Simultaneous formaldehyde and OH PLIF have been applied in a direct-injected HCCI engine. The engine is a 0.5 l single-cylinder optical engine equipped with EGR system. PLIF measurements were performed with the engine run with two different fuels of low and high volatility, respectively. Different ratios of EGR were also examined. The aim of the study was to investigate how fuels with different vo

Popular Abstract in Swedish En magnetkamera kan med hjälp av diffusionsviktad bildtagning användas för att avbilda hjärnans nervsystem. Denna teknik kan utnyttjas för studier av hur hjärnans delar är sammankopplade, men även för att indirekt mäta egenskaper hos hjärnans mikrostruktur. Detta avhandlingsarbete vidareutvecklar de biofysikaliska modeller och mätmetoder som används för denna indirekta Diffusion MRI is widely used to study brain structure in vivo. While this technique is often applied to investigations of brain connectivity, it can also be used to infer specific information about the tissue microstructure; for example, to estimate the axon diameter. In the present work, the role of tissue microstructure and water exchange in biophysical models employed in diffusion MRI was inves

Law and its countless legal, academic, professional and institutional manifestations, all being intrinsically social, fall within the scope of sociological inquiry. It is, therefore, not surprising if some sociologists and jurists have tried to bring the benefits of sociological ideas to legal thought and practice. Introducing sociological insights into law, a feasible and useful project in theory

Popular Abstract in Swedish Blödande åderbråck i matstrupen - en jämförande studie mellan kirurgisk shunt och lokal behandling Patienter med skrumplever riskerar många komplikationer. Den mest fruktade är blödning från oesofagusvaricer, dvs åderbråck i matstrupen. Fyrtio procent av patienterna avlider om de inte får behandling. Anledningen till att patienter med skrumplever (cirros) utvecklar oesThis thesis is aimed at evaluating the clinical results of two treatments in patients with bleeding oesophageal varices; the mesocaval interposition shunt (MI shunt) and repeated endoscopic sclerotherapy (ST). 24 patients were randomised to MI shunt and 21 patients to the ST group (mean age 51.6?9.2 and 53.6?10.5 years). Complications include shunt occlusion in 4 %, oesophagitis in 33 % and oesoph

This dissertation investigates nanomagnetism in small transition metal clusters and the diluted magnetic semiconductor (Ga,Mn)As. We derive quantum mechanical models aimed at a realistic description of the low energy physics in these systems. The main focus of the work presented is on magnetic anisotropy, the effects of spin-orbit interaction and quantum geometric phases. The first part of the the

Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. The two nuclei together provide the possibility to explore mirror

Popular Abstract in Swedish Många framsteg har gjorts inom bioteknik de senaste decennierna. Idag kan vissa sjukdomar fastställas redan på DNA-nivå och viktiga läkemedel samt tvättmedelskomponenter tillverkas industriellt med hjälp av gentekniska tekniker. Kostnaden för de gentekniska produkterna ligger till stor del i själva uppreningsprocessen. Forskningen i denna avhandling har gjorts med avsikThis thesis describes the possibility of using hydrophobic peptide tags as tools for bioseparation and for the investigation of recombinant proteins. The hydrophobicity of a protein can easily be changed by minor modifications, such as fusions of tyrosine-containing peptides. The fusion tags may also increase both stability and expression of the fusion protein. Furthermore, a protein library with

A numerical model of nearshore waves, currents and sediment transport was developed. The wave conditions were calculated by the Modified-EBED model and the surface roller was modeled following the approach of Daily and Brown (1995) with an enhancement of the energy flux term in the alongshore direction. Nearshore currents and wave setup were determined by the depth-averaged momentum equations toge
