Development of a KSC test and flight engineering oriented computer language, Phase 1

Ten, primarily test oriented, computer languages reviewed during the phase 1 study effort are described. Fifty characteristics of ATOLL, ATLAS, and CLASP are compared. Unique characteristics of the other languages, including deficiencies, problems, safeguards, and checking provisions are identified. Programming aids related to these languages are reported, and the conclusions resulting from this phase of the study are discussed. A glossary and bibliography are included. For the reports on phase 2 of the study, see N71-35027 and N71-35029

The Controversial Passage of Proposition 227

When Proposition 227 passed in 1998, it essentially ended a thirty-year program of bilingual education in California of students with limited English proficiency, and replaced it with a controversial, year-long, intensive English-immersion program. Paying close attention to how each side of the debate was framed in televised programming and local newspapers, this paper examines why such a controversial law was able to pass by popular ballot. After researching the popular opinions of the previous program of bilingual education as well as the narrative of the state concerning how it views its immigrant populations, with the children of Latin American immigrants most heavily affected by the new law, this paper seeks to put the passage of Proposition 227 into perspective. When the initiative was proposed, it appeared to present a simple and concrete solution to a complex problem that had been brought to the attention of many Californians. Despite its strong political opposition both at the state and federal levels, without any concrete alternative solutions, the California voting public chose to put their faith in an untested solution. This suggests that voters in California are willing to take a chance with a controversial proposition rather than wait for legislative reform when it comes to an issue as important as the education of 1.4 million students. With California often being viewed as the up and coming trend setter in the United States when it comes to passing new laws, it becomes important to understand what is influencing voters within the state and how the sudden publicization of long-term issues can influence voters into passing questionable policies

Amenability of Certain Kansas Clays to Alumina Extraction by the Lime-Sinter Process

The development of the lime-sinter process of extracting alumina from clay and the potential use of this method for beneficiation of Kansas refractory clays have prompted the Geological Survey to make further investigations of alumina extraction from Kansas clays. The Geological Survey's original studies of the soda-lime-sinter process were conducted under conditions of stress during World War II and were directed exclusively toward the ultimate production of aluminum metal. The present study tests the applicability of the lime-sinter process to Kansas clays and is directed primarily toward the development of high-alumina refractory materials with the possible utility of Kansas clay as a source of ore for aluminum metal as a secondary consideration. Laboratory tests indicate that Kansas clays are amenable to treatment by the lime-sinter process for both of these ultimate products, and that 80 to 84 percent of the alumina contained in the samples tested can be extracted as a high-grade product by this relatively simple process

Numerical study of large-eddy breakup and its effect on the drag characteristics of boundary layers

The break-up of a field of eddies by a flat-plate obstacle embedded in a boundary layer is studied using numerical solutions to the two-dimensional Navier-Stokes equations. The flow is taken to be incompressible and unsteady. The flow field is initiated from rest. A train of eddies of predetermined size and strength are swept into the computational domain upstream of the plate. The undisturbed velocity profile is given by the Blasius solution. The disturbance vorticity generated at the plate and wall, plus that introduced with the eddies, mix with the background vorticity and is transported throughout the entire flow. All quantities are scaled by the plate length, the unidsturbed free-stream velocity, and the fluid kinematic viscosity. The Reynolds number is 1000, the Blasius boundary layer thickness is 2.0, and the plate is positioned a distance of 1.0 above the wall. The computational domain is four units high and sixteen units long
