A variation of the sliding mode where a single layer of dielectric material slides over and back on two laterally separated tribo-layers is known as the ‘free-standing mode’ - see Fig. 3b. 2.2 Piezoelectric and triboelectric materials Materials that can generate electric charge under external ...
Echinoderm Responses to Variation in Salinity 1.1 Echinoderm distribution and diversity In her classic treatise, The Invertebrates, Hyman (1955) described the phylum Echinodermata as “exclusively marine [and] among the most common and widely spread of marine animals. They occur in all seas and at...

Advances in microvascular surgery has allowed increased use of free flaps as part of surgical reconstruction. This case report illustrates a rare anatomical variation of the radial forearm free flap pedicle which has been reported four times in the literature, and how we adapted our surgical ...
Process to regulate the operating speed of a knitting machine rotary actuator by variation of direct current voltage linked to angular encoderAn automated knitting machine has an electric motor shaft (1) whose speed is regulated by changing the actuator (2) voltage. The piezo-ceramic actuators are...
