At the present time, ultrasonic motors have been developed for a variety of purposes such as linear motion drives and rotational drives. The elaboration of an ultrasonic motor is time-consuming, because it is developed adapting on its application. In this study, a new ultrasonic motor structure that combines a piezoelectric element and a metallic plate is elaborated. The driving principle of th...

Resorbable plate systems have been used in maxillofacial surgery to obviate the need for plate removal. However, resorbable plates and screws are very costly, and refixation with additional screws may be necessary when reduction or repositioning of the bone segment is inaccurate. Here we report the use of self-tapping metal screws for temporary fixation of a resorbable plating system in maxillo...

Introduction: Substantial disability can result from malunions of the distal radius following fracture. Restoration of accurate anatomical congruity and stable fixation is paramount to obtaining excellent clinical function of articular fractures. Internal fixation is widely accepted as the treatment of choice in achieving this goal. The dorsal radial plate (DRP) pi plate (Synthes USA) was desig...

In pelvic fracture operations, bone plate shaping is challenging and the operation time is long. To address this issue, a customized bone plate was designed and produced using selective laser melting (SLM) technology. The key steps of this study included designing the customized bone plate, metal 3D printing, vacuum heat treatment, surface post-processing, operation rehearsal, and clinical appl...

Magnesium alloy is the lightest practical metal. It has excellent specific strength and recyclability as well abundant reserves, expected to be a next-generation structural metal material following aluminum alloy. This paper investigated possibility of thin plate fabrication by applying overheating treatment melt drag method, investigating surface shape plate, grain size, size distribution, Vic...

The fluorescence spectrum of Au-clusters (8and 25-atom), which covers the spectral range 350–900 nm, is dramatically enhanced in the presence of plasmon supporting plate-well deposited nanoparticles. The wavelength-dependent metal-enhanced fluorescence (MEF spectrum) correlates well with the plasmon specific scattering spectrum, i.e. the synchronous scatter spectrum of the silver surface of pla...

A capacitor is formed when a level-sensing electrode is installed in a vessel. The metal rod of the electrode acts as one plate of the capacitor and the tank wall (or reference electrode in a non-metallic vessel) acts as the other plate. As the level of the material being measured rises, the air or gas normally surrounding the electrode is displaced by the material’s different dielectric consta...

To obtain accurate measurements for brightness temperature from the IIP radiometer, it is necessary to know the temperature of the front-end components especially low noise amplifier (LNA) and microwave terminator during measurements. For this application, all of these components will be placed on a temperature-stabilized metal plate which can be achieved by using a thermoelectric cooler (TEC)....
