The current study investigates experimentally the potential of integrating a scroll expander into a micro cogeneration steam Rankine cycle. This expander technology is not an existing technical option for such applications; consequently an existing oil-free scroll compressor is adapted to run in an expander mode with water as working fluid. The performance of the adapted scroll expander, with d...
During whole body exercise in health, maximal oxygen uptake (V̇o2max) is typically attained at or immediately before the limit of tolerance (LoT). At the V̇o2max and LoT of incremental exercise, a fundamental, but unresolved, question is whether maximal evocable power can be increased above the task requirement, i.e., whether there is a "power reserve" at the LoT. Using an instantaneous switch fr...
sciencemag.org SCIENCE scrub jays are also able to make such plans. However, these studies—especially those in the birds—have been questioned. It has been argued that planning in foraging and natural tasks is not the same as planning in a more general way. Kabadayi et al. tested ravens with tasks designed to specifically assess their general planning abilities (see the Perspective by Boeckle an...
