The UniProt Reference Clusters ( UniRef ) consist of three databases of clustered sets of protein sequences from UniProtKB and selected UniParc records.

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.

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 then formed relatively recently between 10 billion years ago and now.

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.

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

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 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.

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.

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.

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 ).

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

* Probing the Birth of Super Star Clusters: Implications for Massive Star Formation, Kelsey E. Johnson, 2005

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.

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.

The Greeks did not regard the polis as a territorial grouping so much as a religious and political association: while the polis would control territory and colonies beyond the city itself, the polis would not simply consist of a geographical area.

With the population and geographical size of the United States, he warns that citizens “ will have very little acquaintance with those who may be chosen to represent them ; a great part of them will, probably, not know the characters of their own members, much less that of a majority of those who will compose the federal assembly ; they will consist of men, whose names they have never heard, and whose talents and regard for the public good, they are total strangers to .” He also sees danger in giving Congress the power to modify the election of its own members.

Dutch geographical numbers consist of 9 digits.

The EET ( UTC + 2 ) time zone, were it drawn by purely geographical terms, would consist of exactly the area between meridians 22 ° 30 ' E and 37 ° 30 ' E. As a result, there are European locales that despite lying in an area with a " physical " UTC + 2 time, actually use another time zone ; contrariwise, there are European areas that have gone for UTC + 2, even though their " physical " time zone is different from that.

The division of a religious institute into provinces is generally along geographical lines, and may consist of one or more countries, or of only a part of a country.

This work will cover the most serious one-fourth of all land needing such treatment, and will consist of burning 250,000 acres of highly hazardous debris concentration, felling snags on 350,000 acres of high lightning-occurrence areas, prescribed burning on 3.5 million acres, removing roadside fuel on 39,000 acres, and clearing and maintaining 11,000 miles of firebreaks.

While small areas of the outback consist of clay soils the majority has exceedingly infertile palaeosols.

While small areas of the outback consist of clay soils the majority has exceedingly infertile palaeosols.

Postal codes in Belgium consist of four digits which indicate regional areas, e. g. " 9000 " is the postal code for Ghent.

Since 1974, it has been a purely ceremonial style granted by royal charter to districts which may consist of a single town or may include a number of towns or rural areas.

Free-trade areas and agreements ( FTAs ) are cascadable to some degree — if some countries sign agreements to form a free-trade area and choose to negotiate together ( either as a trade bloc or as a forum of individual members of their FTA ) another free-trade agreement with another country ( or countries ) — then the new FTA will consist of the old FTA plus the new country ( or countries ).

Perth's metropolitan area is formally divided into a number of local government areas, which themselves consist of a large number of suburbs, extending from Two Rocks in the north to Rockingham in the south, and east inland to The Lakes.

The coastal areas consist of temperate rainforests and alder shrublands.

Typical Traveller starships consist of control space ( i. e. one or more bridges ), a central power plant, a maneuver drive for in-system travel, a jump drive for interstellar travel, and payload space ( weapons, living areas, etc .).

The districts in the north and in the centre consist mainly of historical buildings, the south of the city is dominated by larger areas of newer buildings.

These bodies consist of boards which advise ministers on particular policy areas.

Oslo is the only urban center that alone constitutes a county ; the remaining 18 counties consist of both urban and rural areas.

Regions consist of subregions that contain clusters of like areas that are distinctive by their uniformity of description based on a range of statistical data, for example demographic, and locales.

In some cases, comarques consist of rural areas and many small villages centering around an important town, where the people of the region traditionally go to shop or to sell their goods.

However, the field also can consist of all dirt, grass, artificial turf, or, in areas such as New York City, asphalt.

The higher areas consist of a sedimentary layer of gravelly soils, known as the Blackheath Beds, that spread through much of the south-east over a chalk outcrop — with sands, loam and seams of clay at the lower levels by the river.

The grounds consist of five areas: a traditional farm community of the 1870s, an 1890s progressive farmstead, an industrial sites complex, rural town, national peanut complex, and the Museum of Agriculture Center.
