Assessment of the paper includes an assessment of originality and the importance of research, organization of the paper, methodology, presentation of the results, force of conclusion and the overall quality of paper. Reviewers are required to inform the editor about any potential conflict of interest in relation to authors or the content of their paper that they were asked to review. In most such cases they should be excused from reviewing the paper. Other responsibilities of reviewers include the handling of paper as confidential file and completing the reviews on time. The reviewer should not show paper to anyone without the express permission of the editor. Reviewers should be respectable in their comments of the paper addressed to the author. In the case of inappropriate comments, editors may reject to convey such comments to the authors or even not show all reviewer comments to the authors. Reviewers are not allowed to use research data described in a paper that they received for review for their own research. Reviewers should not communicate directly with authors or reveal themselves to authors, except with their signature under remarks as part of a review or as otherwise agreed with the editor.

The review should also point out any deficiencies in the text of the paper. The suggestions about updates or changes contributing to a higher valorisation of the article are desirable.
