چکیده هدف اصلی این پژوهش تعیین رابطه استراتژیهای خود رهبری و خلاقیت اعضای هیات علمی دانشگاه علم و صنعت بوده است. در این پژوهش از روش توصیفی از نوع همبستگی استفاده شده است. جامعه آماری پژوهش کلیه اعضای هیات علمی دانشگاه علم و صنعت در سال تحصیلی 88-1387 بود که بالغ بر345 نفربودندو از این تعداد، 119 نفر استاد با استفاده از روش نمونه گیری تصادفی طبقه ای متناسب با حجم انتخاب شد. ابزار جمع آوری داده...
The bovine leptin (LEP) gene was widely used as a candidate gene for molecular selection to improve productivity traits of cattle. This study was carried out to identify single nucleotide polymorphisms (SNPs) in the LEP gene of Sumba Ongole (SO, Bos indicus) cows using sequencing method. A total of 31 animals were used in this study for analyses. Research showed that total of 16 SNPs w...
abstract this study aimed at investigating the effect of bilingual teaching of cognate words (persian-english) on iranian upper intermediate efl learners’ knowledge of lexical development. for this purpose,100 subjects participated in this study out of which 40 learners were selected for this study and they were assigned into two groups, control and experimental. cross-language cognates (wor...
foroughmand et al. (1) have recently reported association between coronary artery disease (cad) and two well-known single nucleotide polymorphisms (snps) on chromosome 9p21.3 in subjects from south-west iran. we doubt the validity of their findings. genotyping was done using arms-pcr for rs1333049 and rs10757274 in their study. when we first looked at the genotype frequencies, we observed a sub...
objective: neuregulin1 (nrg1) gene is among the most promising candidate genes for schizophrenia. this gene is located on 8p22-p12, a region with a reported linkage to schizophrenia. several studies have reported an association between schizophrenia and the 5′ end polymorphisms in this gene. however, some studies have failed to confirm the role of nrg1 gene in the pathogenesis of schizophrenia....
هدف تحقیق حاضر بررسی تاثیر نشانه های فرا گفتمان متنی بر فهم متون انگلیسی به وسیله ی زبان اموزان فارسی زبان است.این تحقیق علاوه بر این کوشیده است تا میزان اگاهی این زبان اموزان و نحوه ی تعامل انان را با متون خوانده شده در زبان انگلیسی به وسیله ی پرسش نامه ی تهیه شده بررسی کند.بر اساس محتوای یک متن انگلیسی یازده سوال درست /غلط طرح گردید و یک مرتبه با ان متن و یک مرتبه با نسخه ای که نشانه ها...
specific trait candidate genes are sequenced genes with known biological activity. the effects of pou1f1 and stat5a on milk production traits have been studied in several studies. pou1f1 affects on transcription of prolactin and growth hormone gene, as well as, stat5a is known as a main mediator of growth hormone action on target genes and intracellular mediator of prolactin signaling. since th...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
در این تحقیق، تنوع ژنتیکی جمعیت آرتمیا اورمیانا و آرتمیا فرانسیسکانا ی موجود در ایران با استفاده از 5 جفت آغازگر ریزماهواره ای (af-b105tail، af-a136، apdq03tail، apdq04tail و apdq05tail) ویژه ی آرتمیا فرانسیسکانا و آرتمیا پارتنوژنتیکا بررسی شد. از 50 سیست آرتمیا ی هر یک از این دو جمعیت به صورت انفرادی dna با روش گلوله ی داغ استخراج شد. با استفاده از آغازگر ها ی پنج گانه و از طریق واکنش زنجیره ا...
ccl22 16c/a genetic variation is not associated with breast carcinoma in southern iranian population
background: ccl22/mdc is a cc chemokine with a critical role in regulation of the immune balance in physiological condition. ccl22/ccr-4 ligation has been documented to participate in the migration of regulatory t (treg) cells and th2 lymphocytes to the site of breast tumors; circumstances that are known to be associated with poor prognosis. objective: to investigate the association of a single...
