  1. 1. Boundary Layer Parametrization in Numerical Weather Prediction Models

    Författare :Jacob Svensson; Gunilla Svensson; Michael Tjernström; Patrick Samuelsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary-Layer Meteorology; Numerical Weather Prediction; Turbulence parametrization; COAMPS; IFS; meteorologi; Meteorology;

    Sammanfattning : Numerical weather prediction (NWP) and climate models have shown to have a challenge to correctly simulate stable boundary layers and diurnal cycles. This aim of this study is to evaluate, describe and give suggestions for improvements of the descriptions of stable boundary layers in operational NWP models. Two papers are included. LÄS MER

  2. 2. Embryonic Mortality and Sex Ratios in the Tree Sparrow

    Författare :Magnus Svensson; Jan Ekman; Jacob Höglund; Kathryn Arnold; Uppsala universitet; []
    Nyckelord :Ecology; Hatching success; Embryonic mortality; Sex ratio; Density dependence; Parasites; Ekologi; Passer montanus;

    Sammanfattning : Tree sparrows (Passer montanus) have been studied in two areas in Sweden since 1997. At both sites, tree sparrow eggs had remarkably low hatching success. On average only 60% of the eggs hatched. Analyses have shown that this was caused by embryonic mortality, which was highly sex biased. LÄS MER

  3. 3. Laser Speckle Contrast Imaging in Reconstructive Surgery

    Författare :Johan Zötterman; Simon Farnebo; Erik Tesselaar; Jacob Wikner; Henry Svensson; Linköpings universitet; []

    Sammanfattning : ObjectivesReconstructive surgery aims to restore function or normal appearance by reconstructing defective organs after trauma or disease. In patients undergoing reconstructive surgery, previous trauma, surgery or radiotherapy can result in compromised blood supply. LÄS MER
