  1. 41. Multi-scale fabric evolution during hydro-mechanical probing of fine-grained soils

    Författare :Georgios Birmpilis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray Computed Tomography; clay fabric; geomechanical testing; sensitive clays; X-ray Scattering;

    Sammanfattning : The majority of the studies on sensitive clays so far have focused on the hydro-mechanical response at engineering scale, using concepts from continuum mechanics. The fundamental mechanisms at particle scale, underpinning the emerging response, have so far been studied with post mortem analyses. LÄS MER

  3. 42. Clinical and genetical aspects of Celiac Disease

    Författare :Audur Gudjonsdottir; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; celiac disease; sib-pair; screening; genome-wide scan; linkage analysis; heritability; genotypes; DQ2-negative; phenotypes; autoimmune disease;

    Sammanfattning : Celiac disease (CD), or gluten-sensitive enteropathy, is one of the most common chronic diseases in childhood but is diagnosed in all ages. CD is a genetically driven immunological intolerance to dietary gluten. Th e treatment is a gluten-free diet. LÄS MER

  4. 43. Experimental Study on Cold Lap Formation in Tandem Gas Metal Arc Welding

    Författare :Peigang Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxides; imperfection; spatter; silicon; lack of fusion; overflow; temperature energy; overlap; cold lap; manganese; tandem GMAW;

    Sammanfattning : Tandem gas metal arc welding (GMAW) is a high productivity welding process which is appliedin many industries. However, a type of imperfection, known as cold lap, was revealed thatmostly accompanies the tandem GMAW process. LÄS MER

  5. 44. Structure, Dynamics and Phase Behaviour of Charged Soft Colloidal Dispersions

    Författare :Sofi Nöjd; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microgels; directed self-assembly; interaction potentials; scattering methods; confocal laser scanning microscopy; dielectric spectroscopy;

    Sammanfattning : Soft and deformable ionic microgels such as poly(N-isopropylacrylamide-co-acrylic acid), PNIPAM-co-AA, microgels have shown to be a versatile alternative to the already well-established hard sphere model systems. Their tuneable interaction potential makes them well suited as model systems to study the phase behaviour found for particles interacting via a soft isotropic potential. LÄS MER

  7. 45. Children's Living Conditions : Studies on Health, Family and School

    Författare :Sara Brolin Låftman; Jan O. Jonsson; Viveca Östberg; Anne H. Gauthier; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children; living conditions; well-being; family; health; school; Sweden; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : The present dissertation includes four empirical studies, each of which focuses on specific aspects of children’s living conditions. Study I analyses the association between young people’s social relations and health complaints using Swedish nationally representative survey data on 10- to 18-year-olds. LÄS MER
