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 ...

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 ...

Magnetic Field Characteristics and Stator Core Losses of High-Speed Permanent Magnet Synchronous Motors

Energies, 2020
This study focuses on the core losses in the stator region of high-speed permanent magnet synchronous motors, magnetic field characteristics in the load region, and variations in iron losses caused by changes in these areas.

Sub-assembly experiments to determine PWM supply-induced losses in electric machines

The Journal of Engineering, 2019
This paper presents a low-cost approach to experimentally characterise the effect of the inverter supply on the losses in an electrical machine. The set-up comprises of representative subassemblies of the stator and winding, referred to as ‘motorettes ...

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.

The Dermal Loss of Iron.

Experimental Biology and Medicine, 1950
Summary“Cell poor” and “cell rich” sweat samples from 25 normal subjects have been analyzed (total of 118 determinations). The iron content of “cell poor” sweat was negligible. On the other hand “cell rich” sweat contained a high concentration of iron.

Iron Loss Prediction Using Modified IEM-Formula during the Field Weakening for Permanent Magnet Synchronous Machines

Machines, 2017
During field weakening operation time (FWOT), the total iron loss rises and affects the accuracy of loss prediction and efficiency, especially if a large range of FWOT exists due to a large voltage drop that was rooted from the resistance of the used ...

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
