Development of Compact Proton Beam Therapy System for Moving Organs

Masumi Umezawa Futaro Ebina Yusuke Fujii Koji Matsuda Kazuo Hiramoto Kikuo Umegaki, Ph.D. Hiroki Shirato, M.D., Ph.D. OVERVIEW: The use of particle beams in treating cancer, both in Japan and overseas, is growing in recognition of their ability to precisely target the dose of radiation on the cancerous tumor while minimizing the impact on surrounding organs. In particular, it is anticipated tha...

Analysis of a Beam under Moving Loads

Abstract: It is assumed that a beam made of material has a physical nonlinear behavior. This beam is analyzed under the moving concentrated and distributed continuous loads. The vibration equations of motion are derived from the Hamilton's Principle and Euler–Lagrange Equation. In this study, the amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam has b...

Alien species of parasites--some questions concerning terminology.

The article deals with some terms proposed by the proper institutions of the Council of Europe for describing the phenomenon of invasion of living organisms into new habitats. As these terms were elaborated mainly from the point of view of free leaving creatures, the goal of the authors was to discuss the possibility to adapt them for parasites species. Several propositions of resolving some di...

Dynamic Response of an Axially Moving Viscoelastic Timoshenko Beam

In this paper, the dynamic response of an axially moving viscoelastic beam with simple supports is calculated analytically based on Timoshenko theory. The beam material property is separated to shear and bulk effects. It is assumed that the beam is incompressible in bulk and viscoelastic in shear, which obeys the standard linear model with the material time derivative. The axial speed is charac...
