In the JournalArticle type, you changed the volume (v.) to ano.

[cesarep]

Yes, as specified by the norm:

As there's really no point using this format outside Brazil, in Portuguese, "Periodical" usually refers to scientific journals, so the ArticleInAPeriodical type uses the volume (v.)
Both endup having the same style apart from the "v." x "ano.", so they could both be used really

[malvarenga123]

Oh I see. So journal in this case is referring to a newspaper.
I'll use ArticleInAPeriodical, thanks.
