Copyright

An indispensable condition of accepting papers for publication is that authors should agree to assign copyright to the publisher. The publisher is responsible for dealing with requests for printing or copying, and for protecting authors’ right.

Authors must obtain written permission to use any material (figure, table, or data), which has been published elsewhere, in their articles. They must also include in their manuscripts any credits requested to the source. PDF files of letters granting permission should be presented with submitted manuscripts.
