Little is known about the influence of language background in problem-based learning (PBL) tutorial groups on group processes and students’ academic achievement. This study investigated the relationship between language background, secondary school score, tutorial group processes, and students’ academic achievement in PBL. A validated tutorial group effectiveness questionnaire was administered ...

The number of obese patients referred to our laboratory for pulmonary function tests is increasing: sleep breathing disorders, unexplained effort dyspnea, evaluations before surgical procedures are the main problems we are expected to cope with. In some patients with normal FEV1 and FEV1/VC values, we have observed an overlap between the tidal volume expiratory flow and the maximal forced expir...

Although persistent activation of the inspiratory muscles and narrowing of the glottic aperture during expiration have been indicated as relevant mechanisms leading to dynamic hyperinflation in acute asthma, expiratory flow limitation (EFL) has recently been proposed as a possible triggering factor for increasing endexpiratory lung volume (EELV). To establish whether the attainment of maximal f...

BACKGROUND Expiratory flow limitation (EFL) by negative expiratory pressure (NEP) testing, quantified as the expiratory flow-limited part of the flow-volume curve, may be influenced by airway obstruction of intrathoracic and extrathoracic origins. NEP application during tidal expiration immediately determines a rise in expiratory flow (V) followed by a short-lasting V drop (deltaV), reflecting ...

this study explored the relationship between efl (english as a foreign language) teachers’ emotional intelligence (ei) and their students’ motivational attributes. additionally, it investigated the contribution of efl teachers’ ei to students’ motivational factors. to these ends, 30 efl teachers were selected through convenience sampling from language institutes in najaf-abad, and were asked to...
