Newer "superfine" chaff has a typical diameter of 0.7 mils (0.018 mm). The chaff is carried in tubular cartridges, which remain attached to the aircraft, each typically containing around 3 to 5 million chaff fibres. The chaff is ejected from the cartridge by a plastic piston driven by a small pyrotechnic charge. [21]
Chaff (/ tʃ æ f /; also UK: / tʃ ɑː f /) [1] is dry, scale-like plant material such as the protective seed casings of cereal grains, the scale-like parts of flowers, or finely chopped straw. Chaff cannot be digested by humans, but it may be fed to livestock , ploughed into soil, or burned.
Winnowing is a process by which chaff is separated from grain. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation. In its simplest form, it involves throwing the mixture into the air so that the wind blows away the lighter chaff, while the heavier grains fall back down for recovery.
A threshing board, also known as threshing sledge, [1] is an obsolete agricultural implement used to separate cereals from their straw; that is, to thresh. It is a thick board, made with a variety of slats, with a shape between rectangular and trapezoidal, with the frontal part somewhat narrower and curved upward (like a sled or sledge ) and ...
A Japanese winnowing basket (2007) A winnowing basket or fan is a tool for winnowing grain from chaff while removing dirt and dust too. [1] They have been used traditionally in a number of civilizations for centuries, [2] and are still in use today in some countries.
By contrast, human composting, like natural burial, is a natural process and contributes ecological value by preserving the body's nutrient material. [6] Some have argued that "natural organic reduction respects the human body and spirit, supports rather than sullies the earth, and works with nature rather than against it."
Chaff is dry inedible plant material. Chaff may also refer to: Chaff (countermeasure), a radar countermeasure for aircraft or other targets; Chaff algorithm, an algorithm for solving instances of the boolean satisfiability problem; Chaffing and winnowing, a method in cryptography to protect a message without encryption
A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).
