Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device

open access: yesHigh Voltage, EarlyView.
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy

open access: yesJournal of Synchrotron Radiation, EarlyView.
For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Evidence for positive population‐level responses but not individual performance of sycamore aphids under elevated CO2

open access: yesAgricultural and Forest Entomology, EarlyView.
The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

Modern Fire Safety Protocols in the Archeological Contexts: A New Tool for Studying the Health and Behavioral Effects of Fire Use in Semi‐Closed Spaces

open access: yesArchaeometry, EarlyView.
ABSTRACT This study evaluates the application of computational fluid dynamics (CFD) simulations, integrated with controlled fire experiments, to investigate combustion processes in semi‐closed spaces. The framework enables systematic modeling of smoke dispersal, particulate transport, and hearth performance under variable morphologies and ventilation ...

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

open access: yesBoreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...
