Announcements

From 01/02/2020, there have been changes in the journal's norms, where at least 50% of the references must be articles published in journals indexed in Scopus, Scielo or ISI Web of Knowledge, in the last ten years. References to books, theses, dissertations and bulletins will be allowed as long as their inclusion in the article is justified and as long as it does not exceed 50% of the total.
