The pi used there is not the standard (italic) pi, but the upright
one. It's a requirement of the journal the paper was submitted to,
that italic is reserved for variables while upright is for constants
(and bold for vectors, sans serif for tensors). Hence pi, e, i, gamma
(the euler number) are all upright in the paper, and were entered
using the commands \uppi, \mathrm{e}, \mathrm{i}, \upgamma, as
allowed by the lucidabr package with option [vargreek].

Similarly the math italic used is not the standard one (looking like
just a slanted version of math upright), but the alternate math
italic font (with letter shapes different from those in math
upright). Using this alternate math italic is the default setting of
the lucidabr package, and standard math italic are obtained with the
[mathitalic2] option.
