Skin has three layers:
Epidermis - The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
Dermis - The dermis, beneath the epidermis, contains tough connective tissue, hair follicles and sweat glands.
Hypodermis - The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

Skin serves several functions such as:
Regulation of body temperature.
In response to high environmental temperature or strenuous exercise, the evaporation of sweat from the skin surface helps lower an elevated body temperature to normal. In response to low environmental temperature, production of sweat is decreased, which helps conserve heat. Changes in the flow of blood to the skin also help regulate …show more content…
This usually occurs when an individual slides down the bed or chair causing abrasions or blisters.

Temperature - increased body temperature is also thought to increase the risk of pressure ulcer development.

The following study is based on 26 utilities which burn coal, have a generating capacity of at least 50 Megawatts (MW) and whose Flue Gas Desulfurization devices have been operating for at least 5 years. An analysis is made of the capital and annual costs of these systems using a comparison of four main processes: lime, limestone, dual alkali and sodium carbonate scrubbing. The functional analysis, based on operability, allows a readjustment of the annual costs and a determination of the main reasons for failure. Finally four detailed case studies are analyzed and show the evolution of cost and operability along the years.
