Research ArticleOpen accessIn the abstractOptimization of Hydrolysis Conditions for the Production of Iron-Binding Peptides from Scad (Decapterus maruadsi) Processing ByproductsWenting Zhang, Yanan Li, Jie Zhang, Guangrong HuangThe scad (Decapterus maruadsi) processing byproduct (SPB) was hydrolyzed by four commercial enzymes, namely, trypsin, flavourzyme, protamex and alcalase, for preparing high Iron-Binding Capacity (IBC) hydrolysate. Alcalase was the best choice for obtaining high IBC hydrolysate from SPB. Response surface methodology using a central-composite design was employed to optimize the enzymatic hydrolysis conditions with alcalase to obtain a maximum hydrolysate … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 17 Oct 2016 · 7,589 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRESPONSE SURFACE METHODOLOGY ANALYSIS OF POLYPHENOL RECOVERY FROM ARTICHOKE WASTEAntonio ZuorroLarge amounts of a solid waste consisting mainly of outer bracts and stems are produced from the industrial processing of artichokes. In this study, the recovery of polyphenols from the two waste components was investigated. Extraction experiments were carried outby an environmentally friendly procedure using aqueous ethanol as solvent. The total polyphenol content, expressed as mg of GAE per g … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 3 Jul 2014 · 7,189 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling and Analysis of MRR, EWR and Surface Roughness in EDM Milling through Response Surface MethodologyA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) has grown over the last few decades from a novelty to a mainstream manufacturing process. Though, EDM process is very demanding but the mechanism of the process is complex and far from completely understood. It is difficult to establish a model that can accurately predict the performance by correlating the process parameters. The optimum … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 9,606 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification of Instabilities of the Chip Formation and It's Prediction Model During End Milling of Medium Carbon Steel (S45C)Md. Anayet U Patwari, A. K.M. Nurul Amin, Waleed FarisProblem statement: Chip shape and size varied widely in machining operations. Undesirable chip formation had a detrimental effect on surface finish, work-piece accuracy, chatter and tool life. Approach: This study included the findings of an experimental study on the instabilities of the chip formation and development of a mathematical model based on statistical approach for the prediction of the instability … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,353 accessesView PDF Cite

Research ArticleOpen accessIn the abstractANN Based Prediction of Effect of Reinforcements on Abrasive Wear Loss and Hardness in a Hybrid MMCP. Sathyabalan, V. Selladurai, P. SakthivelProblem statement: The reinforcements added to an alloy lead to variation in properties. The content and size of the reinforcement influences the properties of composites. Very little research has been carried out in hybrid composites. Work on hybrid LM6 aluminium alloy metal matrix composites (MMC) with flyash and SiC has been initiated here. The effect of the four parameters, size … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,551 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Environmental and Hydraulic Performance of Bio-Composite Revetment BlocksThamer A. Mohamed, Nor A. Alias, Abdul H. Ghazali, Mohd. S. JaafarIt is necessary to develop a concrete revetment block which can cater for environment and at the same time it will be effective in protecting river banks (stabilize the slope of banks) from scouring during flood. In the present study, the environmental and hydraulic performance of the proposed revetment block was evaluated through laboratory and field tests. The tested revetment … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,967 accessesView PDF Cite
