a specimen of an ascomycetous fungus collected during a field trip was identified as gymnoascus baran. soil samples collected from 0-20 cm depth were studied for isolation of fungi using a soil dilution plate method. based on the morphological and molecular characters the specimens were identified as gymnoascus reesii. genomic dna was extracted and a nuclear rdna region, containing the internal...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
the present study aimed at exploring cognitions of iranian english teachers within the context of english for academic purposes (eap). to this end, the cognitions of two groups of eap teachers with respect to their pedagogical content knowledge (pck) and their sense of professional identity (pi) were probed. two language teachers and two content instructors who had at least five years of eap te...
the aim of this study was to identify the problems of translating markedness structures from english to persian in order to look closely at what possible difficulties translators may face. it also seeks to probe the strategies applied accordingly by iranian translators in translating them. from three translation of blindness novel, the sentences with marked structures were elicited and also the...
Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
conclusions: the combination of plasmid profiling and php techniques revealed the presence of diverse population of vre in sewage treatment plant in tehran. furthermore, the results showed that the php technique is a reliable method in determining the vre clonal diversity. results: all isolates were found to be resistant to erythromycin, ampicillin and ciprofloxacin. the pcr analyses showed tha...
Background and Objective: The use of lactobacilli as probiotics requires the application of accurate and reliable methods for the detection and identification of bacteria at the strain level. Repetitive sequence-based polymerase chain reaction (rep-PCR), a DNA fingerprinting technique, has been successfully used as a powerful molecular typing method to determine taxonomic and phylogenetic relat...
Oenococcus oeni is an alcohol-tolerant, acidophilic lactic acid bacterium that plays an important role in the elaboration of wine. It is often added as a starter culture to carry out malolactic conversion. Given the economic importance of this reaction, the taxonomic structure of this species has been studied in detail. In the present work, phenotypic and molecular approaches were used to ident...
Twenty P. aeruginosa isolates were collected from six cystic fibrosis (CF) patients, aged 27 to 33, in 1994 (9 isolates) and 1997 (11 isolates) at the CF Center, Copenhagen, Denmark, and were typed by pulse-field gel electrophoresis (PFGE) or ribotyping. Five of the patients had isolates with the same PFGE or ribotyping patterns in 1997 as in 1994, and ciprofloxacin had a two- to fourfold highe...
