Hybrid potential / R - matrix models for the 12 C + α system

th / 0 40 80 20 v 1 6 A ug 2 00 4 1 Hybrid potential / R - matrix models for the 12 C + α system

I present ongoing developments on hybrid models which combine the potential model, for the description of the background, with the R-matrix model, for the description of discrete states. Physical parameters of discrete states are converted into formal R-matrix parameters, taking into account the potential background. The nuclear part of this potential is constructed by a new variant of an inver...

Experimental Study on Performance of Modified Hybrid Liquid Membrane Process for Removal of Cadmium from Wastewater

Liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. In this study, a modified hybrid liquid membrane system is introduced. The setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. N-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

Evaluation of the role of system matrix in SPECT images reconstructed by OSEM technique

  Introduction: Ordered subset expectation maximization (OSEM), is an effective iterative method for SPECT image reconstruction. The aim of this study is the evaluation of the role of system matrix in OSEM image reconstruction method using four different physical beam radiation models with three detection configurations. Methods: SPECT was done with an arc of 180 deg...
