Conventionally, air injection has been used for recovery of heavy crude oil in the production field, but studies have shown that depletion of light crude oil in the reservoir leads to abandonment of such wells. Hence, this work studied the kinetics and combustion of light crude oil in-situ the reservoir to understand their potentials for high-press... Continue Reading
The studies on oils in general have a significant role to play in the well being of mankind. In this research work, Moringa oleifera oil and castor oil were both extracted from their seeds using mechanical press method. Moringa oleifera oil and castor oil were blended in various proportions and used in preparing soap samples which were subsequently... Continue Reading
Engineers are often faced with the problem of constructing on black cotton soils, because of their unsuitable behaviour for construction.The preliminary investigation conducted on the natural black cotton soil collected fromDeba, Deba Local Government Area of Gombe State shows that it falls under A-7-6(16) AASHTO classification and CL according to ...

This research investigated the synergistic effects of Moringa oleifera seed cake extract and Opuntia stricta(cactus) mucilage in surface water purification. The synergistic effects of the two coagulants on turbidity, conductivity, total dissolved solid(TDS), pH, chemical oxygen demand (COD),biological oxygen demand (BOD) and bacteria (E.coli)were s...

The need to assess the heavy metals uptake by vegetables cultivated and irrigated with wastewater along the watercourse of a stream, have led to a controlled field experiments in Zaria Metropolis. Five heavy metals; Cadmium (Cd), Chromium (Cr), Lead (Pb), Manganese (Mn) and Zinc (Zn) were determined using the Atomic Absorption Spectrophotometer (AA... Continue Reading
This research work was centered on optimizing the Fluxgate Magnetometer Sensor (FMS)at reduced noise level and enhanced sensitivity. The FMS was developed using Manganese Zinc (MnZn) ferrite alloy different from the usual permalloy and amorphous alloy materials. The developed FMS using MnZn ferrite achieved reduced sensor dimensions with high sensi... Continue Reading
The performance of photovoltaic (PV) module is dependent on shading conditions of the cells. This research work is aimed at developing an improved PV-model considering the various degree of shading on PV-cells connected in a PV-module. This is based on modelling the different degrees of shading of cells in a module into the general model by introdu... Continue Reading
This research investigated image recognition frameworks on datasets of visible-light and infrared (IR) imagery using deep convolutional neural networks (CNN). This is due to their recent success on a variety of problems including computer vision which often surpassed the state of the art methods. Three deep learning based object recognition approac...

This study is aimed at the development of a mechanism for black hole attack mitigation in Wireless Sensor Network (WSN) using a modified Bacterial Foraging Optimization Algorithm (BFOA). A total of 200 randomly generated bacterial sensor nodes with a communication range of 20m were deployed in a 100mx100m network coverage area, consisting of four b... Continue Reading
Modern campus networks are designed for high-speed service with the capacity to handle many organization's bandwidth requirements, support data applications such as electronic-mail, web and files sharing services. These networks sometime lack the capacity to guarantee quality of service for voice, video and other interactive applications due to ban... Continue Reading
The Sokoto Basin,(the South-Eastern sectorof Iullemmeden basin), located in Nigeria, consists of an aquifer system which is bi-layered with cretaceous Continental Intercalaire (CI) sedimentary deposit at the bottom,(Sokoto Group, Rima Group, Gundumi-Illo Formation), by Continental Terminal (CT) Formation(Gwandu Formation) and surface water. The wat... Continue Reading
This study determined the effects of copper addition and section thickness on some mechanical properties and the morphology of graphite flakes in grey cast iron. It also characterised the microstructure of grey cast iron evolved in the investigation. This was of the view of ensuring that automotive industry designers are able to make informed choic...

This study is to investigate the effects of Expanded Polystyrene (EPS) as a partial replacement for coarse aggregates at 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50% at elevated temperatures of Room Temperature (280C), 200?, 400?, 600?, and 800? for the duration of 2 hrs each. Compressive strength and flexural strength were carried out o... Continue Reading
Single stage alkali-catalyzed transesterification of vegetable oils having free fatty acid (FFA) content above 0.5% promotes saponification which lowers the biodiesel yield by deactivating the catalyst. A strong solid base KF/Eggshell catalyst, which is capable of circumventing saponification while producing biodiesel in a single stage from neem oi... Continue Reading
The challenges of continual depletion, economic crisis and environmental issues of the petroleum fuels have attracted the scientists’ interest to seek for alternatives to fossil fuels.Biodiesel is the alternative to petrol diesel because; it has similar physicochemical properties to petrol diesel. However, biodiesel has not been competing favoura... Continue Reading
