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 ...

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...
Maize (Zea mays L) is the third most important cereal crop in the tropics (CIMMYT, 2004). It is an important grain crop in the world due to its ability to produce economic yields under the marginal production conditions of low soil fertility and management (FAO, 2005). Total world production of maize in 2011 was estimated at 817,110,509 MT. Nigeria‘s share of the production is 9, 180, 270 MT (FAOSTAT, 2011). It is a food crop of economic significance and nutritional importance in the ...

ABSTRACT Activity concentrations of the Naturally Ocurring Radioactive Materials (NORMs) in some bottled water brands were analyzed using gamma spectrometry. 40K activity concentrations were in the range of 3.57-5.47Bq/L, the highest occurring in brand L9. Similarly 232 Th activity concentrations were in the range of 0.30-0.56 Bq/L with the highest occurring in brand L8. 226Ra was identified in eleven brands with the remaining five below detection limit. The highest value (0.53Bq/L) occurr...
