The physicochemical and bacteriological qualities of effluents from WUPA Sewage Treatment Plant, Abuja were determined within the duration of twelve weeks. Grab method of wastewater sampling was used while sampling for the analysis. The sampling and analysis were carried out between May and September, 2015. Samples were collected at the inlet to th...

One of the requirements for enabling two nodes to communicate through a network is the existence of a fully connected path between them. However, there are scenarios in wireless networks where this is not the case and yet nodes still need to communicate freely. Despite concerted efforts to resolve this problem of unconnected wireless nodes trying t... Continue Reading
Admission Control is a vital component for end-to-end Quality of Service (QoS) delivery in a packet flow network. It is more effective when implemented at the edge of the network. The edge of a mobile network is dominated withmultiplexer which either uses Synchronous Digital Hierarchy (SDH) or Wavelength Division Multiplexing (WDM) for transport. T... Continue Reading
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
Over the years, oil spillage has been precarious and most of the time unpredictable. It misbalances the ecosystem directly and indirectly on a rampage scheme, claiming thousands of marine lives; animals and plants and in some cases humans too. Whenever it occurs, the oil being less dense than water floats on it, which simply means that there is no ... Continue Reading
This research work utilized the silica obtained from locally sourced kaolin (from Kankara in Katsina State) to produce zeolite grade sodium silicate as a raw material for the preparation ofsilica sol for ZSM-5 synthesis. The work also involved development of sodium silicate pilot plant. Of the various dealumination routes considered, double dealumi... Continue Reading
Management Strategies for Gravity Sprinkle Irrigation Systems by Aliyu Abubakar Ramalan, Doctor of Philosophy Utah State University, 1988 Major Professor: Dr. Robert W. Hill Department: Agricultural and Irrigation Engineering The study reported herein examined various management strategies which can be implemented for equitable allocation of water ...

While mechanization is known to enhance production and reduce drudgery, powering agricultural machinery entails energy consumption withattendant financial and environmental costs. Financial costs in agricultural mechanization is exacerbated by the rising energy prices due to ongoing energy sector liberalization and this has negative impact on the p... Continue Reading
Rice husk, a potential source of activated carbon, is locally available in Nigeria but underutilized thereby constituting solid waste menace in the environment. Incidentally, large volume of wastewater containing high concentrations of toxic contaminants such as phenol and other contaminants are continuously being generated as a result of increased...

In this study, the effects of methanolic leave extracts of Combretum micrantum (CM), Combretum Glutinosum (CG), Ficus exasperate (FE) and Ficus platyphylla (FP) on the corrosion of A356.0 type Al-Si-Mg alloy in 3.5 % NaCl aqueous solution were determined. It evaluated the inhibition efficiency of each of the inhibitors and determined their mechanis... Continue Reading
This research is aimed at the development of a cultural-algorithm based artificial bee colony algorithm (CABCA) for improved Proportional Integral Derivative (PID) controller parameters tuning. The normative and situational knowledge inherent in cultural algorithm were utilized to guide the step size as well as the direction of evolution of Artific... Continue Reading
All nations of the world depend on fossil fuels for their energy needs. However the obligation to reduce Carbon dioxide and other gaseous emissions is the reason behind which countries turn to non-polluting renewable energy sources. Hot water heated by the sun is used in many ways, in residential settings to provide domestic hot water, also has ind... Continue Reading
Agricultural products upon harvesting have high moisture content which makes it unsafe for storage as the moisture in the crops attracts microorganisms which result in deterioration of the products. The major shortcoming of multiple trays drying is uneven drying of the products being dried on different trays.Solar dryers with and without thermal st... Continue Reading
There are several energy saving algorithms proposed to save energy in heterogeneous networks, but most of these algorithms achieved energy savings at the expense of service provisioning. Base stations significantly contribute to power consumption in cellular networks. This research work presented a Data Rate-Based Sleep Mode Algorithm for energy sa... Continue Reading
