Uniquely, the Adams ring includes five distinct arcs, named Fraternité, Égalité 1 and 2, Liberté, and Courage.

It confirmed that occasional occultation events observed before were indeed caused by the arcs within the Adams ring ( see below ).

The brightest parts of the Adams ring, the ring arcs, were the first elements of Neptune's ring system to be discovered.

The Adams ring is known to comprise five short arcs, which occupy a relatively narrow range of longitudes from 247 ° to 294 °.

The arcs in the Adams ring remain unexplained.

It will also create secondary Hall currents, and accelerate magnetospheric particles — electrons in the arcs of the polar aurora, and singly ionized oxygen ions ( O +) which contribute to the ring current.

Fairy rings are detectable by sporocarps in rings or arcs, as well as by a necrotic zone ( dead grass ), or a ring of dark green grass.

Patterns other than the basic ring or arc are also possible: circles, doubled arcs, sickle-shaped arcs, and other complicated formations are also formed by this process.

This ring is very narrow, with a width not exceeding 50 km, and has five embedded bright arcs.

Various resonances between the ring particles and Galatea may also have a role in maintaining the arcs.

The ε ring seems to consist of a number of narrow and optically dense ringlets, some of which may have incomplete arcs.

Something ( probably incomplete arcs ) definitely existed around Neptune, but the features of the ring system remained a mystery.

This ring is narrow, slightly eccentric and inclined, with total width of about 35 km ( 15 – 50 km ), and its normal optical depth is around 0. 011 ± 0. 003 outside the arcs, which corresponds to the equivalent depth of about 0. 4 km.

The arcs are discrete regions within the ring in which the particles that comprise it are mysteriously clustered together.

The normal optical depths of the arcs are estimated to lie in the range 0. 03 – 0. 09 ( 0. 034 ± 0. 005 for the leading edge of Liberté arc as measured by stellar occultation ); the radial widths are approximately the same as those of the continuous ring — about 30 km.

The highest resolution Voyager 2 images revealed a pronounced clumpiness in the arcs, with a typical separation between visible clumps of 0. 1 ° to 0. 2 °, which corresponds to 100 – 200 km along the ring.

A third theory proposed in 1986 requires an additional moon orbiting inside the ring ; the arcs in this case are trapped in its stable Lagrangian points.

From its surface extruded great white fingers, resembling cirro-stratus clouds, which rose to 40 degrees above the horizon in sweeping arcs turning downward toward the poles and disappearing in seconds to be replaced by spectacular concentric cirrus like rings moving out from the blast at tremendous initial velocity, finally stopping when the outermost ring was 50 degrees overhead.

It is apparent from the above and from experimental evidence that the cooling requirements for the anode of free burning arcs are large compared with those for the cathode.

Archipelagos are often volcanic, forming along island arcs generated by subduction zones or hotspots, but may also be the result of erosion, deposition and land elevation.

Furthermore, the poles of the permanent magnet are arcs of a circle.

Because arcs of circles and ellipses cannot be exactly represented by Bézier curves, they are first approximated by Bézier curves, which are in turn approximated by arcs of circles.

Large-scale structures are very long arcs which can cover over a quarter of the solar disk but contain plasma less dense than in the coronal loops of the active regions.

The interconnections of active regions are arcs connecting zones of opposite magnetic field, in different active regions.

Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and relationship types are arcs, is not restricted to being a hierarchy or lattice.

So the area enclosed by an ellipse is easy to calculate -- it's the lengths of elliptic arcs that are hard.

Each node represents a concept and arcs are used to define relations between the concepts.

Circles, arcs, and hyperbolae of positions are often referred to as lines of position.

If a point X is located on a parabola which has focal length and if is the perpendicular distance from X to the axis of symmetry of the parabola, then the lengths of arcs of the parabola which terminate at X can be calculated from and as follows, assuming they are all expressed in the same units.

For example a spherical polygon is drawn on the surface of a sphere, and its sides are arcs of great circles.

Neptune's rings are very unusual in that they first appeared to be composed of incomplete arcs in Earth-based observations, but Voyager 2's images showed them to be complete rings with bright clumps.

Port Charles used the practice of running 13-week " story arcs ", in which the main events of the arc are played out and wrapped up over the 13 weeks, although some storylines did continue over more than one arc.

Notable story arcs of this time are " The X-Tinction Agenda " in 1990, " The Muir Island Saga " in 1991, " X-Cutioner's Song " in 1992, " Fatal Attractions " in 1993, " Phalanx Covenant " in 1994, " Legion Quest "/" Age of Apocalypse " in 1995, " Onslaught " in 1996, and " Operation: Zero Tolerance " in 1997.

Notable story arcs of this decade are " Revolution " ( 2000 ), " Eve of Destruction ," " E Is For Extinction " ( 2001 ), " Planet X ," " Here Comes Tomorrow ," " Gifted ," ( 2004 ) X-Men: Phoenix-Endsong, " House of M ," " Decimation " ( 2005 ), Deadly Genesis ( 2005 – 2006 ), " Endangered Species " ( 2007 ), " Messiah Complex " ( 2007 – 2008 ), " Divided We Stand " ( 2008 ), " Manifest Destiny " ( 2008 – 2009 ), X-Infernus, " Messiah War ," " Utopia ," " Nation X " and " Necrosha " ( 2009 ).

Hecks is yet another variant of Hex in which the tiles of the square board are irregular polygons and the graph formed by polygon edges is trivalent, i. e. each node has precisely three incident arcs.

The series ' final two arcs are in some sense are about Buffy's relationships with Angel and Spike.

Profiles are drawn either with an effective Earth radius simulated by a parabolic arc -- in which case the ray paths are drawn as straight lines -- or with a " flat Earth "-- in which case the ray paths are drawn as parabolic arcs.

An ogee ( or ) is a curve ( often used in molding ), shaped somewhat like an S, consisting of two arcs that curve in opposite senses, so that the ends are parallel.

It also has the distinction of retelling the two distinctly separate story arcs of the first four episodes of the first anime series by merging them together and somewhat massively rewriting episode 2 to 4.

The show also spawned similar Paul Henning produced rural sitcoms such as Green Acres and Petticoat Junction which were eventually linked together in cross-over episode arcs.

He was the first to use thickness of a stroke to indicate voicing ( voiced consonants such as and are written with heavier lines than unvoiced ones such as / p / and / t /), and consonants with similar place of articulation were orientated in similar directions, with straight lines for plosives and arcs for fricatives.

Also, material can be accreted horizontally when volcanic island arcs, seamounts or similar structures collide with the side of the continent as a result of plate tectonic movements.

The arcs do generate ozone and nitrogen oxides, giving the skin the well known " ozone smell " similar to the smell of a lightning storm.

The volcanoes may have been similar to island arcs.

It flies parabolic arcs similar to those of NASA's KC-135 Reduced gravity aircraft.

Further, in On similar arcs, he commented on Ptolemy's Karpos ( or Centiloquium ); many scholars believe that ibn Yusuf was in fact the true author of that work.

It is thought that they represent the remains of a volcanic island arc, approximately similar to the island arcs of the west Pacific today.

It will feature multi-episode arcs and McCallum has indicated that character development will follow an approach similar to the Game of Thrones TV series.

A footrest is incorporated into the bottom of the cradleboard, as well as a rounded cover over the infant's head that arcs out from the cradleboard, similar to a canopy or a modern-day baby carriage hood.
