0 a piece of metal, wood, rubber, etc. with a pointed edge at one end and a wide edge at the other, either pushed between two objects to keep them still or forced into something to break pieces off it: --
1 women's shoes with a heel all the way under the shoe --
2 to make something stay in a particular position by using a wedge: --
3 a piece of wood, metal, or other material with a pointed edge at one end and a wide edge at the other, used to keep two things apart or, when forced between two things, to break them apart: --
The small smooth-surfaced donor cell was wedged between the zona and the ooplast to facilitate close membrane contact for subsequent fusion.
The maximum quantal flux was log 14.08 quanta incident cm 2 s 1, which could be attenuated by neutral density wedges.
Over time, pieces can break off, travel toward the brain, become wedged in a smaller branch of the artery, and cause a stroke.
Calibrated neutral density filters and wedges were placed in collimated and focused por tions of the beams, respectively.
Two examples of these progradation wedges are presented in detail.
At the parasequence and sequence scales, facies patterns consist of alternating carbonates and wedges of shale derived from opposite sides of the foreland basin.
A solution was obtained in the manner described above for 22.2" and 45" semiangle wedges.
Most of the larger deviations occurred in wedged fields.
