The Parguera Fault System: Possible Quaternary Reactivation of Bedrock Faults in Southwest Puerto Rico

Tectonics, Volume 45, Issue 9, September 2026.
Abstract We present evidence of a previously unrecognized east‐west‐trending normal fault, named the Parguera Fault, in southwest Puerto Rico. The fault is located at the northwestern edge of seismicity from the southwest Puerto Rico seismic sequence that began in 2019, near the coastal town of La Parguera.

Pressure Drop in a Pebble Bed Reactor [PDF]

, 2010
Pressure drops over a packed bed of pebble bed reactor type are investigated. Measurement of porosity and pressure drop over the bed were carried out in a cylindrical packed bed facility. Air and water were used for working fluids.

Evaluating Forced Versus Plume‐Induced Subduction Initiation for the Talkeetna‐Bonanza Arc System: Implications for Permo‐Triassic Paleogeography of the North American Cordillera

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...

A Study on the Applicability of the Linear Superposition Principle to Overland Flow Resistance Based on HR‐PIV Technology

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Previous studies have suggested that the linear superposition principle fails for thin‐layer overland flows, yet direct experimental evidence remains scarce. This work adopts high‐resolution particle image velocimetry (HR‐PIV) to measure the 2D flow fields of grain resistance and form resistance in thin‐layer overland flows.

Ocean sediments and shifting baselines—A call to revise European habitat classifications

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Shifting baselines affect the appropriateness of existing habitat classification frameworks, potentially reducing MPA integrity and efficacy. To enable representative mapping, accurate sensitivity assessments and appropriate management of marine habitats, EUNIS classifications require more flexibility.

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, Volume 128, Issue 3, Page 480-493, September 2026.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...
