Oxygen consumption of animals under conditions of hypokinesia [PDF]

open access: yes
The influence of hypokinesia on the oxygen consumption of rats, dog, and squirrels was investigated. Three periods of gaseous exchange were revealed in rats under conditions of a limited motor activity.

Nanoparticle‐Coated X2CrNiMo17‐12‐2 Powder for Additive Manufacturing—Part II: Processability by Powder Bed Fusion of Metals Using a Laser Beam

open access: yesAdvanced Engineering Materials, EarlyView.
In this manuscript, the processability of X2CrNiMo17‐12‐2 powder coated with silicon carbide, silicon, and silicon nitride nanoparticles is investigated. The amount of nanoparticles varies from 0.25 to 1 vol%. By coating the powder feedstock material with nanoparticles, an enlargement of the process window and an increase in the build rate are achieved.

Influence of inert gases of argon and kripton on oxygen absorption

open access: yesRUDN Journal of Medicine, 2010
Consumption of oxygen by an organism of a rat at long maximum stay in the closed space decreases twice in oxygen-nitric (20-80%) environment. In oxygen-argon (20-80%) environment oxygen consumption decreases in 3 times, and in oxygen-kripton (20-80 ...

Rethinking the Paleoproterozoic Great Oxidation Event: A Biological Perspective [PDF]

open access: yesarXiv, 2012
Competing geophysical/geochemical hypotheses for how Earth's surface became oxygenated - organic carbon burial, hydrogen escape to space, and changes in the redox state of volcanic gases - are examined and a more biologically-based hypothesis is offered in response.
