Tomahawk engine/air-frame compatibility tests at the Naval Air Propulsion Center (NAPC), Arnold Engineering Development Center (AEDC), and in captive carry flight tests are discussed. A chronological history of these tests examines the test objectives, test configurations, and results. An emphasis on the two most recent ground tests at NAPC and AEDC is given with the tests compared in terms of repeatability of results. In the process, the major parameters effecting engine surge in the Tomahawk Cruise Missile are identified and quantified.

Over Time

This study was designed to investigate the natural history of atlantoaxial instability in individuals with Down syndrome and to determine whether significant changes in C1-C2 relationship are taking place over time. Although more than 400 patients with Down syndrome who are presently followed at the Child Development Center had cervical spine radiographic examinations in the past, only 141 patients who had serial radiological examinations and whose radiographs were available for reevaluation participated in this study. The results of our investigations revealed that there were only minor changes (1 to 1.5 mm) of atlanto-dens interval measurements over time in 130 (92%) patients with Down syndrome. Eleven patients (8%) had changes of atlanto-dens interval measurements between 2 and 4 mm over time; however, none of these patients had any clinical symptoms. The analyses of data obtained from several subgroups (males and females, various age groups, and patients with and without atlantoaxial instability) did not show any significant changes of atlanto-dens interval measurements of successively obtained radiographs. Our recommendations for and rationale of routine screening for atlantoaxial instability and follow-up examinations are discussed in detail.

Chapter 5 explores "Thai Town" in East Hollywood (established in 1999) to highlight the role of culinary tourism in Thai American struggles for a right to the global city. It charts the history of Thai Town's development as a product of Thai community leaders, specifically the Thai Community Development Center, and Los Angeles city officials’ attempt to parlay Thai cuisine's popularity into political visibility, civic engagement, social justice activism, and urban redevelopment. While playing on cuisine-driven multiculturalism allowed Thais to use food, specifically culinary tourism, to root identity and community in a physical place, the chapter argues that heritage commodification in Thai Town also constricted a right to the global city, because it was geared toward a neoliberal vision of multiculturalism that sought to highlight the position of Los Angeles in the global capitalist economy. The chapter also includes a discussion of the 1995 El Monte slave-labor case.
