ABSTRACT The thrust of the study which carried out in the Cenozoic Niger Delta is to infer and predict potential Petrophysical properties and hydrocarbon presence in unexplored areas proximal to producing areas in the eastern flank of Cenozoic Niger Delta, Nigeria, using seismic data and analogue proximal well data set from a producing area for subsurface reservoir characterization. Seismic and offset well dataset were used as input dataset to carry out Petrophysical evaluation, Seismic int...
ABSTRACT Interpretation of structures and reservoir characterization using 3D seismic cube and well data pose great challenges in mapping because of their complexities especially in structural deformations, and where identification of reservoir facies is a major challenge to plan delineation, field appraisal and development drilling. Thus, the project work takes a model approach. The ―DIBA‖ Field in the Niger Delta contains hydrocarbons that are largely trapped in sandstones and unconsol...
ABSTRACT Diabetes mellitus, is a metabolic disorder caused by the inability of the beta pancreatic cells to adequately produce insulin or due to insulin resistance of cells. As a result of the increasingly high incidence of diabetes globally, the World Health Organization (WHO) has set timelines and guidelines for the reduction of the risk of mortalities and morbidities associated with noncommunicable diseases including diabetes, by the year 2030. However, this agenda is hinged on the avai...
ABSTRACT An integrated seismic interpretation using 3-D seismic data, check shot data and a suite of well logs for four wells were analyzed with the Petrel (seismic to simulation software). The objectives were to carry out a detailed formation evaluation, reservoir characterisation and a 3-D assisted structural interpretation of the densely faulted oil field in the coastal depo-belt of the Niger Delta. RMS amplitude, instantaneous frequency map and interval average extraction maps were ext...
This project is concerned with the development and evaluation of an atom trapping technique for determination of heavy metals in environmental samples. Modified atom-trapping technique using fabricated nickel tube/sample holder (crucible) was employed to increase the sensitivity of a flame atomic absorption spectrometry.MBasic performance data for different parameters, such as burner height and the height of the support, were studied. Different designs and ways of placing the atom trap ov...
ABSTRACT There has been an increase in the occurrence of antibiotic resistance among Salmonella enterica, one of the commonest causative agents of Salmonella infections. Fluoroquinolones and third generation cephalosporins are usually the drugs of choice in the management of Salmonella infections. Previous reports have indicated common occurrence of multi-drug resistance (MDR) including resistance to β-lactams and fluoroquinolones among clinical Gram-negative organisms. However, there is pa...
ABSTRACT Luminescence sensitisation is an important stage in the application of quartz in predose retrospective dosimetry and dating. The existing techniques for sensitisation in quartz are Pre-Exposure Dose (PED) and Thermal Activation (TA). Previous works were centred on combined actions of PED and TA with less attention given to the separate contributions of these techniques in pre-dose sensitisation of quartz. This work was undertaken to determine the separate contributions of PED and TA...
ABSTRACT Background & objectives: Investigations were conducted to obtain key entomological indices of Anopheles gambiae s.l. at Igbo-Ora, a rural community in south-west Nigeria. Methods: Mosquitoes were caught daily for a week from rooms where tenants had slept the previous night in each of the four months June, July (2001), and August, September (2002). Anopheles gambiae s.l. sibling species were PCR-identified, the blood meal origin was determined by direct ELISA, and the circumsporozoit...

ABSTRACT Exposure to certain hexavalent chromate compounds (HCC) causes lung and colon cancers. Their mechanisms of cytotoxicity are unclear, but believed to be affected by ascorbate and particle size. However, their role is not clearly defined. Co-exposure with sodium arsenite (SA) is common, but its effect on HCC toxicity is unknown. Current therapy has side effects, necessitating the search for antidote from unexplored natural products such as Rauvolfia vomitora (RV). This study therefore...
ABSTRACT The Albumin Blue 580 fluorescent dye was evaluated for the measurement of urine albumin content. The calibration of the assay was linear up to 150.0mg/L with a minimum detection limit of 1.4mg/L. The intraassay CV was 4.3%(14.5mg/L), 3.7%(50.2mg/L) and 1.4%(100.0mg/L), interassay CV was 2.7%, 2.6% and 3.7% for the respective urine albumin concentrations. Recovery of added albumin to urine was 95-112%, reproducibility for 9 replicate analysis of 3 urine samples was 8.2%(6.0mg/L), 4.6%...
ABSTRACT This work considered the unsteady state drainage of fluid from a vertical column of porous material of varying porosities in an attempt to verify 'variation of drawn dawn surface with porosity and time using riverbed sand. Kerosene was used as the flowing fluid: Mathematical assumptions ware made in connection with Ducy's law.
ABSTRACT Little is known about dolphins present in Ghanaian coastal waters. Taxonomic status, catch rate, and impact of the fishery on these animals, are areas, which have remained virtually untouched by previous workers. The present study attempts to fill-in these gaps in knowledge. Studies conducted during 1998 -2000 revealed the presence of the following eight species in Ghanaian waters: Stenella clymene, Stenella attenuata, Steno bredanensis, Tursiops truncatus, Grampus griseus, Lagenodel...
ABSTRACT Available information on medicinal plants indicates habitat loss and has heightened the need for more proactive conservation strategies. Conservation efforts in this direction resulted in an ecopharmacological survey in the West African sub-region by three countries (Nigeria, Ghana and Republic of Benin) to assess frequently used medicinal plants. The result of the socio-economic study based on utilization pattern regionally was used to produce a list of ten topmost frequently used a...
ABSTRACT Experimental investigations have shown that variation of porosity and hydraulic gradient are responsible for the deviations from Darcy's law, which is perfectly obeyed only when the fluid flow is laminar in porous media. Previous attempts to modify this equation considered only the effects of porosity of surface-active materials such as clay in causing deviations from Darcy's law. In this study, both the effect of porosity of any porous medium and hydraulic gradient from recent exper...
