Abstract: A new and distinct variety of garlic plant, Allium sativum L., named ‘NEVADA 19’, particularly characterized by suitability for growing under climatic conditions such as prevailing in Nevada and California, regular bulb structure, good storage quality, white cover scale color, good clove peeling ability; and mid-season bulb harvest time.

Abstract: An air treatment unit may include an air inlet to receive a flow of input air for treatment and a reaction reservoir configured to hold an aqueous air treatment solution. The air treatment unit may also include an air dispersing element flow connected with the air inlet, wherein the air dispersing element is configured to convert at least a portion of the flow of input air into a plurality of microbubbles for introduction into the aqueous air treatment solution, such that an amount of one or more target gas species contained within the plurality of microbubbles is reduced through reaction with the aqueous air treatment solution. The unit may include an air outlet configured to output treated air from the reaction reservoir.
