2. 1. Simulations and experiments of turbulent diffuser flow with hydropower applications

   Author : T. Fredrik Engström; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Most hydropower plants in Sweden were built more than 50 years ago. The design tools were model tests and one-dimensional analytical methods. Since then the field of Computational Fluid Dynamics has evolved into an important engineering tool. READ MORE

4. 2. Social differences in injury risk in childhood and youth : exploring the roles of structural and triggering factors

   Author : Karin Engström; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Socioeconomic differences; health inequality; equalisation; peer victimisation; injury; children; youth; case-crossover design.;

   Abstract : Injuries are a leading cause of mortality and morbidity among children and adolescents. Injury risks are not randomly distributed across social groups. The primary aim of this thesis is to increase knowledge about the determinants of the social distribution of injuries among children and adolescents. READ MORE

5. 3. Interactions and Interference in Mesoscopic Systems: Josephson Current through Quantum Dots and Josephson Junction Arrays

   Author : Klas Engström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; quantum dots; Josephson effect; Andreev reflection; mesoscopic superconductivity; Josephson junction array; coulomb interactions; Bogoliubov-de Gennes equation; quantum phase transition;

   Abstract : The focus of the thesis is on the interplay between interactions and interference effects in mesoscopic systems. More specifically, the two main projects included deal with Coulomb interactions and Josephson effect in two superconductor-normal metal systems: (i) a Josephson junction array and (ii) a superconductor-normal metal-superconductor (SNS) system in which the normal part is a quantum dot.

7. 5. Regulation of NF-κB by Calmodulin

   Author : Åsa Antonsson; Thomas Grundström; Ylva Engström; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; NF-κB; calmodulin; transcription; calcium; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : Cells experience numerous external signals which they must respond to. Such signals arriving at the cell surface are transduced via various signal transduction pathways and often ultimately result in regulation of transcription. READ MORE
