Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data
Archaeometry, EarlyView.Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

Archaeometry, EarlyView.Abstract Numerous isotopic studies of Scottish Mesolithic and Neolithic diets suggest a shift from marine‐based to terrestrial‐based subsistence strategies. However, bulk collagen isotope analysis may overlook low‐level marine food consumption. This study combines bulk collagen stable isotope data from four Neolithic sites (Quanterness, Rattar East ...

Boreas, EarlyView.The site of Barmaky currently marks the oldest Epigravettian occupation of north‐western Ukraine shortly after the Last Glacial Maximum (LGM), dated to around 19 cal. ka BP. Stable isotope analyses of bone collagen from six terrestrial mammals and two bird species show a comparatively highly structured palaeo‐food web.

Molar incisor hypomineralisation: current knowledge and practice
International Dental Journal, EarlyView., 2020 Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Developing Consistency in Enamel Etching by CO\u3csub\u3e2\u3c/sub\u3e Laser [PDF]
, 1994 It has been reported that CO2 laser energy can be utilized to etch enamel. However, consistency of etching has been a significant problem. This research was designed to ascertain which exposure parameters result in consistent etching of enamel.
