- anterior pituitary luteotropin — prolactin.
- arbitrary precision calculator — (tool) An arbitrary precision C-like calculator. Interpreter version 1.26.4 by David I. Bell <[email protected]>. Ported to Linux.
- automatically programmed tools — (language) (APT) A language for numerically controlled machine tools. Versions: APT II (IBM 704, 1958), APT III (IBM 7090, 1961).
- computational adequacy theorem — This states that for any program (a non-function typed term in the typed lambda-calculus with constants) normal order reduction (outermost first) fails to terminate if and only if the standard semantics of the term is bottom. Moreover, if the reduction of program e1 terminates with some head normal form e2 then the standard semantics of e1 and e2 will be equal. This theorem is significant because it relates the operational notion of a reduction sequence and the denotational semantics of the input and output of a reduction sequence.
- computer telephony integration — Computer Telephone Integration
- dichlorodiphenyldichloroethane — (organic chemistry) An organochlorine insecticide that is a metabolite of DDT.
- federal republic of yugoslavia — a former country in SE Europe, comprising Serbia and Montenegro, that was formed in 1991 but not widely internationally recognized until 2000; it was replaced by the Union of Serbia and Montenegro in 2003 (dissolved 2006)

- international geophysical year — the 18-month period from July 1, 1957, to Dec 31, 1958, during which a number of nations agreed to cooperate in a geophysical research programme
- kitt peak national observatory — the U.S. national astronomical observatory near Tucson, Arizona, having over fifteen telescopes, including a 158-inch (4-meter) reflecting telescope.
- laboratory instrument computer — (computer) (LINC) A computer which was originally designed in 1962 by Wesley Clark, Charles Molnar, Severo Ornstein and others at the Lincoln Laboratory Group, to facilitate scientific research. With its digital logic and stored programs, the LINC is accepted by the IEEE Computer Society to be the World's first interactive personal computer. The machine was developed to fulfil a need for better laboratory tools by doctors and medical researchers. It would supplant the 1958 Average Response Computer, and was designed for individual use. Led by William N. Papian and mainly funded by the National Institute of Health, Wesley Clark designed the logic while Charles Molnar did the engineering. The first LINC was finished in March 1962. In January 1963, the project moved to MIT, and then to Washington University (in St. Louis) in 1964. The LINC had a simple operating system, four "knobs" (which was used like a mouse), a Soroban keyboard (for alpha-numeric data entry), two LINCtape drives and a small CRT display. It originally had one kilobit of core memory, but this was expanded to 2 Kb later. The computer was made out of Digital Equipment Corporation (DEC) hardware modules. Over 24 LINC systems had been built before late 1964 when DEC began to sell the LINC commercially. After the introduction of the PDP-8, Dick Clayton at DEC produced a rather frightening hybrid of the LINC and PDP-8 called a LINC-8. This really was not a very satisfactory machine, but it used the new PDP-8 style DEC cards and was cheaper and easier to produce. It still didn't sell that well. In the late 1960s, Clayton brought the design to its pinnacle with the PDP-12, an amazing tour de force of the LINC concept; along with about as seamless a merger as could be done with the PDP-8. This attempted to incorporate TTL logic into the machine. The end of the LINC line had been reached. Due to the success of the LINC-8, Spear, Inc. produced a LINC clone (since the design was in the public domain). The interesting thing about the Spear micro-LINC 300 was that it used MECL II logic. MECL logic was known for its blazing speed (at the time!), but the Spear computer ran at very modest rates. In 1995 the last of the classic LINCs was turned off for the final time after 28 years of service. This LINC had been in use in the Eaton-Peabody Laboratory of Auditory Physiology (EPL) of the Massachusetts Eye and Ear Infirmary. On 15 August 1995, it was transferred to the MIT Computer Museum where it was put on display.
- media gateway control protocol — (communications, protocol) (MGCP) A protocol used within a Voice over IP system. MGCP is an IETF work in progress, it superseded SGCP. MGCP is an internal protocol used within a distributed system that appears to the outside world as a single VoIP gateway. This system is composed of a Call Agent, and a set of gateways, including at least one "media gateway" that performs the conversion of media signals between circuits and packets, and at least one "signalling gateway" when connected to an SS7 controlled network.
- palestinian national authority — the authority formed in 1994 to govern the Palestinian Administered Territories: it controls policy on health, education, social welfare, direct taxation, tourism, and culture and manages elections to the Palestinian Council
- passive-aggressive personality — a personality disorder characterized by aggressive behavior expressed in passive ways, as procrastination, stubbornness, or pouting.
- play (a piece of music) by ear — If you play by ear or play a piece of music by ear, you play music by relying on your memory rather than by reading printed music.
- realtime disk operating system — (operating system) A Data General operating system developed in the 1970s or 1980s. When used in conjuction with a BASIC (e.g. Business Basic) it could support 16 concurrent users at the record locking level and two printers all on 128K memory. Reputedly IBM wanted to license this for the first IBM PC but DG turned them down so they went to Microsoft instead. How different the world could have been.
- the life and soul of the party — If you refer to someone as the life and soul of the party, you mean that they are very lively and entertaining on social occasions, and are good at mixing with people. In American English, you usually say that they are the life of the party.

- unplanned shutdown of refinery — An unplanned shutdown of refinery is when processes in a refinery are stopped unexpectedly, often because something hazardous has happened.
- upright database technology ab — (company) The Swedish company that developed the Mimer SQL database.
