This season of Law & Order: CI remained in its time slot of NBC Sunday's at 9PM/8c, its final season in this slot on NBC; its move to Tuesdays in the sixth season caused a ratings decline. During the 2005–2006 network TV season episodes were up against episodes of Desperate Housewives on ABC and episodes of Family Guy and American Dad! on Fox. The show "roller coasted" in the ratings with the competition, but NBC executives were impressed with the 11 million viewers per week it was able to retain.
Vacancy is an EP by Joseph Arthur released on May 11, 1999. Released by the independent label Undercover out of Portland, Oregon, Vacancy is a hand packaged, limited edition that was assembled one at a time by two people at Undercover. Each one was pressed and die-cut, then assembled and folded by hand. Vacancy was limited to 10,000 copies worldwide—5,000 to the US and 5,000 to Europe, the UK and France. The EP's sleeve design was nominated in 1999 for a Grammy Award for Best Recording Package. Joan Osborne plays acoustic guitar on "Crying on Sunday."
Vacancies occur naturally in all crystalline materials. At any given temperature, up to the melting point of the material, there is an equilibrium concentration (ratio of vacant lattice sites to those containing atoms). At the melting point of some metals the ratio can be approximately 1:1000.
It is the simplest point defect. In this system, an atom is missing from its regular atomic site. Vacancies are formed during solidification due to vibration of atoms, local rearrangement of atoms, plastic deformation and ionic bombardments.
The creation of a vacancy can be simply modeled by considering the energy required to break the bonds between an atom inside the crystal and its nearest neighbor atoms. Once that atom is removed from the lattice site, it is put back on the surface of the crystal and some energy is retrieved because new bonds are established with other atoms on the surface. However, there is a net input of energy because there are fewer bonds between surface atoms than between atoms in the interior of the crystal.
