We prepared a scientific publication and sent it to a scientific journal, but there were problems with the English language. Then the editors of this journal offered to apply for services in LetPub. We made it. Office Coordinator Marise Facher was in active correspondence with us , answered all questions. The specialists of LetPub had a very good work on our article. They amended the text of the article and made the explanations. Very good service. Many thanks!
