Activity coefficients of non

In chemical thermodynamicsactivity symbol a is a measure of the "effective concentration" of a species in a mixture, in the sense that the species' chemical potential depends on the activity of a real solution in the same way that it would depend on concentration for an ideal solution. The term "activity" in this sense was coined by the American chemist Gilbert N. Lewis in By convention, activity is treated as a dimensionless quantityalthough its value depends on customary choices of standard state for the species.

Datatables scrollingpagination

Scroller is a virtual rendering plug-in for DataTables which allows large datasets to be quickly drawn. Virtual rendering means that only the visible portion of the table and a bit to either side to make the scrolling smooth is drawn, while the scrolling container gives the visual impression that the whole table is visible. This is done by making use of the pagination abilities of DataTables and moving the table around in the scrolling container DataTables adds to the page.
