Measurements of the attenuation of sound in water containing air bubbles were undertaken in order to confirm some aspects of a theory due to L. L. Foldy. Bubbles were produced by forcing compressed air through the cloth covering of several trays lying on the bottom of the Black Moshannon Lake. The distribution in size of the bubbles and the number of bubbles per unit volume were determined by photographing the bubbles and by collecting the volume of air which rose over a given area in a given time, the terminal velocity of rise being a known function of bubble diameter. The attenuation of sound was found to be very large at frequencies for which resonant bubbles were present, and much smaller at other frequencies, indicating that resonance absorption was the principal phenomenon observed. For the particular bubble distribution investigated, which contained 0.045 percent air by volume, the attenuation was found to be in satisfactory agreement with the theory and a maximum attenuation of approximately 20 db...

In this article we discuss the Dutch literary magazine Das Magazin (2011-present) in the light of three hypotheses about the functioning of literary magazines as communities in present-day culture: the makers refuse to be part of the linear narrative of conventional modern literary history by not positioning themselves against their predecessors’ poetics or literary practice; the authorship that is practiced and represented in the community is a symptom of the current emancipation of the heteronomous writer, and: within the community there is no disdain for the fan culture of readers without self-evident knowledge of the conventions of the autonomous literary field.
