This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). Please note that an Expression of Concern has previously been published to alert readers to an ongoing investigation into this paper. This retraction supersedes the Expression of Concern. This article has been retracted at the request of the editor. In investigating concerns brought up regarding the article, the editor reached out to the authors for an explanation. Furthermore, the editor discovered suspicious changes in authorship between the original submission and the revised version of this paper. In summary, the author names Nevzat Akkurt (new first author), Mustafa Z. Mahmoud and Anas Abdelrahman were added to the revised paper without explanation and without the exceptional approval by the editor, which is contrary to the journal policy on changes to authorship. The authors failed to provide a satisfactory explanation to the above points. The editor therefore feels that the findings of the manuscript cannot be relied upon and that the article needs to be retracted.
