material after preparation. Crowns were ceTnented onto the teeth using zinc cement, Fuji I, Vitrerner, or C&B Metabond, The samples were thermal-cycled fer 10,OOO cycles, They were then immersed in erythrosine solution, sectioned, and observed under a microscope. Microieakage analyses were performed using a O'4 point system. The data were sLatistica!ly analyzed. There were significant differences b tween the coated specimens and the uncoated specimens using Fuji I and Vitremer. The results showed that a resin coating could decrease the amount of rnarginal leakage when applied with these two ce-

Low-temperature dopant activation technology using elevated Ge-S/D structure
Dopant activation annealing of an elevated Ge-S/D structure formed on Si was investigated for application in advanced CMOSFET fabrication. Due to the low melting point of Ge, dopant activation was observed below 600 8C. However, the low temperature annealing process resulted in high reverse-bias p–n junction leakage. A thermal process budget of 900 8C, 60 s was found to be the minimum necessary...
متن کاملA New Leakage-Resilient IBE Scheme in the Relative Leakage Model
We propose the first leakage-resilient Identity-Based Encryption (IBE) scheme with full domain hash structure. Our scheme is leakageresilient in the relative leakage model and the random oracle model under the decisional bilinear Diffie-Hellman (DBDH) assumption.
متن کاملDesigning a Full Adder Circuit Based on Quasi-Floating Gate
Since in designing the full adder circuits, full adders have been generally taken into account, so as in this paper it has been attempted to represent a full adder cell with a significant efficiency of power, speed and leakage current levels. For this objective, a comparison between five full adder circuits has been provided. Applying floating gate technology and refresh circuits in the full ad...
متن کاملCharacterization of Seepage Velocity beneath a Complex Rock Mass Dam Based on Entropy Theory
Owing to the randomness in the fracture flow system, the seepage system beneath a complex rock mass dam is inherently complex and highly uncertain, an investigation of the dam leakage by estimating the spatial distribution of the seepage field by conventional methods is quite difficult. In this paper, the entropy theory, as a relation between the definiteness and probability, is used to probabi...
متن کاملLeakage Performance of the GM + CCL Liner System for the MSW Landfill
The contaminants in the landfill leachate press pose a grave threat to environment of the soil and the groundwater beneath the landfill. Despite there being strict requirements in relevant provisions of both domestic and foreign countries for the design of the bottom liner system. Pollution of the soil and the groundwater still took place in a number of landfills because of the leakage. To inve...
