It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
Polyalkylene oxidephosphates were obtained by phosphorylation of polyethylene oxide and polypropyleneoxide of different molecular weight. Evaluation of flotation activity in experiments on the extraction of tungsten oxide from wolf ramite pulp showed that the introduction of oxygen donor atoms into phosphate group substituent, responsible for hydrophobization of the surface of mineral particles, increase the degree of the heavy metal extraction.
