Soviet Empire and Operatic Realm : Stalinist Search for the Model Soviet Opera
This paper analyzes the phenomenon of classical opera used (and abused) by the Soviet officials as an instrument to re-build imperial common consciousness on a new, Soviet ground, and, thus, create ...
Everyday Life Perspectives on Work, Home, and “the Soviet” from Estonia to Kyrgyzstan
The articles in this special section are the result of a three-year (2010–2013) teaching enhancement project “The Soviet in Everyday Life Past and Present,” funded by a Regional Seminar for Excellence in Teaching grant from the Open Society Foundation’s Higher Education Support Program. The project proposal was written by a group of social scientists from Kyrgyzstan and the United States (Laura Adams, Gulnara Aitpaeva, Serguei Oushakine, and John Schoberlein) who had been working in Soviet and post-Soviet space for decades and who were concerned about particular trends in higher education throughout the post-Soviet world.
Denitrification of PVA-immobilized denitrifying photosynthetic bacterium, Rhodobacter sphaeroides
Abstract A newly isolated denitrifying strain, Rhodobacter sphaeroides NII2 was immobilized in polyvinyl alcohol (PVA) gel, and the properties of the cells in the gel were examined. The immobilized cells had low or almost no denitrification activity, but the cells were activated by incubation in light with culture medium for denitrification containing 0.5% nitrate and no other nitrogen source. Cells grown in the dark were activated by incubation at an earlier stage and to a higher rate than the light-grown cells. The activation was markedly enhanced in the PVA gel with a low cell concentration. The immobilized cells consumed nitrate with a temporary accumulation of NO 2 and evolved nitrogen gas. The immobilized cells could use various organic compounds as electron donors for denitrification. Thus, the immobilized cells were applied to a continuous treatment of synthetic wastewater using an aparatus devised by this laboratory. The results showed an efficient removal of NO 3 -N from the test water.
