  1. 1. On some positive effects of swirling flow for the continuous cast mould billets

    Författare :Shavkat Kholmatov; Pär Jönsson; Simon Lille; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; round mould; divergent angle; aspect ratio; temperature distribution; velocity fluctuations; continuous casting of steel; mathematical modeling; CFD; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : Continuous caster moulds are the last and most important stage in the steelmaking process, where inclusions can either be generated or removed. With increasing casting speed using conventional immersion nozzles critical problems, such as unstable bulk mould flow have been noticed. LÄS MER

  3. 2. Laser Doppler perfusion imaging : methodology and skin applications

    Författare :Karin Wårdell; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Over the last decade a number of emerging technologies have become available for the non-invasive study of skin anatomy and physiology. In this thesis, a method for mapping tissue perfusion based on the laser Doppler technique is presented together with some of the associated experimental and clinical applications. LÄS MER

  4. 3. Cellular and Molecular Mechanisms Underlying Congenital Myopathy-related Weakness

    Författare :Johan Lindqvist; Julien Ochala; Anders Arner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; skeletal muscle; skeletal muscle contraction; atrophy; nemaline myopathy; myofibrillar myopathy; myosin; actin;

    Sammanfattning : Congenital myopathies are a rare and heterogeneous group of diseases. They are primarily characterised by skeletal muscle weakness and disease-specific pathological features. They harshly limit ordinary life and in severe cases, these myopathies are associated with early death of the affected individuals. LÄS MER

  5. 4. Large Eddy Simulation of Turbulent Compressible Jets

    Författare :Bernhard Semlitsch; Mihai Mihaescu; Laszlo Fuchs; Paul G. Tucker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressible Flow; Large Eddy Simulation; Acoustic Noise Generation; Near-field Acoustics; Flow Control; Optimization; Modal Flow Decomposition; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Acoustic noise pollution is an environmental aggressor in everyday life. Aero- dynamically generated noise annoys and was linked with health issues. It may be caused by high-speed turbulent free flows (e.g. LÄS MER

  7. 5. Systems microscopy analysis of cell migration

    Författare :Hamdah Shafqat Abbasi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Single cell migration is heterogeneous and a complicated process. It arises from a hugely complex network of multi-scale interactions between molecular and macromolecular entities. LÄS MER
