During the 14 July 2005 encounter of Cassini with Enceladus, the Cassini Plasma Spectrometer measured strong deflections in the corotating ion flow, commencing at least 27 Enceladus radii (27 × 252.1 kilometers) from Enceladus. The Cassini Radio and

The Io plasma torus apparently has a much longer lifetime than anticipated on the basis of simple theoretical stability analyses. This quandary is particularly evident at the outer edge of the torus, the plasma ramp, where the steep radial gradient i

Previous treatments of rotationally driven interchange motion assume rigid corotation and incorporate centrifugal force into an effective gravity. When the ionospheric acceleration time is short, this approximation is acceptable, but in remote region

The main source of plasma in the Jovian magnetosphere is Io and the dominant sink is outward radial transport. Conservation of angular momentum leads to a decrease in angular velocity with distance, but ionospheric coupling resists any departure from

We evaluate a number of simple, one‐point phenomenological models for the decay of energy‐containing eddies in magnetohydrodynamic (MHD) and hydrodynamic turbulence. The MHD models include effects of cross helicity and Alfvenic couplings associat

[1] At Saturn, significant plasma mass loading and radial transport occur together throughout the extended neutral torus, both producing corotation lags. We present a theory that depends upon the ratio of two classes of process: those injecting new m

The use of fabric filtration for controlling particulate emissions from power generating plants has proven effective, both technically and economically. In most installations, the collection efficiency of these systems ismuch better than is required

The tensile, or cohesive, strength of dust aggregates affects the re-entrainment of dust in electrostatic precipitators and the removal of dust cakes from fabric filters. It is also an important parameter in the rheology of fine powders. This quantit
