My university has a subscription at IOPSciences
I am interesting in this article: Galochkin A.I. (1984): On estimates, unimprovable with respect to height, of some linear forms. Mat. Sb. 124 (166), 416-430. English transl.: Math. USSR, Sb. 52, 407-419.


So I went to IOPsciences site to download it (the english version !!) But it looks like IOPSciences did a mistake about this journal. This article does not exist in their data base. Can anyone manage to download this article.


I wrote to IOPSciences but I received no answer.



IOPsciences and a missing reference
I'm pretty sure a machine translation of the [paper](http://www.mathnet.ru/php/archive.phtml?wshow=paper&jrnid=sm&paperid=2059&option_lang=eng) from russian into english will be sufficient. For starters, I fed two paragraphs on pages 417-418 to <https://deepl.com>, with the following output (unedited, the only changes I made were to LaTeX the symbols):
