Vonau (Jean-Laurent), Le Gauleiter Wagner. Le bourreau de lâAlsace
DĂ©jĂ auteur dâĂ©tudes sur les problĂšmes de lâimmĂ©diat aprĂšs-guerre en Alsace, Jean-Laurent Vonau prĂ©sente ici une courte synthĂšse de lâhistoire de la rĂ©gion durant la guerre. Tout au long du rĂ©cit, lâempreinte 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 lâAlsace durant le nazisme, mais Wagner est nĂ©anmoins suffisamment prĂ©sent. Qu..
Wagner (Vincent), Seiter (Roger), Un été en enfer, Steegmann (Robert), Encart
Lâouvrage comporte deux parties distinctes. La premiĂšre est une BD qui raconte le sĂ©jour de vacances (1942) dâun 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, lâauteur 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 plantâpathogens 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
Localization and diffusion of positive muons in metals
Die Grundeigenschaften positiver MĂŒonen (positive Elementarladung, Spin 1/2, MassenverhĂ€ltnis MĂŒon/Proton ≈ 1/9, groĂes 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 Ăberblick 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 deg 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 5
point-source depth in a single visit in will be (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 deg with
, and will be imaged multiple times in six bands, ,
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 deg region about 800 times (summed over all six bands) during the
anticipated 10 years of operations, and yield a coadded map to . 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
