We strongly recommend our authors to carefully write the manuscript without any plagiarism, because we will check them using software (Turnitin) before we send them to the reviewers. The authors must ensure that the articles sent to the editor are the results of their work, not duplicated or recycled. If the author cites the writings of other researchers or the results of his/her own research please do not forget to write the source of the article(s).  An article that contains more than 20 percent similarity, or containing similarities without giving enough credits; containing important points in the results section and or conclusion section similar to other research; will be questioned, and the manuscript will be returned to the author/s.
