By Chow, Judith C Watson, John G; Chen, L-W Antony; Chang, M C Oliver; Et al ABSTRACT Thermally derived carbon fractions including organic carbon (OC) and elemental carbon (EC) have been reported for the U.S.

Word of the Day
  • A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
The word 'pawl' probably comes from a Latin word meaning 'stake'.
