Liquefaction resistance of partially saturated soils from CPTs [PDF]

open access: yes, 2019
In this paper an experimental methodology to evaluate the undrained cyclic resistance of satu-rated and partially saturated sand from cone penetration tests is presented. The proposed methodology is based on the results of (1) undrained cyclic triaxial tests carried out on fully saturated and partially saturated sand samples and (2) centrifuge cone ...

Flaring reduction solutions: How Norway, the US and Russia regulate flaring to mitigate black carbon emissions in the Arctic

open access: yesReview of European, Comparative &International Environmental Law, EarlyView.
Abstract Gas flaring is a common practice for burning excessive gas during oil and gas production. Flaring results in the release of various pollutants that contribute to climate change. In the Arctic, black carbon emissions released from flaring, in and near the region, contribute to local warming.

Permanent Revenue in an Energy‐Exporting Economy: A New Test for Fiscal Equilibrium

open access: yesReview of Development Economics, EarlyView.
ABSTRACT Fiscal disequilibrium arises when permanent expenditures (PEXP) exceed permanent revenue (PREV), a frequent risk in energy‐exporting economies reliant on volatile windfall revenues. However, existing research lacks a clear measure of these concepts and an empirical test for fiscal equilibrium.

Opportunities for the U.S. Geological Survey's National Seismic Hazard Model to Improve Seismic Risk Assessment of Critical Infrastructure

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
As fragility and risk modeling techniques and computational capabilities evolve, complemented by moving toward more routine and systematic seismic risk assessment of all buildings and critical infrastructure, the authors pose a few critical questions to investigate how the U.S. Geological Survey (USGS) National Seismic Hazard Models (NSHMs) can be used

Integrating Cooperative Dual Active Sites Onto a Plasmonic Photocatalyst for Synergistic Promotion of the Reduction and Oxidation Half‐Reactions in Ammonia Synthesis

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
An efficient N2 fixation photocatalyst, Ru‐WO3−x/CoOx, is prepared by integrating respective reduction and oxidation sites onto a plasmonic semiconductor. Owing to optimized reaction kinetics and promoted charge carrier separation by the synergistic effect between the two types of active sites, the involved reduction and oxidation half‐reactions are ...
