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...
15 صفحه اولThe Effect of Microbial Fe(iii) Reduction on Smectite Flocculation
ÐThis study was undertaken to investigate the changes in flocculation properties of Fe-rich smectite (nontronite, NAu-1) suspensions, including settling velocity, aggregate size and floc architecture associated with microbial Fe(III)-reduction in the smectite structure. The dissimilatory Fe-reducing bacterium Shewanella oneidensis MR-1 was incubated with lactate as the electron donor and struct...
متن کاملEffect of flocculation conditions on membrane permeability in coagulation–microfiltration
A coagulation–microfiltration (MF) system has the potential to remove natural organic matter and mitigate membrane fouling. The effect of flocculation conditions on MF performance was investigated using three membrane modules including stirred cell, dead-end MF, and submerged MF. The experimental results were analysed in terms of filterability, particle size, and floc structure as represented b...

15 صفحه اولFluid shear influences on flocculation Fluid shear influences on flocculation
The tube flocculator is used to study how fluid shear levels affect the settling properties of a flocculated alum-kaolin suspension. FReTA is employed to quantitatively compare the effects of varying fluid shear and hydraulic residence time on the sedimentation velocity distributions and the post-sedimentation residual turbidities of flocculated suspensions formed in the tube flocculator. Resul...
