Clusters are not a syntactic language construct, but rather a standard organizational convention.

Clusters of galaxies are often dominated by a single giant elliptical galaxy, known as the brightest cluster galaxy, which, over time, tidally destroys its satellite galaxies and adds their mass to its own.

Clusters are larger than groups, although there is no sharp dividing line between the two.

Clusters are quite prominent in X-ray surveys and along with AGN are the brightest X-ray emitting extragalactic objects.

Clusters of galaxies are the most recent and most massive objects to have arisen in the hierarchical structure formation of the universe and the study of clusters tells one about the way galaxies form and evolve.

Clusters have two important properties: their masses are large enough to retain any energetic gas ejected from member galaxies and the thermal energy of the gas within the cluster is observable within the X-Ray bandpass.

Clusters such as the Pleiades, Hyades and a few others within about 500 light years are close enough for this method to be viable, and results from the Hipparcos position-measuring satellite yielded accurate distances for several clusters.

Clusters are also a crucial step in determining the distance scale of the universe.

He waited until 1802 ( in Catalogue of 500 new Nebulae, nebulous Stars, planetary Nebulae, and Clusters of Stars ; with Remarks on the Construction of the Heavens ) to announce the hypothesis that the two stars might be " binary sidereal systems " orbiting under mutual gravitational attraction, a hypothesis he confirmed in 1803 in his Account of the Changes that have happened, during the last Twenty-five Years, in the relative Situation of Double-stars ; with an Investigation of the Cause to which they are owing.

Clusters of galaxies should not be confused with star clusters such as galactic clusters and open clusters, which are structures within galaxies, as well as globular clusters, which typically orbit galaxies.

Clusters of ' Black Corinth ' are small, averaging, ranging from 0. 2 to 0. 6 pounds.

A recent preliminary finding is that it can explain structure formation without CDM, but requiring a ~ 2eV massive neutrino ( They are also required to fit some Clusters of galaxies, including Bullet Cluster ) and.

Clusters of homes around old Lower Kula Road are becoming denser.

Clusters in Georgian of four, five or six consonants are not unusual — for instance, ( flat ), ( trainer ) and ( peeling )— and if grammatical affixes are used, it allows an eight-consonant cluster: ( he's plucking us ).

Clusters are made of two or more consonant sounds, while a digraph is a group of two consonant letters standing for a single sound.

Clusters of chard seeds are usually sown between April and August, depending on the desired harvesting period.

The University of Kiel helped develop this radiation detector for a Mars probe. Interdisciplinary research and a university-wide infrastructure are complemented by an array of research programs that are not included in the Excellence Clusters and collaborative research centers.

His major contribution was the monumental New General Catalogue of Nebulae and Clusters of Stars ( based on William Herschels Catalogue of Nebulae ), the catalogue numbers of which are still in use, as well as two supplementary Index Catalogues.

Clusters of-ps ,-ts ,-ks, were then formed at the end of syllables.

If the Oracle database administrator has implemented Oracle RAC ( Real Application Clusters ), then multiple instances, usually on different servers, attach to a central storage array.

Applewhite and Nettles then split their followers into small groups, which they referred to as " Star Clusters ".

John Herschel observed the object again in 1833 when he cataloged it as " h 35 ", and then in 1864 when he cataloged it as " GC 90 " within his General Catalogue of Nebulae and Clusters.

Clusters of private tombs were thus formed in Saqqara around the pyramid complexes of Unas and Teti.

Through random linking between star Clusters, this construction allows universes of 5, 000 star systems or more to be generated.

Clusters of gigantic cylindrical tanks amid a maze of pipelines now dot the island ; investment has totalled S $ 31 billion in 2010.

Clusters which have enough mass to be gravitationally bound once the surrounding nebula has evaporated can remain distinct for many tens of millions of years, but over time internal and external processes tend also to disperse them.

He served four years in the Air Force as an enlisted gunner on a B-24 Liberator, flying fifty missions over Western Europe from Italy with the 736th Bomb Squadron, 454th Bomb Group, for which he received the Air Medal with three Oak Leaf Clusters.

Under the Excellence Initiative, a total of 37 Clusters of Excellence receive funding over a period of five years, with each Cluster of Excellence receiving an average of 6. 5 million euros per year .</ br >

Becker is now the Chief Technology Officer ( CTO ) of Scyld Computer Corporation, a wholly owned subsidiary of Penguin Computing, a major developer and supplier of Beowulf Clusters.

When SCO stopped selling NonStop Clusters, the former Locus team, now working for Compaq ( which had acquired Tandem in the interim ), ported the NonStop Clusters code to Linux and released it as open source.

Clusters consist of geographical areas.

The Jewel Box Clusters is a Shapley class g and Trumpler class I 3 r cluster ; it is a very rich, centrally-concentrated cluster detached from the surrounding star field.

Clusters correspond generally to the concept of an " object " in an OO language, and have roughly the same syntax.

* Gravitational lensing: Clusters of galaxies contain enough matter to distort the observed orientations of galaxies behind them.

Clusters of memes, or memeplexes ( also known as meme complexes or as memecomplexes ), such as cultural or political doctrines and systems, may also play a part in the acceptance of new memes.

Their Catalogue of One Thousand New Nebulae and Clusters of Stars was published in 1786.

The third announced the discovery of the fullerenes in " Reactivity of Large Carbon Clusters: Spheroidal Carbon Shells and Their Possible Relevance to the Formation and Morphology of Soot " in the Journal of Physical Chemistry v. 90 p 525 ( 1986 ).

Herschel's discoveries were supplemented by those of Caroline Herschel ( 11 objects ) and his son John Herschel ( 1754 objects ) and published by him as General Catalogue of Nebulae and Clusters in 1864.

He published a catalogue of his astronomical observations in 1864, as the General Catalogue of Nebulae and Clusters, a compilation of his own work and that of his father's, expanding on the senior Hershel's Catalogue of Nebulae.

Clusters amplify the signal of aposematic coloration, and individuals may participate in group regurgitation or displays.

The New General Catalogue of Nebulae and Clusters of Stars ( abbreviated as NGC ) is a well-known catalogue of deep sky objects in astronomy compiled by John Louis Emil Dreyer in 1888, as a new version of John Herschel's Catalogue of Nebulae and Clusters of Stars.

Dreyer had already published a supplement to Herschel's General Catalogue of Nebulae and Clusters ( GC ), containing about 1, 000 new objects.
