Some combination of the above-mentioned ideas may explain the formation of the cores of gas giant planets such as Jupiter and perhaps even Saturn.

If the skin is too thin, then the molded part will tend to shrink onto the cores that form them while cooling, and cling to those cores or part may warp, twist, blister or crack when the cavity is pulled away.

This depth may range between a few to several tens of meters to typically 100 m for Antarctic cores.

Although the ice cores from Quelccaya ice cap only go back ~ 2 ka, others may go back ~ 5. 2 ka.

They may contain coaxial cores for video, twisted pair for data or low voltage cores for mains power.

The ideal system uses multipins to connect the subsnakes to the main stage box ( which may be rack mounted ) and multipins to the main cores.

The primary benefits over rifled barrels is reduced barrel wear, longer ranges that can be achieved ( due to the reduced loss of energy to friction and gas escaping around the projectile via the rifling ) and larger explosive cores for a given caliber artillery due to less metal needing to be used to form the case of the projectile because of less force applied to the shell from the non-rifled sides of the barrel of smooth bore guns.

These pulsar planets are believed to have formed from the unusual remnants of the supernova that produced the pulsar, in a second round of planet formation, or else to be the remaining rocky cores of gas giants that somehow survived the supernova and then decayed into their current orbits.

In the laboratory, stratigraphers analyze samples of stratigraphic sections that can be returned from the field, such as those from drill cores.

It is more transparent to far-infrared, which can be used to observe the interior regions of giant molecular clouds and galactic cores in great detail.

Mathematically, the potential of the ion cores can be treated by various models, the simplest being the nearly free electron model.

Fully half of MIPS ' income today comes from licensing their designs, while much of the rest comes from contract design work on cores that will then be produced by third parties.

These cores can be mixed with add-in units such as FPUs, SIMD systems, various input / output devices, etc.

MIPS cores can be found in newer Cisco, Linksys and Mikrotik's routerboard routers, cable modems and ADSL modems, smartcards, laser printer engines, set-top boxes, robots, handheld computers, Sony PlayStation 2 and Sony PlayStation Portable.

6809 cores are available in VHDL and can be programmed into FPGA and used as an embedded processor with speed ratings up to 40 MHz.

It used to be that developers needed to code their programs in such a way that their software would explicitly take advantage of the multiple cores, which could easily become a tedious and troublesome task, especially in complex software.

Neutronium is used in popular literature to refer to the material present in the cores of neutron stars ( stars which are too massive to be supported by electron degeneracy pressure and which collapse into a denser phase of matter ).

* There is considerable uncertainty over the composition of the material in the cores of neutron stars ( it could be neutron-degenerate matter, strange matter, quark matter, or a variant or combination of the above ).

Most pencil cores are made of graphite mixed with a clay binder, leaving grey or black marks that can be easily erased.

If the mass of the core exceeds the Chandrasekhar limit, electron degeneracy pressure will be unable to support its weight against the force of gravity, and the core will undergo sudden, catastrophic collapse to form a neutron star or ( in the case of cores that exceed the Tolman-Oppenheimer-Volkoff limit ), a black hole.

Eddy current losses can be reduced by making the core of a stack of plates electrically insulated from each other, rather than a solid block ; all transformers operating at low frequencies use laminated or similar cores.

The rockbox project further extended this codec to be suitable for embedded cores, allowing playback on portable MP3 players and cell phones running open source software.

A reconstruction based on ice cores found the Medieval Warm Period could be distinguished in tropical South America from about 1050 to 1300, followed in the 15th century by the Little Ice Age.

These type of cores often take little silicon to implement, so they can be easily realized in an FPGA or in a multi-core form.

:* Pollen has been observed in the ice cores and can be used to understand which plants were present as the layer formed.

Given the low cost of the materials and manufacturing methods, inexpensive magnets ( or non-magnetized ferromagnetic cores, for use in electronic components such as radio antennas, for example ) of various shapes can be easily mass-produced.

Vector processor ( SIMD ) cores can be combined with VLIW architecture as the Fujitsu FR-V, further increasing throughput and speed.

By January 2008, over 10 billion ARM cores had been built, and in 2008 iSuppli predicted that by 2011, 5 billion ARM cores will be shipping per year.

After approximately two years of further research and development, they were able to demonstrate a core plane that was made of 32 by 32, or 1024 cores, holding 1024 bits of data.

Bipolar percussion is often used to break open small cobbles, or to have a second chance with spent lithic cores, broken bifaces, and tools that have been reworked so much that it is impossible to make further useful tools using traditional lithic reduction.

Bifacial cores are usually further reduced into trade bifaces, biface blanks, or bifacial tools.

As cities expanded, people built further away from the water and their historical cores, often uphill.

Once distinctly and fiercely independent of Los Angeles and San Francisco, the area has seen increasing exurban development as the cost of living forces young families and small businesses further and further away from the coastal urban cores.

Sampling thick glaciers and ice sheets to obtain ice cores is related but will not be described further here.
