The rate of increase in multimedia data necessitated the need for a large number of storage devices. Nonetheless, the stored multimedia data has a lot of redundant video frames. These redundant frames make video browsing and retrieval difficult as well as time-consuming for the user; hence, negatively affecting bandwidth utilization and storage cap... Continue Reading
The new developments in mechanical engineering in Nigeria (Low Cost Vehicle project, aviation projects - AIR BEETLE, etc.), require in-house practical calculation techniques in design generally and calculation of stresses in machine components, particularly. The machine components (Spur Gears) under operation are subjected to stresses which differ ... Continue Reading
For reliable and efficient operation of power system, voltage level and reactive power flow along transmission lines has to be adequately regulated. To control reactive power flow over transmission lines and compensate for varying voltage drops, tap changing transformers are required. By altering the voltage magnitudes at the windings of the transf... Continue Reading
Characterization and flotation studies were carried out on the Nasarawa-Eggon lead zinc ore sample through Chemical analysis, Mineralogical analysis, Petrological analysis, Work Index evaluation, Particle size/mineral assay analysis, Liberation studies Bulk Froth Flotation and development of a flow sheet. The chemical analysis was carried out using... Continue Reading
This project produced and evaluated a Self-propelled boom sprayer for small and medium scale herbicide application; with reduced drudgery and better effective herbicide application than the commonly used application machine in Nigeria, the knapsack sprayer. The knapsack sprayer was developed for spot spraying and its small coverage limits it to eff... Continue Reading
Modernization of our surrounding has resulted to widespread pollutants being disposed amidst which are heavy metals into the surroundings. Heavy metals are toxic to both human health and the environment even at low concentrations. Biosorption studies is considered as a method for the removal of heavy metals from dye wastewater due to its simple des... Continue Reading
The effect of thermal pre-treatments on the beneficiation of Ndit Ilmenite resource has been investigated in this work. The Ilmenite resource is located at Ndit village, in Bogoro Local Government Area, Bauchi State, Nigeria. The sample was sourced from four different points at 50m interval apart. The samples were homogenized then pulverized, sieve... Continue Reading
Reliability of power equipment in Ajaokuta Steel Company Limited (ASCL), Ajaokuta, Kogi State is as important as the company as a whole. The study presents the reliability analysis of critical Power Equipment in Ajaokuta Steel Company Limited (ASCL), using one of the distribution substation, 7DS (Engineering Shops & Auxiliaries including Housing Es...

A study was conducted in the laboratory on a crude oil contaminated soil treated with Bacillus licheniformis to investigate the suitability of the material for use as a liner material in waste containment applications. An indigenous hydrocarbon utilizing bacteria (HUB) was identified as Bacillus licheniformis and isolated from crude oil contaminate... Continue Reading
Black cotton soil (BCS) obtained from Baure; Yamaltu Deba Local Government Area was treated with up to 12 % palm kernel shell ash (PKSA) by weight of dry soil to determine the suitability of the treated soil for use in road construction. Index tests were carried out to classify the natural soil, while the moisture-density relationships were determi... Continue Reading
Pitchers, in their simplest form, consist of unglazed baked earthen pots, which are buried to their neck in the soil and filled with water, directly feeding the roots of the plants with a steady supply of moisture. Pitcher irrigation system is one of the most efficient traditional irrigation systems. Water seeps out of a buried pitcher due to the p... Continue Reading
Environmental noise pollution is an indicator of environmental degradation and its impacts in the sub-urban areas on the sustainability of life is an emerging concern. This has spurred this study on investigation of environmental noise pollution in 54 purposeful selected study points in Sabon Gari Local Government Area of Kaduna state. The noise me...
