Sorry, no etymologies found.
Exposure to ionizing radiation during a medical examination can be limited by lead shielding, tube collimation and using the lowest dose necessary to obtain a diagnostic image.
E.g., the formation and collimation of jets is still quite unknown.
The old one, you may recall, has deteriorated over the years it's close to 30 years old, after all and no longer adjusts for collimation.
The replacement is a nice model from Astrosystems, which features four-point collimation adjustment.
BONNIE RUCKS, DEVRY UNIVERSITY: It is a collimation of all of the students 'learning experiences here at DeVry and their real world experience.
I think Jeff #4 has it right: the ‘illumination’ risk is only evident on takeoff or final approach… and even then, why bother with a laser when a high-collimation halogen light will do the job?
Even with the collimation provided by a parabolic sending station, my gut feeling is that the physics (scattering, signal-to-noise, etc) is very much against it working.
"A magnetic pulse of very high power seriously interfered with plasma collimation before the shutoff could respond," stated the computer.
It consists of spider webs set within a graduated metallic circle, the webs movable by screws, and the whole instrument capable of rotating about the collimation axis of the telescope.
This post was sawed off squarely on top so that the line of collimation of an engineer's transit set on it without
