A General Model For The Ductility Of Intermetallics Applied To Fe-Co Alloys, Wesley Everhart, Joseph Newkirk

Materials Science and Engineering Faculty Research & Creative Works

The mechanical properties, specifically ductility, of high performing soft magnets such as Fe-Co alloys are a limiting factor to their broader use in a number of systems. The understanding of the mechanical robustness in these materials is currently insufficient to be able to support the growing interest in applications such as magnetic shielding or electric motors. Fe-Co alloys provide the highest commercially available magnetic saturation and high magnetic permeability but have very poor ductility. The addition of vanadium to these alloys has allowed for significant commercialization and some ductility improvements, but the fundamental reasons for the observed improvements are not …

They Never Left: Drivers Of Memory Of Dictatorship And Impressions Of Ferdinand E. Marcos As President After February 1986, Jorge V. Tigno, Geoffrey M. Ducanes, Steven Rood, Vladymir Joseph A. Licudine

Economics Department Faculty Publications

Between 1972 and 1986, Ferdinand E. Marcos of the Philippines headed an autocratic system that allowed him to rule with little to no accountability. Some 36 years after FM (as he is popularly called) and family were driven from power into exile in Hawaii, his son, Ferdinand ‘Bongbong’ Marcos, Jr., was overwhelmingly elected President in the May 2022 general elections. This turnaround seemed puzzling to many, but others saw a long-term deliberate process of rehabilitation after the family returned to the Philippines. Our paper explores how Filipinos remembered FM in the years after his ouster. What drives the memory of …

Practice Unveils Weaknesses: Analysing The Implementation Of Regulations On Seafarers’ Work/Rest Hours, Bikram S. Bhatia

World Maritime University Ph.D. Dissertations

Seafarers’ fatigue risk management is rooted in regulations on manning and work/rest hours. These regulations establish a minimum fatigue management standard achieved through work/rest hours compliance. Seafarers must maintain daily records of their work/rest hours and report any non-compliance to their company. However, adjustments to these records have been reported in the literature. Such malpractice obscures instances of non- compliance and hinders the feedback necessary for resolving these issues, including flag State review and amendments to minimum safe manning documents. It compromises the integrity of fatigue risk management and underscores the need for further research.
