Four Types of Actuators. An actuator is a kind of motor that controls or moves mechanisms or systems. It takes hydraulic fluid, electric current or other sources of power and converts the energy to facilitate the motion.
Dercumâs disease, also known as adiposis dolorosa, is a rare disorder characterized by multiple, painful growths consisting of fatty tissue, called lipomas. They mainly occur on the trunk, the upper arms and upper legs and are found just below the skin.
Cold sores usually appear as clusters of tiny blisters on the lip. About 8 out of 10 people have the virus that causes cold sores. Most people are first infected before they are 10 years old. After this first infection, the virus remains dormant (inactive) in the nerves of the face. In some people, the virus becomes active again from time to time.
