Causes of Roof Failure and Modelling of Pitched Roof Blow-Off in Southwestern Nigeria

ABSTRACT The increasing incidences of roof failures especially blow-off in recent times in Southwestern Nigeria has become worrisome in view of the damage done to adjacent structures and danger posed to building occupants and owners. There is the urgent need to devise methods to curtail failures and minimize the incidences of blow-off. This study was designed to investigate the causes and patterns of roof failures, recommend curtailment measures and develop a model to predict roof blow-off. ...

EFFECT OF INTERLEUKIN 4 AND RECEPTOR GENE POLYMORPHISMS IN RELATION TO OXIDATIVE STRESS DURING UNCOMPLICATED MALARIA INFECTION

ABSTRACT Parasitic infections such as malaria in host organisms often lead to oxidative stress condition resulting in the constant generation of free radicals and other reactive species in vivo that lead to extensive oxidative damage in bio-molecules such as DNA and proteins. Susceptibility of Plasmodium parasite to oxidative stress is a wellestablished feature and advantage has been taken of this property to design some prooxidant anti-malarial drugs. This study was carried out with the aim ...

Analysis of Ocean Renewable Energy (ORE) Research and Application in West African Region – A case study of Liberia

Abstract: The unbalance application of the hydropower and others renewable energy generation in west Africa, constant rise in the demand of energy, which leads to damping in the electricity supply and the importance of reducing greenhouse emissions, has brought the adoption of  clean renewable energy sources for generation of electrical power. One of these sources that have the potential to supply the world’s energy needs is the ocean (Home of waters). The current utilization of ocean area...

SHORT CIRCUIT MODELLING AND PARAMETER EXTRACTION OF A TURBO GENERATOR

Version:0.9 StartHTML:0000000105 EndHTML:0000007189 StartFragment:0000000141 EndFragment:0000007149 Short circuit modelling and parameter extraction of a synchronous generator entails development of a mathematical model of three phase short circuit of a turbo generator and the study of its characteristics or envelops at short circuit under constant speed and saturated conditions.. The transient parameters have a significant impact on the magnitude of the fault currents generated within th...

WHAT AND HOW ABOUT COMPETITIVE BENCHMARKING

ABSTRACT Most the domestic industries in Nigeria lag behind their foreign competitors when it comes to cost and quality.

VEHICLE SPEED CONTROL USING ROAD BUMPS

ABSTRACT Road bumps play a crucial role in enforcing speed limits, thereby preventing over speeding of vehicle.

TREATMENT EFFICIENCY AND ECONOMIC BENEFIT OF ZARTECH POULTRY SLAUGHTER HOUSE WASTE WATER TREATMENT PLANT, IBADAN,NIGERIA

ABSTRACT The efficiency of the poultry waste water treatment plant of Zartech Limited, Ibadan, Nigeria was assessed based on percentage reduction on the various water contaminants while the unit cost of treated water was compared with that supplied through tankers.
