Fences and profanations: Questioning the sacredness of urban design

Adopting an impure and contingent conception of urban design as a biopolitical apparatus, along the theme of urban informal squatter-occupied spatialities, this paper searches for an alternative narrative of urban design. It presents a theoretical and analytical framework developed around Michel Foucault's and Giorgio Agamben's spatial ontology and political aesthetics as an aggregate source toward recalibrating the approach to urban design research, pedagogy and practice, integrating the debate around the dispositif and its profanation. Critically engaging with the complexity and contradictions of the current neoliberal urban design practice—articulated as a complex urban apparatus instrumental to regimes of security and control—the paper explores the conceptual tool of profanation as a potential antidote to the sacred production of the neoliberal city. The act of profaning the urban realm, of ‘returning it to the free use of men’, is approached through the lens of a design research initiative in a squatter-occupied space in Rome, Italy. The narrative that emerges from this theoretically inspired action research points to an alternative practice that can be read as a site of resistance in reclaiming the intellectual productivity of urban design theory and research

Evolución del pensamiento acerca de la Gravedad

Siendo, generalmente, las leyes el resultado de una o más hipótesis o teorías que han ido preparando el camino para sus enunciados definitivos, y no siéndolo, como a veces se ha creído, la eclosión esporádica, espontánea y sorpresiva de una mente superior, justo es pensar que el método histórico es el que más se acomoda al espíritu, para que éste interprete el contenido y evolución progresiva integral de tales formulaciones científicas

Three-level approach to quality programs for research, development and production

A primary mission of the Los Alamos National Laboratory is to develop nuclear weapons systems for the Department of Defense. The activities included in this effort cover a broad spectrum, ranging from pure research to routine production. In order to provide a workable framework for a comprehensive quality assurance program for these varied activities, we have proposed a three-level structure of quality plans, corresponding to a rough classification of the weapons work into three general categories. These categories are: (1) research into materials and processes, and preliminary development; (2) design, development, and fabrication of prototype components; (3) routine production, analysis, or refinement activities. The first category requires a quality program to assure the validity, reliability, and retrievability of the information developed; this is accomplished by a conscientious application of what is generally recognized as good laboratory practice. The second category requires in addition a strong emphasis on design review and inspection. For the third category, a comprehensive quality program is appropriate

Calificación del proceso de fabricación de lingotes y barrotes de Zry-4 empleando 100% de material de reciclo

Los discos separadores utilizados en los elementos combustibles de Atucha I, son producidos por el sector Fundición de Conuar Fae S. A. y fabricados a partir de lingotes de Zry-4 empleando 100% de material de reciclo desde 1998. El presente trabajo muestra las medidas tomadas para el desarrollo y adaptación de los métodos productivos y de control y que culminaron con la calificación del proceso de fabricación. Se destaca el trabajo conjunto entre Conuar Fae S. A. como ejecutor del proyecto y CNEA/IEC como ente calificador, en el logro de este importante objetivo que se mantiene desde hace 5 años.Fil: Bunte, C.. Universidad Tecnológica Nacional.

A case of atrial fibrillation induced by inhaled fluticasone propionate

Atrial fibrillation (AF) is the most common rhythm disorder observed in clinical practice. Several case reports and case-control studies have associated this condition with the use of systemic corticosteroids. However, to our knowledge, no case of AF induced by inhaled corticosteroids has been reported in the literature. We describe here the case of a 15-year-old boy who reported a paroxysmal AF with fast ventricular response after the administration of fluticasone propionate, which resolved after discontinuation of the drug. Use of the Naranjo adverse-drug-reaction probability scale indicated a possible relationship between the patient's development of AF and fluticasone propionate therapy. More studies are needed to confirm the association between this arrhythmia and the use of high doses of inhaled corticosteroids. Data from this report already suggest that clinicians should be aware of the possibility of adverse cardiovascular reactions when corticosteroids are prescribed also as inhaled preparations
