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...

CONSTRUCTION OF SOLAR CELL

Abstract: A solar cell or photovoltaic is a device  which directly converts photon or solar light or sunlight into electricity. Radiation (Light shining) on the solar cell produces both a current and a voltage which create  electric power in most solar panel. This process requires a Material Medium in which the absorption of photon raises an electron to a higher energy state, and the motion of this excited energy electron from the solar cell into an external circuit. The electron...

THE IMPORTANCE OF USING RADIOTRACER IN DIAGNOSING CANCER Review

 Abstract Nuclear Medicine is a medical specialty that allows modern diagnostics and treatments cancer using radiopharmaceuticals original radiotracers (drugs linked to a radioactive isotope).  Radiopharmaceuticals 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 radiopharmaceuticals used in diagnostic examinations are administered in very small do...

DESIGN AND CONSTRUCTION OF PERMENEMT MAGNET FREE ENERGY GENERATOR RESEARCH PAPER

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 magnetic field, so both the magnetic fields repel each other (like poles repel), which reasons the fins to move. The free Energy Generato...

Estimation of Naturl Radioactivity Levels in Some Food Spices Commonly Used in Nigeria and Its Radiological Risks

A spice is a vegetable substance of indigenous or exotic origin, which has a hot pigment taste that could be used to enhance taste of food or add to food some necessary stimulant ingredients. Knowledge of radioactivity levels in human diet is of particular concern for the estimation of possible radiological hazards to human health. In this study, the radioactivity concentrations of 40K, 238U and 232Th in some selected natural food spices commonly used in Nigeria were determined using gamma sp...

Baseline Studies of Terrestrial Outdoor Gamma Dose Rates of Ten Selected Markets in Port Harcourt Metropolis

In-situ measurement of background ionizing radiation of 10 markets in Port Harcourt metropolis of Rivers State, Nigeria was done using radiation meters and global positioning system. Two portable handheld nuclear radiation monitors (radalert100 and digilert200) to measure exposure dose rate at the various points and a GPS (Germin GPS map 76S for exact positions. The average exposurerates ranged from 0.011 mRh-1 (Mile 1 market) to 0.017 mRh-1 (Rukpokwu international market).The exposure dose r...

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...

Projecting changes of maize yield based on regional weather parameters using Artificial Neural Network

Maize is one of the largest food crop cultivated in Mubi region. It is produced annually and serves as the source of food and revenue. This work developed, an artificial neural network (ANN) model based on the data collected to forecast Maize yield in terms of weather parameters (Temperature and Rainfall). Predicted yield increased by 0.37 tons, 0.67 tons, 289.48tons and 0.17 tons in 2006, 2011, 2014 and 2015 and reduced by 0.52 tons, 0.32 tons, 5.53 tons, 15.44 tons, 0.45 tons and 0.25 tons ...

Assessing the influence of weather parameters

Rain serves as one of the key components in water cycle and it comes in the form of water droplets that are condensed from atmosphere and then fall on earth surface as rainfall. It has much importance. However, excessive rainfall can cause environmental hazards. This work developed an adaptive neuro – fuzzy inference system (ANFIS) to relate certain weather parameters (temperature and relative humidity) with rainfall in order to forecast the amount of rainfall capable of causing River Yazar...

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...

Quantum Gravity in a Nutshell 1

This math-free book is a good introduction to quantum gravity and has a lot of interesting history about the development of the theory since 1899. It's an informal introduction to a very difficult and doubtfully intelligible theory.- doubted even by its most ingenious contributors. The reader should expect that he/she will have to concentrate hard on what Balungi says but the rewards are significant. He is a talented physicist and a good writer. If you read it carefully and st...

Estimation of Global Solar Radiation Flux Over Ibadan

Renewable energy resources are those having a cycling time less than 100 years and are renewed by the nature and their supply exceeds the rate of consumption. Renewable energy systems use resources that are constantly replaced in nature and are usually less polluting. This project work estimates the solar radiation flux over Ibadan, a south-western city in Nigeria. The estimated models for the solar radiation over Ibadan are obtained for the period of ten years (1995 to 2004). The solar radia...

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...
