(physics, astronomy) the relatively slow nucleosynthesis process, in giant stars, in which neutron capture synthesises elements up to atomic mass number 210 (at which point alpha decay becomes a deterrent to further building).

(physics, astronomy) The relatively rapid nucleosynthesis process, in supernovae, in which a large neutron flux allows rapid neutron capture and synthesis of elements up to the transuranic elements.

(mathematics, probability theory) A function that maps elements of an index set to elements of a collection of random variables; historically, a collection of random variables indexed by a set of numbers usually regarded as points in time.

(physics, astronomy) any nucleosynthesis process, details of which are unclear, that accounts for the light elements lithium, berylium and boron which cannot survive in stellar interiors because they are destroyed by proton capture

the process of making carbon prints

(computing, Unix) A process that is not currently able to receive input from its controlling terminal.

An engineering discipline comprising the production of forest products, such as pulp and paper, construction materials, and tall oil.

(chemistry) any of several industrial processes that either use or manufacture sodium hydroxide, but especially a method of making paper from wood pulp

(chemistry, historical) An early industrial method of producing sodium carbonate. It involved two stages: production of sodium sulfate from sodium chloride, followed by reaction of the sodium sulfate with coal and calcium carbonate to produce sodium carbonate.

Any of many techniques in which data is retrieved, stored, classified, manipulated, transmitted and/or reported in such a way as to generate information; especially such processing using computers.
