A computational investigation on the structural features of alkanolamine solvents for CO2 capture process from power plant flue gas

EFL Learner’s Evaluation of Writing Tasks in Iran’s TOEFL and IELTS Preparation Courses in Light of the Process-oriented Approach

The purpose of this research was to analyze EFL writing tasks in two of the most popular English for Speakers of Other Languages (ESOL) exam preparation courses in Iran, namely IELTS and TOEFL. Having collected the criteria of writing task appropriateness in light of the process-oriented approach to writing instruction, we asked 60 learner participants to rate EFL writing tasks in 3 IELTS and 3...

An investigation of reactive behavior of yellowfin tuna schools to the purse seining process

The movement parameters of yellow fin tuna schools were analyzed by means of scanning sonar in tuna purse seine capture situations in the Oman Sea in June 2010. There was significant difference in swimming speed and radial swimming direction between the escaped and captured schools. In escaped cases, the fish schools swam faster with mostly horizontal avoidance behavior to the sound stimuli fro...

Investigation of carbon dioxide capture from hydrogen using the thermal pressure swing adsorption process: Central composite design modeling

In this study pre-combustion capture of carbon dioxide from hydrogen was performed using a 5A zeolite adsorber. A one column thermal pressure swing adsorption (TPSA) process was studied in the bulk separation of a CO2/H2 mixture (50:50 vol%). The adsorption dynamics of the zeolite bed were investigated by breakthrough experiments to select the suitable range for operational factors in the desig...

Optimal Process Adjustment with Considering Variable Costs for Uni-variate and Multi-variate Production Process (RESEARCH NOTE)

This paper studies a single-stage production system, two-stage production system where specification limits are designed for inspection. When quality characteristics fall below a lower threshold or above an upper threshold, a decision is made to rework or scrap the item. The target is to determine the optimum target for a process based on rework or scrap costs. In contrast to previous studies, ...
