Cruces, Mestizaje y Dislocación en la escritura de Enrique Vila-Matas, Augusto Monterroso y Macedonio Fernández

La presente exposición es parte de una investigación sobre la obra de Augusto Monterroso y se relaciona con mi proyecto de tesis de Doctorado, actualmente en curso. En el marco del I Congreso Internacional de Literatura y Cultura Españolas Contemporáneas, se ha pensado examinar los cruces e intersecciones que tienen lugar en y desde la escritura de Enrique Vila-Matas, Augusto Monterroso y Macedonio Fernández. Se utilizará para la indagación la siguiente metodología de trabajo: búsqueda, selección y análisis de textos de Enrique Vila-Matas, Augusto Monterroso y Macedonio Fernández, luego se propondrá el tratamiento de una problemática pensada a partir del trazado de las siguientes líneas temáticas: la reflexión sobre la escritura propia y la transformación de lo ya escrito en una suerte de mestizaje genérico, la reflexión sobre la escritura de los otros y su apropiación como cruce y resignificación de la "cosa literaria". Se tratará de analizar y demostrar que a partir del tratamiento de la ficción, los textos se asedian y son asediados por otras voces que una vez provocadas, se dislocan en una suerte de malla que trasciende el propio espacio textual y entabla nuevos diálogos e intercambios.

Enrique Díez-Canedo, Buenos Aires, 1936 : Selección de cartas recibidas

Una selección de cartas (hasta ahora no publicadas excepto una) provenientes en su mayoría del archivo de Enrique Díez-Canedo, embajador de la República española en Argentina desde julio de 1936 hasta febrero de 1937, ofrece la posibilidad de reconstruir con detalle las relaciones, movimientos e intrigas de la diplomacia hispano argentina en palabras de los protagonistas, así como de entender las complicaciones de su gestión y las razones de su precipitada dimisión del cargo de embajador, a menos de un año de haberlo asumido

Selective area growth of a- and c-plane GaN nanocolumns by molecular beam epitaxy using colloidal nanolithography

Selective area growth of a-plane GaN nanocolumns by molecular beam epitaxy was performed for the first time on a-plane GaN templates. Ti masks with 150 nm diameter nanoholes were fabricated by colloidal lithography, an easy, fast and cheap process capable to handle large areas. Even though colloidal lithography does not provide a perfect geometrical arrangement like e-beam lithography, it produces a very homogeneous mask in terms of nanohole diameter and density, and is used here for the first time for the selective area growth of GaN. Selective area growth of a-plane GaN nanocolumns is compared, in terms of anisotropic lateral and vertical growth rates, with GaN nanocolumns grown selectively on the c-plane

