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.
Normal Fault. 1  In reverse faulting, the smallest (least compressive) stress is vertical. 2  The largest and intermediate stresses are horizontal. 3  The shear fracture (fault) makes an angle of less than 45 degrees with the major (most compressive) principal stress direction, in this case the horizontal.
