The physicochcmical characteristics of water in rivers of middle Galma basin were monitored at twelve stations during a period of two years. These stations were located at various points on river Shika, river Kubanni and river Galma. The parameters measured were pH, electrical conductivity, temperature, total dissolved solids, nitrates, phosphates,... Continue Reading
In this study, a simple four-mould hydraulic piston press biomass hollow briquette making machine, suitable for household and small-scale production of circular briquettes with a centre hole was developed. The briquetting machine was operated using a 4-tons hydraulic jack. Other members of the machine include: the mould, pistons, lower and upper co... Continue Reading
Dust carry non-spherical particles which in the absence of turbulence or shear wind and hydrodynamic forces, tend to orient their major axis in the vertical plane, thus resulting in particles anisotropy which may contribute to Cross Polarization Discrimination (XPD) degradation due to differential phase shift. This research presents an improved mod... Continue Reading
Optimal siting and sizing of Distribution Flexible AC Transmission Systems (D-FACTS) devices in power distribution networks maximizes loadability, compensates reactive power, minimizes power loss and enhances voltage profile. The search for optimal size and locations of these devices in radial distribution networks is challenging and requires robus... Continue Reading
This study had investigated the admixture properties of plantain peel ash through a series of laboratory experiments. This was targeted at obtaining an effective admixture while relieving the environment from the menace of environmental pollution arising from indiscriminate disposal of agricultural wastes. Plantain peel ash was blended with dry cem... Continue Reading
This research work presents the development of branch current based state estimation for Non-Technical Losses (NTLs) Detection and Localization. The use of weighted least square (WLS) state estimation for the evaluation of branch current of a network during theft is considered. In order to confirm the presence of theft in a network, current measure... Continue Reading
In the calibration of partial safety factor of steel reinforcement bars conducted in this study, necessary parameters (i.e. steel diameter, area, yield strength, ultimate strength, and elongation) needed for the calibration were obtained from the steel testing laboratory, Department of Civil Engineering, Ahmadu Bello University Zaria. The test resu... 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
One of the problems facing leather industries is to come up with an efficient way of reducing the organic pollutant loads of their wastewaters. This research dissertation was aimed at the preparation and application of ?-FeOOH and ?-FeOOH-SiO2-Al2O3 catalysts for tannery effluent treatment using Fenton oxidation process. Effluent at the point of di... Continue Reading
Queuing theory as a tool for optimising patients flow and resources utilisation in the female section of the OPD at Yusuf Dantsoho memorial hospital Kaduna, the study was conducted for a period of 5 days. Simple queuing theory calculations were done using the data collected in the evaluation of the performance characteristics of the system, i.e. th... Continue Reading
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
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
This research work presents the development of a Modified Link Budget for Low Earth Orbiting (LEO)-Based Land Mobile Satellite Communications System operating at Ku, K and Ka frequency bands by taking into cognizance the effect of additional loss due to Doppler frequency shift. Doppler frequency shift poses the problem of receiving higher or lower ... Continue Reading
This research was conducted to investigate the suitability of using a renewable, sustainable and environmentally friendly biodiesel as part or full substitute of the petroleum diesel. Biodiesel from Cotton, Jatropha and Neem seeds, were produced and their compositions were analysed using Gas Chromatography-Mass Spectroscopy. The biodiesels were the... Continue Reading
High-density polyethylene composites of date seed powder were prepared at filler loadings of 0 to 40wt%. The particle sizes of the date seed powder investigated were 72, 125, 150 and 180?m. Calcium carbonate was used as a reference filler. The high- density polyethylene composites were prepared in a two-roll mill machine and the resulting composite... Continue Reading
