ABSTRACT In this study of the physics of stars and their astronomical identification, It is evident that stars undergo certain physical processes as they live through their life cycle. How gravity, magnetic field and nuclear fusion play a role in stellar evolution is explained extensively. This research describes the structure and evolution of... 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 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 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
ABSTRACT This work investigates the thermal properties of Polyvinyl Chloride (PVC), Plaster of Paris (POP), asbestos, and cardboard commonly used as ceiling materials. The steady state method for Lee’s disc apparatus was employed to determine these thermal properties which include, thermal conductivity, thermal resistivity, thermal diffusivity,... 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 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
ABSTRACT The Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) has updated the previous opinion on 'Possible effects of Electromagnetic Fields (EMF), Radio Frequency Fields (RF) and Microwave Radiation on human health' by the Scientific Committee on Toxicity, Ecotoxicity...

ABSTRACT The radiation dose received by the patient during the radiological examination is essential to prevent risks of exposure. The aim of this work is to study organ equivalent and effective dose s for common diagnostic radiographic examinations at General hospital... Continue Reading
ABSTRACT Thermal properties refer to characteristics of a material defining the substance and related to temperature dependent. The most important thing in building design is the protection of people who live and work within the environment. The research work identified some common roofing materials used for building design in Nigeria. . The... Continue Reading
ABSTRACT This study was undertaken to assay the elemental concentration in some Irish potatoes and soils from farmlands in an ex-mining area at Dahwol-vwana village, Jos-south L.G.A, Plateau state, Nigeria.... Continue Reading
ABSTRACT The radiation dose received by the patient during the radiological examination is essential to prevent risks of exposure. The aim of this work is to study organ equivalent and effective dose s for common diagnostic radiographic examinations at General hospital Dutsin-Ma local Government Area, Katsina State, Nigeria. We estimated the... Continue Reading
ABSTRACT Solar energy being transmitted from the sun through space to earth by electromagnetic radiation must be converted to heat before it can be used in a practical heating or cooling system. Solar energy collectors, the devices used to convert the suns radiation to heat, usually consist of a surface that efficiently absorbs radiation and... Continue Reading
ABSTRACT The phenomenology of jet in astrophysics was studied. Analytical methods were used to obtain an equation for describing jet motion. From the analysis, we understood that βT > 1, where βT is the apparent jet velocity along the observers line of sight. The observed motions of the components show curvatures and changes in velocity.... Continue Reading
CHAPTER ONE 1.0 INTRODUCTION During the last decade worldwide concern with global climate has highlighted the challenge faced by both industrialized and developing countries in maintaining a sustained process of development. Nigeria, like other developing countries, shares the need for fast economic growth given the current low standard of living... Continue Reading
ABSTRACT This research investigated the effect of magnetic field on the thermal conductivity of high temperature type II superconductors. The result suggested that the thermal conductivity of high temperature type II superconductor YBa2Cu3O7- decreases as the applied magnetic field increases at a given temperature. We also found out that the... Continue Reading
