The Gall-Peters Projection world map. While originally created by James Gall in 1885, the Gall-Peters Projection came into public consciousness in 1967 when Arno Peters championed it as a more accurate representation of the size of countries. It was considered controversial for calling into question the way the âthird-worldâ is represented.
APC stands for Medicare's ambulatory payment classification. Hospitals use Medicare APC codes to bill the federal government for hospital services given to Medicare and Medicaid patients. Every item, machine or procedure used to care for a Medicare or Medicaid patient has a specialized code that is submitted by the hospital during the billing process.
Asynchronous Procedure Calls. An asynchronous procedure call (APC) is a function that executes asynchronously in the context of a particular thread. When an APC is queued to a thread, the system issues a software interrupt. The next time the thread is scheduled, it will run the APC function.n APC generated by the system is called a kernel-mode APC. An APC generated by an application is called a user-mode APC. A thread must be in an alertable state to run a user-mode APC. Each thread has its own APC queue.
