How this score is calculated

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.

Abstract

The laws of the foam stabilization by mixtures of surfactant of different nature: sodium dodecyl sulfate C 12 H 25 OSO 3 Na and cetyltrimethylammonium bromide C 16 H 33 N(CH 3 ) 3 Br with a nonionic polymer, polyvinyl alcohol were established. High stability of foams from mixtures of surfactant-polyvinyl alcohol compared with the individual components can be related to the formation of mixed structured layers of surface active associates of polyvinyl alcohol with surfactant contributing to thickening of foam films.
