molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. by this method we can calculate many chemical and biochemical properties of large scale biological systems. in this work all-atom molecular dynamics simulation of polyalanine (pa) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 m of guanidinium chlorid...

the present study investigated efl teachers’ beliefs about oral corrective feedback (cf), their cf-provision practices across elementary and intermediate levels, and their beliefs-practices correspondence. to this end, the researchers conducted a semi-structured interview with the teachers and went on an overall forty-hour observation of their classrooms across both levels. the findings reveale...

Its purpose is to provide an impartial meeting ground for carriers, shippers, government officials, consultants, university researchers, suppliers, and others seeking exchange of information and ideas related to both passenger...

The paper describes a research project which conducted participatory design in a non-profit organisation based on the work of volunteers. The project is analysed by identifying contradictions in the course of the project, and then fitting these contradictions into the activity theory based, developmental work research framework. It is concluded that the perspectives of contradiction and activit...
