11. A micro annulus is the formation of microscopic cracks in the cement sheath. 12. Enlargement of the annulus requires its size reduction and stabilization by an annuloplasty. 13. The annulus , and smooth below except for fragments of the universal veil. 14. The cloaking region is to be contained within the annulus R 1 2. 15. On the annulus , the problem reduces to finding an extension for in. 16. It also has no tympanic annulus and stapes. 17. There is a fuscous annulus on the discocellular. 18. Baroclinic instability can be investigated in the laboratory using a rotating, fluid filled annulus . 19. Once at the surface, the gas is collected through piping connected to the annulus . 20. The annulus is commonly enlarged, it must be reduced and stabilized by an annuloplasty.
