	Palladium (EHC 226, 2002)
		Most of the palladium in the biosphere is in the form of the metal or the metal oxides, which are almost insoluble in water, are resistant to most reactions in the biosphere (e.g., abiotic degradation, ultraviolet radiation, oxidation by hydroxyl radicals) and do not volatilize into air.
		Palladium has been found in the ash of a number of plants, leading to the suggestion that palladium is more environmentally mobile and thus bioavailable to plants than is platinum.
		Palladium (as a solution of palladium(II) nitrate in the mg/litre concentration range) is frequently used as a chemical modifier to overcome interferences with the determination of various trace elements in biological materials by graphite furnace atomic absorption spectrometry (GF-AAS) (Schlemmer and Welz, 1986; Taylor et al., 1998).

	Microsoft "Palladium" Initiative Technical FAQ
		The goal with "Palladium" is to help protect software from software; that is, to provide a set of features and services that a software application can use to defend against malicious software also running on the machine (viruses running in the main operating system, keyboard sniffers, frame grabbers, etc).
		In addition, "Palladium" software can provide a mechanism to ensure that user interactions in unsafe environments (such as the Internet) can be safeguarded by software that the user trusts to protect his or her interests and wishes.
		This central principle of "Palladium," that machine owners, whether they are individual consumers or organizations, are in complete control of their machines and the programs they run, is in stark contrast with some current proposals that would mandate that all machines include monitoring systems that could arbitrarily disable content or programs.
