Mizaj past, present and future
Temperament (Mizaj), as an individual factor, has great importance in traditional medicine and its use in diagnosis and treatment of diseases, as well as the individual lifestyle is very common. Since medicine moves toward Personalized Medicine, the root of individual differences will find its position in different aspects of medicine in early future. In traditional medicine, temperament is ...
متن کاملBeam-Based Calibration of the Linear Optics Model of ELSA
The Electron Stretcher Accelerator (ELSA) of Bonn University is used to provide an external electron beam of high duty factor in the energy range from 0.5–3.5 GeV for fixed target experiments. In the near future polarized electron beams will be accelerated up to the highest energies. In order to avoid depolarization of the beam by imperfection and intrinsic resonances the control of the closed ...
متن کاملTuberculosis: Past, Present and Future
Background Tuberculosis (TB) is the second-most common cause of death from infectious disease (after those due to HIV/AIDS). Roughly one-third of the world's population has been infected with M. tuberculosis, with new infections occurring in about 1% of the population each year. People with active TB can infect 10-15 other people through close contact over the course of a year. Materials and ...
متن کاملCONTROL AND DATA PROCESSING OF THE DISTRIBUTED 500 MHz NARROWBAND BEAM POSITION MONITOR SYSTEM OF ELSA
The preservation of the polarization level during acceleration of the electron beam is currently the main topic at the Electron Stretcher Accelerator (ELSA) of the University of Bonn. It can be improved by a good correction of the closed-orbit relative to the magnetic quadruple centres using the method of beam-based alignment. Beam position monitor electronics, developed in the Forschungszentru...
متن کاملCrossing Intrinsic Depolarizing Resonances in ELSA with Pulsed Betatron Tune Jump Quadrupoles
At the electron stretcher accelerator ELSA of Bonn University an external fixed target experiment using a polarized electron beam has been started. To provide a polarized beam with sufficient intensity a dedicated source for polarized electrons is used (with a GaAs-AlGaAs superlattice photocathode). To prevent depolarization during acceleration in the circular accelerators several depolarizing ...
