ABSTRACT This research investigated the suitability of Mimosa pudica leaf (MPL) and Mimosa pudica stem (MPS) extracts as an inexpensive and nontoxic corrosion inhibitor for mild steel in acidic environment. The experiments carried out to investigate the corrosion inhibition of mild steel in 1.0 M HCl and 0.5 M H2SO4 by Mimosa pudica leaf and stem extract were weight loss and potentiodynamic polarization methods to determine the extract adsorption potential, kind of protection and its corrosio...
ABSTRACT Most often than not, project costs as estimated cannot realistically execute and deliver the project – an estimating inaccuracy called cost underestimation. Since cost estimates are the basis for decision making regarding project selection, underestimation lead to selection of project with significant cost risks. Researchers have so far failed to agree on the main cause of cost underestimation, therefore this research study is carried out to examine the problem of cost underestimat...
ABSTRACT The rate of maternal mortality in the recent time is so alarming due to weak health systems, poor doctor-patient relationship, and non-existence of e-health management system to efficiently maintain, handle the patient’s record and schedule appointments for pregnant women from the first to last trimester which will reduce unnecessary waiting line that causes stress to both the patient and doctors. This study aims at facilitating the maternal care delivery at Federal Medical Center,...
ABSTRACT Quality study of Otamiri River water around the vicinity of Umukoto Nekede Owerri where sand mining is carried out is discussed. The effects of these activities are explained by analyzing the positive and negative implications on the environment within the area. The socioeconomic ecology, vegetation, environmental hazards and physicochemical parameters of the water were examined by the method of laboratory sampling dredging technology, hydraulic procedures. The Numerical Quantitativ...
ABSTRACT The contamination of agricultural soil by quarrying activities has environmental and health implications especially the effect on bioaccumulation. Comparative study of contamination and distribution of heavy metals in three different quarry sites of Eziama in Umunnochi, Abia State, Nigeria was carried out in order to determine the concentration of heavy metals in quarry soil and their bioaccumulation in cassava tuber (Manihot esculentum). Soil samples were collected with aid of...
ABSTRACT This research work investigates Manpower Training and Development and Bank Performance in Nigeria (1996 – 2015). Manpower training and development is a critical activity that causes changes in an organization. It is an action that helps a firm to stay alive. However, many organizations ignore it. In spite of huge amount spent in teaching and developing the employees, so as to make them to be more productive, some organizations still perform poorly. This work aims at determining th...
ABSTRACT Conflicts are inevitable consequence of human interaction; and if not properly managed they can seriously hamper achievement of project objectives. This research study examines veritable strategies for managing conflicts in matrix organization structure of project management. The study was designed as a survey, and data was collected from 83 project participants using structured questionnaire. Relative Importance Index (RII) and Analysis of Variance (ANOVA) were employed as analyt...
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...
