Care Praxis–Driven STEM Design for Sustainable and Just Communities in Middle School

Journal of Research in Science Teaching, Volume 63, Issue 7, Page 671-690, September 2026.
ABSTRACT Despite the growing interest in incorporating care ethics into STEM education, these topics are rarely integrated into K‐12 standards and pedagogical practice. We explore how care praxis, a political and ethical approach to STEM education, supports students' sense‐making in addressing real‐world problems throughout STEM design, merging social,

Ensuring electromagnetic safety at high-speed maglev transport

Transportation systems and technology, 2017
High-speed ground maglev transport creates electromagnetic interference of wide frequency spectrum during the movement. Electromagnetic interference spreads both in the surrounding environment and within the transport itself. Mathematically, electromagnetic interference is a vector (and in some cases tensor) field, where the functions are magnetic and ...
