Sobre a condenação do magnetismo animal: revisitando a história da psicologia [PDF]
O presente trabalho procura desenvolver uma reflexão crítica sobre o processo de condenação do magnetismo animal. Partindo de uma crítica às versões lineares e progressistas da história da Psicologia, nas quais o magnetismo é excluído ou pouco explorado,

O magnetismo é parte de uma interação fundamental da Natureza que, por exemplo, inclui fenómenos de atração e de repulsão entre materiais. Na realidade, o magnetismo e a eletricidade estão profundamente relacionados entre si, e as observações e estudos ao longo de anos permitiram construir a sua base teórica do eletromagnetismo, sendo disso exemplos ...

Inducing defects in the crystal lattice is a promising strategy for tuning chemical‐physical properties of nanoparticles (NPs). The introduction of lattice defects in substituted spinel ferrite NPs, performed by mild oxidation, allows to induce magnetic features that cannot be otherwise observed when the same nanomaterials are obtained by standard ...

Herein, a method for fast detection of fluctuations in structural and functional properties in metallic elements is presented. A particular application of mechanical stress in steel rail tracks is included. In this report, a method is proposed for determining the fluctuations of physical and structural properties in metallic ferromagnetic samples by ...
