Comparison Of Three Numerical Methods For Estimating Weibull Parameters Using Weibull Distribution Model In Nigeria
There is a crucial need in Nigeria to enhance the development of wind technology in order to boost our energy supply. Adequate knowledge about the wind speed distribution becomes very essential in the establishment of Wind Energy Conversion Systems (WECS). Weibull Probability Density Function (PDF) with two parameters is widely accepted and is commonly used for modelling, characterizing and predicting wind resource and wind power, as well as assessing optimum performance of WECS. Therefore, i...
AN INVESTIGATION INTO THE EFFECT OF FLOOD ON RADIOACTIVITY LEVEL OF WATER SEDIMENT IN MAKURDI RIVER BENUE STATE
In this work, the radiation monitor 4/4EC was used to measure radiations. The radiations in seven different locations were monitored and measured. The mean of all the readings were taken and subtracted from the background radiation and the radiological survey of the Makurdi River at seven different locations showed no gamma, beta and alpha measurements above typical background levels (5 to 25 at random intervals). The expected dose equivalence of the samples are within acceptable dose ...
OPTIMIZATION OF METHANE GAS BY ANAEROBIC DIGESTION
ABSTRACTThis 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 substances.Organic wastes, particularly plants wastes and animal dung constitute a nuisance to our environment and also a threat to public health, t...
THE DESIGN AND CONSTRUCTION OF AN ANTENNA BOOSTER (WI-FI ANTENNA BOOSTER)
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 to enable them have a seamless, uninterrupted and reliable communication. This project includes the steps for Biquad antenna constructi...
Design and Implementation of a Micro Controller Based Traffic Light System for Road Intersection Control
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, but the intelligence of this method was still limited to meet the deman...
Effect of some organic additives on compressive strength of clay bricks
ABSTRACTOrganic additives are agro-waste materials which when mixed with clay; improve its physical properties and its performance. These physical properties include compression strength, density, porosity etc. In addition to cost, challenges facing clay bricks are their reliability. The effect of some organic additives on compressive strength of clay bricks was investigated, were some possible organic additives, including Rice husk, Rice husk ash, Cow dung and Cow dung ash were considered. A...
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...
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...
