ABSTRACT Body amour describes the object that is worn or carried to provide an individual protection against external energy. This research work was carried out to formulate powdered alumina for body amour application. Alumina powder (Al203), magnesium oxide (MgO), calcium oxide (CaO) and polyvinyl alcohol (PY A) were the materials used in the formulation procedure for the research work, the materials were mixed thoroughly to form six different formulation samples; binder and alumina po...
Abstract Covenant University aspires to be one of the ten leading university in the world by 2022. To achieve this noble goal, the university has set in motion various strategies, some of which are to improve the learning process of students, empowerment of faculty and staff in gaining skills in teaching methodologies and the use of e-learning/new technologies. The university has currently invested a lot of funds in the acquisition of relevant and contemporary e-learning technologies, such a...
ABSTRACT This project presents the design and construction of a microcontroller based Automatic Transfer Switch (ATS) for a single phase system. The ATS, which is based on a switch gear control system, gives a functional system that provides an automatic switching of power supply between a primary source (public utility) and a secondary power source (generator). The methods employed in designing the ATS involve the use of switching and power relays, Atmega8 microcontroller, diodes, resis...
ABSTRACT Not only do soils serves as underfoot" for roads, airfields. train tracks, and houses that sustain our complex society: Engineers, typically geotechnical engineers, classify soils recording to their engineering properties as they relate to its use as foundation support building material. The study of geotechnical characterization of soils in Ikole-Ekiti, Ekiti State was carried out to determine the index properties and strength properties of the soil. The laboratory test carried ...
ABSTRACT Domestic water supply is a daily necessity and key factor in human health and well-being. Without water, life cannot be sustained and lack of access to adequate water supplies leads to wide spread of diseases with children bearing the greatest health burden associated with poor water quality and sanitation. Drinking water is water that is of sufficiently high quality so that it can be consumed or used without risk of immediate or long term harm. Asin-Ekiti community is situated in I...
ABSTRACT Sand has traditionally been used as fine aggregate in structural concrete. It is usually imported from relatively distant places at high costs, and this increases the overall cost of making concrete and of providing housing in various Nigerian communities. This study investigates the performance of 409/o of laterite as fine aggregate in place of sand, and specifically seeks to determine whether lateritic concrete containing pies would satisfy the minimum compressive strength require...
ABSTRACT Auscultation is a technique, in which Physicians used the stethoscope to listen to patient’s heart sounds in order to make a diagnosis. However, the determination of heart conditions by heart auscultation is a difficult task and it requires special training of medical staff. On the other hand, in primary or home health care, when deciding who requires special care, auscultation plays a very important role; and for these situations, an ‘‘intelligent stethoscope’’ with decis...
ABSTRACT In an attempt to reduced non-renewable material usage, reduce green-house substances and at the same time be relevant to our environment, this research presents the progress of investigation going on to evaluate some properties of POEBA as partial replacement of cement in the production of structural concrete. This research work is carried out to determine the properties of Palm Oil Empty Bunch Ash (POEBA) when used as partial replacement for Ordinary Portland Cement (OPC) in concret...
ABSTRACT Rice Husk Ash (RHA) is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials. Grinded rice husk (GRH) and RHA is an agricultural waste product which is produced in large quantities globally every year. As the rice husk is piling up every day, there is a pressure on rice industries to find a solution for its disposal. Therefore as part ofa means to curbing this impending pollution problem. It is most essent...
ABSTRACT Agro-based and bio-wastcs generally referred to as solid wastes are good stabilization materials. Different solid wastes have been used by various researchers combining two or more at different times to treat soil and improve its engineering properties since the long term performance of any construction project depends on the soundness of the underlying soils. This paper has discussed the effect of the application of lime at varying percentages of 2%, 4%, 6% and 8%, oil palm frond a...

ABSTRACT The Reuse of waste glass in concrete production is among the attractive option of achieving waste reduction and preserving the natural resources from further depletion thereby protecting the environment and achieving sustainability. This present study examined the variation in the strength prope1ties of concrete using waste glass aggregate (WGA) as partial replacement for different coarse aggregates grading. 20mm and =(25mm coarse aggregates were partially replaced with WGA of respe...
A web-based information management system for national health insurance scheme(NHIS) will assist the body to have an online registration of people, health maintenance organizations (HMOs), accredited heath care providers, etc. Looking at the Nigerian population, access to health insurance is denied to a certain category of people as a result of not being a government worker or not privileged to be duly informed on the operation of the scheme and how to enroll Knowing that Health insurance is ...
ABSTRACT The condition and adequacy of the highway is often _judged by the smoothness or roughness of the pavement, deficient pavement conditions can result in increased user costs and travel delays, unnecessary braking and fuel consumption, vehicle repairs and probability of increased crashes. Pavement failure is usually a result of several factors which includes traffic impacts on the road, environmental factors, poor maintenance culture, geotechnical characteristics of the subgrade and ot...
