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.
The body louse (Pediculus humanus humanus, sometimes called Pediculus humanus corporis) is a louse that infests humans.The condition of being infested with head lice, body lice, or pubic lice is known as pediculosis. A nymph looks like an adult body louse, but is smaller. 2  Nymphs mature into adults about 9â12 days after hatching. 3  To live, it must feed on blood. 4  The adult body louse is about the size of a sesame seed (2.5â3.5 mm), has six legs, and is tan to greyish-white.
