The biochemical approach also provides a mechanistic basis which can explain the yield estimates as the sum of yields and costs in component reactions rather than being simply an empirical measure derived from experiment.
The overall yield of ATP is simply the sum of the yield of each reaction.
The response value was a composite value (that is, the sum) of starch yield and sorghum peeling rate.
As challenge variables, we used either the sum of milk yield or the accumulated fat-to-protein ratio of the first 3 test-days (<120 d in milk), pre-adjusted for herd-test-day variance.
Other reported measures are the difference between one set day for peak yield (or the estimated breeding value (EBV) at this day) early in lactation and a test day late in lactation (or EBV at this day), or the sum of the yield or EBV over this time period.
Total biocrude yield reported in this study was the sum of the yields of biocrude 1 (B1) and biocrude 2 (B2) that were obtained from the DCM-assisted and acetone-assisted separations, respectively.
However, in combination with xylanases, higher yields of xylose and glucose were measured, which were greater than the sum of the yields of Accellerase and xylanase alone, clearly revealing synergistic interactions between the enzyme participants.
The percent yield of a component may be calculated by the formula (1) % yield = 100%% ∗ ∑ i = 1 n AWF i + ∑ i = 1 n RF i total, where the "total" is the amount of the component in the leaf prior to recovery, assumed to be the sum of the yields from all the AWF and all the RF from every round of recovery as well as the yield in WHE (the homogenized tissue from which the AWF had been recovered).
Weighted with the duration of each phase, the sum of velocities yields the average step size.
