Control Of Widely Recognized Distortion May Allow Greater Output At Sandia's Z Machine
2014-01-10 09:33:28

DOE/Sandia National Laboratories A surprising effect created by a 19th century device called a Helmholz coil offers clues about how to achieve controlled nuclear fusion at Sandia National Laboratories' powerful Z machine. A Helmholz coil produces a magnetic field when electrified. In recent experiments, two Helmholz coils, installed to provide a secondary magnetic field to Z's huge one, unexpectedly altered and slowed the growth of the magneto-Rayleigh-Taylor instabilities, an...

Sounds Of Space
2013-12-20 16:31:24

Lee Rannals for redOrbit.com - Your Universe Online A scientist from the University of Leicester is helping to reveal the sounds of space by using satellite data. Some areas of space are so quiet you can hear your heart beat, but there are other areas that have the capacity to be as noisy as places on Earth. A multimedia composer at the University’s Space Center decided to generate a few of the surprising Earth-like sounds one could find in space. Andrew Williams used data collected from...

A new study on electric discharge behavior under intense gravitational forces shows that its dynamic changes as gravity increases Arc discharges are common in everyday conditions like welding or in lightning storms. But in altered gravity, not as much is known about the behavior of electric discharges. For the first time, Jiří Šperka from Masaryk University, Czech Republic, and his Dutch colleagues studied the behavior of a special type of arc discharge, so-called glide arc, in varying...

Decades-old Mystery In Earth's Upper Atmosphere Solved

University of California - Los Angeles New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe. Discovering the processes that control the formation and ultimate loss of these electrons in the Van Allen radiation belts — the rings...

Plasma-assisted combustion could help make jets fly higher, faster and longer, according to work presented at APS Division of Fluid Dynamics Meeting Mix together air, fuel, and heat and you get combustion, the chemical reaction that powers most engines in planes, trains and automobiles. And if you throw in some ionized gas (plasma), it turns out, you can sustain combustion even in conditions that would otherwise snuff out the reaction: at low air pressure, in high winds or when there's low...

New Insights Into A Fusion Plasma's Transport Barrier Promise To Boost Future Reactor Performance
2013-11-13 15:52:11

American Physical Society In a collaborative effort, researchers in the United States and the United Kingdom have developed a new technique that will help them optimize the transport barrier, or pedestal, in fusion plasmas, which will be key to increasing future fusion power performance. This work has been recognized with the 2013 APS John Dawson Award for Excellence in Plasma Physics Research. The core of fusion plasmas must reach temperatures over 100 million degrees to enable ample...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:

  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
