2. 1. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

   Author : Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

   Abstract : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. READ MORE

4. 2. A Structural Viewpoint of Magnetism in Fe and Co Based Superlattices

   Author : Matts Björck; Gabriella Andersson; Adrian Rennie; Thomas Hase; Uppsala universitet; []
   Keywords : Physics; Magnetism; Multilayer; Superlattice; X-ray magnetic circular dichroism; X-ray diffraction; X-ray reflectivity; Neutron diffraction; Structural refinement; Interfaces; Fysik;

   Abstract : In order to understand the properties of thin film devices, knowledge of the material's structure is essential. The work presented here combines magnetic and structural characterization of the systems studied to gain a deeper physical understanding. READ MORE

5. 3. The Design and Structure Prediction of Protein Oligomers

   Author : Robert Lizatovic; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virus capsids; coiled coils; molecular replacement; symmetry; Rosetta; protein design; structure prediction;

   Abstract : The minimum free energy state of a protein (the native state) is encoded by its amino-acid sequence. Due to the many torsional degrees of freedom (DOF) available to a polypeptide chain, a vast number of conformations is possible. READ MORE

6. 4. Complex Phase Behavior in Thermoelectric Mg2Si1-xSnx Alloys and Development of Transient Plane Source Method for Structural Characterization

   Author : Andrey Sizov; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiphase structure; quality control; inhomogeneity tests; Rietveld refinement; Transient Plane Source method; isotropic and anisotropic materials; defects detection; advance measurements of thermal properties; X-ray diffraction; structural characterization; spark plasma sintering; magnesium silicide-stannide alloys; complex behavior; thermoelectric properties; thermal conductivity vs. probing depth;

   Abstract : The thermoelectric effect was discovered nearly 200 years ago, but it started to be utilized for waste heat recovery only fairly recently. From an economical point of view, such applications requires a cheap and efficient material, which is able to convert heat energy into electricity. READ MORE
