Popular Abstract in English The global energy consumption is increasing regularly due to the increased population and economic development. In contrast the primary energy sources, fossil fuels, are declining substantially. The combustion of fossil fuels contributes to the global climate change via greenhouse effects. To minimize these negative effects a carbon-neutral energy production is demandedThe electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to ele

Popular Abstract in Swedish Hem är en liten molekyl som förekommer som aktiv grupp i många viktiga proteiner, t.ex. hemoglobin, katalas och cytokromer. De hem-innehållande proteinerna är livsnödvändiga för alla djur och växter, samt många bakterier. Kemiskt sett, är hem en porfyrin (en annan känd porfyrin är klorofyll) som innehåller en järn-jon. Bakterien Enterococcus faecalis är en vanlig invånThe gram-positive bacterium Enterococcus faecalis is a commensal organism, often found in the gut of humans and other animals. It can cause opportunistic disease and it frequently causes nosocomial infections. Treatment of such infections is often impaired by this organisms broad intrinsic and acquired resistance to antibiotics. E. faecalis uses homo-lactic fermentation for energy production. Work

The main idea of this paper is to use distances between camera positions to recover the trajectory of a mobile robot. We consider a mobile platform equipped with a single fixed camera using images of the floor and their associated inter-image homographies to find these distances. We show that under the assumptions that the camera is rigidly mounted with a constant tilt and travelling at a constant

This compilation should be viewed as a kind of prolegomena to a history of interpolation. Three letters from Mischa Cotlar, Antoni Zygmund and Olof Thorin from c. 1980 are reproduced. Thorin's letter is given in translation. These letters were written as a reply to an inquiry by the editor/translator. It is remarkable that while Thorin spent his whole professional life as an actuary, neither of hi

In this paper we investigate partial response signaling (PRS) systems that are intended to operate close to capacity. We show that finding PRS systems with maximal capacity is a rather easy optimization task. We give an alternate way of defining bandwidth for PRS systems based on capacity considerations; this differs considerably from the traditional method based on transmission power. Practical P

Popular Abstract in Swedish Vår kropp består av en till synes oändlig mängd individuella celler. För att alla dessa celler skall kunna fungera som en helhet måste de meddela sig med varandra. För att en cell i tån ska kunna känna av vad som händer i knät så har den bland annat receptorer på sin yta. Receptorer är proteiner som sitter förankrade i cellens yttre skal, i cellmembranet. Receptorns enaInformation about extracellular proteolytic activity is transduced to the cell by a transmembrane G-protein coupled receptor subfamily. These receptors are activated by proteolytic cleavage in the extracellular amino-terminal domain and are thus termed proteinase-activated receptors (PARs). The second member of this subfamily, PAR-2, is activated by trypsin-like proteinases, however the physiologi
