Research ArticleOpen accessIn the keywordsRecycled High-Density Polyethylene and Rice Husk as a Wetted Pad in Evaporative Cooling SystemNitipong Soponpongpipat, Sukum KositchaimongkolProblem statement: The low cost and easy-to-find materials, for being used as wetted pad of evaporative cooling system, are necessary for agriculture. This study, thus, studied the evaporative cooling efficiency and pressure drop of recycled High-Density Polyethylene (HDPE) and rice husk as a wetted pad in evaporative cooling system. Approach: The study was done by establishing the tested wetted pad … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 8,697 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTHROUGHPUT ANALYSIS OF AGGREGATION WITH FRAGMENT RETRANSMISSION PLUS QUALITY OF SERVICE SCHEMETeuku Yuliar Arif, Riri Fitri SariAggregation with Fragment Retransmission (AFR) is a scheme designed for frame transmission to increase efficiency at the MAC layer throughput. AFR provides a higher throughput compare to Distributed Coordination Function (DCF) scheme. However AFR scheme did not has QoS service function when compared to DCF scheme. DCF scheme already has contention-based QoS service using Enhanced Distributed Coordination Function (EDCA) scheme. … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,319 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRemoval and Recovery of Lead from Aqueous Solution by Low Cost MediaLucia Pappalardo, Fawwaz Jumean, Naser AbdoProblem statement: To remove Pb(II) from wastewater using local UAE sand and then to recover the removed Pb(II). Approach: Removal efficiency of Pb(II) from wastewater was investigated using white, yellow and red United Arab Emirates sand with pore sizes < 300 μm. Two methods were employed: batch equilibrium and column filtration. In the batch equilibrium study, the effect of sand … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 6,911 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Study of Soluble Sulfate Reduction by Bacterial Consortia from Varied Regions of IndiaPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriSoluble sulfate contamination in water is observed due to various industrial activities. Chemical means of reduction are available yet the biological approach is the preferred one. Problem statement: The problem addressed in this study was the isolation of efficient sulfate reducing bacterial consortia for bioremediation of soluble sulfate from mining effluent. Approach: The culture based method using the DSMZ specific … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,338 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,895 accessesView PDF Cite
