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 ...

Semidiaphanam Tremuli Narcissuli Ideam Lacteam: Ehrenfried Walther von Tschirnhaus (1651–1708) and His Determined Search for the Porcelain Principle

Archaeometry, EarlyView.
ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...

‘Quanto Vale a Sua Vida?’: Individuals' Resistance Under Corporate Repression

Bulletin of Latin American Research, EarlyView.
In Minas Gerais, Brazil, activists challenging Vale's extractive activities are often portrayed as obstacles to economic progress, while their resistance is criminalised. Paradoxically, as corporate repression intensifies, individual forms of dissent persist and evolve.

De Geer moraine internal architecture based on sedimentological and geophysical investigations and implications for ice‐marginal reconstructions

Boreas, EarlyView.
De Geer moraines may act as valuable ice‐marginal indicators; however, to date, their variable mode of formation has presented challenges for this utility. Here, we present sedimentological and ground penetrating radar data of DGMs located in southwest Finland.
