Nice question. I think that makes part from the part of preparing the papers for publishing. So, first of all, it`s about the fact that the articles for publish must be written taking into account the rules of publishing well-defined previously.
The theme chosen must treat the subject as well, with a clearer and more accurate methodology.
You have to choose some interesting topics. Not every description that you do can not become , overnight, subject for the articles to be published.
