Research ArticleOpen accessPhrase in the titleEffect of Mixing on the Biological Degradation of Toluene under Aerobic ConditionsAbdel E. Ghaly, D.G. Rushton, K. MartinellThe effectiveness of in-vessel bioremediation in reducing the concentration of toluene in contaminated soil under continuous and intermittent mixing conditions using invessel composting system. The results showed that there was a startup period (60 h) during which the average temperature rose from 21 to 32 and 40°C (and then remained constant) for the bioreactors with continuous and intermittent mixing, respectively. … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,497 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleNitrification of Urea and Assimilation of Nitrate in Saturated Soils Under Aerobic ConditionsV. V. Ramakrishnan, A. E. GhalyThe aim of this study was to investigate nitrification activity of urea and the assimilation of nitrate in a well aerated soil using perfusion technique with addition of glucose as an energy and carbon source. In this study, urea was rapidly nitrified by the bacteria in the saturated soil but its course of transformation to NO3 was not linear. There … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 6 Nov 2013 · 8,415 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTreatment of Landfill Leachate using Limestone/Sandstone Filters Under Aerobic Batch ConditionsAbdel E. Ghaly, M.A. Kamal, N.S. Mahmoud, R. CoteThe suitability of a passive technology, consisting of filters composed of a mixture of limestone and sandstone rocks, for the treatment of landfill leachates containing 6.6 mg Lˉ1 iron and 1.8 mg Lˉ1 manganese were investigated. The limestone and the limestone/sandstone filters successfully removed iron from the prepared solutions. The filters removed on average a minimum of 97.60% of the … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,066 accessesView PDFCite
Research ArticleOpen accessIn the keywordsResponses of Grain Yield and Nutrient Accumulation to Water and Foliar Fertilizer Management in Upland and Wetland Rice VarietiesNatdanai Juntakad, Sittichai Lordkaew, Sansanee Jamjod, Chanakan Prom-u-thaiThis study evaluated the effects of water and fertilizer managements on grain yield and nutrient accumulation in upland and wetland rice varieties. The two rice varieties representing upland (KH CMU) and wetland (CNT1) ecotypes were grown in different water conditions and fertilizer managements. The interaction between variety and water condition had significantly affected on grain yield and straw dry weight. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 May 2018 · 8,356 accessesView PDFCite
Research ArticleOpen accessIn the abstractBacteriological Assessment of Rainbow Trout (Oncorhynchus mykiss) Subjected to Low-Temperature StorageRomán Alejandro Téllez-Cortez, Ángel Ruyan García-Hurtado, Mayra Diaz-Ramírez et al.Fish is a food with high nutritional value and an essential part of the human diet. However, this food is highly perishable and poses a health risk when contaminated along the food chain, requiring preservation processes at low temperatures. Trout (Oncorhynchus mykiss) is one of the most widely produced and marketed fish species for human consumption worldwide, through products such … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 31 Jul 2026 · 1,008 accessesView PDFCite
