Hominin and carnivore roles during the formation of the early Middle Pleistocene site of Loreto (Venosa Basin, southern Italy)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The site of Loreto (Venosa Basin, Italy) was first discovered in 1929 and subsequently excavated during the latter half of the 20th century. The excavation revealed three archaeo‐palaeontological levels, with the lowermost level (Level A) yielding the largest number of remains.

Dolomite and Mg Calcite as Mineral Thermometers in Mortar Binders. A High Resolution Raman Spectroscopic Study

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman band characteristics of calcium carbonates from experimentally heated and recarbonated dolomite samples and of carbonate aggregates in a high‐fired gypsum mortar were correlated using high spectral and spatial resolution micro‐Raman. The band parameters of the carbonate minerals correlate to the applied burning temperature, hence allowing a ...

Improving the Raman Model for Dravite and Schorl Tourmalines by μXANES Analysis of Iron Oxidation States

open access: yesJournal of Raman Spectroscopy, EarlyView.
By integrating μRaman and μXANES techniques, one can acquire insights into the oxidation state of iron in tourmalines from the dravite–schorl series, thereby enhancing the accuracy of the Mg/(Mg + Fe2+) ratio. The observed linear correlations for P2 peak position, P1/P2 relative intensities, and WOH(3) peak position in the Raman spectrum enable the ...

Study of Garnets in Hellenistic–Roman Jewellery From the Collections of the Archaeological Museum of Thessaloniki, Greece

open access: yesJournal of Raman Spectroscopy, EarlyView.
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 ...

Treatment of Pyoderma Gangrenosum With Bimekizumab

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Pyoderma gangrenosum (PG) is an inflammatory neutrophilic dermatosis with no FDA‐approved treatments. Current therapies, including corticosteroids and immunomodulators, often show limited efficacy and nonspecific, conferring to higher risk of adverse events.

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

open access: yesLimnology and Oceanography, EarlyView.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.

Resolving the environmental factors that determine pond thermal refuge quality

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Cold thermal refuges may mitigate detrimental effects of future climate warming; yet, pond ecosystems have been largely omitted from thermal refuge research despite being globally numerous and providing critical ecosystem services. We create a formal definition for pond thermal refuge quality, then operationalize this definition by measuring ...

Pressurized plankton observatory offers a new window into deep‐sea larval behavior

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The High‐Pressure Plankton Observatory (HiPPO) is designed to quantify motions of zooplankton for behavioral study, including swimming and metabolic responses to environmental perturbations. It builds on prior chamber designs while filling gaps in capability for resolving orientation of small (< 1 mm) plankton, tracking their movements over ...
