Product Description
Excerpt from Nitrogen, Its Effect on Transit Temperatures and Market Quality of Western Lettuce Shipped in Piggyback Trailers The nitrogen-dispensing system in the N trailers was activated by the thermostat, except for N trailers 5, 7, and 9. The nitrogen release in these trailers was controlled by an oxygen sensor. These three N trailers also had thermostats that could shut off the supply of nitrogen if the temperature became too low. The oxygen concentration in the nmr trailers was controlled by an oxygen sensor that activated the flow Of nitrogen when the oxygen level in the trailer rose above the set point. The oxygen concentration in the N trailers was lowered initially by the same system used to refrigerate the trailer in transit. The oxygen con centration in the nmr trailers was lowered im mediately after loading by purging the trailer with nitrogen from an auxiliary supply.

#495 Earth Science in Space
Some worlds are made of sand. Some are made of water. Some are even made of salt. In science fiction and fantasy, planet can be made of whatever you want. But what does that mean for how the planets themselves work? When in doubt, throw an asteroid at it. This is a live show recorded at the 2018 Dragon Con in Atlanta Georgia. Featuring Travor Valle, Mika McKinnon, David Moscato, Scott Harris, and moderated by our own Bethany Brookshire.
