The invention provides a new hybrid 4-in-1 power controller chip for a PC mainboard which integrates a synchronous buck switching regulator to supply the CPU core voltage, a standard buck switching regulator for IO circuits, a linear controller for the GTL bus, and a linear regulator with built-in pass transistor for a clock generator. The complexes are useful as peroxynitrite decomposition catalysts. A request for an execution of a snap shot output to components, such as the application, a device driver and the like, is outputted to the manager. In the illustrative embodiment, the switching mechanism includes a set of switches for selectively connecting each of the capacitive elements to the capacitive load and a switch control mechanism for selectively activating the switches. Such improvements result from the presence in the medium of an effective microbial inhibiting amount of active bromine in the medium, which amount results from the addition to water before it enters the tank or while it is in the tank, or both, of at least one of the above 1,3-dibromo-5,5-dialkylhydantoins, andor a solution thereof. The present invention also provides a method for making such an article, and a method and a system for holographically recording a spatial light distribution to such an article.
