(15) The erythroleukemia with the preponderance of proerythroblasts had a worse prognosis because many of the individuals did not survive long enough to respond to the therapy initiated.
(16) Five amino acids are preponderant (serin, prolin, glycin, alanin and taurin).

Trunnion
Definition:
(n.) A cylindrical projection on each side of a piece, whether gun, mortar, or howitzer, serving to support it on the cheeks of the carriage. See Illust. of Cannon.
(n.) A gudgeon on each side of an oscillating steam cylinder, to support it. It is usually tubular, to convey steam.
