What I talk about when I talk about patient self-inflicted lung injury: an ultrastructural perspective [PDF]

Intensive Care Medicine Experimental
Background In preclinical studies, under-assisted respiratory effort has been identified as promoting lung injury, leading to the concept of “patient self-inflicted lung injury” (P-SILI).

Synergistic Effects of Subsurface Drainage and Root-Zone Oxygenation on Wheat Yield and Ion Homeostasis in Saline Soils with Shallow Groundwater [PDF]

Plants
Shallow groundwater in saline soils creates a self-reinforcing cycle where waterlogging-induced root hypoxia impairs the ATP-dependent sodium exclusion mechanisms that plants rely on for salt tolerance.

Storage of grains and technical plants through active ventilation for the purpose of maintaining the quality of stored products [PDF]

E3S Web of Conferences, 2021
The problem of grain storage and storage can be approached from two perspectives: storage and storage of cereals and technical plants within individual agricultural holdings; storage and storage of cereals and technical plants within agricultural ...

CPAP and high-flow nasal oxygen also reduce lung, diaphragm, and accessory muscle injury in experimental self-inflicted lung injury [PDF]

Scientific Reports
Strenuous respiratory effort has been proposed as a second hit, introducing the concepts of “patient self-inflicted lung injury” (P-SILI) and underassistance myotrauma.

The Effect of the Aeration Condition on the Liquid–Solid Material Mixing in a Stirred Tank with a Single-Layer Impeller

Applied Sciences, 2023
In order to increase industrial production quality and efficiency, it is essential to understand how the aeration and no-aeration condition affects liquid and solid material mixing in the stirred tank.

Influence of Self-Compaction on the Airflow Resistance of Aerated Wheat Bulks (Triticum aestivum L., cv. ‘Pionier’)

Applied Sciences, 2022
Aeration is a key post-harvest grain processing operation that forces air through the pore volume of the grain bulk to establish favorable conditions to maintain grain quality and improve its storability.

Effect of Rotational Speed of a Self-Aspirating Mixer on Oxygen Saturation in Water

Polish Maritime Research, 2020
There are two categories of gas-liquid mixers: conventional and special-purpose. In theory, any conventional mixer can be applied to aerate a liquid, but fast-rotating devices are generally preferred.

Analysis of air-water structure in self-aerated developing region of open channel flows

Shui kexue jinzhan, 2014
To investigate the air-water structural characteristic of the self-aerated developing zone in the open channel flow,the bubble size and quantity changes with the self-aeration development were evaluated experimentally,using a double-tip conductivity ...

Self‐Aerated Flows on Chutes and Spillways [PDF]

Journal of Hydraulic Engineering, 1993
In open channel flows an important design parameter is the amount of entrained air. The presence of air within the flow increases the bulk of the flow but also increases the transfer of atmospheric gases (e.g. oxygenation of river). Further aeration of high-velocity flows may prevent or reduce cavitation damage. This paper describes a general method to

Re-Aeration on Stepped Spillways with Special Consideration of Entrained and Entrapped Air

Geosciences, 2018
As with most high-velocity free-surface flows, stepped spillway flows become self-aerated when the drop height exceeds a critical value. Due to the step-induced macro-roughness, the flow field becomes more turbulent than on a similar smooth-invert chute.
