    Sammanfattning : Background: Atrial fibrillation (AF) is the most common clinically significant arrythmia with a prevalence of approximately 3% in the general population. Less is known about the incidence of AF. In order to reduce the incidence of AF, it is of essence to identify modifiable risk factors for the disease. LÄS MER

  3. 3. Densities and Sizes of Self-assembled Quantum Dots Grown by MOVPE

    Sammanfattning : This thesis is based on results concerning the formation of semiconductor self-assembled quantum dots. The quantum dots have been grown by metal organic vapour phase epitaxy in the Stranski-Krastanow growth mode. LÄS MER

  4. 4. Litteraturhistoriskt undervisningsinnehåll – introduktion och respons

    Författare :Jonas Johansson; Jenny Folkeryd; Martin Karlberg; Anna Nordenstam; Uppsala universitet; []

    Sammanfattning : This study aims to develop knowledge about the teaching of literary history in upper secondary school. Sub-study I explores: What content is foregrounded when upper secondary school teachers of Swedish introduce literary history? And what significance can different teaching content have for sparking interest? Sub-study II explores: What teaching content sparks students’ interest in literary history? And what other aspects of the teaching spark their interest in literary history according to the students themselves? The study is framed by didactics and curriculum theory and also theories about interest and teaching. LÄS MER

  5. 5. Local adaptive pigmentation in Asellus aquaticus -effects of UV-radiation and predation regime

    Författare :Jonas Johansson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Marinbiologi; limnology; aquatic ecology; marine biology; Hydrobiology; Ekologi; Ecology; damselfly; perch; UV-avoidance; isopod; anti-predator traits; evolution; selective predation; limnologi; akvatisk ekologi; Animal ecology; Djurekologi;

    Sammanfattning : Pigmentation in the freshwater isopod Asellus aquaticus differed between two habitats. Asellus were lighter pigmented in stands of submerged stonewort vegetation, than in nearby reed stands. Moreover, Asellus pigmentation became lighter with time in recently established stonewort stands. LÄS MER
