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 MAGRITTE telescopes are part of the SHARPP instrument suite, part of the Solar Dynamics Observatory (SDO), a NASA spacecraft to be launched in a geostationnary orbit in 2007. The MAGRITTE instrument package will provide high resolution images of the solar corona at high temporal frequency simultaneously in 5 EUV and in Ly-alpha narrow bandpasses. The 1.4 R[SUB]0[/SUB] MAGRITTE common field of view complements the other SHARPP instruments, as well as its spectral coverage with 6 narrow bandpasses located within the 19.5 to 120 nm interval. The key challenges of the MAGRITTE instrument are a high angular resolution (0.66 arcsec/pixel) with a high responsivity (exposure times smaller than 8 sec), combined with restricted spacecraft resources. The design of MAGRITTE is based on a high performance off-axis Ritchey-Chretien optical system combined with a large detector (4 K x 4 K, 12 µm pixel). The tight pointing stability performance of 1.2 arcsec over the image exposure time requires an active image motion control, using pointing information of a Guide Telescope, to compensate low frequency boresight variations produced by spacecraft jitter. The thermomechanical design and the mirror polishing are highly critical issues in the instrument design. This paper presents the MAGRITTE design concept with the expected performances based on a realistic error budget. The mirror polishing concept and performances are discussed. [less ▲]

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 ▲]

The reaction between a reducing sugar and an amino group and their subsequent interactions is known as the Maillard reaction. This reaction is considered as the most important reaction in food chemistry. It results in the formation of odour, aroma and pigments which are characteristic of baked, roasted and broiled foods. It is also responsible for the formation of carcinogens and could also reduce the nutritionnal value of foods by decreasing the concentration of essential amino-acids. In vivo, it is involved in collagen degradation. The Maillard reaction could be divided into three main stages. Early Maillard reaction corresponds to the reversible formation of a glycosylamine and its Amadori or Heyns rearrangements. The second stage corresponds to the degradation of the Amadori and Heyns rearrangement products. It leads to the formation of odorant heterocyclic compounds. The third stage corresponds to the polymerization of the reactive intermediates of the advanced reaction. It leads to melanoidins production. Temperature, reaction time, moisture content, concentration and nature of the reactants are important factors which influence the Maillard reaction. The Maillard reaction could be involved in many industrial applications. [less ▲]
