Influence of Drying Protocol on the Setting and Crystalline Phase Formation of Calcium Silicate‐Based Sealers

Australian Endodontic Journal, EarlyView.
ABSTRACT The objective of this study was to assess the hydration, crystalline structure, and setting of bioceramic ready‐to‐use and powder/liquid sealers in dry and wet root canal dentine. Thirty‐two single‐rooted human teeth were embedded in acrylic resin and sectioned into 2‐mm segments.

Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

Archaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Wet Season Carbon (δ13C) and Nitrogen (δ15N) Composition of Modern Plants as Isotopic Framework for Agropastoral and Palaeoecological Studies in Northern Greece

Archaeometry, EarlyView.
ABSTRACT Mediterranean wetlands are one of Europe's most vital and endangered biodiversity hotspots. This study determined the carbon (δ13C) and nitrogen (δ15N) isotope values of modern plants to construct an isotopic framework by which to contextualize agropastoral management in and around past wetland ecosystems.

Assessing Mobility Among Inferred Elites Interred in Crypts 1–3 on Kom H at Tungul (Old Dongola), Sudan

Archaeometry, EarlyView.
ABSTRACT As the capital of Makuria, Tungul was a major sociopolitical center within medieval Nubia, being the seat of a bishopric and a monastic community. During the excavation of the Kom H monastery, three burial crypts (Crypts 1–3) were uncovered.