Wheel-Rail Contact Forces in High-Speed Simply Supported Bridges at Resonance

The response of high-speed bridges at resonance, particularly under flexural vibrations, constitutes a subject of research for many scientists and engineers at the moment. The topic is of great interest because, as a matter of fact, such kind of behaviour is not unlikely to happen due to the elevated operating speeds of modern rains, which in many cases are equal to or even exceed 300 km/h ( [1,2]). The present paper addresses the subject of the evolution of the wheel-rail contact forces during resonance situations in simply supported bridges. Based on a dimensionless formulation of the equations of motion presented in [4], very similar to the one introduced by Klasztorny and Langer in [3], a parametric study is conducted and the contact forces in realistic situations analysed in detail. The effects of rail and wheel irregularities are not included in the model. The bridge is idealised as an Euler-Bernoulli beam, while the train is simulated by a system consisting of rigid bodies, springs and dampers. The situations such that a severe reduction of the contact force could take place are identified and compared with typical situations in actual bridges. To this end, the simply supported bridge is excited at resonace by means of a theoretical train consisting of 15 equidistant axles. The mechanical characteristics of all axles (unsprung mass, semi-sprung mass, and primary suspension system) are identical. This theoretical train permits the identification of the key parameters having an influence on the wheel-rail contact forces. In addition, a real case of a 17.5 m bridges traversed by the Eurostar train is analysed and checked against the theoretical results. The influence of three fundamental parameters is investigated in great detail: a) the ratio of the fundamental frequency of the bridge and natural frequency of the primary suspension of the vehicle; b) the ratio of the total mass of the bridge and the semi-sprung mass of the vehicle and c) the ratio between the length of the bridge and the characteristic distance between consecutive axles. The main conclusions derived from the investigation are: The wheel-rail contact forces undergo oscillations during the passage of the axles over the bridge. During resonance, these oscillations are more severe for the rear wheels than for the front ones. If denotes the span of a simply supported bridge, and the characteristic distance between consecutive groups of loads, the lower the value of , the greater the oscillations of the contact forces at resonance. For or greater, no likelihood of loss of wheel-rail contact has been detected. The ratio between the frequency of the primary suspension of the vehicle and the fundamental frequency of the bridge is denoted by (frequency ratio), and the ratio of the semi-sprung mass of the vehicle (mass of the bogie) and the total mass of the bridge is denoted by (mass ratio). For any given frequency ratio, the greater the mass ratio, the greater the oscillations of the contact forces at resonance. The oscillations of the contact forces at resonance, and therefore the likelihood of loss of wheel-rail contact, present a minimum for approximately between 0.5 and 1. For lower or higher values of the frequency ratio the oscillations of the contact forces increase. Neglecting the possible effects of torsional vibrations, the metal or composite bridges with a low linear mass have been found to be the ones where the contact forces may suffer the most severe oscillations. If single-track, simply supported, composite or metal bridges were used in high-speed lines, and damping ratios below 1% were expected, the minimum contact forces at resonance could drop to dangerous values. Nevertheless, this kind of structures is very unusual in modern high-speed railway lines.

Aplicación del M.E.C. al estudio de sistemas elásticos con simetría axial

En este artículo se presenta la aplicación del Método de los Elementos de Contorno a la determinación del campo de desplazamientos y tensiones de sistemas axisimétricos en régimen elástico. Desarrollando asimismo, un procedimiento para la determinación de los coeficientes de las matrices de influencia que aparecen en el tratamiento numérico del problema. El estudio del estado tensional del sistema axisimétrico es de obvio interés en Ingeniería, pudiendo citarse entre otras las siguientes aplicaciones: estudio de vasijas de todo tipo, y cobrando plena actualidad las vasijas de los reactores nucleares; efecto de grietas y entallas; efecto de la colocación de zunchos de pretensado en depósitos de hormigon armado, etc. El tratamiento numérico de este tipo de problemas se produce como consecuencia de la dificultad de encontrar soluciones cerradas para las ecuaciones de campo que definen el problema, ecuaciones que aunque establecidas hace tiempo, sólo han sido resueltas en casos particulares. La ventaja de la utilización del M.E.C.,frente a los métodos de dominio, se pone de manifiesto en el estudio de este tipo de sistemas ya que la consideración de una malla monodimensional es suficiente para representar la discretización del contorno, produciendose una considerable reducción del tiempo de c��mputo.

Sampling strategies using the "accumulation chamber" for monitoring geological storage of CO2

Fundación Ciudad de la Energía (CIUDEN) is carrying out a project of geological storage of CO2, where CO2 injection tests are planned in saline aquifers at a depth of 1500 m for scientific objectives and project demonstration. Before any CO2 is stored, it is necessary to determine the baseline flux of CO2 in order to detect potential leakage during injection and post-injection monitoring. In November 2009 diffuse flux measurements of CO2 using an accumulation chamber were made in the area selected by CIUDEN for geological storage, located in Hontomin province of Burgos (Spain). This paper presents the tests carried out in order to establish the optimum sampling methodology and the geostatistical analyses performed to determine the range, with which future field campaigns will be planned.

