CdS-coupled TiO2 nanocrystals were prepared by the microemulsion-mediated solvothermal method at pretty low temperatures. The semiconductor nanocrystals were modified with tyrosine, phenyl alanine, glysine and glutamate aminoacids and then were characterized by BET, SEM, EDX, XRD, UV–Vis spectroscopy, and FTIR analysis methods. The specific surface area and the average pore diameter ...

this research explores the effects of three computer-mediated feedback modalities, that is, elicitation, recast, and meta-linguistics, on the learning of english participial, gerund, and infinitival phrases among iranian intermediate-level efl learners. the overriding focus of the present study was to investigate whether different types of feedback given through form-focused computer-human exch...

Purpose: The aim of present research was determine the modeling of self-regulation based on cognitive flexibility with mediated role of psychological hardiness in students. Methodology: The present study was descriptive, correlational type. The research population was all secondary high school students of Tehran city in academic years of 2019-20, which from them 499 students were selected by s...

herpetic keratitis which is resulted from herpes simplex virus type i, is considered the most common cause of corneal blindness that needs being diagnosed and treated in order to prevent irreversible eye effects. the best method to diagnose it is molecular method which has high sensitivity and exclusivity. the current study was done on 25 eye samples collected from patients referred to the feyz...

background and objectives: loop-mediated isothermal amplification is a novel nucleic acid amplification assay providing as a simple diagnostic tool for rapid identification of microbial diseases in developing countries. in this study, a lamp assay was established for yersinia enterocolitica , a leading cause of acute enterocolitis in young children. materials and methods: lamp assay was establi...

objective(s): haemostasis prevents blood loss following vascular injury. it depends on the unique concert of events involving platelets and specific blood proteins, known as coagulation factors. the clotting system requires precise regulation and coordinated reactions to maintain the integrity of the vasculature. clotting insufficiency mostly occurs due to genetically inherited coagulation fact...

this study aimed to gain an insight into whether computer-mediated communication (cmc) in the form of a digital forum can reflect gendered discursive practices. a great deal of research has now established that computer-mediated interactions embody gendered differences in the use of emoticons, but few studies have examined the potential effect of the gender of the emoticon-receiver on the frequ...

methods genomic dna of cultured s. agalactiae was prepared and loop-mediated isothermal amplification (lamp) primers were designed based on the camp gene in bacteria. the optimum primer set was selected based on the reaction speed and specificity. the reaction result was monitored visually. the sensitivity and specificity of the lamp method were evaluated and compared with polymerase chain reac...
