  1. 16. Exploring phenomena that affect the fate and impact of radioactive materials in the blue mussel

    Författare :Benedict Jaeschke; Clare Bradshaw; Andrew Turner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radioecology; ionising radiation; environmental protection; Mytilus edulis; bioaccumulation; dose-response; ecotoxicology; tritium; particle; hypoxia; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Current protection of the marine environment from radiation is based largely on measuring, estimating and modelling accumulation and impact(s) of radionuclides in a few marine species. Using a relevant marine organism, this thesis focusses on investigating some poorly described phenomena that could cause deviations from predicted measurements. LÄS MER

  3. 17. Genetic, morphological and chemical variation in the genus Harpagophytum

    Författare :Mbaki Muzila; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Harpagophytum procumbens is a valuable medicinal plant but mistakes with plant identification at harvesting, and wilful adulteration using the presumably less efficient H. zeyheri are suggested. A multidisciplinary study with plant material from Botswana was conducted. LÄS MER

  5. 19. Genetic engineering of Yarrowia lipolytica for the sustainable production of food oils

    Författare :Oliver Konzock; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triacyclglycerols; RNA-seq; tolerance; cocoa butter; hydrolysate; yeast; desaturase; filamentation;

    Sammanfattning : The human population and its demand for food oils is constantly growing. However, increasing food oil production currently requires the deforestation of mostly tropical rainforests to allow the plantation of oil crops. LÄS MER

  7. 20. Phosphorylation in State Transition : Less cause more effect

    Författare :Jakob Damkjaer; Jansson Stefan; Eva-Mari Aro; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; Photoacclimation; State Transtion; LHCII Phosphorylation; Lhcb3; Lhcb6; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Study of the Arabidopsis thaliana knockout mutant lacking Lhcb3 (koLhcb3) have revealed a close similarity to the wild type plants. Growth rate, NPQ, qP, Φ(PSII), circular dichroism spectra, pigment composition and content of LCHII trimers have been found to be unaffected by this mutation. LÄS MER
