The phrase "a pawl" is correct and usable in written English.
It can be used in contexts related to mechanics or machinery, specifically referring to a device that allows movement in one direction while preventing movement in the opposite direction.
Example: "The clock mechanism relies on a pawl to ensure that the gears only move forward."
Alternatives: "a catch" or "a ratchet."
For those of you who are still spinning your gears over it, this is what a PAWL looks like.
On cars with automatic transmissions, an additional lock is usually provided in the form of a pawl that can be engaged, by placing the shift lever in the "park" position, to prevent the drive shaft and rear wheels from turning.
The distal portion of the plate has a space which connects the ratchet; (3) a connecting arm that links the ratchet to the segmental plate of ilium, which formed an articulated joint; (4) a set bolt; (5) a pawl that can cooperate with the ratchet and the set bolt, forming unidirectional articulated joint from medial to lateral.
Buy a doorknob with a pawl the same length as the one you are replacing.
The design utilized a helicene pawl whose inherent helical chirality was intended to bias the rotation of the triptycene cog.
Extension of these findings to investigate the curious presence of a deletion of two amino acids in the bridge helix of plant RNA polymerase IV (corresponding to the looped-out region proposed to act as a translocation pawl and shown as Cα-Cβ sticks in Figure 1b) led the author to a remarkable discovery that calls into question the translocation-pawl model.
Loops observed in the central portion of the helix may be a simple consequence of its inherent instability as a helix, which optimally poises it to modulate trigger-helix formation, rather than making loop-specific contacts (for example, as a ratchet pawl).
The most recent results from this systematic dissection of the bridge helix, published in BMC Biology by Weinzierl [ 7], suggest that kinking of the helix at or adjacent to segments that contact the interconnected network of RNA polymerase modules may play a more important role in the nucleotide-addition cycle than contacting the template base or looping to generate a translocation pawl.
WHEN William B. Ziff Jr., the publishing magnate who built Ziff Davis into an empire of computer magazines, decided to build himself a Xanadu on a 1,000-acre 1,000-acre Pawling, N.Y., a few miles northilltopre in Dutchess County, he sPawlingo expeN.Y.
Formation of the bridge helix loop is proposed to act as the pawl in a ratchet-like translocation mechanism to move DNA through RNA polymerase [ 2].
Degradation of eEF1A or eEF1Bα though random genetic drift in the presence of EFL is likely to be an almost irreversible step that acts as the pawl of the ratchet: a return to the ancestral state would require that the lost gene is quickly re-transferred before its binding partner diverges beyond preventing functional interaction: an unlikely scenario.
