Abstract: An expandable waterproof flood protection container. The flood protection container consists of flexible and waterproof sidewalls attached to a buoyant rim. The flood protection container is sized to accommodate boxes and consumer goods, which can be placed inside the flood protection container. If the storage area where the items in the flood protection container floods, the buoyant rim will rise with the rising water, which will draw up the waterproof sidewalls to protect the contents from the water.

Abstract: The invention relates to a method for hydrolyzing drug-glucuronic acid conjugates present in mammalian body fluids, the conjugates being derived from a narcotic analgesic, antagonist, or agonist-antagonist whose metabolism includes conjugation with glucuronic acid. The method comprises incubating the body fluid sample at from about 60.degree. to about 70.degree. C., for at least about 1 hour, with .beta.-glucuronidase derived from Patella vulgata, and substantially increases the sensitivity of chromatographic techniques for the detection of morphine and its analogues.
