Precise magnetotransport studies of heat and charge carriers in polycrystalline MgB2 show that magnetic fields up to 8 T remarkably influence electrical resistivity, thermoelectric power and thermal conductivity. The superconducting transition temperature shifts from 39 K to 19 K at 8 T as observed on electric signals. The temperature transition width is weakly broadened. Electron and phonon contributions to the thermal conductivity are separated and discussed. The Debye temperature calculated from a phonon drag thermoelectric power component is inconsistent with values derived through other effects. [less ▲]

Behavioural activation repeatedly induced by a stimulant in rodents can persist in the absence of the drug if the animals are tested in the context where the drug was previously given, a phenomenon often explained in terms of Pavlovian conditioning. The aim of this study was to verify whether the amplitude of the putative CR (the drug-like activity) increases with the number of the US-CS associations (the number of drug-context pairings), one of the most representative rules of Pavlovian conditioning. The effect of the number of trials on the speed of extinction was also considered. C57BL/6J mice received 3, 6 or 12 once-daily injections of either saline or 12 mg/kg (-)-cocaine hydrochloride (s.c.) in the same test context, a photocell activity-box in which they were tested for 60 min after every injection. Other groups received the same treatments outside of the test context (being placed in a novel cage tub after each injection). Twenty-four hours after the last treatment session, all mice were challenged with saline in the test context (test for conditioned activity), extinction sessions taking place on the three subsequent days. Sensitisation to the locomotor-activating effect of cocaine developed only amongst the animals injected 6 or 12 times, the magnitude of the last sensitised response being comparable for these two injections regimen. On saline challenge, only the animals that had received 6 or 12 cocaine injections showed significant conditioned activity (CR), with the greatest response occurring following 12 injections. The 6-trial group reached the level of non-significance after fewer extinction sessions than the 12-trial group; however, the rates of extinction did not differ (comparable regression coefficients and quasi-parallel curves). These results suggest that the amplitude of the CR (cocaine-like stimulation after saline), and perhaps less convincingly the duration of extinction, are functions of the number of the US-CS (cocaine-context) pairings, supporting the Pavlovian nature of post-sensitisation placebo drug-like effects.

La0.6Y0.1Ca0.3MnO3, an ABO(3) perovskite manganite oxide, exhibits a nontrivial behavior in the vicinity of the sharp peak found in the resistivity rho as a function of temperature T in zero magnetic field. The various features seen on drho/dT are discussed in terms of competing phase transitions. They are related to the Mn-O-Mn bond environment depending on the content of the A crystallographic site. A Ginzburg-Landau type theory is presented for incorporating concurrent phase transitions. The specific heat C of such a compound is also examined from 50 to 200 K. A log-log analysis indicates different regimes. In the low temperature conducting ferromagnetic phase, a collective magnon signature (Csimilar or equal toT(3/2)) is found as for what are called magnon-polaron excitations. A Csimilar or equal toT(2/3) law is found at high temperature and discussed in terms of the fractal dimension of the conducting network of the weakly conducting (so-called insulating) phase and an Orbach estimate of the excitation spectral behaviors. The need of considering both independent spin scattering and collective spin scattering is thus emphasized. The report indicates a remarkable agreement for the Fisher-Langer formula, i.e., Csimilar todrho/dT at second order phase transitions. Within the Attfield model, we find an inverse square root relationship between the critical temperature(s) and the total local Mn-O-Mn strain. [less ▲]

La collection de manuscrits arabes (et en écriture arabe) de la Bibliothèque Générale de l'Université de Liège est exceptionnelle... et trop peu connue. Un manuscrit particulier est ici présenté. Il s'agit d'une copie du XVIe siècle (de notre ère) du Kitāb al-Faraj baʿd aš-Šidda, ouvrage littéraire de l'irakien at-Tanuḫī (327-384 de l'Hégire/939-994 apr. J.C.). Le manuscrit a fait l'objet d'une analyse codicologique et paléographique détaillée, couplée à une analyse philologique du texte, comprenant notamment sa collation avec l'édition critique généralement utilisée. Cette étude a permis de mettre en avant les particularités du manuscrit en tant qu'objet et en tant que texte et de le placer dans la tradition manuscrite maghrébine du XVIe siècle. [less ▲]

In1948, the Belgian painter René Magritte exhibited in an art gallery in Paris paintings and gouaches that were met with acrimony. Leaders of surreal- ism, usually fond of provocations, did not accepted this one. Many readings of this event have been proposed, starting from Magritte himself. The variety or even the divergence of such readings, however, suggests the need to interpret these works from a broader perspective. Starting from the aesthetic principles established by Hegel, the present essay seeks to show how Magritte endeav- oured to “release painting” from both personal and social censorship, which is constitutive of the very art of painting.

