ABSTRACT Solution growth technique was used to deposit thin films of Manganese Suphide (MnS), Calcium Sulphide (CaS), Magnesium Sulphide (MgS), Barium Sulphide (Bas), Zinc Fluoride (ZnFz) and Calcium Oxide (CaO) on micro-slides (Substrates) at different bath parameters which include temperature, molarity of solution, Volume of solution and water, time of d.eposition and pH. The absorbance, A was measured using spectrophotometer ranging from ultraviolet to visible regions. The Transmittance, T...
ABSTRACT Extracts and powders produced from the leaves of two indigenous vegetables – ‘atama’ (Heinsia crinata) and ‘uchakoro’ (Vitex doniana) were evaluated. Four groups of processes were applied on the vegetables to obtain the samples: blanching, oven drying and milling; oven drying and milling; steam blanching, wet-milling, filtration, and fermentation; fermentation, wet-milling and filtration. After, a preliminary study to evaluate the antinutritional factors at different interv...
ABSTRACT This study is concerned with the design of a Decision Support System for finding the Shortest path to a destination. The objectives of the study is to determine the optimal shortest/fastest path to a given destination or optimal shortest distance/fastest time to a given destination amongst others. The shortest path algorithm used is Dijkstra’s algorithm with finite nodes in the road network for optimum performance. Hence, the system developed in this study, seeks for an optimal sol...
ABSTRACT This research work presents findings of the extent and distributions of saline zone and the hydrochemical characteristics of the groundwater of Awe, Keana and Giza areas in the Middle Benue Trough of Nigeria.Staticwater levels(swl) of hand dug wells were measured andthe results used to generate hydraulic head data and hydraulichead map. The static water levels range from 1.0m to 13.5m at Awe, 1.0m to 4.5m at Keana and 2.2m to 9.2m at Giza. The hydraulic head maps for the three areas ...
ABSTRACT The role of water in petroleum migration has hitherto been grossly underplayed because of the unsuccessful search for a model that demonstrates the movement of water and hydrocarbons combined in a single phase, It appears, however, that many of the alternative mechanisms that have been favoured also require the availability and movement of large quantities of water at great depths for their efficiency. For example in models that favour continuous oil phase during migration, excessive...
ABSTRACT This research work is concerned with the detection, analysis and fixing of software bugs. The objective of this work was to identify software development process with a focus of identifying cost effective methods of developing and managing software systems by introducing a post-deployment debugging approach which helps track software’s stability and at same time serve as a software bug-data repository. To achieve this objective, a web-based application –BugTracker was developed t...
ABSTRACT Statistical, analytical and numerical methods have been used to develop a model for phenomenology and dynamical evolution of Compact Steep Spectrum (CSS) sources through the ambient medium of density, e n , within a characteristic time, T . Results show that the empirical relation between spectral turnover, n p , and D implies that 0.34 n p e ~ n , suggesting that the spectral turnover constitutes a characteristic signature of dense gases around CSS sources. However, since the charac...

ABSTRACT The rocks and soils underlying Lambata-Minna and Minna-Bida roads in central Nigeria were mapped with the view to determine their impact on the stability of the roads underlain by them. Vertical electrical sounding was done along the roads to determine the soil profile of the roads and statistics of the roads utilization was also done to infer if the roads are overused by vehicles. The geophysical studies revealed that the soil profiles of the two roads are composed of laterite, sand...
ABSTRACT Human Resource (HR) unit is a vital department in any institution of higher learning. The unit manages the staff welfare, recruits new staff and keep track of their records until retirement. The unit is also responsible for adequate dissemination of information through official memo and online communication to the entire stake holders of the institutions and beyond. The main objective of this study was to introduce a substantial improvement to the existing website that was been used ...
ABSTRACT The purpose of this work was to examine the patterns and determinants of fertility in Nsukka region, Enugu State, Nigeria. This was necessarily because most fertility studies across the nation lay emphasis on single or selected determinants, and using the findings to make recommendations on generalized terms which may not be applicable in different parts of the country. The data for this work was generated from questionnaire survey administered to 840 women of the reproductive age co...
Abstract CT scan is one of the most valuable tools used in the centers of modern health care and are accompanied by radiation dose greater than that of the normal radiographic and must be therefore use carefully to protect patients from radiation. The aim of this study to compare between radiation dose and image quality and to compare between CT brain protocols and radiation dose . Random samples consist of 30 patients who underwent CT brain examination. The patients data registered(age, gend...
ABSTRACT The Nanka Sand (~ocene, Ypresian Stage) is one of the several lithostratigraphic units comprising the lithic fill of the Anambra Basin, southeastern Nigeria. Its unitstratotype has been selected from a system of gullies in the Nanka town. Here the unit is 305 metres thick and is underlain by the Imo Shale and, farther southwest, overlain by the Ogwashi-Asaba Formation. The stratigraphic column may be divided into four cross-bedded and burrowed tabular sand subunits ranging from 50 to...
ABSTRACT We have modelled an open channel flow through a porous media (River). In the model, we considered water as an incompressible fluid; the flow as steady and uniform; the system is assumed to be isothermal and the flow, also a laminar flow. We have solved the resulting equation using analytical method. By some mathematical operations, the momentum partial differential equation (PDE) was reduced to ordinary differential equation (ODE) and the resulting equations are solved analytically u...
ABSTRACT The majority of software development organizations all over the world are small enterprises. Successful implementation of SPI methodologies in small software enterprises (SEs) is generally not possible because such organizations are not capable of investing the cost of implementing these programs and limited resources. Software Process Improvement (SPI) activities have been reported to result in remarkable improvements in the quality of software, reduced time to market and increased ...
