F of noncommutative numerical motives; see x5. In contrast to Kontsevich's approach, the authors used Hochschild homology to formalize the 'intersection number' in the noncommutative world. The main result of this article is the following theorem. Theorem 1.1. The categories NC num(k) F and NNum(k) F are equivalent (as rigid symmetric

Heavy Duty Back-Up Rings Heavy Duty back-up rings are configured with a greater axial thickness (T) dimension. The extra thickness provides more extrusion protec-tion for O-Rings. These rings are interchange-able with MS27595, MS28774, MS28782 and MS28783 back-up rings used in MIL-G-5514 packing glands. Heavy duty rings are available

Seal Rings The sets are comprised of double-turn rings in either 2 rings per set or 3 rings per set. The double-turn rings fit tighter in the bore or on the shaft, provide complete 360 surface contact and resist higher axial/radial forces than single-turn ring sets, for medium to heavy duty applications.

seminear-rings using loops and groupoids which we call as groupoid near-rings, near loop rings, groupoid seminear-rings and loop seminear-ring. For all these concepts a Smarandache analogue is defined and several Smarandache properties are introduced and studied. The ninth chapter deals with fuzzy concepts in near-rings and gives 5

Saturn’s most prominent rings are the A, B, and C The age and fate of Saturn’s rings Jonathan Henry When Saturn was the only known ringed planet, the rings were believed to be as old as the solar system—4.6 billion years in the conventional chronology. The existence of the rings to the present day was taken as evidence of this chronology.

A hybrid design is possible: rings can be constructed in a hier-archy such that groups of nodes share a simple ring interconnect, and these “local” rings are joined by one or more “global” rings. Figure 1 shows an example of such a hierarchical ring design. Past works [43, 51, 21, 44, 19] proposed hierarchical rings as a scalable network.

Our rings are used for transmission, bearing, valve, gauge, appliance, and general industrial applications. We have produced this Technical Manual for guidance in the design of rectangular, uniform section, coiled retaining rings. It is intended for engineers and technicians who desire a comprehensive review of retaining rings and their .

tary dust is unusual in the size distribution of its various rings: the broad and diffuse E ring seems to be mainly 1-micron grains whereas the narrow F and G rings have quite steep size distributions, indicating the predominance of very small grains. Sur-prisingly little dust resides in the main Saturnian rings, except in the localized spokes.

the main rings—Saturn’s faintest rings and satellites became visible. Which Galilean moon is volcanically active? . The main rings (A and B) are densely packed. In contrast, the outer rings are composed of widely dispersed particles. 656 Chapter 23 Saturn: The Elegant Planet Build Reading Literacy Refer to p. 124D in Chapter 5, which .

Backup rings Back up rings minimize non-metallic sealing rings from extruding into the space between the piston rod and packing cup. The back up does not seal on the rod; it does seal on the packing case cup face. It is bored to have a small clearance on the piston rod and has no segmental gaps when positioned. Back up rings are typically

himself. Sauron did have a hand in forging the Rings of the dwarves and humans, however, and as a result, they had the power to corrupt that the elven rings did not. The One Ring is a Ring of Power. Indeed, it is the ruling Ring of Power. The Hobbit is the prequel to J.R.R. Tolkien s famous trilogy The Lord of the Rings.

Composition of Saturn’s Rings Rings are composed of ice particles moving at large velocities around Saturn, but small relative velocities (all moving in the same direction). Shepherd Moons Some moons on orbits close to the rings focus the ring material, keeping the rings confined. Divisions and Resonances Moons do not only serve as .

READING BETWEEN THE RINGS One way scientists are learning about past climate is by studying tree-rings. This field of research is known as dendrochronology. Scientists can use tree rings and cores to measure the age of a tree and learn more about the local climatic conditions the tree experienced during its lifetime. In temperate areas, like most

round your finger. The two pairs are called the V-rings and the Z-rings. The red lines indicate the essential difference between the pairs. This pair are the V-rings, the one on the right is the Smooth-V (SV ) and the other one is the Dented-V (DV ). Don't be confused by the fact that both rings are dented; SV has a single dent on each

certain conditions, O-rings can also be used for recipro - cating, rotating and superimposed screw movements (dynamic application). If the installation space is designed properly, they are constructed properly and the correct material is chosen, pressures up to 1,000 bar can be sealed. If necessary, back-up-rings must be used. O-rings are used

phism rings of supersingular elliptic curves appear of quite a different flavor. The geometry provides intuition for making the plunge into the world of noncommuta-tive rings and makes the arithmetic theory palatable if not refreshing.

1923 ring; on earlier rings, the school name is on banners on the shank sides. The Class of 1922 introduced women's miniature rings, which cadets often used as engagement rings, mimicking a West Point tradition. During the decade, the rings were manufactured by Auld's, Charles H. Elliott, and Bailey,

Technical Handbook O-rings The sealing principle of the Quad-Ring /X-Ring is nearly the same as the O-ring sealing. The initial sealing is achieved by the diametrical squeeze in a right angled groove. The system pres-sure itself creates a positive sealing force. Following are some advantages of Quad-Rings /X-Rings:

Saturn’s rings are composed of numerous icy fragments, while Jupiter’s rings are made of small rocky particles Jupiter’s faint rings are composed of a relatively small amount of small, dark, rocky particles that reflect very little light Jupiter’s Main Ring Data from the Galileo spacecraft show that rings were created by

It is not known for sure. It is believed that the rings have been around for a very long time, possibly since the formation of Saturn. - The Rings are composed of a large number of “ringlets”. - The inner ring has a period of 5h45m, the outer ring 14h20m Saturn’s Rings as seen from “behind” with the Sun in front eclipsed by Saturn:

The Voyager pictures show four additional faint rings. Saturn’s rings, unlike the rings of the other planets, are very bright (albedo 0.2 - 0.6). Though they look continuous from the Earth, the rings are actually composed of innumerable small particles each in an independent orbit. They range in size from a centimetre or so to several meters.

Start with the rings at about waist height. Perform push-ups on the rings. As strength increases, lower the rings until they are just above the floor; then, to make them more challenging, you can elevate your feet a little. To further increase difficulty, lean forward a little bit while you do the push-ups so that at the

counting the rings. If the year of cutting is known, the year during which each ring was formed can be determined by counting back wards from the outside ring. Such "dating" of rings may reveal that rings formed during certain extreme drought years are unusually narrow. This has 1 d to speculation that tree
