Unsteady equation for free recharge in a confined aquifer
Slug test solutions require instantaneous water column in the recharge well, and it consider well storage and well loss not appropriate for recharge cases. State of the art suggests recharge hydraulics, a phenomenon synonymous to mirror image of well pumping. In this background, the present paper derives fresh semi-analytical equations for confined aquifer, which simultaneously determine unsteady recharge...

Sr-Nd-Pb isotopic studies of lavas of Mt. Oku volcano, North West Cameroon: A case involving HIMU, depleted and enriched mantle sources
Sr-Nd-Pb isotopic studies have been carried out on the lavas of Mt. Oku, the central part of the continental sector of the Cameroon volcanic line (CVL). The lavas define a considerable range of Sr-Nd-Pb isotopic compositions characterized by 143Nd/144Nd = 0.512626 – 0.512937,87Sr/86Sr = 0.699411 - 0.704279 and more radiogenic isotopic ratios 206Pb/204Pb = 18.3800 –...
