this study investigated the effect of oral dialogue journals on communicative competence of iranian efl learners. participants of this study were 80 students of two payam-e-noor universities who were proved to be homogenous in the communicative competence based on tse (test of spoken english) interview. the participants of one of these universities were considered as the experimental group. the...

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...

abstractthe current study examined the modification devices (mds) used by non-native speakers (nnss) learning efl during dyadic task-based interactions. three meaning-oriented tasks, namely picture-description, spot-the-difference, and opinion-exchange, were used to elicit data from 24(12 male and 12 female, forming 4 male-male, 4 female-female, and 4 male-female dyads) iranian efl learners wit...

Near-synonyms are words which share certain semantic similarities, yet differ in their contextual usage (e.g. acquire vs obtain, evaluate judge). The current study compares lexical preferences and rationalizations for choosing near-synonyms of advanced C1 level non-native speakers English (n = 45) to those given by native 58). data has been collected using a forced-choice questionnaire also inc...

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...

An algorithm for labeling a two-speaker phone call according to the active speaker at each time frame is presented. The algorithm is based on clustering audio frames according to one features set, and then modeling speakers for each cluster and resegmenting iteratively, over a different features set. The first clustering stage is expected to yield clusters that contain audio of both speakers gr...

research on multiword clusters (chunks) is based on the assumption that native speakers use plenty of chunks in their everyday language and they are considered as fluent speakers of language. therefore the present study was an attempt to investigate the impact of using chunks on speaking fluency of iranian efl learners. in the first phase of the study, the students of two intermediate classes s...
