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 ...

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 ...

Renewable Energy in Nigeria: A Review

ABSTRACTOne of the most important resources of a nation is energy. The significance of energy definitely cannot be overemphasized as it is immensely utilized in our everyday activities as a very germane requirement for survival and robust lifestyle. The amount of energy availability and its usage in a country measures the level of industrialization. Several devices including machines, electronics, household electrical appliances and other domestic equipment and machines, industrial prod...

DESIGN AND CONSTRUCTION OF ELECTRICAL CODED DOOR LOCK SYSTEM

ABSTRACTWhenever we think of redefined security, we think of coded electrical door lock. It is a microcontroller based security door lock that can be used in homes, offices, laboratories, etc. for more reliable and high fidelity door control system, powered by electrons panel or electromechanical panels. Due to high rate of insecurity, especially intrusion into homes and offices, this project provides the users with an electronic keypad to enter the password required to get access into ...

DESIGN AND CONSTRUCTION OF A SOLAR POWERED MULTIPLE CELL PHONES CHARGING BOOTH

ABSTRACTCell phones need electric sources to charge their batteries in order to work, but there are people in developing and third world countries that find it hard to access electric sources.In an attempt to provide an alternative means of charging to those unfortunate areas in third world and developing countries, a solar powered cell phone charging booth is to be designed and constructed in this project.The goal of this project is to create a multiple output solar cell phone chargers...

CONSTRUCTION OF A 2.8KVA FUEL-LESS GENERATOR

Abstract In this work, a 2.8kva alternator was coupled to a 4 H.P dc motor acting as a prime mover to produce a fuel-less generator. The coupling was done using two crankshaft pulleys to match the speed of the alternator to that of the dc motor. Two 24v dc deep cycle batteries were also used as the exciter unit and a sustainable output voltage of 232V was achieved.   TABLE OF CONTENTSTitle PageDeclarationCertification. iiiDedication. ivAcknowledgement. vTable Of Contents. viLis...

Design and Implementation of Micro controller Based Smart Energy Meter Equipped with Prepaid Facilities

Today, humanity can be classified as living in a “machine society” where technological tools are predominantly at different levels interfacing in the day–to-day activity of man. These livelihood activities constitute and deliver economic, social and political benefits and potential risks to the survivability of nations –especially developing nations like ours.Energy meter has been classified as Electromechanical Energy Meters. It is regarded as the most traditional and widely used ene...

Analysis of Energy Auditing in Nigerian Power Systems

Abstract Energy  is  one  of  the  major  drivers  for  the  economic  development  of  any  country.  In  order  to  reduce  energy consumptions  for  sustainable  development, continuous  energy audit  of industrial  machines  become  necessary. Energy  audit  is  one  of  the  most  comprehensive  methods  in  achieving  energy  savings  in  industry  and  thus reducing  excessive  energy  consumption.  This  paper  analyzes  energy  audi...

Cuckoo Search Algorithm Optimization Approaches for Solving Economic Load Dispatch: A Review

ABSTRACT  Cuckoo  search  algorithm  (CSA)  is  an  effective  and  highly  reliable  swarm  intelligence  based optimization  approach.  It  is  a  technique  of  determining  the  most  efficient,  low  cost  and  reliable operation of a power system by dispatching the available electricity generation resources to supply the  load  on  the  system.  This  paper  presents  a  comprehensive  review  of  CSA  application  in Economic Load Dispatch (EL...

Stabilization Potential of Openly Burnt Coconut Waste AshesonA-7-5 Soi

Soil materials are a vital element in all civil engineering designs hence the first step in any geotechnical engineering project is to identify and describe the soil condition if not suitable, disposal or stabilization of the soil should be carried out . In lieu of these, this research was carried out to study the effects of coconut waste ash (CWA) derived from open uncontrolled burning on lime stabilized A-7-5 soil for road construction. Natural soil was collected from a borrow pit location ...
