Every late spring since 1951, the Wiener Festwochen bring performers from around the world to Vienna for an opportunity to share recent developments in performance styles and present them to a Viennese public that seems to be increasingly open to experimentation. These festival weeks solidify a specific form of Viennese self-understanding and self-representation as a culture that is rooted in performance. This essay seeks to link two recent Austrian performances—one of them was part of the Wiener Festwochen in 2016, the other was staged in downtown Linz during the past few years—to this Austrian and specifically Viennese culture of performance by reading them as contemporary articulations of a tradition of radical performance art that can be traced back to the Viennese Actionism of the sixties and later feminist articulations in the seventies and eighties. They play on the dramatic effect of these actions, specifically their joy in cruelty, chaos, and orgiastic intoxication, by staging regressions and thus making visible what has been dammed up and repressed in contemporary society.1 Just as their historical models, these two performances merge the performing and the fine arts and they highlight provocative, controversial, and, at times, violent content. But they do it in an interspecies context that adds an entire layer of complexity to the project of societal and cultural critique.

On the Performance of "Quia respexit ... omnes generationes" from J. S. Bach's Magnificat

Early 18Th Century

The modern-day custom of performing the 'omnes generationes' section from J. S. Bach's Magnificat twice as fast as the aria "Quia respexit" has its origins in Robert Franz's vocal and orchestral editions of 1864, the details of which were discussed in his Mittheilungen of 1863. Up until that time, 'omnes generationes' was inextricably connected to "Quia respexit" and formed part of the third movement of Bach's Magnificat. Moreover, when Bach revised the score in 1733, he added adagio to the beginning of "Quia respexit . . . omnes generationes," establishing the tempo for the whole movement. In this study I show that Bach's setting of this verse is in keeping with Leipzig tradition (as evidenced by the settings of Schelle, G. M. Hoffmann, Telemann, Kuhnau, and Graupner) and with early 18thcentury compositional practice; that he interpreted the verse based on Luther's 1532 exegesis on the Magnificat; that the verse must be understood theologically, as a unit; that the change in musical texture at the words 'omnes generationes' is a rhetorical device, not "dramatic effect"; and, finally, that there is no change in tempo at the words 'omnes generationes' either in Bach's setting or in any other from this period. An understanding of the early 18th-century Magnificat tradition out of which Bach's setting derives, with the knowledge of the reception of Bach's Magnificat in the mid 19th century, should help us restore Bach's tempo adagio for the movement.

AbstractIn the field of bottom-up synthetic biology, lipid membranes are the scaffold to create minimal cells and mimic reactions and processes at or across the membrane. In this context, we employ here a versatile microfluidic platform that enables precise positioning of nanoliter droplets with user-specified lipid compositions and in a defined pattern. Adjacent droplets make contact and form a droplet interface bilayer to simulate cellular membranes. Translocation of molecules across membranes are tailored by the addition of alpha-hemolysin to selected droplets. Moreover, we developed a protocol to analyze the translocation of non-fluorescent molecules between droplets with mass spectrometry. Our method is capable of automated formation of one- and two-dimensional droplet networks, which we demonstrated by connecting droplets containing different compound and enzyme solutions to perform translocation experiments and a multistep enzymatic cascade reaction across the droplet network. Our platform opens doors for creating complex artificial systems for bottom-up synthetic biology.

We note that for a wide range of porous, especially granular, ferromagnetics used as matrices of magnetic filter-separators, there is still an issue of defining their demagnetizing factor N which has a dramatic effect on the values of average magnetic permeability of these operating units of filter-separators. The work aims at filling the existent gaps in the issue, we supply N values depending on the relative size of such magnets as well as a respective generalizing phenomenological dependence which is characterized by an exponential realtion between the demagnetizing factor and relative size radical. The established relation allows obtaining real values of magnetic permeability of a short filter matrix thus providing an unbiased comparative estimate of its technological workability.
