Estudio de la Factibilidad de formación de Estudio de la Factibilidad de formación de Recubrimientos Protectores por CVD en Lecho Fluidizado Sobre la Aleación de Titanio

Pérez, Francisco J; Lira-Olivares, Joaquín; Hierro, María P.; Tirado, Jesús
2005-01-01

Resumen en español Se  ha estudiado la factibilidad de la formación de recubrimientos protectores de aluminio por deposición química en fase vapor por reactor de lecho fluidizado (CVD-FBR) sobre la aleación de titanio Ti-15Mo-3Al.  Antes de realizar los experimentos, se utilizaron los cálculos termoquímicos del sistema  usando el método de minimización de energía libre por el software HSC Chemistry, como factor de diseño de las condiciones al recubrir  la aleación de titanio (mas) con  Al. Los recubrimientos fueron caracterizados por análisis morfológico superficial y de la sección transversal a través  de microscopía electrónica de barrido (SEM) empleando espectroscopia de dispersión de energía  (EDS), mapa de distribución de los elementos y difracción de rayos-X. Se encontró que para las condiciones de H2/HCl=31/1 y H2/HCl=15/1, respectivamente, ambas  durante una hora, a una temperatura de 395ºC, la aleación de titanio Ti-15Mo-3Al presenta una  capa de aluminio muy  delgada. Los espesores de las capas de aluminio obtenidas para las relaciones de gases de H2/HCl=31/1 y H2/HCl=15/1 son de 0,58 y 0,87mm respectivamente. De acuerdo a estos resultados, el uso de CVD-FBR es viable para el proceso de deposición de aluminio sobre la aleación de titanio Ti-15Mo-3Al. Resumen en inglés The feasibility of the formation of aluminum protective coatings by chemical vapor deposition in fluidized bed reactor (CVD-FBR) on the titanium alloy Ti-15Mo-Al and the influence of temperature and gas molar relation on the deposition process have been studied.  Before performing the experiments, thermochemical calculations were attained using the free-energy minimization method provided by the HSC Chemistry software, as a designing factor of conditions to deposition of (mas) Al on titanium alloy. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), mapping elements and -X-Ray diffraction have been employed to characterize the coatings obtained. For conditions of H2/HCl=31/1 and H2/HCl=15/1, both at 395ºC for one hour, the titanium alloy Ti-15Mo-Al exhibits a very thin aluminum layer. The thicknesses of the aluminum layers are 0.58 and 0.87mm for gas relations of H2/HCl=31/1 and H2/HCl=15/1 respectively. According to these results, the CVD-FBR is viable for the process of aluminum deposition on y the titanium alloy Ti-15Mo-Al.

Globalización y ciudades en América Latina: ¿Es el turno de las ciudades intermedias en la Argentina?

Usach, Natalia; Garrido Yserte, Ruben
2009-12-01

Resumen en español El documento sostiene que la economía global ha impreso cambios en la tradicional configuración estrictamente jerárquica de los sistemas urbanos. La organización emergente tiende a ser más abierta y a privilegiar las relaciones horizontales entre ciudades. Se recogen algunas evidencias que dan cuenta de la relativa inserción de las principales ciudades de América Latina en algunas redes globales, para posteriormente centrarse en el caso argentino. Se plantea la ten (mas) sión existente entre la tendencia forjada históricamente hacia la concentración geográfica de la población y de las actividades económicas en la metrópolis de Buenos Aires y otras tendencias un tanto más recientes hacia la dispersión, destacándose el papel de las ciudades intermedias. El documento concluye reflexionando sobre la necesidad de abordar los estudios sobre los flujos entre ciudades, los patrones de dependencia espacial entre las mismas y el papel de las políticas públicas en este proceso. Resumen en inglés The paper argues that the global economy has produced changes in the hierarchical configuration of urban systems. The emerging organization tends to be more open and set up more horizontal relations among cities. There are some evidences that indicate the relative insertion of the main Latin-American cities in global networks. The paper shows the empirical evidence available to Latin-American cities and, specially, related to the Argentine case. It evaluates the tension b (mas) etween the historically forged trend toward geographic concentration of population and economic activities in the metropolis of Buenos Aires and other somewhat more recent trends towards dispersion, emphasizing the role of intermediate cities. The paper concludes reflecting on the importance of flows between cities, the patterns of spatial dependency between them and the role of public policy.

