a simple analytical system suitable for nephelometric measurements is introduced in this article. the electronic and optical components are simplified so that the apparatus is easily assembled from materials that are generally available. this instrument is designed for the efficient measurement of anions, and microgram quantities of ions may be determined by a convenient method of titration. us...

In this contribution, linearized dynamic model of Cumulative Mass Fraction (CMF) of Potassium Nitrate-Water Seeded Continues Mixed Suspension Mixed Product Removal (CMSMPR) crystallizer is approximated by a simplified model in frequency domain. Frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. However, the CM...

PURPOSE Opioid-based intravenous patient-controlled analgesia (IV PCA) is popular method of postoperative pain control, but many patients suffer from IV PCA-related postoperative nausea and vomiting (PONV). In this retrospective observational study, we have determined independent predictors of IV PCA-related PONV and predictive values of the Apfel's simplified risk score in pursuance of identif...

To systematically measure and compare the stress distribution on the bone around an implant in the anterior maxilla using angled abutments by means of finite element analysis, three-dimensional finite element simplified patient-specific models and simplified models were created and analyzed. Systematically varied angled abutments were simulated, with angulation ranging from 0° to 60°. The mater...

The present quasi-experimental study mainly investigates the role of literature as input for reading comprehension in Iranian EFL classrooms. To be more exact, it investigates the effects of authentic and simplified literary texts on the reading comprehension of Iranian advanced EFL learners. The participants were 35 male and female Iranian EFL learners who were at advanced level, studying in a...
