We report results from a subset of an extensive study of the performance of blind persons in different haptic environments. Test tasks included in the study were recognition of simple geometrical objects, realistic VRML models, mathematical surfaces, a si
Immunotherapy, which involves strategies to activate, enhance or redirect immune responses to achieve long-lasting immunity, has the potential to play an important role in the treatment of a variety of diseases. This thesis, based on four original papers, highlights different approaches to modulate immune responses by specific targeting of antigen-presenting cells. The first two studies focuses o
Due to high installation costs and relatively low output, the active use of solar energy is limited. The output from a collector can be improved e.g. by using a selective absorber, AR-treated cover glass or transparent insulation. The output/cost ratio can also be improved by the use of reflectors. The performance of a collector depends highly on the incidence angle dependent optical efficiency. I
Wind power is seen by many observers as an important part of the transition to a sustainable energy system, since it does not contribute to the environmental problems connected with dominating energy forms such as fossil fuel, nuclear power and large-scale hydro power. At the same time wind power has some characteristics that makes it a special challenge for land use planning. In Sweden, where win
The aim of this work, which will be part of the PhD work of the author of this report, was to evaluate the precision and accuracy expected from bomb-pulse dating of human tissue, focusing on the uncertainties introduced by variation in 14C in the human diet. Such variations may be caused by releases from nuclear installations, hospitals and laboratories using 14C, use of fossil fuels as well as va
InvitedPaper presented at conference/seminar on difficult fieldwork, discusses compromises that ethnographers will have to make as their fieldwork becomes more fragmented and their study objects more suspicious, especially when studying elites; the possibility of any solidarity or empathy with the people we study may be declining.
