effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Effect of Abrasive Size on Wear

Evaluating abrasive wear of amorphous alloys using nanoscratch technique

The hardness and elastic modulus of several Zr, Pd, Cu, and La-based amorphous alloys were investigated using nanoindentation. Abrasive wear of these alloys was also evaluated and compared using nanoscratch techniques under a ramping load. Damage caused by scratching was examined using SEM. Material pile-up took place in all scratched samples, but to different degrees. The scratched surface was...
