Research ArticleOpen accessIn the keywordsResponse Surface Optimized Ultrasonic Assisted Extraction of Total Flavonoids from Walnut Leaves and In Vitro Antibacterial ActivitiesYuanda Song, Aydin Berenjian, Han Wu et al.In this paper, the optimum extraction conditions of total flavonoids extracted from walnut leaves subjected to Ultrasonic Assisted Extraction (UAE) were optimized by Response Surface Methodology (RSM). The mathematical model showed the high coefficient of measurement (R2 = 0.9938) which indicated that this model could be used to guide the response surface methodology. The optimum extraction parameters for extracting flavonoids … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,825 accessesView PDFCite
Case ReportOpen accessIn the keywordsSocial Psychology and Performative Interventions in Human Systems. The GENERATIVE MethodAlessio Nencini, Alessandro Meneghini, Marco PratiThe purpose of this paper is to describe the GENERATIVE method, a methodology for promoting change in human systems (i.e., contexts involving human interactions, such as organizations, communities, institutions). The first part of the paper is focused on the description of the interactionist and constructionist epistemological background adopted. The second is dedicated to the presentation of human systems as socially … …Journal of Social Sciences, Vol. 11, Issue 1 · 29 May 2015 · 7,416 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLinear General Equilibrium Model of Energy Demand and CO2 Emissions Generated By the Andalusian Productive SystemManuel Alejandro Cardenete, Patricia Fuentes Saguar, Clemente PoloIn this study we apply a multiplier decomposition methodology of a linear general equilibrium model based on the regional social accounting matrix to the Andalusian economy. The aim of this methodology is to separate the size of the different effects in terms of energy expenditure and total emissions generated by the whole productive system to satisfy the final demand of … …American Journal of Economics and Business Administration, Vol. 4, Issue 4 · 6 Jul 2013 · 7,079 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFramework for Managing the Very Large Scale Integration Design ProcessSabah Al-Fedaghi, Eman Al-DwaisanProblem statement: The VLSI design cycle was described in terms of successive states and substages; it starts with system specification and ends with packaging. At the next descriptive level, currently known methodologies (e.g., flowchart based, object-oriented based) lack a global conceptual representation suitable for managing the VLSI design process. Technical details were intermixed with tool-dependent and implementation issues such as … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 13 Dec 2011 · 7,491 accessesView PDFCite

Approach: It utilized a quantitative approach using survey based questionnaire as its primary research methodology. Results: The related constructs were: Information quality, system quality and service quality, perceived ease of use, perceived usefulness, security … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExtraction, Partial Identification and Bioactivities of Total Flavonoids from Carex meyeriana KunthHongbiao Wang, Penghui Wang, Xiudong Yang et al.To date, knowledge associated with extraction, chemical constituents and bioactivities of Total Flavonoids from Carex meyeriana Kunth (TFCMK) that remains unclear. Therefore, this paper was designed to optimize the ethanol reflux extraction method by response surface methodology and determine the chemical constituents by Liquid Phase-Mass Spectrometry (HPLC-MS); additionally, the bioactivities including antioxidant, antibacterial and hemolysis test were also explored. The … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 7 Aug 2019 · 7,523 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization of Hydrolysis Conditions for Obtaining Antithrombotic Peptides from Tenebrio Molitor LarvaeFangyuan Chen, Han Jiang, Yini Gan et al.Tenebrio molitor larvae was hydrolyzed by pepsin and trypsin for preparing high antithrombotic activity hydrolysate. The significant variables were selected according to the Plackett-Burman design and further optimized by the Response Surface Methodology (RSM). Four factors, including substrate concentration, pepsin digestion time, pepsin amount and trypsin amount, respectively, influenced significantly on the hydrolysis effectiveness. The best hydrolysis conditions obtained using … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 20 May 2019 · 8,722 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiodegradation 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 · 7,390 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization 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 PDFCite
Research ArticleOpen accessIn the keywordsUsing a Modified Technology Acceptance Model to Evaluate Designing Eight Queens Chess Puzzle GameHussain Mohammad Abu-DalbouhIn the game of chess, the queen can attack any piece that lies on the same row, on the same column, or along a diagonal.
