  2. 21. Risk factors for disability pension : studies of a Swedish twin cohort

    Author : Åsa Samuelsson; Karolinska Institutet; Karolinska Institutet; Karolinska institutet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background & aims: Mental disorders are today the major diagnosis behind newly granted disability pensions (DP) in the Western world. Yet, studies of risk factors for DP due to mental diagnoses are scarce, are often based on small or selective samples, and have a cross-sectional design, or short follow-up. READ MORE

  4. 22. Disentangling Lecania

    Author : Rikke Reese Næsborg; Leif Tibell; Stefan Ekman; Bengt Oxelman; Christian Printzen; Uppsala universitet; []
    Keywords : Biology; Crustose lichens; Phylogeny; Taxonomy; Morphology; New species; Phylogenetic diversity; Rare species; ITS; mt-SSU; RPB2; IGS; Biologi; Lecania; Ramalinaceae;

    Abstract : This thesis focuses on phylogenetic, taxonomic, ecological, and conservation aspects of the crustose lichen genus Lecania (Ramalinaceae, lichenized Ascomycota). Lecania has previously been defined on basis of relatively few morphological characters, and the genus had never been treated in molecular phylogenies. READ MORE

  5. 23. Phylogeny and Taxonomy of Polyblastia and allied taxa (Verrucariaceae)

    Author : Sanja Savić; Leif Tibell; Bengt Oxelman; Martin Grube; Uppsala universitet; []
    Keywords : Biology; Phylogeny; Taxonomy; ITS; LSU; RPB1; Nomenclature; Biologi; Polyblastia; Verrucariaceae; Sporodictyon; Atla; Thelidium; Verrucaria; Staurothele; Trimmatothele;

    Abstract : Polyblastia A. Massal. is a genus of lichenized fungi belonging to Verrucariaceae (Ascomycota). Traditional classification heavily rested on a few cardinal characters, primarily ascoma structure and spore morphology, but the delimitation of Polyblastia was problematic. READ MORE

  6. 24. Tribology of stamping : the influence of designed steel sheet surface topography on friction

    Author : Daniel Wiklund; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel sheet; tribology; surface topography; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.

  7. 25. Quantitative genetics of wood quality traits in Scots pine

    Author : Irena Fundová; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wood quality of commercial tree species is important for many wood processingindustries and thus should be considered for inclusion in forest tree improvementprograms. This thesis evaluated the suitability of various proxy methods for rapid andnon-destructive assessment of wood quality traits on standing trees of Scots pine and thepotential for genetic improvement of different wood quality traits through recurrentselective breeding.
