Low-Energy Linear Structures in Dense Oxygen: Implications for theεPhase

non-linear study of various slit shear walls in steel structures

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

Range Distributions of Low-energy Nitrogen and Oxygen Ions in Silicon (RESEARCH NOTE)

The range distributions of low-energy nitrogen and oxygen (2-3 keV) ions is silicon are measured and compared with these available in theories. The nitrogen distribution is very close to a Gaussian distribution as predicted by theory. The oxygen profile however, indicates a surface localized peak along with a shoulder and a long tail into the sample. The surface peak is beleived to he the resul...

Structures in low-energy classical bremsstrahlung

We study classical bremsstrahlung from neutral atoms and investigate the origins of the structures in the energy dependence of the differential cross section ωdσ/dω and the asymmetry parameter a2, using soft-photon limit results in terms of elastic scattering. We show that trapping features in elastic scattering do not contribute to the structures. Rather, these structures result from the suppr...

Commissioning and early experience with a new generation low-energy linear accelerator in zahedan

Introduction: Since commissioning beam data are treated as a reference and ultimately used by treatment planning systems, it is vitally important that the collected data are of the highest quality to avoid dosimetric and patient treatment errors that may subsequently lead to a poor radiation outcome. Beam data commissioning should be performed with appropriate knowledge and pr...
