Research ArticleOpen accessIn the keywordsOptimizing Nano-silver Formation by Fusarium oxysporum PTCC 5115 Employing Response Surface MethodologyM. Karbasian, S. M. Atyabi, S. D. Siadat et al.Fusarium oxysporum was grown in medium containing malt, yeast extracts and glucose on shaker at 25±1°C and180 rpm for 96 h. The mycelia were used to convert silver nitrate solution into nano-silver. The bioconversion was optimized through response surface methodology-central composite design .The factors which affected the process were pH, temperature, agitation rate, concentration of silver nitrate, time of reaction … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,629 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDevelopment of Growth Medium for Centella Asiatica Cell Culture Via Response Surface MethodologyRozita Omar, M. A. Abdullah, M. A. Hasan, M. MarziahThe effects of sucrose, Indole-3-Acetic Acid (IAA) and 6-BenzylAminoPurine (BAP) concentrations on cell growth of Centella asiatica cell suspension culture were studied. The concentrations were designed using Central-composite experimental design and regression analysis was carried out to obtain response surface model describing cell growth for prediction of optimum conditions. Only sucrose as a single factor was positively significant for cell … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStatistical Models for Hardened Properties of Self-Compacting ConcreteArabi N.S. Al Qadi, Kamal Nasharuddin Bin Mustapha, Hashem Al-Mattarneh, Qahir N.S. AL-KadiProblem statement: For predicting workability and hardened properties of Self-Compacting Concrete (SCC) no well known explicit formulation. Approach: Statistical models were carried out to model the influence of key mixture parameter (cement, water to powder ratio, fly ash and super plasticizer) on hardened properties affecting the performance of SCC. Such responses included compressive strength at 3, 7 and 28 days … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,140 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on the Enhancement of Hypoglycemic and Antioxidant Activities of Compound Herbal Tea through Solid-State FermentationQing Liu, Xiaowen Que, Yueping Yang et al.This study utilized Aspergillus niger KY2295 for the Solid-State Fermentation (SSF) of a compound tea made from Cinnamomum cassia bark, Glycyrrhiza glabra, Morus abla L. leaf, and Crataegus oxyacantha L. to enhance its hypoglycemic effects. The fermentation process was optimized using single-factor experiments and a Central Composite Design (CCD), with α-amylase and α-glucosidase inhibitory activities as evaluation indices. Following fermentation, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 20 May 2025 · 5,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization and Molecular Identification of Protease-Producing Thermophilic Bacterial Isolate TUA-26Anthoni Agustien, Mufidhatul Muqarramah, Feskaharny AlamsjahProtease enzymes are used as biocatalysts that can accelerate a reaction. Thermostable enzymes produced by thermophilic bacteria are needed in the industrial field because of their ability to withstand high temperatures. The thermophilic bacterial isolate TUA-26 that produces protease was to analyze the optimum conditions of temperature, pH, agitation, trace elements, carbon sources, and nitrogen sources; the stability of protease … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 6 Apr 2024 · 4,935 accessesView PDFCite
Case ReportOpen accessIn the abstractEarly Management of Non-Syndromic Hypodontia in a Child: Three-Year Follow-UpRoula Berbari, Nahla NassifHypodontia is the congenital absence of few teeth. The early multidisciplinary management of hypodontia assures the reestablishment of the disturbed psychological, aesthetic and oral functions.
