Vers une théorie antivitale, antihoméostatique et antiadaptative de la vie chez Freud: Le travail du concept de pulsion

Indexación: Scopus.Situado en el examen del concepto de pulsión [Trieb], piedra angular de la arquitectura teórica del psicoanálisis, el presente artículo pretende destacar dos grandes líneas de análisis: en primer lugar, mostrar el conjunto de los aspectos filosóficos y ontológicos que el concepto moviliza en su reflexión sobre los dinamismos y los sentidos de la vida humana; y, en segundo lugar, evidenciar la subversión que el concepto establece en el seno de los postulados mayores del pensamiento científico, filosófico y médico del siglo XIX, al introducir una concepción general de la vida como un acontecer esencialmente antivital, antihomeostático y antiadaptativo, en el cual las tendencias a la muerte, a la degradación y a la inercia forman parte de su patrimonio más arcaico e inmanente.Placé dans l’examen du concept de pulsion [Trieb], soubassement angulaire de l’architecture théorique de la psychanalyse, cet article prétend souligner deux grandes lignes d’analyse: premièrement, montrer l’ensemble des aspects philosophiques et ontologiques que le concept mobilise dans sa réflexion sur les dynamismes et les sens de la vie humaine ; et, deuxièmement, avérer la subversion que le concept établit au sein des postulats majeures de la pensée scientifique, philosophique et médicale du XIXe siècle, de la sorte d’y introduire une conception générale sur la vie en tant que avènement essentiellement antivital, antihoméostatique et antiadaptatif, dans lequel les tendances envers la mort, la dégradation et l’inertie font partie de son patrimoine le plus archaïque e immanentfile:///C:/Users/paula.pardo/Downloads/246-642-1-PB.pd

Fingering Instabilities on Reaction Fronts in the CO Oxidation Reaction on Pt(100)

Fingering instabilities arising from local perturbations to planar reaction fronts in the CO oxidation reaction on Pt(100) are presented. CO oxidation represents a heterogeneous nonlinear system with the necessary kinetic and diffusive transport properties to support the development of fingered wave fronts. External forcing was utilized to create CO wave fronts on an otherwise monostable, O-covered surface, which, upon destabilization, gave rise to fingers of adsorbed CO extending into the O adlayer ahead of the reaction front. Finger spreading and tip-splitting were observed as the finger pattern evolved towards an intrinsic wavelength, independent of the length of the reaction front, calculated to be approximately 40 μm. Our data also show the presence of a shielding process, where at wavelengths less than twice the observed intrinsic value, additional fingers were created on the reaction front through a tip-splitting bifurcation of an existing finger. At wavelengths greater than twice the intrinsic value, additional fingers formed in the troughs between adjacent fingers, apparently unaffected by the presence of the larger surrounding fingers

Panorama geopolítico del mundo actual. Medios de comunicación y cambios en la escena política: El ascenso de Podemos

El impacto de los nuevas formas y técnicas de comunicación política en las sociedades afectadas por la crisis ha provocado cambios en la escena política. En algunos países el ascenso de nuevos partidos políticos ha sido posible por sus aciertos al construir sus mensajes y objetivos, pero también por el apoyo de algunos medios de comunicación de masas y por el uso adecuado de las nuevas tecnologías. El caso de Podemos en España es un buen ejemplo de esta combinación de factores.The impact of new forms and techniques of political communication in societies affected by the crisis has caused changes in the political scene. In some countries the rise of new political parties has been made possible by their success in building their messages and objectives, but also by the support of some mass media and the proper use of new technologies. The case of We in Spain is a good example of this combination of factor

Interaction soot-SO2. Experimental and kinetic analysis

This study aims to evaluate the capability of SO2 to interact with soot and to determine the kinetics of this reaction under conditions of interest for combustion. The conditions of the soot reactivity experiments were: 1% SO2 with nitrogen to balance, around 10 mg of soot, and different reaction temperatures for each run: 1275, 1325, 1375, 1425, and 1475 K. Results demonstrate that SO2 does interact with soot. The evaluation of the soot reactivity has been based on the calculation of the time for the complete conversion of carbon through the employment of the Shrinking Core Model equations for decreasing size particle with chemical reaction control. The reactivity of soot with SO2 increased by a factor of about 3 when increasing the reaction temperature of the test from 1275 K to 1475 K. Kinetics in terms of Arrhenius parameters showed that the activation energy of the interaction of soot with SO2 was around 82 kJ/mol
