Russian English-writing scientists are recognized not only for their profound knowledge of any professional area, but also for abundance of definite articles used in their writings. They conscienciously believe that each noun is supplied by the article, which is, in general, true, but, grammatically speaking, zero article is also an article.

The results of the analysis have been calculated and presented in explicit and unambiguous way.
