medication errors have important effects on increased length of hospitalization, increased mortality and costs. we assessed the incidence of medication errors and characterize the error types in an emergency department in a large teaching hospital in tehran. we also investigated the effect of emergency department pharmacists on patient safety with regard to recovery of potentially harmful medic...

Writing skill has been considered the most challenging part of foreign language learning. This situation may be because writing is not innate and requires cognitive skills learners. While writing, learners must able to perform different activities simultaneously (Flynn & Stainthorp, 2006). The area learners’ errors heavily researched many would like find causes problems help in improving th...

PURPOSE To investigate mathematically and experimentally the sources of errors in localization of COMS-type plaques in melanoma brachytherapy when using ultrasound and transillumination and to give recommendations to avoid such errors. METHODS A computer-aided simulation tool was developed to model the errors seen in the patient images when using ultrasound imaging and transillumination durin...

We consider the sources of forecast errors and their consequences in an evolving economy subject to structural breaks,forecasting from mis-specified, data-based models. A model-free taxonomy of forecast errors highlights that deterministic shifts are a major cause of systematic forecast failure. Other sources seem to pose fewer problems. The taxonomy embeds several previous model-based taxonomi...

medication errors (mes) are the most common error in icus. in fact, 78% of all serious errors in icus are due to mes. therefore, detecting mes has vital significance. the goal of this study was to investigate the frequency, type and consequences of different types of errors including prescribing, transcribing and administration errors in an icu of a large teaching hospital. disguised direct obs...

INTRODUCTION: In WDM soliton systems, the main sources of timing jitter (TJ) include the Gordon-Haus (GH) effect, soliton-soliton collisions (SSC), the acoustic effect, and the polarization mode dispersion. Although TJ from the GH effect is random from pulse to pulse, other sources lead to nonrandom TJ. Because the time displacements from the nonrandom sources highly depend on the pattern of tr...

background and aim. knowledge of the common radiographic errors and their prevention could prevent imposing redundant radiation, time and money to patient and the dentist. the aim of this study was to assess the common radiographic errors on panoramic radiographs in a radiology department. materials and methods. 250 panoramic radiographs (100 male and 150 female; mean age, 24.3) taken at the de...

A proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. This paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. For this aim, DST and PVT data of exploration and production wells of a supergiant offshore gas condensate reserv...
