Research ArticleOpen accessIn the keywordsMaximizing Fungal Growth in State-of-the-Art Tray Solid-State Fermenter: Aeration Strategies Optimized for Enhanced PerformanceMusaalbakri Abdul Manan, Colin WebbThis study introduced a tray fermenter, featuring eight layers of squared perforated trays, specifically designed for solid-state fermentation applications. It is named the multi-layer squared tray solid-state fermenter. The fermenter employs two aeration strategies with varying air flow rates to optimize fungal growth. Firstly, sterilized moistened air at 8 L/min flows from the bottom through the perforated trays. Secondly, a … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 9 Apr 2024 · 6,453 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsComparison of Compertz and Logistic Models in Estimating the Growth of Leptin-Deficient (ob/ob) Mice and Wild-Type Mice Fed an In-House Prepared High-Fat DietAh Reum Son, Hyunwoong Jo, Kyu Ree Park, Beob Gyun KimThis experiment was conducted to growth curve models for leptin-deficient (ob/ob) and wild-type mice fed a meal-form High-Fat (HF) diet prepared in-house for over 120 weeks. Two hundred and twenty-four sets of Body Weight (BW) and age data were collected from ob/ob mice and 485 sets of data were collected from wild-type mice. All animals had free access to the … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 1 · 19 Jan 2019 · 7,682 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison of Nonlinear Models for Dry Matter Yield of Brachiaria Hybrid cv Cayman in Drought Season by BootstrappingDanny Villegas Rivas, Nora Valbuena Torres, Manuel Milla Pino et al.The dynamics of biomass accumulation at different seasons of the year is of vital importance in the production of a forage species. In this study nonlinear models (logistic and gompertz) to describe growth dynamics of plants based on dry matter yield of Brachiaria hybrid Cayman at different interval between cuts in drought season were used. Results for logistic and gompertz … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 15 Mar 2021 · 6,640 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNonlinear Growth Models for Modeling Oil Palm Yield GrowthAzme Khamis, Zuhaimy Ismail, khalid Haron, Ahmad Tarmizi MohammedThis study provided the basic needs of parameters estimation for nonlinear growth model such as partial derivatives of each model, determination of initial values for each parameter and statistical tests of industrial usage. Twelve nonlinear growth models and its partial derivatives for oil palm yield growth are presented in this study. The parameters are estimated using the Marquardt iterative method … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 15,101 accessesView PDF Cite
