  1. 1. Ligand binding and enzyme catalysis studied by molecular dynamics simulations

    Författare :Tomas Hansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; molecular dynamics simulation; free energy; linear response; drug design; empirical valence bond; HIV protease; protein tyrosine phosphatase; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Molecular dynamics simulations and free energy calculations can be applied to biomolecular systems to predict ligand binding affinities. Combined with hybrid quantum-classical potential energy surfaces, such computations can also be used to probe enzymatic catalysis mechanisms. LÄS MER

  3. 2. Biomarkers in perch (Perca fluviatilis) used in environmental monitoring of the Stockholm recipient and background areas in the Baltic Sea

    Författare :Tomas Hansson; Lennart Balk; Ulf Rannug; Tracy Collier; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomarker; DDT; environmental monitoring; EROD; fish; GSI; nanoinjection; PAH; PCB; Perca fluviatilis; perch; reproduction; Environmental toxicology; Miljötoxikologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : This thesis reports the results of biomarker measurements in three environmental monitoring projects. In the first project, which was part of the Swedish national environmental monitoring, biomarkers were measured annually in female perch (Perca fluviatilis) in two background areas in the Baltic Sea during 1988–2000, resulting in a unique 13-year series of measurements.

  4. 3. Distribution and activity of pelagic fish - acoustic studies in the Baltic Sea

    Författare :Tomas Didrikas; Sture Hansson; Thomas Mehner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pelagic; fish; hydroacoustic; distribution; activity; Baltic; Biology; Biologi;

    Sammanfattning : Fisheries agencies around the Baltic Sea use hydroacoustics to assess stock sizes of herring and sprat. These assessments rely on the assumption that the acoustic properties of Baltic clupeids are the same as North Sea herring. LÄS MER

  5. 4. Berättelser om omsorg : omsorgsetikens kritiska potential i skolans värdeförmedlingsuppdrag

    Författare :Mimmi Norgren Hansson; Niclas Lindström; Tomas Lindgren; Bodil Formark; Arniika Kuusisto; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; values education; moral education; care ethics; peer-relations; compulsory school; Värdeförmedling; värdegrundsuppdraget; omsorgsetik; elevrelationer; mellanstadiet; religionssociologi; sociology of religion; etik; Ethics;

    Sammanfattning : From a care ethics perspective, this thesis aims to discuss and conceptualise children’s experiences of care in Swedish compulsory school. I initiate an ethical discussion focusing on the theoretical core of care ethics and exploring how the framework can be used and developed within the aforementioned educational context. LÄS MER

  7. 5. The influence of biogenic organic compounds on cloud formation

    Författare :Sanna Ekström; Barbara Nozière; Tomas Alsberg; Hans-Christen Hansson; Ernest Weingartner; Stockholms universitet; []
    Nyckelord :biogenic; aerosol; CCN; water-soluble; microorganisms; surfactant; organosulfate; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Aerosols and clouds provide the largest uncertainty in the atmospheric radiation budget. The main focus of this thesis was to investigate the ability of organic compounds in aerosol particles to form clouds, and more specifically those emitted by living organisms. LÄS MER
