Metamaterial Aims To Redefine Printed Circuit Boards
2012-10-20 08:05:13

April Flowers for redOrbit.com — Your Universe Online It's probably a safe bet that you have never been in a big electronics retailer like Best Buy or Comp USA and seen a sign boasting the percentage of recycled electronic components that a laptop or smart TV uses. This suits the electronics industry, as many of the leading companies make their money selling more and more new components. A new technology from Oxford University, however, may just change this paradigm forever....

Earth Surface: A Giant Loudspeaker
2012-10-19 12:56:13

Brett Smith for redOrbit.com — Your Universe Online In the midst of an earthquake, buildings sway back and forth, terrain pops and locks, and the ground seems to shuffle underfoot. Acoustic scientists have shown in a new study that the Earth´s surface and atmosphere act as a giant loudspeaker. This “loudspeaker” soundtracks these geologic raves in both the audible range of hearing and in infrasound, or frequencies below the range human hearing can detect....

Invisibility Cloaking For Better Electronics
2012-10-13 05:18:13

Lee Rannals for redOrbit.com - Your Universe Online The power of cloaking mechanisms could eventually lead the way for developing more efficient thermoelectric devices and new kinds of electronics. MIT researchers applied the idea of harnessing the cloaking mechanisms developed to shield objects from view, to the movement of electrons. Previous work relied on metamaterials made of artificial materials with unusual properties. The composite structures used for cloaking cause light...

Underwater Noise Pollution Impedes Whale Communications
2012-08-16 06:01:53

April Flowers for redOrbit.com - Your Universe Online Noise pollution is a problem that plagues us all. Loud cars and trucks, music, airplanes and more create a constant cacophony we have to learn to block out of our conscious mind in order to deal with our lives. However, we aren't the only ones suffering from too much noise. According to a paper published in Conservation Biology, high levels of background noise, mainly due to ships, have reduced the ability of critically endangered...

UC Research Promises Reduced Noise In Automobiles
2012-08-14 12:52:33

UC research featuring a mathematical model for quick-response, noise-cancellation designed to minimize sudden and unexpected noise caused by road hazards — bumps or potholes for example — will be presented in New York City Aug. 19-22. All noise is not necessarily equal — especially when it comes to sound minimization in automobiles. For instance, automakers have long used sound-absorbing materials (passive control) in the design of cars in order to minimize engine...

A tuning fork, formed of a two-pronged fork, is an acoustic resonator with prongs formed from a U-shaped bar of elastic metal. When struck against a surface it resonates at a specific constant pitch emitting a pure musical tone after waiting a moment for some high overtones to die out. The length of the prongs determines the particular pitch of the fork. Most of the time it is used as a standard of pitch to tune other musical instruments. In 1711, John Shore invented the tuning fork. The...

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
