Burkhard Dick
Burkhard Dick (born 1963 in Brake, Lower Saxony) is a German ophthalmologist who has specialized in refractive and cataract surgery. With his many contributions to the scientific literature on this topic, he is considered one of the pioneers of employing the femtosecond laser in cataract surgery. In the "Power List 2018" ranking of the world's most influential ophthalmologists by the publication The Ophthalmologist, Burkhard Dick was listed among the Top 20. Biography Dick attended high school in his hometown of Brake and graduated in 1983. After studying medicine at University of Giessen, he began his specialization as an eye surgeon. As a board certified ophthalmologist, Dick in 1996 joined the eye hospital of the University of Mainz where he became a full professor in 2003. In 2006, Dick was appointed chair of the department of ophthalmology at the University of Bochum and director of the University Eye Clinic. He turned the clinic into one of the surgical centers with the hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brake
A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. Background Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use. Other methods convert kinetic energy into potential energy in such stored forms as pressurized air or pressurized oil. Eddy current brakes use magnetic fields to convert kinetic energy into electric current in the brake disc, fin, or rail, which is converted into heat. Still other braking methods even transform kinetic energy into different forms, for example by transferring the energy to a rotating flywheel. Brakes are generally ...
