Acute Hypoxia Decreases Maximum Fat Oxidation Rate During Step Incremental Exercise Normalized to Respiratory Compensation Point

European Journal of Sport Science, Volume 26, Issue 2, February 2026.
ABSTRACT Whether fat oxidation (FATox) is altered during exercise in hypoxia remains equivocal due to differences in experimental protocols. Furthermore, to date no investigation has reported the effect of hypoxia on maximal fat oxidation rate (MFO).

Lifetime Analysis of IGBT Power Modules in Passively Cooled Tidal Turbine Converters

Energies, 2020
Thermal cycling is one of the major reasons for failure in power electronic converters. For submerged tidal turbine converters investigating this failure mode is critical in improving the reliability, and minimizing the cost of energy from tidal turbines.
