Research ArticleOpen accessIn the keywordsToxicity of Industrial Wastewater Acting Singly or in Joint-Ratios on Clarias gariepinusAina Olubukola Adeogun, Azubuike Victor ChukwukaFreshwater ecosystems were the most vulnerable to pollution due to their easy accessibility for disposal of wastewaters leading to deterioration of water quality. Ona river, Ibadan, Nigeria is part of a dense network of inland watercourses emptying into the Lagos lagoon and receives industrial effluents from a food and beverage industry. The single and joint-action toxicity of effluents from these … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 7,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Bio-based Polyurethane PolymersJahangir Emrani, Ramazan Benrashid, Shahrzad Mohtarami et al.This paper describes the development of new biobased Polyurethanes (PU) starting from swine manure bio-resin and diisocyanates. The bio-resin is produced from swine manure via a hydrothermal process. For sustainability, today, many PUs in new specialized applications, are biobased. In this study, different commercial diisocyanates including MDI, Desmodur W, Desmodur H and Demodur I and swine manure, which is an … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 28 Nov 2018 · 8,361 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing of Box-Benken Method to Predict the Compressive Strength of Self-Compacting Concrete Containing Wadi Musa Bentonite, JordanArabi N.S. AL Qadi, Mahmoud B.A. ALhasanat, Ahmad AL Dahamsheh, Sleiman AL ZaiydneenThis research presents application of Box-benken design method to develop model for predicting 28 days compressive strength of Self-Compacting Concrete (SCC) with partial replacement of cement with Wadi Musa bentonite, Jordan for which the data of 15 mixtureshave been tested and preparedat the laboratory of AL Hussien Bin Talal University. The use of Bentonite as filler materials in self-compacting concrete … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 May 2016 · 8,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractUSE OF CRUMB RUBBER TO IMPROVE THERMAL EFFICIENCY OF CEMENT-BASED MATERIALSAshraf Fadiel, Fouad Al Rifaie, Taher Abu-Lebdeh, Ellie FiniMotivated by the tremendous trend toward green environment and to reduce the effect of scrap tires on the environment and human health, this research is an attempt to find a practical and environmentally sound solution of the problem of scrap tires by developing a light weight with low thermal conductivity composite construction materials using waste tires. A few literatures may … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 14 Mar 2014 · 12,197 accessesView PDFCite
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 · 7,706 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStatistical Models for Hardened Properties of Self-Compacting ConcreteArabi N.S. Al Qadi, Kamal Nasharuddin Bin Mustapha, Hashem Al-Mattarneh, Qahir N.S. AL-KadiProblem statement: For predicting workability and hardened properties of Self-Compacting Concrete (SCC) no well known explicit formulation. Approach: Statistical models were carried out to model the influence of key mixture parameter (cement, water to powder ratio, fly ash and super plasticizer) on hardened properties affecting the performance of SCC. Such responses included compressive strength at 3, 7 and 28 days … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,140 accessesView PDFCite
