A case study of aeromagnetic data interpretation of Nsukka area, Enugu State, Nigeria, for hydrocarbon exploration

The aeromagnetic data of Nsukka area was interpreted qualitatively and quantitatively. Standard Euler deconvolution, Source Parameter Imaging (SPI), Forward and Inverse modeling techniques were employed in quantitative interpretation with the aim of determining depth/thickness of the sedimentary Basin, magnetic susceptibilities and type of mineralization prevalent in the area. Oasis montaj 6.4.2 software and potent...

Ab-initio calculations of magnetic behavior in wurtzite AlxV1-xN compound

The density functional theory was employed in order to study the structural, electronic, and magnetic properties of the AlxV1-xN (x=0.25, 0.50, and 0.75) compound in the wurtzite-type structure. The calculations were executed using the method based on pseudopotential, employed exactly as implemented in Quantum ESPRESSO code. For the description of the electron-electron interaction, generalized gradient approximation...
