Abstract: An attachment for a tractor including a frame with a forward portion and a rear portion, the rear portion pivotally connected to the forward portion; and two or more shanks attached to the forward portion. A method of operating an attachment for a tractor including connecting an attachment to a tractor, the attachment including a frame and two or more shanks, the frame including a forward portion and a rear portion, the shanks being attached to the forward portion and pivoting the rear portion of the frame relative to the forward portion of the frame.

Abstract: A multi-lumen endotracheal tube has means for coating an inside and an outside surface of the endotracheal tube with antimicrobial and antibiofilm agents; means for releasing antimicrobial and antibiofilm agents from the endotracheal tube; means for using electrical current to enhance the efficacy of the antimicrobial and antibiofilm agents; and means for using ultrasound energy to enhance the efficacy of the antimicrobial and antibiofilm agents. In another feature of the present invention, the multi-lumen tube further has an outer lumen, and a concentric inner lumen, and the outer lumen contains the means for coating, the means for releasing, the means for using electrical current, and the means for using ultrasound energy. In another feature of the present invention, the inside and outside surfaces have a surface coating to reduce the buildup of bacteria and biofilm on the surface.
