Oral Presentations

(slides + 15-minute pre-recorded video)

If you need to report errors, please contact the organizers at pg2021@powdersandgrains.org 

In order to make the most of the virtual P&G, we have made some important changes to the traditional structure of the face-to-face P&G. These are the most important facts:

(1) Pre-recording: Your contributed talk will be pre-recorded and uploaded by you to the Underline platform well in advance (deadline is Jun 14). All material will be published Open Access with a DOI (be careful not to include copyrighted material, see the training material). The videos will be processed by Underline, including addition of conference logo and closed-captioning (this is why you need to upload your material before Jun 14). Underline and P&G provide training material, access to a easy-to-use recording software, and a help-desk (you may request a short video call to solve problems). You will have to upload your slides in PDF and the video of your talk (max time 15 min). To upload your material you will need to fill this upload form with information about you and your talk and a permission grant for P&G and Underline to use the material. You will have to be present at your designated talk session for the live Q&A. You can see the questions that participants pose in writing and prepare yourself in advance. Your paper ID is the one that identifies your paper in the proceeding with the format epjconfXXXXXX, where XXXXXX is a 6 digit number.

(2) Schedule: The conference will be spread over one month with only one day per week for gathering live. Have a look at the program. Save dates and times in your calendar! You will have a 6-minute time slot to answer questions live. Have your slides handy for screen-sharing.

(3) Watch and ask in advance: During the week preceding the gathering day, all participants are expected to watch the corresponding talks and pose questions in writing in the Underline platform. Participants can also vote for questions that are interesting so these are asked first by the chair of the session during the Q&A live time. Participants can also visit posters and pose questions there.

(4) Networking: There will be lounge areas for you to walk around with your avatar and meet other participants. You can open video conversations with them.
