the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...
the most common pathogenic agent in sunflower is sclerotinia sclerotiorum which in some cases can be successfully controlled by some antagonistic bacteria. environmental factors such as carbon sources are effective on antagonistic strains but application of pure carbohydrates for mass production of these agents is expensive. so in most cases agricultural and industrial residues (such as molasse...
A modification of the Adler capillary assay was used to evaluate the chemotactic responses of several denitrifiers to nitrate and nitrite. Strong positive chemotaxis was observed to NO(3) and NO(2) by soil isolates of Pseudomonas aeruginosa, Pseudomonas fluorescens, and Pseudomonas stutzeri, with the peak response occurring at 10 M for both attractants. In addition, a strong chemoattraction to ...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
cohesion is an indispensable linguistic feature in discourse analysis. lexicald such a differe cohesion and conjunction in particular as two crucial elements to textual cohesion and comprehension has been the focus of a wide range of studies up to now. yet the relationship between the open register and cohesive devices has not been thoroughly investigated in discourse studies. this study concen...
The effect of temperature on the growth kinetics and proteolytic activity of Chryseobacterium joostei and Chryseobacterium bovis was determined during this study. The results were compared with the activities of Pseudomonas fluorescens, which is regarded to be a major food spoilage psychrotolerant microorganism. For the growth studies, cultures were incubated in nutrient broth in a temperature ...
building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
the chitinase producing ability of pseudomonas fluorescens strains viz., pf1, pb2 and fp7 was evaluated in a culture medium with and without a chitin source. the addition of 1% (v/v) chitin in culture medium significantly increased the bacterial population and chitinase activity. among three strains tested, fp7 responded well to the addition of chitin by producing 31.2% increased chitinase in c...
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
Eleven endophytic bacteria were isolated from the roots of cumin, a medicinal plant grown in Assiut Province, Egypt. The strains KAU2025 and KAU2022 exhibited highest inhibition rate against Fusarium oxysporum (FOC7) (64%) dual culture test selected for further studies. identified as Brevibacillus parabrevis Pseudomonas fluorescens, respectively, based on 16S rDNA sequence analysis. isolates in...
