The aim of this paper is to calibrate a Eulerian–Eulerian multiphase CFD model for the discharge process of an off-road self-loading concrete mixer drum, by using the viscosity model applied to fresh concrete. Two different viscosity models for the simulated concrete were studied: the Newtonian fluid model and the Bingham fluid model. The final parameters applied for calibration were defined by means...
Life in cold environments requires an overall increase in the flexibility of macromolecular and supramolecular structures to allow biological processes to take place at low temperature. Conformational flexibility supports high catalytic rates of enzymes in the cold but in several cases is also a cause of instability. The three‐dimensional structure of the psychrophilic acyl aminoacyl peptidase from...
