Despite the fact that different particle species can diffuse with respect to each other in neutron star (NS) cores, effect of diffusion on various phenomena associated NS oscillations is usually ignored. Here we demonstrate be extremely powerful dissipative mechanism superconducting NSs. In particular, it much more efficient than shear and bulk viscosities. This result has important implication...

Background: One of the main causes of induction of secondary cancer in radiation therapy is neutron contamination received by patients during treatment.Objective: In the present study the impact of wedge and block on neutron contamination production is investigated. The evaluations are conducted for a 15 MV Siemens Primus linear accelerator. Methods: Simulations were performed using MCNPX Monte...

The Quasi-Elastic Neutron Scattering (QENS) spectra from four cement pastes are re-analyzed by a new revised jump-diffusion and rotation-diffusion model (rJRM). From the QENS fit, it can be seen that rJRM is an improved to fit within whole detected neutron energy transfer scattering vector. By fitting, structure parameters extracted show both additives aluminum-silicate nanotubes (ASN) carboxyl...
