Oxygen consumption dynamics in steady-state tumour models [PDF]

Royal Society Open Science, 2014
Oxygen levels in cancerous tissue can have a significant effect on treatment response: hypoxic tissue is both more radioresistant and more chemoresistant than well-oxygenated tissue.

Energy Consumption Optimization of a Synthetic Ammonia Process Based on Oxygen Purity

Chemical Engineering Transactions, 2018
The energy consumption of an ammonia process is huge, and it occupies a large proportion in the industrial energy consumption. The air separation unit is an important energy-consuming unit in the process of ammonia synthesis. For the ammonia process with

Substantial oxygen consumption by aerobic nitrite oxidation in oceanic oxygen minimum zones

Nature Communications, 2021
Oxygen is fundamental for marine life, yet it is absent from large areas of the ocean. Here the authors demonstrate that microbial nitrite oxidation effectively consumes oxygen where oxygen concentrations are low, playing a pivotal role in these regions.

Comparison of methods for measuring oxygen consumption rate of Hyriopsis cumingii

浙江大学学报. 农业与生命科学版, 2013
Oxygen consumption rate is an important physiological indicator for evaluating the environmental adaptation of bivalves. Generally, oxygen consumption rate of bivalve is measured with closed respirometry or flow-through respirometry.

Independent measurement of oxygen consumption and oxygen delivery [PDF]

Journal of Surgical Research, 1989
This experiment investigated the relationship between oxygen consumption and oxygen delivery (cardiac output X arterial oxygen content) in an acute canine model. Previous studies investigating this relationship have largely utilized methods in which oxygen consumption and oxygen delivery were each calculated using the same measured variables resulting ...
