  1. 11. Microscopic colitis : studies of epidemiology, clinical features and nitric oxide

    Författare :Martin Olesen; Robert Löfberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Lymphocytic colitis (LC) and collagenous colitis (CC) arc newly recognised inflammatory bowel diseases belonging to the group of microscopic colitides (MC). They are characterised clinically by chronic non-bloody and watery diarrhoea, and a macroscopically normal or near normal colonic mucosa where diagnostic histopathological abnormalities are found.

  3. 12. Kraft Pulp Fibre Surfaces. Chemical Composition and Effect on Pulp Bleachability

    Författare :Anette Heijnesson Hultén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ray cells; carbohydrates; Kraft pulps; enzymes; lignin; fibre surfaces; metal ions; bleachability;

    Sammanfattning : The work presented in this thesis concerns studies of kraft fibre surfaces in respect of chemical composition and effect on pulp bleachability. Kraft fibre surfaces were studied by mechanical peeling using a disintegrator operated at 20.000-200.000 revolutions and a pulp consistency of 3% or 4. LÄS MER

  4. 13. Enhanced edible films of mixed biopolymers for controlled release

    Författare :Maria Petersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acetem; phase separation; mechanical properties; hylon; edible rilm; release; starch; zein; water vapour premeability;

    Sammanfattning : In recent years there has been a growing interest and increased intensity of research in the area of edible films and coatings. Edible films and coatings can improve quality and shelf-life of food products by acting as barriers to e.g. moisture and oxygen, hence preventing dehydration and oxidative reactions. LÄS MER

  5. 14. Spatial control of biting behavior : to bite and not to slip

    Författare :Joannis Grigoriadis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: During biting and chewing the periodontal mechanoreceptors (PMRs) signal sensory information about the point of attack, the direction of the tooth loads and the intensity of the force with a high sensitivity to very low forces. The sensory information from the PMRs is used by the central nervous system (CNS) to control and position the food morsels and direct the force vectors during biting and chewing. LÄS MER

  7. 15. Numerical computations of wind turbine wakes

    Författare :Stefan S. A. Ivanell; Dan Henningson; Peinke Joachim; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Actuator Line Model; Actuator Disc Model; Wind Turbine Wake; CFD; LES; EllipSys3D; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Numerical simulations of the Navier-Stokes equations are performed to achieve a better understanding of the behaviour of wakes generated by wind turbines. The simulations are performed by combining the in-house developed computer code EllipSys3D with the actuator line and disc methodologies. LÄS MER
