ABSTRACT A common misconception about stainless steel is that it is not affected by corrosion. Although one of the main reasons why stainless steels are used is corrosion resistance, they do in fact suffer from certain types of corrosion in some environments and one of such types is crevice corrosion. Crevice corrosion is normally a consequence of a galvanic cell generated in specific areas with restricted flux. Crevice corrosion is a form of localized corrosion in which a metal in contact ...

ABSTRACT Blender is an electric machine for size reducing soft food or liquid mixture. Blender is some time called liquidizer consists of a glass jar or jug containing a steel blade assembly at the base driven by a small electric motor. Construction of blender was done based on the principle of size of reduction using electric motor as the major driver force. During the construction of blender, we adopted different stages which includes: The production of preliminary drawings with detail...

ABSTRACT This research is centered on the design and fabrication of copula furnace and atomizer for the production aluminium powder metal with the available material.0.4kg of refined coke was chosen as the basis for material and energy balance calculations and the design calculations performed from whose values are used to produce the design drawings.Mild steel was used for the internal linings of the furnace casing while other materials were selected based on functionality, durability, cost ...
ABSTRACT Waste and residuals are undeniably part of the human society. The accumulation of these materials and the “throw away” philosophy results in many environmental and health issues and safety hazard problems prevent sustainable development in terms of resource recovery and recycling of waste materials. The carbon sources in the waste can be converted to energy (electricity) using different technologies including collecting and converting current landfill gases, wet or dry anaerobic ...
ABSTRACTPackaging of food which is viable means of business opportunity has been exploited by individuals and corporate bodies for a very long time because the importance of packaging food products are very enormous ranging from protection of the product to preventing the food from spoiling. There is no way one can successfully go into business of chips production without exploiting a proper means of packaging the product. Over the years, different types of packaging machines have been deve...
ABSTRACTAn escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of usage are; shopping malls, airports, transit systems, convention centers, hotels, and public buil...
ABSTRACT Bioremediation is an important technology for the restoration of oil polluted environments by indigenous or selected microorganisms. In general, the rate of biodegradation depends on the number and types of micro-organism, the nature and chemical structure of pollutants to be degraded and the environmental conditions. In this study, the efficacy of the biodegradation potentials of foreign ( PETROX HC 500, PETROX HC 600, PETROX HC 100, PETROX HC 1150 AND PETROX HC 339 ) and local ma...
ABSTRACT: The interest in using Jatropha curcas L. (JCL) as a feedstock for the production of bio-diesel is rapidly growing. The properties of the crop and its oil have persuaded investors and policy makers to consider JCL as a substitute for fossil fuels to reduce greenhouse gas emissions. In this report, we gave an overview of the currently available information on the different process ste...
ABSTRACTBrazing alloys used for brazing the components of gas turbines and aerospace applications contain nickel as the base material. Nickel has highest affinity for oxygen. Incase if components are brazed using nickel as based filter material in air or atmosphere the braze joint will porous and braze strength is not achievable. To avoid the presence of oxygen while brazing, either inert gas furnace or vacuum furnace can be used. Vacuum furnace is superior to inert gas controlled by furnace ...
ABSTRACTThe designed Air Driven Engine is an economic friendly engine which operates with the aid of a compressed air. In principle, an Air Driven Engine uses the expansion of compressed air to drive the pistons of an engine. An Air Driven Engine is a pneumatic actuator that creates useful work by expanding compressed air. There is no mixing of fuel with air as there is no combustion.An Air Driven Engine makes use of Compressed Air Technology for its operation The Compressed Air Technology is...

Briquette is a block of compressed materials suitable for burning. Briquettes can be made from low cost materials such as old newspaper, any bio mass wastes and agricultural residues. They can be used as fuel instead of charcoal, firewood or mineral coal and costs less. Depending on which materials were used to make the briquettes, they may burn cleaner than charcoal. Finally, turning waste materials into a fuel source is attractive because it reduces waste as well as reducing the demand for ...
ABSTRACTVoting is a very important process in the Nigerian political system. It is one of the means and most effective method of ensuring a legitimate government through popular participation. To enthrone sound democracy and stability in the political system in Nigeria, a system of rig-free voting has to be put in place. Online voter registration systems supplement the traditional paper-based process, by which new voters fill out a paper form that is submitted to election officials, who c...
