Although terrestrial CO2 concentrations, [CO2] are not expected to reach 1000 micromoles mol-1 for many decades, CO2 levels in closed systems such as growth chambers and glasshouses, can easily exceed this concentration. CO2 levels in life support systems in space can exceed 10000 micromoles mol-1 (1%). Here we studied the effect of six CO2 concentrations,(More)
BACKGROUND There are little data on the efficacy of antiemetics for treating postoperative nausea and vomiting (PONV) in patients who received prior PONV prophylaxis. METHODS In this retrospective database analysis, we compared the efficacy of ondansetron with that of promethazine for treating PONV in adults receiving general anesthesia who failed(More)
Seven growth chamber trials (six replicate trials using 0.035, 0.12, and 0.25% CO2 in air and one trial using 0.12, 0.80, and 2.0% CO2 in air) and three replicate greenhouse trials (0.035, 0.10, 0.18, 0.26, 0.50, and 1.0% CO2 in air) compare the effects of super-optimal CO2 on the seed yield, harvest index, and vegetative growth rate of wheat (Triticum(More)
Angiosperm plants were grown under either the present day 21 kPa O(2) atmosphere or 28 kPa, as estimated for the end-Cretaceous (100-65 MyBP). CO(2) was held at different levels, within the 24-60 Pa range, as also estimated for the same period. In C(3) Xanthium strumarium and Atriplex prostrata, leaf area and net photosynthesis per unit leaf area, were(More)
ECoG arousal response as elicited by deionized water and by several concentrations of sweet, salty, sour and bitter tasting substances, all applied intraorally, were studied in the awake restrained rabbit. The study was carried out on 17 chronic preparations of adult male animals (2.6 kg average body weight). Water as a stimulant was presented in 60 trials(More)
