 Prosthetic ring for heart surgery - Patent 5607471
The prosthetic ring of claim 1, wherein the core is assembled of at least two segments of material, one of the segments including the rigid portion of the core and another of the segments including the flexible portion of the core.
In normal mitral, tricuspid, or aortic valves, the valves overlap at the center of the fibromuscular ring that surrounds the valve, ensuring that the valve prevents backflow of blood from the ventricle to the atrium or from the aorta to the ventricle.

 Design of profile ring rolling by backward simulation using upper bound element technique (UBET) Journal of ...
Ring rolling is a metal forming operation that reduces the thickness (cross section) and enlarges the diameter (circumference) of the workpiece by a squeezing action as it passes between two rotating rolls.
For example, ring rolling is poor in filling the roll cavities, especially when they are too deep, due to the fact that during the ring rolling process the cross section of the ring is reduced, resulting in an enlargement of the diameter of the ring without adequate filling of the roll cavities.
The ring cannot generally be deformed or rolled to the final shape, with a desired ring diameter, in a single pass.

 Christopher Trinh's Polar Ring Galaxy Research Data Reductions Page
From the B image, we estimate the diameter of the polar ring is 558 pixels and we convert this number to arc seconds using 0.1'' per pixel.
The diameter of the polar ring is approximately equal to the angular size of the polar ring in radians times the distance of UGC 7576.
Thus, UGC 7575's polar ring is approximately 27 kpc in diameter.

 Domain (ring theory) - Wikipedia, the free encyclopedia
In abstract algebra, a domain is a ring with 0 ≠ 1 such that ab = 0 implies that either a = 0 or b = 0.
Zero-divisors have a geometric interpretation, at least in the case of commutative rings: a ring R is an integral domain, if and only if it is reduced and its spectrum SpecR is an irreducible topological space.
The Weyl algebra is the ring of differential operators with polynomial coefficients.

 Eye dropper bottle attachment for post-surgical and general use - Patent 4834727
The attachment of claim 2 wherein said oval ring is reduced in size and adapted to fit within the orbital area of the eye.
To attach the hook ring instrument to a dispenser bottle, the hook ring H and its horizontal post F are securely grasped, the bottle 10 inverted and its neck 14 pressed into hook ring H. With bottle firmly attached, instrument is ready for use as described in connection with FIG.
The split ring S is aligned within the center area of rim R to bring the dispenser bottle 10 and nozzle 20 into the center of the rim and high enough over the eye area to avoid contact.

 Homomorphisms   (Site not responding. Last check: 2007-09-08)
A ring monomorphism is 1-1, with a kernel of 0.
A ring isomorphism is 1-1 and onto, essentially a relabeling of the ring elements.
A ring homomorphism respects + and *, hence the image of the product of two ideals, or finitely many ideals, is the product of their images.

 Heart valve ring reverses damage from congestive heart failure, easing symptoms
A prospective study of the first 25 patients who had surgery to install the ring shows that it reduced the leakage of blood back through the mitral valve, which leads to the heart's main pumping chamber.
The ring was co-invented by Steven Bolling, M.D., the University of Michigan Cardiovascular Center cardiac surgeon who presented the results on behalf of the research team, and by Italian cardiac surgeon Ottavio Alfieri of the St. Raffaele Hospital in Milan.
The Geoform ring, and the Acorn device, Bolling says, should also give heart failure patients a viable option when heart donor shortages limit the opportunity for a heart transplant, which is currently the standard treatment for patients with severe congestive heart failure associated with end-stage heart disease.

 HJM, Vol. 29, No. 3, 2003
If R is a unital ring, then the left multiplications by elements of R obviously form endomorphisms of the additive group of R. In fact they form a group direct summand of the endomorphism ring and if the complement is trivial, then these rings are called E-rings which are well-studied.
Finally, we show that in ZFC there exists an almost-free ring R of minimal uncountable cardinality such that the endomorphism ring of R is isomorphic to the direct sum of the integers and R itself.
A is a going-down ring (resp., universally going-down ring) if and only if the weak Baer envelope of the associated reduced ring of A is a going-down ring (resp., a universally going-down ring).

Every detector group is processed separately one ring at a time, and finally all the results are combined.
The rings are filtered with a Mexican Hat Wavelet filter with parameters tuned to emphasize the point sources in the signal.
As a point source is usually visible in several rings, the detection results from all rings must be consolidated to prevent duplicates and to determine the correct values for coordinates and brightness.

 reg.paper_1
A further test of whether ring current is actually reduced comes from the relationship between the chemical shift of the internal methyl protons and H-2 of 13.
Clearly, the relationship between the methyl groups and the ring periphery in 13 is not very different from that in 1, in particular, the distance from the methyl group (atom 1 in Y) to the mid point of the 3-4 bond in Y is 1.98 A in 13 and 1.
Thus, in both compounds, the methyl group is situated at approximately the same position relative to the center of the magnetic ring current field, and therefore any difference in chemical shift should be due primarily to a difference in ring current, and not a shift in position of the methyl group.

 The Open Die Forging Process
A ring formed by the casting process is often plagued with substandard strength and integrity, while a ring cut from plate is susceptible to fatigue and carries with it the price of the excess material.
Three different metalworking processes were attempted to make one ring: a forging, a casting, and a rolled and welded plate.
Extensive welding on the fabricated ring reduced part integrity, jeopardized corrosion resistance, and caused distortion of the ring's shape.
