Study on Charge Oscillation-Induced Low-Frequency Electric Field
Electric field induced by charge oscillation has been investigated by simulation of the electric field distribution using the finite-difference frequency-domain method. In addition, the electric field was induced by spatial oscillation of a sample to which a DC voltage was applied. The simulation and evaluation of the electric field verified that the efficiency for inducing the electric field has a proportional relationship with the amplitude displacement of a charged object, and detecting the electric field from the top to the side of the object is possible.

KERR ELECTRO-OPTIC FIELD MAPPING MEASUREMENTS IN ELECTRON BEAM IRRADIATED POLYMETHYLMETHACRYLATE
Kerr electro-optic field mapping measurements have been performed inelectron beam irradiated polymethylmethacrylate (PMMA).The accumulatedtrapped charge results in large self-electric field.The resulting numerouslight maxima and minima were recorded on photographic film and videotapeto allow accurate measurement of the time dependence of the electric fieldand space charge distribution in charging sample for various electron beamenergies,beam current and sample thickness.It was found that volumebreakdown through the electron charged region may occur spontaneouslywhen accumulated charge levels are high.
The Legacy of Art in Plastic Surgery
Summary The consistent relationship between surgery and art has been very well documented since 2000 BC. The close relationship between plastic surgery and art is historical and is still expected by the public and our patients. This article emphasizes the many links plastic surgery has with art, and presents a few practical examples of its reverberation in aesthetic and reconstructive plastic surgery procedures. Based on his surgical and actual sculpting activities in the realm of contemporary art, the author elaborates on 7 contributions art education affords the plastic surgery praxis, as an incentive and a reflection of its value to the plastic surgeon’s life.
