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.
Post and beam construction is just that: a system of horizontal beams that transfer structural loads to a system of vertical posts. More traditional post and beam construction also employs a series of diagonal braces that reinforce the beams and help to make the structure rigid. Post and beam is visually quite distinct.
