Heart Enlarging Effect of Phenyl Glyoxal

Complexes of Some Platinum Metals with /»-Diethylamino Anil of Phenyl Glyoxal

Complex compounds of platinum metals Ru(III), Rh(III), Os(IV), Ir(IlI) and Pt(IV) with the bidentate Schiff base ligand derived by the condensation of phenyl glyoxal with p-diethylamino aniline have been prepared and characterized. All the complexes are stable at room temperature. The complexes of Ru(III) and Os(IV) are Paramagnetic and the other complexes of Rh(III), Ir(III) and Pt(IV) are dia...

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...

Enlarging Learnable Classes

An early result in inductive inference shows that the class of Ex-learnable sets is not closed under unions. In this paper we are interested in the following question: For what classes of functions is the union with an arbitrary Ex-learnable class again Ex-learnable, either effectively (in an index for a learner of an Ex-learnable class) or noneffectively? We show that the effective case and th...
