  2. 1. Protein Dynamics Studied by NMR Spin Relaxation. Conformational Transitions of a Calmodulin Mutant

    Author : Patrik Lundström; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molekylär biofysik; Molecular biophysics; spin relaxation; rotating-frame; NMR; multiple-quantum; EF-hand; chemical shift; chemical exchange; calcium binding proteins; calmodulin;

    Abstract : Binding of calcium to the protein calmodulin leads to molecular reorganization that enables interaction with target peptides and activation of downstream processes. I have studied the dynamics of the calcium-loaded form of a C-terminal calmodulin mutant (E140Q-Tr2C) using NMR spin relaxation experiments. READ MORE

  4. 2. Development of Numerical Methods for Turbulent Flow in Complex Rotating Systems

    Author : Peter Hedberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fluid mechanics; computer code; rotating geometries; turbomachinery;

    Abstract : A computer code has been developed to predict three-dimensional incompressible turbulent flow in complex rotating geometries. The application in mind is turbomachinery in general. However such a code is able to treat a large number of problems in fluid mechanics. READ MORE

  5. 3. NMR studies of Carbohydrate Structure and Dynamics in Solution

    Author : Torgny Rundlöf; Thomas Peters; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Abstract : Methods for studies of the structures of carbohydrates in solution and their dynamics are presented. Approaches employing nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), force-field computer simulations and chemical methods are described. READ MORE

  6. 4. NMR studies on calcium-induced conformational transitions in calmodulin

    Author : Johan Evenäs; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; NMR; conformational exchange; calmodulin; calcium binding; Fysikalisk kemi;

    Abstract : Nuclear magnetic resonance (NMR) spectroscopy was used in order to investigate the relationships between structure, dynamics and calcium binding in the intracellular regulatory protein, calmodulin. Calmodulin consists of two similar domains, each binding two calcium ions with positive cooperativity. READ MORE

  7. 5. Wind turbine simulations using spectral elements

    Author : Elektra Kleusberg; Dan Henningson; Philipp Schlatter; Stefan Ivanell; Johan Meyers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind turbine; wakes; wake interaction; computational fluid dynamics; actuator line method; spectral elements; free-stream turbulence; Engineering Mechanics; Teknisk mekanik;

    Abstract : Understanding the flow around wind turbines is a highly relevant research question due to the increased interest in harvesting energy from renewable sources. This thesis approaches the topic by means of numerical simulations using the actuator line method and the incompressible Navier–Stokes equations in the spectral element code Nek5000. READ MORE
