Deconstrucción de los relatos evangélicos de la pasión. Sobre el arraigo de la ficción en la Historia de las religiones

Las más elementales exigencias de rigor crítico e independencia siguen a menudo sin cumplirse hoy en día en la reconstrucción histórica de la figura del judío Yeshua ben Yosef (Jesús el galileo), en parte porque el carácter inconsistente de las fuentes evangélicas no es tomado en serio. El presente artículo analiza las incongruencias de los relatos de la pasión, muestra en ellos los indicios de un proceso de despolitización, y señala el carácter insostenible de varias afirmaciones clave de muchos historiadores contemporáneos sobre el predicador galileo.

The Approach to Daesh in Tunisia: From Bardo to Ben Gardane, aYear of Terror

Starting from a descriptive analysis of the main attacks by Daesh in Tunisia, this article examines the nature and evolution of the terrorist organization in this North African country. Thus, it examines the characteristics and vicissitudes of the attack on the Bardo Museum in March 2015, the attack on the Susa beach in June 2015, the bombing of the Presidential Guard in November 2015 and, finally, the military offensive against the town of Ben Gardane in March 2016. In addition, it presents some previous facts that are relevant in this research, such as the important presence of Tunisian foreign fighters in Syria or Libya, and, in particular, the threat of Daesh in Libya to the Tunisian State

Asymmetric hydrogen flame in a heated micro-channel: role of Darrieus-Landau and thermal-diffusive instabilities

Present work examines numerically the asymmetric behavior of hydrogen/air flame in a micro-channel subjected to a non-uniform wall temperature distribution. A high resolution (with cell size of 25 μm × 25 μm) of two-dimensional transient Navier–Stokes simulation is conducted in the low-Mach number formulation using detailed chemistry evolving 9 chemical species and 21 elementary reactions. Firstly, effects of hydrodynamic and diffusive-thermal instabilities are studied by performing the computations for different Lewis numbers. Then, the effects of preferential diffusion of heat and mass transfer on the asymmetric behavior of the hydrogen flame are analyzed for different inlet velocities and equivalence ratios. Results show that for the flames in micro-channels, interactions between thermal diffusion and molecular diffusion play major role in evolution of a symmetric flame into an asymmetric one. Furthermore, the role of Darrieus–Landau instability found to be minor. It is also found that in symmetric flames, the Lewis number decreases behind the flame front. This is related to the curvature of flame which leads to the inclination of thermal and mass fluxes. The mass diffusion vectors point toward the walls and the thermal diffusion vectors point toward the centerline. Asymmetric flame is observed when the length of flame front is about 1.1–1.15 times of the channel width.

Landau-Gutzwiller quasi-particles

We define Landau quasiparticles within the Gutzwiller variational theory and derive their dispersion relation for general multiband Hubbard models in the limit of large spatial dimensions D. Thereby we reproduce our previous calculations which were based on a phenomenological effective single-particle Hamiltonian. For the one-band Hubbard model we calculate the frst-order corrections in 1/D and find that the corrections to the quasiparticle dispersions are small in three dimensions. They may be largely absorbed in a rescaling of the total bandwidth, unless the system is close to half band filling. Therefore, the Gutzwiller theory in the limit of large dimensions provides quasiparticle bands which are suitable for a comparison with real, three-dimensional Fermi liquids.
