IPRAMA: INDUCED POLARIZATION FOR RAW MATERIALS
… properties, this thesis focuses on the Airborne Induced Polarization (AIP) method. Electromagnetic (EM) methods—both airborne (AEM) and ground-based—are known to be sensitive to induced polarization (IP) effects when surveying chargeable grounds. Although the relevance of IP phenomena in EM data …

Cross borehole induced polarization to detect subsurface NAPL at the Savannah River Site, South Carolina
Spectral induced polarization measurements were acquired in six cross-borehole panels within four boreholes at the Savannah River Site. The investigation was performed to delineate the presence of dense non-aqueous phase liquids (DNAPL) which were periodically released from the 1950's through the …

Potassium Sodium Bismuth Titanate Ceramics: Processing and Property Relationships for Higher-Temperature Electromechanical Actuation
… diffraction, dielectric measurements and field-induced polarization and strain studies. The lowest transition temperature (and subsequently the highest electromechanical activity) was obtained at the morphotropic boundary composition (x = 0.2). Higher potassium contents stabilized the …

Multiferroic Bismuth Ferrite-Lead Titanate and Iron-Gallium Crystalline Solutions: Structure-Property Investigations
… The data reveal: (i) a dramatic increase in the induced polarization; and (ii) the establishment of a remnant magnetization by a breaking of the translational invariance of a long-period cycloidal spin structure, via substituent effects. In addition, temperature dependent magnetic permeability …

Polarization of D(d,n)He³ reaction neutrons
The state of polarization of neutrons emitted at an angle of 45° (Lab) from the D(d,n)He³ reaction has been determined by observing the asymmetry in scattering from carbon. Neutrons scattered at equal angles to the right and left were detected simultaneously by two cylindrical stilbene crystals, …