Seguridad y libertad: lugar y espacio en las relaciones familia - individuo en Bogotá/ Security and Liberty: Space and Place in Family-Individual Relations in Bogotá/ Seguridade e liberdade: lugar e espaço nas relações família indivíduo em Bogotá

Salazar, Oscar Ivan
2008-04-01

Resumen en portugués Algumas das idéias generalizadas referidas à cultura urbana nas cidades modernas são: a fragmentação do espaço e a individualização ligada ao anonimato. Este artigo pretende mostrar as maneiras como se expressam ditas características nas práticas residenciais de famílias e indivíduos da classe média em Bogotá. As práticas residenciais destas populações se configuram atualmente em torno do que eu chamo como regiões individuais e regiões familiares. Estas (mas) formas de regionalização do espaço urbano surgiram de processos sociais de longo e mediano prazo, que têm fortalecido a individualização da sociedade, reduzido o número de famílias e lares e redefinido os significados, formas e usos da moradia. Argumentase que a fragmentação do espaço está mais relacionada com a dispersão do que com a destruição da estrutura familiar e que as regiões familiares constituem uma estratégia de adaptação e configuração da vida urbana em Bogotá. Resumen en español Algunas de las ideas más generalizadas respecto a la cultura urbana en las ciudades modernas son la fragmentación del espacio y la individualización asociada al anonimato. Este artículo pretende mostrar las maneras como se expresan dichas características en las prácticas residenciales de familias e individuos de clases medias en Bogotá. Las prácticas residenciales de estas poblaciones se configuran actualmente en torno a lo que denomino regiones individuales y reg (mas) iones familiares. Estas formas de regionalización del espacio urbano son el resultado de procesos sociales de largo y mediano plazo que han fortalecido la individualización de la sociedad, reducido el tamaño de las familias y los hogares, y redefinido los significados, formas y usos de la vivienda. Se argumenta que la fragmentación del espacio está relacionada con la dispersión, antes que con la destrucción de la estructura familiar, y que las regiones familiares constituyen una estrategia de adaptación y configuración de la vida urbana en Bogotá. Resumen en inglés Space fragmentation, anonymity and individualization are some of the most generalized ideas about urban culture in modern cities. This article shows the expression of those characteristics in dwelling practices of middle class families and individuals in Bogotá. Dwelling practices are configured toward individual regions and familiar regions. Both are regionalization ways of urban space, and are produced by a long and middle term social processes that have strengthen ind (mas) ividualization of society, reduced family and home size, and redefined meaning, form and use of urban housing. I argue that space fragmentation is associated to dispersion instead of destruction of family structure; in addition, familiar regions are an adaptation strategy that configures urban life in Bogotá.

El diseño en la integración de los sistemas naturales y artificiales

Curiel Carías, Ernesto C
2003-08-01

Resumen en portugués As explicações sobre a origem das alterações extremas que está introduzindo a atividade humana na biosfera aludem em forma recorrente a causas não materiais vinculadas a percepção, valoração e concepção de nossas relações com o mundo natural. O vínculo entre estas causas não materiais e o entorno material que elas geram, o ocupa em boa medida a atividade do desenho. O número, heterogeneidade e dispersão de fatores que incidem nesta atividade, dificultam (mas) com freqüência o dispor de uma visão integrada de seu rol na crise. No presente ensaio se revisam algumas discussões recentes relativas às dissociações entre a lógica que pauta a estrutura e dinâmica dos sistemas naturais, e aquela outra que tem prevalecido na dos sistemas artificiais; lógicas que de maneira contraditória informam e condicionam o oficio do desenho. Igualmente se adianta uma revisão sobre certas reflexões contemporâneas que procuram conciliar esses supostos do desenho, com olhos a garantir a viabilidade no tempo de uma ecologia global. Resumen en español Las explicaciones acerca del origen de las alteraciones extremas que está introduciendo la actividad humana en la biosfera, aluden en forma recurrente a causas inmateriales vinculadas a la percepción, valoración y concepción de nuestras relaciones con el mundo natural. El vínculo entre estas causas inmateriales y el entorno material que ellas generan, lo ocupa en buena medida la actividad del diseño.

