A magnetohydrodynamic generator ( MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity. An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current. The MHD generator uses hot conductive ionized gas (a ...
Roblox ( / ˈroʊblɒks / ROH-bloks) is an online game platform and game creation system developed by Roblox Corporation that allows users to program and play games created by themselves or other users. Created by David Baszucki and Erik Cassel in 2004 and released in 2006, the platform hosts user-created games of multiple genres coded in the programming language Lua. For most of Roblox ' s ...

Rayon, also called viscose [1] and commercialised in some countries as sabra silk or cactus silk, [2] is a semi-synthetic fiber, [3] made from natural sources of regenerated cellulose, such as wood and related agricultural products. [4] It has the same molecular structure as cellulose.
A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope 99m Tc of technetium from a decaying sample of molybdenum-99. 99 Mo has a half-life of 66 hours [1] and can be easily transported over long distances to hospitals where its decay product technetium-99m (with a half-life of only 6 hours, inconvenient for transport) is ...
Function generator. A simple analog function generator, circa 1990. A DDS function generator. Sine, square, triangle, and sawtooth waveforms. In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies.
Generator matrix. In coding theory, a generator matrix is a matrix whose rows form a basis for a linear code. The codewords are all of the linear combinations of the rows of this matrix, that is, the linear code is the row space of its generator matrix.
Mark Elliot Zuckerberg ( / ˈzʌkərbɜːrɡ /; born May 14, 1984) is an American businessman. He co-founded the social media service Facebook, along with his Harvard roommates in 2004, and its parent company Meta Platforms (formerly Facebook, Inc.), of which he is chairman, chief executive officer and controlling shareholder.
Actinopterygii ( / ˌæktɪnɒptəˈrɪdʒiaɪ /; from actino- 'having rays', and Ancient Greek πτέρυξ (ptérux) 'wing, fins'), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish [2] that comprise over 50% of living vertebrate species. [3] They are so called because of their lightly built fins made of webbings of skin supported by radially extended ...
Rainbow. A colorful rainbow and ring-billed gull. A rainbow is an optical phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the sky. [1] The rainbow takes the form of a multicoloured circular arc. [2]
