E mail.riobrancofac.edu.br

It looks like you've provided an email address from the University of Rio Branco (UFRJ) in Brazil!

The email address e mail.riobrancofac.edu.br appears to be a valid email address from the university. The domain riobrancofac.edu.br is associated with the Federal University of Rio Grande do Norte (UFRN), not the University of Rio Branco (UFRJ).

If you're trying to contact someone at UFRJ, you may want to try using a different email address or searching for the person's email address through the university's directory or website.

Would you like me to help you with anything else?
