Popular Abstract in English The world’s resources of fossil fuels are rapidly being depleted, and we now know that the combustion of these fuels leads to the emission of greenhouse gases resulting in climate change. It is therefore imperative that we develop renewable sources of fuel. The production of bioethanol in Brazil is the best example today of the introduction of a renewable fuel on a largLignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. Residues for forestry and agriculture are particularly interesting since they result from crops with established cultivation procedures and technology for harvest and transportation are alr

Within the Eriksonian identity tradition, exploration of different life domains is crucial to identity formation. This is a process supposed to start during adolescence and develop in a social context. Most of the adopted children in Sweden, now in adolescence, are adopted from countries outside of Europe, which means that they neither share their biological nor ethnical roots with their adoptive

The presented study deals with a specific rerouting strategy for protecting traffic flows in communication networks called Flow Adjustment Routing. The strategy is designed to handle partial link failures. We present two variants of the strategy and analyze their pros and cons. We show that the initial strategy is not directly implementable to cope with severe link failures such as total link fail

Europeans have long taken a relaxed approach to due process requirements. Mere formalities should not prevent an efficient implementation of competition law, but rather be practical and foreseeable. With the Lisbon Treaty things are changing. A fair process and equality of arms based on fundamental human rights stipulations require that procedural safeguards are ensured. Recent case law developmen

Popular Abstract in Swedish Marsupialia (pungdjur) delas in i 280 nu levande arter, som är uppdelade i 19 familjer och sju ordningar. Släktskapet mellan de sju ordningarna har studerats på molekylär nivå på grundval av mitokondriella genom som sekvenserats i sin helhet. Pungdjur, jämte placentala (moderkaks-) däggdjur och kloakdjur, utgör de nu levande representanterna för klassen däggdjur. PungdjThe relationships of the mammalian infraclass Marsupialia have been investigated by phylogenetic analysis using completely sequenced mitochondrial genomes. The organisation and structure of the marsupial mitochondrial genomes deviates from the general mammalian structure. Several features, not known from other mammalian mitochondrial genomes have been shown to be present in all seven living marsup

This chapter addresses the increasingly important issue of effective addressing, object location and presence notification in networks with no infrastructure and dynamically changing environments. This chapter presents Calto, an architecture comprising presence concepts from Second and Third Generation Mobile networks, Instant Messaging Systems subscriber services, and distributed DNS style functi

The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curved surfaces and formation of dust have been studied. Typical are stick slip behavior and threshold stress levels for formation of dust. The emission of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, micr

The development towards total offers; integrated product and service offers, is a trend in industry, particularly in business to business relations. This strive towards more extended offers can be noticed in a wide range of companies from different branches, and it has important implications on management. Today there is no established method available to handle the extended risks associated with

The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. A special case of bubble transport is the cavitation phenomenon, which mainly has a negative effect on the performance of
