Crimson Trace is an American manufacturer of laser sight equipment, chiefly but not exclusively for pistols. The firm specializes in in-line upper-grip-mounted red and green laser units, trigger-guard mounted sights, and training units. Crimson Trace partners with manufacturers of firearms in product releases, with many models shipping with ...
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Atom Trap Trace Analysis (ATTA) is an extremely sensitive trace analysis method developed by Argonne National Lab (ANL). ATTA is used on long-lived, stable radioisotopes such as 81 Kr , 85 Kr , and 39 Ar .
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
The Trace Erasure Principle is a stipulation proposed by Noam Chomsky as part of the Generative-Transformational Grammar. Under the Trace Erasure Principle, traces of a noun phrase (NP) can be replaced only by a designated morpheme and not by an arbitrary NP. The following is an example of this Principle: A person is here, waiting for you.
This effect is theorized not to be isolated only to laser tattoo removal, but may also occur with solar radiation. [68] Laser removal of traumatic tattoos may be dangerous depending on the substance of the material embedded in the skin. In one reported instance, the use of a laser resulted in the ignition of embedded particles of firework ...
In a recent study, it took 4 hours to for the air stripper to reach an equilibrium of efficiency in removing NH3-N elements, topping off at an 81.9% removal rate. Comparatively, only 30.7% of NH3-N elements were removed at 10 minutes, suggesting that removal of contaminants of water correlates with the amount of time spent air stripping.
As one example, if there is free space between the two planes, the ray transfer matrix is given by: = [], where d is the separation distance (measured along the optical axis) between the two reference planes.
