Domestic water treatment using moringa oleifera seed powder

ABSTRACTMost people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these sources are turbid. Although, some inhabitants use alum to treat the water so as to make the water clear. But excessive usa...

DESIGN OF SIX-STROKE INTERNAL COMBUSTION SPARK IGNITION ENGINE

ABSTRACTThe rate at which energy is lost by human activities is enormous. There is need to work on how to generate more energy and minimize the usage of the generated energy. In an internal combustion engine, there is need to focus on gaining energy usage by using generated heat during combustion process. To reduce the energy usage, emission rate and improve the efficiency of four-stroke internal combustion spark ignition engine, the four-stroke internal combustion spark ignition engine is mo...

Construction of a DIGITAL AC VOLTMETER

This project- construction of a digital voltmeter seeks to utilize the microcontroller to build a digital voltmeter having better accuracy by utilizing a successive approximation analogue to digital converter ADC to measure the voltage (0 – 250V). Here, the working principal and components of this device are extensively explained. This Digital voltmeters (DVM) display the measured voltage using LCDs (Liquid Crystal Display) to display the result in a floating point format.

ADVANCED VEHICLE SIMULATOR (ADVISOR) PERFORMANCE CHARACTERIZATION OF A SERIES HYBRID ELECTRIC VEHICLE

Abstract: Series hybrid electric vehicle (HEV) formed by a combination of internal combustion engine and batteries/ultra capacitors in the appropriate ways, provides high-performance and high efficiency power systems for HEV applications. This paper discusses the performance characteristics of series HEV using advanced vehicle simulator. Different sizes of motor and engine were utilized with various battery capacities to explore the optimal component combinations. A comparative simulati...

DESIGN AND CONSTRUCTION OF A FAN SPEED CONTROL SYSTEM

                       AbstractThis temperature control fan can be controlled using a microcontroller when it detects acertain temperature that has been set. The purpose of this project is to prevent the waste ofvoltage usage when it is not hot enough for fan to be needed. The temperature control fanhas three different speeds. Each speed will change according to a certain level of temperaturethat is set. This project is a combination...

Use of an exergetic approach to analyze the performance of a vapor compression refrigeration system using a refrigerant solution of a nanoparticle (TiO2), mineral oil, and R410a (base refrige

ABSTRACTThis project illustrates the use of an exergetic approach to analyze the performance of a vapor compression refrigeration system using a refrigerant solution of a nanoparticle (TiO2), mineral oil, and R410a (base refrigerant). Exergy investigation is a thermodynamics strategy which allows for the assessment and improvement of a refrigeration system in terms of efficiency and performance with basis placed on the 2nd law of thermodynamics. The primary objectives of this project are to e...

Generation of electrical power through Gas turbine.

The major components of a gas turbine are compressor, combustors, turbine and generator. It operates by continuous drawing in fresh air into the compressor. The Air is then compressed to a high pressure in the compressor and discharge into the combustion. Here the air is missed with gas and burns continuous once ignited to increase its energy level at constant pressure. The high pressure and temperature combustion product enters an expansion turbine that converts the gas thermal energy into m...

DESIGN AND CONSTRUCTION OF PASSWORD HOME SECURITY SYSTEM

ABSTRACTThe necessity of a low cost electronic home security system designed in co-ordination with othersecurity measures is always there in our society to reduce the risk of home intrusion. Keepingthis problem in mind, we are working on a project on automatic password based door locksystem. We want to utilize the electronic technology to build an integrated and fully customizedhome security system at a reasonable cost. We hope this project will be useful in keeping thieves,dacoits and other ...

Heavy Metals Bioremediation Of Agricultural Soil Using Poultry Litter

The aim of this research is to determine the level of heavy metals contamination of agricultural soil and to reduce its concentration in the soil. Soil sampled at Inua Eyet Ikot, Mkpanak, Ibeno Local Government Area of Akwa Ibom State was analyzed to check for the initial heavy metal concentration of the soil. Poultry litter as a nutrient additive bearing microorganisms, bacteria and fungi was introduced to the soil to reduce the concentration of heavy metals. The sampled soil was mixed with ...

EVALUATION OF THE EFFECTIVENESS OF SOME AGRICULTURAL WASTE IN THE TREATMENT OF PRODUCED WATER

This study investigated the concentration of heavy metals in oil field produced waterfrom Niger Delta, before and after treatment with locally sourced agriculturalwastes. Two produced water samples were investigated for different metal ions suchas; Lead, Nickel, Cadmium, Copper, Iron, Magnesium, Chromium, Zinc,Manganese, Calcium, Arsenic, Boron, Tin and Barium. The produced water sampleswere treated with four different adsorbents which are; Orange peels, Banana peels,Palm Kernel Fiber and Luf...

STRENGTH ASSESSMENT OF NO-FINES CONCRETE PAVEMENT

ABSTRACTThe purpose of this project work is to assess the strength of No-fines concrete pavement. No-Fines concrete is use in low traffic volume, pathways, sidewalk and parking lots. No-fines concrete is produced by using ordinary Portland cement, coarse aggregates, and water. In this study, Two (2) batches of no-fines concrete each with two different water – cement ratio 0.36 and 0.45 and cement – coarse aggregate 1:4 and 1:6 were prepared to find the mix that generated high compressive ...

EFFECT OF FEEDING VARYING LEVELES OF COWPEA AND GROUNDNUT HAULMS ON GROWTH AND HEAMATOLOGICAL PARAMETERS OF RED SOKOTO GOATS

ABSTRACTThe study was conducted to determine the effect of inclusion level of cowpea haulms and groundnut haulms on the growth performance and haematological parameters of Red sokoto goats. Nine goats were allocated to three dietary treatments which were formulated to contain 40% cowpea haulms, 40% groundnut haulms and 20% cowpea ː 20% groundnut inclusion. In a Completely Randomised Design (CRD). Each animal was fed 2.5% of the body weight of the experimental diet for a period of 12 w...

Emerging Technologies: Ferroelectric RAM or FRAM

AbstractFerroelectric RAM or FRAM or FeRAM is one of a growing number of alternative non-volatile random-access memory technologies that offer the same functionality as flash memory. It combines the fast read and write access of dynamic RAM(DRAM) - the most common kind of personal computer memory - with the ability to retain data when power is turned off (as do other non-volatile memory devices such as ROM and flash memory). Because FRAM is not as dense (cannot store asmuch data in the same s...

Production of Bioethanol from Cassava Using a Hybrid of Saccharomyces Cerevisiae and Saccharomyces Paradoxus

ABSTRACT Cassava  is  considered  as  a  potential  source  for  the  commercial  production  of  bioethanol because of its availability and low market price. It can be used as a basic source to support large-scale biological  production of  bioethanol using  microbial amylases. With  the progression  and advancement in enzymology, starch liquefying and saccharifying enzymes are preferred for the convers...
