Using an Electric Differential (ED) in electric vehicle has many advantages such as flexibility and direct torque control of the wheels during cornering and risky maneuvers. Despite its reported successes and advantages, the ED has several problems limits its applicability, for instance, an increment of control loops and an increase of computational effort. In this paper, an electric differenti...
in this work, we conduct a comparative study among the combine laplace transform and modied adomian decomposition method (lmadm) and two traditional methods for an analytic and approximate treatment of special type of nonlinear volterra integro-differential equations of the second kind. the nonlinear part of integro-differential is approximated by adomian polynomials, and the equation is red...
Background Measuring and understanding main determinants of length of stay (LOS) in emergency departments (EDs) is critical from an operations perspective, since LOS is one of the main performance indicators of ED operations. Therefore, this study analyzes both the main and interaction effects of four widely-used independent determinants of ED-LOS. Methods The analysis...

زمینه و هدف: اختلال نعوظ(Erectile Dysfunction) یک مشکل شایع پزشکی بوده و شیوع آن در جمعیت بیماران مبتلا به بیماری عروق کرونری بیشتر است. بسیاری از ریسک فاکتورهای ED با بیماری عروق کرونر مشترک بوده و لذا ED به عنوان Risk equivalent Coronary Artery (CAD)Disease پذیرفته شده است. از این رو هدف از این مطالعه بررسی یافته های آنژیوگرافیک شریان پودندال داخلی در بیماران کاندید آنژیوگر...
We studied the hepatotoxic effects of a deltamethrin containing formulation (Decis®) on developing em-bryo of Gallus domesticus. Fertilized eggs were immersed in three different concentrations of deltamethrin (12.5, 25 and 50 mg/L) for 60 min at 37 ˚C prior to incubation (ED 0) and on the 4th day of incubation (ED 4) and incubated till embryonic day (ED) 16. Exposure to 50 mg/L of deltamethrin ...
Introduction: The effect of esophageal distension (ED) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ED on gastric secretion. The aim of this study was to investigate the effect of ED on gastric acid and pepsin secretion and the mechanism(s) involved. Methods: Male adult Wistar rats (200-240 g) were anesthetized with urethane (1...
