They used carbon dating tests to authenticate the claim that the skeleton was 2 million years old.
New legislation aims to reduce carbon emissions.
The substance was identified as carbon.
Decline in soil organic carbon and total nitrogen in relation to tillage, stubble management and rotation.
The y-axis represents fraction total organic carbon remaining.
The cost of replacing carbon by growing trees is so high primarily because of the opportunity costs of foregoing agricultural production on prime cropland.
Finally, growing trees for energy would reduce another 2.2 tons of carbon per hectare in the village facility and 3.6 tons in the centralized facility.
The lung was inflated to higher mean volumes without having to use high peak airway pressures to maintain ventilation (oxygenation and carbon dioxide removal).
