Research ArticleOpen accessIn the abstractA Simulation Study of Enhanced Distillation Using Ultrasound Waves for the Separation of Azeotropic MixturesTaha Mahdi, Ammar Emad Al-KawazThe potential of ultrasound waves to enhance distillation system for azeotropic mixture is examined through process flowsheeting using Aspen Plus. Since sonication is not a standard feature in the software library, a mathematical model of the proposed distillation system is developed based on first principles in Aspen Custom Modeler and later exported to Aspen Plus environment for process simulation and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 2 Jan 2018 · 8,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Response Surface Methodology for Optimization of Nickel Adsorption in an Aqueous Solution by ClayNesrine Turki, Nesrine Boujelben, Zaineb Bakari, Jalel BouzidIn this study, Scanning Electron Microscopy (SEM), X-ray diffraction and BET surface area (SBET) methods were employed to characterize the adsorbent. Response Surface Methodology (RSM) was consider as a good method to assess Ni adsorption treatment and Box-Behnken design was used to examine simultaneous the effects of different experimental variables (pH, adsorbent dosage, contact time). Experimental results showed high adsorption … …American Journal of Environmental Sciences, Vol. 17, Issue 5 · 24 Nov 2021 · 6,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of the Strategic Supplementation for Producing Embryos of Native Hartón del Valle HeifersAdrian Rolando Riascos-Vallejos, Julio Jesus Reyes-González, Yolaine Medina-Mesa, Juan Pablo Narvaez-HerreraNutritional imbalances have been confirmed in other breeds, related to energy, proteins and minerals and this affects embryonic development, production of quality. In this regard, the objective of this research was to evaluate the effect of strategic supplementation for the production of embryos in native Hartón del Valle heifers. For that purpose, 18 pure heifers were used, fed with a … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 7 Mar 2021 · 6,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractParameters Affecting the Performance of a Plate Heat Exchanger using the CFDKutay Aydın, Onur Vahip Güler, Ali KeçebaşA plate heat exchanger is a type of heat exchangers that provides more surface area for heat transfer between two fluids. Plate heat exchangers are widely used for heat transfer applications in the industry. In addition, they are now widely used in many applications such as food processing, chemical reaction processes, heating and cooling applications in sectors such as petroleum. … …Energy Research Journal, Vol. 8, Issue 2 · 15 Aug 2017 · 8,678 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodegradation of 2, 4 DichlorophenolTaghreed Al-Khalid, Muftah H. El-NaasThe present study focuses on the optimization of process parameters of the aerobic biodegradation of 2, 4 Dichlorophenol (2, 4 DCP) by a commercial strain of P. putida immobilized in PVA gel matrix, using design of experiments by Response Surface Methodology (RSM). The degradation rates obtained from these experiments were used to evaluate the effects of the main factors and … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 12 Mar 2017 · 7,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Reinforced Concrete Beams and Steel Beams: A Comparative StudyJoel M. Ozimboski, Zacarias M.C. Pravia, Moacir KripkaIn order to support the structural designer with regard to the selection of structural materials, this work presents results obtained from the optimization of reinforced concrete beams and welded “I” steel beams. To achieve this objective, both problems were formulated according to Brazilian standards, considering the cost as objective function and section dimensions as design variables. For the optimization of … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 18 Jun 2020 · 6,600 accessesView PDFCite
