An exact solution of the steady three-dimensional Navier-Stokes equations is obtained for the case of flow past a porous plate at zero incidence in a rotating frame of reference. For uniform suction at the plate, an asymptotic profile exists for the velocity distribution.

Saturates, aromatics, resins, and asphaltenes (SARA) analysis by thin-layer chromatography–flame ionization detector (TLC–FID) is a fast and efficient technique for group-type analysis of hydrocarbon residues. The present paper attempts to provide a new method for measurement of SARA fractions of whole crude oils using TLC–FID while addressing the issues related to FID calibration and loss of lighter hydrocarbon components during analysis. The experimental results obtained by the new method are compared to the traditional methods.

The paper presents a study of propagation of Love waves in a poroelastic layer resting over a poro-elastic half-space. Pores contain nothing of mechanical or energetic significance. The study reveals that such a medium transmits two types of love waves. The first front depends upon the modulus of rigidity of the elastic matrix of the medium and is the same as the love wave in an elastic layer over an elastic half-space. The second front depends upon the change in volume fraction of the pores. As the first front is well-known, the second front has been investigated numerically for different values of void parameters. It is observed that the second front is many times faster than the shear wave in the void medium due to change in volume fraction of the pores and is significant.
