Well-posedness and singularity formation for inviscid Keller-Segel-fluid system of consumption type [PDF]
, 2021 We consider the Keller-Segel system of consumption type coupled with an incompressible fluid equation. The system describes the dynamics of oxygen and bacteria densities evolving within a fluid. We establish local well-posedness of the system in Sobolev spaces for partially inviscid and fully inviscid cases. In the latter, additional assumptions on the

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.

Maximal oxygen consumption and oxygen uptake efficiency in adolescent males
Journal of Exercise Science & Fitness, 2021 Background/objective: Measures of oxygen uptake efficiency (OUE) have been used to evaluate cardiorespiratory fitness (CRF) in adolescents unable to perform maximal exercise. The oxygen uptake efficiency slope (OUES) and oxygen uptake efficiency plateau (

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

SGLT2 inhibition reduces myocardial oxygen consumption
Metabolism Open, 2022 Aims/hypothesis: SGLT2 inhibition is associated with a reduced risk of cardiac disease that is still largely unexplained. According to one hypothesis, improved myocardial energetics may explain the cardioprotective effects of SGLT2i.

Pattern wavelengths and transport characteristics in three-dimensional bioconvection generated by chemotactic bacteria [PDF]
, 2022 We conducted a three-dimensional numerical simulation of bioconvection generated by oxygen-reactive chemotactic bacteria. This study investigated the bioconvection patterns, interference between plumes, and the wavelength of bioconvection patterns.
