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, but the… 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
The study investigated the spectral index of components of Compact Steep Spectrum sources (CSSs). The purpose of the study was to determine the symmetric nature of the CSSs. A sample of the CSS sources which is made up of 8 galaxies and 4 quasars was taken from the Extra Galactic Zoo for observation. These sources were observed at… Continue Reading

ABSTRACT The Geophysical Airborne gravity data of Abakaliki and Bansara area of Lower Benue Trough Nigeria was interpreted qualitative and quantitative in order to determine the sedimentary thickness/depth to basement and the possibility of hydrocarbons accumulation in the area and also to determine the density contrast 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
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 order… Continue Reading
Search for alternative materials required for shielding ionizing radiation has being on the increase for some period of time. Lead which is widely used is expensive, therefore researches has to be carried out on other materials. Clay has been suggested but it is not as effective as lead in shielding ionizing radiation. This work therefore… 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
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 super conductors… 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
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
There is a crucial need in the mainland regions of Nigeria to enhance the development of wind technology and engineering, which is essential for the designing of Wind Energy Conversion Systems (WECS). The Weibull Probability Density Function (PDF) with two parameters is widely accepted and commonly utilized for modelling, characterizing and… Continue Reading
This project is about the geophysical method with special emphasis on the use of resistivity method for groundwater exploration. the project was conducted at tarauni local government area of kano state. ABEM SAS 300C terramiter was used, electrodes, cables, reels of wire,and hammer are also used. the study area was generally underline by… 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
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
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
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

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
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
Thin films of Copper Nickel Selenide (CuNiSe) were synthesized on glass slides at room temperature using chemical bath deposition (CBD) method. The films were deposited from aqueous solution containing copper ion, nickel ion and potassium selenate (K 2 SeO 4 ) at varying molar concentration of nickel ion with constant time and pH of the… Continue Reading
