- ItemEffect of Prenatal Exposure to Electromagnetic (2.45 GHz) Radiation on Liver Organ of Albino Rat’s Offspring(Adeleke University journal of science, 2025-06) Oyero O P; Amuda D B; Adeleke D K; Ajani Adegbenro Sunday; Aremu A A; Egbeyale Godwin B; Oyero A B; Oni A AThis study was aimed to examine the effect of 2.45 GHz radiofrequency radiation prenatal exposure on the liver of first filial generation (F1) of albino rats. Two specially designed electromagnetic field cages containing three (3) pregnant rats each were marked as experimental exposed group (EEG) and control unexposed group (CUG) in this study. A portable radio picostation of RF up to 2.45 GHz with Ubiquitous Network, USA, with its integrated omnidirectional antenna was placed inside the EEG cage at 15 cm proximity to the pregnant rats to serve as RF radiation source. Pregnant rats in CUG cage were kept unexposed. Radiofrequency radiation exposure was performed on pregnant rats in the EEG cage for 1 hour everyday between 13th to 21st day of gestation. Power density of 0.066 W/m2 (5 V/m) was maintained during the period of exposure. After parturition, two new groups namely New-EEG and New-CUG were established from pups obtained from EEG and CUG respectively. Male rat pups from New-EEG and New-CUG were sacrificed on 50th day postnatal and their livers were harvested for histological examination. Result from the photomicrograph revealed degenerated liver in New EEG characterized by a mild loss of liver parenchyma, some mild derangement in the cellular profiles, severe hemorrhage and presence of inflammatory red cells within and around the central vein including the sinusoids as against New-CUG. Result of this study showed that RF radiation prenatal exposure caused morphological changes in the liver of F1 generation of albino rats.
- ItemGeoelectric Assessment of Groundwater Potential in Erin-Ile Basement Region Complex of Southwestern Nigeria(Nig. J. Pure & Appl. Sci., 2025) Olasunkanmi N k; Babawale J A; Egbeyale Godwin B; Oladunjoye H T; Magawatta U Z; Jimoh Y A; Fatola M KThis study presents a geoelectric evaluation of groundwater potential in Erin-Ile, situated in the basement complex terrain, utilizing Vertical Electrical Sounding (VES) to delineate lithological layers and assess aquifer characteristics. The study area relies entirely on groundwater for daily water supply, leading to challenges such as low borehole yields and increased water demand due to population growth and infrastructure development. The resistivity and thickness parameters analyzed to understand the subsurface hydrogeological structure. Notably, the study employs H-Type and KH-type curves to categorize lithological layers as lateritic soil, weathered basement, and fractured/fresh basement. Groundwater potential analyses consider aquifer resistivity, thickness, hydraulic conductivity, and transmissivity. The results indicate varying groundwater potential across the 50 VES points, with transmissivity ranging from -931.6 to 474.37 m²/day. Of these points, 74% are classified as having moderate potential, 24% as having low potential, and 2% as having negligible potential. No locations were identified with high or good groundwater potential. The southwestern part of the study area is predominantly characterized by moderate groundwater potential. This research contributes valuable insights into the hydrogeology of Erin-Ile, offering a foundation for sustainable groundwater resource management. This study provides valuable insights into the hydrogeology of Erin-Ile, emphasizing the importance of geoelectric methods in assessing groundwater potential. The findings highlight opportunities for improving groundwater resource management and optimizing water supply infrastructure.
- ItemCHARACTERIZATION OF THERMAL PROPERTIES BEHAVIOUR OF CLAY IN EKITI STATE, SOUTH WESTERN NIGERIA(Nigerian Association of Mathematical Physics, 2018) Egbeyale Godwin B; Adegoke Jame AThermal quality of material is a useful property in building engineering. Today we deal with increasing requirements for quality of brick products, particularly in terms of thermal properties. These characteristics of products depend on many factors, such as conductivity. This paper presents results of the thermal properties of clay slabs, sampled at five different locations in Ekiti state. KD2 probe was used to determine the thermal properties of the slabs. Thermal conductivity, thermal diffusivity and specific heat capacity range from 0.12 to 0.17 W/mK; 6.62 to 10.9 m2 /s and 8.5x10 3 to 9.85x10 3 J/kgK, respectively. The results are useful data for builders and agriculturists.
- ItemGeophysical Investigation of Building Foundation in Part of Ilorin, North Central Nigeria Using Electrical Resistivity Method(IOP, 2019-10-21) Egbeyale Godwin B; Ogunseye T T; Ozegin K OElectrical resistivity method has been performed using Vertical Electrical Sounding (VES) technique at a Bishop Smith Memorial College, Ilorin, Kwara State to examine the geophysical parameters that can be used to evaluate the subsurface competency. Eight VES stations were sounded, using Schlumberger configuration for data acquisition with current electrode spacing varying from 1.0 to 140.0 m. The VES data obtained were interpreted using ipi2win+ip Software. The field data acquired was presented as geoelectric sounding curves and geoelectric section. The interpretation of the field results revealed heterogeneous subsurface geologic sequence probed to 34.6 m and beyond. It also showed presence of near surface linear geologic structures of varying lengths, depths and attitude which suggest the competent zones for foundation laying. The major subsurface layers are the top soil which consists of interlocking and concretional lateritic stones and clayey sand, weathered basement, fractured basement and fresh basement. For building development in the study area, the topsoil must be excavated to at least the Fresh basement (competent layer) to avoid building deformation.
