Popular Abstract in Swedish Joniserande strålning- en introduktion (Ionizing radiation- Introduction in Swedish) 13.1 Storheter och enheter Effekten av strålningen från ett radioaktivt ämne eller röntgenapparat kallas stråldosen, eller egentligen den effektiva dosen , och anges i enheten sievert (Sv). Aktiviteten av ett radioaktivt ämne anges i enheten becquerel (Bq) och anger antal sönderfallanIn this thesis quantitative analyses of radionuclide concentrations in bioenergy fuels such as peat, wood chips and straw are presented. For comparison a brief description is included of radionuclide concentrations and radiation doses from other sources of power and also from some industrial applications. Radiation is a natural phenomenon and radionuclides occur naturally. The first man-made spre

In the RUNES project a disaster relief tunnel scenario is being developed in which mobile robots are used to restore the radio network connectivity in a stationary sensor network. A component-based software development approach has been adopted. Two components are described in this paper. A localization component that uses ultrasound and dead reckoning to decide the robot positions and a collision

Since the 1990s, it has often been argued that the earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, for instance, with its largely depleted resources and an indigenous population which almost became extinct in the 19th century, has been seen as a microcosmic warning about what may happen to our entire planet. However

The present article reports results from tests performed to investigate different designs of a scrolling function used to make it possible for the user to navigate a virtual environment larger than the limited workspace of the haptic device. A preliminary

Abstract in UndeterminedThe secreted protein Dickkopf-1 (Dkk1) is an antagonist of canonical Wnt signaling, expressed during fracture healing. It is unclear how it is involved in the mechanical control of bone maintenance. We investigated the response to administration of a Dkk1 neutralizing antibody (Dkk1-ab) in metaphyseal bone under different loading conditions, with or without trauma. In this
