  1. 1. Infammatory response to hyperbaric trauma. An experimental and clinical study

    Författare :Anders Ersson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; intensive care; Anestesiologi; intensivvård; Complement; Cytokines; NGAL; Secretory leukocyte protease inhibitor; decompression sickness; inflammation; Diving; bubbles;

    Sammanfattning : Reductions in ambient pressure liberates gas in various tissues and can result in decompression illness. In this thesis the patophysiological implications of a blood gas interface resulting from decompression was investigated with reference to the influence on biochemical mediators of inflammation.

  3. 2. 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

  4. 3. Simulations of cavitation - from the large vapour structures to the small bubble dynamics

    Författare :Aurélia Vallier; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Very few people around us know the meaning of the word cavitation, except from those who saw the movie "The Hunt for Red October" and can relate cavitation to Sean Connery in a submarine. Some of them know that it corresponds to the formation of bubbles, due to a pressure drop, and causes erosion and noise. However, cavitation is much more complex. LÄS MER

  5. 4. On Supply Chain Incentive Alignment: Insights from a cash supply chain and a trucking service supply chain

    Författare :Johan Lundin; Teknisk logistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supply chain management; Incentive alignment; Cash supply chain; Trucking service supply chain; Mixed methods research;

    Sammanfattning : This dissertation presents a framework for describing, a process for identifying, and a model for evaluating misalignments in the supply chain when varying elements such as structure, processes, and management components. The developed approach makes it possible to address and improve the alignment of supply chain structures, processes, and management components. LÄS MER
