THE EFFECT OF DENSITY VARIATION ON THE EARTH’S STABILITY OVER SOUTH-WESTERN NIGERIA

This research work is meant to determine the Earth’s stability from gravity anomalies and to provide diverse explanations for a wide range of physical observations and also highlight the factors affecting the stability of the Earth. Information from geodesy (shape of the Earth) and the gravitational field of the Earth studies have been fitted together to produce the complex factors affecting the stability of the Earth. This is obtained by developing a mathematical model of the geoid height ...

STATISTICAL ANALYSIS OF FACTORS AFFECTING STUDENTS’ ACADEMIC PERFORMANCE IN TERTIARY INSTITUTIONS

School, colleges and universities have no worth without student. Students are most essential asset for any educational institute. The social and economic development of the country is directly linked with student academic performance. The determinants of students' performance have been the subject of ongoing debate among educators, academics, and policy makers. There have been many studies that sought to examine this issue and the findings of these studies point out to hard work and disciplin...

The element present are Sodium (Na), Calcium (Ca), Magnesium (Mg), Zinc (Zn), Iron (Fe), Lead (Pb), Copper(Cu), Manganese (Mn), Potasium (K) and Phosphorus (P).it was observed that all elements...

Bio-guided Isolation, Purification and Chemical Characterization of Epigallocatechin; Epicatechin, Stigmasterol, Phytosterol

Spondias mombin (Linn.) is a widely cultivated edible plant used in folkloric medicine for the treatment of severe infection and health disorders. This research work was carried out to isolation, purification and chemical characterization the bioactive constituents of the ethyl acetate stem bark fraction of Spondias mombin (Linn.), a medicinally important plant of the Anacardiaceae family. This study revealed the presence of flavonoid and steroids, which have been found to be important hormon...

INDUSTRIAL GREYWATER RECYCLING AND REUSE: A SUSTAINABLE DEVELOPMENT FOR MILLIKEN & COMPANY, MIDDLETON

This report is a product of an extensive research project seeking to recycle laundry wash water for Milliken Industrials Limited, Middleton, U.K. Data gathered from meter readings in Milliken Industrial Ltd, Middleton, has constantly indicated the laundry aspect of their manufacturing process as by far, the process that consumes the largest volume of water, thereby resulting in high water utility bills. This singular process contributes significantly to the company‘s operating cost, since a...

DESIGN AND IMPLEMENTATION OF A CLOUD-BASED MOBILE LEARNING PLATFORM

ABSTRACT Mobile computing involves the use of portable handheld devices having network connections to access online resources especially via the internet. With mobile computing, people can collaborate from various distant location, they can be involved in conferences, online forums, symposiums, etc. One of such important services offered by mobile computing is Mobile learning. Mobile learning or M-learning has been realized as a convenient, efficient and effective way of learning. However, wi...

A COMPARATIVE STUDY OF THE ANTIBACTERIAL ACTIVITIES OF MEDICATED SOAPS ON SOME SELECTED BACTERIA FROM THE SKIN

Four medicated soaps (Ghana soap, Tetmosol, Beneks’, and Crusader) were investigated for their antibacterial activities against Staphylococcus aureus and Staphylococcus epidermis. A total number of thirty (30) students of Western Delta University, Oghara, Delta state, 15 males and 15 females were skin swabbed with sterile swab sticks. Identification of the bacterial species was by standard microbiological techniques. Crusader soap had the mean highest antibacterial activity (15.3 mm) agains...

IMPROVING NETWORK SECURITY USING ELLIPTIC CURVE CRYPTOSYSTEM

Securing a network wired or wireless for network administrator has been a big challenges for network administrators in the present day of Internet usage. This project presents ECDSA Cryptosystem as a solution to the problem been faced by network administrators and Engineers. The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analogue of the Digital Signature Algorithm (DSA) with the attractiveness that there is no sub exponential algorithm known to solve the elliptic...

Characterization and corrosion behavior of selected steels in 3.5M Sodium Chloride (NaCl) Solution

This research investigated the corrosion behaviour of selected steels (low carbon, medium carbon and high carbon steels) in 3.5 molar sodium chloride (NaCl) solution. The selected steels were cut into smaller sizes, after which they were heat treated and immersed in the corrosive media (3.5M NaCl solution) for corrosion test investigation. The immersion test was setup for 60 days for the comparative study of the behaviour of the selected steels in the corrosive media. Metallography of the ste...

SORBITOL NEGATIVE ESCHERICHIA COLIIN WATER LEAF (Talinum triangulare)

A total number of 60 samples of water leaf were collected from different areas in Enugu Metropolis, these samples were inoculated and examined to detect the presence of sorbitol negative Escherichia coli 0157:H7. About 35(17.5%) samples out of the 50 samples inoculated were found to be sorbitol negative E-coli. From the result E-coli 0157:H7 is the predominant serotype accounting for 90% of all VTEC isolates.

CORRELATION OF RADON IN PHYSICO CHEMICAL OF WATER (CASE STUDY: IBADAN, OYO STATE.)

ABSRACT Radon is a natural radioactive inert gas that is odorless, colorless and tasteless. It cannot be detected without special equipment and it occurs as a product of uranium decay. Radon is an unstable radionuclide that disintegrates through short lived decay products before eventually reaching the end product of stable lead. The short lived decay products of radon are responsible for most of the hazard by inhalation and ingestion. Radon and its decay products emit highly ionizing alpha-r...

CULTIVATION OF PLEUROTUS PULMONARIUS ON SAWDUST

ABSTRACT Pleurotus species are popularly known as oyster mushroom which are regarded as one of the edible mushroom of commercial important throughout the whole world. Utilization of this depends on the ability to secrete cellulolytic and hemilocellulolytic enzymes which can make use of wide spectrum of Agro industrial wastes for the growth and frutification. In this study potato dextrose agar was the only growth medium used to prepared the mycelia of P. pulmonarius. Then the culture was tran...
