Studies on degassing efficiency of nitrogen-chlorine gas mixtures

Generation of Nitrogen-Chlorine

Human phagocytes can be triggered to generate large quantities of long-lived nitrogen-chlorine derivatives. This class of oxidants can be detected as early as 5 min after the addition of phorbol myristate acetate or opsonized zymosan particles. Unlike all other oxygen metabolites known to be generated by phagocytes, the nitrogen-chlorine compounds can be readily detected in cell supernatants 90...

Inhalation of chlorine gas.

The clinical features of acute chlorine gas inhalation, and its management are reviewed. Current medical views on the chronic effects of an acute overwhelming exposure on lung function (reactive airways dysfunction syndrome), and the more controversial field of lung disease secondary to repeated inhalations of lower concentrations of chlorine gas are discussed.

Respiratory effects of chlorine gas.

Photochemical ozone and nitric oxide formation in air--nitrogen dioxide mixtures containing sulfur dioxide or chlorine.

Experiments were performed to investigate the effects of sulfur dioxide (O-10 ppm) and chlorine (O-15 ppm) on ozone and nitric oxide concentrations in irradiated mixtures of nitrogen dioxide (1-5 ppm) and air. The mixtures were irradiated by ultraviolet fluorescent lamps while flowing at a steady speed through a 9 m long, 15.2 cm i.d. Pyrex tube. The presence of sulfur dioxide produced no measu...

Studies of Helium Gas Mixtures in Drift Chambers*

Some properties of gas mixtures, composed predominately of helium and lesser amounts of CO2 and isobutane, were measured in a prototype drift chamber. The studies are motivated by the desire to reduce the multiple scattering inside the drift chamber at future high-luminosity, low-energy facilities such as 4 factories, T/charm factories, and B factories. The low atomic number of helium greatly r...
