This thesis demonstrates the usefulness of sedimentary pigments as biomarkers of environmental change in estuarine systems and as biomarkers in lakes in relation to climate change. These are two fields where sediment pigment records as measured by high-performance liquid chromatography (HPLC) are emerging areas of study. A detailed study was undertaken to examine the effects of different storage o
In patients with drug resistant partial epilepsy, who are under consideration for epilepsy surgery, interictal and ictal EEG recorded with extracranial electrodes plays an important role in the localisation of the seizure onset area. During the past years, methods have been developed, which can be used to estimate the location of the source of epileptiform activity in the brain from extracranial E
This thesis summarises experimental results on the molecular spectroscopy of gas phase molecules excited by synchrotron radiation in the VUV and soft X-ray regions. We have used three different detection techniques, photon in- duced fluorescence spectroscopy, photoionisation mass spectroscopy and near edge X-ray absorption fine structure spectroscopy to study molecular deu- terium, hydrogen sulp
Med skolpersonalens kunskaper och inställningar som utgångspunkt har förutsättningarna för drogpreventivt arbete inom grundskolan undersökts. För att uppnå en relativ bredd har skolor av skiftande storlek och socioekonomiska upptagningsområden i olika sydsvenska kommuner ingått i studien. Materialet bygger på intervjuer, enkäter och fokusgrupper som kompletterats med litteraturstudier. Resultatet
Popular Abstract in Swedish Hjärt- och kärlsjukdomar som till exempel åderförkalkning utgör en av världens vanligaste dödsorsaker. I den här avhandlingen har vi utvecklat olika metoder som med hjälp av bildanalys ger värdefull information om kärlväggen i syfte att förbättra kunskapen om artärer och framförallt åderförkalkning. I avhandlingen presenteras fem olika metoder som alla är baserade på biAtherosclerosis is one of the major causes of death in the world. It is an inflammatory disease in the arteries which causes a gradual increase in arterial wall thickness and stiffness. Eventually a plaque could be formed, protruding into the artery and partially occluding the blood flow. Rupture of such a plaque could cause cardiac infarction or stroke. This dissertation revolves around finding b

The work has involved a search for insights into the "detail" of the path-dependant nature of a country’s movement away from oil. Three main strands of work have been involved. Firstly, an examination of the implications of a recent Swedish policy announcement that the country will pursue independence from fossil fuels – with particular focus on oil replacement and flow on effects to the bioenergy
