All abstracts must be submitted through the online system of 50º CBG, following the sequential rules described below:

• On the official event website, you can download a template of a published abstract. The publishing of the abstracts should follow the rules described in this template.
• Abstract file page settings match: A4 sheet; margins (top, bottom, right and left) of 1.5 cm; and single spacing.

Abstracts that do not have between 350 and 500 words will be automatically disapproved, without going through the evaluation of the Session Coordinators and Scientific Committee. Title, authors and affiliation will not be counted in the sum of the words.

• During submission, a single word file formatted in accordance with the Summary Preparation Guide must be attached. After the submission, no type of correction or replacement of the file will be allowed.

The evaluation of the abstracts will be performed by the Session Coordinators and Scientific Committee, taking into consideration: (i) the relation of the abstract to the theme of the Symposium or Technical-Scientific Session; (ii) presentation of some technical-scientific contribution; (iii) which do not contain conceptual errors; and (iv) that do not represent a proposal or intentions to perform a particular study without presentation of results.

Approved abstracts may be submitted to possible corrections. Any mistake, whether typing, spelling, etc., will be the sole responsibility of the author (s).

Authors may submit as many abstracts as they wish, but for the purpose of presentation at the congress and publication in the Book of Abstracts, it will be allowed to link and validate only 3 (two) abstracts per registration.

Presentation format chosen by the author (poster or oral) will not be the final format of the presentation. The presentation format will be defined later by the Session Coordinators and Scientific Committee.
