6. Release and transport of drugs in some complex and interacting systems
Sammanfattning : Drug formulations come in many forms, some intended for direct and immediate action and others aiming at a controlled manner of drug delivery. Viewed in a more general way drug transport often involves charged units, it takes place in a medium which in many respects must be considered complex - to some degree even reactive. LÄS MER
7. Stopover behaviour in migratory songbirds: timing, orientation and departures
Sammanfattning : Songbird migrants use stopovers between flight bouts to rest and refuel for the upcoming flights. Behaviours affecting where, when and how long to stay at stopover sites will affect how successful the overall migration will be, which has significant consequences for the overall fitness and mortality of the birds.

8. Charge Accumulation in Hybrid High Voltage Insulation
Sammanfattning : This thesis deals with the novel idea of controlling the electric stress or field distribution in a hybrid air - solid-dielectric high voltage insulation by promoting accumulation of surface charges on the internal interfacial layers in the combined (hybrid) dielectric structure. Primarily, applications are expected to be found in high voltage dc systems and as a method to improve the resistance against insulation failure by overvoltages, e. LÄS MER
9. Temporal relationships between fish-eating birds and their prey in a north Swedish river
Sammanfattning : The seasonal and diel feeding habits of the goosander, Mergus merganser, the red-breasted merganser, M. serrator, gulls (Larus canus, L. argentatus and L. fuscusj and terns, Sterna hirundo/paradisaea were studied at 64V05'N. LÄS MER
10. Microbially mediated formation of birnessite-type manganese oxides and subsequent incorporation of rare earth elements, Ytterby mine, Sweden
Sammanfattning : Microbes exert extensive control on redox element cycles. They participate directly orindirectly in the concentration and fractionation of elements by influencing the partitioningbetween soluble and insoluble species. LÄS MER
