One of the most exciting areas in lithium ion batteries is engineering structured silicon anodes. These new materials promise to lead the next generation of batteries with significantly higher reversible charge capacity than current technologies. One drawback of these materials is that their production involves costly processing steps, limiting their application in commercial lithium ion batter...

We have measured deuteron elastic scattering cross sections at 110 MeV on C and Pb, and at 120 MeV on C and Ni, with the Texas ARM K500 cyclotron. The motivation for this experiment is that, except for some limited data above 200 MeV [1], there exists no elastic scattering data above 90 MeV. In order to calculate deuteron optical potentials in the energy range accessible by the K500 cyclotron, ...

The large angle dependence of the Hp(10) response in PADC-based personal neutron dosemeters constitutes a serious concern in operational radiation protection dosimetry. For planar dosemeters, the typical Hp(10) response falls by half or more when the incidence angle changes from 0 to 60 . To reduce this source of systematic uncertainty, configurations based on multiple detectors at different an...

We construct for the first time, the sequences of stable neutron star (NS) models capable of explaining simultaneously, the glitch healing parameters, Q, of both the pulsars, the Crab (Q ≥ 0.7) and the Vela (Q ≤ 0.2), on the basis of starquake mechanism of glitch generation. These models yield an upper bound on surface redshift of NSs, zR ≃ 0.77. If the lower limit of the observational constrai...

exposure buildup factors have been calculated by monte carlo method for point isotropic gamma ray sources, penetrating a two-layer spherical shield of water surrounded by lead, and the effect of bremsstrahlung radiation on buildup factors has, in particular, been investigated, the results of which are in good agreement with previous works. the buildup factors were then calculated for various co...

Introduction: Today, radiotherapy combined with surgery in the treatment of parotid tumors widely are used specially for high grade parotid tumors. One of concern and challenge issue of radiotherapy is that the treatment of these tumors with irregular surface due to the presence of external ear and region of different physical electron density (air cavities, dense bone, soft t...

the theoretical calculation of the energies of projectile like fragments (plfs) using the heavy-ion reactions between 76ge and 198pt are reported in this article. the incident beam energy was 635 mev. the calculated values of plfs are compared with the previous experimental results and it is shown that the theoretical calculations of plfs are consistent with the experimental values. the elastic...

A neutron source comprised of a vacuum insulated tandem accelerator and solid lithium target is in operation for development boron capture therapy other applications. The size the proton beam on surface depending current was measured using an infrared camera thermocouples inserted inside target. absence noticeable influence space charge transportation from to at distance 5 m has been establishe...

69 INTRODUCTION The success of operating a drive-thru facility depends on queues and waiting times experienced by customers. Drivethru facilities are required to provide queuing areas that can hold the expected maximum queue length. Rates of arrivals and service times affect the required queuing areas for drive-thru facilities. Gattis recommended queuing areas for drive-thru facilities located ...
