Dear Authors

Along with your revised manuscript, you will need to:

1- Supply a cover letter in which you list all the changes you have made to the manuscript, and in which you detail your responses to all the comments passed by the reviewer(s) and the Editor.

2- When you disagree with any comment(s), please explain why in cover letter.

3- Please, colour your changes in the revised manuscript (Use a separate color for each referee) or use "track changes" that reviewers and editors can immediately recognize where the changes have been made.
