Monetary integration and purchasing power parity between Singapore and Britain during the 19th century

Asia‐Pacific Economic History Review, EarlyView.
Abstract This study examines the development of purchasing power parity between Singapore and Britain during the 19th century. Using new monthly data from 1831 to 1872, it finds that real exchange rates became more stable after the late 1850s. This convergence was supported by growing connections in international bullion markets, which reduced exchange

Chemical Stability and Bond Strength of Endodontic Sealers Exposed to Acidic, Alkaline and Protein‐Rich Environments: An In Vitro Investigation

Australian Endodontic Journal, EarlyView.
ABSTRACT The sealing performance of endodontic sealers may be influenced by environmental factors such as pH and blood‐derived proteins. This in vitro study evaluated the effects of pH variation and protein contamination on calcium ion (Ca2+) release and push‐out bond strength (BS) of a calcium silicate‐based sealer (Bio‐C Sealer) and an epoxy resin ...

Effects of Access Cavity Design on the Shaping Ability and Dentine Thickness Following Canal Preparation Using XP‐Endo Shaper or Reciproc

Australian Endodontic Journal, EarlyView.
ABSTRACT This study compared the shaping ability and remaining dentine thickness in mandibular molars prepared with traditional (TradAC) or ultraconservative (UltraAC) access cavities using Reciproc or XP‐endo Shaper instruments. Thirty‐two molars were scanned with micro‐CT before and after preparation to assess canal surface, volume, untouched walls ...
