Statistics of 1000 simulations with randomly selected parameters, for burn wound propagation, with and without vitamin E treatment. The parameter ka1 is a random variable in an interval which contains the natural production rate of vitamin E, 1.4×10−4 Mh−1. For the untreated cases, we take ka2 =0, and, for the treated cases, we take ka2=5×1.4×10−4 Mh−1. (A) Time history of the burn propagation. The marks ‘x’ and ‘o’ stand for the mean of the burn propagation over 1000 simulations at each time, and the bars for the standard deviation. (B) Histograms of the statistics at T=12 for treated (blue) and untreated (red) cases.
