abstract english language learning in iran has become significant in recent years, and english has been included in the curriculum of iranian schools and universities, and considerable attention has been paid to this language in our society. nevertheless, teaching and learning english in iranian schools has not been able to satisfy the specified goals, so different efl institutes have been est...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...
the purpose of this study is to describe and determine the relationship between relationship marketing, customer satisfaction and intention to revisited in mashhad’s women aerobics clubs. to do this,300 randomly customers from women aerobic clubs were chosen and data was collected through kim relationship marketing questionnaire(2008) and ?=0.92, lim satisfaction questionnaire(2008) and ?=0...
production of high rapeseed yield is important in rapeseed breeding programs. with regards to the importance of estimation of general combining ability (gca), specific combining ability (sca), additive and dominance genetic variances, gene action, heterosis and heritability, an experiment was carried out in a 9×9 diallel design. nine parents with 36 crosses were studied in a randomized complete...
generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[sorghum bicolor (l.) moench. six basic generations, namely p1, p2, f1, f2,bc1p1, bc1p2 of four crosses involving seven diverse parents were evaluated inrainy 2009. the mean performance of the f1 in all the crosses indicated dominantgene effect fo...
the crown wart disease caused by urophelyctis leproides on sugar beet is very important in the growing areas of north khuzestan influencing quantity and quality of the crop. the objectives of our research were to estimate general combining ability (gca) and specific combining ability (sca) of sugar beet lines as well as the gene action governing resistance to this disease. a randomized complete...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
Improved drought-tolerant maize hybrids would significantly reduce water consumption and increase yield in arid environments. Our knowledge about genetic parameters is very essential before starting a successful breeding program. The present research was carried out throughout three successive years between 2013-15 to reveal the pattern of inheritance in yield, yield-components and related...
abstract the aim of the present study is to explore the impact of the cognitive reading strategy instruction on learners reading self-efficacy and their reading achievement. in order to fulfill this purpose, from 120 participants, 90 intermediate efl learners as an experimental group were chosen from three different educational settings namely, yazd university, yazd science and art un...
