  1. 11. Modeling lichen performance in relation to climate : scaling from thalli to landscapes

    Författare :Anna V Jonsson Čabrajić; Kristin Palmqvist; Jon Moen; Per-Anders Esseen; Mikaell Ottosson-Löfvenius; Göran Ågren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lichen; growth; model; micro-climate; hydration; activation; photosynthesis; respiration; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : Lichens can colonize nearly all terrestrial habitats on earth and are functionally important in many ecosystems. Being poikilohydric, their active growth periods are restricted to periods when the thallus is hydrated from atmospheric water sources, such as rain, fog and high relative humidity. LÄS MER

  3. 12. Receptivity of crossflow-dominated boundary layers

    Författare :David Tempelmann; Ardeshir Hanifi; Dan Henningson; Anatoli Tumin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; three-dimensional boundary layers; optimal growth; adjoint solutions; swept wing;

    Sammanfattning : This thesis deals with receptivity mechanisms of three-dimensional, crossflow-dominated boundary layers. The receptivity of two model problems, a swept-flat-plate and a swept-wing boundary layer, is investigated by solving the parabolised stability equations (PSE) as well as by performing direct numerical simulations (DNS).

  4. 13. Stability and Receptivity of Three-Dimensional Boundary Layers

    Författare :David Tempelmann; Dan Henningson; Stefan Hein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional boundary layers; parabolised stability equations; adjoint PSE; crossflow instability; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The stability and the receptivity of three-dimensional flat plate boundary layers is studied employing parabolised stability equations. These allow for computationally efficient parametric studies. Two different sets of equations are used. LÄS MER

  5. 14. Bone health and nutrition treatment. Studies on young women with anorexia nervosa and children with epilepsy

    Författare :Anna Svedlund; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive nutrition treatment; modified Atkins diet; vitamin D; FTO; bone mass; bone biomarkers; growth; skeleton; anorexia nervosa; eating disorder;

    Sammanfattning : Background: Adequate nutritional status is crucial for optimal longitudinal growth and accrual of bone mass during childhood and adolescence. Peak bone mass achieved in young adulthood affects bone health throughout life. LÄS MER

  7. 15. Return to Sender : Essays on Extended producer Responsibility

    Författare :Helén Forslind; Göran Skogh; Astri Muren; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extended Procedur Responsibility; End-of-Life vehicles; Economic incentives; Growth; Producentansvar; Pantsystem; Tillväxt; Economics; Nationalekonomi;

    Sammanfattning : The purpose of this thesis to increase the understanding of how Extended Producer Responsibility (EPR) affects the economy. EPR is a principle stating that producers should be responsible for the environmental impact of their products throughout the life cycle. LÄS MER
