Statistical Analysis of Road Traffic Accidents

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...

Information Retrieval And Indexing Implementation For A Digital Academic Transcript System

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...

COMPARATIVE DETERMINATION OF CALCIUM AND MAGNESIUM IN FOOD SUBSTANCES USING EDTA-TITRIMETRY AND FLAME ATOMIC ABSORPTION SPECTROMETRY (FAAS)

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 ...

Comparative determination of Calcium and Magnesium in food substances using Atomic absorption spectrophotometry and EDTA Titrimetry

Credit Risk Models

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.

DESIGN OF A MOBILE LEARNING SYSTEM

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�...

APPLICATION OF NUMERICAL ANALYSIS TO ALGEBRAIC AND TRANSCENDENTAL EQUATIONS

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...

Identification and Characterization of Cellulase Producing Fungi.

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 ...

Performance of Ionex Map at Ilorin

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...

PETROPHYSICAL EVALUATION AND DETERMINING THE DEPOSITIONAL ENVIRONMENT OF OBAMA FIELD SOUTH-WEST NIGER DELTA

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...

THE CHEMISTRY OF CARBON BLACK

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).

Preliminary Investigation of the Possible Pathogenic Bacterial Contents of Some Local Non-Alcoholic Drinks

The aim of this study was to determine the safety profiles of some local non-alcoholic drinks sold within Zaria locality by isolating and characterizing the possible pathogenic bacteria found in them. For this aim, 17 samples of Zobo drink, 19 samples of Kunu zaki drink, and 15 samples of Ginger drink were analysed. Among the 51 total samples, Klebsiella pneumoniae was isolated from one Ginger drink sample; Serratia marcescens was  isolated from two Zobo drink samples and two Ginger drink s...

LEACHATE COMPOSITION OF ISALE-IJAGBA AND OKE –DIYA DUMPSITES IN SAGAMU AND THE POSSIBLE ENVIRONMENTAL IMPACT ON SURFACE AND GROUNDWATER QUALITY.

ABSTRACT When solid waste is disposed of at landfills, it undergoes a combination of physical, chemical and microbial processes. These processes help to transform the waste into various water-soluble compounds termed (leachate) and transfer the pollutants from the refuse to the percolating water, leading to contamination of surrounding groundwater and surface water. Characterisations of the leachate originating from the Isale-Ijagba and Oke-Diya dumpsites (situated in Sagamu, Ogun State, Nig...

Physico-chemical Properties of Cocoyam Flour

 ABSTRACT This work examined the physicochemical properties of cocoyam flour. Cocoyam corms were cleaned, peeled, diced, blanched, sundried, milled and sieved to obtain flour of fine particle sizes. Physical properties and chemical composition of the flour were determined in accordance with standard methods. The results of the physical properties ranged from oil absorption capacity 2.96 g/ml, water absorption capacity 3 g/ml, gelatinization temperature 68oC, least gelation capacity 0.4 g/ml,...
