Abstract: A method for characterizing oxidative stress. The method includes dosing a ratio of HNE-to-DHN-protein in blood; comparing the ratio of HNE-to-DHN-protein in blood to a predetermined interval of ratio values associated with a predetermined level of oxidative stress; and classifying the oxidative stress as having reached the predetermined level if the ratio of HNE-to-DHN-protein in blood is within the predetermined interval of ratio values.

Abstract: The present invention provides a system for the identification of the phase of conductors in electrical circuits, at junctions location, regardless if the connectors are connected to ground. The system comprises two independent generators connectable to the phase conductors by electromagnetic coupling, and at any available location along these conductors, and generating different audio signals. An appropriate receiver is provided and connected to the phase conductors, at selected locations for the identification of the different audio signals. The present invention also provides a method for the identification of the phase of conductors in an electrical circuit, even when the conductors are connected to ground above the selected location for effecting the identification. The method consists in connecting, by electromagnetic coupling, two independent generators generating different audio signals, in pre-identified phase conductors.
