1. Tourette Syndrome and Tic Disorders in a Swedish School Population : Prevalence, Clinical Assessment, Background, Psychopathology, and Cognitive Function
Abstract : A total population of 4,479 children (7-15 years of age) attended school in Ludvika & Smedjebacken in 2000. All the school children and their parents were asked to fill in a questionnaire concerning different tics A three-stage procedure was used: tic identification, interview, and clinical assessment.

2. Microstructure of Alumina (Al2O3) Grown by Oxidation of FeCrAl Alloys and by Chemical Vapour Deposition
Abstract : This thesis consists of two parts: the detailed microstructure of (i) CVD alumina multilayer coatings, and (ii) alumina scales formed on three different FeCrAl alloys. The coatings and oxide scales were characterized by using analytical electron microscopy and different surface analysis techniques. READ MORE

3. Control of Wear-Resistance Properties in Ti-added Hypereutectic High Chromium Cast Iron
Abstract : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The wear resistance and mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). READ MORE

5. Aspects of microstructural evolution in chromium steels in high temperature applications
Abstract : In this thesis 9-12 % Cr steels, used for high-temperaturecomponents in fossil-fired power plants are considered. Thecreep strength of thees steels depend on their microstructurethat consists of a matrix of tempered lath martensite withdensely distributed precipitates. READ MORE
