But non-military items also arrived for activation and test.

The scientist set the controls and turned on the activation switch.

There is no known explanation for this type of activation of the enzyme.

How this activation is being aided and accelerated by another source of dynamic energy: irradiation from the sun.

It is usually measured by inserting materials of known composition and measuring their activation.

Then, as Tony switched the activation circuit, the vertical line formed a pattern that varied in width from top to bottom.

The activation thereafter had to be done in special equipment permitting of fine control of temperature.

Activation meant turning them on and giving them a sort of basic training in the tasks they were designed to do.
