The present invention concerns a novel, highly dispersible aluminium hydrate. The display device includes a bent portion obtained by bending an element substrate. These modules in the described embodiments include a receiving module, a determination module, a communication module, and a generation module. Also provided are neutral or cationic coordination complex dimers, so that the two palladium atoms are both bonded to one or two donor atoms from group 16, and each palladium atom is bonded to two donor atoms from group 15. Compositions and methods for eliciting an immune response to endogenous or exogenous tumor antigens. The system includes a user request interface for receiving a request from a single team member and a request manager for performing a task in response to the request and returning a result of the task to the user request interface.
