An apparatus includes a casing and a latch unit. The method comprises presenting an audio portion of the multi-modal help dialog move that explains available ways of user inquiry and presenting a corresponding graphical action performed on a user interface associated with the audio portion. A bond face of the disc is affixed to the base plate, the bond face comprising a used abrasive face that was previously used to condition polishing pads. The second substrate is electrically connected to the first substrate by the second wires. The systems and methods use a clothoid spiral as a bridging curve in the transition zones to reduce tubular stressesfailures in the design of multilateral well paths and extended reach well paths. The invention provides compositions comprising a substituted cyclodextrin, a nephrotoxic drug and a pharmaceutically acceptable carrier, where the cyclodextrin is present in an amount effective for substantially inhibiting the nephrotoxic effect of the drug.
