The earliest disc records (18891894) were made of various materials including hard rubber. Around 1895, a shellac-based compound was introduced and became standard. Exact formulas for this compound varied by manufacturer and over the course of time, but it was typically composed of about one-third shellac and about two-thirds mineral filler, which meant finely pulverized rock, usually slate and limestone, with an admixture of cotton fibers to add tensile strength, carbon black for color (without this, it tended to be a "dirty" gray or brown color that most record companies considered unattractive), and a very small amount of a lubricant to facilitate mold release during manufacture. Some makers, notably Columbia Records, used a laminated construction with a core disc of coarser material or fiber. The production of shellac records continued until the end of the 78 rpm format (i.e., the late 1950s in most developed countries, but well into the 1960s in some other places), but increasingly less abrasive formulations were used during its declining years and very late examples in truly like-new condition can have as low noise levels as vinyl.
What company was known for laminate construction of discs?
A: Columbia Records

After some time (typically 12 hours in humans, 46 hours in dogs, 34 hours in house cats),[citation needed] the resulting thick liquid is called chyme. When the pyloric sphincter valve opens, chyme enters the duodenum where it mixes with digestive enzymes from the pancreas and bile juice from the liver and then passes through the small intestine, in which digestion continues. When the chyme is fully digested, it is absorbed into the blood. 95% of absorption of nutrients occurs in the small intestine. Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic about 5.6 ~ 6.9. Some vitamins, such as biotin and vitamin K (K2MK7) produced by bacteria in the colon are also absorbed into the blood in the colon. Waste material is eliminated from the rectum during defecation.
Where is chyme absorbed into?
A: blood

Transferring GameCube development to the Wii was relatively simple, since the Wii was being created to be compatible with the GameCube.[o] At E3 2005, Nintendo released a small number of Nintendo DS game cards containing a preview trailer for Twilight Princess. They also announced that Zelda would appear on the Wii (then codenamed "Revolution"), but it was not clear to the media if this meant Twilight Princess or a different game.
Where did Nintendo provide a limited number of Wii previews?
A:
