1. 11. A Study of the Initial Mould Filling during Up-hill Ingot Casting

   Författare :Line Hallgren; Pär Jönsson; Anders Tilliander; Seppo Louhenkilpi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; up-hill teeming; nozzle; casting; fluid flow; modelling; CFD; LDA; swirl; ingot casting; filling; red eye;

   Sammanfattning : The fluid flow in the mould during up-hill teeming is of great importance for the quality of the cast ingot and thereby the quality of the final steel products. At the early stage of the filling of an up-hill teeming mould, liquid steel flows with a high velocity from the runner into the mould. LÄS MER

3. 12. Models of the metabolism of the pancreatic beta-cell

   Författare :Pål Westermark; Anders Lansner; Jean-Pierre Mazat; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Computer science; Datalogi;

   Sammanfattning : The pancreatic β-cell secretes insulin in response to a raised blood glucose level. Deficiencies in this control system are an important part of the etiology of diabetes. LÄS MER

4. 13. Modelling of muscular force induced by non-isometric contraction

   Författare :Natalia Kosterina; Anders Eriksson; Michael Günther; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Skeletal muscle; Muscular force; Concentric contractions; Eccentric con- tractions; History effect; Force modification; Muscle model; Musculoskeletal model;

   Sammanfattning : The main objective of the study was to investigate and simulate skeletal muscleforce production during and after isometric contractions, active muscle lengtheningand active muscle shortening. The motivation behind this work was to improve thedominant model of muscle force generation based on the theories of Hill from 1938. LÄS MER

5. 14. Molecular Evolution of the Vertebrate Genome

   Författare :Kiwoong Nam; Hans Ellegren; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In this thesis, I studied molecular evolution of the vertebrate genome, focusing on sex chromosomes, protein coding genes, and genome size variation. The evolutionary history of avian sex chromosomes was analyzed by comparing substitution rate among 12 gametologous gene pairs on the Z and W chromosomes. LÄS MER

7. 15. Quantifying Phagocytosis – studies on the antibody response during invasive streptococcal infections

   Författare :Therese de Neergaard; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phagocytosis; Hill equation; Streptococcus pyogenes GAS ; Streptococcus dysgalactiae; Antibodies; invasive infection; Phagocytosis; Hill equation; Streptococcus pyogenes; Group A Streptococcus; Streptococcus dysgalactiae; Antibodies; Invasive infection;

   Sammanfattning : The interaction between our immune system and pathogens encompasses a complex spectrum from symbiosis to potentially life-threatening diseases. Throughout evolution, our immune system has evolved numerous strategies such as phagocytosis to combat infections and protect us from diseases. LÄS MER
