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.
Faults of different types are charcteristic of the stress field in which they formed. Faults are nothing more than failure of the crust in shear. The crust is generally in a triaxial state of stress with three principal stress directions, one vertical and two horizontal (like a set of cartesian axes). 1  In normal faulting, the largest (most compressive) stress is vertical.
