  1. 1. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

    Författare :Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

    Sammanfattning : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. LÄS MER

  3. 2. Towards an understanding of diazocyte development and diazotrophy in the marine cyanobacterium Trichodesmium

    Författare :Gustaf Sandh; Birgitta Bergman; Rehab El-Shehawy; Louis Sherman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Trichodesmium; diazocyte; cell differentiation; nitrogen fixation; cell division; flavodoxin; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Trichodesmium is a filamentous cyanobacterium of great ecological significance as it contributes significantly to primary production in oceans through an efficient nitrogen fixation strategy, including a unique cell type, the diazocyte. The aim of this thesis was to generate a deeper understanding of the structural and molecular background related to the development of diazocytes and the maintenance of diazotrophy in Trichodesmium erythraeum IMS101.

  4. 3. Molecular detection of abundance and activity of marine, symbiotic, N2-fixing cyanobacteria

    Författare :Linnéa Ström; Rachel Foster; Daniel Lundin; Katharina Pawlowski; Rehab El-Shehawy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diatom Diazotroph Association; Richelia; Iron; Phosphorus; Nitrogen; nifH; pstS; exbB; rnpA; växtfysiologi; Plant Physiology; marinbiologi; Marine Biology;

    Sammanfattning : Marine primary productivity in large parts of the oceans is supported by nitrogen fixers (diazotrophs). Richelia, a genus of multiple closely related species of heterocystous filamentous cyanobacterial diazotrophs, are often found in symbioses with a few genera of diatoms. Several Richelia species: R. euintracellularis, R. LÄS MER

  5. 4. Functional genomics of the Baltic Sea cyanobacterium Nodularia spumigena in relation to nitrogen fixation, heterocyst differentiation and toxin production

    Författare :Simina Vintila; Rehab El-Shehawy; Peter Lindblad; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; Nodularia; nitrogen fixation; heterocyst; nitrogenase; ammonium; phosphate; nodularin; Baltic Sea; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Nodularia spumigena is a filamentous, heterocystous cyanobacterium that dominates the annual, toxic cyanobacterial blooms in the Baltic Sea. The blooms are believed to have increased in recent years, due to eutrophication by phosphate and/or nitrogen. Toxicity of these blooms is well-documented and attributed to the hepatotoxin nodularin.

  7. 5. Torken : tvångsvården av alkoholmissbrukare i Sverige 1940-1981

    Författare :Johan Edman; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; alcoholic care institutions; compulsory care; gender; implementation; problem definitions; recommodification; social criticism; social problems; treatment of alcoholics; History subjects; Historieämnen;

    Sammanfattning : This dissertation investigates compulsory care of alcohol abusers in Sweden during the years 1940 to 1981. The purposes of the dissertation are twofold: in part to determine the concrete forms which care services for alcohol abusers took during the years focused on, in part to analyze what connections existed between the development of services and conceptions of the reasons for, consequences of and possible solutions to alcohol abuse.
