Positioners used in wound care are devices that elevate, transfer, place, support, or help change the position of an entire body or individual parts. They utilize air, air-permeable fabrics, fiber fill, foam, gel, or a combination of these components.
What is the definition of reverse fault? A fault along the Earth's crust is identified by the corresponding type of stress that caused its formation. In geology, a stress is defined as the amount of force exerted on a unit of surface area. Generally, shear stress forms transform faults, compressive stress creates reverse faults and tensional stress produces normal faults.
Reverse faults are dip-slip faults in which the hanging wall moves up relative to the footwall. Reverse faults are the result of compression (forces that push rocks together). The Sierra Madre fault zone of southern California is an example of reverse-fault movement. There the rocks of the San Gabriel Mountains are being pushed up and over the rocks of the San Fernando and San Gabriel valleys.
