  1. 1. Epidemiology of meniscus position: associations with knee symptoms and osteoarthritis

    Författare :Fredrik Svensson; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; meniscus position; Knee osteoarthritis; magnetic resonance imaging; Pain;

    Sammanfattning : Meniscal extrusion (ME) in the knee joint is defined as when the peripheral border of the meniscus is substantially located outside the joint margin. Prior studies have reported that ME is associated with meniscal tears, meniscal degeneration, and the presence of knee osteoarthritis (OA). LÄS MER

  3. 2. Essays on entrepreneurship and bureaucracy

    Författare :Fredrik Svensson; Lars-Erik Wolvén; Roine Johansson; Elisabeth Sundin; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Entrepreneurship; bureaucracy; development; economic growth; agency; structure; Sociology; Sociologi;

    Sammanfattning : The overall aim of this thesis is to explore the theoretical and empirical relationship between entrepreneurship and bureaucracy, and to examine the cause and effect of entrepreneurship. From this overall aim, four specific questions are investigated. LÄS MER

  4. 3. Finite Volume Methods on Quadrilateral and Moving Meshes

    Författare :Fredrik Svensson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; system; kontroll; systems; control; numerical analysis; finite volume method; Datalogi; Computer science; moving mesh method; higher order reconstruction; hyperbolic conservation law;

    Sammanfattning : The topic of this thesis is the study of finite volume methods for hyperbolic conservation laws on non-uniform meshes. A high-order hyperbolic reconstruction method is presented. The method is constructed for quadrilateral meshes, since more realistic hyperbolic problems involve more complicated problem domains than the standard rectangular ones. LÄS MER

  5. 4. Computational Methods in Medicinal Chemistry : Mechanistic Investigations and Virtual Screening Development

    Författare :Fredrik Svensson; Christian Sköld; Anders Karlén; Anna Linusson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DFT; IRAP; Virtual Screening; Catalysis; Palladium; Medicinal Chemistry; Läkemedelskemi;

    Sammanfattning : Computational methods have become an integral part of drug development and can help bring new and better drugs to the market faster. The process of predicting the biological activity of large compound collections is known as virtual screening, and has been instrumental in the development of several drugs today in the market.

  7. 5. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems

    Författare :Fredrik Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle Image Velocimetry PIV ; single-phase; Laser Doppler Anemometry LDA ; mixing; liquid-Liquid; immiscible; stirred tank; Rushton turbine; Computational Fluid Dynamics CFD ; macro-instability; frequency analysis; refraction index matched;

    Sammanfattning : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. LÄS MER
