  Ultrasonic Screening - Artech Ultrasonic Systems

  5  · With Ultrasonic. With Artech ultrasonic and the contact-free, contamination-free transmission of the high-frequency vibrations, the sieve mesh remains free for a longer period of time. The reduced static friction ensures that cleaning cycles are minimized and the production process can be performed over a longer period of time.

  An Optimal Periodic Carrier Frequency PWM Scheme for Suppressing High ...

  High-frequency vibration caused by pulsewidth modulation (PWM) is a critical problem of permanent magnet synchronous motor drives for low-noise applications. Periodic carrier frequency PWM (PCFPWM) can effectively reduce high-frequency vibrations by dispersing concentrated harmonics over a wider frequency band. However, the resulting vibration …

  High-frequency plastid transformation in tobacco by …

  199321 · Abstract. We report here a 100-fold increased frequency of plastid transformation in tobacco by selection for a chimeric aadA gene encoding aminoglycoside 3"-adenylyltransferase, as compared with that obtained with mutant 16S rRNA genes. Expression of aadA confers resistance to spectinomycin and streptomycin.
