2. 1. Blood flow specific assessment of ventricular function : Visualization and quantification using 4D flow CMR

   Author : Alexandru Grigorescu Fredriksson; Carljohan Carlhäll; Bengt Johansson; Linköpings universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The spectrum of cardiovascular diseases is the leading cause of morbidity and mortality globally. Early assessment and treatment of these conditions, acquired as well as congenital, is therefore of paramount importance. The human heart has a great ability to adapt to various hemodynamic conditions by cardiac remodeling.

4. 2. Rock grouting design: Rheological aspects and radial flow visualizations with ultrasound

   Author : John Shamu; Stefan Larsson; Ulf Håkansson; Liangchao Zou; Chadi El Mohtar; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement grouts; grouting; yield stress fluid YSF ; thixotropy; critical shear rate; radial flow; wall slip; Bingham model; Cementbaserade injekteringsmedels; injektering; icke-Newtonska vätskors; tixotropi; kritisk deformationshastigheten; radiella strömning; glidning; Bingham modell; Jord- och bergmekanik; Soil and Rock Mechanics;

   Abstract : The rheological properties of cement-based grouts play a crucial role indetermining the final spread in grouted rock formations. In rheological terms,cement grouts are known to be complex time-dependent yield stress fluids,but their steady flow behavior is often described by the simple Binghamconstitutive law. READ MORE

6. 4. Visual thinking, visual speech : a semiotic perspective on meaning-making in molecular life science : how visualizations, metaphors and help-words contribute to the formation of knowledge about proteins among upper secondary and tertiary level students

   Author : Carl-Johan Rundgren; Lena A E Tibell; Richard Hirsch; Ute Harms; Linköpings universitet; []
   Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Molecular life science; visualizations; metaphors; help-words; Subject didactics; Ämnesdidaktik;

   Abstract : Molecular life science has become one of the fastest-growing fields of scientific and technical innovation. An important issue for tomorrow’s education is to meet the challenge posed by various facets of molecular life science. READ MORE

7. 5. Prediction of Cooling Air Flow in Electric Generators

   Author : Pirooz Moradnia; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Multiple Reference Frame; PIV; Total Pressure Measurements; Electric Generator; Experimental Measurements; 5-hole Pressure Probe Measurements; Flow Prediction; OpenFOAM;

   Abstract : The cooling air flow in hydro power electric generators is investigated experimentally and numerically. A fully predictive numerical approach is presented and validated, in which the inlet and outlet boundaries are eliminated from the computational domain. READ MORE
