Ah, no, Djor Kantos; Tara of Helium is for no laggard," and she threw him a sweet smile and passed on toward the assembling dancers with Gahan, Jed of far Gathol.
Liquid helium is supplied from Qatar Helium-2 production facility in Ras Laffan with a 20 years SPA to Iwatani Corporation.
Society's helium needs go far beyond making balloons float and voices sound squeaky: Helium is essential for scientific research and is a crucial component of MRI medical scanners' cooling systems.
Helium is used in many applications, including magnetic resonance imaging (MRI), fiber optics and semiconductor manufacturing, breathing atmospheres, balloons and leak detection.
Helium is an essential feedstock for numerous industrial, medical, scientific and commercial applications including nuclear power generation, magnetic resonance imaging, industrial fabrication and welding, fundamental sciences and research, fiber optics, space and defence applications, semiconductor manufacturing, and many other applications.
Helium is essential to many applications such as magnetic resonance imaging (MRI); fibre optics and semiconductor manufacturing; metallurgy; breathing atmospheres for deep diving or unique blood gas medical mixtures; lifting for high altitude scientific research balloons, blimps; and other advanced applications.
Helium is the second most common element in the universe.
Furthermore, recycle systems are easily installed, and when maintenance is performed on such a system, the ongoing supply of helium is maintained by providing bulk helium as a backup.
The system is capable of acquiring high-resolution NMR data when liquid helium is scarce.
Helium is the second element of the periodic table and is one of the most abundant elements in the universe, yet it is fairly rare on Earth.
A world shortage of liquid helium is expected to remain severe at least until the second half of 2013.
Helium is the only element that can remain at a sufficiently cold temperature to allow for the stable and uniform magnetic field the MRI scanners need to work.
