The authors are usually requested to resubmit the revised paper within 15 days, and it is then returned to the reviewers for further evaluation. The publishers normally allow one round of revision, and in exceptional cases, a second round of revision may be allowed. If further revision is needed, then the manuscript is rejected, and the author is requested to resubmit the manuscript for fresh processing.
The final decision regarding acceptance or rejection is by the editor-in-chief, depending on his/her assessment on the revisions recommended by the referees, and about the overall quality of the revised manuscript. In rare cases, manuscripts recommended for publication by the referees may be rejected in the final assessment by the editor-in-chief.
