    Sammanfattning : Controllable macromolecular gating between nanoscopic compartments is of high interest for single molecule studies of biological macromolecules. By definition, a good macromolecular gate should completely stop biomolecules, such as proteins, from crossing between compartments in its closed state while letting them pass in its open state.

  4. 8. Neonatal hip instability. The anterior-dynamic ultrasound method. Population screening and re-evaluation of some aetiological factors

    Författare :John E. Andersson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hip dislocation congenital; ultrasound examination; breech presentation; delivery hormone;

    Sammanfattning : To evaluate neonatal hip instability, the values for the physiologically normal movement of the femoral head by provocation were determined by an anterior-dynamic ultrasound method. The maximal movement of the femoral head with the acetabulum at provocation was 6.0, 6.6 and 6. LÄS MER

  5. 9. Catch and effort from a recreational trolling fishery in a large lake

    Författare :Anders Andersson; John Piccolo; Larry Greenberg; Ian Cowx; Karlstads universitet; []

    Sammanfattning : Over recent decades recreational fisheries have grown substantially throughout the world. Despite this increase, catches from recreational fisheries have often been ignored in fisheries management, although this is now being remedied. LÄS MER

  7. 10. Empirical Essays on Railway Infrastructure Costs in Sweden

    Författare :Mats Andersson; Lars-Göran Mattsson; John Preston; KTH; []
    Nyckelord :Railways; Infrastructure; Marginal Costs; Maintenance; Renewal; Econometrics; Panel Data; Survival Analysis; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The subject of this thesis concerns pricing the use of transport infrastructure. We are empirically investigating the relationship between railway traffic volumes and infrastructure management costs. More specifically, we are interested in estimating the change in infrastructure management costs from marginal variations in traffic volumes, i.e. LÄS MER
