Multi‐Species Impacts of Invasive Opuntia Cacti on Mammal Habitat Use
Ecology Letters, Volume 28, Issue 7, July 2025.Biological invasions impact ecosystems worldwide, including through changing the behaviour of native species. Here, we used camera traps to investigate the effects of invasive Opuntia spp. on the habitat use of 12 mammal species in an internationally important region of mammalian biodiversity.

Stirling Engines and Irrigation Pumping [PDF]
, 1987 This report was prepared in support of the Renewable Energy Applications and Training Project that is sponsored by the U.S. Agency for International Development for which ORNL provides technical assistance. It briefly outlines the performance that might be achievable from various kinds of Stirling-engine-driven irrigation pumps. Some emphasis is placed

Earth Surface Processes and Landforms, Volume 50, Issue 8, 30 June 2025.We found that the in‐situ 10Be concentration in multiple grain sizes can be correlated to the sediment fluxes derived from geomorphic change detection. Our results show that the magnitude of 10Be dilution relates to landslide volume, post‐seismic hillslope delivery and degree of mixing. Although the 10Be dilution factor has little to no relationship to

Solar powered Stirling cycle electrical generator [PDF]
Under NASA's Civil Space Technology Initiative (CSTI), the NASA Lewis Research Center is developing the technology needed for free-piston Stirling engines as a candidate power source for space systems in the late 1990's and into the next century.

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 11, 16 June 2025.Abstract Despite its status as a proverbial canary in the coal mine for global climate change, the Arctic has limited observational data, particularly during polar night. Longwave atmospheric emission has been recorded since 2006 at the Polar Environment Atmospheric Research Laboratory, located at Eureka, Nunavut, Canada (80° ${}^{\circ}$N).

The 1988 overview of free-piston Stirling technology for space power at the NASA Lewis Research Center [PDF]
The completion of the Space Power Demonstrator Engine (SPDE) testing is discussed, terminating with the generation of 25 kW of engine power from a dynamically-balanced opposed-piston Stirling engine at a temperature ratio of 2.0.

, 2021 Apart from this, the rhombic drive possessed several other valuable features which is listed also in the chapter 5. For example, axial movement of piston rods and absence of lateral forces, permitting good sealing of cylinder ; piston forces can now be compensated by a small buffer space and the crankcase can be at atmospheric pressure.
