Anisotropic creep model for soft soils

In this paper a new anisotropic model for time-dependent behaviour of soft soils is presented. The formulation is based on a previously developed isotropic creep model, assuming rotated Modified Cam Clay ellipses as contours of volumetric creep strain rates. A rotational hardening law is adopted to account for changes in anisotropy due to viscous strains. Although this will introduce some new soil parameters, they do not need calibration as they can be expressed as functions of basic soil parameters through simple analytical expressions. To start with, the one-dimensional response of the model is discussed, making it possible to explore how the model is capable of capturing key features of viscous soft soil behaviour. Subsequently, the three-dimensional generalisation of the model is presented, followed by comparison with experimental data, showing good agreement in both triaxial undrained compression and extension. In the authors' opinion, the simple formulation of the model makes it attractive for use in engineering practice

Failure of Sterne- and Pasteur-Like Strains of Bacillus anthracis to Replicate and Survive in the Urban Bluebottle Blow Fly Calliphora vicina under Laboratory Conditions

Britta von Terzi, Peter C. B. Turnbull, Wolfgang Beyer, University of Hohenheim, Institute of Environmental and Animal Hygiene, Stuttgart, GermanySteve E. Bellan, Center for Computational Biology and Bioinformatics, University of Texas at Austin, Austin, Texas, United States of AmericaThis study aimed to elucidate the bacteriological events occurring within the gut of Calliphora vicina, selected as the European representative of blow flies held responsible for the spread of anthrax during epidemics in certain parts of the world. Green-fluorescent-protein-carrying derivatives of Bacillus anthracis were used. These lacked either one of the virulence plasmids pXO1 and pXO2 and were infected, or not infected, with a worm intestine phage (Wip4) known to influence the phenotype and survival of the pathogen. Blood meals were prepared for the flies by inoculation of sheep blood with germinated and, in case of pXO2+ strains, encapsulated cells of the four B. anthracis strains. After being fed for 4 h an initial 10 flies were externally disinfected with peracetic acid to ensure subsequent quantitation representing ingested B. anthracis only. Following neutralization, they were crushed in sterile saline. Over each of the ensuing 7 to 10 days, 10 flies were removed and processed the same way. In the absence of Wip4, strains showed steady declines to undetectable in the total B. anthracis counts, within 7–9 days. With the phage infected strains, the falls in viable counts were significantly more rapid than in their uninfected counterparts. Spores were detectable in flies for longer periods than vegetative bacteria. In line with the findings in both biting and non-biting flies of early workers our results indicate that B. anthracis does not multiply in the guts of blow flies and survival is limited to a matter of days.This work was funded by grant BE 2157/3-1 of the German Research Foundation (DFG).

Internationalism, Regionalism, and National Culture: Music Control in Bavaria, 1945–1948

For many Germans in the immediate postwar period, all that remained of their country was its art. Subjugation, destruction, the pain of unfathomable guilt: these had ripped away at the national psyche, severing nation from nationalism, person from people, the present from the past. “We are,” wrote Wolfgang Borchert in 1946, “a generation without a homecoming, because we have nothing to which we can return.” Nation: what would that word now mean? An occupied state no longer possessing statehood, a conquered people starved even of the moral strength that might come from resisting. Even if the institutions of national governance could be recreated, they could have no historical legitimacy; if Bonn were not to be Weimar, it would equally not be the kaisers’ or the Führer’s Berlin. For many, refuge from the shaming of the nation lay, as Theodor Heuss reflected, in a “decentralizing of the emotions,” in a “flight” to those fields “where the violence of the great political world shake-up is not felt so directly.” This drove literate Germans back to Goethe and music lovers to the endlessly-performed postwar symphonic cycles of Brahms and Beethoven. And yet, escaping into what Jost Hermand aptly termed “the protective wall of self-absorption” did not completely preclude connection to the national community of Germans. In fact, a powerful communion with the whole might still come through the personal enjoyment of a shared art or culture. In art might reside the essence of the national community, a stateless collectivity, without territories perhaps, but with borders and guardians nonetheless
