Development of the vacuum assisted closure technique. The practice of exposing a wound to sub-atmospheric pressure for an extended period to promote debridement and healing was first described by Fleischmann et al in 1993 [1], following the successful use of this technique in 15 patients with open fractures.
Physics is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity â just about anything, honestly.
Physics is the study of the basic elements of nature dealing with the key components that govern it, energy, matter and the their interaction in time and space. As such physics provides an important anchor to the to study all higher order scientific studies such us Biology and Chemistry. Without space, matter, energy and time the living organisms will not exist, and the ability to create a science that would study living things, Biology, would not exist either.
