1. 11. Personality and its complexity : An investigation of the Swedish version of the Temperament and Character Inventory

   Författare :Sven Brändström; Per-Olof Nylander; Sören Sigvardsson; Conny Nordin; Ada Zohar; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psychiatry; Psykiatri;

   Sammanfattning : In former days the descriptions of personality were based on typologies, reflecting the view that people do not change over time and so have a stable, life-long personality type. Later on exclusive categories were created, but during recent times the understanding of personality has changed due to more dimensional and dynamic thinking. LÄS MER

3. 12. Diatom-rich sediment formation in lakes

   Författare :Petra Zahajská; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon; silica; diatom; biogenic silica; lake; sediment; stable Si isotopes; Ge Si; Yellowstone; Northern Sweden;

   Sammanfattning : Unicellular photosynthetic golden algae called diatoms are one of the most abundant silicifying organisms. Diatoms take up silicon and build their frustules, in the form of biogenic silica (BSi), which have high preservation potential, and thus are found in sediments. LÄS MER

   Författare :Martin Westberg; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phylogeny; ITS rDNA; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; distribution; anatomy; Candelariaceae; Candelariella; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

   Sammanfattning : The lichen genus Candelariella comprises crustose to small squamulose members of the family Candelariaceae. The genus currently includes c. 50 species world-wide but few studies have treated the taxonomy within this group. In the present thesis the taxonomy of the genus in western North America is treated.

5. 14. Phenotypes and genotypes in families with hereditary tapetoretinal degenerations

   Författare :Vesna Ponjavic; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripherin.; rhodopsin; cone-rod dystrophy; retinitis pigmentosa; choroideremia; central areolar choroidal dystrophy; mutation screening; full-field electroretinography; Phenotype; genotype; Ophtalmology; Oftalmologi;

   Sammanfattning : The purpose of the study was to characterise the phenotype with emphasis on electroretinography in four different types of hereditary retinal degeneration and to correlate it to a genotype when possible. Two methods were used: full-field electroretinography for objective assessment of retinal function and mutation screening of blood samples for detection of gene alterations. LÄS MER
