That part of the veil which breaks away from the cap, called the secondary veil, forms the annulus or ring.

Severe axial loading of the spine may produce end-plate disruption rather than damage to the annulus fibrosus.
The success of this procedure is based on decompression of the disc space by producing a hole in the annulus with the cutting probe and evacuating the nuclear material with the cutting and suction probe.
Medtronic introduced Profile 3D Annuloplasty Ring with a design based on the geometry of the saddle-shaped human mitral annulus to promote natural function with the aim of repairing rather than replacing a failing mitral valve.

On the other hand, the annulus fibrosus occupies 40-60% of the disc volume.
This works for wells without packers where the annulus can be used as a pressure charge chamber.

The spectrum of a circular free Poission element of parameter c has been found by Haagerup and Larsen to be the annulus centered at zero with radii √c − 1 and √c, if c > 1, whereas the spectrum of the circular operator is the disk of radius 1.

In the Cardy case, this leads to the result Aab (t) = Xν∈I which tells us that the so-called annulus multiplicities are equal to the fusion rules.
Conformal field theory, boundary conditions and applications to string theory
The annulus is a one-loop diagram, too, and we will interpret it as the partition function for open string states.

Finally, we mention that from the result (41) one can compute the annulus coeﬃcients and show them to be non-negative integers.

We ﬁrst show that zeros of the SU (1, 1) random polynomial of degree N are concentrated in a narrow annulus of the order of N −1 around the unit circle on the complex plane, and we ﬁnd an explicit formula for the scaled density of the zeros distribution along the radius in the limit N → ∞.

The density was simply obtained by dividing the number of counted zeros by the area of the corresponding annulus.
