Tapinanthus dodoneifolius belongs to the family Loranthaceae and is widely distributed in West Africa, Europe and Asia, commonly known as mistletoe. It exhibits a wide array of pharmacological activities including antimalarial, anticonvulsant, anti- microbial, and is effective in the relief of menstrual and stomach pain. Lupeol, a pentacyclic triterpenoid was isolated for the first time from the methanol leaf extract of Tapinanthus dodoneifolius and characterized by spectral analysis. Th...

Abstract Disruption of electrolyte, redox and neurochemical homeostasis alongside cellular energy crisis is a hallmark of cerebral ischaemia and reperfusion injury. This study investigated the effect of kolaviron (KV) on cortical and striatal cation imbalance, oxidative stress and neurochemical disturbances as well as neurobehavioural deficits in animals subjected to bilateral common carotid artery occlusion (BCCAO)-induced ischaemia/reperfusion injury. KV was administered at a dose of 100...
ABSTRACT In this project (A Multi-Wavelength View of M17 Massive Star-Forming Region), efforts were made to determine the distributions of polycyclic aromatic hydrocarbons (PAHs) within the M17 region. We find that PAHs are destroyed over a short distance or edge of the HII region. This PAH destruction edge can be located easily using Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) band-ratio images. We try to find out the relative roles of extreme ultraviolet (EUV) and...
ABSTRACT Libraries have been an important part of educational and information sector of any school. The success of any library largely depends on proper management. Several libraries have suffered failure as a result of inadequate management and incapacitations in handling sensitive information as regards members of the library. This research therefore, aimed at developing a digital library system, which will help direct and position library to meets its ever increasing demands. In the...
ABSTRACT This study was carried to with the aim of determining the antibacterial effect of Calotropis procera against some bacteria isolated spoilt nunu. Bacteria isolated from spoilt nunu were identified based on their Gram characteristics, morphology and biochemical characteristics. Calotropis procera was extracted using ethanol, methanol and distilled water. The ethanol and methanol extracts showed the presence of Saponins, Steroids, Terpenoids, Flavonoids, Tannins, Alkaloids, and Cardiac ...
Room temperature tribocorrosion behaviour of Al-4.5%Cu/SiC particulate composite was evaluated against stainless steel ball in natural sea water. Ab-initio, the Al-4.5%Cu was reinforced with 5,10,15 and 20 % SiC reinforcements to produce the Al-4.5%Cu/SiC particulate composite by stir casting method. The tribocorrosion test was carried out with an Anton Paar Tribometer at applied loads of...
ABSTRACT This project report is the result of the work done at Ipole area, Sikonge District from July to September 2008. The main objectives of this project was to identify the rock types present at Ipole area using rock magnetic properties and to determine the presence of Diamondiferous Kimberlite in Ipole lithologies.The following methods were used to accomplish the task; Heavy Mineral Sampling in Streams sediments, Loam and Auger sampling, Airborne magnetic survey, Geographic Information S...
Abstract - The purpose of the study is to examine the determinants of information security awareness (ISA) among employees of Capital Market Registrars (CMRs) in Lagos, Nigeria based on established factors from the existing literatures on ISA. The main objectives of the study are; to determine the level of information security awareness among CMRs’ employees and to identify the components that influence information security awareness. This study utilised a survey design. Stratified random s...
In this academic term paper, the industrial minerals in Nigeria were evaluated. The economic potentials were determined. Also, the level of the development and the industrial uses of these minerals were evaluated. It will interest you to know that Nigeria has over 30 industrial minerals. These minerals are dispersed in all regions of the country.
Background: Resistance to extended-spectrum cephalosporins among Enterobacteriaceae has been reported yet they serve as the last line treatment for severe infections in Uganda and other countries. This resistance often leads to nosocomial infection outbreaks and therapeutic failures from multidrug resistant bacteria. The main objective of this study was to determine the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in clinical samples of patients in variou...
Sorption properties of hydrolyzed starch graft poly (acrylic acid) and starch graft poly(acrylonitrile) copolymers as sorbents for the removal of Cd (II) and Cu(II) ions from aqueous solution in batch process were assessed. The copolymers were prepared using methods as reported in literature and were characterized in terms of morphology using scanning electron microscopy, confirmation of sorbents produced using Fourier transform infrared spectroscopy and thermal stability using thermogravimet...
The effects of the application of the graft copolymers (Hydrolyzed starch-g-polyacrylonitrile (HSPAN) and Hydrolyzed starch-g-polyacrylic acid (HSPAA)) on the nitrogen (N) and phosphorus (P) retention capacity of soil was evaluated in this study. Soil nutrient (N and P) retention capacity tests was carried out at three graft copolymers application rates (3.0, 6.0, and 9.0g/kg soil) against a blank soil sample to which graft copolymers was not applied. Diammonium phosphate (DAP) at 0, 100, and...
The competitive sorption of Cu (II), Pb (II) and Cd (II) by graft copolymer of cassava starch and acrylic acid was investigated using the response surface methodology. Optimization of the medium conditions was studied through experimental design. Response surface methodology including central composite design was successfully applied to develop a response surface to optimize the medium conditions. The most influential medium parameters were determined as initial concentration, contact time an...
Hydrolyzed starch graft poly (acrylic acid) and starch graft poly(acrylonitrile) copolymers were used as a sorbents for the removal of Pb(II) from aqueous solution in batch process. The sorbents were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and thermogravimetric analysis. The effect of contact time, initial concentration and temperature were assessed to optimize the conditions for maximum sorption of the metal ions. The experimental data were anal...
