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.

The importance of sustainable development has started to be acknowledged in Romania as well, once the various pollution sources and the restrictions affecting industrial and agricultural pollution were identified, from an economic and ecological standpoint. Sustainable development represents the need of raising awareness about environmental protection and educating people, and this aspect is reflected by the evolution of communal policies in recent years, policies marked by a shift from an approach based on constraints and sanctions to a higher level of flexibility, based on incentives. The purpose of this paper is to make a recommendation for improving existing policy by making an assessment of economic incentives in order to stimulate farmers to adopt sustainable farming systems of a viable, sustainable agriculture, capable to apply the newest technologies and lead to profit and efficiency, to the economical and organizational consolidation. To analyse the effects of different zone packages on income of farmers and the environment a linear programming model is developed for a typical, 192 ha mixed farm in the Iasi region plain pilot area. The major activities of the farm is keeping dairy cattle, growing fodder (grass, alfalfa, silage maize) and cash crops (winter wheat and maize).

Speciality crops are great alternative cash crops for small scale farmers. Small scale farmers are constantly searching for viable economic crops to grow. We have been conducting applied research on the production and marketing of culinary herbs, oriental vegetables, colored peppers, and muskmelons to name a few. These crops show excellent potential for southern Ohio. Field demonstration, seminars, and surveys were used to gather and disseminate information on these speciality crops. More than 230 people attended our seminars on alternative cash crops. More than 150 people attended our field days. In addition, we had identified many chefs that are willing to purchase from local speciality crop growers. It will be a win-win situation for both chefs and growers. Growers will be able to maximize their profitability while chefs will receive fresh and unique produce. As a result of our research, we were able to show small scale growers what they can grow successfully and how they can market their crops for most profit. These applied research projects received a combined funding of $10000.00 from OSU Extension-Innovative Grant program. These projects are a great way to establish credibility among clients. We would also like to demonstrate how other extension agents can help their clients. A lecture utilizing slides and overhead transparencies will be the format of the seminar.
