Abstract The uneven ways in which climate change is taught (or not) within schools, and the uneven opportunities for students to experience justice‐oriented climate education, are curricular injustices. Recent systematic reviews of Climate Change Education literature note a depoliticising tendency in climate change education, with official curriculum ...

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Chasing Fish: 130 Years of Innovation, Displacement and Depletion in Scottish Fisheries
ABSTRACT Rebuilding the depleted fisheries of the 21st century requires an understanding of past drivers of their decline. Despite Scotland's central role in the commercial exploitation of North Sea fisheries for over a century, associations between technological innovations, regulatory introductions and fishery landings have not previously been ...

RDS-21 Face-Gear Surface Durability Tests [PDF]
Experimental fatigue tests were performed to determine the surface durability life of a face gear in mesh with a tapered spur involute pinion. Twenty-four sets of gears were tested at three load levels: 7200, 8185, and 9075 lb-in face gear torque, and ...
