It has been known for decades that a ferromagnetic sample can depolarize transmitted neutron beam. This effect was used and developed into the neutron-depolarization technique to investigate magnetic structure of materials. Since polarization evolves continuously as neutrons move through sample, initial spin states on scattering will be different at depths within sample. leads contamination mea...

One of the most informative methods for studying dielectric materials is analysis their polarization and depolarization processes. The suitable representation diagram in complex plane (Argand diagram). Often, represented as a collection intersecting parts circles, at least preprocessing. paper proposes means modeling by set circles.

Onset of QRS was compared between simultaneously recorded conventional ECG leads in 84 subjects with clinically normal hearts from a defined population sample. Mean onset of QRS was 6.4 msec earlier in lead V1 and 7.4 msec earlier in V2 than in lead II. These differences were statistically significant. The measuring system was adapted from drafting techniques and took into account variations in...
