An identical question was asked on
http://answers.semanticweb.com/questions/25123/namespaces-for-nq-files
which explains why the original email has two spaces before "jena" --
otherwise word perfect (it said "virtuoso and jena").
Different name attached to it. Written today.
Maria - please consolidate the answers across routes to asking the
question so someone coming across the question via one route benefits
from the answers on the other route.

As I stated there and as Joshua has already stated no NQuads does not
support syntax compressions like namespace prefixes.
For serialising datasets you may want to look at TriG instead
(http://www.w3.org/TR/trig/), your example rewritten as valid TriG:
@base <http://example.org/alice/foaf.rdf#> .
<d> { <a> <b> <c> . }

Just like .n3 format allows for namespaces of the following form:
@base <http://example.org/alice/foaf.rdf#>
<a> <b> <c>.
Is it also possible to write namespaces in .nq format such that jena
accepts them. I mean is the following format valid for jena (in .nq
format).
@base <http://example.org/alice/foaf.rdf#>
<a> <b> <c> <d>.
Notation3 (N3) is a human readable and writable format with lots of
syntactic sugar to make RDF authoring easy.
N-Quads [1] is "a line-based syntax for an RDF datasets", and more
closely related to N-Triples [2]. These just one have triple per
line, and don't support @prefix or @base. They're very quick to read
and write (by machine), split and combine, though.
