I've only read the extract which imo isn't abstract
Can you link me to the extract please?
There is a link above.
OK my memory wasn't perfect OK "Brand new carpet squares 20 cm 20 cm were purchased and used as the
medium for the odor transport.
Before the initiation of this investigation, the
carpet squares were stored in airtight containers outside the boundaries of the
Institute of Legal Medicine.The two bodies were placed in a supine position on top of a new and clean
table and a separate table was used for each individual. A cotton blanket was
wrapped around each body to preclude the direct contamination of the carpet
squares with the bodies while at the same time simulating a thin layer of
clothing covering each individual."
So at some stage they are taken out of the airtight containers but a cotton blanket is the separation between the cadaver and the carpet square.
"Abstract" is the right word to use for an enticement to purchase the main article.
