ABSTRACT This paper presents a mathematical model that could assist in measuring, monitoring and controlling temperature variation in cold and 'red-hot" metal working conditions or machining.
ABSTRACT A survey involving the use of questionnaires, personal communication, physical observation and photographic recording was undertaken in South western Nigeria comprising of Ekiti, Ogun, On do, Osun and Oyo states to identify the farm structures popularly used; materials used in their construction, their durability and maintenance culture adopted by the users. Farmhouses, cribs, barns, platforms, warehouses, silos, pens, yards and sheds, deep litter houses, palm fronds woven baskets, ...
ABSTRACT The motivation for the present study is derived from the fact that time management is an integral pan of good engineering practice.
ABSTRACT Contamination of oilfield cement slurries by drilling fluids is one of the causes of cement job failures and it results in expensive remedial actions. While the general adverse effects of Pseudo Oil Base Mud (POBM) contamination of cement slurries are known, little has been published on the actual effects of POBM on specific slurry properties. The effect of POBM on the filtration losses in oil well cement slurries was investigated. POBM contaminated slurries at varying contamination ...
ABSTRACT Irvingia gabonensis and Irvingia wombolu are species of bush mango commonly found in Africa whose kernel are processed into soup. Literature generally abounds on the nutritional composition of the fruits and kernel but there is dearth of information on the engineering properties which are very important in the design of processing equipment and machines. This study was designed to investigate the influence of moisture on some engineering properties of seeds and kernels of I. gabonen...
ABSTRACT Two of the largest manufacturing plants in Nigeria named plant A and plant B were studied and the data collected from the 10year period 1995-2005 from them enabled an analysis of their energy consumption, energy cost per tone, efficiency of energy use from exergy analysis and carbon dioxide emission rate
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. ...
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 ...
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...

The transient parameters have a significant impact on the magnitude of the fault currents generated within th...
ABSTRACT Most the domestic industries in Nigeria lag behind their foreign competitors when it comes to cost and quality.
ABSTRACT Road bumps play a crucial role in enforcing speed limits, thereby preventing over speeding of vehicle.
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.
ABSTRACT The dissolution response of y phase to thermal and mechanical effects in an inertia friction welded turbine disk nickel base super alloy RR1000 has been investigated.
ABSTRACT The study focuses on the influence of aluminium titanium boron (A5TB) master alloy on the fatigue behaviour of 6063al alloy.
