Plant breeding continues to provide fresh produce industries with new varieties that may have different characteristics for temperature and shelf life management. Controlled Atmosphere. Almond moisture should be maintained at 6% or less. In particular, the concentration of carbon dioxide is reduced and that of oxygen is increased. 4 μmol-O/g cat are obtained that are equivalent to about five oxygen monolayers. Hexagonal YMnO 3+δ is shown to be an effective temperature-swing oxygen storage material working at low temperatures (150-300 °C) in pure oxygen if adequately processed or obtained having sub-micrometer primary particles with limited number of big agglomerates. If the DO of the water exceeds the maximum for that temperature, the water is supersaturated and the D. As used in this section: A bulk oxygen system is an assembly of equipment, such as oxygen storage containers, pressure regulators, safety devices, vaporizers, manifolds, and interconnecting piping, which has storage capacity of more than 13,000 cubic feet of oxygen, normal temperature and pressure (NTP), connected in service or ready for service, or more than 25,000 cubic feet. 5,700 o F when burned. There are several excellent answers here, but I'll add one little bit that some may perhaps find useful.
