Working ability between air and trimix breathing gas under 8 ATA air condition.

Health and efficiency in trimix versus air breathing in compressed air workers.

The Western Scheldt Tunneling Project in the Netherlands provided a unique opportunity to evaluate the effects of trimix usage on the health of compressed air workers and the efficiency of the project. Data analysis addressed 318 exposures to compressed air at 3.9-4.4 bar gauge and 52 exposures to trimix (25% oxygen, 25% helium, and 50% nitrogen) at 4.6-4.8 bar gauge. Results revealed three inc...

Gas exchange with air and water in an air-breathing catfish, Saccobranchus (Heteropneustes) fossilis.

Recent studies on air-breathing fish have shown that different species are adapted in varying degrees for gaseous exchange in both water and air. In the lungfishes these differences are correlated with different degrees of development of the gills, the efficiency of the lung in gas exchange, and the respiratory properties of the blood (Lenfant, Johansen & Grigg, 1966; Johansen & Lenfant, 1967, ...

Experimental and Numerical Investigation of Air Temperature Distribution inside a Car under Solar Load Condition

In this work both experimental and numerical analysis are carried out to investigate the effect of solar radiation on the cabin air temperature of Maruti Suzuki Celerio car parked for 90 min under solar load condition. The experimental and numerical analysis encompasses on temperature increment of air at various locations ins...

Gas and Air Analgesia

Palatine." It is also through the generosity of the editor of The British Dental Journal that I can publish Plate H from an article by the late Mr. A. T. Pitts. I cannot conclude this paper without expressing my gratitude to the anaesthetists, especially Dr. Geddes, for their cooperation in these operations. I should like to say how much the good results and low mortality have been contributed ...
