In the simulated scenarios, the boiler size was based on the mass flow feed rate of solids to the boiler, and the turbine system was modified to the steam requirement as the 2G process.
The feed rate of the culture was controlled by the rate of base consumption (see Methods).
Lactose was fed to the fermentor after 45 h at a rate that maintained the rate of base (NH4OH) consumption at around 0.012 0.014 ml l-1 min. As long as the feed rate of lactose was below 30 mg h-1 g-1 DW, acs1 mRNA level continued to increase, but it decreased rapidly after the feed rate increased above this value, even though the residual lactose concentration in the medium remained zero.
Based on a feeding rate of 1%% of the organism's weight per day, assuming the same fugacity capacity of the organism and its diet for the studied chemical and an uptake efficiency from food of 100%%, an EL 0.5 of 70 days as a trigger value for high bioaccumulation was suggested (adjustments for lower efficiencies can be made, [15]).
The study was based on a 60 m3 Tilapia system with average daily feed rates of 45 kg using a 40% protein feed and an average biomass of 6750 kg.
Pressures in the larger unit (based on U-Gas design) were up to 14.2 bar, and feed rates of the feedstock were a maximum of 720 kg/h.
Discrete and compositionally graded dual materials based on SS316 and IN625 alloys were made using LENS™ process by layer wise deposition, controlling feed rates of individual alloy powders.

A factorial experimental design based on temperature, feed rate and addition of "working fluid" (WF; fatty acid ethyl esters) was used to model a short-path distillation process applied for removal of persistent organic pollutants (POPs) in fish oil.
Subsequently, based on this analysis, feed rate and depth of cut were included as input parameters aside from the acceleration amplitude of vibrations in radial and tangential directions to develop a refined first order multiple regression model for surface roughness prediction.
