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 ...

Intelligent Continuum Micromachines in Complex Confined Spaces
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

The Political Ecology of the ‘New’ Feminism in Late‐1990s Britain
ABSTRACT The 1990s were a vexed time for feminists in Britain. Cultural commentators declared that feminism's key battles had been won, and that given women's ascendency across various political and cultural barometers of success, the country was entering a newly ‘postfeminist’ era.

Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI
Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.

On Sucker Rod Pump Systems with Data Analysis
A sucker rod pump is an artificial lift system widely used in oil wells to extract crude oil from deep underground. Due to the clearance between the barrel and the pump plunger, a phenomenon termed slippage occurs in which the annulus column of oil ...
