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...
Hydrolyzed starch graft copolymers of acrylic acid and acrylonitrile were used as a sorbents for the competitive removal of Pb (II), Cd (II) and Cu (II) ions from aqueous solution in batch process. The sorbents were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, wide-angle x-ray diffractometer and thermogravimetric analysis. The equilibrium sorption properties were assessed to optimize the conditions for maximum competitive sorption of the metal ions. ...
The mechanical properties of snail shell reinforced unsaturated polyester composite was assessed in this study. Ground snail shells of particle size 65μm were introduced at different percentages into the unsaturated polyester resin. The powdered shells were characterized using FTIR to determine the functional groups present. The tensile test was performed using an Instron universal testing machine operated at a cross head speed of 10mm/min. The tensile test specimen preparation and testing p...
There is a growing interest in the research community of the possibility of reducing or total elimination of zinc oxide (ZnO) as activator in rubber compounds. This study therefore is an attempt in that direction to study the effect of polyethylene glycol (PEG) as an alternative activator in rubber compounds. Various levels of polyethylene glycol (0,2,3,4,5,6 phr) and zinc oxide (as reference) were compounded with 100phr of natural rubber and other compounding additives. The effects of both p...
ABSTRACTNew interactive computing applications are continually being developed in a bidto support people’s changing work and recreational activities. As research focuses on oneparticular class of interactive systems, high level models of interaction are formulated andrequirements emerge that reflect shared features or common functionality among those systems.Within this seminar a new class of interactive syst...
An automated event management system that works on all platforms/ Abstract Event management system is used to manage all the activity related to event. Inany event many service providers work simultaneously and it is very hard tomanage these providers. It is also important for event organizer that he has allthe contacts details of these service providers so that he can contact them anytime to plan an event at given time. This research work is todesign and implement a Multi-pla...
