Optical disc authoring

Optical disc authoring, including DVD and Blu-ray Disc authoring is the process of assembling source material—video, audio or other data—into the proper logical volume format to then be recorded ("burned") onto an optical disc (typically a compact disc or DVD).

Process

To burn an optical disc, one usually first creates an optical disc image with a full file system, of a type designed for the optical disc, in temporary storage such as a file in another file system on a disk drive. Then, one copies the image to the disc.

Most optical disc authoring utilities create a disc image and copy it to the disc in one bundled operation, so that end-users often do not know the distinction between creating and burning. However, it is useful to know because creating the disc image is a time-consuming process, while copying the image is much faster. Most disc burning applications silently delete the image from the Temporary folder after making one copy. If users override this default, telling the application to preserve the image, they can reuse the image to create more copies. Otherwise, they must rebuild the image each time they want a copy.

Troponin C

Troponin C is a part of the troponin complex. It contains four calcium-binding EF hands, although different isoforms may have fewer than four functional calcium-binding subdomains. It is a component of thin filaments (along with actin and tropomyosin). It contains an N lobe and a C lobe. The C lobe serves a structural purpose and binds to the N domain of troponin I (TnI). The C lobe can bind either Ca²⁺ or Mg²⁺. The N lobe, which binds only Ca²⁺, is the regulatory lobe and binds to the C domain of troponin I after calcium binding.

The tissue specific subtypes are:

Tournament of Champions (debate)

The Tournament of Champions (TOC) is a national high school debate tournament held at the University of Kentucky every year on the last weekend in April. The Tournament is considered the national championship of the “National Circuit,” with debaters having to apply to compete. It is considered the most prestigious and competitive American high school debate tournament. The tournament uses a bid system, in which placing high enough in certain, nationally or regionally respected tournaments earns debaters a bid, with at least 2 bids needed to compete. In addition to this, competitors can automatically qualify by placing high enough at last year’s tournament (or one of the two other national tournaments) or by getting accepted as an at large entry.

The tournament was created by Dr. J.W. Patterson, the former director of debate at the University of Kentucky. Incepted in 1972, it serves as the pinnacle of high school debate, allowing the best debaters in the United States to compete without other, less experienced debaters affecting the rankings. The Tournament currently holds competition in policy debate, Lincoln–Douglas debate, public forum debate, and Congressional Debate.
