This technology is even simpler to explain. RF is a kind of electric current that travels back and forth in different directions. It can be applied in such a way that it travels through your entire body from one side and out the other or between a 10mm gap using a small hand piece, just along the surface of your skin.
Lesson Summary. A post and lintel is an architectural system where a horizontal piece is supported by two vertical posts, or columns. This is a basic form of architecture that has been used since ancient times, but the Egyptians used it for monumental architecture, or buildings that are massive in size and scale.
This article is about the structural support. For other uses, see Post. A post is a main vertical or leaning support in a structure similar to a column or pillar but the term post generally refers to a timber but may be metal or stone. A stud in wooden or metal building construction is similar but lighter duty than a post and a strut may be similar to a stud or act as a brace. In the U.K. a strut may be very similar to a post but not carry a beam.
