The manuscript received will be submitted to two referees, and returned to the author(s) for final writing. After modifications according to the referees' comments, the revised paper should be sent to the Section Editor attached to an e-mail. The Section Editor proposes the publication of the paper to the Editor-in-Chief. Exceptionally, authors can receive comments or suggestions from the Editor-in-Chief. Proof prints are sent to the authors by e-mail in a PDF file. Authors should examine them carefully and send by e-mail the misprints observed. Modifications of the paper's content are not allowed in print-proofs. The paper is then sent to two reviewers based on their qualifications, specialty and expertise. A double-blind review is used where both reviewers and the author remain and reviewers are anonymous. This prevents bias.
