Biosynthesis of Silver Nanoparticles by Aspergillus terreus: Characterization, Optimization, and Biological Activities

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
In this study, mycelial filtrate of Aspergillus terreus BA6 was used to reduce AgNO3 to form silver nanoparticles (AgNPs). The effect of seven independent variables on the diameter of AgNPs was studied by applying design of experiments (DOE).

FRACTION: A computer program for fractional factorial design [PDF]

open access: yesBehavior Research Methods, Instruments, & Computers, 1988
Factorial designs are used efficiently and effectively to carry out experiments involving multiple independent variables needed to explain complex human behavior. These designs are not feasible, however, when a study requires a large and, in some cases, prohibitive number of measurements on the same subjects (within-subjects designs) or on groups of ...

Optimization and Scale-up of Extracellular b-glucan Production by Ophiocordyceps dipterigena BCC 2073 in Low-Cost Media

open access: yesJournal of Pure and Applied Microbiology, 2017
The optimization of b-glucan production by Ophiocordyceps dipterigena BCC 2073 was carried out. For the three-step optimization performed in 250-mL Erlenmeyer flasks, at the first step, the maximum b-glucan production of 16.48±0.60 g/L was obtained using

Resolution Iv Fractional Factorial Designs

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1969
Summary Fractional factorial designs of resolution IV permit estimation of all the main effects with no aliasing by two-factor interactions. This paper produces a lower bound for the number of observations required for a general fractional factorial design to be of resolution IV. This lower bound agrees with a lower bound obtained by Rao
