ABSTRACT 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...

ABSTRACT 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
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
ABSTRACT 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
ABSTRACT In this work, we designed and constructed a digital counter circuit. The initial design criteria for the project were: to have a two digit output, to have the circuit count from 0-99, to include either a 555 timer or manual counter. Research was conducted into similar analogue electronic circuits and a suitable point of a digital die was... Continue Reading
ABSTRACT 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
ABSTRACT 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
ABSTRACT 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
ABSTRACT Automatic control systems penneate life in all advanced societies today. Such systems act as catalysts in promoting progress and development. 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...

ABSTRACT 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
ABSTRACT 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
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
Many physical processes are expensive or impracticable to observe directly, and certainly they can only be observed in operation under conditions that actually exist. Almost any industrial process, almost any natural biological, physical, or social environment, and almost any large computing system is quite complex. Such as, building a large... Continue Reading
ABSTRACT 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
ABSTRACT We re-examined the phenomenon of rotational instability in radio pulsars on decadal timescales using a sample of 315 radio pulsars whose spin-rates [rotation period (P) and spin-down rate ( P) ] have been measured on, at least two different epochs. The first stage of our analysis involves a direct comparison of the measured values of P... 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
ABSTRACT A drastic change in the perception of electric energy . But at the same time there is misreading of FREE ENERGY. Energy becomes free only at a point after which we don’t have to pay for power generation after hiring the unit. By using the magnetic force of magnets continuous motion (Energy) is made. This magnet also produces a... 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 The aim of this work is to examine the variations in meteorological parameters (Temperature, Atmospheric pressure, and Relative humidity)on the surface radio refractivity, N, in Lapai town, Niger state of Nigeria, with focus on the wet and dry seasons. Lapai town, being the study area, is located within latitude 9º 02ʺ N and longitude... Continue Reading
ABSTRACT 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
ABSTRACT 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
