This paper presents a mathematical model for flow induced by peristaltic waves through a deformable tube. An incompressible power-law fluid is considered. The two dimensional model is formulated based upon the fundamental equation of mass conservation and momentum. Exact analytical solutions...

We consider incompressible, magnetohydrodynamic (MHD) third grade fluid confined in a circular cylindrical tube. The tube surfaces are electrically non-conducting. Travelling sinusoidal wave is imposed on the tube which induces peristaltic motion in the fluid. The stream function, axial velocity...

Energy consumption and CO2 emissions caused by gaming industry have never been explored, while gaming industry across the world has experienced considerable development. To fill this blank, a comprehensive analysis based on systems accounting is conducted in this study for embodied energy...

As a typical heterotrophic city, Macao׳s economic boom is fueled by external trade, which provides Macao with not only direct energy products in forms of oil, gas and electricity, but also indirect energy embodied in other imports. However, the prevalent studies on Macao׳s energy issues are...

Fossil energy burning is one of the most important sources of atmospheric mercury emissions, which poses great threats to both environment and human health. Urban regions are dominant energy consumers; however, the information on the resultant mercury emissions in urban regions has been lacking....

In order for service companies to have satisfied customers, they need satisfied employees (George, 1977). Internal marketing aims to encourage employees to be customer oriented which in turn should lead to delivering better service quality and satisfied customers. Research on internal marketing...
