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 chemical analysis of coal from the Kushmurun deposit in Kazakhstan and its ash was performed. Data on the X-ray diffraction and thermal analysis of the coal ash are given. The chemical activity of the coal was determined. The specific heat capacity of the coal was studied by dynamic calorimetry, and its heat of combustion was calculated.
