Background: To determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves. Methods: All Adolescent Idiopathic Scoliosis (AIS) patients included in the study were classified according to Lenke and King Classification. The fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt...
background: to determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves. methods: all adolescent idiopathic scoliosis (ais) patients included in the study were classified according to lenke and king classification. the fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt of t1 an...
background: rhabdomyosarcoma is a rare malignant soft tissue sarcoma and the most common sarcoma of childhood. the purpose of this study was to investigate the distribution of age and sex of patients, pathological subtypes and to determine the role of staging and classification of rms on treatment outcome. materials and methods: this retrospective study included patients who diagnosed with rms ...
the notion of $f$-derivations of up-algebras is introduced, some useful examples are discussed, and related properties are investigated. moreover, we show that the fixed set and the kernel of $f$-derivations are up-subalgebras of up-algebras,and also give examples to show that the two sets are not up-ideals of up-algebras in general.
Background: The role of arthroscopic partial meniscectomy (APM) for painful degenerative meniscal tears (PDMT) is currently controversial. To define the rate of early (1 to 5 years) conversion to total knee replacement (TKR) and their predictors after APM for PDMT in patients with knee osteoarthritis and more than 50 years of age. Methods: Retrospective cohort study of patients more than...
Background: Despite several years of intensive investigation, relatively few studies have been made of children with lupus nephritis. The prognosis of children with lupus nephritis is poor for those with diffuse proliferative glomerulonephritis and active interstitial inflammation. As newer treatment modalities become available for patients with severe lupus nephritis, it become increasingly im...
در این پایان نامه، الگوریتم پیمپل که ترکیبی از الگوریتم های پیزو و سیمپل می باشد، برای شبیه سازی جریان تراکم پذیر در تمامی محدوده های اعداد ماخ، از جریان مادون صوت گرفته تا مافوق صوت، توسعه یافته است. با استفاده از روش تعیین شار ausm+-up به عنوان جایگزین درونیابی رای و چو، این الگوریتم می تواند از مزایای روش ausm+-up در اعداد ماخ بالا و کارایی روش های فشارمبنا در جریان هایی با اعداد ماخ پایین ا...
این تحقیق با وارد کردن لانتاتیدهایی چون هلمیوم (3+ho) ایتربیوم (3+yb) نئودیمیوم (3+nd) به صورت تکی یا چندتایی، به یک میزبان شیشه فسفاتی، نمونه های مختلف شیشه – سرامیک تحت عملیات حرارتی ساخته شده است. بعد از طیف نگاری های xrd و طیفهای عبور و جذب و فلورسانس گسیلی، ورود لانتانیدها به فاز نانوکریستالی cacl2 بررسی شده است. به واسطه خصوصیات ذاتی لانتانیدها در توانایی جذب و گسیل نور و شکافت تراز های ...
Background and Objective: The Gross Motor Function Classification System Expanded and Revised (GMFCS E&R) has been widely utilized for objective classification of gross motor function of patients with cerebral palsy (CP). The aim of this study was to evaluate the inter rater reliability of Persian version of GMFCS E&R in patients with CP. Materials and Methods: This was a descriptive analytic s...
Introduction: One of the leading causes of death among people is brain tumors. Accurate tumor classification leads to appropriate decision-making and providing the most efficient treatment to the patients. This study aims to optimize of the brain tumor MR images classification accuracy using the optimal threshold, PCA and training Adaptive Neuro Fuzzy Inference System (ANFIS) w...
