The effect of artificial diffusion schemes on the convergence of an implicit method is investigated. A multigrid code using a symmetric limited positive scheme in conjunction with a lowerupper symmetric-Gauss-Seidel method is developed for viscous compressible flows. The present numerical method is shown to be an effective multigrid driver in three-dimensions. Despite its reasonably fast conver...

The minimax problem is of fundamental importance in nonlinear analysis and, especially, plays an important role in mathematical economics and game theory. The purpose of this paper is to obtain some minimax theorems for mixed lowerupper semi-continuous functions in probabilistic metric spaces which extend the minimax theorems of von Neumann types [1, 3, 4, 5, 6, 8, 10, 11, 12]. As applications,...

conclusions ultrasonography seems to be a safe and cost effective method to evaluate foreign bodies, especially radiolucent objects, in patients with penetrating trauma and suspicious of foreign bodies that may remain undiagnosed in radiography. availability of bedside ultrasound for emergency physicians is an important issue, since it is not possible to access the radiologist at any time of th...

This paper presents an investigation of approaches to modeling lower and upper subjective probabilities. A relatively unexplored approach is introduced, based on the fact that every cumulative distribution function (CDF) with support (0,1) has a “dual” CDF that obeys the conjugacy relation between coherent lower and upper probabilities. A new 2-parameter family of “CDF-Quantile” distributions w...

discussion the prevalence of mtss was relatively lower in this study comparing to other studies on military personnel. it was not probably due to type of military shoes or exercise area surface (none of them were standardized); it could be due to low intensity trainings and the long intervals between training sessions. results data of all the 181 subjects with the mean age of 30.7 ± 4.68 years ...

background selection of anesthetic approach for lower extremity operations is often a controversial issue for anesthesiologists. objectives the aim of this study was to compare the incidence and severity of back pain between general and spinal anesthesia, and to find effective factors in developing postoperative back pain. patients and methods in a randomized clinical trail, 148 patients with e...

arthrogriposis is a disorder in which two or more joints in more than one limb of body, place in a stable position and malformation status that usually is the result of joints' immobilization during fetal period. problems resulting from this congenital deficit can occur in difference places, in upper and lower limbs, trunk, and even in face. it occurs in 3 of 1000 births, in two-third of t...

a b s t r a c t mortality and morbidity from trauma continues to be a serious, ubiquitous public health problem. our short communication reports on the benefits of a dedicated lower limb trauma coordinator (lltc) to the trauma service of a busy inner-london plastics unit. this is based on a retrospective case-note based audit; performed 19 months prior to the introduction of the lltc and for 16...

background: little is known about the influence of habitual participation in physical exercise and diet on upper-extremity physical function in older adults. to assess the relationship of general physical exercise and diet to upper-extremity physical function and pain intensity in older adults.   methods: a cohort of 111 patients 50 or older completed a sociodemographic survey, the rapid assess...

abstract objectives: the purpose of this study was to investigate the relationship between core stability and lower extremity injuries in female athletes through functional tests. decreased core stability has been suggested to contribute to the etiology of lower extremity injuries. so far researches had been used non-functional tests to assess the core stability. material and methods: fifty col...
