The plants were grown in glasshouse experiments at ambient and elevated carbon dioxide
"The demand for carbon dioxide
is very, very large," said Steve Melzer, the Midland-based president of the Texas Carbon Capture and Storage Association.
Measurements concerning carbon dioxide
showed Mars is a much more active planet than previously thought.
The volume of groundwater-generated carbon dioxide
is, at most, a small percentage of the emissions produced by burning fossil fuels, says Macpherson.
Which of the shown sources contribute more than 10 percent of the total amount of carbon dioxide
released each year.
The researchers acknowledge that plants do play a role in mitigating global warming, with about half of the carbon dioxide
emitted into the atmosphere stored, at least temporarily, by ecosystems.
* Is carbon dioxide
a consequence, rather than a driver, of global warming?
Use this equation to calculate the number of trees needed to absorb the carbon dioxide
released each year from the use of certain appliances: (kilograms of carbon dioxide
released) / (11 kilograms of carbon dioxide
absorbed per tree) = number of trees.
DNP's fermentation method differs from that created by Bennett and San in that an aerobic process occurs first, followed by an anaerobic process that requires added carbon dioxide
. Says Berglund, "We take six carbons from glucose and add two carbons from carbon dioxide
to form two molecules of succinate with four carbons each."
-- Carbon dioxide
and gadolinium are alternative contrast agents for imaging blood vessels in patients who can't tolerate conventional, iodinated contrast.
* Carbon dioxide
(C[O.sub.2]): common uses--refrigerants (storing and transporting ice cream); fire extinguishers; carbonated soft drinks; dry ice; inflating life jackets; foamy plastics; in nature--given off when animals (including humans) exhale
Even more significant, several electricity generators were, for the first time, contemplating capping emissions of carbon dioxide
, the principal greenhouse gas implicated in global warming.
Companies and residents are being urged to pay a `tariff' to the city council every time they pump carbon dioxide
into the atmosphere.
Department of Energy's Los Alamos National Laboratory are studying a simple, cost-effective method of extracting carbon dioxide
directly from the air.
is necessary for plants to perform photosynthesis.
