Surgicel is a hemostatic agent (blood-clot-inducing material) made of an oxidized cellulose polymer (the unit is polyanhydroglucuronic acid), manufactured by the Ethicon subsidiary of Johnson And Johnson. It was introduced into clinical practice in 1947. It is used to control post-surgical bleeding.
Multi Stage: (More than one level of heating or cooling) Multi Stage heating means that you have two levels of heat in your home. You will perhaps have a furnace and another method of heat like a solar panel. The second level of heat is commonly referred to as an emergency heat setting.
Radiant cooling. The only negative for radiant floor heating is that itâs not so easy to use for cooling. With a conventional forced-air heating system, the same ducts that deliver hot air through ducts from the furnace can be used to introduce cool air from a central air conditioner.
