MAGNETIC RESONANCE (MR) IMAGING is contraindicated in patients with certain ferromagnetic implants, devices, and materials, primarily because of the hazards associated with movement or dislodgment (1). This is particularly true for metallic implants located in sensitive areas of the body, such as in

Abstract
For proper applications of the Stoner condition, we describe the assumptions in its underlying theory and their implications that need to be considered in practice. The nature of Stoner exchange parameters is examined based on spin‐polarization perturbational orbital theory and a connection has been made in understanding the parameters with both local spin density and Hartree‐Fock approximations via a self‐interaction‐corrected local spin density (SIC‐LSD) exchange‐correlation functional. © 2008 Wiley Periodicals, Inc.

Reductive conditions in soils can lead to the dissolution of iron and manganese oxyhydroxides, releasing heavy metal pollutants (e.g., Pb and Cd) bound to them. The present study used hydroxylamine as a reducing agent. Laboratory batch experiments were conducted, varying pH and hydroxylamine concent
