Cerebral oxygenation and skeletal muscle responses to time trial, maximal oxygen uptake and time to exhaustion exercise

Experimental Physiology, EarlyView.
Abstract This study investigated cerebral and neuromuscular responses to three exercise models: time trial (TT), maximal oxygen uptake (V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$) and time to exhaustion (TTE). Fourteen participants completed the tests in the following order: V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$, TT and ...

Investigating & Improving the Drooping Curve of A Two-Stage Feed Pump [PDF]

, 2018
TutorialsA two-stage between-bearing pump of the upgraded material was supplied to replace the existing machine. The pump utilized a higher number of impeller blades to obtain higher efficiency at its design point, but exhibited a drooping head-flow ...

Sprint‐interval training with post‐exercise blood flow restriction increases mitochondrial content and respiration

The Journal of Physiology, EarlyView.
Abstract figure legend The mechanisms underpinning improved maximal oxygen uptake following sprint interval training (SIT) with post‐exercise blood flow restriction (BFR), compared to SIT alone, remain unclear. This study examined the effects of 6 week SIT with (BFR; n = 12) or without (CON; n = 8) post‐exercise BFR on V̇O2peak${{\dot{V}}_{{{{\mathrm{O}

Pump turbines in existing powerplants

, 2019
En brukervennlig metode for å designe kontraroterende aksialpumper har blitt utviklet ved bruk av Matlab. Grafiske brukergrensesnitt har blitt laget for å skrive inn designparametre og å vise designresultater. Designmetoden benytter seg av eksisterende løftelinjeteori for design og optimalisering av kontraroterende propeller, men den er modifisert for ...

Key Drivers for Offshore Wind Deployment in the Western United States

Wind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT The western coast of the United States has abundant natural resources, including wind, sun, and water. Despite strong ocean winds, offshore wind energy (OSW) in the Western United States is in the early stages of technology development due largely to the deep water off the coast, which requires floating platforms rather than fixed‐bottom ...

Improved Suter Transform for Pump-Turbine Characteristics

International Journal of Fluid Machinery and Systems, 2010
Standard dimensionless parameters cannot simultaneously represent all operation modes of a pump-turbine. They either have singularities at E=0 and multiple values in the ‘unstable’ areas, or else get singular at n=0. P. Suter (1966) introduced an alternative set of variables which avoids singularity and always remains unique-valued.
