For regions with a "Moderate" level of pollution by EPA definition, a major source is one that emits
100 TPY, and is allowed six years for compliance.
In conclusion we found EMIT
to be a rapid, viable, and specific assay for measuring CsA concentrations in transplant recipients.

In newer work, the researchers have created a three-dot LED that can emit
red, blue, and green.
The Glenns Ferry Facility will be the first Biodiesel Plant in the World to emit
Near Zero net Global Warming Gases.
Lin says his group plans to develop tungsten photonic crystals that include, on a single microchip, both a heated region that emits
infrared radiation and another region that converts those thermal emissions into laserlike beams for driving telecommunications networks.
What makes the new laser truly a single-atom device, McKeever says, is that the atom remains confined long enough-roughly a tenth of a second--to emit
a beam of photons by itself.
The devices require very little electrical current to produce optical energy output of 850nm and above, and they emit
a narrow, circular beam that makes it easy to transmit the light into an optical fiber.
When electrons drop into those middle levels, they emit
photons with less energy, and therefore longer wavelengths, than usual.
These ions emit
a particular wavelength of blue light, 488.
Typically, lasers emit
light of one pure color, or wavelength.
Still, the work may spur researchers to pursue making lasers of deeply etched, or porous, silicon, which has been shown to emit
light in response to electric signals but not to amplify light, he says.
