background: risk of malignancy index (rmi) is the best method for discriminating benign and malignant pelvic masses. the aim of this study was to determine the rmi for preoperative evaluation of pelvic mass. methods: this study was performed on 182 women with adenexal mass referred to yahyahnejiad hospital of babol university of medical sciences in iran from 2007 to 2009.the sensitivity, specif...

background: assessment forms the backbone of undergraduate medical training especially in clinical contexts and clerkships, which are typically situated in environments lacking educational structure. this study aims to evaluate the viewpoints of medical interns in internal medicine, surgery, pediatrics and obstetrics and gynecology wards about feedback and formative assessment. methods: 100 med...

background and objective: the reliability and validity of monitors for self-monitoring of blood glucose are debated. we evaluated the analytical performance of accu-check active (boehringer mannheim, roche) which is one of the most commonly used monitors in iran. material and methods: we compared the monitor readings with the reference values by percentage of values within certain intervals of...

in this paper we apply the technique of measures of noncompactness to the theory of infinite system of integral equations in the fr´echet spaces. our aim is to provide a few generalization of tychonoff fixed point theorem and prove the existence of solutions for infinite systems of nonlinear integral equations with help of the technique of measures of noncompactness and a generalization of tych...

in this paper, we prove a common fixed point theorem for six mappings (two set valued and four single valued mappings) without assuming compatibility and continuity of any mapping on non complete metric spaces. to prove the theorem, we use a non compatible condition, that is, weak commutativity of type (kb). we show that completeness of the whole space is not necessary for the existence and uni...

g. darbo [rend. sem. math. univ. padova, 24 (1955) 84--92] used the measure of noncompactness to investigate operators whose properties can be characterized as being intermediate between those of contraction and compact operators. in this paper, we apply the darbo's fixed point theorem for solving infinite system of linear equations in some sequence spaces.

a class of new methods based on a septic non-polynomial spline function for the numerical solution of problems in calculus of variations is presented. the local truncation errors and the methods of order 2th, 4th, 6th, 8th, 10th, and 12th, are obtained. the inverse of some band matrixes are obtained which are required in proving the convergence analysis of the presented method. convergence anal...
