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.

Tendons and ligaments also contain proteoglycans, elastin, and fibroblast cells. The collagen, elastin, and proteoglycans form the extracellular matrix. The fibroblast cells are embedded in the matrix and in fact synthesize and secrete the matrix collagen, elastin, and proteoglycans.
