The PPAM is a biannual journal one that is published twice a year.

Please submit your article via our editorial managing system. Electronic submission substantially reduces the editorial processing and reviewing times and shortens overall publication times. Please click “Submit Paper” on the specific journal's page. The link “Submit a New Manuscript” leads you directly to the submission system used by the journal.

The complete review process takes about 2-3 months after the acknowledgement of the submission e-mail of the contributor.
