Abstract This research applied the geoelectric method to determine presence of aquifer layers in Bumi Harapan village. can value subsurface resistivity, and from this value, will know lithology based on distribution resistivity. The results be described form resistivity logs make it easier find groundwater layer its depth. Subsurface obtained structures topsoil, clayey sand, sandy clay clay. su...

Electrical resistivity method was used in carrying out geophysical investigations at the Centre for Energy Research and Training (CERT), Ahmadu Bello University, Zaria, with a view of determining the depth to the bedrock, thickness of the top soil and weathered basement.Vertical Electrical Sounding (VES) using Schlumberger array was carried out at forty (40) VES stations. ABEM terrameter (SAS 3...

Sediments undergo several modifications to become the source rocks, reservoirs and seals that generate and contain petroleum reserves. The changes that occur between deposition and lithification, collectively known as diagenesis, include the processes of compaction, cementation, dissolutio...

because of urgent needs of groundwater resources in the tochal region of north tehran, an integration of electric and electromagnetic methods was applied to investigate the location and the direction of water bearing fractures. first, the vlf electromagnetic profiling was performed on suitable places and two locations were detected for supplementary resistivity surveys. then, a number of vertic...

Thyroid nodules are common, affecting from 5 to 15% of the population (Tunbridge et al., 1977; Vander et al., 1968). Thyroid cancer, on the other hand, is uncommon and represents only 5% of all nodules, with an incidence in the United States of 1/10,000 inhabitants (Davies & Welch, 2006). Among thyroid neoplasms, the differentiated carcinomas (DTC) are the most frequent, and are responsible for...
