Message: “article not found in database” (статья не найдена в базе)

Hello to everyone

I ve tried to download a couple of articles (from Journals) but I couldnt do it. Instead this message showed up. Does anybody know, why I cannot download the articles? I have to mention that these articles are not new ones.

(article examples :

Thank you in advance!
