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 limits ...

OPTIMIZATION OF METHANE GAS BY ANAEROBIC DIGESTION

ABSTRACT This 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, there is...

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 construction, ste...

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   demand   of   modern   age.   Thus,   the   needs  ...

Effect of some organic additives on compressive strength of clay bricks

ABSTRACT Organic 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 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 (EUV) and...

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

ABSTRACT Electrical 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 gro...

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 then dissi...

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 doses. So, in general, t...

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 Generator was mounted ins...

THE IMPORTANCE OF USING RADIOTRACER IN DIAGNOSING CANCER

 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 have been adopted by individual member of countries. The radio-pharmaceuticals used in diagnostic examinations are administered in very small doses. So...

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.

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

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 ...
