Some structural and hydrodynamic properties of RCM-NCX-1116, a Ni-Cr metallic foam packing manufactured by Recemat International B.V (The Netherlands) are investigated using X-ray radiography and X-ray micro-tomography. Local values of porosity and pore diameters are measured on a foam sample 3D image obtained with a Skyscan-1172 high-resolution desk-top micro-CT system operated at 100 kV. Structural parameters computed on tomography images agree well with manufacturer data. Hydrodynamic tests are performed in a flat rectangular column packed with a sheet of metallic foam packing. Measurements are realized with a single-phase flow of liquid as well as with a counter-current flow of gas and liquid. Dynamic and static liquid holdup distributions and liquid radial spreading coefficient are measured on 2D radiographic images of the bed obtained with the high energy large scale ULG 420 kV scanner operated in the radiographic mode at 420 kV. Pressure drop measurements are successfully compared to experimental results reported in literature, as well as to the literature model predictions and to values computed using an in-house Lattice Boltzmann CFD simulation code.

Circulation des biens et des personnes au Moyen Age : l’étude des reliques comme objets historiques permet des recoupements extraordinaires, souvent insoupçonnés et très utiles, notamment pour l’histoire de l’art. Stavelot-Malmedy a réformé Montier-en-Der en Champagne au IXe siècle. Curieusement la liste des confraternités de l’abbaye de Stavelot-Malmedy (Cfr Commission Royale d’Histoire) ne mentionne pas Montier. C’est ailleurs qu’il faut rechercher les liens avec l’abbaye champenoise. Trois découvertes importantes font l’objet de cet article : les vestiges d’un important reliquaire mosan du Der, conservé aujourd’hui dans une collection privée anglaise, une mention supplémentaire d’Erlebald, frère de l’abbé Wibald, à ajouter au précédent inventaire (Le Moyen Age) et toujours l'orfèvre Godefroid de Huy ( Cfr Cahiers de Civilisation Médiévale). L’article aboutit à la reconstitution d’un important trésor bénédictin. [less ▲]

We report measurements of the isotope shifts of the 3d64s2 a 5D4 − 3d64s4p z 5Fo 5 Fe I resonance line at 372 nm between all four stable isotopes 54Fe, 56Fe, 57Fe and 58Fe, as well as the complete hyperfine structure of that line for 57Fe, the only stable isotope having a non-zero nuclear spin. The field and specific mass shift coefficients of the transition have been derived from the data, as well as the experimental value for the hyperfine structure magnetic dipole coupling constant A of the excited state of the transition in 57Fe : A(3d64s4p z 5Fo 5 ) = 81.69(86) MHz. The measurements were carried out by means of high-resolution Doppler-free laser saturated absorption spectroscopy in a Fe-Ar hollow cathode discharge cell using both natural and enriched iron samples. The measured isotope shifts and hyperfine constants are reported with uncertainties at the percent level. [less ▲]

BACKGROUND: To evaluate changes in pulse pressure (PP) and markers of cardiovascular autonomic neuropathy (CAN) according to duration of type 1 diabetes mellitus (T1DM). METHODS: This cross-sectional controlled study evaluated 159 diabetic patients during a 3-min posture test (standing-squatting-standing) with continuous measurement of systolic (SBP), diastolic (DBP) and mean (MBP) blood pressure by a Finapres device. Arterial stiffness was indirectly assessed by PP and the slope of PP as a function of MBP calculated during the whole 3-min test. CAN was assessed by the expiration/inspiration pulse interval ratio (E/I R-R ratio) during deep breathing and by three indices measured during the squatting test. Patients were divided into four groups according to diabetes duration (<10 years, 11-20 years, 21-30 years and > 30 years from group 1 to group 4, respectively) and compared with age-matched non-diabetic subjects. RESULTS: PP progressively increased (p < 0.0001) and PP/MBP decreased (p < 0.0005) according to T1DM duration, whereas these parameters remained almost unchanged in age-matched control subjects. E/I ratio (p < 0.0001) and baroreflex gain (p < 0.0005) progressively decreased with T1DM duration. The parasympathetic index (squatting test vagal ratio-SqTv) significantly increased (p < 0.0001), whereas the sympathetic index (squatting test sympathetic ratio-SqTs) only tended to decrease (p = 0.12) according to diabetes duration. No such changes in CAN indices were observed in the non-diabetic population. CONCLUSIONS: PP increased according to T1DM duration in an age range where PP remained almost stable in controls, in agreement with accelerated arterial stiffening due to chronic hyperglycaemia. The baroreflex gain decreased and other indices of CAN also deteriorated with diabetes duration, more so indices reflecting parasympathetic rather than sympathetic dysfunction. [less ▲]

Nonlinear optical susceptibilities and Raman scattering spectra of the ferroelectric phases of BaTiO3 and PbTiO3 are computed using a first-principles approach based on density functional theory and taking advantage of a recent implementation based on the nonlinear response formalism and the 2n + 1 theorem. These two prototypical ferroelectric compounds were chosen to demonstrate the accuracy of the Raman calculation based both on their complexity and their technological importance. The computation of the Raman scattering intensities has been performed not only for the transverse optical modes, but also for the longitudinal optical ones. The agreement between the measured and computed Raman spectra of these prototypical ferroelectrics is remarkable for both the frequency position and the intensity of Raman lines. This agreement presently demonstrates the state-of-the-art in the computation of Raman responses on one of the most complex systems, ferroelectrics, and constitutes a step forward in the reliable prediction of their electro-optical responses.

At the instigation of the Musée du Louvre’s Department of Egyptian Antiquities, an intensive programme to study black bronze has been carried out at the Centre de Recherche et de Restauration des Muse´es de France. Systematic research has been undertaken on the museum’s collection to identify objects that might have an intentional black patina. The same experimental protocol has been applied to all the objects, alllowing this study to be one of the most important coherent investigation on this type of bronze decoration. It involves the use of non-invasive analytical methods in order to obtain the maximum amount of information possible about the chemical nature and structure of the surface layer. The protocol makes it possible to compare objects and to propose an interpretation of how this decorative technique evolved during the Egyptian period. Based on previous stylistic investigations (by J. Cooney, 1966) and personal observation, sixteen objects dating from the Middle Kingdom to the Late Period were selected. Thanks to elemental analyses, twelve of them were identified as being intentionally patinated. Only ten of these could be described as hmty-km, because the base patinated alloy contains small amounts of gold and/or silver and the black patina is made up mainly of cuprous oxide Cu2O (cuprite). Among the four other objects, one patina is very close to the black bronze patina, but contains neither gold nor silver. Three other pieces have an unusual patina. A lack of other comparable examples makes it very difficult to determine whether the patinas are of ancient origin. [less ▲]