The Solar Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory will characterize the dynamical evolution of the solar plasma from the chromosphere to the corona, and will follow the connection of plasma dynamics with magnetic activity throughout the solar atmosphere. The AIA consists of 7 high-resolution imaging telescopes in the following spectral bandpasses: 1215Å. Ly-a, 304 Å He II, 629 Å OV, 465 Å Ne VII, 195 Å Fe XII (includes Fe XXIV), 284 Å Fe XV, and 335 Å Fe XVI. The telescopes are grouped by instrumental approach: the MAGRITTE Filtergraphs (R. MAGRITTE, famous 20th Century Belgian Surrealistic Artist), five multilayer EUV channels with bandpasses ranging from 195 to 1216 Å, and the SPECTRE Spectroheliograph with one soft-EUV channel at OV 629 Å. They will be simultaneously operated with a 10-second imaging cadence. These two instruments, the electronic boxes and two redundant Guide Telescopes (GT) constitute the AIA suite. They will be mounted and coaligned on a dedicated common optical bench. The GTs will provide pointing jitter information to the whole SHARPP assembly. This paper presents the selected technologies, the different challenges, the trade-offs to be made in phase A, and the model philosophy. From a scientific viewpoint, the unique combination high temporal and spatial resolutions with the simultaneous multi-channel capability will allow MAGRITTE / SPECTRE to explore new domains in the dynamics of the solar atmosphere, in particular the fast small-scale phenomena. We show how the spectral channels of the different instruments were derived to fulfill the AIA scientific objectives, and we outline how this imager array will address key science issues, like the transition region and coronal waves or flare precursors, in coordination with other SDO experiments. We finally describe the real-time solar monitoring products that will be made available for space-weather forecasting applications. [less ▲]

Tout le monde aura entendu ou lu dans la presse la façon dont l'actuel président français, initiateur d'une révolution conservatrice sans précédent en France, fustige l'esprit de 68. L'on pourrait s'amuser d'un tel positionnement campé par un politicien qui, par ailleurs, n'a guère rechigné à afficher le comportement amoureux léger qu'on lui connaît et que n'auraient pas désavoués les étudiant(e)s de mai lorsqu'ils étaient sur les barricades, aux prises avec le conservatisme français en matière de moeurs. Mais mon propos sera ici d'une autre nature, bien qu'il s'inscrive dans un étonnement similaire face aux diatribes de Nicolas Sarkozy. En effet, il est probablement un second élément qui rappelle ce dernier au souvenir de cette révolution dont il veut « liquider l'héritage » : la pensée économique « libertarienne », née, pour sa déclinaison française, de l'improbable union entre l'esprit frondeur et libertaire de 68 et l'économie de marché [less ▲]

This report presents the two phases of the SERIES project TA5 EQUALS MAID. The purpose of the first phase is to elaborate a better understanding of the seismic behaviour of masonry walls in dynamic conditions and to investigate the consequences of the use of rubber elements aiming at improving the acoustic performance of buildings. The tested specimens are four simple unreinforced clay masonry walls, two of them including rubber soundproofing devices at the bottom and top of the wall . Results demonstrate a significant rocking behaviour and comparisons between the four specimens provide useful information about the influence of the aspect ratio of the walls and of the presence of rubber devices. The second phase has a double purpose. The first objective is to characterize the frame effects in masonry shear walls coupled by horizontal elements (concrete lintel and slab). The second objective is to study the influence of the presence of walls perpendicular to the earthquake action. The second test series consists thus in two specimens made of two walls with horizontal cross-section respectively in T and L shape coupled at their top by a lintel and a slab. Different loading conditions are also considered, with a slab resting on entire walls or only on part of them. [less ▲]
