Development of a prototype inverter powered baking oven was carried out and performance was evaluated to determine its efficiency. The oven was designed and fabricated with an outer dimension (506 mm length x 506 mm width x 506 mm height) made up of mild steel and inner dimension (436 mm length x 436 mm width x 436 mm height) made up of stainless steel and used fiber glass as an insulator. The materials for fabrications were locally sourced and served as alternative for baking, roasting or boiling using electrical recharged power in case of power failure. The prototype inverter baking oven operates on the principle of electrical resistance and 0.147?/W was obtained as the resistance of the heating element. The performance evaluation revealed the baking efficiency of the oven to be 94.29 %, 75 % and 66.7 % for bread, plantain and fish respectively, the maximum temperature of 160?C, 180?C and 200?C were recorded. Capacity of the baking oven was determined to be 6 loaves of bread per tray/batch. With practical determination and comparison made with other work, a prototype inverter powered baking oven can be adopted for domestic and industrial purpose depending on the production plans and the layout.

This work compared the effect of fillers on the mechanical properties of recycled low-density polyethylene composites under non-weathered and weathered conditions. Pure water sachet wastes, glass wastes were sourced from dump-site at Obafemi Awolowo University, Ile-Ife, Nigeria, while the talc was sourced from Lagere, Ile-Ife, Nigeria. Recycling of plastic bags (low-density polyethylene) and the preparation of recycled low-density polyethylene (RLDPE)/glass, RLDPE/ talc and RLDPE/glass/talc composites were carried out using a furnace at compositions of 0 to 40% in steps of 10% by weight. The mixtures were then poured into hand-laid mould for tensile, impact and hardness tests. The samples were divided into two groups; one group was subjected to natural weathering conditions. The results of mechanical tests carried out were subjected to a paired t-test. The study concluded that there was no significant difference between the non-weathered and weathered samples. This implies that both talc and glass were able to reinforce recycled low density polyethylene (RLDPE) under both conditions and can help resist degradation.
