Papers may be submitted on the understanding that the work has not been published before in other journals, is not considered for publication elsewhere and has been read and approved by all authors. All manuscripts were screened for the originality of content submitted before publication.
We advise authors to read Guidelines for Preparing Articles thoroughly before submitting their manuscripts (the requirements for the preparation of articles are specified in items 1-7).
Articles must be submitted with one review form. Two more reviewers are appointed by the Editorial Board (see Peer review policies).
