background traumatic brain injury (tbi) is an important public health problem throughout the world. objective this study assesses repeated glasgow coma scale (gcs) scores to predict the severity of tbi and survival of the patients. materials and methods a sample of 239 patients who were hospitalized with traumatic brain injury was selected by random sampling from icu wards at shahid beheshti ho...

Background: Lower extremity injuries are frequently observed in car-to-pedestrian accidents and due to the bumper height of most cars, knee joint is one of the most damaged body parts in car-to-pedestrian collisions.Objective: The aim of this paper is first to provide an accurate Finite Element model of the knee joint and second to investigate lower limb impact biomechanics in car-to-pede...

conclusions where there is a relationship between two longitudinal and survival responses, joint modeling can estimate it. background admission to the icu (intensive care unit) is frequently complicated by early aki (acute kidney injury). the development of aki following cardiac surgery is particularly associated with increased mortality and morbidity. according to akin (acute kidney injury net...

Fluid flow in jointed rock mass with impermeable matrix is often controlled by joint properties, including aperture, orientation, spacing, persistence and etc. On the other hand, since the rock mass is made of heterogeneous and anisotropic natural materials, geometric properties of joints may have dispersed values. One of the most powerful methods for simulation of stochastic nature of geometri...

    inventory model,   backorder   buyer ,   vendor,   lot for lot policy In this paper, an inventory model for two-stage supply chain is investigated. A supply chain with single vendor and single buyer is considered. We assume that shortage as a backorder is allowed for the buyer and the vendor makes the production set up every time the buyer places an order and supplies on a lot for lot basis...

Background and Objectives: The cause and pathophysiology of rheumatoid arthritis has not been fully understood and an experimental model of this disease is essential for research on the problem. In this research study, establishment and histopathological changes of chronic arthritis due to intra-articula...
