Long lifetimes are required for AMTEC (or sodium heat engine) components for aerospace and terrestrial applications, and the high heat input temperature as well as the alkali metal liquid and vapor environment places unusual demands on the materials used to construct AMTEC devices. In addition, it is important to maximize device efficiency and power density, while maintaining a long life capability. In addition to the electrode, which must provide both efficient electrode kinetics, transport of the alkali metal, and low electrical resistance, other high temperature components of the cell face equally demanding requirements. The beta{double prime} alumina solid electrolyte (BASE), the seal between the BASE ceramic and its metallic transition to the hot alkali metal (liquid or vapor) source, and metallic components of the device are exposed to hot liquid alkali metal. Modification of AMTEC components may also be useful in optimizing the device for particular operating conditions. In particular, a potassium AMTEC may be expected to operate more efficiently at lower temperatures.

Video footage from The Black Academy of Arts and Letters advertising the documentary drama play titled "The Azusa Street Revival" celebrating the history of William J. Seymour within the pentecostal religious movement in 1906. The docudrama appeared on The Gospel Light Showcase. The footage shows clips from the performance between interviews of the two main actors.

Newspaper clipping from the Dallas Morning News, originally published by the Religious News Service, dated November 2, 1991. The article discusses the Rev. Jerry Falwell's claim that a group of homosexuals intended to kill him at the Hollywood Roosevelt Hotel in Los Angeles, in October 1991. The article quotes Falwell's description of the event in a fund-raising letter mailed to Falwell's supporters.
