abstract this quasi-experimental study was aimed at examining the impact of storyline complexity on the grammatical accuracy and complexity of advanced and intermediate efl learners. a total of 65 advanced and intermediate efl learners were selected from iran language institute (ili). an intact group including 35 intermediate participants and another intact group with 30 advanced participants ...
in this study, the effects of various concentrations of nacl and kcl and partial replacement of nacl withkcl on the growth characteristics of l. monocytogenes were evaluated. it was found that l. monocytogenescan grow in the presence of 1-9% nacl and 1-11% kcl. the higher the concentration of salt used, the longerthe lag phase induced. in addition, it was observed that l. monocytogenes tolerate...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
Soluble and mitochondrial malic dehydrogenases (MDH) were isolated from root tips of the halophyte Tamarix tetragyna L. grown in the presence and absence of NaCl. The activity of the enzymes isolated from root tips grown in the presence of NaCl was lower than that of the enzymes isolated from roots grown in absence of NaCl. The mitochondrial MDH was much more sensitive to salinity than the solu...
The present study aims at designing a promising Microbial Fuel Cell (MFC) to utilize wastewater in order to generate electricity. Two types of salt bridge have been used in MFC (KCl and NaCl). The maximum electricity generation with 1M KCl and NaCl has been 823 and 713 mV, respectively. Varied salt concentrations (0.5M, 1M, 2M, and 3M) of salt bridge in MFC have been analyzed with different fac...

the effects of sodium chloride and zn rates and sources on the growth and chemical composition of lowland rice (oryza sativa l.) were studied using calcareous soil in a greenhouse experiment. the treatments comprised 5 levels of nacl (0, 12.5, 25, 37.5 and 50 mmol kg-1 soil), three zn rates (0, 5 and 10 mg kg-1 soil) and two zn sources (znso4, 2h2o and znedta). applied salinity decreased shoot ...
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...
Abstract This study utilises a recently developed, enhanced approach to assess detailed aspects of the corrosive wear behaviour different steel grades in aqueous slurries containing three NaCl concentrations (0.05%NaCl, 3.5%NaCl and 10%NaCl). Erosion-corrosion testing was conducted using slurry impingement test rig damage quantified volume loss, potentiodynamic polarisation scans surface topogr...
