abstract: the present study is about prophet ishmael, some parts of his life; his personality in the quran and the bible; and the comparison of the content of these two religious books. compilation of the study has been done with a new perspective and new presentation approach. since prophets have been human beings’ role model and their life has been a perfect example for humanity in all ages,...
background: the increase in the prevalence of cesarean section (c-section) in recent decades has become a public health problem worldwide. studies of cesarean section in order to identify the causes and form policies and interventions to reduce the incidence of this health problem are necessary. this study was conducted with the aim to investigate the causes of c-sections performed at niknafs a...
the purpose of this study is to survey cross section changes of the animal brain samples during the tension and compression tests and comparison of the experimental results for three animals: bovine, sheep, and rabbit. a linear elastic theory with considering the necking in tension and barreling in compression has been considered for brain tissue. bridgman method for tension and cross section u...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
Background and purpose: Increase in cesarean section (C-Section) is a health system problem around the world. The aim of this study was to compare the rate of C-Section and indications for that before and after implementation of Health System Reform in the hospitals of Mazandaran province, Iran. Materials and methods: This descriptive cross-sectional study was conducted analytically. The indic...
nowadays enhancing critical thinking in learners is considered one of the foreign language teachers’ tasks due to its high position in foreign language classrooms. when it comes to selecting materials for language classrooms, there are obviously some criteria that teachers should apply. the present study aimed at a critical thinking based analysis of ten picture story books and ten folktales th...
In the present study, free vibration behaviors of of carbon nanotube (CNT) and boron nitride nanotube (BNNT) have been investigated via Eringen’s nonlocal continuum theory. Size effect has been considered via nonlocal continuum theory. Nanotubes have become popular in the world of science thanks to their characteristic properties. In this study, free vibrations of Boron Nitride Nanotube (BNNT) ...
The problem of solving open 2D scattering problems using the finite element method (FEM) and the multi-filament current method (MFCM) is addressed in this paper. The second order absorbing boundary condition of Bayliss-Turkel, for noncircular boundaries, and the filament positioning problem in MFCM are investigated. Two problems defined by two perfect cylindric dielectric bodies, with circular ...
