Neo‐Taphonomic Analysis of Prey Bone Remains Accumulated by Golden Eagle (Aquila chrysaetos): A Case of Nests in Southern France

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Growth and Variation in Fallow Deer (Dama dama L.) From Two Contrasting Habitats in Southern Britain

Acta Zoologica, EarlyView.
ABSTRACT We have compiled a unique data set on the age, sex, body weight and dimensions of over 500 European fallow deer from two contrasting areas of habitat in southern England: a high‐density managed parkland population and a lower‐density feral woodland one.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
