ABSTRACT Generally, plastic is defined as long-chain organic material which can be formed into desired shape by the application of heat and pressure, also it extends to include so many organic metallic complexes and also certain long-chain inorganic material based principally on silicon, phosphorus, nitrogen, aluminum or boron or mixtures of these. It is still however true to say that the bulk of current commercial plastic are modified organic chemical, and that the inorganic polymers and th...
ABSTRACT In this research project, the various nail were subjected to six environments so as to check the effect of the environments on corrosion of the nails. Two sets of nails were used; normal nail and concrete nail. Six of each type while the other not coated. The research was carried out in the physical chemical laboratory of the institute of management and technology. The environments used are acidic solution, alkaline solution, salt solution, boiled water, air medium and lubricating...
ABSTRACT This report aimed at determining the presence and removal of mercaptan sulphur in kerosene using colour indicator method. It is known that impurities such as free sulphur, sulphur dioxide, marketers, finding materials etc. are found in petroleum products. Consequently, absorbents like molecular sieve, calcium oxide and even activated carbon could be used to trap these impurities, thereby making the product impurity free. The afficac of the absorption using calcium (Cao) �...
ABSTRACT This project was carried out to ascertain whether the local palm oil met the required standard. The analytical test carried out include the free fatty acid test the acid value, iodine value moisture, content, saponfication value, peroxide value, specific gravity, colour and viscosity. The specific gravity of the oil sample was determined by comparing its weight when filled with the sample and that of water, while its moisture content was analyzed by oven drying the sample for a pa...
ABSTRACT The design and construction of the House Bell with indicating light system was creative embarked on for the production of a better alarm signals. Meanwhile different measures and steps such as using electric bell, electric bulb, light emitting diode, 1 mm2 their cable, B Amps plug, lamp holder was used to achieve the objective. All the measures that were taken to ensure the functionality of this project were discussed in detail. Finally, conclusion and recommendation that will en...
ABSTRACT The very fundamental reasons behind this project assignment is to expose student to the very important aspect of private and independent research work not only theories but also subsequent translation of the theoretical research work into a particular function system. The project construction of automatic fence light controller has been done primarily as a photo type design it could be further modified suit the situation where it will be used e.g when used to activate an alarm the ...

ABSTRACT This is a technical project write-up design and construction were carried out by me with deep intensive and extensive research work. I all give credit to the authors of the textbooks whose I referred to in the cause of writing this project and its subsequent design and construction. In this project, I shed light on the basic principle of operation, the design and construction procedure. Critical analysis of all the functional parts of the transformer and rectifier connected to ...
ABSTRACT Engineering being the mother every technology cannot be neglected. Without practical application in the field of engineering. The student and their tutors are impotent. The lucrative nature of engineering depends on the technical know-how of the engineer. The purpose of practical project to students is to help them acquire practical knowledge in their choosing area of specification. It helps them to have a foretaste of the real world. This report is a comprehensive report on the pr...
ABSTRACT The uninterrupted power supply (UPS) is design to help in the offices, workshops and house hold appliances, due to the unstable power supply being supplied by (NEPA) presently known as Power Holding Company of Nigeria (PHCN) usually supply to us. With the help of the UPS we don't need to depend much on PHCN it is stress free because it don't need someone to change it over when light goes off, once there is any power failure it will automatically switched on and when power comes it w...
ABSTRACT This project the design an construction of fire alarm was carried out with deep intensive and extensive research work my aim and objective in the price of work is to produce a standard device or electronics that will inform the security about a fire outbreak in the company or house for a quick reaction/action. In this project I shade more light on the basic principles of operation the design and construction procedures the series of test conducted and so on to ensure that it work e...

Amplifiers, which are devices that increase the gain of an audio signal, dominate modern audio technologies. In this project, we designed and built an audio amplifier from scratch in order to demonstrate that such a key device can be constructed using basic electrical engineering principles.After performing major circuit calculations by hand, we modeled our circuit in PSpice, which is computer software that analyzes electrical circuits. In particular, we studied the variance that using budget...
ABSTRACT The project work is on the design and construction of automatic two lane traffic light control. This system is based on digital electronics. It employs an astable multivibrator which is the clock generator that sends the clock into a time sequencing generator using a decade counter with ten (10) decodes output that has it’s binary corded decimal (BCD) output into a diode or gate that sends logical data’s into a transistor switching circuit that switches the lamps that...
ABSTRACT This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to people. It is designed in such a way that it will take up 12v DC from battery and inverts it to an output of 220v, 50H2 AC. It makes no noise durin...
