On Electron Paramagnetic Resonance in DPPH
... A Hall probe was used to measure the steady field B between the coils. The coils used had an adjustable spacing δ so B was measured for three values of δ. The current was kept steady at 0.5 A. The field was found to be most uniform for a coil spacing of δ = r. Hence the dependence of B on I was meas ...

A Mathematical Model to Choose Optimal Subsynchronous
... Abstract. Belt conveyors are a dominant mean of transport in modern open-pit mines in Bosnia and Herzegovina. They are usually driven by three-phase induction slip-ring motors of a nominal voltage of 6 kV and nominal power from 200 to 1000 kW. Efficiency of the transport system is the crucial parame ...
