  1. 1. Dynamics of the aphid-ant mutualism

    Detta är en avhandling från Stockholm : Department of Zoology, Stockholm University

    Författare :Karolina Tegelaar; Olof Leimar; Judith Bronstein; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mutualism; transgenerational; aphids; aphid-ant; conflict of interest; E -β-farnesene; phenotypic plasticity; predation risk; wing induction; maternal effect; reproductive investment; embryo size; etologi; Ethology;

    Sammanfattning : An appreciation of the role of mutualism is essential when studying ecology and evolution in most ecosystems. Information covering aspects of mutualistic interactions can serve as a complement to the somewhat one-sided perspective from the 1950’s and 60’s that is used when teaching biology. LÄS MER

  2. 2. Modeling of Wind Turbines for Power System Studies

    Detta är en avhandling från Stockholm : Department of Zoology, Stockholm University

    Författare :Tomas Petru; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flicker; fault response; power quality; wind turbine; power system stability; measurements; prediction; verification; grid simulation; modeling;

    Sammanfattning : The power quality impact of wind turbines on the electric grid and the response of the wind turbines to faults in the electric grid are investigated in this thesis. A detailed model of a stall-regulated, fixed-speed wind turbine system capable of predicting the flicker impact on the connected grid is presented and compared with field measurements. LÄS MER

  3. 3. Drosophila immune responses in a model for epithelial hypertrophy

    Detta är en avhandling från Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Författare :Robert Krautz; Ulrich Theopold; Hugo Stocker; [2016]

    Sammanfattning : Apoptosis, differentiation and proliferation have to be tightly balanced and thus regulated to maintain tissue homeostasis. Stress, metabolic cues, genetic variability, infections and physiological host-commensal interactions influence this balance and thus need to be integrated. Therefore, beyond the discrimination between self and non-self (i.e. LÄS MER
