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.

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.

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.

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 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.

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.

NGC 2000. 0 ( also known as the Complete New General Catalog and Index Catalog of Nebulae and Star Clusters ) is a 1988 compilation of the NGC and IC made by Roger W. Sinnott, using the J2000. 0 coordinates.

It also includes galaxies smaller than 1. 0 arcminute in diameter but brighter than 14. 5 magnitude from the Catalogue of Galaxies and of Clusters of Galaxies ( CGCG ).

Awarded the Air Force Distinguished Flying Cross and the Air Medal with 7 Oak Leaf Clusters ; and for Undergraduate Pilot Training, recipient of the Commander's Trophy, the Flying Trophy, the Academic Trophy, and the Orville Wright Achievement Award ( Order of Daedalians ); also presented the Air Force Meritorious Service Medal ( 1978 ).

Clusters of craters also lay across the eastern and southwestern sections of the rim.

Besides various university institutions, non-university research institutions and industrial partners also play a important role throughout the Clusters.

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.

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.

All the drivers knew about the plates and they also knew about the big floppy straw hat with shredded edges, the kind natives in travel ads wear when they are out joyfully chopping cane.

I think that we are here also talking of the kind of fear that a young boy has for a group of boys who are approaching at night along the streets of a large city.

By `` image '' is meant not only a visual presentation, but also remembered sensations of any of the five senses plus the feelings which are immediately conjoined therewith.

it is true that they are also extremely dull.

The networks for military communications are one of the best examples of networks which not only must be changed with the changes in objectives but also must be changed with the addition of new machines of war.

We are also struck by the fact that this story of a boy's love for his mother does not offend, while the incestuous love of the man, Paul Morel, sometimes repels.

He and also Mr. Cowley and Mr. Warren have fallen to the temptation which besets many of us to read into our authors -- Nathaniel Hawthorne, for example, and Herman Melville -- protests against modernism, material progress, and science which are genuine protests of our own but may not have been theirs.

On December 21, the day that the Irish House of Commons petitioned for removal of Sir Constantine Phipps, their Tory Lord Chancellor, Molesworth reportedly made this remark on the defense of Phipps by Convocation: `` They that have turned the world upside down, are come hither also ''.

Very likely it will also include a recognition that the work we are reading reflects or `` belongs to '' some way of thought labelled as a `` school '' or an `` -ism '', i.e. a complex or `` syndrome '' of ideas occurring together with sufficient prominence to warrant identification.

Greek boys and girls also go for rock-and-roll, and the stations most tuned to are those carrying United States overseas programs.

They both measure literature by moral standards, and in their political writings both allow for censorship, but the differences between them are also significant.

We may further grant to those of her ( Poetry's ) defenders who are lovers of poetry and yet not poets, the permission to speak in prose on her behalf: let them show not only that she is pleasant but also useful to States and to human life, and we will listen in a kindly spirit ; ;

Occupational choices are also useful -- and interesting -- in bringing out clearly that values do not constitute the only component in goals and aspirations.

The students who are most willing to acquiesce in the suppression of civil liberties are also those who are most likely to be prejudiced against minority groups, to be conformist and traditionalistic in general social attitudes, and to lack a basic faith in people.

This finding is consistent also with the fact that student leaders are more likely to be supporters of the values implicit in civil liberties than the other students.

In this sense also, they are surely conformists.

Of course I hope Hal can also, but those hopes are much more faint ''.

The novel, which is not merely dystopian but also brilliantly satiric, describes a future America where one-sixteenth of the population, the men who run advertising agencies and big corporations, control the rest of the people, the submerged fifteen-sixteenths who are the workers and consumers, with the government being no more than `` a clearing house for pressures ''.

But I will also remind them that I have always been inclined to skepticism, to a kind of Laodicean lack of commitment so far as public affairs are concerned ; ;
