The polymeric membrane is a well-known membrane due to ease
of processing and mechanical stability. These membranes extensively used for
the separation of carbon dioxide from methane but the applications of these
membranes are limited in order to achieve high permeability and selectivity.
In this study the amine polymeric membrane has been fabricated by the addition
of N-methyl-diethanolamine in polyethersulfone solution, the N- methyl-2 pyrrolidone
used as solvent. The characterization of fabricated membrane has been carried
out in order to investigate the morphology, thermal properties and identification
of functional group by using field emission scanning electron microscope, thermo
gravimetric analyzer and fourier transform infrared spectroscopy. The permeability
and selectivity study were also carried out by using pure carbon dioxide and
methane. The permeability and selectivity has been increased as compared to
pure polyethersulfone membrane. |

In recent years, there has been an increase interest in Organizational Citizenship Behavior (OCB) in organizations. Many scholars believe that OCB improves overall organizational efficiency. The main objective of this study was to investigate the relationship between OCB and task performance among 450 employees of Behzisty organization in central provinces of Iran. The study also looked at the influence of gender, age, education and tenure on the relationship between OCB and task performance. Instruments used to collect data were questionnaires on demographic information, organizational citizenship behaviour and task performance assessment for supervisors ratings of performance. Descriptive and inferential statistics were used to analyze the data. Pearson correlation coefficient was employed to analyze the relationship between OCB and task performance. Multiple regressions were used to examine the moderating effect of gender, age, education and tenure on the relationship of OCB and task performance. The results found that there was a significant relationship between OCB and task performance. It was also shown that gender and education moderated the relationship between OCB and task performance. The results have significant implications on the policies of human resource as well as organizations in Iran. |
