Different individuals respond differently to carbon dioxide (CO 2 ) levels in the local atmosphere. We aimed to determine whether brain activity changes with various CO 2 concentrations and whether this is correlated with heart rate and arterial oxygen saturation (SPO 2 ). We used electrocardiograms...
Indoor carbon dioxide (CO2) is a critical parameter in the design and control of ventilation, and in monitoring fresh air levels in buildings. Building occupants are primary sources for indoors CO2, and the rate at which CO2 is generated depends on the occupants' physical activities. In the pa...

In this connection, effectiveness of carbon dioxide (CO2, 99.9%) was studied as an alternative to methyl bromide under various exposure timings, 25 ± 1 °C, against different developmental stages of the almond moth, Cadra cautella, and red flour beetle, Tribolium castaneum. In case of C. ...
A field study was conducted to investigate the effect of different levels of dietary proteins (12 and 16%) and fat levels (3 to 5.5%) fed to beef cattle on gaseous emission (methane-CH4, nitrous oxide-N2O, carbon dioxide-CO 2 and hydrogen sulfide-H2S) from the pen surface. To evaluate...
Thermal chemistry of air dissociation on different levels: Thermodynamics and reaction kinetics of thermal air dissociation at high temperatures are now rather well known. Systematic sensitivity analysis leads to the conclusion that oxygen dissociation is the rate-limiting reaction. • Non-thermal chemi...

The aim of this experimantal study which is applied on rats, is to determine the differences on the clotting factors over the application of low and high intraabdominal pressure (IAP) values in different periods of time in carbon dioxide (CO2) pneumoperitoneum. Thirty rats were randomized into...
Oxygenation was assessed via oxygen saturation as measured by pulse oximetry (SpO2), and changes in lung ventilation were measured via alveolar gas volume (VA), alveolar minute volume (VA min), carbon dioxide (CO2) production (VCO2), mixed exhaled partial pressure of CO2 (PECO2), exhaled ...
The carbon cycle includes important fluxes of methane (CH4) and carbon dioxide (CO2) between the ecosystem and the atmosphere. The fluxes may acquire eithe
