Abstract. This paper presents a method for calculating the radiative energy transfer in back and forth approximation case of cylindrically symmetric currents. The key element is scheme heat medium with opacity that strongly varies space time. discusses possibility improving accuracy solving difference equations’ system by making absorption coefficients more accurate. numerical technique propose...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
Background: Musculoskeletal disorders are the most common occupational injuries and constitute a huge global health problem with substantial economic and human cost as well as negative impact on the quality of life. The aim of this study was to determine the prevalence of musculoskeletal disorders and level of risk among the workers of the assembly line of a battery factory. Methods: In this...
In this paper a new authentication system using Finger Back Knuckle Surface is examined. This paper is intended to propose an effectual method for personal authentication using Finger Back Knuckle Surface. This method take advantage of the less number of features extracted from the Finger Back Knuckle Surface and the Angular geometric analysis is done to mine the distinguishable feature informa...
