Nór (Old Norse Nórr) or Nori is firstly a merchantile title and secondly a Norse man's name. It is in Norse sources stated that Nór is the founder of Norway from which the land supposedly got its name. The name Norway does not derive from "Nór's way", but rather from the Norwegian "Nór rige" meaning "Nór's rule/kingdom": hence how Norwegian for Norway is "Norge".

nor- is a chemical acronym and prefix. It comes from the German nitrogen ohne Rest, "no residues at nitrogen."  Residues are groups such as a methyl-group that are part of a larger molecule. Despite the word "nitrogen", it is also used in reference to other "stripped-down" molecules. For example, a norbornyl group (bicyclo[2.2.1]heptane) is a bornyl group (1,7,7-trimethylbicyclo[2.2.1]heptane) lacking the three different methyls at carbons.

(conj.)
A negative connective or particle, introducing the second member or clause of a negative proposition, following neither, or not, in the first member or clause (as or in affirmative propositions follows either). Nor is also used sometimes in the first member for neither, and sometimes the neither is omitted and implied by the use of nor.
  

Not OR.
The Boolean function which is true if none of its inputs are true and false otherwise, the logical complement of inclusive OR. The binary (two-input) NOR function can be defined (written as an infix operator):
A NOR B = NOT (A OR B) = (NOT A) AND (NOT B)
Its truth table is:
A | B | A NOR B --+---+--------- F | F | T F | T | F T | F | F T | T | F
NOR, like NAND, forms a complete set of Boolean functions on its own since it can be used to make NOT, AND, OR and any other Boolean function:
NOT A = A NOR A
A OR B = NOT (A NOR B)
A AND B = (NOT A) NOR (NOT B)
