Carbon dioxide (CO 2) is usually pumped as a liquid, usually below 5Â°C (41Â°F) and a pressure of about 50 bar. The solvent is pumped as a liquid as it is then almost incompressible; if it was pumped as a supercritical fluid, much of the pump stroke would be used up in compressing the fluid, rather than pumping it.
Lice can live up to a month and can lay up to 10 eggs a day. An egg takes 7-10 days to hatch. A nymph is a baby louse. A nymph takes 7-10 days to mature into an adult louse. Only adults can lay eggs. The dark brown eggs are the newly laid eggs.
Pubic lice (Sing: pubic louse), also known as crab louse, crabs, or Fullers; Latin name Pthirus pubis are tiny parasitic blood-sucking wingless insects that infest the human genitals, causing itching and red spots. The only other animal known to be affected by this insect is the gorilla.
