Program Memory Area

PCA, PMA, PA, SUA

PCA: The Power Calibration Area is used to determine the correct power level for the laser.

PMA: The Program Memory Area of a CDRW is a record of the data recorded on an unfinished or unfinalized disc.
It is used as a transition TOC while the session is still open.
PMA records may contain information on up to 99 audio tracks and their start and stop times (CD-DA),
or sector addresses for the start of data files for each session on a data CD.

PA: The Program Area contains the audio tracks or data files.

Each session on a multi-session disc has a corresponding lead-in, PMA, PA and lead-out.

When the session is closed TOC information in the PMA is written into a lead-in area and the PCA and PMA are logically eliminated.
The lead-out is created to mark the end of the data in the session.

SUA: The System User Area The PCA and the PMA grouped together are sometimes denoted as the System User Area.

Federal Food, Drug, and Cosmetic Act

The United States Federal Food, Drug, and Cosmetic Act (abbreviated as FFDCA, FDCA, or FD&C), is a set of laws passed by Congress in 1938 giving authority to the U.S. Food and Drug Administration (FDA) to oversee the safety of food, drugs, and cosmetics. A principal author of this law was Royal S. Copeland, a three-term U.S. Senator from New York. In 1968, the Electronic Product Radiation Control provisions were added to the FD&C. Also in that year the FDA formed the Drug Efficacy Study Implementation (DESI) to incorporate into FD&C regulations the recommendations from a National Academy of Sciences investigation of effectiveness of previously marketed drugs. The act has been amended many times, most recently to add requirements about bioterrorism preparations.

The introduction of this act was influenced by the death of more than 100 patients due to a sulfanilamide medication where diethylene glycol was used to dissolve the drug and make a liquid form. See Elixir Sulfanilamide disaster. It replaced the earlier Pure Food and Drug Act of 1906.

Photo Marketing Association

The Photo Marketing Association International (or PMA) International Convention and Trade Show is an annual imaging technology trade show conducted by PMA held in Las Vegas. Since 2012, the show has been branded as PMA@CES, reflecting its rescheduling to coincide with International CES, a major annual consumer electronics trade show also held in Las Vegas.

The PMA International Convention and Trade Show is frequently the occasion for the public introduction of important imaging products. The major competition for this trade show is Photokina, held in even-numbered years in Cologne, Germany.

In 2012, PMA announced it would launch an online community known as The Big Photo Show, with associated trade shows under that banner in the U.S. The first such show was held in Los Angeles in May 2013, with another scheduled for that city in May 2014. Unlike PMA@CES, which is restricted exclusively to trade visitors, The Big Photo Show is specifically intended for consumers.
