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 acid proteinase inhibitors on chicken pepsin.
1. The activity of chicken pepsin was partially inhibited by dimethyl-(2-hydroxy-5-nitrobenzyl)sulphonium bromide, but was unaffected by p-bromophenacyl bromide. 2. In the presence of Cu2+, diazoacetylnorleucine methyl ester completely inactivated chicken pepsin with the incorporation of 1 mol/mol. The mechanism of the reaction was similar to that with pig pepsin. 3. Chicken pepsin was complete...
متن کاملThe effect of guanidine hydrochloride on crystalline pepsin.
In a previous communication, it was shown that on prolonged exposure to urea at temperatures above 20” pepsin is irreversibly inactivated (1). The loss of activity is most marked in the pH range of 4.6 to 5.6 and is always accompanied by the formation of nonprotein material that originates from autodigestion of the protein. Since urea is known to affect the secondary structure of proteins by ru...
متن کاملThe effect of high pressures on pepsin and chymotrypsinogen.
A study of the inactivation of trypsin and chymotrypsin by high pressures was reported previously (1). The effects of high pressure on pepsin and chymotrypsinogen, and on the activation of chymotrypsinogen by trypsin, have now been examined. The effect of high pressure on crystalline pepsin was investigated by Matthews, Dow, and Anderson (2), in particular as affected by magnitude of pressure a...
متن کاملThe Effect of “Healing with Intent” on Pepsin Enzyme Activity
This study was conducted in an attempt to determine whether “healing with intent” could be shown to exert an effect on pepsin enzyme activity which, if proven, might serve to raise the credibility of healing as a bona fide therapy. The ability of healing to influence enzyme activity was chosen as a method of assessment as it eliminated the possibility of the placebo effect, which is often encou...
