Research ArticleOpen accessIn the abstractOptimization of Enzymatic Hydrolysis of Freeze-Dried Sea Cucumber Powder with Response Surface Methodology and Its Antioxidant EvaluationYahui Pang, Jianfeng Sun, Qian LiuIn this study, freeze-dried sea cucumber powder was used as raw material and the preparation processing conditions were studied for hydrolysis of sea cucumber powder with neutral protease using Response Surface Methodology (RSM) to obtain a high concentration of sea cucumber polypeptide. The effects of hydrolysis temperature, pH, enzyme dosage and hydrolysis time on the degree of hydrolysis (DH) were … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 17 Oct 2016 · 7,431 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of Microwave-Assisted Extraction of a Bioherbicide from Canavalia ensiformis LeavesDarlan Ferreira Silva, Eduardo Bessa Azevedo, Maria Olímpia Oliveira RezendeThe objective of this study was to optimize the operational conditions of the Microwave-Assisted Extraction (MAE) of Canavalia ensiformis leaves by Response Surface Methodology (RSM), based on analysis of phenolic compounds obtained from the aqueous extracts. Optimal conditions for MAE were temperature of 100°C, extraction time of 10 min and ramp of temperature of 5 min, using approximately 2 g … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 29 Feb 2016 · 7,612 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of Egg Tofu Formulations Containing Carrageenan, Gum Arabic and Corn Starch by Descriptive Sensory AnalysisMaizura Murad, Aminah Abdullah, Wan Aida Wan MustaphaThe objectives of this study was to determine the effects of carrageenan, gum Arabic and corn starch on the sensory characteristics of egg tofu and to optimize egg tofu formulations using Response Surface Methodology (RSM). A Central Composite Design (CCD) with three factors was used to study the effects of carrageenan (0.1-0.2%), gum Arabic (0.1-1.0%) and corn starch (1.5-2.5%) on … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 11 Mar 2015 · 8,194 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Process Parameters on Electrical Discharge Machined Job Surface IntegrityA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) is the most widely used non conventional machining process for removing material from workpiece by means of a series of repeated electric discharges. Electrical Discharge milling (ED-milling) is an emerging technology where a cylindrical tool electrode follows a programmed path in order to obtain the desired shape of a part. During machining of metals … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,584 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 abstractOptimizing of Trichoderma viride Cultivation in Submerged State FermentationHayyan Ismaeil Al-Taweil, Mohammad Bin Osman, Aidil Abdul Hamid, Wan Mohtar Wan YussofProblems statement: A study in Malaysia had shown a strain of Trichoderma viride was isolated from the soil. Questions were raised whether Trichoderma viride submerged state fermentation affected by parameters and which of them is effective? Approach: To investigate the effects of the submerged state fermentation parameters; concentrations of carbon g L-1; (10, 45 and 80), glucose, nitrogen g L-1; … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 10,076 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSurface Roughness Prediction Model in Machining of Carbon Steel by PCD Coated Cutting ToolsYusuf Sahin, A. Riza MotorcuThe surface roughness model in the turning of AISI 1040 carbon steel was developed in terms of cutting speed, feed rate and depth of cut using response surface methodology. Machining tests were carried out using PVD-coated tools under different cutting conditions. The surface roughness equations of cutting tools when machining the carbon steels were achieved by using the experimental data. … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,964 accessesView PDF Cite
