abstract this study examines the effect of teaching lexical inferencing strategies on developing reading comprehension skill of iranian advanced efl learners. participants were female students of meraj and shokouh institudes of garmsar a quasi-experimental design using two intact advanced classes of efl students at meraj and shokouh institutes. as the first step, a general toefl proficiency te...
in this study, it was aimed to determine the effects of ship dismantling zones on distribution ofheavy metal resistance and level of antibiotic resistance of bacterial isolates from eastern aegean sea coast.thirteen isolates were identified by phylogenetic analysis using 16s rdna sequences which indicated that theisolates belonged to genus bacillus. these strains were investigated in respect of...

abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
Bacterial resistances to diverse metals and antibiotics are often genetically linked, suggesting that exposure to toxic metals may select for strains resistant to antibiotics and vice versa. To test the hypothesis that resistances to metals and antibiotics are coselected for in environmental microbial assemblages, we investigated the frequency of diverse resistances in freshwater microcosms ame...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
three marine bacteria, pseudomonas putida ptcc 1664, bacillus cereus pttc 1665 and pseudomonas pseudoalkaligenes ptcc 1666 isolated from the east anzali wetland sediments of the caspian sea, were resistant to heavy metals of cadmium (cd), nickel (ni) and vanadium (v). pseudomonas pseudoalkaligenes ptcc 1666 was found to be resistant to all 3 metals ni, cd, v. heavy metal uptake was determined ...
