Geoelectrical investigation of soils in Umudike area of Abia State was undertaken in order to determine the competence of the soils as foundation materials. A total of 18 Vertical Electrical Sounding (VES), using Schlumberger configuration was carried out. The results revealed three to six distinct geoelectric sequences with resistivities ranging from about 8 Ωm to about 38,000 Ωm and a variation in topsoil thicknesses with the l...

Abstract This study focused on the factors responsible for poor performance of senior secondary school students in mathematics in Onitsha Education Zone. The study was guided by four research questions. The study is a descriptive survey design. The targeted population consisted of senior secondary school students in Onitsha Education Zone. A total of 100 respondents were purposively selected by the researchers. The data were collected through the use of structured questionnaire after it was...
In Africa traditional studies have shown that herbal medicine proves to be one of the best forms of treatment mensure to preventing or managing a disease condition. Sida coryembosa is a plant gotten from the eastern part of Nigeria Nnewe north to be precise and certain claims and attributes has been said about the plant in wound healing and a possible treatment to peptic ulcer as a result of oxidative stress. The roots, stems and leaves were used for the research. 100grams of each was weighed...
ABSTRACT The main purpose of this project is to Analyze Road Traffic Accident (RTA) data in Nigeria, taking Anambra State as a Case of Study and to find out the major causes of such accident and suggest strategies for preventing or controlling them for the benefit of road users. An Analysis of Accident data recorded between the years 2004 – 2008 has yielded the following facts: over speeding and faulty tires are the causal factors of road accidents. These are but the majo...
ABSTRACT This article presents a framework for an information retrieval and indexing management system for a digital transcript system which will help overcome the undesirable problem associated with student’s grades, slow and strenuous accessibility of student report and records and poor information management within the school. The objective of this research is to propose and implement an algorithm that would optimize data and preserve them in an eco-friendly manner. A review was observed...
A comparative study was carried out for the determination of calcium and magnesium in milk and water melon (food sources of calcium and magnesium). Mixed standard solutions of calcium and magnesium (spike) were added to the samples before digesting with a mixture of concentrated nitric acid and concentrated hydrochloric acid (1:3). The calcium and magnesium content of the digest were determined using flame atomic absorption spectrophotometer (FAAS) and EDTA titration. The percentage recovery ...

In Financial Institutions such as banks and other firms, we face financial risk which emanates from different source. Credit Risk as one of the prominent risk, had been found to reduce the efficiency of banks and other financial firms, hence, the research to model the risk . In this project, several models used to evaluate credit risk, including their drawbacks, frame works and strengths are reviewed.
AIM OF STUDY The real value of Mobile learning lies not in accessing knowledge at any time, any placeand for anyone, but helping the right students to acquire the right skills and knowledge atthe right time in order to function as active and collaborative participants in theinformation based society. Thus, the aim of this project is to design a web-based learningsystem, which would provide the right students with�...
ABSTRACT In this paper we introduce, numerical study of some iterative methods for solving non linear equations. Many iterative methods for solving algebraic and transcendental equations are presented by the different formulae. Using bisection method, false position method, secant method and the Newton’s iterative method and their results are compared. The bisection, Regular Falsi, Newton-Raphson and secant method were applied to a single variable function over the interval [0,1]. Numerical...
ABSTRACT Hymenula cerealis, Neottiosporella radiata, Sphaerosporium lignatile, and Monilochaetes infuscans were isolated from soil of Botanical Garden, Obafemi Awolowo University, Ile-Ife. The soil sample was serially diluted and isolation was done using pour plate method. The organisms were then screened for cellulase production using carboxymethyl cellulase and Congo red. The screening result showed that Hymenula cerealis, Neottiosporella radiata, and Sphaerosporium lignatile are capable ...
Ionosphere is the region in the upper atmosphere where there are sufficient amount of electrons and ions to influence the propagation of radio wave. For radio wave propagation studies and application, a standard model (model based on data) such as IONEX map model was developed to study the ionospheric parameter i.e. the Total Electron Content. This parameter is used to quantify the level of ionization in the ionosphere. The performance of IONEX map model over Ilorin with station coordina...
ABSTRACTThe logs from three wells of Obama Field, offshore south-west of Niger Delta Basin were studied for the purpose of evaluating the petrophysical properties and interpreting the depositional environments. The analyses carried out involve delineation of lithologies, identification of reservoirs and fluid types, wells correlation and determination of petrophysical parameters of identified reservoirs and interpreting their environment of deposition. A suite of wire-line logs comprising gam...
Carbon black is a generic term for a particular form of elemental carbon manufactured by vapour- phase pyrolysis or partial combustion of hydrocarbons. It is the term for an important family of products that is used principally for the reinforcement of rubber, as a black pigment and because of its electrical, conductive properties It does not occur as a natural product (IARC, 2010) and it is one of the most stable compounds (Pilusa & Muzenda, 2013).
