a growing body of research has indicated that students of esl/efl are reticent and unwilling to be engaged in oral activities in english lessons. communicative language ability includes speaking ability, so vocabulary knowledge plays an integral role in speaking a language. however, there have been few studies examining the degree to which vocabulary knowledge affects speaking ability. the pres...

NBDB database describes protein motifs, elementary functional loops (EFLs) that are involved in binding of nucleotide-containing ligands and other biologically relevant cofactors/coenzymes, including ATP, AMP, ATP, GMP, GDP, GTP, CTP, PAP, PPS, FMN, FAD(H), NAD(H), NADP, cAMP, cGMP, c-di-AMP and c-di-GMP, ThPP, THD, F-420, ACO, CoA, PLP and SAM.

So far, knowledge convergence has been a widely neglected aspect of collaborative knowledge construction. Collaborative learners contribute their individual knowledge resources, discuss the contributions of their learning partners, and eventually synthesize their individual perspectives. In collaborative knowledge construction groups of learners may be characterized by convergence or divergence...

BACKGROUND The results of an in vivo study on the "ratio method" used in electronic foramen locators (EFL) are presented. EFLs are becoming widely used in the determination of the working length (WL) during the root canal treatment. The WL is the distance from a coronal reference point to the point at which canal preparation and filling should terminate. The "ratio method" was assessed by many ...

The breadth and depth of ESL learners’ vocabulary knowledge and their comprehensive linguistic competence are not well studied in current literatures on vocabulary studies. This paper explores the creditability of depth and breadth of ESL learners’ vocabulary knowledge as an indicator of their overall linguistic competence and the correlation between depth and breadth of ESL learners’ vocabular...

The current study is an attempt to investigate the particular role learners' vocabulary knowledge plays in their reading comprehension performance. It intends to determine whether breadth and depth of vocabulary knowledge are related to EFL learners' reading comprehension, and to investigate which one of these variables, that is, depth or breadth of vocabulary knowledge, makes a more important ...
