Sorry, no etymologies found.
And the odor which the natural wood tree emits - why we can even replace it with a squirt or two of odorant from a plastic bottle.
Aux Sable Liquid Products said in a letter to public safety officials dated Sept. 8 and obtained by the Associated Press that the odorant is typically added at its Morris, Ill., plant.
"The lack of odorant is not itself dangerous," Aux Sable Vice President Katherine Dodds wrote in the letter.
"If odorant is absent, however, it is less likely that a propane leak will be detected."
The propane lacks proper levels of an odorant additive meant to alert consumers to propane gas leaks.
Consumers who believe they purchased the propane should contact their supplier or retailer to have their propane tested and to receive additional odorant as needed.
Urination, as we saw earlier, is the means of odorant communication most conspicuous to us.
The sniff begins with muscles in the nostrils straining to draw a current of air into them—this allows a large amount of any air-based odorant to enter the nose.
Pioneering work by Richard Axel (2004 Nobel Prize for the discovery of odorant receptors) showed that cultured mammalian cells defective in thymidine kinase could be rescued by introduction of the herpes virus thymidine kinase (tk) gene .
"This is the first time that any human odorant receptor is associated with how we experience odors," Hiroaki Matsunami of Duke University in North Carolina said in a telephone interview.
