The present study is an attempt to compare the use of different forms of greeting speech acts presented in Iranian junior high school textbooks, i.e. Prospect series (I, II, III) and Four Corners series (1, 2, 3 and 4) which are quite popular in Iranian high schools and institutions. To this end, greeting forms in the language function and conversation sections of these two series were analyzed...

The parametric resonance of the axial vibrations of a cantilever pipe conveying harmonically perturbed two-phase flow is investigated using the method of multiple scale perturbation. The nonlinear coupled and uncoupled planar dynamics of the pipe are examined for a scenario when the axial vibration is parametrically excited by the pulsating frequencies of the two phases conveyed by the pipe. Aw...

This study was an analytical account of EFL postgraduate learners’ use of verbs in citing other scholars in their own writing. Particular interest was differing extents of these verbs as categorised by Myer (1997), namely verbs representing statement of scholarly writing, verbs communicating knowledge of scholarly writing, and verbs denoting cognition of scholarly writing, each of which has sub...

[1] This study analyzes the effects of thermocline shoaling on the ocean internal wave (IW) generation in the north South China Sea (NSCS). Seven years of satellite synthetic aperture radar (SAR) images from 1995 to 2001 are used for the statistical analysis of IW occurrence, and field measurements of sea surface wind, sea state, and vertical temperature profiles are used for analyzing IW gener...

Cytogenetic studies were performed on 150 cases of Down's syndrome (DS) in Iran. The standard trisomy 21 was found in 132 (88 % ) and translocation-trisomy 21 (+21) in 18 (12%) patients, i.e., t(21,21) in 1(0.63%) and mosaicism in 17(11.33%) cases. The comparison of the frequencies for mosaicism between different populations such as Denmark, Hungary, Egypt, Iraq, India, Australia and Iran ...

This study investigated nine General English books (five produced by non-native Iranian speakers and four produced by native speakers) in terms of learning objectives in Bloom’s Revised Taxonomy (2001). The aim was to find out which levels of Bloom’s Revised Taxonomy are dominant in the books. So, the contents of the books were codified based on a coding scheme designed by Razmjoo and Kazempurf...

In this paper, optimization of the sound transmission loss of finite rectangular anisotropic laminated composite plate with simply supported boundary conditions has been developed to maximize transmission loss. Appropriate constraints were imposed to prevent the occurrence of softening effect due to optimization. For this purpose, optimization process was incorporated into comprehensive finite ...

Top-down contextual influences play a major part in speech understanding, especially in hearing-impaired patients with deteriorated auditory input. Those influences are most obvious in difficult listening situations, such as listening to sentences in noise but can also be observed at the word level under more favorable conditions, as in one of the most commonly used tasks in audiology, i.e., re...
