construction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Concentration dependence of translational diffusion coefficients for globular proteins.
This investigation examines published results of traditional diffusion experiments on ovalbumin and bovine serum albumin to determine the extent to which assumed concentration independence of the translational diffusion coefficient is a reasonable approximation in the analysis of boundary spreading in sedimentation velocity experiments on proteins. Although significant positive concentration de...
متن کاملIntrinsic Viscosity and Friction Coefficient of Polymer Molecules in Solution: Porous Sphere Model
The intrinsic viscosity [q] and the translational friction coefficientf of polymer molecules in solution are calculated on the basis of the porous sphere model. The only information needed to predict [q] and f is the polymer molecular weight, the radius of gyration in the solvent, and the permeability as a function of position in the “porous sphere.” For systems for which this information is av...
متن کاملIntrinsic Viscosity Of
Data are presented to show that the intrinsic viscosity of hyaluronic acid elaborated into the culture medium supporting human connective-tissue cells in vitro is modulated in a systematic manner by the cells. Intrinsic viscosity is reduced during rapid cell division and by hydrocortisone treatment. Conversely, the initial lag phase of culture growth and colchicine t reatment are attended by fo...
