1.   It is easier to observe and measure electrical activity than it is to understand the chemical properties.

2.   The study of the kinetics of this reaction enables the laboratory to measure enzyme activity accurately and specifically.

3.   Bosses could measure brain activity to learn worker quality.

4.   In addition, to determine the dietary effects on the cytolytic potency of the intestinal contents, luminal lytic activity was measured as lysis of erythrocytes by faecal water.

5.   PAF activity was measured by platelet aggregation using a Chrono-log Corporation aggregometer.

6.   Whereas biochemical studies can measure enzyme activities, immunohistochemistry can only provide information on enzyme protein, some of which may be inactive.

7.   This finding is supported by the results of Howie et al, who used a radioimmunoassay to measure the activity of glutathione S-transferase expression.

8.   A traditional method of measuring PR activity is in terms of column centimetres gained from press coverage.

9.   Goskomstat admits that it is not organized to record the activity of the private sector and has begun to examine ways of measuring this activity more accurately.

10.   In the study, volunteers are isolated in separate rooms and hooked up with electrodes to a machine that measures brain activity.
