Journal of the Royal Anthropological Institute, EarlyView.Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

, 2012 International audienceWhen a transparency printed with a first halftone color is deposited on top of a paper printed with a second halftone color, we obtain a third color that we are able to predict in both reflectance and transmittance modes, thanks to ...

Contact Dermatitis, EarlyView.Disposable glove reuse reduced chemical protection during repeated hair‐dye exposure. Under ASTM F739 testing, natural‐rubber‐latex deteriorated rapidly after one reuse, whereas neoprene performed better initially but also declined over repeated cycles. Wash type had no significant effect. These findings support single‐use only and discourage the reuse

Chromium and Cobalt in Used Leather Items: A Danish Market Survey
Contact Dermatitis, EarlyView.Used leather items from the Danish second‐hand market frequently release chromium(VI) and, in some cases, cobalt. Some items exceed current EU limits, highlighting a persistent but underrecognised source of exposure in the circular economy that may contribute to ongoing contact allergy despite existing regulations.

The plasticisation model of dye diffusion: Part 8
Coloration Technology, EarlyView.Abstract Re‐evaluation using the Williams–Landel–Ferry equation, of exhaustion/rate of dyeing/fixation data previously reported for and acid dye, natural dye and two reactive dyes on three different types of silk substrate revealed that thermally activated dye diffusivity is governed by the thermally regulated structural relaxation times of the ...

Hot-pressed silicon nitride with various lanthanide oxides as sintering additives [PDF]
The effects of addition of various lanthanide oxides and their mixture with Y2O3 on the sintering of Si3N4 were investigated. The addition of simple and mixed lanthanide oxides promoted the densification of Si3N4 in hot-pressing at 1800 C under 300-400kg/
