In the present paper, we have studied the propagation of axial symmetric cylindrical surface waves through rotating cylindrical bore in a micropolar porous medium of infinite extent possessing cubic symmetry. The frequency equation for surface wave propagation in the micropolar porous medium has been derived and liquid filled bore are derived. The effect of the rotation on phase velocity of surface wave has been studied in detail. Radius of bore and other material parameters for empty and liquid filled bore are derived. A particular case of interest has been deduced. Numerical results have been obtained and illustrated graphically to understand the behavior of phase velocity versus wave number of a wave. The results have indicated that the effect of rotation on phase velocity is highly pronounced. Comparisons are made in the absence of rotation.

Agricultural soil and wells water that used for irrigation and drinking may contain high levels of toxic trace elements. In this study the concentration of Al, Ni, Co, Mn, Cr, Pb, As and Cd in agricultural soil and wells water samples from Turabah Province (Saudi Arabia) were determined by usingI nductively coupled plasma optical emission spectrometer (ICP-OES) and microwave acid digestion techniques for soil samples. According to limit of detection (LOD) Co was not detected in all samples, while other studied trace elements (TEs) were detected in different concentrations values according to type and location of the sample. Further more, Al recorded at high values of concentration in some soil samples. The analysis method was validated in terms of accuracy, precision, limit of detection (LOD) and limit of quantification (LOQ) and confirmation reliability. The recovery percent was found to be between 91.6-103.4%.
