Research ArticleOpen accessIn the abstractEffect of N and K Fertilizers on Nutrient Leaching and Groundwater Quality under Mature Oil Palm in Sabah during the Monsoon PeriodPetronella G. Ah Tung, Mohd Kamil Yusoff, Nik Muhamad Majid et al.Problem statement: The oil palms are mainly grown in the humid tropics with high rainfall. Soluble Nitrogen (N) and Potassium (K) fertilizers are commonly required by the oil palm plantations to maximize palm productivity due to the highly weathered soils with low fertility. Thus, leaching losses of N and K nutrients may be unavoidable and these nutrients may move further … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 10,143 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,167 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing the Urea-N Use Efficiency in Maize (Zea mays) Cultivation on Acid Soils using Urea Amended with Zeolite and TSPOsumanu Haruna Ahmed, Aminuddin Hussin, Husni Mohd Hanif Ahmad et al.Problem Statement: Ammonia loss significantly reduces urea-N use efficiency in crop production. Efforts to reduce ammonia loss are laboratory oriented, as such limited in reflecting actual field conditions. This paper reports the effects of urea amended with triple superphosphate (TSP) and zeolite (Clinoptilolite) on soil pH, soil nitrate, soil exchangeable ammonium, dry matter production, N uptake, fresh cob production and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 8,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Manganese Uptake by Wetland PlantsA.E. Ghaly, A. Snow, M. KamalThe aim of this study was to assess the kinetics of Mn removal by broad-leaved cattail, soft stem bulrush, soft rush and wool grass plants from contaminated wastewater under laboratory conditions. The approach used was based on a first order kinetic model which depended on the initial heavy metal concentration in the wastewater and allowed for the evaluation of the … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Iron Uptake by Wetland PlantsA.E. Ghaly, A. Snow, M. KamalThe aim of this study was to assess the kinetics of Fe removal by broad-leaved cattail, soft stem bulrush, soft rush and wool grass plants from contaminated wastewater under laboratory conditions. The approach used was based on a first order kinetic model which allowed for the evaluation of the specific metal uptake rate and the maximum accumulation of the metal … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractTraditional Aquaculture Practice at East Calcutta Wetland: The Safety AssessmentS. Raychaudhuri, M. Mishra, S. Salodkar et al.The current study is on East Calcutta Wetland (ECW) which is a model for multi-use resource recovery system with activities like pisciculture and agriculture. The entire city's soluble waste is disposed into the raw sewage canals which finally drains into the shallow, flat bottom fish ponds called Bheri. These sewage fed fisheries act simultaneously for the purification process like removal … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstablishment and Evaluation of the Vegetative Community in A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC.C. Galbrand, A.M. Snow, A.E. Ghaly, R. CôtéA surface flow constructed wetland, designed to curve in a kidney shape in order to increase the length to width ratio to 5:1 was used to treat runoff from an industrial park. A natural wetland system located approximately 200 m downstream of the constructed wetland was selected to act as the vegetative community model for the constructed wetland. The selected … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential of Agarose for Biosorption of Cu(II) In Aqueous SystemAnurag Pandey, Debabrata Bera, Anupam Shukla, Lalitagauri RayThe ability of agarose gel as an adsorbent for Cu(II) ions in aqueous solution was studied. The experiments were done as batch processes. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, Cu(II) ion concentration, adsorbent dose, temperature and pH. Adsorption equilibrium of agarose gel was reached within 4 h for agarose gel when … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 6,829 accessesView PDFCite
Research ArticleOpen accessIn the abstractDietary supplementation with Cyperus esculentus L (tiger nut) tubers attenuated atherosclerotic lesion in apolipoprotein E knockout mouse associated with inhibition of inflammatory cell responsesMohamed L. Salem, Mohsen Zommara, K. ImaizumiAtherosclerosis is a pathological process, where recruitment of mononuclear cells results in the growth of fibro-fatty plaques. Apolipoprotein E (ApoE) is a legend for the uptake of lipoproteins, and deficiency of ApoE leads to the accumulation of low-density lipoprotein. Utilizing ApoE-/- mouse, which spontaneously develop atherosclerosis on low-fat chow diets, the present study showed that feeding these mice on a … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 10,471 accessesView PDFCite
