“Swallowed by a Black Hole”: The Neglected Impact of Endometriosis in the Workplace
ABSTRACT This study examines how endometriosis, as a chronic and cyclical condition, is experienced and managed in contemporary workplaces, and what this reveals about the limits of existing human resource management (HRM) frameworks. Drawing on Feminist Disability Theory (FDT), we conceptualise endometriosis as a form of structurally produced ...

A dual-motor drive system for scraper conveyor
Current scraper conveyors with permanent magnet synchronous motors often improve their efficiency by updating the mechanical structure of their drive systems, few efforts are made to optimize the control of permanent magnet synchronous motors. This paper fills the gap by involving maximum torque per ampere (MTPA) and flux-weakening controls to improve ...
