Abstract: A saliva-based testing method that bypasses the need for RNA isolation/purification is described herein. In experiments with inactivated SARS-CoV-2 virus spiked into saliva, this method has a limit of detection of 500-1000 viral particles per mL, rivalling the standard NP swab method. Initial studies showed excellent performance with 100 clinical samples. This saliva-based process is operationally simple, utilizes readily available materials, and can be easily implemented by existing testing sites thus allowing for high-throughput, rapid, and repeat testing of large populations.

Abstract: A platform dolly system that has first and second dolly devices. Each of the dolly devices has a power unit, a frame, a suspension and a wheel rotatably secured to an axle. A control unit remote to the first and second dolly devices is presented that is in over the air electronic communication with the power unit of each of the first and second dolly devices in order to either simultaneously or independently control the first and second dolly devices depending upon the mode of the control unit.

Abstract: A remote controlled load transport system that has a frame with a retractable gate assembly that is able to retract in order to accommodate a load. A control system is provided having a drive that operates and rotates and steers a wheel. The control system and the gate are remotely controlled by an electronic controller that is in electronic communication with the control system to remotely operate the transport system, open the gate, lift a load and haul the load to a desired location.

Abstract: A refiner disc and segment for a rotary disc fiber refiner which has a plurality of radial fields each having an angular extent no greater than 30° and preferably no greater than 22° for reducing the amplitude and duration of load swings that take place during pumping and holdback cycles. Each field has a refining zone with a refiner groove and a refiner bar and a second zone disposed radially outwardly of the refining zone that changes the direction of flow of stock to reduce stock flow momentum and magnitude of the load swings. Each field can have a third zone radially outward of the second zone that further changes the direction of flow of stock and an infeed zone radially inwardly of the refining zone. If desired, a zone that includes a breaker bar can be disposed radially inwardly of the infeed zone. Where the disc is segmented, the segment has at least three fields.
