  1. 16. Photoplethysmography : methodological studies and applications

    Författare :Lars-Göran Lindberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Photoplethysmography (PPG), an optical non-invasive technique for measuring skin perfusion changes, was investigated and evaluated. The method was compared with laser Doppler flowmetry (LDF) when measuring perfusion changes in human fingers and forearms. LÄS MER

  3. 17. Safety and biological aspects of present techniques of haemodialysis

    Författare :Per Jonsson; Hans Dietrich Polaschegg; Umeå universitet; []
    Nyckelord :haemodialysis; safety; leakage current; central dialysis catheter; microbubbles; microemboli; air contamination; transfusion medicine; transfusionsmedicin;

    Sammanfattning : Introduction: Haemodialysis (HD) is a treatment in which blood from the patient is lead through a tubing system into a dialysis device in a extracorporeal circuit. This circuit contains semipermeable membranes (dialyzer). Blood with uraemic toxins flows on one side, and a salt solution flows on the other side. LÄS MER

  4. 18. Impact of cereal food structures on metabolic effects and satiety : the role of processing and product formulation

    Författare :Daniel Johansson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Insulin resistance, high blood glucose and raised total blood cholesterol are major risk factors for cardiovascular disease and type 2 diabetes. Partly they are caused by overweight and obesity. Diet is an important modifiable determinant for these risk factors and understanding how food characteristics, e.g. LÄS MER

  5. 19. Numerical study of particle suspensions in Newtonian and non-Newtonian fluids

    Författare :Dhiya Alghalibi; Luca Brandt; Metin Muradoglu; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inertial suspensions; rheology; non-Newtonian fluids; visco-elastic; sedimentation; deformable particle; hyper-elastic.; tröghetsbehäftad suspension; reologi; icke-Newtonska fluider; vis- koelastik; sedimentering; deformerbara partiklar; hyperelastik; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Solid or deformable particles suspended in a viscous fluid are of scientific and technological interest in a broad range of applications. Pyroclastic flows from volcanoes, sedimentation flows in river bed, food industries, oil-well drilling, as well as blood flow in the human body and the motion of suspended micro-organisms in water (like plankton) are among the possible examples.

  7. 20. Carbohydrate and metabonomic studies by NMR spectroscopy

    Författare :Gustav Nestor; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : NMR spectroscopy can be used to investigate organic and biomolecular structures, both as pure compounds and in complex mixtures. In this thesis NMR spectroscopy was used for carbohydrate and metabonomic studies. LÄS MER
