BACKGROUND Esophagogastroduodenoscopy (EGD) is useful in the diagnosis and evaluation of dyspepsia. We investigated factors that might be associated with self-reported patient tolerance of EGD and therefore might serve as objective, reliable and useful surrogates for self-reported patient tolerance. We also investigated factors that might influence EGD(More)
Mercury (Hg) is one of the main global pollutants that may biomagnify in food nets, especially in wetlands. Birds may be useful in the biomonitoring of Hg in such habitats and may even serve in vivo samples. This paper examined Hg concentration in the feathers of seven bird species foraging on Fereydunkenar International wetland (in 2013). Mean Hg(More)
In this study, an accurate analytical solution for Duffing equations with cubic and quintic nonlinearities is obtained using the Homotopy Analysis Method (HAM) and Homotopy Pade technique. Novel and accurate analytical solutions for the frequency and displacement are derived. Comparison between the obtained results and numerical solutions shows that only(More)
