This paper describes an improved model for multiple building diffraction modeling based on the uniform theory of diffraction (UTD). A well-known problem in conventional uniform theory of diffraction (CUTD) is multiple-edge transition zone diffraction. Here, higher order diffracted fields are used in order to improve the result; hence, we use higher order diffraction coefficients to improve a hy...

Background: Multiple pregnancies are responsible for the increased risk of maternal and neonatal morbidity and mortality. This study aimed to compare the perinatal outcome between multiple and singleton pregnancies. Materials and Methods: This is a retrospective cohort study. A sample of 50 multiple birth neonates- born in Fatemieh Hospital of Hamadan, Iran in 2015- was selected using simple r...

One of the issues of youth in Iranian society and Tehran city is drug use. Drug use is influenced by various factors (environmental and individual). In Bandura's cognitive-social learning theory, the process of integrating the individual and social factors on each other has been emphasized. Therefore, this research is shaped by this theory. The purpose of this article is to develop a model of d...

multiple intelligences (mi), second/foreign (l2) proficiency and gender are postulated to contribute to language learning strategies (lls). this study, first, examined whether there was any relationship between iranian efl learners’ lls, on the one hand, and their mi, l2 proficiency, on the other hand. in so doing, it explored the relationship of the overall l2 strategy as well as individual st...
