This review paper is about development and evolution of nanocomposites to smart materials. With the idea formulating dental materials with long lasting maintenance functionality, it important incorporate certain features such as polymer nanofibers, natural fibers, clay, nanoclays, metal oxides, carbon nano fillers, metallic particles sulphides different ions. Therefore, helps deal both external...

objective(s):   the production of nano-hydroxyapatite by two encapsulated bacterial strains was the goal of current research.  materials and methods:   serratia marcscens atcc 14756 and pseudomonas aeruginosa ptcc 1570 were used by two methods including encapsulated form in 2% (w/v) alginate sodium powder and inoculated form (10%) in nutrient broth medium containing alginate sodium blank beads....

The effect of reducing the thinning rate when flow forming AZ31B magnesium alloy barrels on microstructure, crystal orientation, micro-, nano- and macro-mechanical properties was investigated. results demonstrate that undergoes different degrees plastic deformation after forming, grain size dislocation density inside change greatly, evolution pattern organization has a significant mechanical ma...

This review aims to provide a comprehensive overview of nano- and microscopic materials that can thermal radiation insulation without reducing visible light transmittance, thereby heat loss conserving energy in greenhouses. We also reviewed the radial properties greenhouse covering materials. Fillers, colorants, reinforcers, additives, as well glass, plastic film, sheet materials, were discusse...

background: many attempts have been performed and continued for improvement of dental amalgam properties during last decades. the aim of present research was fabrication and characterization of amalgam/titania nano composite and evaluation of its corrosion behavior. materials and methods: in this experimental research, nano particles of titania were added to initial amalgam alloy powder and the...

We examined whether fillers (filled pauses) in a Japanese lecture appeared more frequently after discourse segment boundaries (DSB) than after other sentence boundaries. Contrary to our hypothesis that fillers occur more often after DSB than after other sentence boundaries, the frequency of fillers in the first phrase after DSB did not differ statistically from that after other sentence boundar...

This paper proposes a novel method to construct a spoken language model including fillers from a corpus including no fillers using a filler prediction model. It consists of two submodels: a filler insertion model which predicts places where fillers should be inserted, and a filler selection model which predicts appropriate fillers for given places. It converts a corpus that covers domain-releva...
