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.

In scleroderma, the immune system is thought to stimulate cells called fibroblasts to produce too much collagen. In scleroderma, collagen forms thick connective tissue that builds up around the cells of the skin and internal organs. In milder forms, the effects of this buildup are limited to the skin and blood vessels.
