  1. 1. Migratory behaviour of Baltic salmon (Salmo salar L.) : adaptive significance of annual cycles

    Författare :Torleif Eriksson; Lars-Ove Eriksson; Kees Groot; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Migratory behaviour; annual cycles; Baltic salmon; Salmo salar; annual time program; swimming behaviour; mortality; maturity; life history;

    Sammanfattning : This thesis evaluates the adaptive significance of annual cycles on the migratory behaviour of Baltic salmon (Salmo salar L.). The studies have included field experiments as well as laboratory studies gf maturity and migratory behaviour patterns of smolts and postsmolts mainly from the Angerman river population. LÄS MER

  3. 2. Dust mite allergens : cloning, characterisation and T-cell responses

    Författare :Tove L J Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The number of allergens that have been cloned has increased dramatically during the last 10 years, and today, over 400 allergen sequences are available in the databases. In addition, at least 15 dust mite allergens have been characterised. LÄS MER

  4. 3. Studies on Parental Leave and Co-residence using Swedish Register Data

    Författare :Helen Eriksson; Ann-Zofie Duvander; Elizabeth Thomson; Linda L. Haas; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sociologisk demografi; Sociological Demography;

    Sammanfattning : Understanding the two primary life-course events that create and accelerate gender inequality within the couple -- the transition to parenthood and parental separation -- may ameliorate their far-reaching consequences over the life-course in multiple domains of life. This thesis includes four studies on various aspects of these life-course events. LÄS MER

  5. 4. Control Aspects of Complex Hydromechanical Transmissions : with a Focus on Displacement Control

    Sammanfattning : This thesis deals with control aspects of complex hydromechanical transmissions. The overall purpose is to increase the knowledge of important aspects to consider during the development of hydromechanical transmissions to ensure transmission functionality. LÄS MER

  7. 5. Musculoskeletal Biomechanics in Cross-country Skiing

    Författare :L. Joakim Holmberg; Anders Klarbring; Hans-Christer Holmberg; Anders Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Why copy the best athletes? When you finally learn their technique, they may have already moved on. Using muscluloskeletal biomechanics you might be able to add the "know-why" so that you can lead, instead of being left in the swells. LÄS MER
