water by the latter alone, although it is known to manufacturers that sweet drinks require much less carbon dioxide than soda-water. The chief complaint about their soda-water was that it did not hold as much carbon dioxide in solution as some of the best soda-waters placed on the market by other manufacturers. The company employs the latest method of manufacture. Carbon dioxide is generated by...

Carbon Dioxide Sequestration Part 1— Field Studies The Gas Technology Institute with support from Illinois Clean Coal Institute and cooperation of the Illinois State Geological Survey designed and implemented a comprehensive research project aimed at determining the viability of seismic techniques for site selection and monitoring of carbon dioxide sequestration in Illinois coals. Editor’s note...

Northern Hemisphere's carbon dioxide emissions. "That's much more than any terrestrial plant ecologist would have considered likely," Tans said. Conserving tree and plant populations, he added, might raise their carbon dioxide uptake even higher. Understanding how carbon cycles through plants is vital to decreasing global warming. By burning fuel and clearing forests, human activity generates 7...

HE inhalation of radioactive oxygen (0 ir ') with external chest counting allows the measurement of regional ventilation and oxygen uptake in the lung. 1 The subject inhales a measured volume of air containing a minute amount of oxygen-15 and holds his breath for 10 to 15 seconds. The initial peak counting rate is determined by the ventilation of the core of lung tissue between the counters, an...

Acute lung injury and acute respiratory distress syndrome are characterized by a non-cardiogenic pulmonary edema responsible for a significant impairment of gas exchange. The pulmonary dead space increase, which is due primarily to an alteration in pulmonary blood flow distribution, is largely responsible for carbon dioxide retention. Previous studies, computing the pulmonary dead space by meas...

BACKGROUND Various pediatric conditions often necessitate a morphologic examination of the hip joint in infancy or childhood, and multiple imaging options have been employed to achieve this goal. Arthrography is one such modality. Different types of contrast media have been utilized and include pharmacologic contrast agents, air, and carbon dioxide. There are scattered reports of complications ...

We report the combined use of heliox and high-frequency jet ventilation to augment carbon dioxide clearance, with a focus on the important technical considerations. Our case is a 5-month old infant with acute respiratory failure associated with gas trapping, hypercarbia, respiratory acidosis, and air leak. Despite maximal conventional ventilation, bronchodilator therapy, corticosteroids, and se...

Methane and nitrous oxide emissions from a fully covered municipal wastewater treatment plant were measured on-line during 16 months. At the plant under study, nitrous oxide contributed three-quarters to the plant's carbon footprint, while the methane emission was slightly larger than the indirect carbon dioxide emission related to the plant's electricity and natural gas consumption. This contr...

A trace amount of carbon was determined by atmospheric-pressure helium microwave induced plasma atomic emission spectrometry (He-MIP-AES) with gas-phase sample introduction technique. This method was applied for the generation of a continuous flow of carbon dioxide by the acidification of carbonate ion and hydrogen carbonate ion for the determination of carbon. The generated carbon dioxide was ...
