ABSTRACT This research work deals on efficient contract management and its effect on project delivery. The need for the research arose due to rampant project delays and abandonment in the country and their adverse effect on the national economy. Both primary and secondary data sources were used to obtain the data for the research work. A structured questionnaire based on the 4-point lickert scale was used to collect data from the respondents. The results of the analyses indicate that there...
ABSTRACT Background: Tuberculosis (TB) remains a major threat to public health despite several efforts to curb the disease. Contributions made by TB control programs have been tremendous; however, the emergence of multi-drug resistant (MDR) tuberculosis is a big threat to the control efforts and calls for innovative measures to mitigate the effect. New TB control programs with a comprehensive approach to dealing with MDR-TB is needed globally. In particular, new nonsputum based diagnostic to...
ABSTRACT Application of IT in institutions of higher learning has become unavoidable and remains constantly increasing. Many institutions are investing heavily in IT in order to stay competitive. Studies have however shown that majority of these investments do no deliver value. The higher education sector is believed to be one of the sectors with high IT investment wastage. It is for this reason the concept of IT-Business alignment which involves finding harmony between IT, and business strat...
ABSTRACT This study shows the effect of changes in GDP, population, foreign trade and seaport access corridors of ECOWAS member countries, especially the littoral States, on the growth of freight volumes of their respective economies. The primary aim of the research is to develop a short sea shipping model for the ECOWAS sub-region, with the objective of reducing the cost per transported unit within the sub-region and predicting the growth of short sea shipping freight in ECOWAS economies. ...
ABSTRACT This study re-assesses the radiological hazards of Naturally Occurring Radioactive Materials (NORM) on workers and the general public due to continuous exploration and production of crude oil and waste generated from the Jubilee Oilfields of Ghana. The specific activities of 234U, 238U, 230Th, 232Th, 226Ra, 210Pb, 234Th, 228Ra, 224Ra and 40K in crude oil and NORM waste samples have been estimated using Sodium Iodide detector and alpha spectrometry after radiochemical separation. A t...
ABSTRACT Soils and cassava tubers in Okigwe auto-mechanic village of Imo state were investigated for presence of Polycyclic Aromatic Hydrocarbons (PAHs) and heavy metals. Six soil samples of 0 - 15 cm and 15 - 30 cm in depth were collected each, at 3 sites, in close proximity to selected automobile workshops. A distant location was used as the control site. Physicochemical properties of soils from this study area were investigated using standard methods, PAHs in the soil and cassava tubers ...
ABSTRACT This study is aimed to investigate and analyze the implementation of constructability in project delivery process in the Nigerian engineering / construction industry using Rivers state as case study area.Data was collected through questionnaire and interview approach. Analysis of data was carried out with the use of SPSS V16.Results of data analysis revealed that although a high percentage of the sampled population are familiar with the term “constructability”,nearly alldo not h...
CHAPTER ONE INTRODUCTION 1.0 Background Information The seaports are very important to the Nigerian trade as practically all imports and exports move through the ports. The importance of the seaports is attested to by the fact that approximately 99% by volume of Nigeria total imports and exports are seaborne; Nigeria ports control 60% of import into West and Central Africa. The ports have served as a major determinant of how economic activities are distributed. The volume of cargo-throu...
ABSTRACT As competitive strategies shift to the area of quality management, this research seeks to predict contributions of input variables to quality outcome. The research was conducted using 7-Up Bottling Company Plc; Aba. Data relevant to the study were secondary data from past company production records. However, observation of manufacturing processes was done in the course of the study to enhance understanding of production and quality control processes. A random sample was analysed int...
Application of chemicals on weed has been an effective method of weed control. However, this is with problems of persistence and hazardous effects on non-target organisms like arthropods. Common herbicides used in maize fields in Ogbomoso include atrazine, primextra, Lasso/atrazine, diuron pendimethalin, and S-metolachlor. Information on S-metolachlor and Pendimethalin persistence under field situations is inadequate. Therefore, persistence of S-metolachlor and Pendimethalin in maize fiel...
ABSTRACT This is an evaluative study of Inland Waterway Transport Development in Nigeria. Three sets of 5 point Likert Scale questionnaire were crafted for the study for the following categories of respondents; National Inland Water Authority (NIWA) Staff, Ferry Operators and the Inhabitants respectively. Five research questions and five hypotheses were also formed for the study. Data collected were analyzed with descriptive and inferential statistics such as mean procedure and One-way Anov...
ABSTRACT In this research work, the researcher researched on level of manpower planning i.e. if there is adequate manpower planning in the Federal Airports Authority of Nigeria. And the objective of the research work is to know the cause of frequent retrenchment/sack of FAAN workers. As a guide to this study, two propositions/hypothesis were drawn on which the researcher focuses his research work. In the course of the study some related literatures were also reviewed based on this propositio...
Cowpea (Vigna unguiculata (L.) Walp) is one of the most economically and nutritionally important indigenous African grain legumes. It is cultivated in the tropics and sub-tropical regions in Asia and Oceania, the Middle East, southern Europe, Africa, southern USA, and Central and Southern America (Singh et al., 2002). It is an annual crop believed to have originated in Africa (Padulosi and Ng, 1997). Cowpea is well adapted to the dry savanna in the West African sub-region, where it is mo...
ABSTRACT Blockchain technology is emerging and it is seen as the new way to support the needs of individuals and organizations. The blockchain is a distributed public ledger that records information about transactions onto a block which is accessed by all nodes on the network, and the block cannot be altered by any node. It ensures trust and transparency. Literature in the field of Blockchain is very scarce in developing economies in relation to its firm-level adoption and implementation rega...
The Root-Knot Nematode (RKN), Meloidogyne incognita and fungus Botryodiplodia theobromae, are important pests that cause yield losses in cassava and other crops. Chemicals have been used to manage these pests but with undesirable side effects. Information on pathogenicity of M. incognita, its interaction with B. theobromae and its biocontrol in Nigeria is very little. Therefore, pathogenicity of M. incognita on cassava, its interaction with B. theobromae and management with biocontrol ag...
