Abstract The corrosion inhibition of aluminium and mild steel in H2SO4 in the presence of Bromothymol blue, BTB, Dimethyl yellow, DMY, Methyl orange, MO, Titanium (IV) oxide, TO and Cassia Siamea Lam, CSL leaves extract at 303 – 313K was studied using “Absorbance difference” technique. The results showed that inhibition efficiency (%IE) increased with increase in inhibitor concentration (except for BTB, where beyond a “critical” concentration of 0.0007M, it reversed its function and...

Cultivation of Jatropha curcas L. for production of biodiesel as an alternative source of energy is crucial for sustainable development in Nigeria. Pests and pathogens especially fungi have been reported to be a major constraint to commercial cultivation of J. curcas in Asia and some West African countries. However, this is yet to be fully investigated and documented in Nigeria. Fungal pathogens infecting J. curcas in southwestern Nigeria were therefore investigated. Two hundred plant s...
ABSTRACT The aim of this project is to develop an online hotel reservation system, a case study of FORT ELLIS Hotels LTD Gwagwalada, Abuj a which corrects the inefficiency of the current existing manual system, where all bookings and reservations and other management activities are done manually. For improving hotel business and providing scope for global reservation of rooms we developed an online hotel reservation system which is a web application. The major programming language that was us...
ABSTRACT This project is insight into the design and implementation of an Online Counseling System. The primary aim of this project is to eradicate the long queues at the counseling unit. It was discovered in the course of this study that students or counselees have neglected the face-to-face counseling mode which is been offered by the university because of the stress in registering for counseling and seeing the counselor, so the need for a better system came about with online counseling sys...
ABSTRACT Automatic Offiine Isolated handwriting word verification system using template matching (pixel by pixel matching) is proposed in the research work. The composition of 400 word essay, the handwritten biometrics of 50 people (students); 25 males and 25 females to handwrite the essay five times in separate sheet of papers the aim here is to verify if a particular handwriting is from that same person or is a fake. No speclfzcation for pen type and color were given. The collected document...
ABSTRACT The microbial and chemical compositions of some indigenous foods of Southeastern Nigeria (Imo and Anambra States) were investigated. The total aerobic plate count (TAPC) for Ogiri ranged from 1.2 x 1010 to 2.4 x1011 cfu/g, the coliform count ranged from 2.1 x101 to 9.8 x102 cfu/g, and fungal count ranged from 1.0x108 to 3.3x1011 cfu/g. Aniga had a mean TAPC of 1.4x1011 cfu/g, coliform count of 3.8 x101 cfu/g and fungal count of 1.9x1011 cfu/g. Agbarati had a TAPC ranged from 1.1x109 ...
ABSTRACT The industrialization of our society, including drilling for oil, mining of coal and minerals has led to increasing production of xenobiotic and natural chemical substances. Continual releases of polycyclic aromatic hydrocarbons (PAHs) from mining and drilling activities leads to their deposition in coastal environments and ultimately bioaccumulation in plants and animals, creating the danger of toxicity. PAH are deemed to be carcinogenic, mutagenic and teratogenic. In Ghana, oil dri...
ABSTRACT Port Harcourt and Omoku are two densely populated towns in Rivers State. This may not be unconnected with the presence of such attractive features as tertiary institutions, oil and gas companies, very large daily markets, free electric power supply (as in Omoku) among others. In the light of the above, it is expected that industrial effluents, domestic waste discharge, automobile emissions, gas flaring etc generate atmospheric aerosols which dissolve to form particulates as pollutan...
ABSTRACT The levels of Cd, Cu, Ni, Pb and Zn in soils of municipal solid waste and ground water within the Abuja municipality was determined. The flame atomic absorption spectrophotometry was used to determine the metals. The aqua reqia extraction method was used to extract metals from the soils. The average concentration of metals in the soil samples were Cd = 4.3 J..Lgg-1 dry weight (2.4-5.9 J..Lgg-1 dry weight), Cu = 12.4 J.!gg-1 dry weight (3.4 - 19.9 J.!gg-1 dry weight) Ni = 8.3J..Lgg-1...
ABSTRACT The asset price returns are multi-period (that is multi-fractal dimensional) market depending on market scenarios which are the measure points. In this research work, a number of continuous time stochastic models were formulated, for the measurement of random behaviour of equity returns, using multi-fractal measures which examine power law behaviours at different time scales. Fractal exponent was first derived followed by a seemingly Black-Scholes parabolic equation. The solution to...
Abstract The present recession of the Lower River Benue has led to some adverse ecological changes and the decline of agricultural production in the face of rapid population growth in the area. The solution to the problem certainly requires a detailed agricultural land use analysis. The existing agricultural systems in the Lower River Benue Basin were identified and analyzed in order to determine their characteristics and spatial trends as a basis for conscious agricultural planning and inte...
ABSTRACT Used crankcase oil is disposed off indiscriminately and it eventually finds its way into the aquatic environment resulting in surface and ground water contamination by complex interacting chemicals and substances. Polycyclic aromatic hydrocarbons (PAHs), heavy metals, additives, antioxidants and trace levels of chlorinated solvents have been detected in used engine oil and these pose a great risk to fish populations and the human consumer of fish. This study (i) investigated the sub...
ABSTRACT User satisfaction is one of the key research area of Information Technology (IT) particularly, Information System (IS). It is recognized by many researchers as a significant factor in determining IS success. In view of it competitive advantage, most business organizations nowadays focus on IS as a means of minimizing cost and maximizing profit. Unfortunately, many are not getting the expected outcomes as agreed in the IS requirements, not because of wrong choice of products and vend...
ABSTRACT Background Acute febrile illness (AFI) is responsible for a significant number of childhood mortality and morbidity and remains a common clinical presentation at most hospitals. Lack of appropriate screening techniques present a challenge in identifying potential pathogens associated with AFI. This study investigated the microbial etiology of AFI among febrile children, evaluated the potential use of inflammatory mediators as biomarkers of fever, and developed a web-based model to pr...
