  1. 1. Regulation of human cell viability by the host defence peptide LL-37

    Författare :Daniel Svensson; Kärlfysiologi; []
    Nyckelord :LL-37; cathelicidin; cytotoxicity; host defence peptides; autoimmune diseases; inflammation; vitamin D;

    Sammanfattning : Accumulating evidence suggests that the main human cathelicidin peptide, LL-37, may influence host cell viability and pro-inflammatory signaling when locally overexpressed. LL-37 has pro-inflammatory properties linked to the development of for example psoriasis, rosacea, SLE and atherosclerosis. LÄS MER

  2. 2. Experimental methods to determine model parameters for failure modes of CFRP

    Författare :Daniel Svensson; Ulf Stigh; Svante Alfredsson; Högskolan i Skövde; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; composite; delamination; compressive failure; energy release rate; cohesive modelling; Teknik; Technology;

    Sammanfattning : The focus of this thesis is to develop methods to predict the damage response of Carbon Fibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing cost and weight of CFRP components, it is crucial to enable modelling of the non-linear response associated with various failure modes. LÄS MER

  3. 3. On Cohesive Modelling ofCarbon/Epoxy Composites : Delamination and Fibre Compressive Failure

    Författare :Daniel Svensson; Ulf Stigh; Bent Sørensen; Högskolan i Skövde; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure; Technology; Teknik; Mechanics of Materials; Materialmekanik;

    Sammanfattning : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.

  4. 4. The Bentonite Barrier - Swelling Properties, Redox Chemistry and Mineral Evolution

    Författare :Daniel Svensson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; montmorillonite; bentonite; smectite; freezing; thawing; hydration; intercalation; four-water-layer; ethylene glycol; X-ray diffraction; time-resolved; spatial-resolution; XANES; Fe; redox; iron; ABM; TBT; Äspö;

    Sammanfattning : Bentonite is planned for use as a buffer material in high-level radioactive waste repositories, where safety assessment is performed for very long periods (100-1000 ka). This thesis focuses on the swelling of smectites in liquid water, and analysis of bentonite from field experiments at Äspö Hard Rock Laboratory, Sweden. LÄS MER
