STATEMENT OF PROBLEM Streptococcus mutans can adhere at restored tooth margins to cause recurrent caries. Limited information about surface quality and bacterial adherence is available for lithium disilicate ceramic materials. PURPOSE The purpose of this in vitro study was to investigate how bacterial adherence is influenced by commercially available preparations of lithium disilicate ceramic...

Recently, in the Southern necropolis of Apulum, an inkwell with lead-glaze was discovered, which had been deposited as funerary inventory a cremation tomb. Only one other ceramic from pottery centre Micăsasa known Dacia. The shape piece is unique and represents transposition metal-made inkwells. Various technological aspects suggest local production area ancient cities where two workshops glaze...

The electrical performance of transmission line insulators will decrease dramatically under ice-covered conditions, and ice flashover may occur operating voltage. There is no direct effective monitoring method for cover on lines. In this paper, the interface quasi-distributed fibre Bragg grating (FBG) used to study positioning detection glaze icing loads composite insulators, a mechanical lever...

The Linfen kiln complex, one of the most representative Shanxi kilns, is famous for its oil spotted glazed ware production. In this work, micro-Raman spectroscopy was applied to analyze nature rusty spot pattern a bowl fragment from kilns. Crystals polygonal shape found in spots at glaze surface and around bubbles cross-section were identified as hematite. Their distribution suggests that nucle...
