background and objective: the anemia of esrd is a complex disorder, associated with serious complications, which increases patients’ mortality and morbidity. treatment of this anemia with recombinant human erythropoietin (rh-epo) is well established. this clinical trial study was conducted within 20 months, from may 2005 to december 2006, in order to evaluate the efficacy of pdpoetin (rh-epo al...

This study is the result of an attempt to investigate the differences between the Persian translated drama text (page) of each English drama text with its performance on the stage (stage) in Iran. In other words, the present researchers tried to find the implemented changes in page which make it real on the stage in the target language and culture in order to show that in drama translating and ...

In this work, single-stage and two-stage tubular solid oxide fuel cell (SOFC)/gas turbine hybrid cycles are comparatively examined from the energy and exergy viewpoints. For this purpose, mass, energy and exergy balances are applied to all components of the cycles. The behavior of tubular solid oxide fuel cell modeled in this study is validated with the experimental test data of tubular SOFC de...

We consider a stage life testing model and assume that the information at which levels the failures occurred is not available. In order to find estimates for the lifetime distribution parameters, we propose an EM-algorithm approach which interprets the lack of knowledge about the stages as missing information. Furthermore, we illustrate the implementation difficulties caused by an increasing nu...

Large wood (LW) is an important feature in many streams in northeastern North America, yet the dynamics (recruitment, movement, and export) of large wood remain largely undocumented for streams in this region. In this study we quantify the dynamics of LW in 400 m of a second-order, high gradient, boulder-dominated stream in the eastern Adirondack Mountains, NY. Characteristics and location of a...

 Abstract Background: Rehabilitation of facial paralysis is one of the greatest challenges faced by reconstructive surgeons today. The traditional method for treatment of patients with facial palsy is the two-stage free gracilis flap which has a long latency period of between the two stages of surgery. Methods: In this paper, we prospectively compared the results of the one-stage gracilis flap ...

1. Comparative research and generalisations in lotic ecology are challenged by the dynamic hydrology of fluvial systems. The aim of this study was to understand more fully how factors such as light, nutrients and flow can predict variation in autochthonous production and algal biomass. 2. We measured seasonal changes in percent bankfull discharge, inorganic nutrient concentrations, turbidity, i...
