Submission fee has to be paid at the moment of submission. The Corresponding author has to send copy of deposit slip (must have readable remitter's name in English) along with submission date.

GMR understands that the payment process can be difficult and demands author's time to be done. There is the option to immediately make the full fee payment instead of paying separately.

• For Brazilian authors, the submission fee is US$ 250 and the publication fee is US$ 200.
• For authors from other countries, the costs are US$ 250.00 of submission fee and US$ 1100.00 of publication fee.
