... A nasty dispute between the Strategic Defense Initiative Organization (SDIO) and the space-science community was narrowly averted early this year when SDI officials backed down on a planned launch of a satellite with a Russian-built nuclear reactor on board. ... Early Soviet space reactors orbited for two to three months, and two Soviet Topaz 1 experiments, one for six and one 12 months, created radiation belts that disrupted the operation of scientific satellites. ...

... In this lecture, we will introduce addition and multiplication that turn the set of (equivalence classes of) species into a commutative semiring with unity. De nition. Let F and G be two combinatorial species. The sum of species is de ned as follows. ... Each of the three generating series associated with the sum of species is equal to the sum of corresponding series: (F +G)(x) = F (x) +G(x); ( ^ F +G)(x) = ~ F (x) + ~ G(x); Z F+G = Z F + ZG : Examples. ...
