O-RING REMOVAL When removing O-rings, care must be taken to not damage the regulator surfaces in contact with the O-rings. Tools used to remove O-rings must not have any sharp edges or points that could scratch metal sealing surfaces. Sea Quest strongly recommends that all O-ring removal tools should be made of either brass or plastic. LUBRICATION
foundation on the ship. Another advantage of vertical compressors exists in their rider rings. In the case of a reciprocating compressor with piston rings, rider rings are provided to prevent each piston from contacting the corresponding cylinder liner during the reciprocating motion of the piston. Unlike the case of horizontal machines, rider
Rings and Fields 1. Rings, Subrings and Homomorphisms The axioms of a ring are based on the structure in Z. Definition 1.1 A ring is a triple (R, , ·) where R is a set, and and · are binary operations on R (called addition and multiplication respectively) so that: (1) (R, ) is an abelian group (with identity denoted by 0 and the inverse of .
Vortex rings have attracted considerable interest for a long time. Not only do they exhibit spectacular flow elds but they are of major importance in both fundamental and practical flow problems. Naturally, a great volume of research has been published on vortex rings; for recent reviews see Shari & Leonard (1992) and Lim & Nickels (1995).
The Borromean rings in Figure 1 consist of three unknots in which the red ring lies on top of the blue ring, the blue on top of the green, and the green on top of the red. Since each ring is above one ring and below another, balance is evident here as with RPS(3). Versions of the Borromean rings have appeared in diverse cultures, from
cessfully applied to the study of rings of differential operators on algebraic vari eties and filtered algebras, more generally. J.-E. Bjork provides a careful devel opment of certain aspects of filtered Noetherian rings culminating in an easy-to-understand proof of Gabber's theorem on the integrability of the characteristic variety.
A homomorphism between two rings is a function between their underlying sets that preserves the two operations of addition and multiplication and also the element 1. Many authors use the term morphism instead of homomorphism. More precisely, let (R, , ・) and (S, , ・) be two rings. The function
1Introduction to number rings A number eld is a nite eld extension of the eld of rational numbers Q, and a number ring is a subring of a number eld. This introduction shows how number rings arise naturally when solving equations in ordinary integers. Many basic questions about integers can be phrased as a problem of nding rational or
such as the size, edge structure, chemical composition, or geometry [9]. Other routes based on the alteration of the local aromaticity by the introduction of non-hexagonal rings are starting to be explored [10 14], mainly focusing on lower-order rings, while larger ones, such as seven- or eight-membered rings are typically limited to their com-

Similarities between The Lord of the Rings by J.R.R. Tolkien . The Lord of the Rings by J.R.R. Tolkien and Dune by Frank Herbert are often regarded as the pinnacles of their respective genres of fantasy and science fiction. They are sometimes compared to each other in terms of size, scope and breadth of world-building. Arthur C. Clarke,
