Investigation of Cement Mortar and Steel used in Reinforced Concrete in Nigeria
(2014-12-15)
The study explores the investigation of the chemical composition, microstructure and mechanical properties of steel and cement mortar used in reinforced concrete. The compositions and mechanical properties of the locally ...
Co2 Corrosion of the Welded Joint of an X65 Steel: Analysis of Surface Film Formed
(2014-12-12)
Carbon dioxide (CO2) corrosion, also known as sweet corrosion of steels has increased in recent years due to the injection of CO2 into oil wells in order to increase oil recovery and production. Despite the fact that carbon ...
The Impact of Low Density Polyethylene (water sachets) on the Mechanical Property of Cement Mortar
(2014-12-12)
Many building collapsed cases have been reported throughout the West African regions. It is recorded that during some of these subsidences, many lives are lost and the vast majority end up in hospitals and clinics with ...
Corrosion Behaviour of Low Carbon Steel used in Oil and Gas aboveground Storage Tanks
(2014-12-15)
The cost and losses associated with corrosion annually is approximately $ 276 billion or 3.1% of the GDP in the USA, 3 - 4% of GNP in Australia, Great Britain, Japan and other countries. The associated cost and losses ...
Induced Sickling of Erythrocytes Via Bending and the Effect of Mechanical Properties on Cell Pore Entry
(2014-12-15)
Patients living with sickle cell disease are perpetually plagued with painful crisis episodes, caused by vascular occlusion. Over time, this leads to oxygen deprivation and the eventual damage of starved tissues and organs. ...
Assessment of Iron Ore Mining Gangues in Itakpe for Secondary Recovery of other Metal Values
(2017-01-17)
Due to rapid industrialization, the demand for heavy metals is ever increasing, but the reserves of high-grade ores are diminishing. Therefore there is a need to explore alternative sources of heavy metals. Ore mine gangues ...
Adhesion and Optoelectronic Properties of Organic Light Emitting Devices (OLEDs) and Hybrid Organic-Inorganic Light Emitting Devices (HOILEDs) with Tio 2 Nano-Particles
(2010-12-17)
This study examines the basic operation of an Organic Light Emitting Device (OLED) and Hybrid Organic-Inorganic Light Emitting Devices (HOILED) by looking at the individual characteristics of the each layer which makes up ...
Effect of Annealing Temperature on the Formation of Methyl Ammonium Tin Tri-Iodide Perovskite Thin Film
(2016-07-12)
Organic-inorganic perovskite photovoltaics (PVs) have attracted a lot of attention as high- efficiency thin film PVs which are relatively cheap and easy to fabricate. Lead halide perovskites have shown a rapid rise in power ...
Design, Construction and Performance Evaluation of a Solar Drying System for Crops
(2017-03-22)
This research presents the design, construction, and analysis of the performance of a mixed-mode solar dryer for crops. A mixed-mode solar dryer utilizes direct solar radiation from the sun as well as input heat ducted ...
Phytoremediation of Crude Oil Contaminated Soil Using Cowpea and Indole-3-Acetic Acid as a Growth Hormone
(2017-03-22)
One of the unintended impacts of crude oil exploration is the pollution of agricultural land and aquatic resources when there is accidental oil spillage. The environmental effect of this has resulted in untold hardship to ...
