1. 11. Glypican-1: Structural and functional analysis of the N-glycosylated human protein

   Författare :Wael Awad Abdelhady; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteoglycans; glypicans; glypican-1; heparan sulphate; N-glycosylation; exostosin-proteins; X-ray crystallography; crystal dehydration; diffraction anisotropy; Small angle X-ray scattering SAXS9; protein spectroscopy;

   Sammanfattning : Glypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediating the signalling of various growth factors.

3. 12. Microstructural characterization of Haynes 282 after heat treatment and forging

   Författare :Ceena Joseph; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbides; gamma prime; Haynes 282; anisotropy ductility; microstructure; heat treatment;

   Sammanfattning : Over the past 75 years, solid-solution strengthened superalloys have been one among the most widely used materials for long term applications at elevated temperatures. The combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength make them an unusual class of materials, attracting researchers and scientists to explore its full potential.

5. 14. Resistive studies of vortices and fluctuations in single crystal YBa2Cu3O7-

   Författare :Therese Björnängen; KTH; []
   Nyckelord :condensed matter physics; high temperature superconductors; YB2Cu3O7-d; untwinned YBCO; oxygen deficiency; superconducting fluctuations; magnetoconductivity; in-plane anisotropy; vortex liquid; vortex solid; vortex correlation;

   Sammanfattning : High-temperature superconductors have been intensely studiedsince the discovery, almost 20 years ago. Their layeredstructure, extreme type-II behavior, large anisotropy, andstrong fluctuations have led to a large number of new andinteresting problems. LÄS MER

7. 15. Elastic and inelastic scattering effects in conductance measurements at the nanoscale : A theoretical treatise

   Författare :Peter Berggren; Jonas Fransson; Wolfgang Belzig; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scattering theory; Scanning tunneling microscopy; tunnel junctions; molecular graphene; paramagnetic molecules; spin interaction; nano electromechanical system; Josephson junction; superconductivity; chaos; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Elastic and inelastic interactions are studied in tunnel junctions of a superconducting nanoelectromechanical setup and in response to resent experimental superconducting scanning tunneling microscope findings on a paramagnetic molecule. In addition, the electron density of molecular graphene is modeled by a scattering theory approach in very good agreement with experiment. LÄS MER
