  1. 1. Capillary and interstitial transport of fluid and solutes across the peritoneal membrane

    Författare :Ola Carlsson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular resistance.; capillary pressure; aquaporins; Capillary permeability; vesicular transport; Urology; nephrology; Urologi; nefrologi;

    Sammanfattning : According to the three-pore model of peritoneal transport the major exchange pathway between the blood and the peritoneal cavity is represented by “small pores”, permeable to small solutes and water. Osmotically induced fluid flow, as during peritoneal dialysis (PD), is postulated to occur to a great extent through a water-only pathway, whereas proteins are predicted to reach the peritoneal cavity by unidirectional convection across “large pores”.

  2. 2. Nanoparticle-based capillary electrochromatography

    Författare :Peter Spégel; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; Analytisk kemi; Analytical chemistry; Nanoparticles; Molecularly imprinted polymers; Capillary electrochromatography;

    Sammanfattning : This thesis concerns a highly efficient nanoparticle-based capillary electrochromatography separation technique and its coupling with mass spectrometric detection. From chromatographic theory, it is well known that the separation efficiency increases with decreasing particle size. LÄS MER

  3. 3. Flow, expansion and processing behaviours of gas-containing filled polyethylene

    Författare :Nabil Khoshaba; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; flow rate; critical pressure; injection moulding; expansion kinetics; fillers; rheological properties; foaming; composite materials; partial pressure; capillary viscometry; Blowing agent;

    Sammanfattning : The utilization of fillers in polymeric materials has exhibited a substantial growth during the last decades. Chalk (calcium carbonate) and glass fibres are two common examples of such fillers. These fillers/reinforcing elements are used in order to reduce the cost of material and change its physical (mechanical) properties. LÄS MER

  4. 4. Nanoparticles in capillary electrophoresis : what are the benefits?

    Författare :David Malmström; Jonas Bergquist; Charlotta Turner; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Kemi;

    Sammanfattning : Capillary electrophoresis is a technique that separate compounds based on charge and size. During the last two decades capillary electrophoresis (CE) and mass spectrometry (MS) has gained in interest, become more robust to use and able to separate neutral analytes. LÄS MER

  5. 5. Diffuse-Interface Simulations of Capillary Phenomena

    Författare :Walter Villanueva; Gustav Amberg; Steffen Hardt; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary-driven flows; wetting; Cahn-Hilliard Navier-Stokes system; multicomponent and multiphase flows; parallel adaptive computing; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Fluid flows mainly driven by capillary forces are presented in this thesis. By means of modeling and simulations, interesting dynamics in capillary-driven flows are revealed such as coalescences, breakups, precursor films, flow instabilities, rapid spreading, rigid body motions, and reactive wetting.
