    La Revue d’Alsace a choisi d’accueillir un ouvrage portant sur le football. Cette innovation mĂ©rite un mot d’explication car les lecteurs ne savent pas tous que depuis plus d’une dĂ©cennie, l’histoire des sports et du football a fait son entrĂ©e comme territoire lĂ©gitime dans l’enseignement et la recherche Ă  l’UniversitĂ©. Cette histoire-lĂ  s’intĂ©resse au football parce qu’il s’agit d’un phĂ©nomĂšne social, Ă©conomique, culturel et politique de premiĂšre importance du XXe siĂšcle. Son traitement ne s..

    DĂ©jĂ  auteur d’études sur les problĂšmes de l’immĂ©diat aprĂšs-guerre en Alsace, Jean-Laurent Vonau prĂ©sente ici une courte synthĂšse de l’histoire de la rĂ©gion durant la guerre. Tout au long du rĂ©cit, l’empreinte du juriste est prĂ©sente. On retrouve aussi toutes les structures du systĂšme, toutes les mesures, une histoire complĂšte de la nazification au final. Le dĂ©veloppement mĂ©riterait parfois un autre titre qui serait l’Alsace durant le nazisme, mais Wagner est nĂ©anmoins suffisamment prĂ©sent. Qu..

    L’ouvrage comporte deux parties distinctes. La premiĂšre est une BD qui raconte le sĂ©jour de vacances (1942) d’un jeune strasbourgeois chez son oncle et sa tante qui exploitent une ferme proche du camp de concentration de Natzweiller-le Struthof. La seconde partie rĂ©sume le fonctionnement du systĂšme concentrationnaire nazi et plus particuliĂšrement du Struthof ; elle est rĂ©digĂ©e par Robert Steegmann, l’auteur de publications sur le camp. La BD retrace le voyage de Raymond et de son pĂšre Ă  Rotha..

    Common Motifs in the Response of Cereal Primary Metabolism to Fungal Pathogens are not Based on Similar Transcriptional Reprogramming

    During compatible interactions with their host plants, biotrophic plant–pathogens subvert host metabolism to ensure the sustained provision of nutrient assimilates by the colonized host cells. To investigate, whether common motifs can be revealed in the response of primary carbon and nitrogen metabolism toward colonization with biotrophic fungi in cereal leaves, we have conducted a combined metabolome and transcriptome study of three quite divergent pathosystems, the barley powdery mildew fungus (Blumeria graminis f.sp. hordei), the corn smut fungus Ustilago maydis, and the maize anthracnose fungus Colletotrichum graminicola, the latter being a hemibiotroph that only exhibits an initial biotrophic phase during its establishment. Based on the analysis of 42 water-soluble metabolites, we were able to separate early biotrophic from late biotrophic interactions by hierarchical cluster analysis and principal component analysis, irrespective of the plant host. Interestingly, the corresponding transcriptome dataset could not discriminate between these stages of biotrophy, irrespective, of whether transcript data for genes of central metabolism or the entire transcriptome dataset was used. Strong differences in the transcriptional regulation of photosynthesis, glycolysis, the TCA cycle, lipid biosynthesis, and cell wall metabolism were observed between the pathosystems. However, increased contents of Gln, Asn, and glucose as well as diminished contents of PEP and 3-PGA were common to early post-penetration stages of all interactions. On the transcriptional level, genes of the TCA cycle, nucleotide energy metabolism and amino acid biosynthesis exhibited consistent trends among the compared biotrophic interactions, identifying the requirement for metabolic energy and the rearrangement of amino acid pools as common transcriptional motifs during early biotrophy. Both metabolome and transcript data were employed to generate models of leaf primary metabolism during early biotrophy for the three investigated interactions

    Die Grundeigenschaften positiver MĂŒonen (positive Elementarladung, Spin 1/2, MassenverhĂ€ltnis MĂŒon/Proton ≈ 1/9, großes magnetisches Moment, paritĂ€tsverletzender Zerfall in ein Positron und zwei Neutrinos) und ihre VerfĂŒgbarkeit in Form intensiver spinpolarisierter Strahlen in "Mesonen-Fabriken" gestatten es, mit Hilfe der μ+SR ("MĂŒon-Spin-Rotation")-Methode die Wechselwirkung der MĂŒonen mit Magnetfeldern in Metallen zu studieren. In dieser Arbeit geben wir einen kurzen Überblick ĂŒber die μ+SR-Methode und ihre Anwendung auf das Studium der Lokalisierung und Diffusion von MĂŒonen in Metallen fĂŒr den Fall der dipolaren Wechselwirkung mit den magnetischen Momenten der Kerne. Die ZusammenhĂ€nge zwischen den gemessenen Relaxationsraten und der MĂŒonenbeweglichkeit und dem Einfang und Entweichen an Verunreinigungen werden dargestellt und anhand von Messungen an hochreinen Be-, Nb- und Ta-Einkristallen veranschaulicht

    LSST: from Science Drivers to Reference Design and Anticipated Data Products

    (Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, and LSST will have unique survey capability in the faint time domain. The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the Solar System, exploring the transient optical sky, and mapping the Milky Way. LSST will be a wide-field ground-based system sited at Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m effective) primary mirror, a 9.6 deg2^2 field of view, and a 3.2 Gigapixel camera. The standard observing sequence will consist of pairs of 15-second exposures in a given field, with two such visits in each pointing in a given night. With these repeats, the LSST system is capable of imaging about 10,000 square degrees of sky in a single filter in three nights. The typical 5σ\sigma point-source depth in a single visit in rr will be ∌24.5\sim 24.5 (AB). The project is in the construction phase and will begin regular survey operations by 2022. The survey area will be contained within 30,000 deg2^2 with ÎŽ<+34.5∘\delta<+34.5^\circ, and will be imaged multiple times in six bands, ugrizyugrizy, covering the wavelength range 320--1050 nm. About 90\% of the observing time will be devoted to a deep-wide-fast survey mode which will uniformly observe a 18,000 deg2^2 region about 800 times (summed over all six bands) during the anticipated 10 years of operations, and yield a coadded map to r∌27.5r\sim27.5. The remaining 10\% of the observing time will be allocated to projects such as a Very Deep and Fast time domain survey. The goal is to make LSST data products, including a relational database of about 32 trillion observations of 40 billion objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures available from https://www.lsst.org/overvie
