ABSTRACT This study evaluated the Impact of Devegetation on Soil environment of Nnewi North LGA in South East- Nigeria. It is caused by increasing demand for land with its consequences on disruption of soil ecology, climate change, breakdown of nutrient cycle and increase in soil erosion, siltation of dams and reservoirs, destruction of wildlife habitats, and loss of plant and genetic diversity. Soil samples for analysis were obtained in the study area from depth 0-15 cm, 15- 30 cm and 30...
ABSTRACT Agricultural waste has been of major source of environmental pollution and its utilization and conversion to renewable energy will discourage possible consequences associated with its discharge in the environment. This study was targeted at the conversion of waste to fish feed. Samples were collected in quantities from dumpsites abattoirs, market places using 20kg polypropylene bags and transported to the production sites. Plantain peels meal, banana peel meal, cassava peel ...
ABSTRACT This study examines and analyses the salient factors that constrain work schedule performance and their contributions to the level of project time overrun in construction industries in Nigeria. The realization of project work schedule objectives is usually not achieved with certainly due to myriads of constraining factors encountered during the implementation stage of project life cycle. The survey method of research design was adopted. The primary data used in the study was ...
ABSTRACT This thesis investigates the nature and variability of climate change-induced rainfall over Awka, Anambra state. Time series of annual rainfall for Awka, Anambra state was analysed to reveal shifts in rainfall pattern occasioned by ongoing climate change. Past rainfall data over four decades (1975-2014) were collected for the study area for analysis. The series exhibited shifts in bimodal rainfall pattern during annual analysis, however, decadal analysis showed no significant shi...
ABSTRACT This research work investigated trade openness and manufacturing sector growth: An Empirical Analysis for Nigeria (1982-2015). The study was necessitated by the important role which trade openness plays in growing the manufacturing sector of any economy. The study made use of secondary data in its analysis. Four explanatory variables (trade openness growth, investment growth, production index growth and exchange rate growth) were specified based on theoretical underpinnings and ...
ABSTRACT The potentials of Moringa oleifera seeds and Aluminium Sulphate as coagulants for the treatment of water samples from Usuma River Abuja was carried out. The physicochemical parameters investigated were the Turbidity (in NTU), Total Dissolved Solids (in mg/l), Conductivity (in μS), and Salinity (in ppm). For the water treatment with Alum, the standard municipal water treatment dosing of 360 mg/l was used. For the treatment with the natural coagulant, there was need to determine t...
ABSTRACT This study attempts to analyze the Impact of the implementation of the Cabotage law on the Maritime Industry in Nigeria. Taking the Nigerian Maritime Administration and Safety Agency (NIMASA) as the case study, the study x-rayed the level of enforcement of the Cabotage by NIMASA as a Maritime regulatory body in Nigeria. More emphasis was laid on the benefits accruable to stakeholders of coastal trade. A Comparative analysis is carried between few selected countries and Nigeria. W...
ABSTRACT This study was carried to assess the effectiveness of clean-up sites impacted by oil spill at Kpean and Buan communities in Khana Local Government Area of Rivers State. Soil samples were collected at 0-15 and 15-39cm depths from three sampling sites(two impacted and one control sites) with soil auger and analyzed for pH, TOC, TPH, Zn, Cd, Cd, HB and HDB using standard methods. The concentrations of pH, TOC, TPH varied between 5.08 – 6.86 (6.04 + 0.24), 0.32 – 2.62 (1.18 + 0.3...
ABSTRACT Pollution of rivers, had become a major problem facing our society today. This often occurs as a result of waste washed into Rivers as in the case with Nworie River in Owerri metropolis. In order to assess the water quality of Nworie River, water samples were collected at three locations namely point A (upstream) serves as control, point B (midstream) and point C(downstream). The samples were properly analyzed with focus on some physical and chemical parameters. The result of th...
ABSTRACT This study assessed the impact of the port concession adopted in Nigerian ports in 2006. The study is necessary in order to ascertain the impact of the model based on a painstaking study. Data was collected from the abstract of ports statistics on three major variables namely, cargo throughput, average berth occupancy and average turnaround time, from 1995 to 2012. The data was analysed using Mann- Whitney Wilcoxon (WWW) Test. The result shows that on the average, all the indices...
Abstract This study undertook a comparative analysis of direct government finance and public private partnership (PP) option for healthcare infrastructure development. The objective is to assess the cost, time and financing leverage effects of the two financing options. The Federal Medical Centre (FMC) Owerri was used as study location. Two identical building projects: Ward II funded through PPP and Ward 10 funded through direct government financing was used as case studies. A combination...
ABSTRACT This study examined the physicochemical and bacteriological analysis of ground water quality in Federal University of Technology, Owerri (FUTO) and its neigbouring Communities. Groundwater samples were collected, two from 4 different locations and were immediately transported to the laboratory for standard analyses. pH ranged between 5.24-4.71; EC (40-11.00 μS/cm); sulphate (5.94-1.58mg/L); Total Hardness (44.30-12.40mg/L); Mg (8.79- 1.20mg/L); Cl- (8.10-5.00mg/L); nitrate (0.00...
ABSTRACT The study investigated heavy metal levels in the Bonny River. Water and sediment samples, collected at four major sites selected along the river course, were analyzed for heavy metals (Pb, Zn, Ni, Cd, Cu, and As) using standard methods. The pH in water was higher (7.94) than in sediment and EPA standards (6.5-7.5) and in water; it was lower than the recommended values for EPA and WHO. Descriptive statistics and Pearson correlation were used to analyze data at PAs>Cu>Pb>Cr>Cd>Ni. ...
