ABSTRACT The city of Nairobi was initially engineered to keep stormwater out of sight and out of mind. Unfortunately, that approach has turned a potential resource into a waste product and created new environmental hazards. Once the rain falls onto the impervious surfaces of the streets, sidewalk, parking lots and rooftops, it picks up any and all pollutants that are in its path, gathering volume and speed into the storm drain where it is piped underground int...
ABSTRACT Polyethylene terephthalate (PET) bottles are plastic bottles derived from the raw material known as polyethylene terephthalate). The PET bottles are widely used for packaging carbonated drinks, beverages, food items, mineral water. Due to high consumption of PET bottles, trillions of PET bottles are disposed every year through, land filling, incineration, and ocean dumping; thus, creating nuisance and causing problem to the environment. This work aims to find an environmentally ...

ABSTRACT This project is titled the construction of a DC to AC inverter system. It is constructing to meet up with the power demand in the offices and in homes in the absence of power supply from the power holding company of Nigeria, PHCN. In order words the device / item serves as a substitute for PHCN which almost monopolises the power supply to people. It is constructing in such a way that it will take up 12v DC from battery and inverts it to an output of 230v, 50Hz AC. It makes no noise d...
Swine enterprise is one of the best options to choose when investing in livestock production, but has been suffering a big neglect due to lack of awareness and ignorance on the part of investors in most developing countries including Nigeria. Everything about swine enterprise depends on how they are managed as they do not demand much financially for their labour, feeding, housing and equipment selection and for other basic needs as compared to other livestock enterprise. Therefore, due to the...
Abstract: Wireless power transfer system charging multiple devices, through inductive coupling method which is classified under near field transfer region. In this project, we intend to achieve wireless power transfer charging multiple devices such as mobile phone, toothbrush and other low end power devices without the use of conventional copper wire or cable between the transmitter module and receiver module. In t...
ABSTRACT Phytochemicals are chemical compounds produced by plants, generally to help them thrive or thwart competitors, predators, or pathogens. These chemicals are produced by plants through primary or secondary metabolism (Breslin A,2017) . These work was done to determining the presence of phytochemicals such as Tannins, Saponin, Alkaloids, Anthraquinone, Phlobatannins, Flavonoids and Cardiac Glycosides (e.g Steroidal Ring or Terpenoids and cardenolide) from oil extracted from moringa...
Silicon dioxide , also known as silica (from the latin silex), is an oxide of silicon with the chemical formula SiO2, most commonly found in nature as quartz and invarious living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials existing as a compound of several minerals and as synthetic product.Notable examples include fused quart, fumed sili...

The project work assessed the volumetric shrinkage and hydraulic conductivity of lateritic soil-bamboo leaf ash admixture as liner materials for use in waste containment systems or structures such that the result shows effectiveness for use.
The development of a large scale multipurpose hot meal processing equipment was designed andsimulated for market oriented production as reported in this paper. This project involves thedesign, design layout and performance of the Hot Meal Processing Equipment. It has one compartment; the Agitator compartment. The Agitator has three curves like paddles arranged symmetrically and powered by an electric motor. The official...
Abstract. This research focuses on the design, fabrication and performance evaluation of a laboratory hot mounting press machine for metallography using locally sourced materials and indigenous technology. To achieve this research objective, working drawings were produced which were used to produce the parts of the machine. Mild steel plates were used for the housing and the movable platen while stainless steel and mild steel rods were used for the production of the mold and the stu...
Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals (additives) for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, removing contaminants from the engine, act as a cleaning agent, and act as an anti corrosion and cooling agent. Accordingly, this research effort focuses on comparative study of re-refined engine oils by acid treatment, acid/clay treatment, solven...
Abstract The 15th of October has been decreed a day to focus on germs specifically. It’s the germs on our hand that are in the firing line .The world health organization estimates that 3.5 million children die from diarrhea and lower respiratory tract infections each year. That’s why global hand washing day was decreed. Sanitation of hand has a great effect on the wellbeing of life in general. By maintaining ones sanitation different kind of diseases which are caused by contact can be pre...
Abstract Waste plastic disposal and excessive use of fossil fuels have caused environmentconcerns in the world. Both plastics and petroleum derived fuels are hydrocarbons thatcontain the elements of carbon and hydrogen. The difference between them is that plasticmolecules have longer carbon chains than those in LPG, petrol, and diesel fuels. Therefore, itis possible to convert waste plastic into fuels.The main objectives of this study were to understand and optimize the processes of plasticpy...
