Stenotrophomonas maltophilia. Stenotrophomonas maltophilia is an aerobic, nonfermentative, Gram-negative bacterium. It is an uncommon bacterium and human infection is difficult to treat. Initially classified as Bacterium bookeri, then renamed Pseudomonas maltophilia, S. maltophilia was also grouped in the genus Xanthomonas before eventually becoming the type species of the genus Stenotrophomonas in 1993. S. maltophilia is slightly smaller (0.7â1.8 Ã 0.4â0.7 Î¼m) than other members of the genus.
The Moon is a Harsh Mistress is one of the high points of modern science fiction, a novel bursting with politics, humanity, passion, innovative technical speculation, and a firm belief in the pursuit of human freedom. The Moon is a Harsh Mistress is the winner of the 1967 Hugo Award for Best Novel.
As the Moon orbits Earth, we see lunar phases as the amount of the Moon's sunlit face visible to us varies. At full Moon, we can see the entire illuminated side. At quarter Moon, only half the sunlit side can be seen. At new Moon, the sunlit face points away from us, and the Moon is all but invisible from Earth. The time between successive full Moons is one synodic month. The time taken for the Moon to return to the same position in the sky, relative to the stars, is one sidereal month. Because of Earth's motion around the Sun, the synodic month is about 2 days longer than the sidereal month. A lunar eclipse occurs when the Moon enters Earth's shadow.