En el presente ensayo se revisan algunas discusiones recientes relativas a las disociaciones entre la lógica que pauta la estructura y dinámica de los sistemas naturales, y aquella otra que ha prevalecido en la de los sistemas artificiales; lógicas que de manera contradictoria informan y condicionan el oficio del diseño. Igualmente se adelanta una revisión sobre ciertas reflexiones contemporáneas que procuran conciliar esos supuestos del diseño, con miras a garantizar la viabilidad en el tiempo de una ecología global. Resumen en inglés The explanations about the origin of the extreme alterations introduced in the biosphere by human activities deal, recurrently, with immaterial causes linked to the perception, evaluation and conception of our relations with the natural world. The relationship between these immaterial causes and the material surroundings is dealt with, to a large extent, by the activity of design. The number, heterogeneity and dispersion of factors that affect this activity blur an integr (mas) ated view about the role of design in the crisis. In this essay, some recent discussions are reviewed concerning the dissociations between the logic that rules the structure and dynamics of the natural systems, and that other logic that has prevailed in the artificial systems. Both logics feed and determine the craft of design in contradictory ways. Additionally, some contemporary considerations are reviewed trying to reconcile those assumptions of design, with the purpose to assure the viability, in time, of a global ecology.

Resumen en español En base a un análisis estadístico de los principales parámetros morfomé tricos, se hace una caracterización hidrológica de la cuenca alta del arroyo Las Lajas. En particular se discute la influencia de la estructura y litología sobre el diseño de la red de drenaje. La cuenca alta del arroyo Las Lajas drena una superficie aproximada de 41 km² y se desarrolla sobre un basamento plutónico-metamórfico del Precámbrico-Paleozoico superior. El relieve está conformad (mas) o por serranías bajas, valles de fondo plano, con relleno aluvial y coluvial. La precipitación media anual es de 860 mm. La forma de la cuenca está parcialmente controlada por la Falla Las Lajas. Los parámetros morfométricos utilizados son: densidad de drenaje, frecuencia de cursos de primer orden, rugosidad de la cuenca, relación de bifurcación, relación de longitudes y relación de elongación. Estos se aplicaron a subcuencas de tercer orden, agrupadas en un sector oriental y otro occidental, delimitados por la Falla Las Lajas. De cada parámetro medido se obtuvieron estadísticos de posición y de dispersión y se realizaron, previa prueba de normalidad y de correlación, tests estadísticos, análisis de agrupamiento y factorial. El resultado no demuestra que exista un control litológico sobre el diseño de la red de drenaje. Un análisis de agrupamiento sobre las subcuencas indica una división en dos conjuntos que no muestran una relación obvia con la estructura ni la litología del sustrato. Resumen en inglés The Las Lajas Creek mountainous drainage basin is characterized through the analysis of morphometric parameters, with the main purpose of studying the possible control of substrate lithology and structure on the drainage pattern. The basin drains an area of approximately 41 km², on a Precambrian-upper Paleozoic plutonic-metamorphic substrate. The basin lies in an area of moderate-elevation ranges, and planar valleys filled with alluvial and coluvial deposits. The basin i (mas) s controlled by the active Las Lajas Fault. Morphometric parameters studied are: drainage density, frequency of first order streams, bifurcation relation, stream length relation, and elongation relation. These parameters were computed for third-order subwatersheds in the Las Lajas Creek basin to test the hypothesis that substrate lithology controlled drainage morphometry. The statistical analysis failed to demonstrate this hypothesis. Cluster analysis indicates a grouping of subwatersheds in two major sets that do not show obvious relations to either structure or lithology of the substrate.

