Re-Affirmations for the 38th International Symposium on Combustion are due in one week on 23:59 EST, 24 September 2020. Please remember that you must complete a Re-Affirmation to Present pertaining to the Hybrid Symposium model, even if you have already completed an earlier affirmation.

Please complete the Re-Affirmation to Present form to the best of your knowledge. We understand that given the current state of travel, circumstances may change. We recommend that delegates affirm and register for virtual attendance. If travel situations improve, delegates can later change to in-person attendance by paying the difference in registration fees.

As a reminder, the Symposium will take place in Adelaide, Australia from the 24th through the 29th of January 2021.
