Recently, the utilization of infrared analysis of expired gas to monitor end-tidal carbon dioxide partial pressure (PETCO 2 ) during anesthesia has gained in popularity. In contrast to arterial blood gas analysis, PETCO 2 analysis is immediate and continuous. Mass spectrometry has also been used to measure PETCO, and has been found to correlate well with arterial carbon dioxide partial pressure...

A continuous flow system was used to study the interactions between carbon dioxide and ethylene in intact sunflower (Helianthus annuus L.) plants. An increase in the concentration of carbon dioxide above the ambient level (0.033%) in the atmosphere surrounding the plants increased the rate of ethylene production, and a decrease in carbon dioxide concentration resulted in a decrease in the rate ...

These are carbon capture and sequestra...

elevated atmospheric carbon dioxide and other green house gases have increased the earth temperature in recent century, which it affects all biochemistry cycles in soils. to examine the effect of atmospheric co2 concentration and temperature on n forms in soil solution in a calcareous soil, an experiment was conducted in a completely randomized design with factorial arrangement in the laborator...
