During World War II, the Navy Yard throbbed with activity, employing more than 60,000 workers, but by the mid-1960's the work force had slid below 10,000.
In Denton hatting grew from a cottage industry in the 17th century into a major economic activity employing nearly half the town's population by the 1920s.
The laccase activity employed was 0.5 U/ml.
The low quantities of activity employed for α-therapy using these radionuclides, remain, however, challenging for nuclear imaging using SPECT.
Bibliometric studies rely on the measurement of scientific activity employing statistical procedures (Broadus, 1987) to quantify, classify and organize the extant research in a field (White & McCain, 1998).
Fermentation yielded mean values of total enzyme concentration of 0.44 mg/mL, enzymatic activity (employing lactose as a substrate) of 74 U/mL and specific activity of 168 U/mg.
The autoregression part of the model is the prediction of current ILI activity employing ILI activity from past weeks, and the exogenous inputs come from the tweets from the previous weeks.
With Burkholderia cepacia lipase there is a direct correlation between the power output and the enhancement in catalytic activity; employing higher power (i.e. 110W) resulted in maximum enhancement (Figure 4a).
The resulting Ala96Leu mutant showed a drastic reduction in oxidase activity using molecular oxygen as the electron acceptor and a small increase in dehydrogenase activity employing an artificial electron acceptor.
