Archaeometry, EarlyView.ABSTRACT Morphological and morphometric analysis of archaeological animal hairs offers a nondestructive method to explore past clothing. We examined hair from two 18th‐century burial areas (SP03 and SP04) in Mazamet, France. SP03 specimens exhibited a continuous medulla, a low medullary index (0.2 ± 0.03) and cuticular features suggesting goat or ...

Effects of temperature and ocean acidification on shell characteristics of Argopecten purpuratus: implications for scallop aquaculture in an upwelling-influenced area [PDF]
, 2016 Coastal upwelling regions already constitute hot spots of ocean acidification as naturally acidified waters are brought to the surface. This effect could be exacerbated by ocean acidification and warming, both caused by rising concentrations of ...

Periodontology 2000, EarlyView.Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'
