It appears that their various attempts to get developed have failed to yield results as African countries are still far from being developed. The basic questions on this researcher’s mind are: what exactly is responsible for Africa’s slow development and what is the way forward? The researcher is well aware that there are many credible answers to these questions but is convinced that the slow growth of science and technology in the continent is largely responsible for her development plight. This research therefore, employing the philosophical methodology of criticism, argumentation and analysis, and relying majorly on secondary sources of data, attempted to show that the development of any nation largely hinges on its advance in science and technology. The paper, in the light of this, reiterated the need to develop science and technology in the continent. It recommended as ways of repositioning science/technology in Africa: a change in Africa’s cultural mindset, making efforts to stop brain drain and ensuring technology transfer from developed countries amongst other recommendations.</p> <div class="SnapLinksContainer" style="margin-left: 0px; margin-top: 0px; display: none;"> <div class="SL_SelectionRect">&nbsp;</div> <!-- Used for easily cloning the properly namespaced rect --></div> 2018-09-03T00:00:00+00:00 ##submission.copyrightStatement## The boomerang effect of environmental degradation: The way forward 2018-09-11T08:09:14+00:00 Bisong Peter Bisong <p>Any action of man has a boomerang effect. Positive actions have positive effects and negative actions have negative effects. Thus, any action done in the environment has a corresponding effect on humans. When the environment is handled with care and respect, it would provide the needs of humans in appropriate measures. However, when the environment is mishandled, it would produce disastrous consequences like floods, acid rain, global warming, increase in ocean acidity, ozone depletion et cetera. These consequences that accrue from our wrong use of the environment would render the environment incapable of satisfying the teeming needs of man – this work wishes to raise the consciousness of all to this fact. The work advises man to order his actions in such a way that the complementary horizon we share with nonhuman nature will be maintained. Every action that is geared towards harming the other (environment) would bounce back on the actor, because we share the same complementary horizon, which must be maintained, if we all hope to have a meaningful existence. This is necessary because development cannot be sustained if the environment is not preserved. It means Africa cannot hope to attain the height it guns for if appropriate actions are not taken to sustain the environment.</p> <div class="SnapLinksContainer" style="margin-left: 0px; margin-top: 0px; display: none;"> <div class="SL_SelectionRect" style="top: 26px; left: 21px; height: 0px; width: 0px;">&nbsp;</div> <!-- Used for easily cloning the properly namespaced rect --></div> 2018-09-04T00:00:00+00:00 ##submission.copyrightStatement## Comparative Studies on Phytochemical Screening and Antioxidant Activity of Zehneria scabra (Linn. F) Soud and Zehneria maysorensis (Wight & Arn.) Leaves 2018-09-11T08:09:14+00:00 Vishnu Kumar S. Pugalenthi M <p>The present study was carried out to evaluate antioxidant activity of petroleum ether, methanol and water extracts of <em>Zehneria scabra </em>and <em>Zehneria maysorensis. </em>The preliminary phytochemical tests showed the presence of alkaloid, tannin, saponins, phenol, flavonol glycosides, cardiac glycosides, phytosterol, fixed oils and fats, gums and mucilage. A dose dependent antioxidant activity was observed in case of extracts. Phenolics (36.6 g gallic acid equivalents (GAE)/100 g extract), tannin (21.6 g GAE/100 g extract), and flavonoid content (67.5 g rutin equivalents/100g extract) were found to be highest in acetone extract. <em>Zehneria scabra</em>and <em>Zehneria maysorensis</em> both methanol extract showed maximum antioxidant activity in DPPH (21.6 and 40.87 µg/mL), ABTS cation radical scavenging activity (66923.6 and 71958.3µmol TE/g extract). Hence, <em>Zehneria </em>can be a valuable source for antioxidant and seemed to be applicable in medicine.</p> 2018-09-04T00:00:00+00:00 ##submission.copyrightStatement##
