A new transition-metal-containing Zintl compound, Eu10Mn6Sb13, was prepared by a high-temperature Sn-flux synthesis. The structure was determined by single-crystal X-ray diffraction. Eu10Mn6Sb13 crystallizes in the monoclinic space group C2/m with a = 15.1791(6) Angstrom, b = 19.1919(7) Angstrom, c = 12.2679(4) Angstrom, beta = 108.078(1)degrees, Z = 4 (R1 = 0.0410, wR2 = 0.0920), and T = 90(2) K. The structure of Eu10Mn6Sb13 is composed of double layers of Mn-centered tetrahedra separated by Eu2+ cations. The double layers are composed of edge- and corner-sharing Mn-centered tetrahedra which form cavities occupied by Eu2+ cations and [Sb-2](4-) dumbbells. Linear [Sb-3](5-) trimers bridging two tetrahedra across the cavity are also present. Bulk susceptibility data indicate paramagnetic behavior with a ferromagnetic component present below 60 K. Temperature-dependent electrical resistivity measurements show semiconducting behavior above 60 K (E-a = 0.115(2) eV), a large and unusually sharp maximum in the resistivity at similar to40 K, and metallic behavior below 40 K. Eu-151 Mossbauer spectra confirm that the europium is divalent with an average isomer shift of -11.2(1) mm/s at 100 K; the spectra obtained below 40 K reveal magnetic ordering of six of the seven europium sublattices and, at 4.2 K, complete ordering of the seven europium sublattices.

BACKGROUND: The corneofungimetry bioassay was designed as a unique model predicting the efficacy of topical and oral antifungals in dermatomycoses. OBJECTIVE: In this 2-step study performed in two groups of 15 volunteers, corneofungimetry was used to compare the effect of 5-day b.i.d. treatments with 2% ketoconazole and 1% terbinafine creams. METHODS: The bioassay was performed using 10 isolates of each of the 3 fungi Trichophyton rubrum, T. mentagrophytes var. interdigitale and Candida albicans put to grow on human stratum corneum. Controls were stratum corneum either untreated or enriched in propylene glycol contained in an unmedicated vehicle. Quantitative assessments were made using both Euclidean and fractal geometry parameters. RESULTS: In comparison with untreated stratum corneum, the fungitoxic activity of the 2% ketoconazole and 1% terbinafine formulations was obvious and similar against dermatophytes. By contrast, 2% ketoconazole was significantly more active against C. albicans than 1% terbinafine. The propylene-glycol-containing vehicle did not exhibit a significant effect upon the dermatophyte growth. Positive linear correlations were yielded between the extent area and the fractal dimension D of dermatophyte mycelia. By contrast, D appeared unrelated to the relative area of dermatophyte growth compared to controls. CONCLUSION: The combination of Euclidean and fractal analyses improves the information provided by the corneofungimetry bioassay. Creams containing 2% ketoconazole and 1% terbinafine appear equally effective against dermatophytes while the former is more potent against Candida albicans. [less ▲]

Eugène Catalan est né il y a exactement 200 ans ! Ses travaux mathématiques sont remarquables, tant par leur quantité (on dénombre environ 380 articles et 70 livres ou mémoires) que du point de vue de leur qualité et de leur variété. En effet, son nom est encore aujourd'hui associé à de nombreux domaines des mathématiques. Citons notamment diverses conjectures fameuses sur les nombres ou équations, l'étude de nombres éponymes en combinatoire, l'introduction des polyèdres semi-réguliers ou des surfaces minimales en géométrie, le calcul d'intégrales multiples ou encore de séries en analyse. A l'occasion de cet anniversaire, nous mettons en évidence quelques éléments de sa biographie. [less ▲]

The Solar Orbiter mission will explore the connection between the Sun and its heliosphere, taking advantage of an orbit approaching the Sun at 0.28 AU. As part of this mission, the Extreme Ultraviolet Imager (EUI) will provide full-sun and high-resolution image sequences of the solar atmosphere at selected spectral emission lines in the extreme and vacuum ultraviolet. To achieve the required scientific performances under the challenging constraints of the Solar Orbiter mission it was required to further develop existing technologies. As part of this development, and of its maturation of technology readiness, a set of breadboard and prototypes of critical subsystems have thus been realized to improve the overall instrument design. The EUI instrument architecture, its major components and sub-systems are described with their driving constraints and the expected performances based on the breadboard and prototype results. The instrument verification and qualification plan will also be discussed. We present the thermal and mechanical model validation, the instrument test campaign with the structural-thermal model (STM), followed by the other instrument models in advance of the flight instrument manufacturing and AIT campaign.
