monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
In a course of survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characteristics, 32 Fusarium species were i...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
abstract background: the disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6g. methods: atotal of 568 iranian soldiers went under study for isolation and identification of yeast speci...
Fifty Fusarium isolates were obtained from 20 garden soil samples in Hormozgan province (S Iran). The isolates were identified based on morphological and molecular data. Sequence data were generated for TEF-1αgene, following PCR amplification. Among the identified species, Fusariummangiferae, F.gaditjirrii, and F. decemcellularerepresent new records to the mycobiota of Iran.
Aspergillus subgenus Nidulantes accommodates species of industrial and medical importance. Thirty isolates morphologically assigned to subgenus Nidulantes were studied, 25 isolated from cereals in the north and northwestern provinces and the rest from other substrates in Iran. Based on morphological and molecular data (sequences of the ITS rDNA and β-tubulin), nine species were identified belon...
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
