During the mid-80s, RCA released the Colortrak 2000, a television identical to the Dimensia table-top model. Even though the Colortrak was considered the mid-range model, those bearing the name Co... |
https://en.wikipedia.org/wiki/Kasha%27s%20rule | Kasha's rule is a principle in the photochemistry of electronically excited molecules. The rule states that photon emission (fluorescence or phosphorescence) occurs in appreciable yield only from the lowest excited state of a given multiplicity. It is named after American spectroscopist Michael Kasha, who proposed it i... |
https://en.wikipedia.org/wiki/Anterior%20external%20arcuate%20fibers | The anterior external arcuate fibers (ventral external arcuate fibers) vary as to their prominence: in some cases they form an almost continuous layer covering the medullary pyramids and olivary body, while in other cases they are barely visible on the surface.
Most of them reach the surface by way of the anterior med... |
https://en.wikipedia.org/wiki/Exception%20safety | Exception safety is the state of code working correctly when exceptions are thrown. To aid in ensuring exception safety, C++ standard library developers have devised a set of exception safety levels, contractual guarantees of the behavior of a data structure's operations with regards to exceptions. Library implementers... |
https://en.wikipedia.org/wiki/Ergun%20equation | The Ergun equation, derived by the Turkish chemical engineer Sabri Ergun in 1952, expresses the friction factor in a packed column as a function of the modified Reynolds number.

https://en.wikipedia.org/wiki/Potentially%20Hazardous%20Food | Potentially Hazardous Food is a term used by food safety organizations to classify foods that require time-temperature control to keep them safe for human consumption. A PHF is a food that:
Contains moisture – usually regarded as a water activity greater than 0.85
Contains protein
Is neutral to slightly acidic – typ... |
https://en.wikipedia.org/wiki/Thyroxine%205-deiodinase | Thyroxine 5-deiodinase also known as type III iodothyronine deiodinase (EC number 1.21.99.3) is an enzyme that in humans is encoded by the DIO3 gene. This enzyme catalyses the following chemical reaction
3,3',5'-triiodo-L-thyronine + iodide + A + H+ L-thyroxine + AH2
The protein encoded by this intronless gene belo... |
https://en.wikipedia.org/wiki/Rovibronic%20coupling | Rovibronic coupling, also known as rotation/vibration-electron coupling, denotes the simultaneous interactions between rotational, vibrational, and electronic degrees of freedom in a molecule. When a rovibronic transition occurs, the rotational, vibrational, and electronic states change simultaneously, unlike in rovibr... |
https://en.wikipedia.org/wiki/Test%20CD | A test CD is a compact disc containing tracks of musical and technical tests and demonstrations. Most of the tracks are made of electronic signals and pure frequencies. The purpose of these specialized compact discs is to make accurate tests and calibrate audio equipment.

https://en.wikipedia.org/wiki/Efficient%20coding%20hypothesis | The efficient coding hypothesis was proposed by Horace Barlow in 1961 as a theoretical model of sensory coding in the brain. Within the brain, neurons communicate with one another by sending electrical impulses referred to as action potentials or spikes. One goal of sensory neuroscience is to decipher the meaning of ... |
https://en.wikipedia.org/wiki/Pi%20helix | A pi helix (or π-helix) is a type of secondary structure found in proteins. Discovered by crystallographer Barbara Low in 1952 and once thought to be rare, short π-helices are found in 15% of known protein structures and are believed to be an evolutionary adaptation derived by the insertion of a single amino acid into... |
https://en.wikipedia.org/wiki/Ruth%20Teitelbaum | Ruth Teitelbaum ( Lichterman; February 1, 1924 – August 9, 1986) was one of the first computer programmers in the world. Teitelbaum was one of the original programmers for the ENIAC computer.
The other five ENIAC programmers were Jean Bartik, Betty Holberton, Kathleen Antonelli, Marlyn Meltzer, and Frances Spence.

https://en.wikipedia.org/wiki/310%20helix | {{DISPLAYTITLE:310 helix}}
A 310 helix is a type of secondary structure found in proteins and polypeptides. Of the numerous protein secondary structures present, the 310-helix is the fourth most common type observed; following α-helices, β-sheets and reverse turns. 310-helices constitute nearly 10–15% of all helices i... |
