this study was an attempt to explore the beliefs of iranian efl teachers about the role of grammar in english language teaching in both state schools and private language institutes. data were collected through a questionnaire developed by burgess and etherington (2002), which consisted of 11 main subscales and was divided into two sections. the first section dealt with approaches to grammar te...

nowadays, it is common to find optimal point of the dynamic problem; dynamic problems whose optimal point changes over time require algorithms which dynamically adapt the search space instability. in the most of them, the exploitation of some information from the past allows to quickly adapt after an environmental change (some optimal points change). this is the idea underlining the use of memo...

Despite a spate of interest in the study of the Introductions of scholarly articles, thefocal genre of knowledge construction, research is yet to reach conclusive answers onthe nature of this genre. Thus, the present study analyzed research articleIntroductions, aiming to explore how the process of knowledge construction isachieved by Iranian and international writers of English research articl...

Introduction: The neural substrates of temporal processing are not still fully known. The majority of interval timing studies have dealt with this subject in the context of “Explicit timing” (computing the time intervals explicitly). The hypothesis “Implicit timing” (implicitly using temporal processing to improve function) has also proposed. This lesion study addressed explicit and implicit ti...

based on symbolic manipulation program maple and using riccati equation mapping method several explicit exact solutions including kink, soliton-like, periodic and rational solutions are obtained for (2+1)-dimensional variable coefficient broer--kaup system in quite a straightforward manner. the known solutions of riccati equation are used to construct new solutions for variable coefficient broe...

this paper describes the theoretical and experimental investigations of the key components and also the performance analysis of a rotary wheel for using as a solid desiccant dehumidifier and also indirect evaporator cooling system. solid desiccants have long been used in dehumidification and cooling systems for energy efficiency or reduce electricity. although many mathematical models on the ro...
