Particle‐Scale Mechanics of a Regolith‐Type Soil

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The existing studies have reported that the surface of Mars shows the presence of materials having igneous origin, including basalt and regolith‐type coarse soils. These findings are affected by significant uncertainties and, therefore, the selection of simulants for various exploration applications, including surface mobility of rovers ...

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Do large earthquakes start with a precursory phase of slow slip?

Seismica
In a recent publication, we showed that a stack of all GPS time series recorded before Magnitude ≥ 7.0 earthquakes suggests that large earthquakes start with a precursory phase of accelerating slow slip (Bletery and Nocquet, 2023).

Hydro‐Mechanical Modelling of Gas Migration in Bentonite: Formulation and Laboratory‐Scale Validation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...

Crisis Preparation, Capacity Building, and Community Resilience: Lessons From Maui

Nonprofit Management and Leadership, EarlyView.
ABSTRACT The 2023 Maui wildfires provide a unique context to explore the impact of nonprofit crisis networks taking a proactive role in community crisis response, leveraging resources, expertise, and networks. The Hawaiʻi Community Foundation (HCF) has been a key player in Maui's local response, providing critical support, mobilizing volunteers, and ...

Fundraising as Contracting: Why Nonprofits Accept In‐Kind Donations

Nonprofit Management and Leadership, EarlyView.
ABSTRACT In‐kind (nonmonetary) donations are a popular form of philanthropy that have received much less scholarly attention than monetary gifts. This study documents the prevalence of types of in‐kind giving and associated organizational practices, then explores links between the perceptions of nonprofit managers, organizational practices, and ...
