The effects of changing climate on faunal depth distributions determine winners and losers

open access: yes, 2014
Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution.

The Effects of Hyperbaric Oxygen Therapy on Blood Glucose Levels and Lipid Profile in Diabetes Mellitus Patients [PDF]

open access: yes, 2020
Diabetes mellitus and its complications are still a major health problem in the world. Diabetes mellitus is closely related to the lipid profile, especially concerning the cardiovascular disease.

Mild hyperbaric oxygen: mechanisms and effects

open access: yesJournal of Physiological Sciences, 2019
Adequate oxygen supply by exposure to mild hyperbaric oxygen at appropriately high atmospheric pressure (1266–1317 hPa) and increased oxygen concentration (35–40% oxygen) has a possibility of improving the oxidative metabolism in cells and tissues ...

Short-term effect of hyperbaric exposure on Ventilation: A Control Study of 12m-depth Single No-decompression Dive Experiment [PDF]

open access: yes, 2017
Objective: To study to what extent or durations of ventilation effect in a single no-decompression dive of 12 meters to a diver. Methods: There are 29 healthy volunteers divers assigned into SCUBA diving of 12m-depth underwater (the Experimental Group, EG)and chamber dive under 2.2 ATA for 20min (the Control Group, CG) matched with the factors of the ...

Computational Discovery of Fast Interstitial Oxygen Conductors [PDF]

open access: yesarXiv, 2023
New highly oxygen-active materials may enhance many energy-related technologies by enabling efficient oxygen-ion transport at lower temperatures, e.g., below 400 Celsius. Interstitial oxygen conductors have the potential to realize such performance but have received far less attention than vacancy-mediated conductors.

Factors controlling oxygen migration barriers in perovskites [PDF]

open access: yesSolid State Ionics 296 (2016) 71-77, 2016
Perovskites with fast oxygen ion conduction can enable technologies like solid oxide fuel cells. One component of fast oxygen ion conduction is low oxygen migration barrier. Here we apply ab initio methods on over 40 perovskites to produce a database of oxygen migration barriers ranging from 0.2 to 1.6 eV. Mining the database revealed that systems with

Oxygen depletion hypothesis remains controversial: a mathematical model of oxygen depletion during FLASH radiation [PDF]

open access: yesRadiation Research . 2022. 197(2):175-183, 2020
Background: Experiments have reported low normal tissue toxicities during FLASH radiation, but the mechanism has not been elaborated. Several hypotheses have been proposed to explain the mechanism. The oxygen depletion hypothesis has been introduced and mostly studied qualitatively.

Hypoxia and hyperbaric oxygen therapy: a review

open access: yesInternational Journal of General Medicine, 2018
Hypoxia causes a cascade of activity from the level of the individual down to the regulation and function of the cell nucleus. Prolonged periods of low oxygen tension are a core feature of several disease states.

Singlet Oxygen Generation as a Major Cause for Parasitic Reactions during Cycling of Aprotic Lithium-Oxygen Batteries [PDF]

open access: yesNature Energy 2, 17036 (2017), 2017
Non-aqueous metal-oxygen batteries depend critically on the reversible formation/decomposition of metal oxides on cycling. Irreversible parasitic reactions cause poor rechargeability, efficiency, and cycle life and have predominantly been ascribed to the reactivity of reduced oxygen species with cell components.

Effect of Oxygen Mole Fraction on Static Properties of Pressure-Sensitive Paint [PDF]

open access: yesSensors, Vol. 21, No. 4, 1062 (2021), 2020
The effects of oxygen mole fraction on the static properties of pressure-sensitive paint (PSP) were investigated. Sample coupon tests using a calibration chamber were conducted for polymer-based PSP (PHFIPM-PSP), polymer/ceramic PSP (PC-PSP), and anodized-aluminium PSP (AA-PSP).
