Aerosol particles have always been present in the atmosphere, arising from natural sources. But it was not until recently when emissions from anthropogenic (man made) sources began to dominate, that atmospheric aerosols came into focus and the aerosol science in the environmental perspective started to grow. These sources emit or produce particles with different elemental and chemical compositions

Popular Abstract in Swedish Läs- och skrivfärdigheter är av stor betydelse i det moderna samhället. Dyslexi (läs- och skrivsvårigheter) är därför inte bara ett språkligt handikapp - det verkar också ha sociala konsekvenser som t.ex. högre arbetslöshet bland individer med dessa svårigheter. Tidigare forskning har bl.a. visat att personer med dyslexi har ett sämre verbalt minne och lägre självförtroReading and writing skills are of crucial importance in modern society. Therefore, dyslexia is a significant handicap, not only in respect of lexical skills and processing of language-based information - it appears to have social consequences as well, as evidenced for instance by the high frequency of dyslexics among long-term unemployed people. One major research problem is that the term dyslexia

The Epistle to the Hebrews has been an exceptionally significant text in Christian-Jewish relations. In particular, certain passages have been interpreted in ways that assume that Christianity supersedes Judaism. In this article it is argued that reading the epistle without presupposing supersessionism, Heb. will be acknowledged as one of those subject matters which, in the words of Nostra Aetate,

Boken behandlar språkutveckling och språkstörning hos enspråkiga barn. Först presenteras aktuella definitioner av språkstörning och ges en historisk översikt av ämnet. Därefter beskrivs fonologisk, grammatisk och lexikal utveckling hos barn med typisk språkutveckling samt ges en översikt av teoribildningen inom respektive område. Problem inom fonologi, grammatik och lexikon hos barn med språkstör

In this thesis, lipid biosynthesis is discussed focussing on the genes and enzymes involved in the final step of storage lipid synthesis, on the enzyme phospholipase A2, and on cell membrane lipid homeostasis. The investigation of lipid metabolism revealed that in Saccharomyces cerevisiae, there are four genes that are essential for the final step of storage lipid biosynthesis; ARE1, ARE2, DGA1, a

The interest in diffusion imaging with nuclear magnetic resonance techniques has increased during the last few years. The main reason is the possibility of early diagnosis of acute ischaemic stroke, at a time when conventional MR techniques and computerised tomography fail. The purpose of this study was to develop and evaluate methods for the measurement of water self-diffusion in vivo usin

Metabolomics is a rapidly growing research field. It aims for quantification of all the metabolites in a biological sample such as plasma, saliva, cerebrospinal fluid or cells. Because the metabolite levels in a biological sample are the end result of the regulatory processes in cells, metabolomics is a very powerful approach for characterisation of phenotypes. Metabolomics has been used to find d
