1. 1. Studies on metals in motor neuron disease

   Författare :Per M Roos; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : A slow but steady increase in neurodegenerative disorders has been noted in recent decades. Degenerations in the nervous system are found in Alzheimer's disease, Parkinson's disease and motor neuron diseases. Amyotrophic lateral sclerosis (ALS) is the most common of the motor neuron diseases. LÄS MER

3. 2. Daylighting Systems : Development of Techniques for Optical Characterization and Performance Evaluation

   Författare :Annica M. Nilsson; Arne Roos; Claes-Göran Granqvist; Marie-Claude Dubois; Michael Köhl; Uppsala universitet; []
   Nyckelord :Optical spectroscopy; integrating sphere; ray tracing; light scattering; window physics; Venetian blinds; core daylighting; optical characterization; Teknisk fysik; Engineering Science;

   Sammanfattning : Successful integration of daylighting systems requires the ability to predict their performance for given climates. In this dissertation, a bottom-up approach is applied to evaluate the optical performance of a selection of daylighting systems. LÄS MER

4. 3. The development of resource polymorphism – Effects of diet, predation risk and population dynamical feedbacks

   Författare :Jens Andersson; Lennart Persson; André M. De Roos; Umeå universitet; []
   Nyckelord :body shape; diet; geometric morphometrics; phenotypic plasticity; population dynamics; predation risk; resource polymorphism; size structured populations;

   Sammanfattning : This thesis deals with the evolution of individuals within a species adapted to utilize specific resources, i.e. resource polymorphism. Although a well-known phenomenon, the understanding of the mechanisms behind is not complete. LÄS MER

5. 4. Preparation and Characterisation of Sputtered Titanium- and Zirconium Nitride Optical Films

   Författare :Kent Andersson; Arne Roos; M. Georgson; Uppsala University Department of Technology Solid State Physics Group; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Multilayered interference coatings based on titanium- and zirconium nitride and designed for solar control have been prepared using reactive d c magnetron sputtering. Preparation effects and degradation mechanisms were investigated. It was shown that the quality of the nitride strongly depends on the degree of crystallinity in the underlying oxide. LÄS MER

7. 5. Nationens styvbarn : Judisk samhällsintegration i några Norrlandsstäder 1870-1940

   Författare :Per Hammarström; Torkel Jansson; Lars M Andersson; Laura Kolbe; Lena Roos; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; History; Historia; Judar; Historia; 1800-talet; 1900-talet; Sverige; Norrland; Sundsvall; Sverige; Nationalism; Nationell identitet; Minoriteter; Antisemitism; Sverige; Samhällsintegration; Socialhistoria; Lokalhistoria; historia; History; History of religion;

   Sammanfattning : Syftet med denna avhandling är att undersöka vilken ekonomisk och social ställning den judiska minoriteten intog i det svenska samhället under perioden 1870 till 1940. Tidigare forskning har riktat stor uppmärksamhet mot rättsliga och politiska aspekter av den svenska judenhetens historia, mer sällan mot judarna och samhället i en bredare bemärkelse. LÄS MER
