Design and construction of 36W automatic solar street light using Solar panel, charge controller, led and with battery CHAPTER ONE INTRODUCTION 1.1Background Information Electricity is a general term comprising of a variety of phenomena resulting from the presence and flow of electric charge. These include many phenomena, such as lightning, static electricity, and the flow of electrical current in a cable. In addition, electricity comprises less familiar concepts such as the electromagnetic f...
This project covers the design and construction of a power generating windmill. The designs was carried out based on long-term available wind data of bida at 10m above the ground level. The average wind speed for Bida is 5.24m/s and rated turbine wind speed is 6.29m/s. The design of each components of the system were carefully constructed in a well equipped workshop within the school premises. Calculations were done manually for each components of the system and the results was match with the...

ABSTRACT Fiber optic communication systems have revolutionized the telecommunications industry, because it is used for faster transmitting of telephone signals, internet communication and cable television signal due to such lower attenuation and interference. The optical fibers are buried deep in the ground (1.2-1.5 meters) away from human activities. However, these fibers are been cut on frequently, the minute a fiber is cut, there is a halt in the smooth transition of signal. To prevent...
One of the widely debated topics in petroleum exploration in the management of its undesirable adverse effects on the environment. An accurate evaluation of the potential biophysical and socioeconomic impact will minimize the negative impacts of petroleum exploration and enhance the benefits thereof. Due to higher uncertainties associated with the potential presence of oil and gas in the Voltaian Basin, a 2-D seismic survey is carried out by Ghana National Petroleum Corporation (GNPC) to help...
Hydraulic fracturing plays a key role in the economic production of hydrocarbons from a reservoir by inducing permeable channels to improve the drainage area and to ease flow of oil and gas into the wellbore (Burton et al, 2002). A pressure transient test in Oredo O well, Oredo field located in Benin city, Nigeria, revealed a skin factor of +7.58 and flow efficiency of 0.53 (Kelechi et al, 2015). These are indications of a damaged well. PROSPER software (production system performance) has bee...
A model to predict the dry sliding wear behaviour of Aluminium-Jute bast ashparticulate composites produced by double stir-casting method was developed in termsof weight fraction of jute bast ash (JBA). Experiments were designed on the basis ofthe Design of Experiments (DOE) technique. A 2k factorial, where k is the number ofvariables, with central composite second-order rotatable design was used to improvethe reliability of results and to reduce the size of experimentation without loss ofacc...

Abstract In countries where industrialization is on the rise there is a corresponding increase in waste production resulting from industries which eventually upsetsthe environment and community for which they provide. While most of these waste generated are hazardous and should be managed, others could be put to appropriate use either directly or after been recycled. Most agro-waste can be recycled and be used asraw materialsfor manufacturing various products. This research is designed to inv...
ABSTRACT Soils containing large quantities of clay and silt are the most burdensome to the engineer. These soils exhibit marked changes in volume with changes in water content and consequently affect the function of any layer lain upon it due to its shrink and up heave behavior when used as a subgrade or a layer built of it. The test assesses the geotechnical characteristics of silty clay soil in order to increase the shear strength and decrease the compressibility of the soil, so that the b...
ABSTRACT This study comparatively analysed biogas production from three waste materials: Grass - Axonopus compressus, cow dung and pig waste slurry, with respect to the effects of carbon/nitrogen (C:N) ratio on biogas yield. A mixing ratio of 1:10 (one (1) part of substrate to ten (10) parts of water) was used. Nine 2L plastic digesters, were used for the study. Digestion was carried out in triplicates, 3 digesters for each substrate. The C:N ratios of the substrates were as follows: Axonop...
Creating a friendly workplace which is devoid of pollution is a top priority globally. This study assesses the impact of noise from a polythene nylon production and recycling factory. The HD600 Datalogging Sound Level Meter was used for the assessment of noise within the factory and at twenty-three sampling points outside the factory. A World Health Organization standard questionnaire was also administered to selected respondents within and outside the factory to obtain information on su...
The spread of pollutant in an area is partly a function of wood burning in local kitchens by the population of the area. This pollution generated through combustion of wood fuels presents difficult environmental challenges to societies as it could degrade the environment and affect human health and quality of life. Wood burning emissions are major contributors to air pollution in rural areas as they contain harmful gases. The level of carbon monoxide in the air in two location in oleh town ...
