1. 16. The drumlin problem : streamlined subglacial bedforms in southern Sweden

   Författare :Tom Dowling; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glacial flow; drumlin; self organising maps; LiDAR;

   Sammanfattning : This thesis investigates stream-lined subglacial bedforms (often referred to as drumlins) in southern Sweden. The broad aim of this is to contribute to the solution of the ‘drumlin problem’. The term drumlin has come to be applied to a wide range of features whose internal architecture (core) and overall morphology are seen to vary greatly. LÄS MER

3. 17. Glutamate modulates temporomandibular joint bone tissue resorption in patients with early rheumatoid arthritis

   Författare :Anna‐Kari Hajati; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The general aim was to investigate the occurrence and development of TMJ bone tissue resorption and to identify predictors for progression during the two first years with rheumatoid arthritis. The thesis comprises one cross‐sectional part and one longitudinal part. LÄS MER

4. 18. Aspects of the regulation of human sperm motility

   Författare :Pär K G Leijonhufvud; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : In this thesis I address some of the possible causes for oligozoospermia and low sperm motility, two factors that, singly or in combination, are often seen in cases of male subfertility. In the first study we evaluated the effect on human spermatozoa of the toxicity of compounds present in diesel exhaust. LÄS MER

5. 19. Molecular mechanisms for transcription in mammalian mitochondria

   Författare :Martina Gaspari; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :mitochondria; oxidative phosphorylation; mtDNA; transcription; TFAM; TFB1M TFB2M; POLRMT; promoter recognition; CSB II;

   Sammanfattning : The circular double stranded mitochondrial genome (mtDNA), which is about 16,600 bp in humans and 16,300 bp in mice, encodes 13 of the -90 different proteins present in the respiratory chain of mammalian mitochondria. The remaining components of the respiratory chain are encoded by nuclear genes and imported into the mitochondrial network. LÄS MER

7. 20. Antiferromagnets and Luttinger Liquids: Two Strongly Correlated Systems

   Författare :Ann Mattsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Strongly correlated systems show a variety of intriguing properties and have been extensively studied over the years. In this thesis two strongly correlated systems are discussed: the two-dimensional antiferromagnet and the Luttinger liquid. The Luttinger liquid has attracted much interest as a paradigm of non-Fermi liquid behavior. LÄS MER
