Ventilation Efficiency and Carbon Dioxide (CO2) Concentration

In animals metabolic processes, involve complex organic molecules being broken down to simpler molecules, such as carbon dioxide and water. Carbon dioxide waste is removed from the body through respiration. Carbon dioxide content in fresh air is approximately 400 parts per million. In this study, we investigate the relationship between ventilation efficiency and carbon dioxide (CO2) concentrati...

Selective Carbon Dioxide Adsorption from N2- Ch4-co2 Mixture on Carbon Molecular Sieves

Cărbunii sită moleculară sunt adsorbanţi carbonici de o mare importanţă. Lucrarea prezintă rezultatele studiului privind prepararea cărbunilor sită moleculară şi modificarea tratamentului cu hidrocarburi care crachează. De asemenea se prezintă procesul de adsorbţie selectivă a dioxidului de carbon din amestecul N2-CH4-CO2 care se realizează într-un echipament special creat în acest scop, bazat ...

The alkenone-CO2 proxy and ancient atmospheric carbon dioxide.

Cenozoic climates have varied across a variety of time-scales, including slow, unidirectional change over tens of millions of years, as well as severe, geologically abrupt shifts in Earth's climatic state. Establishing the history of atmospheric carbon dioxide is critical in prioritizing the factors responsible for past climatic events, and integral in positioning future climate change within a...

Soil carbon dioxide fluxes in natural and CO2-enriched systems

Carbon dioxide fluxes between the soil and atmosphere were determined on the 1991 free-air carbon dioxide enrichment (FACE) experiment at the Maricopa Agricultural Center, Maricopa, Arizona. The study was conducted on drip-irrigated cotton in conjunction with other physical and physiological measurements. Fluxes were measured with a 1.6 1 closedchamber static sampling system. The main treatment...
