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.
Scalars and Vectors. Physics is a mathematical science. The underlying concepts and principles have a mathematical basis. Throughout the course of our study of physics, we will encounter a variety of concepts that have a mathematical basis associated with them.calars and Vectors. Physics is a mathematical science.
