Research ArticleOpen accessIn the abstractAltered Reproduction in Clarias gariepinus Exposed to Industrial EffluentsAdeogun Aina Olubukola, Chukwuka Azubuike VictorProblem statement: Reproductive success is a key factor in determining species survival and the unregulated discharge of industrial effluents into rivers and streams in a developing country like Nigeria, can impair reproductive ability in non-target organisms like fish. Fish, generally accumulate contaminants from their environment in their tissues and these can be transmitted through the yolk lipids to the eggs. … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 21 Feb 2012 · 7,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Evolutionary Algorithmic Approach based Optimal Web Service Selection for Composition with Quality of ServiceD. Palanikkumar, G. KousalyaProblem statement: Web service is a technology that provides flexibility and interconnection between different distributed applications over the Internet and intranets. When a client request cannot be satisfied by any individual service, existing web services can be combined into a composite web service. When there are a large number of Web services available, it is not easy to find an … …Journal of Computer Science, Vol. 8, Issue 4 · 10 Feb 2012 · 6,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractRising Food Insecurity: Dimensions in Farm HouseholdsOkezie Chukwukere Austin, Aloysius Chidi Nwosu, Amir Hussin BaharuddinProblem statement: Nigeria runs the risk of slowing further progress toward the achievement of MDG-1 to eradicate extreme hunger and poverty; the fourth goal, to reduce child mortality since over 30% of child deaths are attributable to malnutrition and the fifth goal relating to reduction in maternal mortality. This study evaluated the manifestation of food insecurity in households in Abia … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 16 Aug 2011 · 8,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Soil Biological Properties of Natural and Planted Forests in the Malaysian Tropical Lowland Dipterocarp ForestDaljit Singh Karam, Arifin Abdu, O. Radziah et al.Problem statement: A study was conducted to evaluate and compare the soil biological properties of a natural forest and an 18-year-old stand of Shorea leprosula in Chikus Forest Reserve, Perak, Malaysia. Approach: Soils were sampled at depths of 0-15 cm (topsoil) and 15-30 cm (subsoil) in six subplots (20×20 m) of natural forest (C1) and of a planted S. leprosula … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 29 Jul 2011 · 7,965 accessesView PDFCite
