Aes grave. Aes grave ("heavy bronze") is a term in numismatics indicating bronze cast coins used in central Italy during the 3rd century BC, whose value was generally indicated by signs: I for the as, S for semis and pellets for unciae. Standard weights for the as were 272, 327, or 341 grams, depending upon the issuing authority.
It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. [1] The plasma is a high temperature source of ionised source gas (often argon). The plasma is sustained and maintained by inductive coupling ...
Generation Z (often shortened to Gen Z ), colloquially known as Zoomers, [1] [2] [3] is the demographic cohort succeeding Millennials and preceding Generation Alpha. Researchers and popular media use the mid-to-late 1990s as starting birth years and the early 2010s as ending birth years.
An AES3 signal can carry two channels of pulse-code-modulated digital audio over several transmission media including balanced lines, unbalanced lines, and optical fiber. [1] AES3 was jointly developed by the Audio Engineering Society (AES) and the European Broadcasting Union (EBU) and so is also known as AES/EBU.
Z-Library (abbreviated as z-lib, formerly BookFinder) is a shadow library project for file-sharing access to scholarly journal articles, academic texts and general-interest books. It began as a mirror of Library Genesis, but has since expanded dramatically. [6] [7]
In chemistry, the letter Z is used to denote the Atomic number of an element (number of protons), such as Z =3 for Lithium. In electrical engineering, Z is used to denote electrical impedance. In astronomy, z is a dimensionless quantity representing redshift. In nuclear physics, Z denotes the atomic number and. Z0.
Aes rude (Latin; lit. ' rough bronze ' ) was a nugget of bronze used as a sort of proto- currency in ancient Italy prior to the use of minted coins made from precious metals. The Italian economy of the time (late middle first millennium BC) was based on a bronze standard (unlike the silver standards in use in contemporary Greece , the Aeginetan ...
Auger electron spectroscopy ( AES; pronounced [oʒe] in French) is a common analytical technique used specifically in the study of surfaces and, more generally, in the area of materials science. It is a form of electron spectroscopy that relies on the Auger effect, based on the analysis of energetic electrons emitted from an excited atom after ...
