General complementarity and the double-prism experiment

The interesting double-prism experiment of Ghose, Home, and Agarwal 5) has been suggested 5, 8, 16, 7, 6) as a challenge to Bohr´s views of complementarity. With the linguistic complementarity 14) as a general notion of complementarity, we analyze Bohr´s views of complementarity. We find that a careful formulation of Bohr´s wave-particle complementarity, with an explicit characterization of measur

Foam, Fire and Free Volume - Chemical and Physical Aspects of Porous Polymers

Popular Abstract in Swedish Bilsäten har genomgått en kontinuerlig utveckling ända sedan de först beskrevs år 1885. På den tiden kunde man läsa om vadderade läderbänkar, monterade på stora fjädrar, fastsatta i chassit på ”hästlösa vagnar”. När polyuretanskum först började tillverkas på 1950-talet introducerades de snabbt i bilsätena och dessa genomgick stora förbättringar. Skummen utgör idag en stAutomotive seating has been under continous development since it was described for the first time in 1885. At that time one could read about a “padded leather bench seat sitting on springs mounted directly to the frame of a horse-less carriage”. With the development of flexible polyurethane foam in 1950-1960 the seats were considerably improved and the traditional springs were eventually replaced

Indoor air quality in submarines

The next generation of conventional submarines will be submerged for several weeks, creating a need for regenerative air purification methods and new air monitoring instruments. Submarine air is a complex mixture of compounds, where the most obvious contaminant is metabolically produced carbon dioxide. Normal eight-hour occupational exposure limits are not applicable on a submarine, instead specia

Creation of a Nanometer-Scale Toolbox for Molecular Motor Transport-Circuits

This thesis presents studies of molecular motors in interaction with nm-scale structures, as well as the development of a set of tools that can be used for the construction of custom-designed nano-transportation systems. In our studies, we have used the latest nanoscale technology and combined this with advanced results from chemistry and biomedical sciences. We have succeeded in transferring bio

Dynamic speed adaptation based on information technology

In order to define critical situations in which speed adaptation is unsatisfactory a number of traffic safety researchers from 20 countries were asked to rate the seriousness of various situations. The proportion of injury accidents in the different situations were also considered. Expert judgements, the high proportion of injury accidents and the increased accident risks compared to "normal" cond
