Chondrite meteorite with calcium–aluminium-rich inclusions seen as white specks. A calcium–aluminium-rich inclusion or Ca–Al-rich inclusion (CAI) is a submillimeter- to centimeter-sized light-colored calcium- and aluminium-rich inclusion found in carbonaceous chondrite meteorites.
Particles of refractory material in contact with aluminium can detach and become inclusions. We can find graphite inclusions (C), alumina inclusions (alpha-Al 2 O 3), CaO, SiO 2, … After some time, graphite refractory in contact with aluminium will react to create aluminum carbides (harder and more detrimental inclusions).
These are known as calcium–aluminium-rich inclusions or "CAIs", so named because they are dominantly composed of calcium- and aluminum-rich silicate and oxide minerals. Like many chondrites, Allende is a breccia , and contains many dark-colored clasts or "dark inclusions" which have a chondritic structure that is distinct from the rest of the ...
The Allende meteorite, which fell in 1969, contained abundant calcium–aluminium-rich inclusions (CAIs). These are very refractory materials and were interpreted as being condensates from a hot solar nebula. [15] [16] then discovered that the oxygen in these objects was enhanced in 16 O by ~5% while the 17 O/ 18 O was the same as terrestrial ...
Krotite was reported in 2011 [3] in a calcium-aluminium-rich inclusion (CAI) in the carbonaceous chondrite meteorite NWA (North West Africa) 1934, which landed in Morocco. [4] The mineral name was approved by the International Mineralogical Association (IMA 2010-038) [ 5 ] and honors Alexander N. Krot, a researcher in cosmochemistry at the ...
Researchers discovered that consuming an additional 300 milligrams (mg) of calcium each day, the equivalent of around 1 glass of milk, was associated with a 17% lowered risk for colorectal cancer.

For instance, if the playoff was today, No. 12 Clemson and No. 13 Alabama would miss the field while No. 16 Arizona State would advance through an auto bid as, presumably, the Big 12 champion.
