Figure 9.

Test of the Mathematica (upper panel) and R (lower panel) implementations of GUTS‐RED‐SD and GUTS‐RED‐IT models with increasing multiplication factors for pulsed exposures, with exposure from day 3 to day 5. The external concentration of initially 5 ([D]) has been multiplied by factors from 1 to 50 (rainbow colours, first panels from the left). Second panels show the scaled damage; third panels show the survival rate over time for model GUTS‐RED‐SD and fourth panels for model GUTS‐RED‐IT. Parameters for model GUTS‐RED‐SD were: h_b = 0, k_D = 0.3 (time⁻¹), b_w = 0.5 (L mol⁻¹ time⁻¹) and z_w = 2.5 ([D]); parameters for model GUTS‐RED‐IT were: h_b = 0, k_D = 0.3 (time⁻¹), m_w = 2.5 ([D]) and β = 2 (−). Table 2 gives a full list of parameters with the explanation
