    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oblique compression.; C -type shear bands; anastomozing shear zones; tubular folds; lineation-parallel folds; northern Sweden; Grapesvare Nappe; Seve Nappe Complex; Finnmarkian; Eclogite; corona dolerite; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Sammanfattning : In the Seve Nappe Complex of the Swedish Caledonides, coronitic diabases pass into eclogites; sometimes the transition occurs within one and the same boudin. Calculated pressure-temperature conditions for the eclogite facies stage are 20-27 kbar and 650-750°. LÄS MER

  3. 2. Structural and functional studies of proteins of medical relevance : Protein-ligand complexes in cancer and novel structural folds in bacteria

    Författare :Robert Gustafsson; Pål Stenmark; Pavlína Řezáčová; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray crystallography; Cancer; MTH1; oxidised nucleotides; MTHFD2; nucleotide metabolism; one-carbon metabolism; Botulism; Botulinum neurotoxin; OrfX; OrfX gene cluster; Biochemistry; biokemi;

    Sammanfattning : X-ray crystallography is a tool for determining the structures of proteins and protein-ligand complexes. In this thesis the method has been employed to study several proteins of medical relevance.Cancer is a terrible disease, severely impacting those affected, as well as their family and friends.

  4. 3. Lipid Nanotubes as a Model for Highly Curved Cellular Membrane Structures

    Författare :Natalia Stepanyants; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cells and their organelles show a variety of membrane morphologies with multiplesubmicrometer features, for example, tubules, vesicles, folds and pores. The shape of thecellular membranes can dynamically change to support a variety of functions, such as cargotransport, transmission of signals between the cells, cell movement and division. LÄS MER
