ABSTRACT This study brought to the fore, a critical evaluation of the potentials of natural gas in the economic development of Nigeria. Natural gas option was considered the best alternative energy resource to other resources for optimizing income earning, indigent capacity building and the socio-economic development of an over populated Nigeria. Data and statistical reports from the various oil companies ere collaborated with the central bank economic report to determine the income generati...
ABSTRACT Automated Fish Feeder is a system, which focuses on aiding small scale fish farmers to feed their farms efficiently. By using Arduino and Internet of Things, this is made possible. This provides fish farmers with time and adequate information as the system is set to feed at several time intervals and send information through the internet should the feed container be low or empty . In addition, the system has so many potentials. The system can be embed into other systems such as a wa...
ABSTRACT Maintaining power system security of large power system is one of the challenging tasks to have secure operation point. The security assessment is an essential task as it gives the knowledge about the system state in the event of a contingency. Contingency analysis technique is being widely used to predict the effect of outages like buses, transmission lines, generators and inter-bus transformers, these may cause transmission line over loading and bus voltage limits violations. A...
ABSTRACT This world in which we are in is characterized by a multitude of natural phenomena. It is a world of change, of movement and energy; of storms, earthquakes, cosmic rays and solar flares. The range and complexity of these changes is so great, that it would seem the height of foolishness to attempt to find a common trend, or a theme that runs through them all. Never the less, men have come to the understanding of the factors involved. At the heart of such a science is the concept of en...
Abstract: Sequence stratigraphy model developed for the Ningning field is based on the interpretation carried out on the different wells that penetrated the various subsurface lithologies. Basically three depositional sequences were delineated from the five wells studied. The Vail model used made out a third and forth order stratigraphic surfaces that all fall within the central swamp depobelt of the Basin. The five wells used show the presentation of the interpretation and the models. All th...
ABSTRACT. Cost effective steel utilization as distinct from steel utilization is an engineering challenge of our time, especially in this austere period. Steel scrap recovery is defmitely one of the areas to be seriously looked into by Nigerian engineers. After estimating the recoverable steel scrap to the year 200AD, this paper aims at fmding an appropriate technology and size for steel scrap recovery bearing in mind the need for self reliance and the level of our technological advancement....

Abstract This Study Examined The Effects Of Effluent Discharges From Various Point-Loads On A Purposively Selected Receiving River, The Self-Recovery Ability Of The River And The Treatability Of Both The Discharges And The Receiving Stream In A Heavily Industrialized Community. The Work Involved Field Survey Of Industries Producing And Discharging Effluents In The Study Area (Ado Odo/ Otta Industrial Zone Of Ogun State, Nigeria); Determination Of The Effluents‘ Physico – Chemical, Biolog...
ABSTRACT This paper deals with the measurement of dielectric properties of some local cereals (com, beans, rice) in the audio frequency range (0.3- 20KHz) since dielectric properties of various agrofoods and biological materials are finding increasing applications, as fast and new technologies adapt/adopt these cereals for use in their respective industries and research laboratories. A Marconi instrument, 0.1% universal impedance bridge together with a specially designed and constructed coax...
ABSTRACT This work presents the first detailed, structural framework, characteristic and types of traps which are found in the South-Eastern part Rukwa basin, located in the Western Branch of the East African Rift System, South-Western Tanzania. The goal of this work is to examine the structural framework which control trapping characteristic of the Rukwa basin within the Karoo and Lower Lake Beds reservoir. 2D seismic datasets that were collected in 1983 by Amocco obtained from TPDC were an...
Abstract A novel study on biomass-air gasification using a horizontal entrained-flow gasifier has been conducted. The use of a horizontal entrained-flow gasifier reactor was employed to assess the effect of the gasifier reactor orientation on the gasification process. The gasification experiments were conducted at 800˚C and equivalence ratio of 0.23 while maintaining gas hourly space velocity (GHSV) of 8000 h−1 . Preparation and characterisation of wood powder were performed using classic...
ABSTRACT In Power line communication the information are sent via electrical power lines. The power lines are characterized by multipath fading and frequency selectivity due to impedance mismatch of the channel and impulsive noise. Therefore there should be a way to increase performance of the system. In this dissertation OFDM and MCSS modulation techniques were used to enhance PLC system performance. Bit Error Rate (BER) performance of OFDM and MCSS was analyzed and system efficiency was e...
ABSTRACT Modelling is a very important tool for understanding complex problems. A model plays a fundamental role in the analysis, design and development of complex systems, especially when physical testing and experimentation are not feasible - or not possible at all. Modelling technology holds tremendous promise for reducing costs, improving quality, and shortening the time-to-market for manufactured goods. Unfortunately, this technology still remains largely underutilized by industries toda...
Abstract A survey was conducted to assess the impact of water scarcity in Somntongo, in the lowveld region of Swaziland. The study adopted the use of questionnaire, interview schedules and focused group discussions. Information sought included sources of water, distances between water sources and places of residence, and the effect of water scarcity on the various aspects of human activities. The study revealed that only two rivers and five boreholes were the major sources of water while dist...
Abstract Effects of particle size, composite mix and cold water treatment on the compressive strength of Eremospatha macrocarpa–cement composite. Rattan–cement composites were manufactured using different particle sizes (0.60, 0.85 and 1.18 mm) of untreated Eremospatha macrocarpa cane and those treated in cold water using cement–sand ratio of 1:3 and 10% of rattan based on the cement mass. Specimens were tested for compressive strength after 28 days of curing. Increasing the particle si...
