A process route for the beneficiation of Mallam Ayuba Manganese deposit located in Kaduna State, Nigeria was developed. By this route a low grade manganese concentrate which can be used in the production of spiegeleisen using the blast furnace process was produced. Based on the chemical, size/assay and mineralogical analyses carried out in this stu... Continue Reading
A laboratory study was formulated to investigate the effect of spinning disc deterioration (damage of disc teeth and surface groove clogging) on the performance of ultra low volume sprayer. To do this, artificial teeth damages of varying degrees of severity were inflicted on three of five chosen identical spinning discs of 'Micron micro ulva' batte... Continue Reading
Drought is a creeping natural phenomenon affecting the arid and semi arid regions, including Nigerian Sudano-Sahelian Region. This research investigated droughts in Nigeria Sudano-Sahelian Region and developed forecasting models for drought monitoring and management in the region using well analysed meteorological data and imageries. The meteorolog... Continue Reading
This study was carried out to investigate the removal of chromium (VI) from chromate solution using deacetylated chitin extracted from mussel shell. Mussel shells were obtained from Gubi dam in Bauchi, Nigeria and chemical method was used to extract chitin and then chitosan from these shells. The mussel shell contained 15.14% chitosan as obtained f... Continue Reading
This investigative research consists of three parts: Plotting of theoretical propagation curves with the aid of computer, determining the effect of the variation of the ground conductivity on ground-wave field strength and deduction of the ground conductivity. Theoretical ground-wave propagation curves were plotted for flat earth with the aid of a ... Continue Reading
Inverted Pendulum phenomenon has been critical in the modeling and stabilization of space-ships, rockets, humanoid robots, etc and also in understanding classical control systems. This research is aimed at extending the modeling and complexity of the inverted pendulum from single-link or double-link to a multilink type, with particular emphasis on ... Continue Reading
Prior' if) 1919, borrow pits excavated into clay pans to collect and retain rainfall and local run-off served as a major water supply source to the settled Fulanis in the Wawa bush of the present Bauchi state, Nigeria. Attempts to make them a regular water supply source in lateryears failed mainly due to lack of maintenance. In the arid regions of ... Continue Reading
A field experiment was carried out from Feb-May 2012 at the irrigation Research Farm, Institute of Agricultural Research, Samaru, to determine the yield and water use response of watermelon under Deficit irrigation and mulch. The experiment consisted of four levels of irrigation water application depth of 100% (I100), 75% (I75), 50% (I50) and 25% (... Continue Reading
In this research work, structural grade properties of some selected Nigerian timber species namely: Chlorophoral excelsa (Iroko), Khaya senegalensis (Mahogany), Daniellia oliveri (Maje) and Ceiba pentandra (Araba) were carried out after classifying the species to international strength classification system using EN338 (2008) with the aid of statis...

Different lateritic deposits in and around Kaduna were investigated to determine the variations in the physical/ chemical compositions of the laterites. These variations in the physical/chemical compositions affect the mechanical properties of the laterites in the production of earthcrete blocks. Cylindrical specimens were cast to investigate the b... Continue Reading
The effects of electric power interruptions resulting from severe power outages were investigated and analyzed using five cold rooms as a case study. Two approaches have been developed and used. One is based on customers‘ survey that mainly investigates the preparatory actions that a customer may take to reduce the effect of outages. The other on... Continue Reading
The growing concern for environmental preservation and the search for new energy sources to replace the fossil fuels have received much attention over the last four decades. Photocatalysis is a promising solution to these challenges. It is therefore, pertinent to investigate local indigenous photocatalysts and to increase their efficiency under vis... Continue Reading
The potential of Pindiga bentonitic clay for phenol adsorption from aqueous solution and photocatalytic degradation was studied. Pindiga bentonic clay was treated with oxalic acid and calcined at a temperature of 1000oC and was successfully used as an adsorbent and for the degradation of phenol under visible light illumination. The processes were i... Continue Reading
This worked aimed at developing an optimal reconfiguration algorithm for a radial distribution network using fast and elitist non-dominated sorting genetic algorithm (NSGA II), considering distributed generation. The work models the reconfiguration using a pragmatic multi-objective approach considering active power loss and total voltage deviation,... Continue Reading
In this study the financial and economic feasibility of OnuakuRiver in Aku community of Abia state was evaluated using indicators like the Net Present value (NPV), Payback Period, Benefit cost ratio (BCR) and Internal Rate of Return (IRR) to ascertain the feasibility and viability of the project. Here the breakeven point of the project, profit, cas... Continue Reading
