Four Junction Traffic Light

ABSTRACT  The control of traffic at road junction, which was done purely by human effort, proves to beinefficient owing to the increasing rate  of both  motorists as well as the  complexity  of  roadnetworks. This inadequacy brought about the use of discrete solid-state electronics up to theusage of a computer controlled microprocessor, but the intelligence of this method  was stilllimited   to   meet   the   demand&nb...

A MULTI-WAVELENGTH VIEW OF M17 MASSIVE STAR-FORMING REGION

ABSTRACT 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 Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) band-ratio images. We try to find out the relative roles of extreme ultraviolet...

A GEOELECTRIC SURVEY OF UNDERGROUNDWATER AT AL-QALAM UNIVERSITY KATSINA CLINIC USING VERTICAL ELECTRICAL SOUNDING

ABSTRACTElectrical 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 electrode separation of 160m to 200m was used. The investigation was carried out using Terrameter Allied Ohmega. The survey was able to investigate grou...

EFFECT OF MATHEMATICAL KNOWLEDGE IN TEACHING AND LEARNING PHYSICS

This research work is set to find out the effect of mathematical knowledge in teaching and learning of physics.  The research was carried out with the view of sourcing out explanations as to why there are problems in teaching methods that affect academic performance of students. Such problems include the inability of teachers to: 1.     Translating learning research into practice: The lack of time for reading research results and interpreting them among teachers...

THE IMPORTANCE OF USING RADIOTRACER IN DIAGNOSING CANCER

 ABSTRACTNuclear 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 have been adopted by individual member of countries. The radio-pharmaceuticals used in diagnostic&nbsp...

CORRELATIONS BETWEEN ELECTRICAL PERFORMANCES OF POTATO BATTERIES TREATED UNDER THREE DIFFERENT CONDITIONS.

ABSTRACTUsing 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 function of tissues delineated by electrodes.We now report on new fundamental studies on GAII in vegetative matter and on a simple way for significan...

Design and construction of an automatic Battery charger

                                                         ABSTRACTThis 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 desirable. However the work carried out through the construction and design of an inexpensive alternative to the commercially available fully Automati...

Indoor Gamma Dose Rate Exposure Levels in the Faculty of Science, University of Ibadan

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 in Faculty of Science, University of Ibadan using RDS-30 Survey meter. Measurements were made at 110 locations after renovations and in some selecte...

Performance of Ionex Map at Ilorin

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 Content. This parameter is used to quantify the level of ionization in the ionosphere. The performance of IONEX map model over Ilorin with station coordina...

DESIGNING AN EQUISPACED LEVEL QUANTUM WELL IN THE ULTRA TIN LAYER OF A SEMI CONDUCTOR ALLOY

ABSTRACTA 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 electron effective mass variation is proportional to the potential variation within the a QW, and the well has equispaced bound state.In sem...

THE EFFECT OF DENSITY VARIATION ON THE EARTH’S STABILITY OVER SOUTH-WESTERN NIGERIA

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 together to produce the complex factors affecting the stability of the Earth. This is obtained by developing a mathematical model of the ge...

CONCEPT OF ENERGY GAP IN SUPERCONDUCTORS

ABSTRACTThe 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 other objectives of this study are to appraise the rate of superconductivity for energy gaps and to appraise ...

Ground water detection using electrical Resistivity method at taraurni local government of Kano state

ABSTRACTThis 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 three (3) to four (4) geoelectrical/geological layer. the lateric soil has resistivity of 212 ohms-meter with thicness of 1.6 meter and depth of 1.6 ...

CONSTRUCTION AND CALIBRATION OF A LINEAR VARIABLE DIFFERENTIAL TRANSFORMER (LVDT)

ABSTRACTA Linear Variable Differential Transformer (LVDT) was constructed having a primarywinding of 245 turns and two secondary windings of 100 turns each. The devicewas calibrated with a graduated cylindrical rod. The graduated rod wheninserted between the hollow tube which has the windings gave output voltages of±0.046V, ±0.51V, ±0.088V, ±0.155V, ±0.271V and ±0.395V for displacements of±0.00cm, ±2.00cm, ±4.00cm, ±6.00cm, ±8.00cm and 10.00cm respectively. Thedevice when used...

ASSESSMENT OF SECONDARY SCHOOL STUDENTS’ ACQUISITION OF SCIENCE PROCESS SKILLS IN PHYSICS IN NSUKKA LOCAL GOVERNMENT AREA OF ENUGU STATE

INTRODUCTIONPhysics 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 work is encouraged in science subjects (physics inclusive) because it facilitates the learning and understanding of science concepts, and in developi...
