  1. 1. Numerical studies of transtion in wall-bounded flows

    Författare :Ori Levin; Dan Henningson; Nikolaus Adams; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary layer; suction; wall jet; streaks; waves; periodic disturbance; localized disturbance; turbulent spot; algebraic growth; exponential growth; stability; transition thresholds; transition prediction; PSE; DNS; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Disturbances introduced in wall-bounded flows can grow and lead to transition from laminar to turbulent flow. In order to reduce losses or enhance mixing in energy systems, a fundamental understanding of the flow stability and transition mechanism is important. LÄS MER

  3. 2. Toward functional Metal-Organic Frameworks: molecular doping, depth profiling, and surface growth

    Författare :Timofey Liseev; Sascha Ott; Reiner Lomoth; Rob Ameloot; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MOF; water oxidation catalyst; RBS; PSE; depth profiling; SURMOF; Kemi; Chemistry;

    Sammanfattning : In this thesis, selected synthetic aspects of functional Metal-Organic Frameworks (MOFs) are considered. More specifically, the work is focused on MOFs doped with functional molecules in the role of structural linkers. LÄS MER

  4. 3. 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. 4. Eczema in childhood and adolescence

    Författare :Emma Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Eczema (atopic dermatitis) is an itchy inflammatory skin disease that affects many children and adolescents. Eczema associated with IgE antibodies is called atopic eczema (AE), while other eczema is called nonatopic eczema (non-AE). Having a filaggrin (FLG) mutation is associated with increased risk for eczema. LÄS MER

  7. 5. Tryptophan-related Neurotransmission in the Brain: Disturbances Associated with Experimental Hepatic Encephalopathy

    Författare :Peter B F Bergqvist; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tetrodotoxin; serotonin; release; rat; quinolinic acid; potassium; chloroamphetamine; noradrenaline; neurotransmission; microdialysis; hepatic encephalopathy; fenfluramine; drug safety; dopamine; coma; citalopram; ammonia; calcium; brain; tryptophan; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : In the present study, L-tryptophan (TRP)-related disturbances in the brain in experimental hepatic encephalopathy (HE) were investigated. The endogenous NMDA-receptor agonist and L-TRP metabolite quinolinic acid (QUIN) has been suggested to be involved in the pathogenesis of HE. LÄS MER
