It is further defined as an activity that includes one or more of the following diving beyond 40 meters 130 feet, required stage decompression, diving in an overhead environment beyond 130 linear feet from the surface, accelerated stage decompression and or the use of multiple gas mixtures in a single dive.

In technical diving, the diver may carry different equipment for different phases of the dive some breathing gas mixes may only be used at depth, such as trimix and others, such as pure oxygen, which only may be used during decompression stops in shallow water.

America s rapid switch to natural gas is the result of three decades of technological innovation, particularly the development of hydraulic fracturing, or fracking, which has opened up large new resources of previously inaccessible shale gas.

Rapid global demand for electricity, increasing uncertainty in supply and prices of oil and natural gas, and concerns about the greenhouse gas emissions have opened more prospects for the new development of nuclear energy at the global scale.

This lets them stay underwater longer for the same decompression requirement as for air, because less nitrogen is absorbed into the body's tissues.

Their values vary from gas to gas.

Although Kazakhstan, Uzbekistan, and other Central Asian countries have resumed rapid economic growth, much of their recent progress simply correlates with surging world oil and gas prices.

So I have methane gas plus oxygen gas yields carbon dioxide gas plus water.

The Bahrain National Gas Company operates a gas liquefaction plant that utilizes gas piped directly from Bahrain's oilfields.

aggregate greenhouse gas emissions and removals by gas and by sector

It will cut your gas prices in half, your gas bill.

Gas is a similar issue. Gas is also a biological product.

And as you think of gas, well, you're familiar with gas.

The Central European Gas Hub (CEGH) is established as an important gas trading platform on the gas routes from East to West and also operates a gas exchange.

It is now clear that avoiding catastrophic climate change requires dramatic and rapid reductions in greenhouse gas emissions, cuts that would lower annual emissions to 80 below 1990 levels by 2050.

In hot gas (gas turbine), turbines are driven directly by gases produced by the combustion of natural gas or oil.

The Commission also provides its questionnaires on gas to the International Gas Union for use in its gas statistics publication.

Rapid movement, contrast.

Rapid, because we wanted them to be served by rapid transport vehicles.

Efforts are being made to use the gas obtained during coal mining as fuel and legally to prohibit leaks during natural gas development and fugitive gas from gas works.

I smell gas.
