The sub-family Phthiriinae (Bombyliidae: Diptera) in tropical Africa

The article sets out to unveil the challenge of drugs in Njega and Kamuiru secondary schools of Kenya. With drug challenge becoming the single major threat to the entire education system in tropical Africa, the sampling of the two schools will help in opening up the matter for decisive action by the relevant stakeholders. Methodologically, the article begins by theorizing the issues regarding drug menace as it wonders: Why do teens engage in this vice? What are the practical effects of drug abuse? And more importantly, what can we do to arrest the challenge? Even though the article has not given the final solution on how it can comprehensively be tackled, it has however opened up possibilities that can lead to the final onslaught. The materials in this article are gathered via oral interviews, some selected readings, participant observation especially through visiting the specific sites, and through critical analysis.

IntroductionThis essay provides an explanation of the dynamics of the interactionbetween Islam and politics by placing emphasis on the role played byMuslims in the collision of traditionalism and British rule as colonialismtook root in Lagos. The focus is on the development of a political schismwithin the nascent Muslim community of metropolitan Lagos at the startof the twentieth century up until the end of the 1940s. It highlights therole of Islam in an emerging urban settlement experiencing rapid transformationfrom a purely rural and traditional center into a colonial urbancenter. The essay is located within the broader issues of urban change andtransition in twentieth-century tropical Africa. Three major developments(viz: the central mosque crisis, the Eleko affair, and the Oluwa land case)are used as the vehicles through which the objectives of the essay areachieved.The introduction of Islam into Lagos has been studied by T. G. O.Gbadamosi as part of the history of Islam in southwestern Nigeria. Thisepic study does not pay specific attention to Lagos, devoted as it is to thegrowth of Islam in a far-flung territory like the whole of modem southwesternNigeria. His contribution to a collection of essays on the historyof Lagos curiously leaves out Islam’s phenomenal impact on Lagosianpolitics during the first half of the twentieth century. In an attempt to fillthis gap, Hakeem Danmole’s essay also stops short of appreciating the fundamentallink between the process of urbanization, symbolized in this caseby colonial rule, and the vanguard role played by Muslims in the inevitableclash of tradition and colonial rule in Lagos between 1900 and 1950.

Free radicals and reactive species are widely believed to contribute to the development of several diseases by causing oxidative stress and eventually oxidative. Vernonia amygdalina (Astereacea) is a small shrub or tree between 1 and 5m high growing throughout tropical Africa. Plants are generally known as bitter leaves is well cultivated and is a general market for merchandise in several countries. The purpose of this study was to determine the antioxidant activity of hexane fraction from ethanol extract od Frican leaves (Vernonia amygdalina Del.). The method used in this study was the DPPH (1,1-Diphenil-2-Picrylhydrazyl) method. The result of phytochemical screening showed that ethanolic extract of African leaves contained a composition of secondary metabolites of alkaloids, flavonoids, tannins, steroids/triterpenoids and saponins. The antioxidant activity of the extract of n-hexane fraction was classified as very weak with an IC50 value of 317.98 ppm.
