Theme-Rheme theory is one of the important components in text linguistics, which is closely related to language teaching and learning. This paper applies the Theme-Rheme theory in EFL reading teaching for nonEnglish majors in college, and explores its influence on students’ EFL reading proficiency. The result of this study proves that the Theme-Rheme theory is an effective system and it has cer...

BACKGROUND The eukaryotic elongation factor EF-1alpha (also known as EF1A) catalyzes aminoacyl-tRNA binding by the ribosome during translation. Homologs of this essential protein occur in all domains of life, and it was previously thought to be ubiquitous in eukaryotes. Recently, however, a number of eukaryotes were found to lack EF-1alpha and instead encode a related protein called EFL (for EF...

Translation elongation factor 1alpha (EF-1alpha, or EF-Tu in bacteria) is a highly conserved core component of the translation machinery that is shared by all cellular life. It is part of a large superfamily of GTPases that are involved in translation initiation, elongation, and termination, as well as several other cellular functions. Eukaryotic EF-1alpha (eEF-1alpha) is well studied and widel...

We have previously observed large phasic variations of respiratory mechanical impedance in chronic obstructive pulmonary disease (COPD) patients mechanically-ventilated for acute respiratory failure, and postulated that they were due to expiratory flow limitation (EFL). The aim of this study was to test that assumption experimentally and to assess the value of impedance for automatic and noninv...

This article reviews Vygotsky’s sociocultural theory as one of the current frameworks in the study of learning and teaching processes. Arguing that learners’ interaction is vital for language learning in English as a Foreign Language (EFL) classrooms and that the teacher’s perceptions and expectations can foster or discourage this interaction, the article shows how the sociocultural model of le...

Expiratory flow limitation (EFL) can occur in mechanically ventilated patients with chronic obstructive pulmonary disease and other disorders. It leads to dynamic hyperinflation with ensuing deleterious consequences. Detecting EFL is thus clinically relevant. Easily applicable methods however lack this detection being routinely made in intensive care. Using a simple mathematical model, we propo...
