The unit heats air at the bottom, reducing its relative humidity, and the natural tendency of hot air to rise brings this low humidity air into contact with the clothes.

They do this by reducing or eliminating completely the number of harmful particles in the air in the vicinity of the emitting source (but they do not target the source of the emission itself). 2) Domestic (or indoor) purifiers are often performed via a filter. This technique efficiently cleans the air coming out of the machine.

Indeed, the joint air monitoring network provides a foundation for the region to develop a sophisticated regional air management program.

In Shanghai, air pollution from an additional million gasoline powered cars would kill an estimated nine people each year.

This study is financed with resources from the World Bank, the European Union, and the Governments of the Netherlands and Brazil Cuba is developing research programmes on climate variability and change, air pollution and atmospheric chemistry, and terrestrial ecosystems and biodiversity.

When air rises, moist air cools at a lower rate than dry air.

There is no air conditioning in the hospital, no ventilators working, smog is penetrating everywhere, including the emergency room s operating theatre.

An air purifier is a device which removes contaminants from the air.

And, as a recent study shows, because China s coal fired power plants are so dirty, electric cars make the local air worse.

Of note were refinements to export control lists, including the addition of specific aerosol sprayers suitable for dispersal of biological agents.

With the collapse in 1991 of Air Europe in the aftermath of the 1990 91 Gulf War, the only other Trent powered MD 11 customer was lost.

Air detection

Air action

Air Cooler

This one we actually first discovered back in the air days the bad old air days, as we used to say when we were doing these kind of dives with air.

Moist air has more water vapor than dry air, so more latent heat is released into the parcel of moist air as it rises.

Houses in the Air

Air pollution

There's a convergence. So, wherever the rain is falling, the air is drawn towards it to replace the air that's rising.

Dry air does not have as much water vapor, therefore dry air cools at a higher rate with vertical movement than moist air.

It's acoustic vibrations in the air, little waves of energy in the air that tickle our eardrum.

This makes moist air generally less stable than dry air (see convective available potential energy).

He fights windmills.

The air conditioner was on.

The ratio of this air to the amount of air flowing through the engine core is the bypass ratio.

They function somewhat like a battery, except that their fuel is constantly replenished, reacting electrochemically with the air s oxygen to make electricity to drive an electric motor.

A dual hose unit draws air to cool its condenser from outside instead of from inside the room, and thus is more effective than most single hose units.

formula_4Where formula_5 is dynamic pressure.

Transport support base for the air staff.

Air pollution atmosphere

This in turn drew cooler air in from the lower vent, providing constant circulation of cooler air.

That is, for the same vertical movement, a parcel of moist air will be warmer than a parcel of dry air.

The weather front forms when the moist air over the Pacific meets the cooler continental air mass.

So we had to solve all the problems we had without air conditioning and with very poor power, so most of the solutions that came out used little blasts of air put at the right places to keep the machines running.

Many kinds of animals have vanished from the earth.

All hope of winning the game vanished.

Tear gas spreads through the air.

I was very scared.

That's because the bubble vanished into thin air.

If there is a warm layer of air higher up, an inversion can prevent thermals from rising high and the air is said to be stable.

The tendency of air and fire, on the other hand, was to move upwards, away from the center, with fire being lighter than air.

At some point, the force exerted by moving air upon the silk threads is great enough to launch the spider into the air.

As soon as it touches the water, you should hear a sort of sound of running air.
