A trace gas is a gas which makes up less than 1 by volume of the Earth's atmosphere, and it includes all gases except nitrogen (78.1 ) and oxygen (20.9 ).

(i) Transport of gases (harmonization and standardization)

The membrane must also not allow either gas to pass to the other side of the cell, a problem known as gas crossover.

The hot diffuse gas in the Local Bubble emits X rays.

In regenerative preheating, the exhaust gases from the furnace are pumped into a chamber containing bricks, where heat is transferred from the gases to the bricks.

These may be further subdivided as problems of

(e) This special classification would occur only when more severe organ systemic effects including in the respiratory system are not observed.

It has a side arm fitted with a PTFE or ground glass stopcock which allows the vessel to be evacuated or filled with gases (usually inert gases like nitrogen or argon).

Greenhouse gas (GHG) accounting can calculate direct or indirect GHG emissions, which may be used for internal reporting or enterprise carbon accounting.

It can be used, for example, to trace the flow of gases within the lungs.

Greenhouse gas emissions are the archetypal case.

The main greenhouse gas is carbon dioxide.

The ideal gas law is the equation of state of a hypothetical ideal gas.

The stoma complex regulates the exchange of gases and water vapor between the outside air and the interior of the leaf.

Chinarejects India s argument that per capita emission levels and historic contributions of greenhouse gases should form the objective criteria for carbon mitigation.

I had to wear a gas mask because of the toxic fumes I guess, except for in this picture.

Greenhouse gases, for example, are global problems. While America says that it cannot afford to do anything about it, China s senior officials have acted more responsibly.

These gases, particularly CO2, increase the risk of damage to the world s climate.

Yet emissions are not just rising, but accelerating.

In chemistry, Henry's law is one of the gas laws formulated by William Henry in 1803.

An explosimeter is a gas detector which is used to measure the amount of combustible gases present in a sample.

3.10.1.6.2 While a methodology for determination of aspiration hazard in animals has been utilized, it has not been standardized.

Adjustment methods based on correlation of emissions removals between categories or gases

Carbon emissions have kept increasing, despite repeated promises of cuts.

An alternate explanation for noise is the bubbling of escaping gases from natural decomposition of bodies.

Adjustment methods based on correlation of emissions removals between source categories or gases

In Figure 2.1.1, in the title, after class 1 insert for transport replace the box reject unstable explosive with classify as an unstable explosive and replace the box accept into Class 1 with Classify as an explosive

3.10.1.6.1 A review of the medical literature on chemical aspiration revealed that some hydrocarbons (petroleum distillates) and certain chlorinated hydrocarbons have been shown to pose an aspiration hazard in humans. Primary alcohols, and ketones have been shown to pose an aspiration hazard only in animal studies.

Yet, since that time, greenhouse gas emissions have continued to soar.

Trench warfare dominated strategy on the Western Front, and the use of chemical and poison gases added to the devastation.

The function of the allantois is to collect liquid waste from the embryo, as well as to exchange gases used by the embryo.

b. Continue the work on toxic gas mixtures (TGM) (in cooperation with OECD)

2.1.4.1 In the last but one sentence, replace in Division 5.1 with as an oxidizing liquid (Chapter 2.13) or an oxidizing solid (Chapter 2.14) and in the last sentence replace 2.1.3 with 2.1.4

It's got all the valves and knobs and things you need to do to inject the right gases at the right time.

So reducing emissions today is very valuable to humanity in the distant future.

Volcanic gases include a variety of substances given off by active (or, at times, by dormant) volcanoes.

Well, in gasses, atoms move past each other so fast that they can't hitch up.

Abundances of heavier inert gases in Jupiter's atmosphere are about two to three times that of the Sun.

For the first six periods of the periodic table, the noble gases are exactly the members of group 18 of the periodic table.

In such cases, the universal gas constant is usually given a different symbol such as R to distinguish it.

The flow of the furnace is then reversed so that fuel and air pass through the chamber and are heated by the bricks.

AB32 requires the state to cut greenhouse gas emissions by 30 percent by 2020.

At the 1925 Geneva Conference for the Supervision of the International Traffic in Arms the French suggested a protocol for non use of poisonous gases.

A baseline shall cover emissions from all gases, sectors and source categories listed in Annex A within the project boundary.

So while I'm talking to you, the seats you are sit on are currently emitting some invisible and odorless toxic gas. Sorry for that.
