ABSTRACT Biogas generation is accomplished by anaerobic digestion of biodegradable material in a biogas digester. Anaerobic digestion as a process requires dynamic model for predicting process performance. Mathematical model for biogas production from anaerobic digesters described in this study was used to predict biogas generation using experimental data. Multiple regression analysis was used in analyzing two sets of data, the first sets of data contains four different experimental results ...
ABSTRACT The broadcasting stations in Nigeria often encounter sudden failures, which results in loss of signal that causes the station to experience down-time. Causes of the failures could be traced to the issues that range from erratic power supply to degradation in the studio equipment. Each failure and its consequent down-time influences the reliability of the station. In our environment (Nigeria) reliability does not only depend on the established parameters, instead it includes paramete...
ABSTRACT The project is on the tDevelopment of Automobile Br&e Linings using materials and methods. Five dis= brake linings of the geometrical specification of Peugeot 504 series were produced using the available equipment at the Mechanical Engineering Department of the University of Nigeria, Nsuklira, The friction pads were made of varying proportions of palm kernel shell as the base friction material, rubber latex, rubber dust, sulphur, clay, brass chips and Epoxy Resins. Laboratory tests...
ABSTRACT The purpose of this work is to make a contribution to the “Abuja grand design” by proposing a strategy that would facilitate making Abuja feature as a “modern city”. This proposal is entitled “Policy and Regulatory Framework for Fiber Optic Backbone in Abuja”. The main import of the strategy is to network every home and business in Abuja with fiber optics. The city fiber network would serve as a broadband communication medium to provide essentially unlimited and open...
ABSTRACT One of the major problems encountered in rural and urban communities is that of traffic congestion and accidents at blind spots on the road. Several traffic control systems has been designed but in most cases it is targeted towards road intersections, T-junctions, and round-abouts, whereas, congestions and accidents on road blind spots is on the rise. This project, Intelligent Traffic Control System is aimed at controlling the traffic at such points. The system function is based on ...
ABSTRACT In the last decades, the power industry has had a gradual and steady change from the centralized bulk system (grid) where power is injected to the transmission network from generator to a more decentralized system where power is injected directly to a distribution network (embedded generation). Nigeria is not left out in this trend. In this assessment study, the Siemens’ PSS/E software is used to run the Newton-Raphson load flow program to see the effect of EG on loss reduction and...
ABSTRACT This research work reports the investigation carried out to determine the strength and microstructure of lateritic concrete containing palm kernel shell (PKS) as partial . replacement of coarse aggregates. The study employed different mix proportions, which resulted in casting and testing 148 cubes at 7, 14, 21, 28, 60, and 90-days of curing, to determine the best and economic proportion that will give compressive strength. The materials and methodology phase of this research evalua...
ABSTRACT Nigeria. a country in the tropics, is not free from tropical diseases. The commonest ones being malaria, typhoid and tuberculosis. Malaria alone results in over 300,000 deaths every year. Adding to this, there is a serious shortage of Doctors. A survey by the World Health Organization has shown that there is approximately I Doctor to about 2,660 Nigerians. Due to this. the Health sector is stressed beyond its carrying capacity and Doctors cannot perform at their best. Nigerians are ...
ABSTRACT The development of soil and rock properties for geotechnical design purposes begins with developing/defining the geologic strata present at the site in question. Therefore, the focus of geotechnical design property assessment and final selection shall be on the individual geologic strata identified at the project site. This research work was been carried out to determine the shear strength characteristics of soils in Ikole Campus of Federal University Oye Ekiti, Ekiti State. Classif...
ABSTRACT This research is focused at designing of water storage facilities of size 875,000 litres (750,000 litres for underground water storage, and 125,000 Litres for elevated steel tank) of treated wastewater and its transmission system for the storage and re-use of treated wastewater. The project is aimed to structurally design water storage facilities and its transmission system from the reservoir to the overhead tank for the re-use of treated wastewater in Covenant University. The...
ABSTRACT Yoruba is a dialect continuum of West Africa with over 50 million speakers. The indigenous is less spoken in our society because of the various trans-national structural revolutions going on in the world today in the name of globalization. Parents want their children to speak and learn English right from infancy and as a result, many aspects of the Yoruba language have been watered down. Many Yoruba words have virtually disappeared, and taken over by English loan words. Given to the...
ABSTRACT In this thesis, an embedded system which is closely monitored and controlled the climate parameters such as humidity, temperature, and light of a greenhouses based on wireless sensor network on a regular basis round the clock for cultivation of crops or specific plant species which could maximize their production was presented. The designed system comprises beside the sensors from microcontroller, monitor, wireless communication based on XBee and respondents such as fan, heater and ...
Abstract Castor oil is classified as semi-drying oil because it oxidizes on exposure to air, giving a gummy film, and can be highly sulphated to make it emulsible in water. In the raw condition it is seldom used in fatliquoring of leathers because crude oil does not emulsify with water and hence the failure of the fatliquor process. Castor seeds were collected, sundried, and crushed. Castor oil was leached in a soxhlet apparatus using hexane as a solvent. An oil content of 28.4%was obtained....
Abstract This research aims to program a data base of prominent and the most common diseases, which require supplementary oxygen care, by determining the specific range between the maximum and minimum dose, those can give a satisfied result. The minimum level will be given automatically, to increase the oxygen level and to determine the patient timing that will be subject to medical consultation and doctor's recommendations. The main objectives of this thesis are, over dose risk to be preven...
ABSTRACT The outgrowth and quick development in telecommunication technologies has open new opportunities for diagnosing of many diseases, which is life threatening, for patients who are in rural areas and district far away from city, and where there is no specialists. Not all of the diseases are to be diagnosed using telecommunication technologies. Critical and life threatening diseases, in which patient cannot wait until going to central hospital, or specialist, need to benefit from the ad...
