Cassava (Manihot esculenta, Crantz) is an important perennial tropical crop for millions of people around the world particularly in Sub-Saharan Africa. It is preferred due to its agronomical attributes such as ability to grow in poor soils and drought resistance. Cassava storage roots are also a good source of starch. In addition, cassava… Continue Reading
The erratic pattern of rainfall over the years coupled with increasing population has left no option but to cultivate more farmlands through irrigation to meet food demand. Irrigated Agriculture as essential as it is if not done with care through good practices and use of quality water can lead to soil salinization and ecological… Continue Reading

They are integral components of any industrial society and are necessary for the production of standardized and quality goods. Suitable signal plans at each road intersections can be used to solve… Continue Reading
Turbulent flow is a type of fluid flow in which the fluid undergoes irregular fluctuations. The velocity of the fluid at a point is continuously undergoing changes in both magnitude and direction. Turbulent natural convection has been studied both numerically and theoretically. It plays an important role in the field of heat transfer and… Continue Reading
Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Drinking contaminated groundwater can have serious health effects. Diseases such as hepatitis and dysentery may be caused by contamination from septic tank… Continue Reading
This project work was carried out to access the level of electromagnetic radiation risk awareness from cell phones in selected audience of cell phone users using a Questionnaire. The reduction in the adverse effect of electromagnetic radiation from cell phones is theoretically explained in the research work. The Questionnaires were… Continue Reading
A Linear Variable Differential Transformer (LVDT) was constructed having a primary winding of 245 turns and two secondary windings of 100 turns each. The device was calibrated with a graduated cylindrical rod. The graduated rod when inserted between the hollow tube which has the windings gave output voltages of ±0.046V, ±0.51V,… Continue Reading
INTRODUCTION Physics as a science subject in school is different from other non-science subjects in school curriculum in the sense that its lessons take place in laboratories where both students and teachers carry out experiments and practical demonstration. This approach of learning and teaching of physics makes it a practical subject. Practical… Continue Reading
The concept of Superconductors in relation to energy gap was considered in this study. The occurrence of the Meissner effect indicates that superconductivity cannot be understood simply as the idealization of perfect conductivity in classical physics . The major aim of this project is to study the concept of energy gap in… Continue Reading
This research work is meant to determine the Earth’s stability from gravity anomalies and to provide diverse explanations for a wide range of physical observations and also highlight the factors affecting the stability of the Earth. Information from geodesy (shape of the Earth) and the gravitational field of the Earth studies have been fitted… Continue Reading
A derivation of equispaced-level conduction band Hamiltonians using the coordinate-transform based procedure is presented. The procedure start with the effective-mass schrodinger equation (Luttinger and Kohn, 1995), where the local conduction-band edge is interpreted as the potential experienced by and electron in a quantum well (QW). The… Continue Reading
Ionosphere is the region in the upper atmosphere where there are sufficient amount of electrons and ions to influence the propagation of radio wave. For radio wave propagation studies and application, a standard model (model based on data) such as IONEX map model was developed to study the ionospheric parameter i.e. the Total Electron… Continue Reading
Building materials are one of the potential sources of indoor radioactivity because of the naturally occuring radionuclides in them. Exposure to indoor ionizing radiation, like gamma radiation, results in critical health challenges. This work was designed to assess the indoor gamma dose rate level following the renovations of offices of lecturers… Continue Reading
ABSTRACT This project describes the design and construction of an automatic Battery charger. Automatic Battery chargers are not particularly cheap, but the protection they afford in protecting batteries against overcharging and possible battery damage is highly… Continue Reading
Using basic galvanic cell principles, the ability of tissues to generate electrical current through electrolysis was characterized. Studying Zn/Cu electrolysis in animal organs revealed a fundamental and measurable tissue-specific property – the galvanic apparent internal impedance (GAII), that is most likely related to the salt bridge… Continue Reading
ABSTRACT Nuclear Medicine is a medical specialty that allows modern diagnostics and treatments cancer using radio pharmaceuticals original radio-tracers (drugs linked to a radioactive isotope). Radio-pharmaceuticals are considered a special group of drugs and thus their preparation and use are regulated by a set of policies that… Continue Reading
Electrical resistivity method employing vertical electrical sounding was carried out in September, 2018 with aim to investigate favorable area for good groundwater potential. Four points were selected around the University clinic and female hostel for vertical electrical sounding (VES) using schlumberger configuration. Maximum current… Continue Reading
In this project (A Multi-Wavelength View of M17 Massive Star-Forming Region), efforts were made to determine the distributions of polycyclic aromatic hydrocarbons ( PAHs) within the M17 region. We find that PAHs are destroyed over a short distance or edge of the HII region. This PAH destruction edge can be located easily using Galactic… Continue Reading
The control of traffic at road junction, which was done purely by human effort, proves to be inefficient owing to the increasing rate of both motorists as well as the complexity of road networks. This inadequacy brought about the use of discrete solid-state electronics up to the usage of a computer controlled microprocessor,… Continue Reading
Wi-Fi signals are susceptible to signal loss as they travel hence Wi-Fi users are rarely completely satisfied with the signal strength offered by the off-the-shelf Wi-Fi cards, routers and access points. This project research intends to introduce a device which can provide Wi-Fi users with high signal strength and at a lower cost in… Continue Reading
This project work aimed at demonstrating the benefits of organic wastes in the production of Biogas using a bio-digester through the use of different substrates and methods in order to optimize the production of Methane Gas by anaerobic digestion. Five samples (substrates) were used in this research with their different seeding… Continue Reading
Viscosity is a property of a liquid and is defined as the resistance of a liquid toflow. This research is to determine the viscosities of motor oils (10w – 40w, 20w –50w), vegetable oil and honey using the fall sphere method. The viscosity of honeywith 4.44Ns/m2was found to be the highest and that of vegetable oil having a valueof… Continue Reading
