Research ArticleOpen accessIn the abstractDC Motor Control Predictive ModelsRavinesh Singh, Godfrey C. Onwubolu, Krishnileshwar Singh, Ritnesh RamDC motor speed and position controls are fundamental in vehicles in general and robotics in particular. This study presents a mathematical model for correlating the interactions of some DC motor control parameters such as duty cycle, terminal voltage, frequency and load on some responses such as output current, voltage and speed by means of response surface methodology. For this exercise, … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 7,015 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of Preparation Procedures of Phlorizin-Zn (Ⅱ) Complex and Its Antioxidant Activity Study in vitroYuqing Zhang, Yaping Li, Guorui Yang et al.Flavonoid metal complexes possess more effective antioxidant properties than flavonoids. However, the preparation of the phlorizin-Zn (Ⅱ) complex and its antioxidant activity has not been reported. In this research, the preparation procedures of the phlorizin-Zn (Ⅱ) complex were enhanced using by single factor test and Response Surface Methodology (RSM). The optimal preparation procedures of the phlorizin-Zn (II) complex were as … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 3 Apr 2024 · 4,758 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPhytochemical Profiles and Anti-Diabetic Potential of the Extract of Pueraria lobata Compound Teabags: Preparation and Optimization Infusion ConditionsQing Liu, Wenyue Shi, Futing Xue et al.A Pueraria lobata root compound teabag using Pueraria lobate root, Stigma maydis, and Prunus mume as the main material was prepared in this study, and the brewing technology was optimized using Response Surface Methodology (RSM). The sensory evaluation, total polysaccharide, and phenolic compound content were used as evaluation indicators and the effect of the compound ratio of raw material was … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 26 Nov 2022 · 5,641 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of Purification Technology and Antioxidant Activity of Total Flavonoids from Sea Buckthorn LeavesJiale Shan, Yang Liu, Pu Zhao et al.China is rich in sea buckthorn (Hippophae rhamnoides L.)resources and a large amount of sea buckthorn fruit is used to extract oil andjuice every year. However, Sea Buckthorn Leaves (SBL), which are full offlavonoids, are discarded as waste. To make full use of resources and turn waste into valuables, theoptimal purification process of flavonoids from SBL was studied and theantioxidant … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 27 Aug 2022 · 6,073 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNattokinase Activity Guided Natto Fermentation Process OptimizationXiaojie Ren, Chao Huang, Xin Shan et al.The natto kinase in natto has obvious thrombolytic effect, has the advantages of low cost, small side effects, long half-life and can be taken orally, so it has attracted much attention. At present, the research on natto kinase in our country mainly focuses on the selection of natto fermentation strains, the optimization of gene expression conditions and the exploration of … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Dec 2021 · 7,151 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCharacterization, Antioxidant Activities and Optimization of Preparation Process of a Auricularia Polytricha Polysaccharide-Zinc (II) ComplexXinyi Wu, Xiao Ding, Ze Zhang et al.In our previous work, a novel polysaccharide APP3a from Auricularia polytricha was successfully isolated and purified. Response surface methodology was used to optimize the preparation process of APP3a-Zn on the basis of the single factor experiments. Characterization of APP3a-Zn was carried out and its antioxidant activity was also investigated. The result showed that the best preparation process of APP3a-Zn was … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 25 Mar 2021 · 6,632 accessesView PDFCite
