Oxygen enrichment protects against intestinal damage and gut microbiota disturbance in rats exposed to acute high-altitude hypoxia [PDF]
Frontiers in Microbiology, 2023 Acute high-altitude hypoxia can lead to intestinal damage and changes in gut microbiota. Sustained and reliable oxygen enrichment can resist hypoxic damage at high altitude to a certain extent.

Modified coke breeze distribution in iron ore sintering - a novel technique of reducing energy consumption and improving quality [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2021 In normal sintering of iron ore, there is a wide difference in temperature of the sinter bed between top and bottom; i.e. the flame front temperature of the sinter bed gradually increases towards the bottom because the lower part gets longer time for ...
