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. The four CAIs that have been dated using the Pb-Pb chronometer yield a weighted mean age of 4567.30 ± 0.16 Myr.
"You Can Call Me Al" is a song by American singer-songwriter Paul Simon. It was the lead single from his seventh studio album, Graceland (1986), released on Warner Bros. Records . Written by Simon, its lyrics follow an individual seemingly experiencing a midlife crisis .
A cardboard sign calling for inclusive language at a feminist protest in Madrid, 2013, with basic usage instructions. Inclusive language is a language style that seeks to avoid expressions that its proponents perceive as expressing or implying ideas that are sexist, racist, or otherwise biased, prejudiced, or insulting to particular group(s) of people; and instead uses language intended by its ...
Social inclusion is to some extent the positive policies that combat social exclusion. However, it is not merely a mirror image of exclusion. Subcategories.
Al-Ca composite is a high-conductivity, high-strength, lightweight composite consisting of sub-micron-diameter pure calcium metal filaments embedded inside a pure aluminium metal matrix. The material is still in the development phase, but it has potential use as an overhead high-voltage power transmission conductor . [ 1 ]
Unit cell of Ca 2 SiO 4. Color code: red (O), blue (Ca), gold (Si). As verified by X-ray crystallography, calcium silicate is a dense solid consisting of tetrahedral orthosilicate (SiO 4 4-) units linked to Ca 2+ via Si-O-Ca bridges. There are two calcium sites. One is seven coordinate and the other is eight coordinate. [11]

The main constituent, and also the most reactive phase, of calcium aluminate cements is the monocalcium aluminate (CaAl 2 O 4 = CaO · Al 2 O 3, also written as CA in the cement chemist notation). It usually contains other calcium aluminates as well as a number of less reactive phases deriving from impurities in the raw materials.
