La manière dont sont formulées bien des exigences de "neutralité de l'Etat" dans le débat public est souvent ambiguë. Ces exigences, dans beaucoup de cas visent les citoyens ordinaires tout autant que l'Etat. Elles manquent de fondement normatif et elles ne correspondent pas toujours aux pratiques réelles (et consensuelles) au sein de nos sociétés. Elles semblent parfois taillées sur mesure pour la défense de ce que Jean Baubérot appelle "le communautarisme républicain" et que l'on pourrait baptiser, en Belgique "communautarisme laïque".

The presentation distinguises between two different concepts of secularism : political secularism and philsophical secularism. It shows that those two concepts foster two visions of the neutrality of the state : a more tolerant one which supposes that the Sate holds itself at an equal distance of any religious or non religious set of beliefs. And an more agressive one which supposes that the state take an official stance of suspicion against religious beliefs. [less ▲]

In infected cattle, bovine herpesvirus type 4 (BHV-4) induces an immune response with low neutralizing antibody levels or in the absence of such antibodies. For the study of this phenomenon, monoclonal antibodies (MAbs) raised against two BHV-4 glycoproteins identified previously (150K/120K/51K and 120K/16.5K) were used in neutralization tests. None of the MAbs except for MAb 16 could neutralize alone; pairs of MAbs against the 150K/120K/51K and 120K/16.5K glycoproteins were able to neutralize BHV-4 infectivity. MAbs involved in neutralization were used in competitive binding assays to identify epitopes relevant for BHV-4 neutralization. These MAbs showed a low avidity and a weak neutralizing activity, and they partially decreased BHV-4 attachment to cells. These results suggest that the BHV-4 glycoprotein domains involved in viral infectivity are poorly exposed to the immune system. [less ▲]

Models for Majorana neutrino masses can be classified according to the level in perturbation theory at which the effective dimension five operator LLHH is realized. The possibilities range from the tree-level up to the three-loop level realizations. We discuss some general aspects of this approach and speculate about a model independent classification of the possible cases. Among all the realizations, those in which the effective operator is induced by radiative corrections open the possibility for lepton number violation near -or at- the electroweak scale. We discuss some phenomenological aspects of two generic radiative realizations: the Babu-Zee model and supersymmetric models with bilinear R-parity violation. [less ▲]

The high-peaked BL Lac object Pks2155-304 shows high variability at multiwavelengths, i.e. from optical up to TeV energies. A giant flare of around 1 h at X-ray and TeV energies was observed in 2006 [1]. In this context, it is essential to understand the physical processes in terms of the primary spectrum and the radiation emitted, since high-energy emission can arise in both leptonic and hadronic processes. In this contribution, we investigate the possibility of neutrino production in photo-hadronic interactions. In particular, we predict a direct correlation between optical and TeV energies at sufficiently high optical radiation fields. We show that in the blazar Pks2155-304, the optical emission in the low-state is sufficient to lead to photo-hadronic interactions and therefore to the production of high-energy photons. [less ▲]

Inelastic neutron scattering measurements on Ba8Ga16Ge30 and Sr8Ga16Ge30 indicate the presence of soft local modes with Einstein oscillator energies of 4.9 +/- 0.1 and 4.4 +/- 0.1 meV, modes which are associated with the lowest "rattling" mode of the Ba(B) and Sr(B) guests, respectively. Nuclear inelastic scattering measurements on Eu8Ga16Ge30 yield Einstein oscillator energies of between 3.0 +/- 0.3 and 7.5 +/- 1.2 meV for the different modes of the Eu guests. Further, the resonant character of the measurements on Eu8Ga16Ge30 reveals, without question, that neither of the Eu guests exhibit any vibrational modes above 9 meV. [less ▲]

Sintered, textured and single crystal products of the layered misfit [Bi0.81CaO2](2)[CoO2](1.69) cobaltite have been successfully synthesized and characterized. Based on structure and texture models, the orientation distribution of the hot-forged sample was successfully analysed by neutron diffraction. The results gave a clear description of the fiber texture with c-axes of the plate-like grains aligned parallel to the hot-forging direction. In terms of transport properties, the decrease of the electrical resistivity according to the degree of alignment and crystallinity of the materials evidenced the important role of the texturation and the strong anisotropy existing in these misfit layered cobaltites.

Lyme disease is a pathology caused by members of the Borrelia burgdorferi sensu lato (s.l.) complex, most often by B. burgdorferi sensu stricto (s.s.). They are transmitted mainly by Ixodes ricinus ticks. After a few hours of infestation, neutrophils massively infiltrate the bite site. They can kill Borrelia via phagocytosis, oxidative burst and hydrolytic enzymes. However, factors in tick saliva promote propagation of the bacteria in the host even in the presence of a large number of neutrophils. Neutrophil extracellular trap (NET) consists in the extrusion of the neutrophil’s own DNA, forming traps that can retain and kill bacteria. The production of reactive oxygen species (ROS) is apparently associated with the onset of NEtosis. Here we describe NETs formation at the tick bite site in vivo in mice. We show that Borrelia burgdorferi s.s. spirochetes become trapped and killed by NETs in humans and that the bacteria do not seem to release significant nucleases to evade this process. Saliva from I. ricinus did not affect NET formation by human neutrophiles or it stability. However, it strongly decreased neutrophil ROS production, suggesting that a strong decrease of hydrogen peroxide does not affect NET formation. Finally, round bodies were observed trapped in NETs, some of them staining as live cells. This observation could help contribute to a better explanation of erythema migrans. [less ▲]
