Cloud computing has recently received considerable attention, as a promising approach for delivering ICT services by improving the utilisation of data centre resources. On the other hand, the increased usage of ICT, jointly with the increased cost of energy, make designing and managing data centres with energy efficient strategies a crucial and strategical problem. In the literature there are man
Spectroscopic investigations of highly charged ions have been performed in the VUV, UV and visible spectral regions using mainly the beam-foil technique. New 2s22px3l levels have been established in N and O-like Si and S, together with many transitions between these levels. Several of these lines have also been identified in the solar corona spectra recorded by the SUMER/SOHO instrument. In Mg-lik
Experiments on a modern DI Diesel engine were carried out: The engine was fuelled with standard Diesel fuel, RME and a mixture of 85% standard Diesel fuel, 5% RME and 10% higher alcohols under low load conditions (4 bar IMEP). During these experiments, different external EGR levels were applied while the injection timing was chosen in a way to keep the location of 50% heat release constant. Emissi
Abstract Purpose Treatment with blood pressure lowering drugs may reduce morbidity and mortality. However, the efficacy and effectiveness may differ between antihypertensive agents. The current investigation aimed to compare mortality and cancer incidence in hypertensive patients treated with calcium channel blockers (CCB) or with other antihypertensive drugs (AHD). Methods All patients in two o
This study examines the management of used mobile phones in the United Kingdom between 2005 and 2008. It shows that the replacement cycle for mobile phones got shorter during the period due to heavy handset subsidies given by mobile network operators. The planned obsolescence presented a business opportunity for the exports of used phones to developing countries. However, the collection for re-use
This paper discusses the results of a time-dynamic analysis of the possible effects of government and utility-sponsored energy-efficiency programs on electric energy use in Swedish commercial buildings. In the study, which includes efficient lighting, improvements in ventilation, commercial cooling and cooking, we use energy scenarios to analyse how policy measures can effect future energy demand.
Popular Abstract in Swedish På grund av befolkningsutvecklingen de närmaste åren kommer långt fler äldre människor än idag att bo kvar i vanliga bostäder, även om de särskilda boendeformerna byggts ut i snabb takt. För att underlätta kvarboende måste den fysiska boendemiljön motsvara de krav som ställs på grund av åldersförändringar och då hjälpbehov uppkommer. Arbetsterapeuter har, bl a genom erfThe general aim of this thesis was to explore relationships between functional capacity, environmental factors, everyday activity, and health in the elderly population. Initially, the Enabler, an instrument for assessment of the physical home environment's accessibility, was translated to Swedish and revised, and tested for reliability and validity. Further, a systematic random sample of individua
Wild bank voles (Clethrionomys glareolus) may develop diabetes in laboratory captivity. The aim of this study was to test whether bank voles develop type 1 diabetes in association with Ljungan virus. Two groups of bank voles were analyzed for diabetes, pancreas histology, autoantibodies to glutamic acid decarboxylase (GAD65), IA-2, and insulin by standardized radioligand-binding assays as well as
Popular Abstract in Swedish Denna avhandling handlar om utveckling och tillämpning av metoder för jonstråleanalys av lätta ämnen (lättare än ungefär aluminium), framförallt vid en nukleär mikrosond. Vid en nukleär mikrosond accelereras tunga partiklar, t.ex. protoner, av en partikelaccelerator och fokuseras av ett speciellt magnetiskt linssystem ned till en storlek av ungefär 1 mikrometer. Denna sThis thesis treats the development of Ion Beam Analysis (IBA) methods, principally for the analysis of light elements at a nuclear microprobe (NMP). The light elements are in this context defined as those with an atomic number Z of less than approximately 13 (aluminium). The work reported is to a large extent based upon multiparameter methods. Several signals are acquired simultaneously, and the d
Climate change is already impacting species around the world. Although most focus has been on the effect of temperature, changes in climatic variables other than temperature are also expected to drive biological change. Current models suggest that ectotherms, such as reptiles, will be strongly affected by climate change; however, data from natural populations are rare. Here, we use extensive data
A high fat intake, together with an inability to match lipid utilization of a high-fat intake, is correlated with obesity in man. In this review enterostatin, a peptide, which specifically reduces fat intake, is described. Enterostatin is formed in the intestine by the cleavage of pancreatic procolipase, the remaining colipase serving as an obligatory cofactor for pancreatic lipase during fat dige
Popular Abstract in Swedish Ateroskleros är en sjukdomsprocess vars grundläggande utveckling i blodkärlens väggar sannolikt börjar flera decennier innan insjuknandet i infarkt eller slaganfall inträffar. Som svar på endotelskada, inflammatoriska mediatorer eller tillväxtfaktorer i kärlet kommer glatta muskelceller att dela sig, migrera in mot blodbanan och börja syntetisera en helt ny uppsättning Smooth muscle cells (SMCs) in the vessel wall contract to regulate blood flow and pressure, a function essential for normal circulation through tissues. On the other hand, migration and proliferation of SMCs are important factors in vascular disease, such as atherosclerosis and restenosis following surgical dilatation. The conversion of the SMC to this role is marked by a modulation from contracti
