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

Experimental study of the features of separation process in ternary gas mixtures 0.6179 H 2 + 0.3821 N 2 – CH 4 and 0.7760 CH 4 + 0.2240 R12 – n-C 4 H 10 is conducted. Conditions of the priority transfer of the density heaviest component of the mixture are discussed. The problem is solved by the splitting scheme by physical parameters. Numerical data on the time evolution of components concentrations at different concentrations of components of the initial mixture are obtained. Calculations have shown that for ternary systems the concentration increase of the heaviest component results to the intensity growth of convective mixing.
