Exsanguination incapacitate swine, poultry and domestic sheep, whereas a chemical is used for injured livestock. Continued pumping operation of the heart during exsanguination increases the rate of depletion, and thus hastens death, by raising the fluid pressure of the blood. Because the heart operates like a positive displacement pump, reduction of blood volume will not affect efficiency of cardiac output—deprivation of blood to the heart does gradually result in diminished function, but concurrently with similar death of other parts in the body. Quickly after the animal is incapacitated it is hung upside down by its hind limbs and an extremely sharp
Wubi method feature is the use of the 'z' key as a wildcard. The Wubi method was actually designed with this feature in mind; this is why no components are assigned to the z key. Basically, one can type a z when unsure what the component should be, and the input method will help complete it. If one knew, for example, that the character ought to start with "kt", but was unsure what the next component should be, typing "ktz" would produce a list of all characters starting with "kt". In practice though, many input method engines use a tabular lookup method
