ABSTRACT The increasing rate of consumption of the common African catfish, Clarias gariepinus, a popular delicacy in Delta State, Nigeria has raised worries about the safety of health of consumers in the face of perceived increasing input of recalcitrant pollutants such as the heavy metals in the aquatic habitats of the organism. This research therefore investigated the bioaccumulation of some heavy metals (Pb, Cd, Cu, Zn, Co) in the muscle and brain tissues of the catfish, C. gariepinus sou...
Abstract Algae are large and diverse group of microorganisms that can carry out photosynthesis since they are able to capture energy from sun light. Algae may range in size from single cells as small as one micrometer to large seaweeds that grow to over 50 meters. Algae grow in the wide and are prompt to attack by predators and can easily be invaded which could result to competition that will eventually lead to low production of biomass which are important to organisms and the ecosystem. C...
ABSTRACT The purpose of this study is to understand the effects of power on the selection and implementation of enterprise systems (ES). Literature available on the enterprise systems research dealt more with ES implementation, critical success factors (CSF) for selection, implementation and post implementation management. Good number of studies also focused on ES selection. Very few studies combine selection and implementation in a single study. Though some IS researchers examine power and i...
ABSTACT This research assesses the challenges and prospects of maintenance in Onne ports operations. Data were obtained from eighty maintenance staff in Federal Ocean Terminal (FOT) and Federal Lighter Terminal (FLT) using questionnaire. Simple random sampling technique was used in selecting the sample used for this research. The Yaro Yamen formula was employed to determine the sample size. Data were converted from ordinal scale to interval scale and three hypotheses were tested with the a...
ABSTRACT The rapid advances in digital technologies have led to the rising need for the development of strategies to harness its potential, especially in the field of Information Systems. Despite this growing importance, there is still a fuzzy understanding of what constitutes a comprehensive Digital Business Strategy (DBS) which encompasses the dominant dimensions of strategic actions in the digital economy. It is worthwhile to note that the digital business strategy transcends one functiona...
ABSTRACT A detailed study has been carried out to determine the health risk associated with the level of trace metals and naturally occurring radioactive materials in the Birim River in East Akim Municipality of the Eastern Region of Ghana. The river runs through several communities in the municipality and serves as the main source of drinking water, irrigation and for domestic purposes. However, small-scale mining activities in the area are deteriorating the quality of the river water. Resul...
ABSTRACT This research focused on assessing the port performance: the queuing theory approach using Apapa port complex (APC) as the case study. The research was designed and carried out to answer among others the following questions: to assess the level of vessel turnaround time, traffic intensity, the waiting time of calling vessels at the port? Also, to determine the probability of vessel queuing on arrival at the port? To answer these questions only primary means of data collection were u...
ABSTRACT This study assessed the productivity and efficiency of airports in Nigeria employing the method of Data Envelopment Analysis (DEA).Two variants of DEA models were estimated and their outputs compared in order to enhance the robustness of the study. These models include the one based on Constant Returns to Scale (CRS) to characterise the input-output combinations and that based on Variable Returns to Scale (VRS). It is sometimes argued that DEA models generally tend to overestimate e...
ABSTRACT The unsanitary condition in which solid waste is temporarily dumped and disposed off has generated environmental concern through pollutions and health hazards. This calls for a need to map out suitable collection points and disposal point for effective and efficient management of solid waste to promote hygienic environment. This study is limited to the new Owerri inside Owerri municipal, Imo State. It focuses on site selection for solid waste collection having considered the existe...
ABSTRACT This project is carried out with the aim of x-raying the difficulties experienced by private developers in providing commercial housing for the people of Bayelsa State. The primary data for the study were captured through structured questionnaires. The data were analyzed using Pie chart distribution and analysis of variance statistical methods. The analyzed data were used to test the postulated hypothesis. The results showed that cost of site preparation and the terrain of the state...
ABSTRACT In this day and age the process of buying and selling of commodities are usually done not physically but virtually, with the current situation that the world is in at the moment the process of going to the market to buy groceries is a major risk to both the seller and the buyer.

ABSTRACT Housing has been described as an unstructured, complex, multi-dimensional phenomenon and its delivery as an important social policy issue. However, housing delivery in Nigeria is enmeshed in a myriad of perennial problems: huge housing deficits; acute shortages; overcrowding; high costs of building, renting and maintenance of houses. These are the outcomes of the extant policy driven persistently by the provisions approach frameworks that largely depend on implementation theory and ...
Abstract The study evaluated the effect of supply side factors on broadband penetration in Nigeria. The study analyzed the collective effect of supply side factors and the individual effect of supply side factors on broadband penetration in Nigeria. Two research questions were answered and two hypotheses tested. The population of the study consisted of 215experts from the major communication companies in the South East of Nigeria. The data used for this study were the socio-e...
ABSTRACT This study was to explore the effectiveness of the strategy adopted by the Government of Republic of Zambia to sustain rural water sources of boreholes fitted with hand pumps, using a case of Chongwe District. The Government of the Republic of Zambia adopted a strategy to reduce the rate of non-functional hand pumps for sustaining rural water supply under the National Rural Water Supply and Sanitation Programme (NRWSSP). Under the NRWSSP, the Sustainable Operation and Maintenance Pro...
ABSTRACT Online Role-Based Access Control (RBAC) is a flexible and policy-neutral access control technology that helps to reduce risk in management system. Role-based policies regulate the access to the information on the basis of the activities users perform in a system. The software was developed to reduce risk, conflict, fraud and stress that are daily occurrence in Tertiary Institutions. It motivates the subordinate to do better and perform well.
