Abstract Geophysical Investigation of Anambra South River Basin of Nigeriahas being studied This research work presents the methods of exploration with particular reference to the Electrical resistiviy method as used in determining the hydrogeology of some parts of Anambra South. Vertical Electrical sounding (VES) is utilized using the digital electronics Device, ABEM 300B Tetrameter with Schlumberger array. The hydrogeological provinces of the study area is: The Eastern lowland and the Western upland. The former is underLaid by the Imo formation while the letter is under laid by Ameki /Nanka and Ogwashi-Asaba formations. Results from data analysis and interpretation shows that clay and sand Formations are the predominant lithology within the study area. The aquiferous formation Lies within sand, clayey sand and sandstone lithology. Sands and sandstone appear to Have large thickness across the horizons and locations, the thickness of the horizons Varies between (1.20- 122.00) meters
Publication Title Progress has been made in the experimental determination of the phonon bandstructures of some materials, and further progress is expected. Therefore an accuratedetermination is clearly desirable. In this paper, we studied the phonon band structures of some FCC metals (A1, Ni)and some BCC metals (Na, Nb) with the help of QUANTUM ESPRESSO packagewhich is based on the density functional theory (DFT) within the local densinapproximation (LDA). The result obtained compare favorably to other' works inliterature. The motivation is to assess the power of the code in the computation of phononsbeginning with well-known materials, such as Al and Na. Download PDF
