Mitochondrial physiology in cardiac muscle of deer mice native to high altitude
The Journal of Physiology, EarlyView.Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Rate oscillations during partial oxidation of methane over chromel–alumel thermocouples
, 2001 A chromel–alumel thermocouple has been found to catalyse the methane/oxygen reaction, the main products being CO, H2 with some CO2 and H2O. Regular oscillations in both reactants, products and temperature have been observed at temperatures around ...

Upscaling methane emissions from rice paddies: problems and possibilities. [PDF]
, 2002 Global methane emission estimates depend highly on the models, techniques, and databases used. Since emissions cannot be measured directly at large scales, it is impossible to judge which estimate is more realistic.

HYDROGEN AS ENERGY CARRIER: DECENTRALIZED PRODUCTION BY AUTOTHERMAL REFORMING OF METHANE [PDF]
, 2008 The aim of this PhD thesis will be the mathematical modeling of an autothermal reactor for hydrogen production from methane, followed by an experimental campaign. Commercial pellets catalysts will be employed, in particular Ni-based and Rh-based catalyst,

Remediation Journal, Volume 36, Issue 2, Spring 2026.ABSTRACT In situ chemical oxidation (ISCO), a remediation technology for soil and groundwater contamination, utilizes oxidants that can impact the soil environment and indirectly influence soil CO2 emissions. Understanding these emissions may support more sustainable ISCO applications by enabling adjustments to treatment conditions that limit ...

Metabolism of methane and propane and the role of the glyoxylate bypass enzymes in Methylocella silvestris BL2 [PDF]
Methylocella silvestris BL2 is a moderately acidophilic facultative methanotroph isolated from forest soil in 2003. Uniquely, it has the ability to grow on a wide range of multi-carbon compounds in addition to methane. An analysis of growth conditions

Frontiers in Marine ScienceA giant Arctic subsea permafrost reservoir of methane (CH4) in different forms (hydrates, free gas) is leaking, likely at an increasing rate under climate warming. This is causing a massive CH4 release from sediments into the water column and atmosphere.
