A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT The presence of microplastics (MPs) in groundwater has emerged as a significant concern due to their environmental impact and the threat they pose to vital water resources, groundwater being one of the most important freshwater sources in the world.

Double parton scattering and 3D proton structure: A Light-Front analysis

open access: yes, 2016
Double parton scattering, occurring in high energy hadron-hadron collisions, e.g. at the LHC, is usually investigated through model dependent analyses of the so called effective cross section $\sigma_{eff}$.

Near‐Synchronous Cambrian Evolution of the Transbrasiliano‐Kandi‐4°50′ Shear Zone in South America and Africa

open access: yesTerra Nova, Volume 38, Issue 2, Page 97-105, April 2026.
ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

Early Use of Lime Mortar at the Early Iron Age Piscina Torta Salt Production Site (Tiber Delta, Ostia, Italy)

open access: yesGeoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT This study presents new evidence for the early use of lime mortar during the Early Iron Age at the Piscina Torta site (Ostia, Italy), situated on the earliest Holocene beach ridges in the southern Tiber delta. The site, which was earlier described as a briquetage site, dates from between the late 8th and 6th century BCE and consists of a large

Intermediate Western Boundary Current speeds from the southeastern Brazilian margin: A 16,000‐year record from grain‐size evidence

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract This study presents a high‐resolution reconstruction of the Antarctic Intermediate Water (AAIW) transport variability on the southeastern Brazilian continental margin over the last 16,000 years BP, based on grain‐size analysis. Variations of sortable silt (SS¯$$ \overline{SS} $$) are interpreted as changes in flow speed of the Intermediate ...
