```thank you for your help so far... but i get always the same mistakes
after entering the solution of DH ...  (<<1>> of piecewise is not a
list of pairs) what is wrong?

In[35]:= ex2piec[Integrate[model27SA, t]]

During evaluation of In[35]:= Piecewise::pairs: The first argument \
\[Piecewise]<<1>> of Piecewise is not a list of pairs.

Out[35]= Piecewise[Most[\[Piecewise] {
{0., t <= 40.},
{560.- 28. t + 0.35 t^2, 40. < t <= 50.},
{935.- 43. t + 0.5 t^2, 50. < t <= 55.},
{-123.75 - 4.5 t + 0.15 t^2, 55. < t <= 140.},
{-6983.75 + 93.5 t - 0.2 t^2, 140. < t <= 145.},
{-10137.5 + 137. t - 0.35 t^2, 145. < t <= 150.},