Resumen en español Se estudió una sucesión sedimentaria que aflora en el sudeste de la Cuenca Neuquina, en el departamento El Cuy (Río Negro). La misma incluye a las formaciones Huincul y Lisandro que integran el Subgrupo Río Limay (Grupo Neuquén), y han sido asignadas al Cenomaniano- Turoniano. Se identificaron once litofacies de origen fluvial, tres litofacies de naturaleza eólica y dos litofacies volcaniclásticas. A partir de los agrupamientos en unidades genéticamente relacionad (mas) as se definieron siete elementos fluviales de intracanal, cuatro de planicie de inundación y cuatro eólicos. La distribución espacial y relaciones entre los elementos arquitecturales ha permitido reconocer sistemas fluviales agradantes de alta sinuosidad (SF-I y II), un sistema de abanico terminal (SAT) y campos de médanos barjanoides (SE). El análisis estratigráfico-secuencial permitió definir cinco Secuencias a partir de las relaciones espaciales y temporales de los elementos arquitecturales mayores y de la determinación de superficies estratigráficamente significativas. La base de la Formación Huincul está representada por el SF-I, caracterizado por un sistema de alta sinuosidad, con baja relación canales/planicie de inundación y abundantes depósitos de desbordes. Este tramo de la secuencia se interpreta como el Cortejo de Alta Acomodación (AA) de la Secuencia I (S-I). El sector cuspidal de la unidad está integrado por un sistema similar pero con una alta relación canal/planicie de inundación y constituye el Cortejo de Baja Acomodación (BA) de la Secuencia II (S-II). Se propone que la depositación de la Formación Huincul tuvo lugar bajo condiciones climáticas cálidas con un régimen de estacionalidad marcado. La Formación Lisandro se inicia con depósitos de un sistema distributario proximal de abanico terminal (SAT) que representan el Cortejo AA de S-II. De aquí en adelante es notoria la recurrencia de SE, caracterizando los Cortejos BA y una sucesión desde cuenca de inundación a distributarios proximales de SAT, integrando los Cortejos AA de las secuencias S-II, III, IV y V. La unidad se depositó bajo condiciones climáticas semiáridas permanentes. Las unidades estratigráficas estudiadas se consideran de carácter sinorogénico, con un control tectónico significativo en la definición del espacio de acomodación y un volcanismo principalmente activo durante la sedimentación de la Formación Huincul. La Formación Lisandro corresponde a un período de abrupto incremento en la tasa de subsidencia en la Cuenca Neuquina. Resumen en inglés In the Cuy Department, Rio Negro Province (Fig. 1), there are outcrops of the Late Cretaceous continental deposits of the Subgroup Rio Limay (Fig. 2), in virtually continuous exposures that allow detail studies and exploration of the architecture of the sedimentary bodies. This contribution presents the results of the sedimentological study and sequential stratigraphic analysis for the depositional period of the Huincul and Lisandro formations (Subgroup Río Limay). The o (mas) utcrops appear in the Planicie de Rentaría (Area A), with continuous sections longer than 3 km and Anfiteatro (Area B) with outcrops of more than 5 km (Fig. 1). In these areas we made detailed sedimentological profiles (Fig. 3), we described and interpreted lithofacies and architectural elements employing photograms and we defined stratigraphicaly significant discontinuities. We identified 11 fluvial lithofacies, 4 conglomerates (Gm, Gh, Gp and Gt), 5 sandstones (Sm, St., Sp, and Mr. Sh), and 2 pelitic (Fl and Fm), according to the nomenclature of Miall (1996). In addition, 2 volcaniclastic lithofacies, 1 primary pyroclastic lithofacies (Tlpm) and 1 volcaniclastic sineruptive lithofacies (TLpe) following criteria Mc Phie et al. (1993) were defined, and finally 3 eolic lithofacies (Spe, She and Sathya) (Fig. 4). These were grouped into 11 fluvial architectural elements and 4 eolic (Fig. 5). We have recognized channel elements (CHI) and CHII), intrachannel (LA, DAI, DAII, SBI and SBII) and floodplain (CRI, CRII, CS and OF). The eolic architectural elements include dunes (ED) and interdunes (DI, and WI FI). The paleoenvironments sedimentary include river systems, terminal fans and dune fields. The Sistema Fluvial I (SF-I) is integrated by LA, DAI, DAII, SBI, CHI, CRI, CRII and OF (Fig. 6). The meanders loops show, in most cases, complete filling sequences in which records of migration of large sand dunes are preserved which retain topsets deposits and the scrolls their undulating tops. The channel belts are separated by potent floodplain deposits, with frequent intercalation of levels of overflow both channelized or in mantle, and show a multilateral persistence in potent sections of the column. The crevasse splay exhibits paleosoils with low levels of development, frequent presence of gleyzed horizons and high degree of bioturbation. The general characteristics of the S-FI are proper of aggrading fluvial systems of high sinuosity. The Sistema Fluvial II (SF-II) is characterized by LA, DAI, DAII, SBI and to a lesser proportion, by CRI and OF (Fig. 6). The meanders loops often show preservation of the channel fill by lateral accretion with complete successions. Also the dunes preserve topsets deposits and the scrolls the original topography (Fig. 7). The frequency of conservation of filling phase of the abandoned channel with strong bioturbation and development gleyzed horizons suggests frequent avulsion by strangulation. The preservation of the floodplain is low, and it is characterized by intense bioturbation, and a high volcaniclastic participation in some reaches. We consider that the fluvial system model is of high sinuosity highly aggrading. The terminal fan system (Sistema Abanico Terminal) (TSS), characteristic of semiarid regions with strong seasonal