ACOG Coding staff has developed laparoscopic hysterectomy charts that summarize the differences in these procedures. The information within the charts is intended to be used as a guide for correct coding and should not be used without a current CPT book.
Part of the Computing fundamentals glossary: A gravity wave (or gravitational wave) is a ripple in the curvature of the space-time continuum (the enmeshed combination of our three perceived physical dimensions, plus time) created by the movement of matter.f a gravitational wave were to pass through, the distance between the weights (which is measured by a laser beam moving back and forth between the mirrors and then recombined at a photodetector) would be altered.
To detect something, you need to be affected by it. A gravitational wave stretches space in one direction and contracts it in the other direction. [*] The interferometers measure the distance between the mirrors, so LIGO is looking for a periodic expansion and contraction of the two path lengths (hence being affected).
