  1. 1. Collagenous colitis : The influence of inflammation and bile acids on intestinal barrier function

    Författare :Andreas Münch; Magnus Ström; Johan Söderholm; Magnus Simrén; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background and aims: Collagenous colitis (CC) is a diarrheal disorder with an incidence rate of 5-6/100000 inhabitants, affecting mainly middle-aged women. The diagnosis is made by histology of the colonic mucosa. Classical findings are a thickened subepithelial collagenous layer and chronic inflammation in the lamina propria. LÄS MER

  3. 2. Lithium Ion Conductive Membranes Based on Co-continuous Polymer Blends

    Författare :Anette Munch Elmér; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Polymer technology; biopolymers; conductivity measurements; in-situ UV-polymerisation; solution casting; poly methyl methacrylate ; vinylidene fluoride copolymers; poly ethylene carbonate-co-ethylene oxide methacrylate; PEG methacrylate macromonomers; heterogeneous polymer blends; polymer electrolyte membranes; lithium salt containing gels;

    Sammanfattning : There is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. LÄS MER

  4. 3. Nonazeotropic mixtures as working fluids in large heat pumps - Heat transfer in a falling film evaporator and system simulations

    Författare :Karin Munch; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The thesis is divided into two main parts, the first onedealing with heat transfer in the evaporator and the secondone dealing with simulations of the whole heat pump cyclewith nonazeotropic mixtures. One of the aims with the heat transfer studies was to investigate if the additional mass transfer resistance, introduced when mixtures are used, can be reduced in a thin falling film with high turbulence compared with corresponding one for a horizontal tube.

  5. 4. Mitigation of Pressure Pulsations in Axial turbine draft tube with jet injection or solid rod protrusion: A Numerical investigation

    Författare :Henrik Holmström; Cécile Münch-Alligné; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vortex rope mitigation; vortex rope; Strömningslära; Fluid Mechanics;

    Sammanfattning : The introduction of intermittent renewable energy sources, such as wind and solar power, to the power grid, demands some hydraulic turbines to operate at unfavorable operating conditions not initially designed for. Strong swirl develops at loads below the best efficiency point, (BEP) due to angle mismatch between the guide vanes and the fixed runner blades typical for Francis and Propeller turbines. LÄS MER

  7. 5. Mitigation of Pressure Pulsations in Francis Turbine Draft Tube with a GuideVane System : A Numerical Investigation

    Författare :Jesline Joy; Michel Cervantes; Cécile Münch-Alligné; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational fluid dynamics; Francis turbine; Part load; Reduced modelling; Rotating vortex rope; Strömningslära; Fluid Mechanics;

    Sammanfattning : The use of renewable energy such as water and wind to produce electricity has been proven extremely effective in Sweden. The ability of these renewable resources to produce clean output energy counters the adversities caused by non-renewable resources. LÄS MER
