the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
هدف این مطالعه تعیین کردن این مساله است که آیا فراگیران فارسی زبان قادر به تطبیق پارامتری ضمیر موصولی that در جملات ساده و پیچیده ی انگلیسی در سایه اصل دستور جهانی هستند یا خیر. به علاوه نقش جنسیت در رابطه با آزمون تشخیص درستی یا نادرستی جملات دستوری مورد بررسی قرار گرفت. داده ها از 54 دانشجوی فراگیر زبان انگلیسی در دانشگاه فردوسی مشهد گردآوری شد. شرکت کنندگان در آزمون شامل 28 زن (51.85 درصد)و ...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
application of therapeutic gene transfer in the treatment of genetic diseases is a notable progress but there are some disadvantages and limitations in it. the process of overcoming these barriers is a drastic change in gene delivery. recently, calcium phosphate nanoparticles alone, or in combination with viral and nonviral vectors, were found to have a positive effect on gene transfer especial...
objective: it has been suggested that low frequency stimulation (lfs) exerts its inhibitory effect on epileptogenesis through adenosine receptors activation. in the present study, effect of different lfs frequencies on a1 and a2a receptors gene expression was investigated in perforant path kindled seizures. materials and methods: animals were kindled by perforant path stimulation. afterdischarg...
abstract: advertisements are the most accessible type of authentic materials, and this is one reason why they are used more and more in english teaching classes. for this cause, studies in the field of advertisements are very widespread nowadays. for pun is one aspect which makes advertisements more interesting, it is used more than before in advertisements. use of puns makes an advertisement m...
Objective(s): This study aimed to investigate the effect of zinc oxide nanoparticles (ZnO-np) on biofilm formation and expression of the flu gene in uropathogenic Escherichia coli (UPEC) strains. Materials and Methods: Minimum inhibitory concentration (MIC) of ZnO-np was determined by agar dilution method. The effect of MIC and sub-MIC concentrations of ZnO-np on biofilm formation were determin...
Generation mean analysis (GMA) was used to study the type of gene action and inheritance of grain yield and its components. Generation mean analysis with joint scaling test was performed. This research was conducted at research farm of college of Agriculture at the University of Tehran. The parents and their progenies ( F1, F2, BC1 & BC2) in three mating groups ( Sardari × 7007, Sardari × 7107...
