The data were made up mainly of the cost of disassembly, replacement and reconditioning of parts or units.

OHWORORIOLE et al (1988) reported a simple manual rig that worked on the principle of peel/flesh separation through compression followed by peel removal with knives. The principle looked promising for further research. However, before the design could commence, experiments had to be carried out on the physical properties of the cassava tuber. This resulted in the characterisation of the cassava tuber (Adetan et al, 2003).

INTENDED cylinders separate grains based on differences in shape while inclined drapers effect separation on the basis of differences in surface textures of the particles. In contrast, the electromagnetic separator effects separation based on differences in the electrical properties of the grains and the foreign matter.

When last weekend the leader of the Islamist group Boko Haram, Abubakar Shekau, said Gwoza in Borno State had been declared an ‘Islamic Caliphate’, following its alleged capture, the military was quick to deny the claim.
