Each manuscript received will be submitted to blind refereeing by the Editorial Committee and, in addition, by one or two external reviewers. After this review, the responsible author will be notified about the acceptance (with or without corrections and changes) or rejection of the manuscript. In the corrected version, submitted by the authors for a second review, the corrections or changes introduced should be shown in a different color or highlighted, in order to facilitate the reviewers’ control. The Editorial Committee also reserves the right to introduce, with the knowledge of the authors, all editorial changes required by grammatical rules, the style of the journal and page layout needs.
