Each publication is evaluated by at least two independent Reviewers from outside of the unit. In the case of paper written in a foreign language, at least one of Reviewers is affiliated to a foreign institution other than the Author's work.
As a rule double-blind review process is used (the Author(s) and Reviewers do not know their identities). In any case Editor must be sure that no conflict of interest (direct personal relationships, professional relationships, or direct scientific cooperation in the past two years) occurs between the Reviewer and the Author.
Reviewer has to fill in the Reviewers report. On its end must be an explicit request to the approval of the article for publication or its rejection.
