrade various recalcitrant organic pollutants. The possible application of wood-decomposing fungi in bioremediation has increased the interest in understanding their growth and activity in soil. LÄS MER

  4. 3. DNA-Photosensitization by New Drugs for Photoinactivation of Viruses and Phototherapy of Tumors

    Författare :Claire Kanony; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 7; hydroxyl radicals; singlet oxygen; 8-dihydro-8-oxo-deoxyguanosine; pyropheophorbides; electron transfer; DNA damage; hydrogen abstraction; cyanine dyes;

    Sammanfattning : Cyanines and pyropheophorbides are two classes of photoactivable dyes which are particularly interesting for photosterilization of blood used in transfusion and for treatment of localised cancers by photodynamic therapy (PDT). After a bibliographic review about the principal mechanisms of DNA photosensitization, studies about the photosensitizing properties of these two families of compounds are presented. LÄS MER

  5. 4. Laser Diagnostics and Chemical Modeling of Combustion and Catalytic Processes

    Författare :Michael Försth; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; platinum; OH; elastic light scattering; planar LIF; fuel spray; surface reactions; imaging; Chemkin; hydroxyl; stagnation flow; gas-phase chemistry;

    Sammanfattning : The H2+1/2O2 H2O reaction on hot platinum surfaces has been studied. A stagnation flow geometry was used with a gas mixture of H2 and O2 at subatmospheric pressures. LÄS MER

  7. 5. Physical and Chemical Processes in the Formation of Biogenic secondary Organic Aerosols

    Författare :Åsa M. Jonsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tropospheric chemistry; monoterpenes; ozonolysis; secondary organic aerosol SOA ; G-FROST; AIDA; humidity; temperature; hydroxyl radicals; volatility; pinonaldehyde; climate and health;

    Sammanfattning : Vegetation emits a vast number of biogenic volatile organic compounds (BVOC). In the atmosphere they are oxidised, predominantly by O3, OH radicals or NO3 radicals, depending e.g. on chemical structure. LÄS MER
