abstract the current study set out to address the issue as to whether the implementation of portfolio assessment would give rise to iranian pre-intermediate efl learner autonomy. participants comprised 60 female in pre-intermediate level within the age range of 16-28.they were selected from among 90 language learners based on their scores on language proficiency test -key english test. then, t...
Using Roche/454 technology, we sequenced the chloroplast genomes of 12 Triticeae species, including bread wheat, barley and rye, as well as the diploid progenitors and relatives of bread wheat Triticum urartu, Aegilops speltoides and Ae. tauschii. Two wild tetraploid taxa, Ae. cylindrica and Ae. geniculata, were also included. Additionally, we incorporated wild Einkorn wheat Triticum boeoticum ...
Bread wheat (Triticum aestivum, AABBDD) is an allohexaploid species derived from two rounds of interspecific hybridizations. A high-quality genome sequence assembly of diploid Aegilops tauschii, the donor of the wheat D genome, will provide a useful platform to study polyploid wheat evolution. A combined approach of BAC pooling and next-generation sequencing technology was employed to sequence ...
the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...
Heat shock proteins (Hsps) are believed to play essential roles in developmental processes and in responses to heat stress. Heat shock transcription factors (Hsfs) are important Hsp regulators, but their functions are poorly understood, especially in wheat. In this study, a comprehensive bioinformatics analysis was conducted in wheat A and D genome donors, Triticum urartu and Aegilops tauschii,...
The descriptors computed by HyperChem® software were employed to represent the solubility of 40 drug molecules in supercritical carbon dioxide using an artificial neural network with the architecture of 15-4-1. The accuracy of the proposed method was evaluated by computing average of absolute error (AE) of calculated and experimental logarithm of solubilities. The AE (±SD) of data sets was 0.4 ...
هدف از تحقیق حاضر بررسی روابط بین ژنوم‌های D، S و U در سه گونه‌ی دیپلوئید از جنس گندم‌نیای وحشی (Aegilops) با ژنوم A در دو گونه‌ی دیپلوئید از جنس گندم (Triricum) با استفاده از 15 آغازگر ISSR می‌باشد. آغازگرهای ISSR توانستند 105 مکان را شناسایی کنند، که 6 مکان یک شکل و 99 مکان چندشکل بودند. میانگین تعداد مکان تولید شده 7 بود و متوسط تعداد مکان چند شکل 60/6 بود. آغازگرهای IS13، IS6 وUBC865 به عنو...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
Ab initio calculations at HF/6-31G* level of theory for geometry optimization and MP2/6-31G*//HF/6-31G*for total energy calculation are reported for Z-cyclooctene (1). The most favorable conformation of 1 is theunsymmetric boat-chair (1-BC) geometry. Potential energy profiles for two different boat-chair/boat-chairinterconversion processes were calculated. The process via a chair transition sta...
abstract this study aimed at analyzing a corpus of emails gathered from iranian students studying in england. the corpus contained 996 emails that were investigated by employing the framework of chen (2006) to find common patterns in the discourse of these emails. another aim of the study was to find how two request acts (want statements and query preparatory) were used in the emails. the...
