Abstract: Direct Current Resistivity investigation for engineering studies was carried out around the Kaduna Refining and Petrochemical Corporation Industrial Layout within the Basement Complex of Central Nigeria. The study aimed at evaluating the competence of the near surface formation meant to aid in foundation design and other related engineering structures, and to unravel the subsurface profile which in turn determines if there would be any subsurface geotechnical parameters and lithological variation(s) that might lead to structures failure within the site. A total of twenty-two (22) VES statins were established. The data obtained were subjected to 1-D inversion algorithm to determine the layer parameters. The geo-electric section revealed three to five lithological units defined by the lateritic topsoil, silty/sandy/clayey, the weathered basement as well as the fresh basement. The resistivities and thicknesses of the topsoil range from 100 Ωm – 2668 Ωm and 0.3 m – 6.4 m respectively. The last layer considered as the fresh basement and in some cases the fractured basement has an infinite thickness with resistivity ranging from 610 Ωm – 79674 Ωm and the established average overburden thickness of the study area was found to be 23 m. A broad portion of the area was found to be competent for civil works except at VES stations C6 and D4 with relatively low topsoil resistivity. The competent regions have been recommended for major construction works such as high rise buildings, bridges and roads.

Abstract: This research paper focuses on the study of Spherical Langmuir Probe I-V characteristics in Maxwellian space plasma. This work is conducted using computational techniques to create the exact plasma conditions of the experimental testing environments. The investigations address the development of a technique to model Maxwellian plasma. Three different sized Langmuir probes has been designed theoretically for ionospheric temperature 0.5eV, with the help of computational techniques; I-V traces are produced to analyze the plasma parameters. The variation of floating potential due to probe size is clearly depicted. A manifest trail in the I-V curves is the bump that occurs right after the floating potential. This feature in the transition region affects ability to determine the electron temperature, ion saturation current and plasma potential.

. The four-vector mathematics in this complex plane agrees with the three-dimensional vector mathematics that is well established. This study therefore intends to comprehensively reformulate geodetic effect and frame-dragging effect.
