Electrical Impedance of Isolated Amnion
Biophysical Journal, 1965 The electrical impedance of the guinea pig amniotic membrane was measured, under standardized conditions, over the frequency range of 20 to 7000 cycles/second. This impedance can be represented analytically by a simple frequency-dependent function which is precisely of the form of the Debye relaxation equation.

Discrete Geometric Homogenisation and Inverse Homogenisation of an Elliptic Operator [PDF]
, 2008 We show how to parameterise a homogenised conductivity in R² by a scalar function s(x), despite the fact that the conductivity parameter in the related up-scaled elliptic operator is typically tensor valued.

Evaluación de la composición corporal de adultos sanos por antropometría e impedancia bioeléctrica
Biomédica: revista del Instituto Nacional de Salud, 2007 Introducción. La antropometría y el análisis de la impedancia bioeléctrica o bioimpedancia son métodos de campo ampliamente utilizados en nuestro medio para la evaluación de la composición corporal; a pesar de ello, se desconoce si generan resultados ...

Three-dimensional electrical impedance tomography [PDF]
Nature, 1996 The electrical resistivity of mammalian tissues varies widely and is correlated with physiological function. Electrical impedance tomography (EIT) can be used to probe such variations in vivo, and offers a non-invasive means of imaging the internal conductivity distribution of the human body. But the computational complexity of EIT has severe practical

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
