Combined Electrical Resistivity Imaging and Electromagnetic Survey for Groundwater Studies in the Tarkwa Mining Area, Ghana

Heavy metals level in streams of Tarkwa gold mining area of Ghana

Heavy metals concentrations in water and sediment samples collected from five streams in Tarkwa gold mining district of Ghana were studied. The water and sediment samples were analysed for As, Al, Cd, Co, Cu, Hg, Mn, Sb, Th, and V, using Instrumental Neutron Activation Analysis (INAA). The results of this study generally showed elevated levels of all the ten examined elements in the water and s...

Coastal groundwater dynamics off Santa Barbara, California: Combining geochemical tracers, electromagnetic seepmeters, and electrical resistivity

This paper presents repeat field measurements of 222Rn and 223,224,226,228Ra, electromagnetic seepage meter-derived advective fluxes, and multi-electrode, stationary and continuous marine resistivity surveys collected between November 2005 and April 2007 to study coastal groundwater dynamics within a marine beach in Santa Barbara, California. The study provides insight into magnitude and dynami...

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Informed experimental design for electrical resistivity imaging

Electrical resistivity imaging has been successfully used to monitor near-surface hydrologic processes but use of standard measurement arrays may not provide the greatest data sensitivity to the imaged region. We present a method of experimental design based on the concept of informed imaging for creating an electrical resistivity imaging experiment to monitor flow beneath a recharge pond. Info...
