Geophysical Site Investigation for Groundwater Prospecting in the Permanent Site of Federal University, Dutsin-Ma, Nigeria

Geophysical investigation of the permanent site of Federal University, Dutsin-Ma located in Katsina State site was carried out with the objective of investigating the subsoil conditions based on geophysical site exploration methodology in order to take precise engineering decisions on the best locations for different utilities and ground water profile establishment. The major instruments used in carrying out the fieldwork include: SAS 300, Reels of cables, sets of electrode, hammer, tapes and sealed battery. Six survey profiles were used with 200m length each. Dedicated geophysical software was used for the data processing. Results show that the thickness of the overburden which ranges between 2 m to 35 m is more in the southern part of the survey area than the northern part that has thin overburden thickness. This suggests that the thickness of the underground water aquifer will be more in the southern part of the survey area. Best locations of boreholes were recommended and alternative source of water was suggested based on observation.Keywords: Fresh basement, Geophysics, Resistivity imaging, Site investigation, Subsoil exploration, Aquifer

Mobile Robot in the Clean Room - SEL-CARRY ACE -

Shinko Electric has commercially introduced a ""SELCARRY ACE"" system of mobile robots for material transfer in clean rooms. The ACE is a new type of guided transfer robot that relies on ultrasonic sensors to check on the physical environment along its running route, uses the data thus obtained to determine its position, and runs accordingly on its own accord. A six-axis vertical articulated arm installed on the robot transfers objects between stations in the room. A sealed battery rechargeable automatically in a short time enables the unmanned ACE to run continuously. Since the battery can be recharged quickly while an object is being transferred, these features enables the user to construct a highly efficient transfer system.
