Predictive Maintenance (PdM), also known as condition-based maintenance, attempts to evaluate the condition of equipment by performing periodic or continuous (online) equipment condition monitoring.
Just below the epidermis lies the second layer, the dermis. The dermis, although it contains blood vessels, nerves, and hair follicles, is primarily made up of a protein called collagen.. This protein forms a network of fibers that provides a framework for the growth of cells and blood vessels.ust below the epidermis lies the second layer, the dermis.

Collagen Synthesis. Collagen is created by fibroblasts, which are specialized skin cells located in the dermis. Fibroblasts also produce other skin structural proteins such as elastin (a protein which gives the skin its ability to snap back) and glucosaminoglycans (GAGs).GAGs make up the ground substance that keeps the dermis hydrated.ollagen is the body's major structural protein composed of three protein chains wound together in a tight triple helix. This unique structure gives collagen a greater tensile strength than steel. Approximately 33 percent of the protein in the body is collagen.
