Whiteßies, heteropterans in the family Aleyrodidae, are globally distributed and severe agricultural pests. The mitochondrial cytochrome c oxidase I (mtCOI) sequence has been used extensively in whiteßy phylogenetic comparisons and in biotype identiÞcation of the agriculturally important Bemisia tabaci (Gennadius) whiteßy. Because of the economic importance of several whiteßygenera, and the inv...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
Eukaryotic 18S ribosomal RNA (rRNA) gene primers that feature a wide coverage are critical in detecting the composition of eukaryotic microscopic organisms in ecosystems. Here, we predicted 18S rRNA primers based on consecutive conserved sites and evaluated their coverage efficiency and scope of application to different eukaryotic groups. After evaluation, eight of them were considered as quali...
development of yeast artificial chromosome (y ac) vectors, molecular cloning of large segments of chromosomal dna, and their propagation in yeast cells has become feasible. overlapping y ac provides a route to the development of physical maps of entire mammalian chromosomes. a rapid method was developed to isolate and sequence termini of y ac inserts quickly. the y ac clone is digested with a r...
towelve calves of 4-10 months old with clinical signs suspected to bovine viral diarrhea virus (bvdv) infection were selected for this study. histopathologic sections were performed on formalin fixed paraffin-embded ear notch biopsies, mounted on poly-l-lysine coated slides and stained for bvdv by anti-bvdv monoclonal antibody labelled with fluorescein isothiocyanate. stained sections were exam...
Background: Beta- lactamase enzymes are the most important resistant factors to beta lactam antibiotics among gram negative bacteria. Nowadays, the prevalence of beta- lactamase infection is increasing worldwide and drawn the scientists attention as an important subject. Due to high prevalence of bacteria contained TEM beta lactamase and AmpC enzymes, using molecular methods especially designin...
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...
