This second of five Demonstrations is a plot of the nonlinear Weibullian inactivation rate,
, a measure of a microorganism's heat resistance, as a function of temperature (in degrees C). You can vary the two parameters of the log-logistic equation: the lethal temperature marker,
, and the lethality rate factor,
, which controls the slope of the curve at temperatures >>
. Notice the automatic scaling of the
axis; it is different in each example.