República Federativa Evangélica: uma análise de gênero sobre a laicidade no Brasil a partir da atuação dos/as parlamentares evangélicos/as no Congresso Nacional no exerc��cio da 54ª Legislatura São Bernardo do Campo

Essa pesquisa objetiva a análise da relação entre religião e política, em perspectiva de gênero considerando a atuação de parlamentares evangélicos/as na 54ª Legislatura (de 2011 a 2014) e a forma de intervenção desses atores no espaço político brasileiro quanto à promulgação de leis e ao desenvolvimento de políticas públicas que contemplem, dentre outras, a regulamentação do aborto, a criminalização da homofobia, a união estável entre pessoas do mesmo sexo e os desafios oriundos dessa posição para o Estado Brasileiro que se posiciona como laico. Ora, se laico remete à ideia de neutralidade estatal em matéria religiosa, legislar legitimado por determinados princ��pios fundamentados em doutrinas religiosas, pode sugerir a supressão da liberdade e da igualdade, o não reconhecimento da diversidade e da pluralidade e a ausência de limites entre os interesses públicos / coletivos e privados / particulares. Os procedimentos metodológicos para o desenvolvimento dessa pesquisa fundamentam-se na análise e interpretação bibliográfica visando estabelecer a relação entre religião e política, a conceituação, qualificação e tipificação do fenômeno da laicidade; levantamento documental; análise dos discursos de parlamentares evangélicos/as divulgados pela mídia, proferidos no plenário e adotados para embasar projetos de leis; pesquisa qualitativa com a realização de entrevistas e observações das posturas públicas adotadas pelos/as parlamentares integrantes da Frente Parlamentar Evangélica - FPE. Porquanto, os postulados das Ciências da Religião devidamente correlacionados com a interpretação do conjunto de dados obtidos no campo de pesquisa podem identificar o lugar do religioso na sociedade de forma interativa com as interfaces da laicidade visando aprofundar a compreensão sobre a democracia, sobre o lugar da religião nas sociedades contemporâneas e sobre os direitos difusos, coletivos e individuais das pessoas.

Acceleration and Deflection Analysis for Class C Edge Protection Systems in Construction Work

The requirements for edge protection systems on most sloped work surfaces (class C, according to EN 13374-2013 code) in construction works are studied in this paper. Maximum deceleration suffered by a falling body and maximum deflection of the protection system were analyzed through finite-element models and confirmed through full-scale experiments. The aim of this work is to determine which value for deflection system entails a safe deceleration for the human body. This value is compared with the requirements given by the current version of EN 13374-2013. An additional series of experiments were done to determine the acceleration linked to minimum deflection required by code (200 mm) during the retention process. According to the obtained results, a modification of this value is recommended. Additionally, a simple design formula for this falling protection system is proposed as a quick tool for the initial steps of design.

Precompetitive data sharing as a catalyst to address unmet needs in Parkinson's disease

Parkinson's disease is a complex heterogeneous disorder with urgent need for disease-modifying therapies. Progress in successful therapeutic approaches for PD will require an unprecedented level of collaboration. At a workshop hosted by Parkinson's UK and co-organized by Critical Path Institute's (C-Path) Coalition Against Major Diseases (CAMD) Consortiums, investigators from industry, academia, government and regulatory agencies agreed on the need for sharing of data to enable future success. Government agencies included EMA, FDA, NINDS/NIH and IMI (Innovative Medicines Initiative). Emerging discoveries in new biomarkers and genetic endophenotypes are contributing to our understanding of the underlying pathophysiology of PD. In parallel there is growing recognition that early intervention will be key for successful treatments aimed at disease modification. At present, there is a lack of a comprehensive understanding of disease progression and the many factors that contribute to disease progression heterogeneity. Novel therapeutic targets and trial designs that incorporate existing and new biomarkers to evaluate drug effects independently and in combination are required. The integration of robust clinical data sets is viewed as a powerful approach to hasten medical discovery and therapies, as is being realized across diverse disease conditions employing big data analytics for healthcare. The application of lessons learned from parallel efforts is critical to identify barriers and enable a viable path forward. A roadmap is presented for a regulatory, academic, industry and advocacy driven integrated initiative that aims to facilitate and streamline new drug trials and registrations in Parkinson's disease.
