The interest for the design of life environments for persons with dementia is growing stronger among architects, engineers, social scientists and those responsible for housing and health care planning. This development is connected to the enlarged group of people that become afflicted by this disease and to the fact that a safe environment is proved to be very important for their well-being as wel

A theory is presented for the service life of concrete exposed to frost action. It is based on a separation of the frost resistance problem in two parts. Part 1, that is only a function of the material itself, and which is expressed in terms of a critical water content, or a degree of saturation, which is a "fracture value" being almost independent of the external conditions (except for the lowest

The Relativistic Heavy Ion Collider (RHIC) has made it possible to study hadronic matter under unprecedented conditions in terms of temperature and energy density. Global variables are essential for the characterization of nuclear collisions at ultra-relativistic energies. The PHENIX experiment has several detectors which provide information about the global properties and hence the initial condit

Ion beam analysis techniques are now well established as research tools for a broad range of multidisciplinary scientific fields. The ability to focus an ion beam down to micrometer size has expanded and strengthened the capability of IBA techniques to a higher level. A new field “Nuclear microprobe (NMP) analysis” has been developed over the past decades, in which most IBA techniques are used and

In the evolution of bird migration, partial migration is assumed to be an important intermediate step between migration and residency. Partial migration is characterised by the existence of both migratory and resident individuals in a given population. Compared to regular migration, relatively little is known about partial migrants and their migratory performances. In my thesis, I have studied th

Leken med låtsaskompisar kan vara en medveten skapandeprocess och ett äventyr in i möjligheternas och omöjligheternas värld. För att barn ska utvecklas till kreativa vuxna behöver de stimuleras att leka fantasilekar. Kreativitet handlar om att se nya möjligheter hos oss själva och den verklighet och de ting vi har omkring oss. Geniers kreativitet genererar banbrytande processer eller produkter, me

Six plutonium-containing particles stemming from Runit Island soil (Marshall Islands) were characterized by non-destructive analytical and microanalytical methods. Composition and elemental distribution in the particles were studied with synchrotron radiation based micro X-ray fluorescence spectrometry. Scanning electron microscope equipped with energy dispersive X-ray detector and with wavelength
