Eddy current loss in Nd-Fe-B sintered magnets was investigated from experimental and simulated aspects. Eddy current loss was estimated from the temperature rise rate of a thermally insulated magnet when an ac field is applied to the solenoid coil. Eddy current simulation is done by the integral element method (IEM) and finite element method (FEM). Both(More)
Although free radical-mediated necrosis is implicated in many diseases such as neurodegeneration, potent anti-necrotic drugs have not yet been exploited. We found that bisindolylmaleimide I (BMI or GF 109203X), a PKC inhibitor, protected a variety of cells, including neurons, from oxidant-induced necrosis, although calphostin C, another type of PKC(More)
The injection of B16F10 melanoma cells with recombinant human tumor necrosis factor alpha (TNF-α) into the tail vein of C57BL/6 mice resulted in 2- to 25-fold more metastatic foci in the lungs than the injection of tumor cells alone. Clearly, TNF-α significantly enhanced experimental tumor metastasis. Furthermore, it enhanced the metastasis of Lewis lung(More)
The eddy current loss of a Nd-Fe-B sintered magnet is estimated from temperature rise rate of their magnets. The obtained values of the eddy current loss coincide with the simulated data of the Integral Element Method. The method of dividing magnet is found effective in the suppression of the current loss. Also, it is observed that the higher harmonic(More)
