IEEE Transactions on Transportation Electrification
Double-sided linear motors often encounter significant detent forces. To address this issue, a double-sided asymmetric primary staggered tooth permanent magnet linear synchronous motor (DSAPST-PMLSM) is proposed to suppress detent forces.

Permanent magnet synchronous machines with fractional slot stator windings using the tooth coil technology require detailed investigations on the electromagnetic parameters due to a very low number of slots per pole and phase. Finite element analyses can provide many results but a subsequent application of the frozen permeabilities method allows for a ...

Design of Permanent Magnet Motor With Unequal Stator Tooth Width Based on Actual Winding Factor
IEEE transactions on industry applicationsThe enhancement of torque density has emerged as a significant area within the research of permanent magnet (PM) drive motors. The Unequal Tooth Width (UNET) stator configuration in certain permanent magnet brushless motors has been adopted to improve ...

In vitro evaluation of fluorescein for testing the permeability of white spots on tooth enamel.
Pediatric dentistry, 1991This investigation demonstrates the reliability of fluorescein for detecting the permeability of incipient dental caries (white spots). Artificial white spots were created on the buccal surface of 12 human bicuspids by viscous lactic acid (pH 4). Permeability of these lesions was assessed and reassessed before and after 24 and 48 hr of acid challenge ...

Tooth bleaching induces changes in the vascular permeability of rat incisor pulps.
American journal of dentistry, 2014To evaluate the inflammatory response in dental pulps of rat incisors subjected to tooth bleaching protocols with different HP concentrations and application times.42 incisors from Wistar rats were submitted to tooth bleaching using concentrations of 25% or 35% HP for treatment times of 15, 30 or 45 minutes.
