OBJECTIVE The aim of this multicenter randomized controlled clinical trial was to test posterior zirconia-ceramic fixed dental prostheses (FDPs) veneered with a computer-aided design/computer- assisted manufacture (CAD/CAM) lithium disilicate veneering ceramic (CAD-on) and manually layered zirconia veneering ceramic with respect to survival of the FDPs, and technical and biologic outcomes. ME...

abstract a great proportion of non-oil export in iran is related to tile and ceramic industry. so because of its main role in job creation, this industry is one of important industries in iran. in the recent years inefficiency in this industry caused an increase in expenses and a decrease in products quality and caused supply surplus crisis and a reduction in sales. therefore in this paper, the...

The aim of this paper is to introduce a new family low-profile resonators and filters that achieve high performance low insertion loss without the need for post-production tuning. resonator termed ceramic-element based distributed consists matrix subwavelength-length ceramic posts connected in inter-digital fashion top bottom ground planes. Such disposition elements beneficial two main reasons....

Liver diseases are life-threatening, it’s important to detect it tumor in early stages. So, for tumor detection Segmentation of the liver is a first and significant stride. Segmentation of the liver is a yet difficult undertaking in view of its intra patient variability in intensity, shape and size of the liver. The aim of this paper is to assemble a wide assortment of techniques and used CT sc...

Of the principal classes of engineering materials, ceramics are in many ways the most interesting and challenging. Many properties, or combination, of properties, not achievable with other classes of materials give ceramics enormous technical potential. The main obstacles that prevent the wider use of ceramics include insufficient reliability, reproducibility, and high cost. The physical basis ...
