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, a protein, supports and your body's tissues and, literally, keeps your body from falling apart. Collagen is the primary component of the body's connective tissue. About 80% of the dermis -- the part of your skin that's under the epidermis (outer layer) -- is collagen.Collagen gives your skin strength.ollagen and elastin are fibers that make up the supporting structure of the skin. Collagen gives skin its firmness while elastin keeps skin tight. Both of these fibers are plentiful in young skin and start to break down with natural aging and as a result of sun exposure.
