  1. 1. Lumbar disc herniation surgery

    Författare :Fredrik Strömqvist; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :Lumbar disc herniation surgery; outcome; PROMs; gender differences;

    Sammanfattning : Lumbar disc herniation (LDH) most commonly affects individuals in their early forties but can occur at any age. In most instances,the initial treatment is non-surgical and a clear majority of the patients recover with this management. LÄS MER

  3. 2. Hedge funds and international capital flows

    Författare :Maria Strömqvist; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis consists of four chapters that investigate the performance and capital flows of hedge funds. The first two chapters of the thesis focus on hedge funds that have a pure emerging market strategy. LÄS MER

  4. 3. Nonlinear response in engineered optical materials

    Författare :Gustav Strömqvist; Valdas Pasiskevicius; Peter Smith; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; nonlinear index of refraction; double tungstates; periodic poling; KTiOPO4; quasi-phase matching; parametric down-conversion; mirrorless optical parametric oscillators;

    Sammanfattning : Material and structure engineering are increasingly employed in active optical media,in this context defined as media capable of providing laser or/and optical parametric gain. For laser materials, the main aim of the engineering is to tailor the absorption and emission cross sections in order to optimise the laser performance. LÄS MER

  5. 4. Fluorescence Studies of Membranes -- Proteins and Lipids, their Dynamics and Interactions

    Författare :Johan Strömqvist; Jerker Widengren; Thorsten Wohland; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorescence correlation spectroscopy; cytokinesis; collision theory; protein-protein interactions; lipid dynamics; single-molecule experiment; Biological physics; Biologisk fysik;

    Sammanfattning : In this thesis, fluorescence spectroscopy was utilized to probe protein and lipid dynamics and interactions in their native, or close to native, environments. Thereby insight could be gained into the fundamentals of bacterial cell division and the innateimmune system. A particular focus has been devoted to fluorescence fluctuations. LÄS MER

  7. 5. Homogenization in Perforated Domains

    Författare :Martin Strömqvist; Henrik Shahgholian; Scott Armstrong; KTH; []
    Nyckelord :Mathematics; Matematik;

    Sammanfattning : Homogenization theory is the study of the asymptotic behaviour of solutionsto partial differential equations where high frequency oscillations occur.In the case of a perforated domain the oscillations are due to variations in thedomain of the equation. LÄS MER
