2. 1. Numerical and Experimental Investigation of Hydrodynamic Mechanisms in Erosive Sheet Cavitation

   Author : Mohammad Hossein Arabnejad Khanouki; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paint test; Numerical simulation; High speed visualization; Shedding behavior; Hydrodynamics mechanisms of cavitation erosion iii; Sheet cavitation;

   Abstract : Cavitation erosion is one of the limiting factors in the design of hydraulic machinery as it is associated with the reduction in the operating life-time of a hydraulic machine and a significant increase in maintenance cost. In order to be able to design a hydraulic machine with a low risk of cavitation erosion, understanding the hydrodynamic mechanisms controlling the cavitation erosion is of great importance.

4. 2. Shedding light on cognitive control

   Author : Simon Skau; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cognitive Control; fNIRS; mental fatigue; exhaustion disorder; TBI; children; mathematical cognition; proactive cognitive control;

   Abstract : This thesis aimed to investigate the ability to adjust cognitive processes and behavior, i.e., cognitive control, and its related functional activity in the cortex. READ MORE

5. 3. Analysis and control of transitional shear flows using global modes

   Author : Shervin Bagheri; Dan Henningson; Alessandro Bottaro; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; flow control; hydrodynamic stability; global modes; jet in crossflow; flat-plate boundary layer; laminar-turbulent transition; Arnoldi method; Koopman modes; balanced truncation; direct numerical simulations.; Fluid mechanics; Strömningsmekanik;

   Abstract : In this thesis direct numerical simulations are used to investigate two phenomenain shear flows: laminar-turbulent transition over a flat plate and periodicvortex shedding induced by a jet in cross flow. The emphasis is on understanding and controlling the flow dynamics using tools from dynamical systems and control theory. READ MORE

6. 4. Biophysical chemistry of the ALS-associated protein SOD1 : Implications for folding, aggregation and in-cell behaviour

   Author : Fan Yang; Mikael Oliveberg; Per Jemth; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SOD1 ALS folding in-cell NMR aggregation; Biochemistry; biokemi;

   Abstract : Biophysical chemistry deals with the structural behavior, properties and molecular function of biological macromolecules. A long-standing challenge is here to establish how these macromolecular features change upon transfer from simplified conditions in vitro to the crowded and molecularly complex environment of live cells.

7. 5. Studies on lipid transport and extracellular vesicle production in Caenorhabditis elegans ciliated neurons

   Author : Shapour Rahmani; Simon Tuck; Jonathan D. Gilthorpe; Anders Olsen; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; C. elegans; cilia; extracellular vesicles; tat; phospholipid translocase; P4-family ATPase;

   Abstract : The cilium is a protrusion of cell membrane. Both the protein and lipid contents of cilia are different from those of other parts of the cell membrane. While the transport of proteins into and out of cilia has been intensively studied, much less is known about how the lipid content of ciliary membranes is regulated. READ MORE
