  1. 16. 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

  3. 17. Moisture transport and fixation in porous materials at high moisture levels

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building construction; water retention curve; diffusivity; suction; Moisture transport; moisture fixation; absorption; capillary transport; byggnadsteknik;

    Sammanfattning : The work presented in this thesis focuses on developing methods of measuring moisture properties at high moisture levels. Paper I deal with a new method of measuring moisture diffusivity at high moisture levels. Papers II to IV present methods of measuring moisture storage capacity as well as results from such measurements. LÄS MER

  4. 18. Methodological studies of eicosanoid enzyme gene expression in vascular endothelium exposed to biomechanical stress

    Författare :Roya Doroudi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostanoids; endothelium; quantitative RT-PCR; perfusion model; shear stress; intraluminal pressure; immediate-early genes;

    Sammanfattning : Prostaglandins are the major eicosanoids synthesized by vascular endothelial cells, and the vasculature is an important target organ for their bioactive metabolites. In vitro studies have shown that biomechanical forces are important regulators of vascular expression of prostanoid enzymes and release of metabolites. LÄS MER

  5. 19. Muscle Morphology and the Insulin Resistance Syndrome : A Population-Based Study of 70 Year-Old-Men in Uppsala

    Författare :Anu Hedman; Stevo Julius; Uppsala universitet; []
    Nyckelord :Medical sciences; Muscle morphology; fiber distribution; capillary density; insulin resistance syndrome; physical activity; hypertension; insulin-mediated blood flow; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Sammanfattning : Skeletal muscle accounts for the largest part of insulin-mediated glucose uptake. Insulin resistance (IR) is the main component of insulin resistance syndrome (IRS) and is an essential cause of a number of cardiovascular risk factors. LÄS MER

  7. 20. The influence of particle shape of coating pigments on their packing ability and on the flow properties of coating colours

    Författare :Sven Lohmander; KTH; []
    Nyckelord :aspect ratio; capillary viscometry; coating colour; filtration. Particle packing;

    Sammanfattning : The influence of particle shape of coating pigments on theirpacking ability and on the flow properties of coating colourshas been investigated. The particle shapes considered werespherical, flaky and acicular (needle-shaped). LÄS MER
