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...
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...
Chapter oneIntroduction1.1 Background of the StudyIn the advanced world like China, Britain, Australia and the United State ofAmerica, ticketing system are usually automated with the use of internet and e-commerce. Smart cards are usually used to make payment and ticket generatedafter. The use of electronic ticketing system has increasingly helped to address theproblem of long queue and time wastage problem. (Watts, 2012).An electronic ticketing system is a computerized system that is designe...
ABSTRACT This study was carried out to investigate the characterization and utilization of guava flavour concentrate produced from two guava cultivar using simple distillation technique for the flavor extraction. The physical properties of the flavor concentrate were determined and then utilized in the formulation of guava drinks with three different clouding agents (gum Arabic, garri aliquot and cheese-whey). The guava drink samples were also evaluated for different quality attributes whic...
ABSTRACT Endophytic microorganisms have proven to be potential sources of antimicrobials against recalcitrant pathogens. Extracts of an endophytic fungus, Emericella nidulans exhibited antibacterial activity against selected pathogens. Emericella nidulans was cultivated in broth and fermented at 28 ± 2°C for 7days and 21 days to obtain bioactive components. Solvents extraction of bioactive compounds from Emericella nidulans in the order of their polarity – n-Hexane, et...
Abstract The advent of Global Navigation Satellite Systems (GNSS) in space technology has tremendously improved the methods of positioning and navigation. Countries are now adopting the continuous observation and measurements using a network of GNSS receivers called Continuously Operating Reference Stations (CORS) as the standard. Hence, the study explore the CORS network in South West Nigeria and carry out site suitability analysis of the potential locations considered suitable for the insta...
Prevalence of Staphylococcus aureus and Escherichia coli from the surface of cockroaches found in the university of Lagos
ABSTRACT The experiment was carried out to investigate the effect of cement dust pollution onAmaranthus viridis in respect to growth, heavy metal uptake and the plant in general. Loamysoil was polluted with Dangote cement in a ratio of (100:1). It was observed that the presenceof cement dust in the polluted soil did not affect the germination time of the plant. Upongrowing the Amaranthus plant were polluted with 10.2gcement dust at 3datys in...
ABSTRACT Evidences have implicated free radicals or reactive oxygen species in mercuric chloride-induced nephrotoxicity. Diphenyl diselenide (PhSe)2, a simple and stable organoselenium compound, has been proposed as a good candidate for pharmacological and therapeutic purposes. This particular study was designed to investigate the protective effect of (PhSe)2 against mercuric chloride-induced nephrotoxicity. In this study, 44 female Wistar rats with weights ranging from 125g and 180g were...
Activation of caspase 3&9 by methanol extract of Gloriosa superba ABSTRACT Mitochondrion is the key regulator in cellular energy homeostasis and plays a central role in determining cell apoptotic process; it is therefore regarded as a vital target for cancer chemotherapy. Cancer is obviously one of the most common areas where demand for alternative treatment is overwhelming. Many investigations revealed that bioactive compounds in natural products can act on mitochondria to trigger the per...
Methanol extract of Gloriosa superba in this research was adopted due to the presence of photochemicals present in the plant. This photochemicals are known to act as antioxidants and anti tumor agent but it is not yet known if the activity of the plant is through the mitochondria mediated pathway, caspase activation and induction of apoptosis where up regulation is necessary
