Abstract: Composite granules that include metal-containing polymeric materials, and composite granules that include metal complex-containing polymeric materials are provided. The polymeric materials are divinylbenzene/maleic anhydride polymers, partially hydrolyzed divinylbenzene/maleic anhydride polymers, or fully hydrolyzed divinylbenzene/maleic anhydride polymers. Additionally, methods of using the composite granules that include metal-containing polymeric materials to capture volatile, basic nitrogen-containing compounds and methods of using composite granules that include zinc-containing polymeric material to detect the presence of water vapor are provided.

Abstract: Described are various embodiments of a content digitization and digitized content characterization system and method. For example, digitized content items may have content elements of interest extracted therefrom for remote characterization by a set of system users while mitigating, if not eliminating, concerns as to content privacy, confidentiality and/or security.

Abstract: Described are various embodiments of a system and method for providing enrolled users secure remote access to computer-based work originating from distinct clients. In some embodiments, the system comprises a network-accessible computing unit having a business application operating thereon and being remotely accessible by distinct network-enabled computing devices via respective secure network connection thereto. The computing unit further has one or more data storage devices operatively associated therewith or accessible thereto to maintain a user register of enrolled users and their respective work capabilities, as well as a register of computer-based tasks to be completed for the distinct clients. The system is operable select at least one of enrolled user as suitable for performing a designated task, authorize the selected user remote access to the business application to complete the designated task; and track work done by the selected user for remuneration purposes.
