A rotatable coupling assembly for facilitating the connection and separation of a waste discharge hose between a recreational vehicle waste discharge outlet and the inlet of an external waste disposal receptacle, including a first coupling with a first fitting having a generally cylindrical main body with a flanged portion. Such commands are redirected to an IO redirection engine instead of going directly to the PC’s normal operating system where it can potentially harm files in on the hard disk. The drain of the NMOS transistor can be connected to the negative end of the fuse. The food cartridges have hinged sides which close or clamp to an opposed position for engaging and securing the food items in a food specific insert on the hinged sides sized to accommodate the food item. The format is modified periodically in accordance with the aircraft’s flight path and a decay rate of the wake turbulence. The gate stack has a first layer of high dielectric constant material, a second layer comprising a metal or metal alloy, and a third layer comprising silicon or polysilicon.
