Electron loss and capture processes arising in collisions of heavy low-charged ions with atoms and ions are the main charge-changing reactions in heavy-ion driven inertial fusion (HIDIF) [1]. However, at present time, virtually no experimental and theoretical data are available for removal processes involving fast heavy low-charged ions. In this work, the projectile-ionization (stripping) cross...

Excessive amounts of heavy metals adversely affect plant growth and development. Whereas some regions naturally contain high levels of heavy metals, anthropogenic release of heavy metals into the environment continuously increases soil contamination. The presence of elevated levels of heavy metal ions triggers a wide range of cellular responses including changes in gene expression and synthesis...

  In this study, relativistic Vlasov simulation of plasma for expansion of collisionless plasma for into vacuum is presented. The model is based on 1+1 dimensional phase space and electrostatic approximation. For this purpose, the electron dynamics is studied by the relativistic Vlasov equation. Regardless of the ions temperature, fluid equations are used for their dynamics. The initial electro...

Background: Removal of heavy metal ions from contaminated systems by agricultural and fruit and vegetable processing waste materials is an innovative and auspicious technology .The current study was designed for utilization of bio-adsorption white hard eggshell, as less expensive and much frequently available food waste materials, due to prospective metal bio-sorption capacity to toxic heavy me...

direct orthogonal signal correction(dosc) and savitzky-golay filters (sgf) were applied as preprocessing methods on the original and first derivative absorbance data. principle component regression (pcr), partial least squares (pls) and iterative target transformation factor analysis (ittfa), were used in spectrophotometric simultaneous determination of heavy divalent metal ions, lead, zinc,mer...
