a 7.5 year-old girl was seeking orthodontic treatment because of severe ectopic eruption of maxillary first permanent molars. it was a rare case that represented approximately horizontal view in panoramic radiograph. the severity of problem was high, but since the patient had maxillary deficiency, it was important to perform the treatment without extraction. treatment began with extraction of u...
we conducted this study to compare fecal calprotectin between exclusively breastfed and formula or mixed fed infants aged one month and six months. sixty term infants were enrolled from the labor ward of valiasr hospital between oct 2011 and july 2015 and their fecal calprotectin was checked by the elisa method and hycult biotech kits. the enrolled infants had a birth weight of 2500-4000 g and ...
background:growth is one of the most important indices in child health. the best and most effective way to investigate child health is measuring the physical growth indices such as weight, height and head circumference. among these measures, weight growth is the simplest and the most effective way to determine child growth status. weight trend at a given age is the result of cumulative growth e...

background: unrestricted somatic stem cells (ussc) are cord blood stem cells that have been considered as candidates for the regulation of immune responses. therefore, potential exists for their use in the suppression of immune response after transplantation surgery. objective: the aim of this study was evaluation of the effect of ussc on mixed lymphocyte reaction (mlr) as a model for graft rej...
The paper presents a work in the field of ‘mixed reality boundaries’ applied to the visualization of museum collections in order to display the collections ‘live’ as a way to extend virtually the preservation areas of museum collections. To achieve this goal, it was set out to integrate several virtual-studio techniques with multicasting IP in the web and the ‘tectonics’ of museums architecture...
یکی از زمینه های کاربرد منطق فازی سیستمهای کنترل می باشد. دو روش برای استفاده از کنترل فازی در یک سیستم وجود دارد: نرم افزاری و سخت افزاری، پیاده سازی سخت افزاری به دو روش مدارات گسسته و مدارات مجتمع انجام می گیرد. در مدارات مجتمع پیاده سازی به سه روش امکان پذیر است: آنالوگ، دیجیتال و mixed-signal که هر کدام مزایا و معایبی دارند در نتیجه هر روش برای هدف خاصی مفید می باشد. تراشه کنترلر طراحی...
در این کار پژوهشی، شش کمپلکس جدید از سرب(ii) با لیگاندهای دهند? o و n که شامل 2-آمینو پیریدین، 2-آمینو پیریمیدین، نئوکوپرین، 1و10-فنانترولین، 2و2َ-تیو دی استیک اسید، 4و4-دی فلوئورو-1-فنیل-1و3-بوتا دی اون(dfpb) و 4و4و4-تری فلوئورو-1-فنیل-1و3-بوتا دی اون (tfpb)می باشند، سنتز گردید و توسط طیف سنجی ft-ir ، 1h nmr ، 13c nmr و آنالیز عنصری(chn) مورد شناسایی قرار گرفت. از همه کمپلکس ها بروش لوله با شا...
We construct a probabilistic polynomial time algorithm that computes the mixed discriminant of given n positive definite n × n matrices within a 2O(n) factor. As a corollary, we show that the permanent of an n×n nonnegative matrix and the mixed volume of n ellipsoids inRn can be computed within a 2O(n) factor by probabilistic polynomial time algorithms. Since every convex body can be approximat...
