Second-Order Pseudo-Hermitian Spin-1/2 Bosons
UniverseThe canonical quantization of a field theory for spin-1/2 massive bosons that satisfy the Klein–Gordon equation is presented. The breakdown of the usual spin–statistics connection is due to the redefinition of the dual field, rendering the theory pseudo ...

A Revised Pseudo-Second Order Kinetic Model for Adsorption, Sensitive to Changes in Sorbate and Sorbent Concentrations [PDF]
, 2020 Much contemporary research considers the development of novel sorbents for the removal of toxic contaminants. Whilst these studies often include experimental adsorption kinetics, modelling is normally limited to application of the pseudo-second order (PSO) rate equation, which provides no sensitivity towards changes in experimental conditions and thus ...

Optimization of biosorption process using cucumis melo rind for the removal of Fe, Mn and Pb ions from groundwater [PDF]
, 2002 Biosorption can be an effective technique for the treatment of metal-bearing groundwater. Several fruits and agricultural by-products demonstrated the ability to remove the heavy metals and thereby reduce the water contaminants. In the present study, the
