We compared the Beckman Cl/CO2 Analyzer to the American Instrument Company chloride titrator for measurement of chloride in serum, sweat, and spinal fluid. We also compared it to the Natelson gasometer and a modified continuous-flow (AutoAnalyzer) technique for measurement of carbon dioxide in serum. Effects of bilirubin and hemoglobin on results for both the CO2, and Cl were negligible. The li...

All luminous animals require oxygen for luminescence bu t it is not known whether they give off CO2 as a result of the luminescence. Luminous bacteria produce carbon dioxide but this is no doubt the carbon dioxide of respiration. Even if we could prove that luminous bacteria produced more carbon dioxide than certain non-luminous bacteria, this would not necessarily znean that the excess carbon ...

PURPOSE Respiratory acidosis during carbon dioxide (CO2) insufflation has been suggested as a cause of spontaneous abortion and preterm labour following laparoscopic cholecystectomy during pregnancy. Capnography may not be adequate as a guide to adjust pulmonary ventilation during laparoscopic surgery and hence arterial carbon dioxide (PaCO2) monitoring has been recommended. We report the feasi...

drought, ultraviolet radiation and atmospheric co2 are some three environmental factors that seriously affect future food security. the objective followed in the present research was to study the effect of two levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv a, b and c with intensities of 18, 25 and 40 microw.cm-2 respectively) and water deficit (%100 and %60 of field capac...

In this work, the effect of carbon dioxide partial pressure on the calcination kinetics of high purity zinc carbonate hydroxide has been studied. Non-isothermal analysis has been performed on samples at different CO2 partial pressures by TGA and DTA. It has been found that the calcination behaviour of this material corresponds to the shrinking core model and the reaction mechanism is phase boun...

The estimated diffusion fluxes of methane (CH4) and carbon dioxide (CO2) at the sediment-water interface in the Rzeszów Reservoir in southeastern Poland are presented. The relevant studies were conducted during 2009, 2010, and 2011. Calculated fluxes ranged from 0.01 to 2.19 mmol m-2 day-1 and from 0.36 to 45.33 mmol m-2 day-1 for methane and carbon dioxide, respectively. While the values for c...

The upper airway (UA) of adult animals is known to contain carbon dioxide-sensitive receptors and UA CO2 reflexly affects breathing, UA dilator muscle activity and UA resistance. These effects may function in the control of UA patency. There is evidence that some UA reflexes are stronger in young than in adult animals, but it is not known whether CO2-sensitive receptors are present in the UA of...

Terrestrial plant and soil respiration, or ecosystem respiration (Reco ), represents a major CO2 flux in the global carbon cycle. However, there is disagreement in how Reco will respond to future global changes, such as elevated atmosphere CO2 and warming. To address this, we synthesized six years (2007-2012) of Reco data from the Prairie Heating And CO2 Enrichment (PHACE) experiment. We applie...

The role of carbon dioxide in global warming is one of the contemporary environmental issues and it is, therefore, necessary to have available technology to capture the released CO2 into the atmosphere. Amino acids have the same amine functionality as alkanolamines with similar behavior towards CO2 absorption. The solubility of carbon dioxide in potassium glycinate (KG) solutions with different...

In this paper, we examine the potential of carbon capture and sequestration technologies to make a significant contribution to national and global efforts to control carbon dioxide (CO2) emissions. We examine the performance of these technologies under two alternative future energy-policy scenarios. We conclude that carbon capture and sequestration technologies could indeed play a significant r...
