In the classical union nd problem we maintain a partition of a universe of n elements into disjoint sets subject to the operations union and nd The operation union A B C replaces sets A and B in the partition by their union given the name C The operation find x returns the name of the set containing the element x In this paper we revisit the union nd problem in a context where the underlying pa...
A facial scanner and three-dimensional computed tomography (CT) were used to evaluate the change in lip asymmetry before after two-jaw surgery for 22 patients with (menton deviation > 3 mm). We labrale superius (Ls), deviated/non-deviated-side cheilions (Ch-D/Ch-ND), inferius (Li) construct upper lower planes asymmetry. correlation analysis was performed determine factors related vertical (Δ...
In an era in which schools are expected to achieve more for their students, many teachers remain frustrated by the increasing results-driven demands made on them. A facet of teacher work life in which many feel disempowered is addressed in this study—the regular infringement of outside intrusions into the classroom learning environment. A stratified random selection of teachers in the Canadian ...
عناصر نادر خاکی (REE) در میان عناصر کمیاب کمترین انحلال دارند و بنابراین نسبت به دیگر عناصر طی فرایند هوازدگی تحرک کمتری دارند و همچنین خصوصیات REE به طور عمده وابسته به منشأ میباشد. در این تحقیق 73 نمونه سطحی در قالب رخسارههای ژئومورفولوژی تیپهای واحد دشتسر به منظور مقایسه مقادیر REE و شاخصهای REE و اندازهگیری ترکیبات اصلی و محاسبه شاخص شیمیایی تغییر از رخسارههای مختلف جمعآوری گردید. ...
Newcastle disease (ND) is one of the contagious viral diseases in avian species. Recently, several ND outbreaks in pigeon caused by pigeon paramyxovirus serotype-1 (PPMV-1) have been reported in limited numbers from Iran and phylogenetic studies have been conducted on partial sequence of NDV fusion (F) gene. In the present study, ten PPMV-1, named Pigeon_paramyxovirus1_isolate_pigeon/Iran/UT_EG...
objective(s)cardiovascular disease causes a major clinical problem in patients with end stage renal disease. since metabolic acidosis is very common in patients with end stage renal disease, we aimed to investigate the effect of experimentally-induced metabolic acidosis on serum lipid profile and aortic fatty streak (fs) formation in normal and high-cholesterol fed rabbits.materials and methods...
