NASA’s SpaceX Crew-1 Astronauts Headed to International Space Station

Leave a Comment

An international crew of astronauts is en route to the International Space Station following a successful launch on the first NASA-certified commercial human spacecraft system in history. NASA’s SpaceX Crew-1 mission lifted off at 7:27 p.m. EST Sunday from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. The SpaceX Falcon 9 rocket […]

Neuronal adenosine A2A receptors signal ergogenic effects of caffeine

Leave a Comment

Abstract Caffeine is one of the most used ergogenic aid for physical exercise and sports. However, its mechanism of action is still controversial. The adenosinergic hypothesis is promising due to the pharmacology of caffeine, a nonselective antagonist of adenosine A1 and A2A receptors. We now investigated A2AR as a possible ergogenic mechanism through pharmacological and genetic inactivation. […]

Frontal and motor cortex oxygenation during maximal exercise in normoxia and hypoxia

Leave a Comment

Abstract Reductions in prefrontal oxygenation near maximal exertion may limit exercise performance by impairing executive functions that influence the decision to stop exercising; however, whether deoxygenation also occurs in motor regions that more directly affect central motor drive is unknown. Multichannel near-infrared spectroscopy was used to compare changes in prefrontal, premotor, and motor cortices during […]

Characterization and modeling of thermo-mechanical fatigue crack growth in a single crystal superalloy

Leave a Comment

Turbine engine blades are subjected to extreme conditions characterized by significant and simultaneous excursions in both stress and temperature. These conditions promote thermo-mechanical fatigue (TMF) crack growth which can significantly reduce component design life beyond that which would be predicted from isothermal/constant load amplitude results. A thorough understanding of the thermo-mechanical fatigue crack behavior in […]
