The crown wheel gear is attached to the differential carrier or cage, which contains the ' sun ' and ' planet ' wheels or gears, which are a cluster of four opposed bevel gears in perpendicular plane, so each bevel gear meshes with two neighbours, and rotates counter to the third, that it faces and does not mesh with.

The pneumoniae group contains the clusters of M. muris, M. fastidiosum, U. urealyticum, the currently unculturable haemotrophic mollicutes, informally referred to as haemoplasmas ( recently transferred from the genera Haemobartonella and Eperythrozoon ), and the M. pneumoniae cluster.

Members of higher and lower social status often cluster around this nucleus, so that Protestant figures on social class give the impression of spread over all social classes ; ;

It is also the most luminous globular cluster in the Milky Way, at over one million solar luminosities.

The average separation between galaxies within a cluster is a little over an order of magnitude larger than their diameter.

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.

* 1995 – During the Croatian War of Independence, Serb forces fire cluster bombs at Zagreb, killing 7 and wounding over 175 civilians.

The timescale over which a cluster disrupts depends on its initial stellar density, with more tightly packed clusters persisting for longer.

Open clusters become disrupted over time by the gravitational influence of giant molecular clouds as they move through the galaxy, but cluster members will continue to move in broadly the same direction through space even though they are no longer gravitationally bound ; they are then known as a stellar association, sometimes also referred to as a moving group.

With a cluster of car-makers and parts suppliers, the Turkish automotive sector has become an integral part of the global network of production bases, exporting over $ 22, 944, 000, 000 worth of motor vehicles and components in 2008.

Because utilitarianism is not a single theory but a cluster of related theories that have developed over two hundred years criticisms can be made for different reasons and have different targets.

A special case of process VMs are systems that abstract over the communication mechanisms of a ( potentially heterogeneous ) computer cluster.

Its principal city is Lille, which with nearby Roubaix, Tourcoing and Villeneuve d ' Ascq constitutes the center of a cluster of industrial and former mining towns totalling slightly over a million inhabitants.

Old buildings originating from all over the region have been moved here to form a typical cluster of farm buildings including " open hearth " houses, sheds, outhouses, smokehouses and a small chapel.

Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster ( hence the alternate name Maia Nebula after the star Maia ), but is now known to be an unrelated dust cloud in the interstellar medium that the stars are currently passing through.

Yet some authors argue that the controversy over the distance to the Pleiades discussed below is a red herring, since the cosmic distance ladder can ( presently ) rely on a suite of other nearby clusters where consensus exists regarding the distances as established by Hipparcos and independent means ( e. g., the Hyades, Coma Berenices cluster, etc.

It was formerly thought that the dust was left over from the formation of the cluster, but at the age of about 100 million years generally accepted for the cluster, almost all the dust originally present would have been dispersed by radiation pressure.

Because cluster bombs release many small bomblets over a wide area they pose risks to civilians both during attacks and afterwards.

The mountain has also suffered under a massive onslaught of invasive alien plants for well over a century, with perhaps the worst invader being the cluster pine.

Many of these homes were constructed with a brick-veneer ground story over basement in variations of the cape style to the south and east of Hempstead Turnpike, while older, smaller shingled homes cluster near the racetrack.

Considering that over half of the Earth's land mass consists of areas inhospitable to human inhabitation, such as deserts and high mountains, and that population tends to cluster around seaports and fresh water sources, this number by itself does not give any meaningful measurement of human population density.

* Convention on Cluster Munitions, is an international treaty that prohibits the use of cluster bombs, a type of explosive weapon which scatters submunitions (" bomblets ") over an area.

The Rosette Nebula, over 100 light-years in diameter, has an associated star cluster and possesses many Bok globules in its dark areas.
