Effects of anthropogenic activities on soil carbon storage and compactness in coastal plain soil of tropical urban area[ ]


The study on the impact of anthropogenic activities of a tropical urban soil; effects of different land use on bulk density, relative bulk density and their capacity to store carbon were investigated using several key soil physical and chemical properties such as ammonium acetate methods used for determination of cation exchange capacity. Results obtained showed the soil textural class to be sandy in all the land used area. Moisture content and porosity were highest in the automobile servicing area. Bulk density (1.50g/cm3) and relative bulk density (0.82g/cm3) were highest in soil samples from commercial area. Automobile servicing area had the lowest soil pH (5.1), compared to other land use areas, which had it pH ranging from 6.2 – 7.5. The highest value of exchangeable base was obtained also from automobile servicing area compared to other anthropogenic active areas. There is a considerable variation in the total carbon storage from different land uses with the highest carbon storage obtained from automobile servicing area (570.5 g/cm3), this is followed by soil samples from commercial areas (370.0 g/cm3). The lowest value of carbon storage was obtained from institutional area. The major effect of anthropogenic activity is on soil organic matter (OM); therefore the degree of compactness was as a result of the impact on organic matter. Result of this present investigation shows that anthropogenic activities in urban environment affect the compactness and carbon storage of soil.

INHIBITION OF ALUMINUM CORROSION IN 0.5 M SULPHURIC ACID SOLUTIONS BY VELVET TAMARIND – WATER EXTRACT[ ]


The corrosion inhibition of aluminum in 0.5M H2S04 solution in the presence of velvet tamarind (VT) at various concentrations (0.5 - 0.25g/dm3) was studied using weight loss technique at temperature range of 30oC – 50oC. It was found that VT-water extracts acts as a good inhibitor for aluminum corrosion in the sulphuric acid medium. The inhibition efficiency of VT increased with increase in temperature and concentration of the acid. The result shows that velvet tamarind serves as an effective and non-toxic inhibitor of the corrosion of aluminum in H2SO4 solution. The inhibition may be attributed to the adsorption of the active ingredients in VT on aluminum surface. The adsorption fits well into the Langmuir adsorption isotherm.

PERFORMANCE CHARACTERIZATION OF BUILDING INTEGRATED PHOTOVOLTAIC SYSTEMS IN NORTHERN AND SOUTHERN HEMISPHERE LOCATIONS[ ]


This research analyses Building-Integrated Photovoltaic Systems Performance in Northern and Southern Hemisphere Locations. Crystalline silicon BIPV system with peak power of 15KWp was used in the simulation and loss due to wire and inverter was set at 0.0%. The longitude was fixed at 300 and the latitude of the system was varied from 50 to 300 in each hemisphere. Based on the simulation result, it was observed that the annual output energy of BIPV systems increases with the increase in the latitude and systems in northern hemisphere produce higher energy compared to the system in the southern hemisphere. However, the system in the southern hemisphere is more efficient. The result showed that the optimum tilt angle increases with the increase in the latitude and system in the southern hemisphere have a higher optimum tilt angle compared to the system in the northern hemisphere and the hemisphere affects system orientation. The simulation was done using MATLAB and PVGIS.
