Plankton Size Groups. 1  Microplankton - Organisms 20-200 micrometers, e.g., phytoplankton and small zooplankton. 2  Mesoplankton - Organisms 200 micrometers to 2 centimeters, e.g., phytoplankton and zooplankton such as copepods. At this size, the plankton are visible to the naked eye.
Paraffin can also be beneficial for rehabilitation of sports injuries and other physical trauma. At the Nail Spa at FAC you can have the treatment performed as an additional service to your manicure and/or pedicure. Paraffin treatment is a form of deep heat therapy. Liquified paraffin wax is very efficient at absorbing and retaining heat. When you dip your hand or foot, for example, into the paraffin bath, heat transfers from the wax into the affected area as the wax solidifies. The heat increases circulation and relieves pain and stiffness.
Paraffin wax is an excellent electrical insulator, with a resistivity of between 10 13 and 10 17 ohm metre. This is better than nearly all other materials except some plastics (notably Teflon).It is an effective neutron moderator and was used in James Chadwick 's 1932 experiments to identify the neutron.t is distinct from kerosene, another petroleum product that is sometimes called paraffin. In chemistry, paraffin is used synonymously with alkane, indicating hydrocarbons with the general formula C n H 2n+2.
