    Sammanfattning : Influenza A virus (IAV) annually infects approximately 5–15 % of the human population, causing ~500,000 deaths globally. Novel IAVs have emerged and spread pandemically in the human population, but have over time established endemic circulation with reduced pathogenicity causing seasonal influenza. The natural reservoir of IAVs is wild waterfowl. LÄS MER

  4. 3. Disintegration of Lime Mud Particles during the Causticizing Operation

    Författare :Pia Tiljander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CaCO3; Ca OH 2; CaO; lime mud; mixing; particles; slaking; causticizing; disintegration; impeller;

    Sammanfattning : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. LÄS MER

  5. 4. Mixing Time and Decarburization Reactions in Side-blown Metallurgical Converters : A Practical Approach using CFD and Thermodynamics

    Författare :Serg Chanouian; Mikael Ersson; Henrik Larsson; Ville-Valtteri Visuri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The side-blowing Argon Oxygen converter (AOD), known for its intense gas stirring and turbulentnature, poses complex fluid dynamics and thermodynamic challenges. Modeling has played asubstantial role in the development of metallurgical converters, particularly in understanding jetbehavior, mixing, flow patterns, and chemical reactions. LÄS MER

  7. 5. Fluid and Solid Particle Dynamics in Stirred Vessels

    Författare :Mattias Ljungqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixing time; pitched blade turbine; impeller modelling; stirred vessels; computational fluid dynamics; multi-fluid model; suspension of solids; phase-Doppler anemometry; laser Doppler anemometry; closed vessels;

    Sammanfattning : The present thesis deals with the fluid dynamics of stirred vessels and particularly those that are to be used in conjunction with solids suspensions. Stirred vessels are very common in the process industry and large amounts of energy can be saved by optimising their operation. LÄS MER
