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.
The various compositions of sand-resin mixtures and solutions to improve their physico-mechanical properties are considered. The relationship between technological parameters, composition and properties of the binding components of sand-resin mixtures is shown. An experimental setup for the manufacture of shell molds from sand-resin mixtures is described. The optimal composition of sand-resin mixtures for heating radiator rods is proposed.
