It is defined as the ratio of the number of photons emitted to the number of photons absorbed.

Moreover, we require areas to absorb the waste emitted by our energy use.

Clearly, the idea that those who emitted more in the past should get more emission rights for the future is unacceptable.

If the high energy particles are emitted at the end of the acceleration procedure, e.g.

If the activity of the gene was restored, the frequency of emitted sounds also was restored.

The condition follows from the assumption that light is emitted and absorbed by atoms independently, and that the thermal equilibrium is preserved by interaction with atoms.

formula_1Meaning at a particular position and direction, the outgoing light (Lo) is the sum of the emitted light (Le) and the reflected light.

Perhaps even in the depths of Mongolia, you would have heard the dire warnings emitted by journalists.

High income countries emitted around 18 billion tons of CO2 this year roughly half of all global emissions.

In the first case, sound waves are emitted from the camera, and by measuring the delay in their reflection, distance to the subject is calculated.

Ground level ozone is created when common pollutants emitted by cars, power plants, oil refineries, chemical plants and other sources react in the atmosphere to sunlight.

The idea is to capture the carbon dioxide that is emitted in power plants and other big factories when fossil fuels are burned, thereby preventing it from entering the atmosphere.

For starters, until 2050, only a total of around 700 gigatons of carbon dioxide can be emitted into the atmosphere.

This new technology, called carbon capture and sequestration, can cut by 80 the carbon dioxide emitted during the production of electricity.

He waited a long time before trying to open it, but once he did the cask emitted a cloud of ash.

Plenty of carbon dioxide will be emitted into the atmosphere as the world s climate negotiators fly to and from the Montreal meeting.

The cost to automotive companies of installing equipment to neutralize the fumes emitted by diesel vehicles is also increasing, making it difficult to keep the price of the cars competitive.

The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature (hence the name).

Peculiar tunnels above the freeway, capable of absorbing the carbon monoxide emitted by automobiles, are already being tested on the roads in Great Britain.

It also released a carbon bomb At the height, the fires emitted more carbon dioxide on a daily basis than the entire U.S. economy.

Since infrared radiation is emitted by all objects based on their temperatures, according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination.

Their leaders have consistently pointed out that our current problems are the result of the gases emitted by the industrialized nations over the past century.

While Benin has emitted low levels of CO2 overall during the past decade, its emissions have kept rising in recent years, according to World Development Indicators, and the country is experiencing the effects of climate change.

The second big technology that could make a major difference is called carbon capture and storage. The idea is to capture the carbon dioxide that is emitted in power plants and other big factories when fossil fuels are burned, thereby preventing it from entering the atmosphere.

So whilst inventing the technology that would usher in the telecommunications revolution, Watson had discovered that the star at the center of our solar system emitted powerful radio waves.

For a moment the sound he emitted seemed to have startled Karenin, and he stopped but, after he had breathed twice, the whistling recommenced with fresh and calm regularity.

To the extent that we invest across sectors and regions to improve our carbon productivity (GDP per unit of carbon emitted), we will weaken the pollution constrain on global growth.

The environmentally sound manner for using fossil fuels in the future will involve capturing the carbon dioxide at the power plant before it is emitted into the atmosphere, and then disposing of it by somehow burying it in the ground.

The New York Post, a tabloid, emitted a stream of sensational reportage claiming that 12 people had been killed and that a Saudi national was under guard at a Boston hospital.

Although more greenhouse gases are emitted in the Northern than Southern Hemisphere this does not contribute to the difference in warming because the major greenhouse gases persist long enough to mix between hemispheres.

In a cap and trade system, the government sets total allowable national emissions of CO2 per year and requires any firm that causes CO2 emissions to have a permit per ton of CO2 emitted.

Developing nations especially China and India will be the main greenhouse gas emitters of the twenty first century but were exempted from the Kyoto Protocol because they emitted so little during the West s industrialization period.

An effect happens in the air, it's a corrupting effect of the sound the ultrasound in this case that's emitted, but it's so predictable that you can produce very precise audio out of that effect.

Perhaps even in the depths of Mongolia, you would have heard the dire warnings emitted by journalists. You would have distilled from these agonized noises that the report concluded that global warming is worse than we had imagined, and that we need to take swift and strong action right now.

Consider the social media buzz within minutes of the bombing. The New York Post, a tabloid, emitted a stream of sensational reportage claiming that 12 people had been killed and that a Saudi national was under guard at a Boston hospital.

Similarly, engineers have developed ways to capture the carbon dioxide that results from burning coal in power plants and store it safely underground. This new technology, called carbon capture and sequestration, can cut by 80 the carbon dioxide emitted during the production of electricity.

Moreover, we require areas to absorb the waste emitted by our energy use. Translating all these demands into a common unit of physical area gives us an opportunity to compare it with Earth s productive area and thus to get a sense of how sustainable we are.

IS, I.S., Is, is, or i.s.

Whatever is, is.

Is it prey? Is it predator? Is it mate?

What it is is intelligence is defined by prediction.

War is peace. Freedom is slavery. Ignorance is strength.

Is the information verifiable? Is it a hoax? Is it true? Is it what?

Why is is this important?
