This study is an investigation into the effect of elapsed time after mixing on the properties of modified laterite. The modifiers used are portland cement and hydrated lime. The laterite was modified with 1, 2 and 3 percent of portland cement and hydrated lime. The elapsed time used for this study ranges from 0 to 3hours, with tests conducted at 1.... Continue Reading
The assessment of dumpsite impact on soil and groundwater quality in Tudun Wada, Kaduna was carried out. Eight samples of soil and groundwater respectively were collected using grid sampling method and analysed by using Atomic Absorption spectrometer, colony counter, data logging spectrometer and oxygen meter, in Kaduna State Environmental Protecti...

In a bid to address environmental challenges associated with the management of waste Coca cola glass bottle, this study sets out to develop glass ceramic materials using waste Coca cola glass bottles. Magnesite from Sakatsimta in Adamawa state and reagent grade chrome (coloring agent) were used to modify the composition of the coca cola glass bottl... Continue Reading
Water tanks are liquid storage containers that store water for human consumption. They are usually made of polyethylene (plastic), steel, clay, ceramics and fiber glass. The need to investigate thechanges in water quality during storage in different types of water storage tanks or vessels is very crucial in establishing which tank contributes to de...

Geothermal energy is thought to ... Continue Reading
The aim of this study is to develop and analytically compare Quotients Regression based empirical models with artificial neural network (ANN) based models for path loss prediction. The terrains considered as case study include i) the rural terrain between Jos and Abuja ii) the Urban terrain (Abuja), and iii) the semi-urban terrain (Maiduguri). The ... Continue Reading
The physical presence of the oil industry in Nigeria is so large and has resulted in a lot of activities in the upstream sector which has deleterious effects on ecosystem stability and local biodiversity �“ which the peoples‘ livelihoods depend upon. This research provides an overview of environmental issues in the oil and gas industry in Nigeri... Continue Reading
Nigeria experiences the highest rate of road traffic accidents resulting in fatalities and various levels of injuries. On Abuja-Lokoja road, traffic accident takes the lion’s share of the risk having highest number of vehicular accidents withcorresponding fatalities and injurieswhich has a great impact on cost and the socio-economic development o...

In this study, three vegetable cutting fluid namely: Tiger nut, water melon seed and neem seed were selected in drilling operation of mild steel using High Speed Steel (HSS) cutting tool at varying spindle speeds, feed rate and constant depth of cut. A commercially available convectional mineral oil was used as standard for comparative analysis. Fl... Continue Reading
Studies showed that the use of an automated incubator powered from the mains electricity, a solar powered incubator or the kerosene type incubator for the production of day-old chicks is either very expensive to manage or ineffective in operation. Hence, this research work is aimed at designing, fabrication and testing of an automated incubator pow... Continue Reading
This research study the rate of energy dissipation losses taking place in various types of stepped spillway geometries (end sill at all steps, inclined at all steps, inclined between two steps, end sill between two steps, combination of inclined and end sill on the stepped spillway starting with end sill and combination of inclined and end sill on ...

In this dissertation we developed a fiber optic connector optical return loss (ORL) model from the connector endface image profile of a 200X inspection microscope. The connector endface profiles were histogram equalized and then evaluated with the Canny, Sobel, Prewitt, Laplacian of the Gaussian (LoG), Roberts and Frei-Chen edge detection operators...
