    Abstract: Omeprazole is a potent proton pump inhibitor for the treatment of various acid-related gastrointestinal disorders. simple, selective and rapid reversed phase high performance liquid chromatographic (RP-HPLC) method for the analysis of Omeprazole has been developed and validated. The separation was achieved from HPLC column (ZORBAX, XDB, C-18 (150×4... Show More

    Abstract: For a chute with a large elevation difference, it is important to choose the right inclination of chute, both to ensure the material will accelerate at a steady flow in the chute, and to meet the requirements of flow speed. In this situation the chute inclination cannot be determined according to conventional methods for a single factor, because in... Show More

    Abstract: This paper reports a transient state numerical investigation of irreversibility in a saturated porous channel, of an aspect ratio A= 5, under vertical thermal and mass gradients. The governing equations, using the Darcy-Brinkman formulation, have been solved numerically by using Control Volume Finite Element Method (CVFEM). Only two variables are t... Show More
