  4. 23. Daphnids adaptive strategies to UV radiation

    Författare :Carla Eloisa Fernández; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :Cladocera; Zooplankton; Andean lakes; Daphnia; Ultraviolet radiation; Migration strategy; Photo-protection;

    Sammanfattning : This thesis focuses on the adaptive strategies of daphnids that allows them to maintain stable populations while deal with UV radiation, highlighting the differences in the responses that populations with different evolutionary histories may have.Although exposition to lethal doses in nature is unlikely, sub-lethal UV-B radiation doses may have strong impacts on zooplankton.

  5. 24. Theoretical Studies on Artificial Water Splitting-Water Oxidation and Proton Transfer

    Författare :Ying Wang; Hans Ågren; James Gardner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The present thesis is concerned with the theoretical studies on artificial water splitting process. As the quick development of research on utilizing of solar energy, which is a green, clean, and renewable energy source, many research groups focus their attention on artificial photo-synthesis systems inspired by the photosystem I and II.

  7. 25. NMR spectroscopy and MD simulations of carbohydrates

    Författare :Elin Säwén; Göran Widmalm; Manuel Martin Pastor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR specroscopy; MD simulations; carbohydrates; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Knowledge about the structure, conformation and dynamics of carbohydrates is important in our understanding of the way carbohydrates function in biological systems, for example in intermolecular signaling and recognition. This thesis is a summary of five papers studying these properties in carbohydrate-containing molecules with NMR spectroscopy and molecular dynamics simulations. LÄS MER
