Résumé : BACKGROUND: The objective of this study was to describe the diagnostic panorama of human transmissible spongiform encephalopathies across 11 countries. METHODS: From data collected for surveillance purposes, we describe annual proportions of deaths due to different human transmissible spongiform encephalopathies in eleven EUROCJD-consortium countries over the period 1993-2002, as well as variations in the use of diagnostic tests. Using logistic models we quantified international differences and changes across time. RESULTS: In general, pre-mortem use of diagnostic investigations increased with time. International differences in pathological confirmation of sporadic Creutzfeldt-Jakob disease, stable over time, were evident. Compared to their counterparts, some countries displayed remarkable patterns, such as: 1) the high proportion, increasing with time, of variant Creutzfeldt-Jakob disease in the United Kingdom, (OR 607.99 95% CI 84.72-4363.40), and France (OR 18.35, 95% CI 2.20-152.83); 2) high, decreasing proportions of iatrogenic Creutzfeldt-Jakob disease in France, (OR 5.81 95% CI 4.09-8.24), and the United Kingdom, (OR 1.54 95% CI 1.03-2.30); and, 3) high and stable ratios of genetic forms in Slovakia (OR 21.82 95% CI 12.42-38.33) and Italy (OR 2.12 95% CI 1.69-2.68). CONCLUSION: Considerable international variation in aetiological subtypes of human transmissible spongiform encephalopathies was evident over the observation period. With the exception of variant Creutzfeldt-Jakob disease and iatrogenic Creutzfeldt-Jakob disease in France and the United Kingdom, these differences persisted across time.

Résumé : We have tested and validated a non-destructive analysis method of multilayer structure, which combine X-ray emission spectroscopy and X-ray reflectometry at 0.154 and 1.33 nm. In this purpose, a series of Mo/Si and Mo/B4C/Si/B4C multilayers, deposited by magnetron sputtering, have been designed. The thickness of the Mo layer is 2 nm and that of the Si layers varies between 1 and 4 nm. The B4C layer thickness introduced at the Mo/Si and Si/Mo interfaces is 0.3 or 1 nm. It is shown that the reflectivity of the multilayers lowers with the decreasing silicon thickness. This is correlated to the diffuse character on the nanometer scale of the Mo/Si and Si/Mo interfaces as shown by secondary ion mass spectrometry, and the formation of silicides (MoSi2and Mo5Si3) at these interfaces as evidenced by X-ray emission spectroscopy. As expected, the introduction of B4C diffusion barriers considerably improves the reflectivity coefficient in the soft X-ray range, due to thinner and more abrupt interfaces.

Résumé : L-band (1-2 GHz) microwave radiometry is the most relevant remote sensing technique to monitor soil moisture over land surfaces at the global scale. A synthetic multi-angular brightness temperature data set over land surfaces was simulated at 1.4 GHz, at a half-degree resolution and at the global scale (Pellarin et al., 2003a). This data set was built in order to develop and validate methods to retrieve soil moisture for near-future 1.4 GHz space missions. Brightness temperatures were computed using a simple model (L-MEB, L-band Microwave Emission of the Biosphere) based on radiative transfer equations. The L-MEB model is the result of an extensive review of the current knowledge of the microwave emission of various land covers (herbaceous and woody vegetation, frozen and unfrozen bare soil, snow, etc.) at L-Band considering that the model should be simple enough to be compatible with the simulation of a half-degree resolution and global scale data set. This model was parameterized for simulating L-band observations (in the 1-2 GHz range) but the model equations remain valid in a low frequency range (about 1 to 10 GHz) and thus including the L-, C- and X-bands. The soil and vegetation characteristics needed to initialize the L-MEB model were derived from existing land cover maps. Continuous simulations from a land-surface scheme for 1987 and 1988 provided time series of the main variables driving the L-MEB model: soil temperature at the surface and at depth, surface soil moisture, proportion of frozen surface soil moisture, and snow cover characteristics (depth, density, grain size, liquid water content). The different components of the emission model are described in the following sections. These sections present the general formulation of TB for a composite pixel and the microwave emission modules for soil, vegetation-covered surfaces, open water, snow-covered surfaces and atmospheric effects.

Résumé : We study the structure of very thin liquid crystal films frustrated by antagonistic anchorings in the smectic phase. In a cylindrical geometry, the structure is dominated by the defects for film thicknesses smaller than 150 nm and the detailed topology of the defects cores can be revealed by x-ray diffraction. They appear to be split in half tube-shaped Rotating Grain Boundaries (RGB). We determine the RGB spatial extension and evaluate its energy per unit line. Both are significantly larger than the ones usually proposed in the literature
