the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...

The rheological behaviour of ethylene glycol-based nanofluids containing hexagonal scalenohedral-shaped α-Fe2O3 (hematite) nanoparticles at 303.15 K and particle weight concentrations up to 25% has been carried out using a cone-plate Physica MCR rheometer. The tests performed show that the studied nanofluids present non-Newtonian shear-thinning behaviour. In addition, the viscosity at a given s...

The aim of this study was to use a detailed rheological characterization to gain new insights into the gelation behavior of natural waxes. To make a comprehensive case, six natural waxes (differing in the relative proportion of chemical components: hydrocarbons, fatty alcohols, fatty acids, and wax esters) were selected as organogelators to gel high-oleic sunflower oil. Flow and dynamic rheolog...

A method is described for the isolation of a structural protein of the vitreous body, which has been named vitrosin. The analyses show that vitrosin is a viscous, thixotropic, fibrous protein. Electron micrographs reveal that vitrosin particles are long fibrils, averaging 250 A in width. The isoelectric point was found to be around pH 5.5 and the shrinkage temperature 60 degrees C. Vitrosin is ...

The concept of a Deborah number is widely used in study viscoelastic materials and to represent the ratio material relaxation time timescale observation, demarcate transitions between predominantly viscous or elastic responses. However, this construct does not help quantify importance long transients non-monotonic stress jumps that are often observed more complex time-varying systems. Many thes...
