Abstract

The physical and aerodynamic properties of black and white sesame were determined at Moisture Content(MC%) range of 8.5 – 30.6%(d.b).The major, minor, intermediate, arithmetic mean, geometric mean diameters and sphericity, projected area of the two varieties were 2.96 – 3.94mm, 1.47 -2.40mm,0.54 -1.26mm,1.66 – 2.50mm, 0.78 - 3.66mm and 26.53 – 93.45, 1.91 – 42.08mm2 respectively.The increase in MC resulted decrease in true density from 1038.61 – 994.93 kg/mm2 and 1039.61 – 998.47 kg/mm2 for white and black sesame seed respectively.The terminal velocity of white sesame seed ranged from 3.12 – 7.82m/s while black sesame seed ranged from 3.16 – 7.94m/s at MC range of 8.5 – 306% (d.b).The drag coefficient were 3.750.31 and 2.26 – 0.23 for white and black sesame seed respectively as MC ranged from 8.5 – 30.6% (d.b) while Reynold number varied from 2363.9 – 23067.3 and 3401.5 – 15121.6 for white and black sesame seed respectively at MC range of 8.5 - 30.6% (d.b).The properties of sesame seed determined varied significantly with variety and MC.This findings are the prerequisite in the design and selection of sesame seed separating machine. A pneumatic separator can be designed with provision for effective separation of undesired light material with average terminal velocity below 5.17m/s and 5.67m/s for white and black sesame seeds respectively.

Abstract

Aims: The purpose of this project is to find the concentration of heavy metals in the topsoil and the plant around the waste dumpsite from Enugu municipal solid disposal sites. Methodology and Results: There was a collection of soil samples from four designated public municipal solid waste dumpsites in Enugu metropolis. The soil samples were collected at 10m intervals from the centre location point of each dumpsite at a constant depth. The sample collection design include centre (0 m) of the dumpsites, 10, 20, and 30m. However, the control sample was 65m away from the centre of dumpsites at the same depth. Plant samples were taken just at the centre (0m), and control measures were at 65m distance away from each dumpsite. The Goat grasses harvested were taken to the lab to determine and analyse heavy metals intake from the soil. These samples were analysed using atomic absorption spectrophotometer (AA320N) model. On the average, high concentrations of Zn, Fe, Mn, Cu, and Pb found in the soil samples collected at the centre of the dumpsites were 141.70, 121.5, 75.53, 70.33 and 64.53 mg/kg respectively. The results were statistically analysed and had significant effects between the samples (p < 0.05). Conclusion, significance, and impact study: The heavy metals studied were within the acceptable or permissible limit by WHO and FAO. However, the plant intake of zinc at Presidential that was beyond the maximum permissible level of 163.45 mg/kg Zn compared with FAO and WHO standard of 50 mg/kg.
