ABSTRACT Wave velocities in sand stones are greatly influenced by porosity and clay contents.
ABSTRACT Background: Malaria co-infection with schistosomiasis is known to modulate the immune response and thereby to potentially alter the pathophysiological and immunological profile of the diseases.
ABSTRACT Merozoite surface protein-119 (MSP-119) specific antibodies which include processing inhibitory, blocking and neutral antibodies have been identified in individuals exposed to Plasmodium falciparum. Here we intend to look at the effect of single andmultiple amino acid substitutions ofMSP-119 on the recognition by polyclonal antibodies from children living in Igbo-Ora, Nigeria. This would provide us with information on the possibility of eliciting mainly processing inhibitory antibodi...
ABSTRACT During studies on the epidemiology of malaria at a rural community, Igbo-Ora, Southwest Nigeria, genotyping of Plasmodium falciparum extracted from infective Anopheles gambiae s.l. was undertaken. Circumsporozoite (CSP) ELISA was used on crushes from head-thorax for DNA extraction and PCR amplification for the determination of P. falciparum genotypes on merozoite surface protein-I and 2 (MSP-I & 2). Of the 65 infective anophelines, P. falciparum genotypes were positively identified i...
ABSTRACT Among the major lithostratigrahic units making up the Bida Basin are the lokoja and Patti formation overlain by the Agbaja Ironstone.
ABSTRACT Fault diagnosis, isolation and restoration from failure are crucial for maintenance and reliability of equipment.
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 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 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...
Abstract This research study focus on the determination of anti-nutritional content status of the uninfested and infested dried cassava chips by Prostephanus truncatus. Prostephanus truncatus, the larger grain borer, is an alien invasive post harvest pest; with wide spread population all over cassava growing regions. After an infestation period of 10 weeks in the laboratory, proximate analysis revealed increased values for only alkaloids content in the infested dried cassava chips, while all...
ABSTRACT The Agbowo-Orogun area of Ibadan, which is within the basement complex of southwestern Nigeria, is underlained by banded gneiss of the migmatites-gneiss complex. A total of thirty-five water sample?., made up of thirty-two from groundwater and three from surface water, were analyzed for their physico-chemical characteristics with the aim of assessing their quality and usability.
Abstract The boinsecticidal potency of three botanicals, namely: Allium sativum (Garlic), Allium cepa (Onion) and Capsicum annum (Red pepper) were tested on Oryzaephilus surinamensis (Saw- toothed grain beetle) infested with Phoenix dactylifera (Date fruits) at exposure periods of three weeks and six weeks in the Department of Zoology, Entomology Laboratory. The boinsecticides used were in powdered and whole forms at three different concentrations of 1.25g, 2.50g and 5.00g. Potency was deter...
ABSTRACT Roasted plantain (boli) is a delicacy in Nigeria. The conventional method of processing this food is crude, stressful and unhygienic In this work, an electric roaster capable of roasting twenty-one plantain fingers per batch was designed, fabricated and tested.
Human Ureaplasma had one species known as Ureaplasma urealyticum but was recently seperated into 2 species
