Wave‐Velocity‐Based Temperature Monitoring Applied to Underground Power Cables in Medium‐Voltage Networks—Discrimination of Individual Cable Temperatures in a Distribution Grid

open access: yesHigh Voltage, EarlyView.
ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

Sagittal collimating diaboloid: a new grazing‐incidence mirror surface for higher‐throughput resonant inelastic X‐ray scattering spectrometers

open access: yesJournal of Synchrotron Radiation, EarlyView.
We present the analytic equations for a new grazing‐incidence mirror surface, a sagittal collimating diaboloid, and illustrate its advantages for higher‐throughput soft X‐ray spectrometer design.A major challenge in soft X‐ray spectroscopy is the efficient collection of the emitted X‐rays by grazing‐incidence mirrors.

Enter Salmon: Trophic risk mediates riverine barrier‐crossing behaviours of parr

open access: yesJournal of Animal Ecology, EarlyView.
This study provides evidence that artificial riverine barriers alter juvenile Atlantic salmon behaviour in a context‐dependent manner, with predator presence further restricting movement and barrier interactions. By addressing the overlooked impacts of barriers on river‐resident parr stages, our findings contribute to a better understanding of ...

‘CLOSING THE CARBON LOOP’: Climate Policy Discourses and the Material Politics of Municipal Waste‐to‐Biofuel Programs

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Waste‐to‐biofuel (WTB) programs have gained popularity as a municipal circular economy and an emissions reduction strategy. The upgrading of biofuels to renewable natural gas (RNG) has drawn particular interest, as RNG can displace conventional fossil fuels in any existing natural gas end use and be delivered through existing pipeline ...
