We determined the role of expiratory flow limitation (EFL) on the ventilatory response to heavy exercise in six trained male cyclists [maximal O2 uptake = 65 +/- 8 (range 55-74) ml. kg-1. min-1] with normal lung function. Each subject completed four progressive cycle ergometer tests to exhaustion in random order: two trials while breathing N2O2 (26% O2-balance N2), one with and one without adde...

Intracellular Ca(2+) ([Ca(2+)](i)) can trigger dual-mode regulation of the voltage gated cardiac sodium channel (Na(V)1.5). The channel components of the Ca(2+) regulatory system are the calmodulin (CaM)-binding IQ motif and the Ca(2+) sensing EF hand-like (EFL) motif in the carboxyl terminus of the channel. Mutations in either motif have been associated with arrhythmogenic changes in expressed...

pairing theory with methodology, this study demonstrates how efl teachers’ limited wait-time practice structures in and affects the structuring of the unfolding classroom discourse with reference to learners’ participation opportunities. informed by the tenets of conversation analysis, we have observed, videotaped, and transcribed line-by-line 10 efl teachers’ naturally-occurring classroom inte...

This study investigated the relationship between selfefficacy and stress among 108 EFL teachers in Iran. The participants were administered self-efficacy and stress questionnaires. Pearson Product-Moment Correlation and Multiple Regression analyses were used. The results indicated significant negative correlation between self efficacy and stress. Also it was found that both dimensions of self-e...

Poetry like other literary genres exists to be enjoyed and appreciated. The difficult task facing any instructor is to develop this sense of appreciation and enjoyment in students who are not interested in poetry. For a long time, literature in general and poetry in particular, was purged from the teaching programmes on the ground that it made no contribution to learning a foreign language for ...

INTRODUCTION During the past decade, several scholars in the fields of language education, second language acquisition, and bilingualism have addressed the influence of gender on access to linguistic and interactional resources, on dynamics of classroom interaction, and on language learning outcomes (Ehrlich, 1997; Norton, 2000; Pavlenko, 2001; Pavlenko et al., 2001; Sunderland, 2000). The fiel...

The recent emergence of digital authoring tools related to Augmented Reality (AR), such as Zooburst, Roar or Aumentaty, has facilitated the integration this cutting-edge technology in Education. Consequently, different publications have come out light about affordances and limitations integrating AR EFL/ESL classroom. Thus, study seeks analyze review trends implementation English a Foreign Lang...

The present study investigated the effect of the keyword method of vocabulary teaching on the learning and longterm retention of vocabulary in a normal EFL classroom context. Fifty elementary EFL students were selected and assigned into experimental and control groups. The experimental group received vocabulary instruction using mnemonic keyword method and the control group received conventiona...

Studies have mainly focused on strategies to motivate teachers or the student-teacher motivation relationships rather than teacher demotivation in the English as a foreign language (EFL) teaching process, whereas no data have been found on the factors that cause teacher demotivation in the Turkish EFL teaching contexts at the elementary education level. Thus, this study aims to investigate the ...
