the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولSyntheses of Substituted 1,3,4-Oxadiazole, 1,3,4-Thiadiazole and 1,2,4-Triazole Derivatives as Potential Antimicrobial Agents
A series of 2-(4-nitro-1-imidazolylmethyl)-1,3,4-oxadiazole, 1,3,4-triazole and 3-(4-nitro-1-imidazolylmethyl)-1,2,4-triazole derivatives were synthesized and tested for their antimicrobial activity. Some of the tested compounds were active against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Clostridium difficile, Aspergillus niger and Cryptococcus neoformans.

متن کاملSynthesis and biological evaluation of 1,2,4-triazole and 1,3,4-thiadiazole derivatives as potential cytotoxic agents.
A series of new 3-amino-5-sulfanyl-1,2,4-triazole and 2-amino-5-sulfanyl-1,3,4-thiadiazole derivatives have been synthesized and their cytotoxicities were evaluated on a panel of human cancer cell lines (BxPC-3, H1975, SKOV-3, A875, HCT116, etc.). The best one (compound 5m) exhibited activities with IC50 values ranging from 0.04 to 23.6 µM against nine human cancer cell lines. Further biologica...
