Ladies and gentlemen,
From 1/2021, the journal will be published only in English. For this reason, please submit future submissions in English. Both British and American spellings are accepted, as long as one spelling is used consistently throughout the text. Authors whose native language is not English are strongly advised to assure the grammatical correctness of their paper prior to submission. Papers with serious deficiencies in English may be returned without review.
