  3. 2. On starlings and farming: population decline, foraging strategies, cost of reproduction and breeding success

    Författare :Måns Bruun; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; breeding success; foraging strategies; intensification; agricultural methods; population decline; farmland bird; cost of reproduction; Animal ecology; Djurekologi;

    Sammanfattning : The European Starling Sturnus vulgaris as many other farmland bird species has been declining during the last decades. The cause of these declines is generally believed to be changes with in agricultural methods affecting breeding and survival of birds. LÄS MER

  4. 3. Leveraging Intermediate Representations for High-Performance Portable Discrete Fourier Transform Frameworks : with Application to Molecular Dynamics

    Författare :Måns Andersson; Stefano Markidis; Artur Podobas; Niclas Jansson; Ivy Bo Peng; Hartwig Anzt; KTH; []
    Nyckelord :Intermediate Representation; Discrete Fourier Transform; Fast Fourier Transform; Molecular Dynamics; Mellankod; diskret Fouriertransform; snabb Fouriertransform; Molekyldynamik;

    Sammanfattning : The Discrete Fourier Transform (DFT) and its improved formulations, the Fast Fourier Transforms (FFTs), are vital for scientists and engineers in a range of domains from signal processing to the solution of partial differential equations.  A growing trend in Scientific Computing is heterogeneous computing, where accelerators are used instead or together with CPUs.

  5. 4. Solar radiation effects on decomposition and decomposers of plant litter in lakes

    Författare :Måns Denward; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; glucosidase; photo inhibition; photo oxidation; littoral; lakes; ergosterol; fungi; phragmites; bacteria; UV-B; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : This thesis summarizes the results of a series of experiments, from test tube up to field study scale, performed to increase the understanding of solar radiation effects on decomposition and microbial decomposers of plant litter in stagnant water of littoral zones. In conclusion, I suggest that fungi play a significant role in the decomposition of plant litter submersed in lakes, and that their distribution is dependent on detritus quality and water chemistry, but also tends to be inversely related to the occurrence of bacteria attached to the litter.

  7. 5. Aspects on menstrual physiology, pathology and medical treatment of menorrhagia

    Författare :Måns Edlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Menstruation; endometrium; coiled arteries; endothelin; vasoconstriction; progesterone withdrawal; menorrhagia; bleeding disorder; von Willebrand Disease; fibrinolysis; tranexamic acid; desmopressin; platelet dysfunction; thrombin.;

    Sammanfattning : Menstruation is the monthly process by which the endometrium in fertile women is discarded if no pregnancy occurs. The physiology and pathology of menstruation has been extensively studied; still several steps are not fully understood. Menorrhagia, heavy regular menstrual bleeding, is a gynaecological symptom of disease. LÄS MER
