The specification discloses a system and related method for delaying the powering-on of a server after loss of power. The catalyst of the invention is a liquid titanium compound chelated with an imidazole ligand. The obtained attribute values are compared to a state of the computing device, user preferences, or other criteria to select at least one of the NAPs for connection with the computing device. In a second embodiment, hydraulic pump system uses a standard, readily available alternator to generate power to operate the audible alarm. Such polymers can exhibit desirable electronic properties and possess processing advantages including solution-processability andor good stability. In particular embodiments, the structure of the compounds is given by Formula I:wherein W1, W2, W3, R1, Q, X1, X2 and X3 are as described herein, to methods for the preparation and use of the compounds and to pharmaceutical compositions containing the same.
