Some of the data used in this study have been published by Adewole and Healy (2013), among others. The authors especially acknowledge Professor David Macdonald for his invaluable contributions and co-supervising the research project. Our thanks are due to the Department of Petroleum Resources (DPR) and anonymous oil companies in Nigeria for giving permission to access some of the data for this study. E. O. A. also thanks Judith Christie, Clare Bond and other members of the Department of Geology and Petroleum Geology, University of Aberdeen, Aberdeen. We greatly appreciate the editor, and two anonymous reviewers for their critical assessments and vital comments, which tremendously improved the overall quality of the manuscript. Continuous supports on TrapTester software provided by Badleys, UK on the estimation of SI are much appreciated. The authors gratefully acknowledge the management of PCS Earth Techs Ltd.

A DESIGN OF AN OBJECT-ORIENTED DATABASE FOR EFFECTIVE DATA MINING

This paper focuses on the design of an object-oriented database (OODB), through incorporation of object-oriented programming (OOP) concepts into existing relational databases. The proposed approach makes use of the OOP concepts namely, inheritance, encapsulation and polymorphism to design an OODB and perform classification in it respectively. Usually, database is a collection of tables with common fields. In this study, those common fields are grouped together to form a single generalized table. The newly created table resembles the base class in the inheritance hierarchy. Polymorphism allows different classes to have methods of the same name and structure, performing different operations based on the calling object. The polymorphism is specifically employed to achieve classification in a simple and effective manner while Encapsulation ensures the hiding of the data and behavior of an object behind a limited and well-described interface. In Java terms, the limited and well-described interface is the set of public methods and attributes. The use of these object oriented concepts for the design of OODB ensures that even complex queries can be answered more efficiently. Particularly, data mining task and classification can be achieved in an effective manner.Â

Enhancing the Performance of Three White-rot Fungi in the Mycoremediation of Crude Oil Contaminated Soil

Contamination of soils by petroleum hydrocarbon is on the increase, particularly in the oil producing areas of Nigeria. White-rot fungi have enzymes which are capable of turning these organic compounds into harmless substances. This work investigated the performance of three white-rot fungi (Pleurotus tuber-regium, P. ostreatus and P. pulmonarius) for the remediation of different concentrations (0, 1, 2.5, 5, 10 and 20% w/v) of crude oil contaminated soils with sawdust and poultry manure as bedding materials. Ten grammes of each of the white-rot fungi were separately inoculated in each bottle containing exhaustively cropped topsoil (200 g), rice straw (40 g) and wheat bran (20 g). Each treatment was conducted in three replicates and arranged in a 3 x 6 x 3 complete randomised design. The bottles (54) were incubated for zero, one and three months in a dark room, exposed to light, watered daily thereafter for twelve days for fruiting bodies to spring out and harvested. P. ostreatus had best agronomic performance and P. tuber-regium removed hydrocarbons and heavy metals more than either P. ostreatus or P. pulmonarius under similar experimental conditions. The yield and mycoremedial performance of the three tested white-rot fungi demonstrated potentials for cleaning-up petroleum hydrocarbon contaminated soil, but their performance reduced from 5.0% (w/v) crude oil substrate contamination

1976 Universal Primary Education and Schooling Attainment in Nigeria

This study examines causal impact of 1976 Universal Primary Education (UPE) on individual schooling attainment in the Nigeria. This study exploits the quasi-natural experiment offered by the large-scale government investment in Universal Primary Education between 1976 and 1981 to confront the identification problems associated with this kind of study. Results from the Differences-in-Differences technique established that the UPE programme had positive and statistically significant impact on schooling attainment of beneficiaries. After controlling for all a large number of variables in the DID framework, exposure to UPE programme increases schooling attainment by 0.15 year. A formal test does not suggest that omitted variables might be influencing schooling outcomes

Nature of Arbitral Awards in Nigeria: an Overview

The need to explore other means of dispute resolution has resulted in the development of Alternative Dispute Resolution mechanisms, prominent among which is arbitration. Arbitration is the most regulated mechanism and is best suited for commercial relationships because, while it seeks to preserve existing relationships, it also ends in an award which is binding on the parties to the proceedings. The study examined the nature of arbitral awards through the lens of decided cases and the Arbitration and Conciliation Act, 2004. The study adopted the doctrinal method of research and relied on primary sources of information such as statutes, cases and conventions; as well as secondary sources of information such as books, journal articles and materials gotten from the internet, all subject to content analysis. The study found that the award, which is final and binding on the parties, has the same status as a judgment of the court in Nigeria when recognised and enforced, but may be set aside where any of the essential requirements are lacking. The study concluded by stating the need for everyone involved to take conscious steps from the beginning of the arbitration in order to end up with a valid and an enforceable award

Understanding Phishing and Phishing Techniques in Client-Side Web-Based Systems

As auspicious as the technology is, the bane of the internet has always been the constant threats of online identity theft and other forms of fraud prevalent on the information highway. Phishing is a form of internet fraud in which emails and websites that are purportedly from legitimate organisations and agencies are used to deceive users into disclosing personal or financial information. Despite the plethora of anti-spam filters that are readily available today, phishing emails are still able to bypass such measures and find their ways into users’ inboxes. This challenge at the client side of the web-based infrastructure is prevalent as clients are at varying levels of usage and knowledge of internet infrastructure. This paper takes a look at the phishing scenario by examining why it works. We provide extensive insights into extant literature in the subject domain as a basis for the development of tools to mitigate phishing and assisting users understand phishing attacks

Hypertensive heart disease in Africa

Hypertension has become an important public health problem in Africa. Currently an epidemiologic transition from infectious diseases is going on in the continent and the prevalence of chronic diseases like hypertension is increasing. The response of the heart to the stress/afterload imposed on the left ventricle by the progressively increasing arterial blood pressure is described as hypertensive heart disease. Hypertensive heart disease and failure are the commonest cardiovascular diseases of Africans. Since hypertension is a treatable cardiovascular risk factor, there is need to create more awareness about the disease and educate our patients concerning drug compliance. There is also a need for longitudinal multicentre study in Africa, in order to assess the severity and burden of the disease
