During the present study, a double groove texture was designed on surface of piston ring to improve sealing performance between and cylinder liner. The experimental design method used fabricate test plan according width, depth, spacing. By using thermal–structural coupling analysis method, finite element standard textured carried out simulate deformation state liner system group during working ...

A review of the literature on the use of carrier based obturation materials focusing on Thermafil and Resilon based obturator (RealSeal 1) are presented in this article. The review addressed the history, apical leakage, coronal leakage, biocompatibility, sealing ability and clinical success of Thermafil and RealSeal 1. Based on the studies gathered, this review concluded that both treatment tec...

This paper presents a new mechatronic approach of using infrared thermography combined with image processing for the quality control of a laser sealing process for food containers. The suggested approach uses an on-line infrared system to assess the heat distribution within the container seal in order to guarantee the integrity of the process. Visual image processing is then used for quality as...

As a country with high energy consumption, Chinese demand for clean has been increasing due to the gradual improvement of economy and living standards its citizens. Natural gas is one most widely used sources, vigorously promoted use alleviate environmental issues. result, China invested heavily in construction LNG receiving terminals plants coastal areas. This led rapid development industry pl...

Eighteen dogs were used to compare histopathological findings following excision of the soft palate using either a bipolar sealing device or a carbon dioxide laser. Histopathological comparisons were done at 48 and 96 hours after soft palate resection. Mean depths of tissue injury at 96 hours were 3.5 and 3.33 mm for bipolar sealing device and carbon dioxide laser, respectively. Control of hemo...
