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 of electric supply, fan, temperature sensor and...

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...

DISIGN AND CONSTRUCTION OF ALERT DETECTION SYSTEM

ABSTRACT In The development of ways to reduce malpractices in examination centers in all educational institutions is an important area of research. One of the major problems discovered aiding malpractices has been the creation of mobile phones, which however is a good communication device but needs to be curtailed during examinations. In order to have a 100% assurance that no student can cheat with his or her mobile phone a mobile detector system with a frequency jamming feature was develope...

The Geotechnical Properties of Soils along Appleton/Zoo Road

ABSTRACT This project was undertaken to determine the geotechnical properties of soils along Appleton/Zoo road. A total of nine (9) samples, both disturbed and undisturbed, were collected at chainages - 0+275, 0+325 and 0+525 respectively and each drilled to a depth of 1 m and at sampling depths of 0–0.3 m, 0.3–0.6 m and 0.6–1.0 m respectively. These samples were subjected to the following laboratory tests: Particle (grain) size analysis comprising determination of percentage ...

AbstractThe study examined the Knowledge and attitude of rural women towards agroforestry practices in Chikun Local Government Area ( LGA) of Kaduna State. The objectives of the study were to describe the socio-economic characteristics of rural women, describe the types of agroforestry practices, examine the sources of information on ageroforestry, find out the level of knowledge of rural women on agroforestry practices, ascertain the attitude of rural women toward agroforestry practic...

A COMPARATIVE ASSESSMENT ON THE EFFECT OF WATER INFLUX/PRODUCTION, FORMATION AND RESIDUAL FLUIDCOMPRESSIBILITY, AND GAS SORPTION ON THE VALUE OF ORIGINAL GAS IN PLACE USING THE MA

For  a  volumetric  gas  reservoir,  gas  expansion  (the  most  significant  source  of  energy)  dominates  depletion  behavior,  and  the  general gas  MBE  is  a  very  simple  yet  powerful  tool  for  interpretation.  However,  in  cases  where other  source  of  energy  are  significant  enough&nbsp...

Effect of seawater corrosion on medium Carbon steel 0.34%C and 0.36%C

This project covers a study of the effect of seawater corrosion on 0.34% and 0.36% carbon steel compositions.Two (2) specimens (steel rods) of length 150mm (each) for both steel compositions were obtained. Out of each was gotten four (4) specimens of 10mm length, 10mm diameter and two (2) specimens of 50mm length, 10mm diameter. This yielded a total of twelve (12) samples. For each steel composition, one (1) specimen of 10mm length and one (1) specimen of 50mm length ...
