So we also need noise reduction at the emission sources.

Large-area field emission sources have been of interest since the 1970s.

Where low emissions sources are available, net production of pollutants can be reduced.

A second example of the need to target the correct emission sources relates to traffic.

My sensors detect a faint emissions source at 075 degrees.

Their generators aren't moving, they're just reshaping the main emission source.

"And nobody was looking for this particular emission source.

Wave energy is a renewable, high availability, zero emission source of power.

Regional pollutants cause damage further from the emission source.

She added, "They've gone after most of the large emissions sources, and off-road vehicles certainly deserve a close look."

He walked around the pool to the wall where the nearest of the emission sources had been and examined the area with his tricorder.

The new system appears to have two broad-spectrum sources embedded in a single narrow-band emissions source.

Calculating a basic carbon footprint that includes the main emission sources is straightforward.

There is a fine balance between providing the ability to capture all potential emission sources/actions and keeping the calculator easy to use.

Here's how an amplified spontaneous emission source works.

For sea-going mobile emission sources - ships - we also believe that the idea is somewhat premature.

From the 1950s onwards, extensive effort has been devoted to the development of field emission sources for use in electron guns.

At the end of the compliance period, emission sources must have enough allowances to cover their emissions during the period.

Other greenhouse gas emission sources, such as suppliers of transportation fuels, must comply with the cap beginning in 2015.

I detect two new emission sources.

To apply this strategy to numerous small-scale emission sources such as heating in homes and motor vehicles would be more complex.

The emission sources available to Hertz and Lennard in the 19th century shared that characteristic.

In general, the smaller the diameter of the emission source, the faster the variation in flux, and vice versa.

This approach assumes that an ambient air sample has particulate matter contributions from a linear combination of emission sources.

Air Emission Sources - Summarizes particulate matter emissions by source at national, state and local levels.
