  1. 11. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons

    Författare :Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Flake graphite; Compacted graphite; Spheroidal graphite; Elastic deformation; Plastic deformation; Modulus of elasticity; Graphite modulus of elasticity; Strength coefficient; Strain hardening exponent; Acoustic emission; Construction materials; Konstruktionsmaterial;

    Sammanfattning : The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. LÄS MER

  3. 13. A Resource-based View on Collaboration between Firms and Local Partners in a Non-urban Swedish Context

    Författare :Lotten Svensson; Celeste Wilderom; Jim Andersén; The Netherlands University of Twente; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; resource-based view; resource based theory; relational RBT; public-private collaboration; action research; intervention; Humaniora-samhällsvetenskap; Humanities and Social sciences;

    Sammanfattning : Is it feasible to stimulate informal collaboration among non-urban firms and local public- and other private-sector actors, whereby they jointly strengthen the competitiveness of these firms? To answer this question, firms’ collaboration with local partner’s actors were examined. Most of the studied firms in this thesis are embedded in a regional “ecosystem” of a country (Sweden), with the usual set of public- and third-sector (not-for-profit) actors. LÄS MER

  4. 14. Aspects of chronic autoimmune thyroiditis in children and adolescents

    Författare :Johan Svensson; Pediatrisk endokrinologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescents; thyroid autoantibodies; enterovirus infection; thyroid ultrasonography; reference standard; goiter; chronic autoimmune thyroiditis; levothyroxine treatment; Medicin människa och djur ; Medicine human and vertebrates ; children;

    Sammanfattning : The aims of this thesis were to 1) compare different methods for detection of antibodies against thyroglobulin (TgAb) and thyroid peroxidase (TPOAb), particulary in children with chronic autoimmune thyroditis (AIT), 2) investigate if maternal enterovirus infection is a risk factor for development of AIT in offspring, 3) ascertain the prevalence of thyroid autoantibodies in cord blood sera from children who later developed AIT, 4) develop a new reference standard for interpretation of normative thyroid volumes in Swedish children, and 5) evaluate the effect of Levothyroxine (L-thyroxine) treatment on thyroid size in children and adolescents with AIT. We found that 1) Methods based on radioimmunoassay (RIA) were more efficient in detecting both TgAb and TPOAb in children with AIT than methods based on agglutination. LÄS MER

  5. 15. Controlling the mobility of organic carbon (OC) ant its impact on metal transport from incineration residues

    Författare :Malin Svensson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Sammanfattning : Incineration residues contain both inorganic and organic material. The organic material may affect the mobility of pollutants in e.g. landfills or geotechnical constructions. LÄS MER
