The water control goal for constructing Kubanni reservoir in 1973 is threatened by accumulation of sediments in it as a result of its design, anthropogenic activities on some parts of its catchments’ area and the highly erosive nature of the soil type in the basin. To improve on the effective management of the Kubanni Reservoir, sedimentation in ... Continue Reading
This research studied the Internet Protocol traffic on the Ahmadu Bello University Zaria network in order to develop a strategic Bandwidth Management model. This work used a packet sniffer on the network for the investigation of different types of Internet Protocol (IP) traffic in order to device a bandwidth management strategy that will be based o...

In this research work, the possibility of using hot bitumen as quenching medium for austempering of steel and ductile cast iron was investigated. Standard izod Impact, hardness and tensile samples were machined from 0.55%C-steel, 0.75%C-steel and ductile cast iron bars. The samples were austenitized at 800,850, 900 and 950oC, quenched in hot bitume... Continue Reading
Crucibles are manufactured from naturally occurring substance in the earth crust �“ clay, quartzite, chromate, bauxite, graphite etc. All these materials do not occur in their pure form, hence needs some form of treatment before their usage in manufacturing. In this study, the graphite from Bauchi State of Nigeria was beneficiated and characterize... Continue Reading
This study investigates the performance of laboratory pond system containing immobilized cells of Saccharomyces cerevisiae in the treatment of raw tannery wastewater as compared to a pond system without cells. The performance of the pond system was evaluated by the measurements of BOD, COD, sulphate, TS, chloride, pH, chromium and cadmium. Also, th... Continue Reading
This work was aimed at investigating the effect of earthworm (Eudrilus eugeniae) and organic amendments on the bioremediation of used engine oil contaminated soil, a process thought to be limited by mass transfer. The use of organic amendment alone facilitated bioremediation. The results obtained showed that the first order bioremediation kinetics ... Continue Reading
This work centers on the study of the electrical energy consumption pattern of Ahmadu Bello University Samaru Zaria over a period of five years to establish the present energy demand and to project future demand .To obtain the amount and pattern of electrical energy consumption, statistical data for five years were collected for PHCN supply and gen...

For several reasons, invisible electromagnetic signals in the RF and infrared frequency spectra are preferred for the remote control of consumer electronics. However, a niche exists for the use of visible light for the remote control of domestic electrical fittings which require simple power control operations. Electrical fitting controllers like l...

This thesis is on the study of Cellular Mobile Radio Signal Propagation Characteristics. Measurements of received signal powers were taken when the measuring device was moving outwards from some selected Base Stations along the Propagation paths, in outdoor environments (rural and urban). The variations of the signal in relation to distance away fr... Continue Reading
Virtually all activities of man is centered around conversion of energy from one form or type to another. From the basic functioning of human body mechanism to all practical activities of man starting from burning of wood to generate heat during stone age to latest satellite communication all involve energy transformation. The inter-convertibility ... Continue Reading
The preliminary investigation of the black cotton soil collected from New Marte, Borno State, shows that it belongs to A-7-6 (13) in AASHTO and CH in the Unified Soil Classification System (USCS), respectively. Soil under these groups are usually very poor for engineering use which was why it was treated with an ordinary Portland cement - locust be... Continue Reading
There is a defined level of ionizing radiation (effective dose of 50mSv in any single year) that radiation workers are allowed to be exposed to, according to the International Committee on Radiation Protection (I.C.R.P) proposal which is duly adopted by International Atomic Energy Agency. Gas detectors are commonly used for radiation monitoring bec... Continue Reading
The decreasing availability of fuel wood, coupled with the ever rising prices of kerosene and cooking gas in Nigeria draws attention to consider alternative sources of energy for domestic and cottage level industrial use in the country. This research work was conducted to design and construct a low cost briquette machine for rural communities in Ni... Continue Reading
A simple solar energy powered intermittent adsorption refrigeration system was designed, fabricated and tested. The system uses a Zeolite as the adsorberand water as the working fluid. The heat sourceis a parabolic trough concentratorwhich is to collect and concentrate solar thermal energy onto a black bodycoated copper absorber. The generator driv... Continue Reading
An outward radial flow reaction water turbine was designed based on Euler one-dimensional theory, constructed and tested to drive a 6W bicycle electric dynamo using water from supply mains. The turbine watered and lit the place it was tested eliminating the use of energy from other costlier sources which are not as environmental friendly. Available... Continue Reading
