Methyl orange was significantly adsorbed by all the activated carbons and the rate increased with time until equilibrium was reached after 24 h. The Freundlich’s adsorption parameters were determined to be 1.71 (plantain peel), 1.20 (car tyre), 1.14 (ram hair), 1.02 (sugar cane chaff) and 1.00 (ram horn). In this study, plantain peel has the highest adsorptive capacity while ram horn has the least. The order of adsorptive capacity is plantain peel>car tyre>ram hair>sugar cane chaff>ram horn. The use of these native materials as adsorbents will lead to cost efficiency and reduce operational cost.

Various researches have been carried out to cub its menace. However, most of the materials are non-biodegradable and require expensive treatment to become an adsorbent. In this study, adsorptive capacities of cost effective raw hard and softwood sawdust were investigated and compared. Soft wood sawdust was found to have better adsorptive capacities. The adsorptive capacities are related to the mesh size of the sawdust, the concentration of the oil, the quantity of the sawdust and the time of contact of the oil and the sawdust. Maximum uptake of the oil by both adsorbents occurred at 120 and 150 minutes for all the results. This study recommends that further research be done on the use of modified softwood sawdust so as to increase its potential as a low cost adsorbent in oil remediation.

Carbohydrates, saponins, flavonoid, phtobatannin were found present. The crude extract of seed husks has no inhibitory activity at minimum inhibitory concentration (MIC) of 2.0mg/cm3 on any of the micro-organisms but the bark has inhibitory activity on Candida albicans, Escherichia coli, Bascillus Subtilis, and plasmodium species. The LC50 of 4.613 and 3.732 were found for the seed husk and bark respectively. The antioxidant characteristics measured as % Ascorbic acid were determined to be 80.54 and 90.70 for the seed husk and bark respectively. This does not compare favourably with a standard antioxidant, ascorbic acid (93.7%).

Constructivists believe that knowledge is not just handed down to the learner from the teacher, but, that knowledge is actively constructed by the learner. New information is consciously built into the cognitive structure of the learner for meaningful learning to take place. This contrasts markedly from rote learning that dwells so much on memorization and recall of facts otherwise known as rote learning. In this paper, research efforts at innovations are highlighted. However, the critical issue is whether or not these efforts have benefited the teaching service. The paper attempts to answer the question whether or not the teachers at the point of implementation are adequately aware of these innovations, and to find ...

The final grain yield at 12% moisture content shows that G/nut cake has the highest yield followed by NPK, soya beans cake, cow dung and control with the least yield. It was observed that though NPK had the largest percentage of Nitrogen and potassium, it did not perform better than Ground nut cake plot. Groundnut cake and soya beans cake compete favourably with conventional NPK fertilizer. Ground nut cake has the lowest ash content (4.13%), followed by soya beans cake (5.42%), NPK (37.43%) and then cow dung (70.79%) with the highest value.
