Author Guidelines


All submissions uploaded to the manuscript evaluation system will be investigated in weekly meetings by the Editorial Board for the control of their scientific contents. Individual views of board members are received and the final decision on the submission is given by the Editor in chief. Submissions with scientific contents are assigned a section editor for further processes. Section editors send a manuscript as soon as possible to 2 reviewers with a PhD degree at the least for a review request. The reviewers are asked to inform the section editors in 5 days to inform the section editors about their decisions (accept or refuse to review) on evaluation of the manuscripts. Section editors assign new reviewers for those who refuses the review request or who does not respond in 7 days. Reviewers accepting the manuscripts for evaluation complete their review tasks in 15 days and send their review reports to section editors with which they reject the manuscript or ask for a resubmission after revision. TUJNS applys double blind review process. Section editors make a decision considering the reviewers’ reports and inform the Editor-in-Chief the decision. Than Editor-in-Chief give the final decision about the manuscript and inform the author(s) about the decision.



All submissions to Trakya University Journal of Natural Sciences should be original studies. The authors are encouraged to follow the ethic guidelines of Committee on Publication Ethics (COPE). All submissions undergo a plagiarism control by the Editor using the web based iThenticate program to confirm their originality as a natural necessity to keeping rights of the authors and to meet the journals aditorial responsibilities. The editor considers the report of the plagiarism control in terms of not only numerical values of the overlap bu also in other ethical points that authors should pay attention in citations, and then makes a decision to move the manuscript in further evaluation steps or not.

If a widely known experimental method is used, the method does not need to be explained in detail. In this situation, indicating only the name of the experimental method or citing the study who used the method for the first time will be enough.

Results: Obtained results should be given in this section without any comment. Results can be explained with tables, figures or graphics, if necessary.

Discussion: Results must be discussed, but unnecessary duplications should be avoided. In this section, rather than giving literature data, authors should focus on their results considering similarities and differences with and between previously conducted researches, and should discuss possible reasons of similarities and differences. The contribution to science and importance of the obtained results should also be mentioned as much as possible in this section.

Acknowledgements: Should be as short as possible. Thanks are usually made to institutions or individuals who support the study or to experts who reviewed the article before submitting to the journal. Acknowledgement section should be given before the references section in a separate header.
