This procedure was carried out by means of a complete three-level factorial experiment design, with central point in triplicate.
In order to study the factors affecting leaching, a screening step was used involving a full factorial design with central point for three variables in two levels (23).
A full factorial 23 design with central point in triplicate was applied with dough formulated with partial substitution of wheat flour by RS (12.5 g/100 g) and the enzymes: transglutaminase (0 8 mg/100 glucose-oxidasedase (0 5 mg/100 g) and xylanase (0 1 mg/100 g).
We applied a four-factor at two-level factorial design with central point to synthesize forty mock solutions spiked with two pathogen surrogates, Salmonella Typhimurium and bacteriophage PP7, selected as bacterial and viral models, respectively.
Carbon and nitrogen constituents of the culture medium were optimized using a 22 factorial design with central point followed by a multiple response optimization coupled to the desirability function approach.
In this work, the composition of bottom sludge was determined and MES were developed in order to study their application on the treatment of aged oil sludge using Factorial Design with Central Composite (FDCC).
To identify the effects of the main factors and their interactions on copper removal efficiency and to optimize the process, a full 24 factorial design with central points was performed.
A 24-factorial design with central point was used to evaluate the influence of hydrochlorothiazide (10%and50%0%, w/w), HPMC (binder, 4% and 7%, w/w), sorbitol (0% and 10%, w/w) and water (granulation liquid, low and high level) on pellet yield, size (Feret mean diameter) and sphericity (aspect ratio and two-dimensional shape factor, eR).
The trial is designed with central stratified randomisation which secures against selection bias.
Strengths of the present study include the trial design, with central randomization, concealment of group allocation, baseline comparability of groups and an acceptable proportion (>0.8) of those randomized providing primary outcome data.
The full launch comes after a beta period working with a range of top brands including Renault who showcased three of their own videos to highlight their design competition with Central St Martins as part of an overall collaboration with the Guardian to promote their electric car ZOE.
