In the early 1970s, National Foam, Inc. invented alcohol-resistant AFFF technology. AR-AFFF is a synthetic foam developed for both hydrocarbon and polar-solvent materials. Polar solvents are combustible liquids that destroy conventional fire-fighting foam.
AFFF was developed in the 1960s under Project Light Water in a joint venture between 3M and the U.S. Navy. AFFF forms a film that floats out before the foam blanket, sealing the surface and smothering the fire by excluding oxygen. AFFF is widely used for ARFF firefighting at airports, often in conjunction with purple-K dry chemical.

The unit is then filled with 1.5 US gallons (5.7 L) of water and class A foam, AFFF, FFFP or commercial detergent is added to the water in a 1% ratio for class A fires and a 3%-6% ratio for class B fires. Typically, the tip of the smooth-bore application nozzle is then cut off to allow the foam to properly expand.
A History of the Modern World is a work initially published by the distinguished American historian at Princeton and Yale universities Robert Roswell Palmer in 1950. The work has since been extended by Joel Colton (from its second edition, 1956) [ 1 ] and Lloyd S. Kramer (from its ninth edition, 2001), [ 2 ] and currently counts 12 editions.
Menzies noticed that they kept encountering the year 1421 and, concluding that it must have been an extraordinary year in world history, decided to write a book about everything that happened in the world in 1421. Menzies spent years working on the book and, by the time it was finished, it was a massive volume spanning 1,500 pages.
At Swim-Two-Birds by Flann O'Brien has only one chapter: the first page is titled Chapter 1, but there are no further chapter divisions. God, A Users' Guide by Seán Moncrieff is chaptered backwards (i.e., the first chapter is chapter 20 and the last is chapter 1). The novel The Running Man by Stephen King also uses a similar chapter numbering ...
