For example, even if the differences in costs have been underestimated, endothermal treatment would remain the optimal strategy even if the costs of all the other treatments are half of what we estimated in the base case.
Analyses of NYSs by DSC show wide and single endothermal peaks which indicate the lack of polymorphism and the impurity of samples.
In presence of ofloxacin, except for each diluent peak located above melting point of the drug that was obliterated, other endothermal features of both these diluents were retained approximately at their original temperatures.
The samples then suffer a melting process at 196-210C with a sharp endothermal peak in DTA curve and without weight loss in the corresponding TG curve, and then decomposing at 270-840C temperature interval.
At higher temperature an endothermal phase change takes place in the temperature interval 120-170[degrees]C.

m] were taken as the peak values of the respective exothermal and endothermal processes in the DSC thermograms.
On the contrary, with long reaction times (90-120 min), the endothermal shift due to the glass transition tends to become wider and broader, suggesting the presence of linked chains.
Onifine P decomposes by an endothermal instead of an exothermal reaction.
On the other hand, the DSC curve of the copolymer prepared with a higher amount of initiator (2/1/1/1) showed four distinct endothermal transitions, clearly indicating that the initiator concentration affects the copolymer structure and that the copolymer structure (composition and average molecular weight) can affect the thermal stability of the obtained copolymer.
c]) were determined as the peak value of the endothermal and the exothermal phenomena in the DSC curve, respectively.
