This is called the galvanostatic method for measuring the rate of an electrochemical reaction.
Mr. Landau hovered eagerly over a device, attached to the fan, that was measuring the rate of air movement.
By measuring the rate of fall of the oil drops, he was able to determine their weight.
"Measuring the rate at which new species evolve is difficult, but there's no question that the current extinction rates are faster than that; I think it's inevitable," said Stuart.
By carefully measuring the rate at which proteasomes laboured, she found a clear correlation: as the clumps of prions in the sample got bigger, the proteasomes slowed down.
"Well, the thought was that P.S.A. velocity could help you think this through" — that measuring the rate of change would be decisive.
One test for diabetes involves measuring the rate of removal of sugar from the blood, that is, the glucose-tolerance test.
Catalase (CAT) activity was estimated by measuring the rate of decomposition of H2O2 [16].
