The losses of iron in whole body cell-free sweat were determined in eleven healthy men. A new experimental design was used with a very careful cleaning procedure of the skin and repeated consecutive sampling periods of sweat in a sauna. The purpose was to achieve a steady state of sweat iron losses with minimal influence from iron originating from ...

Analysis of iron losses in induction motor with an improved iron-loss model
2014 IEEE Conference and Expo Transportation Electrification Asia-Pacific (ITEC Asia-Pacific), 2014In order to study iron loss distribution characteristics in stator and motor of induction motor, an improved iron-loss model with higher accuracy is proposed based on time-stepping finite elements. In Section Two,various iron loss formulaes are compared. followed by an miproved iron-loss model.

IEEE Transactions on Magnetics, 1974
Measurements of total power loss and domain-wall spacing have been made on individual grains in polycrystalline specimens of commercial grain-oriented 3% silicon-iron material. The loss-per-cycle against frequency characteristic of a grain is found to consist of discrete linear portions, which correspond to different domain-wall spacings. These changes

Variation in the form of iron in beef and lamb meat and losses of iron during cooking and storage [PDF]
International Journal of Food Science and Technology, 2003 Iron levels were lower in semitendinosus muscle of beef and lamb than in longissimus or triceps brachii muscles, and were lower for muscles of male than female lambs, but were similar for muscles from bulls, heifers and mature cows.

Prediction of iron losses of wound core distribution transformers based on artificial neural networks [PDF]
Neurocomputing, 1998 This paper presents an artificial neural network (ANN) approach to predicting and classifying distribution transformer specific iron losses, i.e., losses per weight unit.

Iron loss in machines with powdered iron stators
IEEE International Electric Machines and Drives Conference. IEMDC'99. Proceedings (Cat. No.99EX272), 2003This paper describes iron loss measurements in a permanent magnet servomotor, which has a stator constructed with soft magnetic composites (SMCs). It is shown that whilst the SMC has significantly greater iron loss density than silicon iron steel, it has many other advantages. The SMC machine is shown to outperform its conventional laminated equivalent.

Armature Iron Losses in Series Motors
Transactions of the American Institute of Electrical Engineers, 1949IN AN A-C series motor, the flux pulsation in the field is predominantly at line frequency. The field iron loss can be computed easily and represented by a loss component in the magnetizing current. However, due to the rotation of the armature, the gap flux is rotating relative to the armature, as well as pulsating.

Annual Iron Loss Associated with Hemodialysis
American Journal of Nephrology, 2016<b><i>Background:</i></b> In order to keep up the optimal iron status in chronic hemodialysis patients, it is important to know how much iron is lost due to hemodialysis. Residual blood associated with the hemodialysis procedure together with blood sampling inevitably causes the loss of iron in chronic hemodialysis patients ...

The determination of menstrual iron loss
Biochemical Medicine, 1970Abstract A procedure involving dry ashing and spectrophotometry with thioglycollic acid is described for the determination of iron loss during menstruation. In its development the nonvolatility of iron was checked and wet-oxidation and dry-ashing methods of destroying organic matter compared with special reference to citrated whole blood.
