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 ...

Data from the National LymphoCare Study (a prospective, multicentre registry that enrolled follicular lymphoma (FL) patients from 2004 to 2007) were used to determine disease characteristics, treatment patterns, outcomes and prognosis for elderly FL (eFL) patients. Of 2650 FL patients, 209 (8%) were aged >80 years; these eFL patients more commonly had grade 3 disease, less frequently received c...

Recently, speaking has played an increasingly important role in second/foreign language settings. However, in many Chinese universities, EFL students rarely communicate in English with other people effectively. The existing behavioristic role plays on New Horizon College English (NHCE) e-learning do not function successfully in supplementing EFL speaking classes. The present study aims at inves...

This study explores how Vietnamese EFL students view blogs as tools with which to practise writing, examines whether student comments assist in peer revision, and evaluates whether peer comments result in substantive revisions of written drafts. Participants in this study included 11 students in an English-as-a-Foreign-Language (EFL) classroom in Vietnam. Data collected included students’ first...

To determine whether expiratory muscle fatigue (EMF) is involved in regulating operating lung volumes during exercise, nine recreationally active subjects cycled at 90% of peak work rate to the limit of tolerance with prior induction of EMF (EMF-ex) and for a time equal to that achieved in EMF-ex without prior induction of EMF (ISO-ex). EMF was assessed by measuring changes in magnetically evok...

Abstract Norton’s (1995) Investment Hypothesis in L2 learning that L2 learners who cherish and foresee a richer personality for themselves in their L2 context would thrive more diligently and consequently would both enrich their personality and achieve a higher proficiency in their new language was investigated in this study in the community of Iranian EFL students. The integration and mutual r...

It is generally acknowledged that motivation plays a critical role in second-language (L2) reading. The technology-enhanced learning environment, specifically the computer-assisted reading environment as an interactive tool with distinctive attributes, is said to motivate English as a foreign language (EFL) learners to make more sustained efforts in online reading and show greater perseverance....

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...
