The changing of a passive surface of a metal to a chemically active state Contrast with passivation
The activation Quartz crystal can be recognized by an inclined window located on the side (right or left) of the primary face of the crystal A left activation window increases the performance of left brain functions while a right activation increases, stimulates and enhances the performance of the right brain Using both can bring a melding and synthesis of the left and right brain
Viruses that have damage routines will activate when certain conditions are met, for example, on a certain date or when a particular action is taken by the user Viruses without damage routines don't activate, instead causing damage by stealing storage space (see Discovery)

Sends a very similar command to the card that DIRECTV sends when activating programming, except it activates all the channels that could normally be subscribed to (hence PPV's, etc are not opened) DirecTV combats Activation by constantly sending down "wipe" commands, which clears the extra programming information from cards

The changing of the passive surface of a metal to a chemically active state Contrast with passivation
Is any process by which high surface area is created In the instance of activated charcoal, activation is accomplished by firing in the absence of oxygen, which burns off volatiles, leaving voids and vacuoles In the case of alumina, the activation is formed by driving water from the crystal state to the vapor state
