A generally applicable method for the analysis of nitrates and nitrites has been used for a wide variety of samples, including human saliva, blood, drinking water, and airborne particulates. Aqueous nitrate ion is first converted to nitrobenzene by reaction with benzene (or another aromatic reactant) in the presence of a catalyst. The nitrobenzene is then(More)
Recent proposals for computer-assisted argumentation have drawn on dialectical models of argumentation. When used to assist public policy planning, such systems also raise questions of political legitimacy. Drawing on deliberative democratic theory, we elaborate normative criteria for deliberative legitimacy and illustrate their use for assessing two(More)
A highly sensitive gas chromatographic method is presented for the determination of aqueous nitrates. By suitable chemical pretreatment, this method is also applicable to the analysis of aqueous nitrites and gaseous oxides of nitrogen. The method has been applied to the analysis of drinking water, urine, and nitric acid. The technique involves the(More)
