Influence of undissolved gas in working liquid on dynamics of a logger hydraulic drive
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 The urgency of the discussed issue is caused by the fact that working liquids of a hydraulic drive often contain undissolved air. If the hydraulic liquid filling the device is not exposed to a vacuum, it will be a mixture of liquid and gas.

Advanced Engineering Materials, EarlyView.The dielectric elastomer‐based electropneumatic device (DE‐EPD) is a vacuum‐assisted ventricular assist device (VAD) that delivers high performance (85 mmHg, 6.8 L min−1) with low power consumption. Unlike traditional motor‐driven VADs, it is lightweight, quiet, energy‐efficient, and provides pulsatile flow. Validated in a simulated circulation system,
