Abstract: Described is a recombinant expression vector that enables a cell transformed to contain and express the vector to use levulinic acid as a carbon source, thereby converting levulnic acid into 2-butanne. Also described are genetically modified cells transformed to contain and express the vector and methods of using the cells to produce 2-butanone from a medium containing levulinic acid.

Abstract: A camper slide-out having pivotable chairs includes a slide-out for mounting into the side of a camper adapted so as to translate the slide-out laterally relative to the camper and above the side walls of a pickup truck when the slide-out is mounted into the camper and the camper is mounted into the bed of the pickup truck. At least one chair is pivotably mounted on in the slide-out for pivoting between a first alignment aligned fore-and-aft along the camper so that user sitting in said chair faces fore or aft, and a second alignment angularly pivoted by an angular displacement from the first alignment.
