Thickness Calculation of Pigment Layers and Gold Leaves Using XRF and MA‐XRF Data

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT In this work, XRF and MA‐XRF data were used to estimate the thickness of Chromium Oxide (Cr₂O₃) pigment and gold leaf applied over Lead White (2PbCO3.Pb(OH)2). The thickness determination was based on the differential attenuation of the Pb‐Lα and Pb‐Lβ characteristic X‐rays, which allows correlating the overlying material layer with the Pb(Lα ...

Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Jasmonates enhance plants tolerance grown in Cd‐contaminated environments: A comprehensive overview

open access: yesAnnals of Applied Biology, EarlyView.
Jasmonates (JAs) enhance plant tolerance to cadmium (Cd) stress by activating antioxidant defences but may reduce Cd uptake, limiting their effectiveness for phytoremediation. This review compiles studies that evaluated the effects of JA application on plants grown in Cd‐contaminated environments. Abstract Cadmium (Cd) is a toxic heavy metal and one of

Universities and institutionalization of regional innovation policy in peripheral regions: Insights from the smart specialization in Portugal

open access: yesRegional Science Policy &Practice, EarlyView., 2023
Abstract Regional innovation policies are currently influenced by a series of territorial innovation models, with the regional innovation system (RIS) approach being one of the prominent examples. The rationale of smart specialization strategies (S3s) is deeply influenced by the RIS concept and highlights the importance of entrepreneurial discovery and

Rare but relevant: MDMA and hyponatraemia

open access: yesAddiction, EarlyView.
Abstract Conventionally used for its stimulant, empathogenic and entactogenic effects, 3,4‐methylenedioxymethamphetamine (MDMA, ecstasy) is one of the most commonly used psychoactive drugs, specifically among young adults and in nightlife and recreational party contexts.

Effects of soil physical properties on dung beetle assemblages in pasture landscapes of the Brazilian Cerrado

open access: yesAgricultural and Forest Entomology, EarlyView.
We assessed the effect of the type of soil texture (loamy sand and sandy loam) and its physical properties on dung beetle species assemblages in a pastureland region of the Brazilian Cerrado. We found a reduction in the total and paracoprid beetle abundances in loamy sand soil. Furthermore, the increase of soil compaction negatively affected the entire

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Biometric Analysis of Giant and Large Murid Remains From Matja Kuru 2, Timor‐Leste

open access: yesArchaeometry, EarlyView.
ABSTRACT Published research on Matja Kuru 2 (MK2) demonstrates its significance for understanding human lifestyle during the terminal Pleistocene and Holocene. Murids represent the most commonly identified taxa in the site, with specimens preliminarily classified as small, large and giant based on size comparisons.
