With fixed optimal values of the cell and substrate feed-batch concentrations, feed-batch flow rate strategies of two types were performed: (1) first, second, and third order polinomial functions with six hours samples were used, and (2) with independent values with six and twelve hours samples.
Effects of O2, CO2 concentrations, feeding rate and [H2O]/[C] ratio on O2/CO2 gasification behavior have been reported (Toshiaki et al. 2009; Toshiaki et al. 2013).
In operation period III, substrate concentrations fed to Rarab and Rgluc were increased to 33.3 mM of arabinose and 27.7 mM of glucose, respectively.
The factors, examined at three levels, included: pH, oil concentration, feed flow velocity, and temperature.
The input properties were water concentration, feed temperature and nanoparticles content, while pervaporation separation index (PSI) was output.
R (H2O/surfactant) value, h (H2O/TEOT) value, ammonia concentration, feed rate, and reaction temperature were chosen as significant parameters.
Several factors might interfere with the electrospinning process, such as emulsion concentration, feed rate, applied voltage, and tip to collector distance.
The design can be adapted to changes in design constraints or the variations in feed concentration, feed volume, or material properties.
