Research ArticleOpen accessEvery word in the titleA Design Framework for End-of-Life Vehicles Recovery: Optimization of Disassembly Sequence Using Genetic AlgorithmsT. F. Go, D. A. Wahab, M.N. Ab. Rahman, R. RamliProblem statement: It is expected that over the next few years type approval legislation and public awareness will force vehicle manufacturers to identify recovery methods during the design process in order to achieve reuse and recycling targets. Current vehicle design in Malaysia does not sufficiently aid the economic recovery of parts and materials to reach these targets. Approach: This study … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,319 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Backward Recovery Mechanism in Preemptive Utility Accrual Real Time Scheduling AlgorithmIdawaty Ahmad, Muhammad Fauzan OthmanProblem statement: This study proposed a robust algorithm named as Backward Recovery Preemptive Utility Accrual Scheduling (BRPUAS) algorithm that implements the Backward Recovery (BR) mechanism as a fault recovery solution under the existing utility accrual scheduling environment. The problem identified in the TUF/UA scheduling domain is that the existing algorithms only considers the Abortion Recovery (AR) as their fault recovery … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,827 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRecovery of Lead(II) from Aqueous Solutions by Zea mays Tassel BiosorptionCaliphs M. Zvinowanda, Jonathan O. Okonkwo, Nana M. Agyei et al.Problem statement: Major adsorbent materials used in heavy metal ion removal from polluted aqueous streams are expensive and difficult to regenerate. In this study, the possibility of using Zea mays tassel, as an alternative low cost biosorbent material to remediate heavy metal pollution was investigated. Lead (II) was used because of its wide application in industrial products and well documented … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,465 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSustainable Development through Waste Heat RecoveryP. S. Bundela, Vivek ChawlaProblem statement: Waste Heat Recovery (WHR) steam Technology is a proven Technology pioneered by Japanese for cement plant and it is economically viable. Electrical Power can be generated by adopting the latest technology in this field. It used a medium to low temperature (120-350°C) Turbine technology (standard thermal power plants run on steam temp-500°C). Approach: It requires treat exchangers (Hx) … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,401 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUptake and Recovery of Lead by Agarose Gel PolymersAnurag Pandey, Anupam Shukla, Lalitagauri RayProblem statement: The uptake and recovery of lead ions were investigated by using agarose gel polymers. Approach: The experimental results showed that the agarose gel were effective in removing Pb (II) from solution. Biosorption equilibrium was approached within 4 h. Pseudo second-order was applicable to all the sorption data over the entire time range. Results: The sorption data conformed well … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 7,629 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRecovery in Distributed Systems from Transient and Permanent FaultsM. Aliouat, Z. AliouatThe recovery mechanism from transient fault in distributed systems has been intensively studied in the past, but to our best knowledge, none of these studies has been devoted to cope together with transient and permanent hard faults. Our study devoted to recovery processes in a distributed environment in case of hard faults like transient or permanent. The recovery mechanism we … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,854 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntegrated Resource Recovery at East Calcutta Wetland: How Safe is These?Shaon Raychaudhuri, Sayali Salodkar, M. Sudarshan, Ashoke Ranjan ThakurEast Calcutta Wetland (ECW) is an example of wise use of cities solid and liquid waste through integrated resource recovery, mainly for pisciculture, vegetable as well as paddy cultivation and manure production. Amaranthus caudatus, Amaranthus blithum and Spinacia oleracea grown at ECW were analyzed for their accumulation of elements using Energy Dispersive X Ray Fluorescence (EDXRF) and compared to those … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 9,267 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRecovery and Germination of Grass Seeds Ingested by CattleFerhat GökbulakSeeds of bluebunch wheatgrass [Psuedoroegneria spicata (Pursh) A. Love] and Sandberg bluegrass (Poa secunda Presl.) were fed to Holstein heifers in different amounts to investigate the effects of seed feeding level and seed size on the recovery and germinability of passed seed. Animals were fed 60,000, 30,000,15,000, and 7,500 seeds of each species. Passed seeds were recovered from dungcollected daily … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,752 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleChromium (III) Removal and Recovery from Tannery Wastewater by Precipitation ProcessAbass Esmaeili, Alireza Mesdaghi nia, Reza VazirinejadChromium (III) salts are the most widely used chemicals for tanning processes, but 60-70% of total chromium salts reacts with the hides. In the other word, about 30-40% of the chromium amount remains in the solids and liquid wastes (especially spent tanning solutions). Therefore, the removal and recovery of the chromium content of these wastewaters are necessary for environmental protection … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 8,679 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleNASA Sees First in 2018 the Direct Proof of Ozone Hole RecoveryRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuFor the first time, scientists have shown through direct observations of the ozone hole by a satellite instrument, built by NASA's Jet Propulsion Laboratory in Pasadena, California, that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion. Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing human-produced chemicals called Chlorofluorocarbons (CFCs), has resulted … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 22 Jan 2018 · 10,688 accessesView PDFCite
