Systems for delivering a bifurcated stent to a bifurcation site include catheters andor bifurcated systems delivered therefrom. According to an example, a control circuit operates primary and backup power supplies using the higher of the primary and backup supply voltages, for switching between the power supplies. Some embodiments include receiving a first set of oil well test results from one or more measurement devices of a well test separator, storing the first set of oil well test results in a database, and annotating one or more tests of the first set oil well test results. As a result of the re-execution, an error message is displayed in the display device by the installer that failed at the installation. The analoguedigital converter chip has an adjustment device therein. The methods involve administering to a subject in need thereof a compound of Formula I or Formula II below: or a pharmaceutically acceptable salt thereof in an amount effective to treat the infection.
