In this work, the possibility of upgrading a locally available low grade Manganese Ore was attempted. The low grade ore deposit is located in Wasagu/Danko Local Government Area of Kebbi State, North Western Nigeria. The work involved chemical and mineralogical characterization of the ore and separation tests using gravity and magnetic Separation Te... Continue Reading
This project is aimed at designing, constructing and testing of a single axis, variable speed passive solar tracking device. This is because all the solar trackers in use in the country are mainly imported. The design works on the principle that Freon �“ 12 (Dichloroflouromethane) boils at very low temperatures i.e. somewhat lower than �“ 300 F (... Continue Reading
This study investigated the destructive distillation of polyethylene based waste materials and Ahmadu Bello University Consultancy Services (ABUCONS) pure water sachets were used as the source for the waste polyethylene. This work involved carrying out destructive distillation on polyethylene waste with and without catalysts and monitoring the impr... Continue Reading
Fuzzy Time Series (FTS) forecasting technique is the amalgamation of fuzzy logic and time series technique. The critical issue in FTS forecasting is the determination of the interval length. This paper therefore, is a research on the effect of varying interval length and model basis on electric load forecasting using Fuzzy Time Series Model. The me... Continue Reading
The effects of organic resins (Methylene blue and Neutral red) and plant extracts (piliostigma thonningii and Gmelina arborea) on corrosion rate of medium carbon steel in 0.2M H2SO4 acid pickling solution were studied with a view to comparing them with a known standard inhibitor (Sodium Benzoate). Gravimetric and Gasometric measurements were carrie... Continue Reading
This study analysed the marketing system of artisanal fish in Kebbi State with the aim to determine characteristics of the market actors; structure, conduct and performance of the marketing system; profitability of fish processing enterprises and also the constraints associated with the marketing system. The data for the study were collected from b... Continue Reading
Unlike the common use of only ‘rainfall amounts’ in indexing the drought in a place, this study have identified, verified and validated the potentials of nine (9) other precipitation effectiveness variables (PEV) that can equally reflect the drought conditions in any place. The 10 PEVs have been effectively combined to derive a ‘at-site’ op... Continue Reading
This study is concerned with the analysis of signal strength and loss pattern of IEEE 802.11 wireless LANs. The efforts of which involved Electromagnetic Compatibility (EMC) assessment of the various access points (APs) operating in both 2.4GHz and 5GHz Frequencies from the Ahmadu Bello University Zaria, Wireless Network, at varied locations and ti...

The enzymatic hydrolysis of cassava starch to glucose has been studied. Aspergillus niger was isolated from deteriorated groundnut seeds and used as the amylase producer source. The effect of various process variables such as culture age, mycelia mass loading, pH, temperature and substrate (cassava starch) concentration were investigated in order t... Continue Reading
The effect of Vanadium and Molybdenum addition on the mechanical properties of ductile cast iron has been investigated. Alloys of ductile cast iron samples of varying additions of Vanadium and Molybdenum from 0.1- 0.3% were produced into cylindrical test bars by sand casting process using “sandwiched” treatment method. Unalloyed ductile cast ir... Continue Reading
Simultaneous Saccharification and Fermentation (SSF) were carried out to produce ethanol from maize stalk in 500ml conical flask. Aspergillus niger strains were isolated from four difference sources, maize stalk, soil, bambaranut, rotten wood. Cellulose degrading ability was screened by zone of clearance carried out by simple agar method.. Apergill... Continue Reading
The effects of variation of the intercritical annealing (ICA) temperature and time on the microstructural and mechanical property behaviours of high martensite dual phase (HMDP) steel have been investigated by intermediate quenching of microalloyed steel. The treatment consisted of initial austenitization and rapid quenching of the steel samples to... Continue Reading
To achieve high productivity, the blast furnace requires high quality coke. The coking properties of coke are directly related to the coke rate. The higher the coking properties, the lower the cost per tone of hot metal (pig iron) produced. Analysis of available data on Nigeria coals indicates that Lafia coal is slightly coking. In order to enhance... Continue Reading
The effect of austentitizing temperature and quenching medium on ductile cast iron in the as-quenched, cold treated and tempered condition was investigated. The study was based mainly on hardness and impact tests. Ductile cast iron speciemens were first given a normalizing beat treatment before quenching. Normalized specimens were heated to five au...
