Whereas the change of material properties due to change in the temperature can easily be realized, the coupling of the different energy sources is less obvious at a first glance. However, taking advantage of thermodynamics, the different couplings will almost automatically be taken care of. Therefore, when considering thermoplasticity, it is advantageous to make full use of thermodynamics, both wh
Popular Abstract in English In an ever energy hungry world and given the concerns about global warming, depleting reserves of fossil fuels and growing fuel prices, there is an urgent need for alternative renewable energy sources. Biogas production through anaerobic digestion in sync with other bio energy production technologies could replace or partially replace fossil fuels and hence curb greenhoAnaerobic digestion provides an array of positive environmental benefits such as reducing greenhouse gas emissions, replacing mineral fertilizers, producing renewable energy and treating waste. However, pitfalls in anaerobic digestion such as poor methane yields, process instability, process failure and regional shortages of feedstock have limited the full exploitation of the anaerobic digestion p
Biografier över samtliga avlidna präster i Domprosteriets kontrakt, Göteborgs stift 1620-1999, jämte biografiska data och bibliografier även för de levande. Bygger på ett mycket omfattande källkritiskt och historieteologiskt arbete och avspeglar församlingslivets utveckling. Ersätter Skarstedts herdaminne från 1800-talet.
The flow field generated by the flow into a jet engine air-intake, with near ground effects, is considered. The axial inflow in the neighborhood of the ground generates a system of unsteady vortices. Some of these vortices extend from the air-intake towards the ground. Some of these vortices are strong enough to dislocate and even lift small objects from the ground up to the air-intake. The dynami
How do readers interact with net papers? Does the new medium influence our way of searching for news? Does net-paper reading differ from newspaper reading? 12 users were asked to read 2 net-papers at their own pace. The aim of the study was partly to analyse reading behaviour on the Internet, partly to understand some of the underlying rationale and motivation of the behaviour. To achieve this aim
Many people have no doubts about the seriousness of environmental problems in the world. But the most important issue is to find the way in which these problems could be solved. Environmental problems are so complicated that it is not easy to find the right solution. It is important to change current `Western' and also growing `Eastern' consumption and production radically both from technological
Popular Abstract in Swedish Clostridium difficile-associerad diarré - aspekter på sjukhusepidemiologi och behandling Sjukhusutbrott av diarré med Clostridium difficile upplev's i Sverige och internationellt som ett betydande problem. C. difficile är en bakterie som normalt kan förekomma i tarmen. Under antibiotikabehandling förstör's den mikrobiologiska balansen i tarmen och C. difficile bakterieClostridium difficile is a spore-forming bacterium that causes antibiotic-associated diarrhoea and is responsible for hospital outbreaks of diarrhoea. In the first study, 173 consecutive isolates of C. difficile collected from 147 patients at Malmö University Hospital during 1995 were typed by AP-PCR to determine whether cross-transmission could explain the increased incidence of Clostridium diffi
En av de ständigt aktuella frågorna i den kommunala ekonomiska debatten är den kommunala resultatutvecklingen. Går den att påverka eller är kommuners situation allt för styrd av externa restriktioner? Syftet med denna studie är att inspirera och sprida erfarenheter till kommunala politiker och tjänstemän som har till uppgift att hushålla med kommunens resurser. Två övergripande frågor står i fokus
Popular Abstract in Swedish Järn är ett metalliskt grundämne som tillhör övergångselementen i det periodiska systemet. Den kemiska beteckningen är Fe (av det latinska ordet ferrum). Järn har visat sig vara ett väldigt viktigt ämne för i princip allt liv på vår planet. Främst finns det bundet till olika proteiner i form av järnsvavelkluster och hem. Hem är en liten molekyl som finns i de allra fleFerrochelatase catalyses the synthesis of heme by inserting Fe(II) into protoporphyrin IX. The structure of ferrochelatase from yeast has been determined (2.4 Å). The structure is homodimeric with each of the monomer made up of two Rossmann type domains with an active-site cleft between them. Metal binding studies with Co(II) and Cd(II) ions reveal the metal binding residues as being the His-Glu
Studies the origin of the Inventio Crucis legend: the historical events behind it as well as its textual sources and antecedents. A literary interpretation of the text is then attempted, showing that the legend is influenced by Jewish traditions and adversus Iudaeos treatises. Finally, the liturgical texts used to celebrate Inventio Crucis in the Middle Ages are surveyed. Three versions of the Lat
