Fuel cells (FCs) are promising as an energy producing device, which at this stage of development will require extensive analysis and benefit from numerical modeling at different time- and length scales. COMSOL Multiphysics is used to describe an intermediate temperature solid oxide fuel cell (SOFC). Governing equations for heat, gas-phase species, electron, ion and momentum transport are implement
The latest technology and architectural trends have significantly improved the use of a large variety of glass products in construction which, in function of their own characteristics, allow to design and calculate structural glass elements under safety conditions. Both monolithic as well as laminated glass can be used for these proposals. In the case of laminated elements interlayers of polymers
Skandaler genererar ett intensivt moraliskt indignerat socialt klimat. Inte sällan innefattar skandalerna en form av medierättegångar, vilket korrigerar Foucaults teser om det dolda straffet. För de anklagade, som uppfattar sig som orättvist utpekade, kan konsekvenserna bli drastiska, samtidigt som de har svårt att återupprätta sitt anseende. I denna artikel diskuteras sådana "skandaloffers" kamp.
Orientation for insects in olfactory landscapes with high semiochemical diversity may be a challenging task. The partitioning of odor plumes into filaments that are interspersed with pockets of ‘clean air’ may help filament discrimination and upwind flight to attractive sources in the face of inhibitory signals. We studied the effect of distance between odor sources on trap catches of the beetle,
Drawing on the expertise of a distinguished international team, this book contains 200 recent papers in the peer-reviewed literature that will affect the practice of physicians managing osteoporotic patients. Each paper is summarized, reviewed, and placed in clinical context. Coverage includes the underlying causes of osteoporosis and the latest differing views on prevention and non-pharmacologica
The flagellate Euglena gracilis shows rhythms in phototaxis and cell shape changes between oblong and round. Artificial UV-B radiation of 0.5 W m-2 caused a loss in phototaxis, but the peak of activity occurred at the same time as for control cells. The transition from round to oblong cell shape was slower after UV-B radiation, but the amplitude between the roundest and the most oblong cell shape
The temperature distribution in a concrete structure varies due to complex interactions with the surrounding climate. Solar radiation, air temperature, wind speed and long-wave radiation all affect the temperature in the material, and may cause movements in the longitudinal and transversal directions. If these movements are restrained, stresses and strains can be induced which may contribute to cr
