Many people suffering from joint problems would like to overcome the often debilitating pain caused by worn down joints, but don’t know where to turn or how to start seeking treatment. That is why surgeons at The Florida Knee and Orthopedic Centers offer free MRI and x-ray evaluations. Clearwater, FL (PRWEB) September 30, 2013 Many people don’t seek treatment for their painful joints for the simple fact that they either don’t know where to start or they are afraid of what kind of...

World's Sharpest X-ray Beam Shines At DESY
2013-09-30 11:42:20

Deutsches Elektronen-Synchrotron DESY The world's sharpest X-ray beam shines at DESY. At the X-ray light source PETRA III, scientists from Göttingen generated a beam with a diameter of barely 5 nanometers – this is ten thousand times thinner than a human hair. This fine beam of X-ray light allows focusing on smallest details. The research groups of Professor Tim Salditt from the Institute of X-ray Physics and of Professor Hans-Ulrich Krebs from the Institute of Materials Physics of the...

Lee Rannals for redOrbit.com - Your Universe Online [ Watch the Video: Millisecond Pulsar with Magnetic Field Structure ] Scientists writing in the journal Nature say they have discovered a millisecond pulsar with a dual identity. The team used NASA's Swift and Chandra X-ray Observatory to find a pulsar that readily shifts back and forth between two mutually exclusive styles of pulsed emission, including one in X-rays and another in radio. Scientists say this discovery represents an...

coma cluster of galaxies

April Flowers for redOrbit.com - Your Universe Online In the Coma cluster of galaxies, a team of astronomers has discovered enormous arms of hot gas using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. These arms span at least a half a million light years. The scientists say they will provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the Universe held together by gravity. A...

At some point in elementary school you were shown that opposite charges attract and like charges repel. This is a universal scientific truth – except when it isn’t. A research team led by Berkeley Lab chemist Richard Saykally and theorist David Prendergast, working at the Advanced Light Source (ALS), has shown that, when hydrated in water, positively charged ions (cations) can actually pair up with one another. “Through a combination of X-ray spectroscopy, liquid microjets and first...

Abell 2142, also called A2142 and located in the constellation Corona Borealis, is an X-ray luminous galaxy cluster. Its creation is due to the merger between two galaxy clusters. It is one of the largest objects in the universe and is six million light years across. It holds hundreds of galaxies and enough gas to make a thousand more. The pressure fronts in the system have been traced in detail and are relatively cool 50 million degree Celsius. The central region is embedded in large...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...

X-ray Binaries -- X-ray binaries are a class of binary stars that are very luminous in X-rays. The X-rays are produced by matter falling from one component (usually a relatively normal star) to the other component, which is a neutron star or a black hole. The infalling matter releases gravitational potential energy, up to several tens of per cent of its rest mass as X-rays. (Hydrogen fusion releases about 0.7 per cent of rest mass) X-ray binaries are further subdivided into...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
