Raman Analysis of Roman Mosaics From the Upper Guadalquivir Valley (Spain)
This work is focused on the Raman analysis of two Roman mosaics from Jaén (Spain) using portable and benchtop equipment, complemented by elemental analysis using EDXRF and petrographic analysis. The results obtained have provided a detailed characterisation of the tesserae.

The high mobility of dense pyroclastic density currents (PDCs) is commonly attributed to high gas pore pressures. However, the influence of spatial and temporal variations in pore pressure within PDCs has yet to be investigated. Theory suggests that variability in the fluidisation and aeration of a current will have a significant control on PDC flow ...

This study presents the gemological analysis of 25 garnets from Hellenistic and Roman jewellery in the Archaeological Museum of Thessaloniki using mobile Raman spectroscopy and micro‐EDXRF. The garnets are classified into three geochemical clusters, with notable differences in distribution between Thessaloniki and Pydna, suggesting distinct trading ...

This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...

Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration
This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Breeding home range selection of Eastern Population sandhill cranes across the boreal forest
We evaluated breeding home range habitat selection of sandhill cranes (Antigone canadensis) in the boreal forest of eastern Canada. Overall, we found that sandhill cranes selected breeding home ranges with greater proportions of wetlands, cropland, and recently disturbed forest.
