ABSTRACT The water quality of the Imo River in Oyigbo local government area was ascertained using standard methods in this research. The important physicochemical characteristics of the river were investigated during the wet season of 2013 at six sampling locations. In situ measurements were made for water temperature, salinity, turbidity, dissolved oxygen (DO), biological oxygen demand (BOD), etc using the HORIBA U-10 water quality checker. The total dissolved solids and total soluble...
ABSTRACT Leaf extract of Anthocleista djalonensis and Viscum album were investigate as inexpensive and environmentally friendly corrosion inhibitors for mild steel in 0.5 M H2SO4 and 3.5% NaCl was investigated by weight loss and potentiodynamic polarization techniques. The results revealed that Anthocleista djalonensis and Viscum album inhibited the corrosion reaction and the inhibition efficiency increased with increasing concentration of extracts but decreased with prolonged exposure ti...
ABSTRACT The quality of groundwater impacted by a waste dumpsite in Eneka, Rivers State was studied using temporal approach. Groundwater samples were collected and analyzed for 27 parameters using standard methods. Water samples were collected with 250mL plastic containers from seven sampling boreholes. Samples for heavy metals were fixed with concentrated HNO3 in the ratio of 2:500. The descriptive statistics, one-way ANOVA, means plots, variation plots and student’s t-test were us...
ABSTRACT The inadequacies of Nigerian ports toward the delivery of quality services such as good infrastructure, cargo handling, vessel quick turn round time, corrupt and fraudulent tendencies has given rise to privatization and concession since this practices can brief about the required level of efficiency and effectiveness when compared with international standards. This research work would enable us ascertain the effects of concessioning of Nigeria seaports. And also evaluate the viab...
ABSTRACT This study investigated the trace metal contamination of two fish speciesClariasgariepinusandOreochromisniloticus obtained from the Choba axis (Downstream) and Aluu axis (Upstream) of New Calabar River in Rivers State. The fishes were dried, ashed and analysed for trace metals such as Zn, Pb, Cd and Cu using the atomic absorption spectrophotometer of model Unican Solar 969.The results obtained showed that Pb values ranged from 0.097 to 0.655 mg/kg with the highest obtained inOreo...
ABSTRACT This study involved proximate analyses of four borehole water samples within an average distance of 30.25m from municipal solid waste dumpsites in Obio-Akpor Local Government Area of Rivers State, an area commonly known as Greater Port Harcourt or Port Harcourt Metropolis. Water quality and analyses of some bio-physico-chemical variables (pH, total suspended solids (TSS), total dissolved solids (TDS), colour, total coliform, faecal coliforms and some water borne pathogens) were c...
ABSTRACT Materials Management in the Construction Industry in Imo State have been investigated. In order to reduce wastage of construction materials, the study focused on Success Level in Achieving Effective Materials Management as the Dependent Variable (Y) by introducing five Independent Variables (X1 to X5) thus (X1) Management of Materials; (X2) Skilled Professionals; (X3) Control of Materials; (X4) Inventory Build-up and (X5) Motivation of workers. Three indigenous construction compa...
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...
