Effects Of Clay Content And Porosity On Wave Velocities In Unconsolidated Media Wing Empirical Relations

ABSTRACT Wave velocities in sand stones are greatly influenced by porosity and clay contents.

Subtle Morbidities Associated With Malaria Co-Infection With Schistosomiasis Among Children In South-West Nigeria.

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. 

Antibody Specificities Of Children Living In A Malaria Endemic Area To Inhibitory And Blocking Epitopes On MSP-119 Of Plasmodium Falciparum

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...

Genetic Variants Of Plasmodium Falciparum In Infective Anopheles Gambiae S.L. At A Rural Community In Southwest Nigeria

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...

Aspects Of Hydrocarbon Potential And Clay Mineralogy Of The Patti Formulation, Southern Bida Basin, Nigeria

ABSTRACT Among the major lithostratigrahic units making up the Bida Basin are the lokoja and Patti formation overlain by the Agbaja Ironstone.

Diagnosis Of Gasoline-Fuelled Engine Exhaust Fume Related Faults Using Electronic Nose

ABSTRACT Fault diagnosis, isolation and restoration from failure are crucial for maintenance and reliability of equipment.

Entomological Indices Of Anopheles Gambiae Sensu Lato At A Rural Community In South-West Nigeria

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...

Effect Of Porosity On Surface Of Drawdown In An Unsteady State Drainage In Porous Material

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.

Management Of Indigenous Medicinal Plants In Nigeria Using Phenological Information

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...

Modification Of Fluid Flow Equation In Saturated Porous Media

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...

Anti-Nutritional Status Of Uninfested And Prostephanus Truncatus (Horn) (Coleptra: Bostichidae) Infested Dried Cassava Chips

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...

Hydogeochemical Assessment Of Surface Water And Ground Water Quality In Agbowo-Orogun Area Of Ibadan, Southwestern Nigeria

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. 

Application Of Selected Bioinsecticides In Management Of Oryzaephilus Surinamensis (Coleoptera: Silvaridae) On Phoenix Dactylifera (Date Fruits)

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...

Design, Fabrication and Evaluation of a Plantain Roaster

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.
