DOI temporarily not working properly
DOI is automatically attributed when a paper is published. However, we are making updates on the current version of the OJS system and migrating from one webpage to another one, due to a unification process of all journals from UFJF in the same portal and also to some improvements on their basis and procedures. This process can generate some inconsistencies on the webpage and its stability. Thus, our technical team says that since DOI must work on a stable page, we need to finish the migration before. Thus, please, be patient with the migration, which can take a month. As soon as I have some news I will share them with all authors.
