Aim: Evaluate the influence of cervical margin relocation (CMR) on stress distribution in lower first molar restored with direct nano-ceramic composite (zenit). Methods: A 3D model was modeled and used. Standardized mesio-occluso-distal (MOD) preparation consisted two models used this study mesial subgingival II. applied II using flowable or resin glass ionomer (Riva). Both were nanoceramic the...

A50-year-old man died suddenly while exercising on a treadmill at a local health club. He had no known previous cardiac history. During autopsy, a radio-opaque silicone compound was injected into the coronary arteries. The explanted heart was then imaged by electron-beam computed tomography (EBCT) using 3-mm slices. A complete 3D reconstruction was then obtained using commercially available sof...

This paper presents an investigation on the undesirable vibration of an oblique-stud stator frame in a large hydropower generator by means of experimental and finite element (FE) analysis. First, field experimental tests were performed, and the results indicate that the main vibration component comes from electromagnetic factors. Then, a 2D-magnetic and 3D-mechanical FE model was developed to i...

51 A ir-traffic controllers, military personnel, and others need displays that rapidly convey the location and other attributes of objects (such as aircraft) in 3D space. The ongoing revolution in the availability of inexpensive and fast 3D rendering technologies is allowing display designers to develop 3D prototype displays for this purpose, such as Figure 1. 1 By 3D display, we mean a display...

Soil - structure interaction behaviour of pile foundation is complex for heavier structures which suffer large lateral load due to wind, wave action etc., in addition the vertical and oblique load. The parameters involved determining capacity are its structural geometry, soil properties ground condition. different horizontal compared sloping ground; it even under loading unloading conditions. I...

the pile-raft foundation is a combination of a raft foundation with piles. pile-raft foundation has been widely designed, assuming all structure loads to be transferred to piles without considering contribution of the load taken by contact surface between raft and soil. methods of analysis currently used in practice are based upon relatively conservative assumptions of soil behavior or on the l...

PURPOSE To analyse the biomechanical characteristics of locking plates under cyclic loading compared to a nonlocking plate in a diaphyseal metacarpal fracture. METHODS Oblique diaphyseal shaft fractures in porcine metacarpal bones were created in a biomechanical fracture model. An anatomical reduction and stabilization with a nonlocking and a comparable locking plate in mono- or bicortical sc...
