Unification: An international aerospace information issue

Science and technology projects are becoming more and more international and interdisciplinary. Other parts of the world, notably Europe, are increasingly powerful players in the aerospace business. This change has led to the development of various aerospace information initiatives in other countries. With scarce resources in all areas of government and industry, the NASA STI Program is reviewing its current acquisition and exchange practices and policies to factor in the changing requirements and new opportunities within the international community. Current NASA goals and activities are reviewed with a view toward developing a scenario for establishing an international aerospace data base, maintaining compatibility among national aerospace information systems, eliminating duplication of effort, and sharing resources through international cooperation wherever possible

Parrhesia: The Aesthetics of Arguing Truth to Power

Parrhesia is the rhetorical figure of dissent par excellence. The essay argues that parrhesia is understood as risky argumentation within the rhetorical tradition. The relation of frank speech and flattery has been a core discussion about the predicaments of advocacy since Greece and Rome. Whereas Foucault models the term primarily from the aesthetic enactments of Euripides, the essay studies parrhesia as a mutually implicating struggle articulated in Sophoclean drama. Dilemmas of wartime dissent found in United States Congressional debate over Iraq are presented as a contemporary case study

Unification: An international aerospace information opportunity

Science and technology projects are becoming more and more international and interdisciplinary. Other parts of the world, notably Europe, are increasingly powerful players in the aerospace industry.

With scarce resources in all areas of government and industry, the NASA STI Program is reviewing its current acquisition and exchange practices and policies to factor in the changing requirements and new opportunities within the international community.

New mineralogical data on platinum-group minerals from the Río Santiago alluvial placer, Esmeraldasprovince, Ecuador

Mineralogical studies on platinum-group minerals found in placer deposits from the Río Santiago (Ecuador) are scarce. In this investigation, one sample collected from the Río Santiago alluvial placer was studied via a multi-disciplinary approach, including optical microscopy, scanning electron microscopy, electron microprobe, and Raman spectroscopy. Whole-rock geochemistry data of the sample confirms elevated Au and platinum-group elements contents and the chondrite-normalized pattern reveals pronounced positive Ir and Pt nomalies. Free grains of platinum-group minerals were separated via hydroseparation techniques and identified as: i) Pt-Fe alloy (Pt3Fe), ii) tulameenite (Pt2FeCu) and iii) hongshiite (PtCu). The most abundant platinum-group mineral is Pt-Fe alloy (85%) that occasionally hosts cuprorhodsite (CuRh2S4) inclusions. Although the primary source remains unknown, the geochemical and mineralogical data suggests that the source of platinum-group minerals in the Río Santiago alluvial placer is a mafic-ultramafic Ural-Alaska type complex. Possible primary sources are the mafic and ultramafic rocks found in the mafic basement of the coastal region and the Western Cordillera (Piñón, San Juan and Pallatanga units), which derive from the Late Cretaceous Caribbean Colombia Oceanic Plateau (CCOP)

A Study of the Absorption of Hydrogen Bromide by Cinnamic Acid in the Presence of Ultra Violet Light

In the absorption of various reagents at the double bond of organic compounds it has been noted that in some cases a different product was obtained when the absorption was carried out in the presence of ultra-violet light. This difference has been frequently explained on the basis that the polarity of the reagent being absorbed was changed by the ultra-violet light. The question has been raised as to whether the difference was actually due to the change in polarity in the double bond

3. Launching the New Enterprise

As the academic year of 1945-46 approached, the intensity of activity in preparation for actually opening the school in the fall term became overwhelming. Incredible though it may seem, Ives and Day were able in a period of a few weeks to assemble the nucleus of a faculty, several of whom formed a continuing source of counsel and advice both during the school’s formative years and thereafter.

Procesos de Ingeniería de Requerimientos basados en modelos de madurez orientados a la certificación ISO 9001

En el marco de la industria del software en la Argentina la certificación de la calidad de software contribuye a la competitividad del sector productivo. La Ingeniería de Requerimientos (IR) es una parte fundamental del proceso de desarrollo de software, dado que pobres prácticas en esta etapa afectan significativamente el éxito de un proyecto. En esta línea de trabajo interesa analizar en qué medida la norma ISO 9001:2008 considera las buenas prácticas de la IR, para ello se estudiaron modelos de madurez de IR y se realizó una evaluación de proceso de IR antes y después de la certificación de la mencionada norma de calidad en las empresas del Polo IT Corrientes. Se concluye que la norma mejora el proceso de IR en ciertas áreas, pero no en todas. Actualmente, en base a los resultados obtenidos, se trabaja en la definición de procesos de IR que cumplan los requisitos de la norma ISO 9001:2008 y aseguren niveles altos de madurez de IR, basado en el modelo Uni-REPM.Eje: Ingeniería de SoftwareRed de Universidades con Carreras en Informática (RedUNCI
