  1. 16. Interaction of flows with slender structures and liquid-infused surfaces

    Författare :Johan Sundin; Shervin Bagheri; Daniel Chung; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow-structure interactions; flow control; turbulent boundary layers; soft sensors; drag reduction; capillary waves; surfactants; Marangoni stress; mixing enhancement; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Surface textures and protrusions can be used to control or gain information about a flow. We investigate the solid-flow interaction of filamentous structures and liquid-infused surfaces (LIS). Both filamentous structures and LIS are used by organisms and can be exploited in technical applications. LÄS MER

  3. 17. On the Fluid Mechanics of Partial Dewatering during Roll Forming in Paper Making

    Författare :Richard Holm; KTH; []
    Nyckelord :Fluid mechanics; roll forming; partial dewatering; capillary waves;

    Sammanfattning : The present work deals with some aspects of the fluidmechanics of paper-making,more specifically partial dewateringduring roll forming. The study is mainly experimental. Pressureand wire position measurements have been carried out in anexperimental facility, the KTH-Former,which models the rollforming zone of a paper machine. LÄS MER

  4. 18. Physiological and morphological aspects of the glomerular barrier in health and disease. Results based on experimental studies in the rat

    Författare :Clara Hjalmarsson; Göteborgs universitet; []
    Nyckelord :glomerular permeability; isolated perfused kidney; charge; endothelial surface layer; glycocalyx; electron microscopy; orosomucoid; nephrotic syndrome; proteinuria;

    Sammanfattning : Tremendous amounts of fluid are filtered every day through the kidneys. The anastomosing capillary loops surrounded by Bowman s capsule, forming the glomerulus, function in accordance with the interplay between the hydrostatic and the colloid osmotic pressure. The result of the action of these mechanisms is the production of primary urine. LÄS MER

  5. 19. Transvascular exchange and organ perfusion with reference to colloid and hypertonic solutions, and to endotoxaemia

    Författare :Staffan Holbeck; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; mannitol; microdialysis; intestine; hypertonic saline; gut; hydroxyethyl starch; gelatin; endotoxin; fluid therapy; dextran; albumin; capillary filtration coefficient; intensivvård; Anestesiologi; urea; Anaesthesiology; intensive care; SIRS; reflection coefficient;

    Sammanfattning : Changes in vascular permeability can immensely change plasma volume and affect the degree of oedema in the body. In diseases with an increased vascular permeability, adequate fluid therapy is of considerable importance to prevent hypovolaemia. LÄS MER

  7. 20. Aspects of sepsis/SIRS - An experimental study on fluid therapy, vitamin C and plasma volume in increased permeability

    Författare :Björn Bark; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : In sepsis, after major surgery or severe trauma, the human body may suffer from various degrees of generalized inflammation, a syndrome called Systemic Inflammatory Response Syndrome (SIRS). One feature of SIRS is increased capillary permeability, caused by disruption of the capillary endothelium due to e.g. LÄS MER
