Two thick birch partitions and a small air cavity create a well-insulated enclosure inside the cabinet, separating the midrange and tweeter from the woofers, further isolating woofer back-radiation.

They also conclude that greenhouse warming has partially been offset by the cooling effect of aerosols - tiny particles of dust thrown into the atmosphere that can reflect solar radiation back into space.
"The first thing that happens when we add carbon dioxide into the atmosphere is it radiates some extra radiation back down to the surface, and we warm up a little bit, " Kirk-Davidoff says.
Where the ice vanishes entirely, the surface loses its usual highly reflective whiteness - which sends most solar radiation back into space - and is replaced by darker waters instead which absorb more heat.
Later Tuesday the level of radiation fell back down again to 1 rem or less.
FORBES: Japan Radiation Fears May Outstrip The Real Health Dangers
For example, the bright snow- and ice-covered landscapes of Canada and Siberia during winter reflect most solar radiation straight back into space, keeping the surface cold.
Well, incoming solar radiation is reflected back out into space as well by the same processes.
FORBES: Climate Scientists Deepening Skepticism of Democracy
Parents say they are particularly concerned about bringing their children back because the health effects of radiation on the young are so unclear.
ECONOMIST: The mounting human costs of Japan��s nuclear disaster
She's still undergoing radiation therapy but is back at work.
Ironically, the company was once a vocal supporter of the laws now on the books outlawing back-scratching between doctors and radiation clinics, for fear that another clinic operator would cut them out of referral streams.
With more emotion than sense, electronic components, machine parts and even towels made far from Fukushima have required radiation checks or been turned back by Italy and China, among others.
Ms. SUZANNE THOMASSEN-KRAUSS (Textile Curator, Smithsonian Institution's Museum of American History): When you look at a lit object, what you're getting is only the light radiation that's reflecting back off the object.
One of the key technologies that is needed is a means to recycle water from astronauts back into a drinkable form, along with radiation shielding and developing ways of working and living in space for prolonged periods.
Ordinarily, there should come a point where the pressure from all the radiation emitted by a stellar behemoth pushes back against any further infall of gas and dust.
Mr. Nakamura said Meiji conducted radiation tests on March 21, which came back negative.
Well, a decade and more back, we used to import into Russia these very radiation hardened chips.
FORBES: Phobos-Grunt Falls From the Sky. Tim Worstall Not Blamed
The basic concept is the same as that underpinning the "white roads" idea -- the development of a technology that can reflect a proportion of the sun's radiation away from the earth's surface and back out into space, thereby cooling the atmosphere and slowing, or even reversing the damaging effects of global climate change.
CNN: The shield of Ra: Could solar reflection save the planet?
Most of it is, of course, radiated back into space. (It is the partial blocking of this radiation by gases such as carbon dioxide that causes the much-talked-of greenhouse effect.) Some of it, however, goes in the opposite direction, into the ground.
Radiation readings on Thursday showed levels in water in Tokyo had fallen back below the danger level, but the municipal authorities are distributing thousands of bottles of water to households with infants.
In addition to its weather-watching mission and collection of climate records, MSG-3 has a radiation sensor to measures the amount of solar and infrared energy that is reflected back into space, to better understand climate processes.
"For women who already have lymphedema, this is good news because we have not known how to get them back to moving and grooving again, " said Weiss, who is the director of breast radiation oncology and breast health outreach at Lankenau Hospital in Wynnewood, Pennsylvania.
For some who understand the biophysics of RF and EMF, going back to first principles provides a reality check on a possible threat from this low energy form of radiation.
Since NASA's Curiosity rover made its way to Mars, it's been sending back a wealth of data from our rust-colored planetary neighbor: landscape photos, radiation readings and even evidence of liquid water.
