Body Iron Loss in Animals

Experimental Biology and Medicine, 1978
SummaryMeasurements have been made of the decrease in specific activity of radioiron in circulating red cells of eight animal species. From these data calculations of body iron turnover have been made and establish a general inverse relationship between body size and rate of external iron exchange.

Predicting loss in magnetic steels under arbitrary induction waveform and with minor hysteresis loops [PDF]

, 2004
We have studied ways of predicting power losses in soft magnetic laminations for generic time dependence of the periodic magnetic polarization J(t). We found that, whatever the frequency and the induction waveform, the loss behavior can be quantitatively

Identification of an iron–hepcidin complex [PDF]

, 2008
Following its identification as a liver-expressed antimicrobial peptide, the hepcidin peptide was later shown to be a key player in iron homoeostasis. It is now proposed to be the 'iron hormone' which, by interacting with the iron transporter ferroportin,

Iron deficiency anemia and iron losses after renal transplantation [PDF]

Transplant International, 2009
Iron deficiency contributes to anemia after transplantation. The magnitude of iron loss from blood loss in the peri-transplantation period has not been quantified. We prospectively estimated phlebotomy and surgical losses over the first 12-weeks following transplantation in 39 consecutive renal transplant recipients on hemodialysis (HD), peritoneal ...

Efficiency Analysis and Optimization of Two-Speed-Region Operation of Permanent Magnet Synchronous Motor Taking into Account Iron Loss Based on Linear Non-Equilibrium Thermodynamics

Machines
In this article, the linear non-equilibrium thermodynamic approach is used to mathematically describe the energy regularities of an interior permanent magnet synchronous motor (IPMSM), taking into account iron loss. The IPMSM is considered a linear power

Electromagnetic Design and Losses Analysis of a High-Speed Permanent Magnet Synchronous Motor with Toroidal Windings for Pulsed Alternator

Energies, 2018
The configuration of conventional high-speed Permanent Magnet Synchronous Motors (PMSMs) is usually long and thin, with overlong axial end winding lengths, which is not suitable for those applications that place severe restrictions on the axial length ...

Parameter Optimization for Reducing Torque Ripple and Harmonic Losses of Multi-Layered Interior Permanent-Magnet Synchronous Motors

IEEE Access, 2022
In this paper, parameter optimization of multi-layered interior permanent-magnet synchronous motors for electric vehicle propulsion is carried out to improve torque ripple and efficiency at low- and high-speed regions. First, we establish a torque ripple
