I appreciate all the care with the deadlines, the suggestions and, mainly, the joy with which you work with us! Thank you Professor Francisco Louzada for the invitation to participate in the project that motivated this research, this was an unexpected but very timely change! I thank you for running the project as a whole, for fighting for our team and keeping us at the forefront of Petrobras' priorities! Furthermore, I am very grateful for the unique experience of having you, too, as a mentor. There were so many monitorings, courses, workshops and projects, and all this with so many different themes, and often simultaneously! hahahah After the despair is over, there is only thanks! hahahah I also want to thank in a very special way the others teammates who helped me in the idealization of methods, obtaining data, writing texts and publishing the results.
