Modeling teachers' influence on learners' self-directed use of electronic commerce technologies outside the classroom
Nowadays, Electronic Commerce (EC) course is becoming one of the most important taught courses at all business schools due to increased businesses over the Internet network by utilizing all available technologies. However, the success of such courses cannot be measured by number of students who pass or fail but rather by how such courses influence and can change the daily life of these students. Previous literature...

On the computational fluid dynamics (CFD) analysis of the effect of jet nozzle angle on mixing time for various liquid heights
In the present work, the effect of nozzle angle (22.5º, 45º and 67.5º) on mixing time for jet mixing tanks with the various ratios of liquid height (H) to tank diameter (D), including 0.5, 1, and 1.5, are studied by using computational fluid dynamics (CFD). The results revealed that CFD model with standard k-epsilon is successfully employed to predict the concentration profiles and mixing time by using...
