This article begins by accounting the development of Second language theories .It describes major ESL theories ever since the 18th century to those currently adopted in ESL field. Then it proceeds to demonstrate their influences on EFL teaching in China, like nowadays an increasing awareness of non-cognitive factors in teaching foreign languages, reforms in some traditional teaching methodologi...

Hybrid problem-based learning (HPBL) as a learner-oriented method involves through collaboration while finding solutions to real-world problems. It has been employed in the education of English foreign language (EFL) students recently. Implementation it an EFL classroom, though might be challenging task, approved useful for improving students. The current study, using quasi-experimental design,...

To obtain insight into the role of the retinoblastoma susceptibility gene (Rb; also known as Rb1) in apoptosis, we analyzed Caenorhabditis elegans mutants lacking a functional lin-35 RB gene. We found that the loss of lin-35 function results in a decrease in constitutive germ cell apoptosis. We present evidence that lin-35 promotes germ cell apoptosis by repressing the expression of ced-9, an a...

BACKGROUND AND OBJECTIVES Dynamic hyperinflation (DH) and expiratory flow limitation (EFL) are physiologically linked and seem to be involved in the genesis of dyspnea and the quality of life (QL) impairment in chronic obstructive pulmonary disease (COPD). Advanced COPD patients often show expiratory muscles dysfunction that could be involved in DH development. AIM Study the relationships bet...

This paper examines students’ perspectives on the challenges raised by their first encounter with EMI pedagogy in higher education. The research was conducted a group of beginner students no previous experience monolingual instruction English. case studied is based two English Cultural Studies subject courses Program at Spanish university and taught learning environment total linguistic immersi...

Determining the level of expiratory flow limitation (EFL) in critical mechanically ventilated patients is of clinical relevance for choosing appropriate respiratory treatment and/or pharmacological therapy. In many respiratory diseases, EFL arises from pathological changes in the mechanical properties of the bronchial tree. These properties cannot be evaluated using common lumped-parameter mode...

This paper presents the technical aspects, theoretical analysis, and comparisons of two new permanent magnet synchronous generator (PMSG) grid-interfaced models named PMSG boost and PMSG rectifierinverter. The exact feedback linearization (EFL) control scheme is used for the effective design and stability analysis of the aforementioned models. The complexity of the EFL control laws is discussed...

Patients with severe chronic obstructive pulmonary disease (COPD) often exhale along the same flow-volume curve during quiet breathing as they do during the forced expiratory vital capacity manoeuvre, and this has been taken as an indicator of expiratory flow limitation at rest (EFL(T)). Therefore, EFL(T), namely attainment of maximal expiratory flow during tidal expiration, occurs when an incr...

The purpose of the present study is to examine a) how lower-intermediate and upperintermediate level Turkish learners of English-as-a-foreign language (EFL) realize refusals in English, b) the differences between native and non-native speakers of English in the use of refusals, and c) if L2 proficiency affects possible pragmatic transfer or not. The participants in the study included 18 native ...
