introduction: video-assisted clinical instruction (vacid) has been found to be a beneficial teaching tool for various fields in dentistry. the aim of this interventional study was to compare the efficacy of live conventional demonstration (cd), video teaching, and vacid (video with explanation) methods in teaching of root canal treatment to undergraduate dental students. methods and materials: ...

When performing digital music it is important to be able to acquire a comparable level of sensitivity and control to what can be achieved with acoustic instruments. By examining the links between sound and touch, new compositional and performance strategies start to emerge for performers using digital instruments. These involve technological implementations utilizing the haptic information chan...

differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...

In order to enhance the catalytic performance of SAPO-34 catalyst for the reaction of methanol to olefins (MTO), ultrasonic and microwave-assisted aging method were employed in static hydrothermal method to synthesize nano-sized SAPO-34. The effects of the application of this method on the chemical composition, morphology, surface area and total acidity of SAPO-34 were characterized by XRD, FE-...

The use of forward osmosis (FO) is of growing interest for water desalination, due to its potential energy savings. However, its industrial implementation is still limited by its actual performance limitation inwater permeation and reverse salt diffusion, due to membrane properties. Assisted forward osmosis (AFO) is a new concept, aiming at pressurising the feed solution to enhance water permea...
