  1. 1. In search of a biosensor for DNT detection : Studies of inducer response and specificity of DntR

    Författare :Rosa Lönneborg; Peter Brzezinski; Ray Dixon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DntR; transcriptional regulation; gfp; nitro-aromatic compounds; LysR family; LTTR; TNT; DNT; FACS; directed evolution; random mutagenesis; recombination; structure determination; biokemi; Biochemistry;

    Sammanfattning : The primary aim of the work presented in this thesis was to change the inducer specificity of the DntR protein in order to improve the response to DNT. The long-term goal is to use this protein in a biosensor for DNT, a signature compound for detection of the explosive TNT. LÄS MER

  3. 2. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds

    Författare :Epameinondas Tsiligiannis; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VOC; anthropogenic; biogenic; SOA; atmospheric oxidation; organic aerosols; CIMS; FIGAERO; TMB; isoprene; HOM; organonitrates ONs ; NOx; OH; nitrate NO3 ; Go:PAM; SAPHIR;

    Sammanfattning : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. LÄS MER

  4. 3. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics

    Författare :Lillemor Gustavsson; Magnus Engwall; Anna Schnürer; Ulrika Welander; Mårten Jönsson; Bo Mattiasson; Göran Dave; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic; aerobic; AhR agonists; CALUX; constructed wetlands; Danio rerio; embryotoxicity; genotoxicity; nitroaromatics; sludge; Environmental engineering; Miljöteknik; Enviromental Science; Miljövetenskap;

    Sammanfattning : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. LÄS MER

  5. 4. Formation and Transformation of Atmospheric Brown Carbon (BrC)

    Författare :Kalyan Mitra; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brown carbon BrC ; primary organic aerosol POA ; secondary organic aerosol SOA ; BrC bleaching; BrC browning; Toluene photo-oxidation; NOx; Ammonia; NH3; acidity effects; light absorption;

    Sammanfattning : Atmospheric brown carbon (BrC) aerosol absorbs light in the UV-Vis spectrum and has poorly constrained but potentially large climate forcing impacts. Most current climate models lack detailed chemistry and interlinked properties of atmospheric BrC, that induce large uncertainties in radiative forcing predictions. LÄS MER
