  3. 17. Non-digestible Polysaccharides and Intestinal Barrier Function : specific focus on its efficacy in elderly and patients with Crohn’s disease

    Författare :John-Peter Ganda Mall; Robert Jan Brummer; Ida Schoultz; Åsa Keita; Mikael Wirén; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-digestible polysachharides; beta-glucan; arabinoxylan; barrier function; permeability; Ussing chamber; elderly; Crohn’s disease;

    Sammanfattning : A large number of elderly suffer from gastrointestinal (GI) symptoms such as constipation and diarrhoea. The underlying mechanisms of age-acquired GI symptoms are not well studied but are necessary to clarify in order to recommend the right treatment. LÄS MER

  4. 18. Design of Thermal Barrier Coating Systems

    Författare :Nicholas Curry; Per Nylén; Nicolaie Markocsan; Robert Vassen; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coating; Atmopsheric Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Thermal barrier coatings (TBC’s) are used to provide both thermal insulation and oxidation protection to high temperature components within gas turbines. The development of turbines for power generation and aviation has led to designs where the operation conditions exceed the upper limits of most conventional engineering materials. LÄS MER

  5. 19. Thermal Barrier Coatings for Diesel Engines

    Författare :Anders Thibblin; Ulf Olofsson; Stefan Jonsson; Senad Dizdar; Uta Klement; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal barrier coatings; diesel engine; thermal cycling fatigue; heat flux; running-in; exhaust manifolds; yttria-stabilized zirconia; gadolinium zirconate; lanthanum zirconate; Machine Design; Maskinkonstruktion;

    Sammanfattning : Reducing the heat losses in heavy-duty diesel engines is of importance for improving engine efficiency and reducing CO2 emissions. Depositing thermal barrier coatings (TBCs) onto engine components has been demonstrated to have great potential to reduce heat loss from the combustion chamber as well as from exhaust components.

  7. 20. Perturbation of the epithelial barrier by enteric pathogens

    Författare :Farideh Tafazoli; Magnusson Karl-Eric; Hakon Leffler; Linköpings universitet; []
    Nyckelord :enteric pathogens: signal transduction; barrier function; MEDICINE; MEDICIN;

    Sammanfattning : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. LÄS MER
