The carbon dioxide leakage from chambers measured using sulfur hexafluoride
In plant chamber studies, if CO2 leaking from a chamber is not quantified, it can lead to an overestimate of assimilation rates and an underestimate of respiration rates; consequently, it is critical that CO2 leakage be determined. Sulfur hexafluoride (SF6) was introduced into the chambers as a tracer gas to estimate leakage rates. Chamber leakage constants were determined by measuring the rate...
متن کاملCarbon-isotopic composition of soil-respired carbon dioxide in static closed chambers at equilibrium.
The carbon-isotopic composition (delta13C) of soil-respired CO2 has been employed to evaluate soil carbon-cycling processes and the contribution of soil CO2 emissions to canopy and tropospheric air. These evaluations can be successful only when accurate isotope values of soil-respired CO2 are available. Here, we tested the robustness of delta13C values of soil-respired CO2 obtained after long i...
متن کاملUse of Carbon dioxide versus air blower in on-pump beating-heart coronary artery bypass surgery
Introduction: The use of carbon dioxide blower has been recognized as the standard of care in patients undergoing beating coronary artery bypass grafting (CABG) due to higher solubility and lower risk of embolization. On the other hand, the compressed air blower has gone out of use since air can be easily trapped and is less soluble which can cause coronary embolism. The prese...
متن کاملExperimental induction of left abomasal displacement: a new educational technique
The purpose of this study was to induce abomasal displacement to the left, and to let the undergraduate and post graduate students get used to the ping sounds of abomasum and other clinical manifestations. The procedure was carried out on eight young bulls, they were sedated and a 2 m flexible tube was inserted through the nasal canal into the rumen. By laparo-rumenotomy, 20 cm of the tube was ...
متن کاملA method for estimating carbon dioxide leakage rates in controlled-environment chambers using nitrous oxide
Naturally sunlit, outdoor controlled-environment chambers provide an important research tool for studying the effects of environmental variables on crop physiological processes. Typically these types of chambers are semi-closed and are capable of continuously monitoring canopy scale gas exchanges. Accurately determining chamber CO2 leakage rate is essential for correcting measurements of photos...
