Ceramic Raw Materials and Technological Choices in Iron Age Tyre (Lebanon): A Multiproxy, Fabric‐Based Approach

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...

Influence of carbonate apatite nanoparticles incorporated into commercial dental adhesives on immediate and long‐term microtensile bond strength

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study assessed whether integrating carbonate apatite nanoparticles with a CO3/PO4 molar ratio of 5 (CA5n) into commercial adhesives affected the immediate or the long‐term microtensile bond strength (µTBS) between composite resin and dentin.

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

open access: yesIbis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...
