Research ArticleOpen accessIn the abstractAdsorption Study of Electric Arc Furnace Slag for the Removal of Manganese from SolutionC. L. Beh, Luqman Chuah, Thomas S.Y. Choong et al.Problem statement: Steel making slag from Electric Arc Furnace (EAF) is an abundant by-product in Malaysia steel making industry. It has potential to be used for heavy metal removal from contaminated water or waste water. Approach: The aim of this study was to investigate the characteristic and behavior of manganese removal by using EAF slag for efficient metal removal. The … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractControlling Ammonia Volatilization by Mixing Urea with Humic Acid, Fulvic Acid, Triple Superphosphate and Muriate of PotashShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Inefficient use of inorganic fertilizer such as urea is caused by substantial losses of ammonia when urea is surface-applied. Ammonia losses can be controlled by adding acidic material such as TSP, HA or FA. In order to reduce ammonia loss and retain soil exchangeable ammonium and available nitrate as well as producing complete organic based fertilizer, this study … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 9,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandardization of Metal-Based Herbal MedicinesArun Sudha, V. S. Murty, T. S. ChandraProblem statement: Standardization of herbal drugs is a burning topic in herbal drug industry today. Standardization is difficult because they are usually mixtures of many constituents and the active principle in most cases is unknown. However it is possible to generate a physico-chemical fingerprint for the standardization of these drugs with reference to authentic drugs, for monitoring variation between preparations … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,904 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduction of Ammonia Loss from Urea through Mixing with Humic Acids Isolated from Peat Soil (Saprists)Regis Bernard, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Application of urea as a source of nitrogen fertilizer has an adverse effect on ammoniacal loss to the environment. This study was conducted to reduce ammonia loss from urea by mixing with Humic Acids (HA) isolated from Saprists peat. Approach: The effects of urea amended with four different amounts of humic acids, 0.25, 0.50, 0.75 and 1.00 g … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduction of Ammonia Volatilization through Mixing Urea with Humic and Fulvic Acids isolated from Palm Oil Mill Effluent SludgeShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization from surface-applied urea may be substantial but it is possible to control it by mixing urea with acidic substances such as Humic Acids (HA) and Fulvic Acids (FA). The objective of this study was to compare the effects of urea-HA, urea-FA, urea-acidified (HA+FA) mixtures on ammonia loss, soil pH, soil exchangeable ammonium and available nitrate accumulation … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Quality Komatsuna (Brassica rapa L. nothovar) Production by Using Silicate Minerals Treated Nutrient SolutionSheheli Islam, Kumagai Kazunori, Noriko Takeda, Katsumi IshikawaProblem statement: Good water quality not only produces good crop yield, but also maintains environmental quality and so with plant, animal and human health. Therefore, protecting the quality of water by using non chemical materials is an emerging issue to be solved. Bakuhan seki having additional negative charge were found to have the capacity of improving condition of water while … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,637 accessesView PDFCite
