Abstract: A method improving air quality and reducing healthcare-associated infections performed by a cleaning personnel includes the steps of equipping a cleaning cart with a plurality of single-use microfiber cloths and a plurality of microfiber mops, wherein the cleaning cart includes a vacuum cleaning apparatus with an extensible vacuum hose and a plurality of attachments, positioning the cleaning cart outside of an occupied patient room, vacuuming the patient room with the vacuum hose including first and second attachments, disinfecting the surfaces that a patient may contact with a first microfiber cloth soaked in a disinfectant solution, cleaning at least one bathroom fixture with a second microfiber cloth soaked in the disinfectant solution, mopping the floor area including the floor area of the patient restroom with a microfiber mop charged with a neutral cleaner, and placing the microfiber mop in a plastic bag.

Abstract: A first method is provided for in vitro selection of Lemhi and Russet Burbank potatoes for blackspot resistance using plant tissue culturing techniques. A second method is provided using at least one melanin precursor added to the tissue culturing media. The blackspot resistant potatoes produced from such methods are also provided.

Abstract: A flushing apparatus for controlling water flow in a toilet flushing system. The flushing system includes a pressure tank and differential-pressure type flush valve that opens when accumulated fluid pressure above a piston is vented to atmosphere. The apparatus includes an actuator for venting the flush valve which includes a tubular member that defines an air flow passage through the flushing apparatus. The air flow passage is selectively controlled by a blocking member which slides within and relative to the tubular actuator. The air flow passage can be used to ventilate the corresponding toilet bowl when the system is at rest.

Abstract: A toilet odor venting apparatus which fits over the top tank of a toilet in place of the usual tank cover. The apparatus draws air from the toilet bowl through the flush ring into the interior of the tank and then into the room in which the toilet is located. The apparatus includes a suction blower assembly which includes a low profile, disk-shaped impeller journalled for rotation about a vertical axis and one or more low profile electric drive motors, which are preferably DC and which operate at supersynchronous speed. The assembly further includes a special coupling for coupling rotary power from the motors to the impeller with the coupling assembly including a driven wheel journalled for rotation about a vertical axis and a drive wheel journalled for rotation about a horizontal axis. The electric motor is preferably powered by DC current from a battery.
