https://en.wikipedia.org/wiki/Scram%20%28video%20game%29 | Scram: A Nuclear Power Plant Simulation is an Atari 8-bit family game written by Chris Crawford and published by Atari, Inc. in 1981. Written in Atari BASIC, Scram uses differential equations to simulate nuclear reactor behavior. The player controls the valves and switches of the reactor directly with the joystick.

https://en.wikipedia.org/wiki/Eozoon%20canadense | Eozoön canadense (literally, "dawn animal of Canada") is a pseudofossil.
John William Dawson described the banded structures of coarsely crystalline calcite and serpentine as a gigantic Foraminifera, making it the oldest known fossil . It was found in Precambrian metamorphosed limestone of Canada, at Côte St. Pierre n... |
https://en.wikipedia.org/wiki/Merozygote | Merozygote is a state when a cell, usually bacterial, is temporarily partial diploid as result of DNA transfer processes like conjugation.
One example of how merozygotes can be formed is the transfer of genetic material
of an Hfr cell to an F- cell through conjugation. When an Hfr cell mates with an F- cell, the chrom... |
https://en.wikipedia.org/wiki/Andrews%20%28surname%29 | Andrews is a patronymic surname of English, Scottish, and Norse origin. At the time of the 1881 British Census, its relative frequency was highest in Dorset (3.6 times the British average), followed by Wiltshire, Huntingdonshire, Worcestershire, Hampshire, Suffolk, Cambridgeshire, Devon and Somerset.

https://en.wikipedia.org/wiki/Easton%27s%20theorem | In set theory, Easton's theorem is a result on the possible cardinal numbers of powersets. (extending a result of Robert M. Solovay) showed via forcing that the only constraints on permissible values for 2κ when κ is a regular cardinal are
(where cf(α) is the cofinality of α) and

https://en.wikipedia.org/wiki/RC%20algorithm | The RC algorithms are a set of symmetric-key encryption algorithms invented by Ron Rivest. The "RC" may stand for either Rivest's cipher or, more informally, Ron's code. Despite the similarity in their names, the algorithms are for the most part unrelated. There have been six RC algorithms so far:
RC1 was never publis... |
https://en.wikipedia.org/wiki/Bird%E2%80%93Meertens%20formalism | The Bird–Meertens formalism (BMF) is a calculus for deriving programs from program specifications (in a functional programming setting) by a process of equational reasoning. It was devised by Richard Bird and Lambert Meertens as part of their work within IFIP Working Group 2.1.
It is sometimes referred to in publicati... |
https://en.wikipedia.org/wiki/Low-energy%20electron%20diffraction | Low-energy electron diffraction (LEED) is a technique for the determination of the surface structure of single-crystalline materials by bombardment with a collimated beam of low-energy electrons (30–200 eV) and observation of diffracted electrons as spots on a fluorescent screen.
LEED may be used in one of two ways:

https://en.wikipedia.org/wiki/Theorem%20Proving%20System | The Theorem Proving System (TPS) is an automated theorem proving system for first-order and higher-order logic. TPS has been developed at Carnegie Mellon University. An educational version of it is known as ETPS (Educational Theorem Proving System).

https://en.wikipedia.org/wiki/Sequential%20estimation | In statistics, sequential estimation refers to estimation methods in sequential analysis where the sample size is not fixed in advance. Instead, data is evaluated as it is collected, and further sampling is stopped in accordance with a predefined stopping rule as soon as significant results are observed.

https://en.wikipedia.org/wiki/Direct-ethanol%20fuel%20cell | Direct-ethanol fuel cells or DEFCs are a category of fuel cell in which ethanol is fed directly into the cell. They have been used as a model to investigate a range of fuel cell concepts including the use of PEM.
Advantages
DEFC uses Ethanol in the fuel cell instead of the more toxic methanol. Ethanol is an attractive... |
https://en.wikipedia.org/wiki/Oncostatin%20M | Oncostatin M, also known as OSM, is a protein that in humans is encoded by the OSM gene.
OSM is a pleiotropic cytokine that belongs to the interleukin 6 group of cytokines. Of these cytokines it most closely resembles leukemia inhibitory factor (LIF) in both structure and function. As yet poorly defined, it is proving... |
