Germany became a modern, unified nation under the leadership of the âIron Chancellorâ Otto von Bismarck (1815-1898), who between 1862 and 1890 effectively ruled first Prussia and then all of Germany.
Laser effects on the skin. Thermal (burn) injury is the most common cause of laser induced skin damage. Thermal damage is generally associated with lasers operating at exposure times greater than 10 microseconds and in the wavelength region from the near ultraviolet to the far infrared.
The Companion therapy laser system sends photons, or packets of light energy, deep into tissue without damaging it. These photons are absorbed within the mitochondria of the cells and induce a chemical change called âphoto-bio-modulationâ. This light energy then inspires production of ATP in the cell.
