This study has evaluated the effectiveness of metallic materials as chill in sand casting of aluminium alloy. Four plates of dimension 165mm x 80mm x10mm were cast using sand mould. Steel, copper and brass chills in form of cylindrical bar of geometry 7mm in diameter and 50mm long were inserted, side by side at regular intervals of 30mm in each sand mould and the last sample was left unchilled. Experimentation involved testing of mechanical...

87 Student Researchers

BACKGROUND TO THE STUDY

The increasing demand for education in Nigeria especially tertiary education has been an issue in recent times. Government–owned tertiary institutions as well as those privately owned do not possess the capacity and manpower needed to accommodate the growing number of young school leavers hoping to secure admission into any of these tertiary institutions.

Huang (2013) posits that predicting and evaluating the academic performa...

56. FORMULATION AND PRODUCTION OF ALCOHOL FROM PALM WINE.

87 Student Researchers

ABSTRACT

This research work was arrived as the formulation and production of ethanol (ethyl alcohol) from the fermentation of palm wine. A fresh palm wine was ated which was obtained  from Emene in Enugu State.  The characteristics that was tested before and after fermentation were; specific gravity, refractive index and PH value of the fermentated palm wine was first determined, after which samples were formulated for fermentation.  ...

57. EFFECT OF SPENT OIL (ENGINE OIL) ON THE PHYSIOCHEMICAL PROPERTIES OF SOIL

87 Student Researchers

    1. STATEMENT OF THE PROBLEM

Spent oil sometimes referred to as waste engine oil is produced from automobile mechanic shops and mechanical or electrical engine repairers’ shops (Anoliefo and Vwioko, 2001) after servicing the vehicles engines, generating set and other types of engines. It has dark brown to black colour and it is harmful to the soil environment (Adedokun and Ataga, 2007). This is because it contains a m...

58. OPTIMIZATION OF BIODIESEL PRODUCTION FROM YELLOW OLEANDER AND CASTOR OILS AND STUDIES OF THEIR FUEL PROPERTIES

87 Student Researchers

Abstract

 

The optimization of biodiesel production from two non-edible oils and studies of their fuel and biodegradability properties was carried out. The two oil feedstocks (Yellow oleander and Castor oils) were extracted from their seeds using an oil expeller and their physicochemical properties such as iodine value, moisture content, saponification value, acid value, viscosity, specific gravity and refractive index were determined. Most of these p...

61. CHANGE IN POLITICAL ADMINISTRATION AND ITS IMPACT ON THE ECONOMY: AN APPRAISAL OF THE MUHAMMADU BUHARI’S ADMINISTRATION

87 Student Researchers

Abstract

Change is a major part of our lives, whether it is change in industries, technologies or various sectors such as transportation, education, health care or social policies. But we still know little about when and how change occurs. On 29 May 2015, General Muhammadu Buhari was sworn in as the President of Nigeria. The Buhari-led administration is expected to urgently tackle several challenges that have hindered economic prosperity, sustainable security and o...

62. PRODUCTION OF ETHANOL THROUGH THE FERMENTATION OF REDUCING SUGARS RESULTING FROM THE HYDROLYSIS OF PRETREATED SAWDUST (HARDWOOD)

87 Student Researchers

ABSTRACT

The production of ethanol from food such as corn, cassava etc. is the most predominate way of producing ethanol. This has led to a shortage in food, inbalance in food chain, increased food price and indirect land use. This thesis thus explores using another feed for the production of ethanol- hence ethanol from cellulose. Sawdust was used to carry out the experiment from the production of ethanol and two methods were considered: SHF (Separate Hydrolysis and...

87 Student Researchers

ABSTRACT

The production of cassava flour by the method of traditional processing method (sun drying) and modern processing method (oven drying) was carried out using cassava sliced cubes or peeled cassava.

 

Indeed, the traditional Nigeria techniques of cassava flour production was studied with a view of achieving same product mechanically. Result of this studies show that the processing time can  be much reduce...
