ABSTRACT Over 200 rock samples representing the major sedimentary, metamorphic and igneous rock units in Afikpo area were collected and various laboratory tests were carried out on them in order to determine their densities and porosities. The objectives are to provide reference materials to researchers who may run gravity traverses within this area and also […]
ABSTRACT The swimming performance, as judged by maximum sustained swimming speed, of African catfish, Heterobranchus longifilis (Val) from a fish farm near Port Harcourt, Nigeria was low when compared to previous published values for this species. This is ascribed to a localized peculiarity resulting from hatchery selection and rearing procedures. Download Full Article
ABSTRACT An investigation of velocity anisotropy was carried out using density and dipole sonic logs comprising compressional and shear interval transit times, acquired between 2000 and 2002 in some well-spaced petroleum wells in the western part of the Niger Delta. The aim of the study was to understand how seismic velocities vary laterally and vertically […]
ABSTRACT Southeastern Nigeria was divided into four geologic basins namely: the Niger delta, Proto-delta, Anambra and the Abakaliki basins. These basins were subsequently divided into grids cells of 100km2 areas and in each cell, azimuthal Schlumberger electrical survey was carried out to determine the degree of electrical anisotropy related to the structural texture and degree […]
ABSTRACT A shorter procedure of determining maximum loss of information in odd fractional 2k factorial experiment has been developed. It serves as a quick check on the confounded effects so that all information on treatment effects will not be lost. Download Full Article
ABSTRACT Water samples were collected from twenty two (22) locations in the Embayment across the periods of dry (January), dry-wet (March), wet (June), wet-dry (September), to highlight the micro-climatic conditions between January to September 2005. The main objectives of this work were to carry out hydrogeochemical studies and assessment of the sandstone – shale – […]
ABSTRACT The study examines the influence of wastewater on soil chemical in Kaduna South. Sixteen water and fifteen soil samples were collected in drains and on irrigated fields. The samples were subjected to laboratory analyses to determine properties related to sodicity, salinity and toxicity. The result of analyses has shown that soils in Kaduna South […]
ABSTRACT A total of 110 stream sediments samples were collected from streams in the eastern part of Oban Massif. The samples were analysed for Pb, Zn, Cu, Sn, Ta and U using atomic absorption spectrophotometer VGP system, model 210. The mean concentration for the elements were Pb (4.0), Zn (42.0), Cu (9.0), Sn (3.0), Ta […]
ABSTRACT Carbonate deposits are known to occur in three geologic settings in Cameroon including sedimentary, igneous and metamorphic terrains. These carbonates include limestones, dolomitic limestones, marl, marble, travertine and carbonatites. Sedimentary carbonate deposits outcrop in the Douala basin in the Mungo valley, Kompina and Logbajeck; in the Mamfe basin along the banks of the Manyu […]
ABSTRACT The prospects of phytoremediation of oil polluted sites in areas where is oil exploration, extraction and transport are evaluated in this study in relation to environmental degradation and public health. The study revealed that phytoremediation of oil polluted sites has some prospects and is likely to attract policy makers to enforce its application in […]
