sno nanoparticles were synthesized using microwave–assisted hydrothermal method. it was noticed that at 300 and 600 watt microwave power, sno formed and remained in the tetragonal phase. at 900 watt, sno2 started appearing and a mixture of sno and sno2 phases coexisted. the particle size varied from ~2 to ~13 nm at 300 to 900 watt radiation power. the uv-v absorption spectra showed the excitoni...

in this study two modes ofreading (car and traditional print mode) were compared in regards to their effectiveness for l2 reading comprehension. a group of 120 english major students were divided into three classes: car, traditional, and control. based on the english proficiency scores each class was divided into two groups (high and low levels of proficiency). three classes were taught by the ...

background: in recent years, the high likelihood of the implantation of transferred embryos has led to an increase in the number of multiple pregnancies and consequently an increased risk of complications in fetuses and mothers. since the aim of infertility treatment is the birth of a healthy child while preserving the mother’s health, therefore, attempts should be made to avoid multiple pregna...

background: more and more infertile patients have accepted the assisted reproductive technique (art) therapy. concerns have been raised over an increased risk of adverse maternal outcomes in art populations as compared with natural conception (nc). objective: the aim was to improve the art in clinicial work and to reduce the incidence of pregnancy complications in art group according to analyzi...

background:   objective: this study aimed at investigating the side effects and hemodynamic effects of using thiopental sodium and propofal as well as effects of these drugs on pregnancy outcome in art cycles.   materials and methods: in this double blinded) randomized controlled trial, 90 woman candidate for art were randomly divided into two groups. 47 patients received propofol (2.5 mg/kg) a...

This study explored the effectiveness of the two computer-assisted modes: cooperative and individual on improving Iranian high school students’ reading comprehension. It was also concerned with investigating the effectiveness of the two computer-assisted modes on the participants’ foreign language learning anxiety (FLLA).
