Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

open access: yesEnergy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

open access: yesEnergy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Energy‐Flow Regimes and Their Temporal Transitions in a PV‐Building System

open access: yesEnergy Science &Engineering, EarlyView.
Unlike production and consumption, which act as external factors, generated energy flows reflect the system's internal behavior regarding energy allocation at each time step. The combination of self‐consumption, surplus, and import of surplus energy into the power grid characterizes how electricity is routed between the building's local consumption and

The problem with abortion deserts: Reframing deserts for feminist solidarity

open access: yesFeminist Anthropology, EarlyView.
Abstract With the rise of the far right across the world, feminist scholars and activists have been drawn to the language of “abortion deserts” to describe the decimation of reproductive healthcare services. In this paper we argue that while “abortion deserts” is a rhetorically powerful category, it is too often used uncritically in ways that overlook ...

Who is a responsible woman? Understanding the scope and characteristics of responsible womanhood amongst women in Karachi

open access: yesFeminist Anthropology, EarlyView.
Abstract In this paper, we will construct and analyze intersecting definitions of womanhood among middle‐class women living in Karachi, Pakistan. Women are agents of their lives and are not passive voices. In this paper, we present narratives of women who resist “societal” narratives of womanhood to live a life of their choosing.
