Kirkuk Journal of Science (Kirkuk J. Sci) is using double-blind peer reviewing system to assure the quality of the publication. The manuscript is accepted for publication if two expertice reviewers recommended that, therefore some times a third reviewer need to be assigned. The author should first register in our online manuscript management system and then submit their manuscript. We will use iThenticate to check similarities prior to sending to reviewers. The articles will be reviewed by two reviewers or by three if one of them reject it. Their comments will be assessed by the editors which either reject in case of failed to fulfill the requirement or reviewer comment passed to the authors for revision, the author should resubmit the revised manuscript to the journal which is checked again by the editorial board, once final decision for publication made, a letter of acceptance being send to the author and process of production and publication followed.