climatology, is represented by CHII, CS or SBII and OF (Fig. 6). These constitute flooding basin deposits (CI), simple multiepisodic channel fillings corresponding to middle sections of the distributary plain and simple channels with development of small transversal cross bars and multilateral relations of distal distributary plain. The aeolian system (Sistema Eolico) (IS) consists of SD, DI, WD and FD. The spatial distribution of dunes and interdunes, the high dispersion of paleocurrents with a principal mode at the avalanche deposits and multiple stabilization surfaces suggest the development of a field of barchan dunes. In the element WI, we identified ferric and mottled halos and bioturbations that indicate the presence of paleosoils with gleyzed horizons (Retallack, 1976, 1990) which and characterize environments with good oxygenation. According to the temporal and spatial arrangement of the different paleoenvironments, their evolutionary trend and the analysis of significant discontinuity surfaces, we produced the stratigraphic sequence for the Subgroup Rio Limay (Fig. 8). The sequence starts with the Secuencia I, corresponding to the base of the Huincul Fm and is represented by SF-I, defined by belts of potent channels, isolated in floodplain deposits and with the development of overflow fans under conditions of rapid aggradation. The avulsion by overflow crevasse splay was the control mechanism of the system. The development of composite paleosoils in distal segments of the plain indicates the existence of long periods during which the channel band remained relatively stable poitions. The incorporation of volcaniclastic materials to fluvial deposits claims a volcanic activity close in time. The geometry and continuity of the sandy bodies and its proportion in relation to the floodplain deposits suggests periods of low frequency of avulsion/subsidence rate. The large-scale architecture observed is the equivalent to a High Accommodation System Track (Cortejo) (AA) with a ratio A/S close to 1 associated with a gradual decline in the base level under conditions of high sediment supply. A net surface (Discontinuidad D-IS-IS) is the basis of the sequence II, marked by an abrupt change in the fluvial architecture river (SF-II). The mechanism of lateral migration was by strangulation and abrupt cut of the bends. Only underdeveloped paleosoils in the abandoned channel fillings and the little preservation of the floodplain deposits are recognized. The stacking of channel belts signs out a reduction in the accommodation space. The top layer of Huincul Fm is interpreted as Lower Accommodation System Track (Cortejo) (BA). The Discontinuity IIC (D-IIC) marks the base of Lisandro Fm, which is an surface of fluvial flooding defining the expansion of a terminal fan system associated with an abrupt increase in the accommodation space and rapid progradation of the facies of an environment of intermediate distributary plain. This stretch of the Sequence is interpreted as the High Accommodation System Track (Cortejo) (AA) of the Sequence II (S-II) was associated with a period of high subsidence. The deposits of terminal fans are covered by a wet eolian system (IS). The change in the depositional environment marks the beginning of the Sequence III (SIII), limited at the base by D-IIIS. The development of a field of parabolic dunes associated with environments dry, wet and flooded interdune indicates a gradual rise in the water table that, eventually, was above the depositional surface generating shallow lagoons. The shortterm climatic changes related with an increase in precipitation and the relative position of the water table controlled the development stabilization surfaces and the growth and migration of aeolian forms. We identified two supersurfaces (D-IV and DV, Fig. 18) which may be assigned to periods with an increase in the supply or availability of sediment climatically conditioned. Periodically, the interdune corridors were overrun by ephemeral streams associated with the flood basin environments of SAT during flooding events. All deposits, characterized by a strong stacking of the eolian successions are interpreted as the Cortejo BA from the Sequence III. A new fluvial flood event marked by the Discontinuity VIC, is represented by facies flood basin, a distributary plain with the development of intertwined channels showing evidences of the SAT progradation. This sector is interpreted as the (Cortejo) AA System Track of S-III associated with a period of renewed subsidence. D-VIIS limits the base of the S-IV whose (Cortejo) BA System Track is similar to the previous Sequence and includes 3 supersurfaces (D-D-VIIIIX / X). The expansion of the flooding basin facies of a limited terminal fan at the base by D-XIC represents the base of the (Cortejo) AA System Track of the Sequence IV. Tabular units associated with a distal distributary plain that replaced towards the top by thick channels of low sinuosity close to the backbone of the system represent an progradation event of the SAT. The beginning of the Sequence V is marked D-XIIS associated with the development of a new SE. The architectural design of large scale is similar to that of the (Cortejos) BA System Tracks of the Sequences III and IV and includes supersurfaces D-D-XIII and XIV. Something similar occurs with the surface of fluvial flooding (D-XVC) on which we identified a prograding succession of SAT. The characteristics of the systems involved in the Lisandro Fm suggest a climate change to semi-arid conditions and low gradient in the depositional environment. The sequential stratigraphic analysis of the formations Huincul and Lisandro suggests that the deposits are sinorogénic and the different pulses of subsidence are registered in the (Cortejos) AA and BA System Tracks defined in this study.
