In at least one embodiment, a system includes an inhalation source; a plenum in fluid communication with the inhalation source; at least one challenge plethysmography mask in fluid communication with the plenum, for each challenge plethysmography mask including a mask having a cavity to receive at least a nose of a test animal, a delivery conduit in fluid communication with the plenum and the cavity of the mask, at least one exhaust conduit in fluid communication with the cavity of the mask and the plenum, and a pressure sensor attached to the mask to measure pressure within the cavity of the mask; at least one processor in electrical communication with the at least one pressure sensor, the processor configured to process an outmask put signal of the pressure sensor into respiratory data for each test animal during an exposure study; and an exhaust system in fluid communication with the plenum.

Various systems, devices, NO.sub.2 absorbents, NO.sub.2 scavengers and NO.sub.2 recuperator for generating nitric oxide are disclosed herein. According to one embodiment, an apparatus for converting nitrogen dioxide to nitric oxide can include a receptacle including an inlet, an outlet, a surface-active material coated with an aqueous solution of ascorbic acid and an absorbent wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the surface-active material and the absorbent such that nitrogen dioxide in the gas flow is converted to nitric oxide.

The present disclosure relates to a system for tracking wildlife such as game animals. The tracking system includes a drone that has a camera and a dart dispenser that dispenses a dart with a location transmitter. The drone sends images from the camera to a remote controller, where a user pilots the drone and observes animals for disease or other behaviors, and sends instructions to dispense the dart. The real-time location of the dart is then provided to a mobile application for use in tracking or hunting the animal.

A system for thermal regulation of a nebulizer is provided that is structured to deliver a chilled mist to the snout, muzzle, beak, or trunk of an animal. The system includes a container to house a nebulizer and a thermal material together and a mask to deliver the chilled mist to an animal. The thermal material acts to chill a liquid located inside the nebulizer in order to deliver a chilled mist to the animal for therapeutic purposes, such as initiating therapeutic hypothermia, or treating various respiratory illnesses such as croup, laryngobronchitis, and smoke inhalation.
