  1. 1. Asymptotic Giant Branch stars viewed up-close and far-off : The physics, chemistry, and evolution of their circumstellar envelopes

    Författare :Matthias Maercker; Hans Olofsson; Fredrik L. Schöier; Laurentius B. F. M. Waters; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AGB stars; evolution; mass-loss; abundances; Astronomy; Astronomi; Astronomy; astronomi;

    Sammanfattning : The asymptotic giant branch (AGB) is the last stage of stellar evolution for stars with masses between 0.8-8 M(sun). This phase is characterised by an intense mass loss, which builds up a circumstellar envelope of dust and gas(CSE). It is through this process that the AGB stars contribute to the chemical evolution of galaxies. LÄS MER

  3. 2. Water in roads: Flow paths and pollutant spread

    Författare :Hedi Rasul; B. Olofsson; Helen Kristine French; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; De-icing salt; Road; Tracer test; ERT; Water content; Road pollutants; Flow pathways; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : For better road construction and maintenance while minimising damage to the environment and groundwater, it is essential to monitor and model hydrological impacts on roads and consider pollution of groundwater. Water content in unbound material in road layers changes continuously and water flow usually occurs along pathways that are the main corridors for pollutant spread to groundwater. LÄS MER

  5. 4. Studies of the vascular endothelial growth factors, VEGFs, and their receptors, focusing on VEGF-B

    Författare :Birgitta Olofsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :vasculogenesis; angiogenesis; VEGF; VEGF-B; VEGF receptors; neuropilin;

    Sammanfattning : The inner lining of all blood- and lymphatic vessels are composed of endothelial cells. Their growth and differentiation are in part regulated by polypeptide growth factors and their receptors. LÄS MER

  7. 5. Immunopathological aspects of equine inflammatory bowel disease

    Författare :Karin Olofsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Intestinal inflammation is a major welfare issue for horses causing colic, diarrhoea and an inability to thrive. One of the diagnoses with poor prognosis is inflammatory bowel disease (eqIBD). LÄS MER
