The underlying examination of considering porosity was done by El-Shehawey et al. [9].
Later, the effect of porous boundaries on the peristaltic flow of viscous incompressible fluid was carried out by El-Shehawey and Husseny [10], and they obtained the series solutions for mean axial velocity.
Later, Nadeem and Akram [11] reinvestigated the work done by El-Shehawey and Husseny [10] by taking linear Maxwell model and discussed the effects of various physiological parameters on mean velocity.
Further, the outcomes of the model are in accordance with the results of Manjunatha et al. [33].
Furthermore, from the present model, one can infer the results of a Shapiro et al. [2] for a Newtonian fluid without .

Modelling of Surface Roughness in Ultra-High Precision Turning of an RGP Contact Lens Polymer LIMAN Muhammad1, ABOU-EL-HOSSEIN Khaled1,a*, JUMARE Abubakar1, ODEDEYI Peter1 and LUKMAN Abdulqadir1 1Precision Engineering Laboratory, Department of Mechatronics, Nelson Mandela Metropolitan University, Port Elizabeth 6031, South Arica aKhaled.Abou-El-Hossein@nmmu.ac.za Keywords: Surface roughness, Contact lens, Ultra-high precision turning, Prediction model, Cutting parameters, Diamond tool Abstract.
Khatri et al. [4] studied the effect of machining parameters on surface roughness during diamond turning of polycarbonates.
Goel et al. [5] also observed the surface roughness and waviness during machining of polycarbonate.
Fnides et al. [9] used the full factorial design for three cutting factors in developing new model for estimating the surface roughness in turning hardened hot work steel using mixed ceramic tool.

Moreover, the pounding between the girder and abutment was also investigated by Maragakis et al [7].
According to the nonlinear analyses conducted by Deng et al. [10], the proper value of shear key stiffness was proposed and the effects of restitution coefficient and initial gap were also discussed.
The El-Centro excitation wave, shown in Fig. 3, is exerted in the cross-sectional direction at the bottom of the piers as seismic load.

Hetnarski and Ignaczak in their literature review[7] pointed out five generalizations to the coupled theory:L-S theory, G-L theory,H-I theory,G-N theory of type (II), G-N theory of type III and C-T theory.Recently,Kumar[8],Deswal[9],Othman et al.[10], El-Karamany[11], Song[12], Singh[13,14], Kumar and Sharma[15] have studied various problems on wave propagation at interface between different half-spaces with microstructure by micropolar elasticity theory, micropolar generalized thermoelasticity theory or micropolar generalized thermoviscoelasticity theory.
