Abstract: Methods and devices provide a secure virtual environment within a mobile device for processing documents and conducting secure activities. The methods and devices create a secure application environment in which secure data and documents may be segregated from unsecured data using document encryption, allowing the application of security policies to only the secure application environment. The creation of a secure application environment allows users to access and manipulate secure data on any mobile device, not just specifically designated secure devices, without having to secure all data on the mobile device, while providing the corporate entity with necessary document security. The methods and devices provide for securing data on a mobile device at the data level using encryption.

Abstract: A treatment system is provided for liquefied livestock waste contained in a slurry pit of a livestock confinement building or lagoon. Waste slurry is pumped through a sonication chamber where it is treated with ultrasound and energy density. The configuration of sonicator probes, the duration of treatment, and the sonication chamber design subject the animal waster therein to maximum sonic cavitation. The treatment should be such that the particle size of the waste is sufficiently reduced to suspend or dissolve the particles permanently, which greatly enhances the speed of biodegradation. Where the pits are under confinement buildings, the waste slurry may be recycled after treatment back into the slurry pit. In other cases, the waste slurry may be treated and then passed to a transient storage tank for trapping methane, and then to a lagoon, or passed directly to a lagoon.
