Biography
Nicholas H. Heck
Captain Nicholas H. Heck (1 September 1882 – 21 December 1953) was a career officer of the United States Coast and Geodetic Survey Corps. A leading geophysicist of his time, Heck made important contributions in the study of seismology and oceanography. He also revolutionized hydrographic surveying by developing the wire-drag surveying technique and introduced radio acoustic ranging into Coast

Stylite
A stylite (from Greek στυλίτης, stylitēs, "pillar dweller", derived from στῦλος, stylos, "pillar", Classical Syriac: ܐܣܛܘܢܐ‎ ʼasṯonáyé) or pillar-saint is a type of Christian ascetic who lives on pillars, preaching, fasting and praying. Stylites believe that the mortification of their bodies would help ensure the salvation of their souls. Stylites were common in the early days of the Byzantine Empire. The first known stylite was Simeon Stylites the Elder who climbed a pillar in Syria in 423 and remained there until his death 37 years later.

Track Warrant
Track warrants are systematized permissions used on some railroad lines to authorize a train's use of the main line. Dispatchers issue these permissions to train crews instead of using signals. The crews receive track warrants by radio, phone, or electronic transmission from a dispatcher.

Grain Boundary Sliding
Grain Boundary Sliding (GBS) is a material deformation mechanism where grains slide against each other. This occurs in polycrystalline material under external stress at high homologous temperature (above ~0.4) and low strain rate and is intertwined with creep. Homologous temperature describes the operating temperature relative to the melting temperature of the material. There are mainly two types of grain boundary sliding: Rachinger sliding, and Lifshitz sliding. Grain boundary sliding usually occurs as a combination of both types of sliding. Boundary shape often determines the rate and extent of grain boundary sliding. Many people have developed estimations for the contribution of grain boundary sliding to the total strain experienced by various groups of materials, such as metals, ceramics, and geological materials. Grain boundary sliding contributes a significant amount of strain, especially for fine grain materials and high temperatures. It has been shown that Lifshitz grain boundary sliding contributes about 50-60% of strain in Nabarro-Herring diffusion creep. This mechanism is the primary cause of ceramic failure at high temperatures due to the formation of glassy phases at their grain boundaries.

Apple Network Server
The Apple Network Server (ANS) was a line of PowerPC-based server computers designed, manufactured and sold by Apple Computer, Inc. from February 1996 to April 1997. It was codenamed "Shiner" and originally consisted of two models, the Network Server 500/132 ("Shiner LE", i.e., "low-end") and the Network Server 700/150 ("Shiner HE", i.e., "high-end"), which got a companion model, the Network Server 700/200 (also "Shiner HE") with a faster CPU in November 1996. The machines were not a part of the Apple Macintosh line of computers; they were designed to run IBM's AIX operating system and their ROM specifically prevented booting the classic Mac OS. This makes them the last non-Macintosh desktop computers made by Apple to date. The 500/132, 700/150, and 97 sold in the U.S. market for $11,000, $15,000 and $19,000, respectively. Apple Network Servers are not to be confused with the Apple Workgroup Servers and the Macintosh Servers, which were Macintosh workstations that shipped with server software and used Mac OS; the sole exception, the Workgroup Server 95—a Quadra 950 with an added SCSI controller that shipped with A/UX—was also capable of running Mac OS. Apple did not have comparable server hardware in their product lineup again until the introduction of the Xserve in 2002. The product's short lifespan is attributed to significant financial troubles at Apple in early 1997. CEO Gil Amelio cancelled both Network Server and OpenDoc in the same meeting as it was determined that they were low priorities.
