Equine Veterinary Journal, EarlyView.Abstract Background Dexmedetomidine infusions are beneficial in anaesthetised endotoxaemic horses when administered concurrent to endotoxin, but post‐conditioning effects are unknown. Objectives To evaluate whether a dexmedetomidine infusion is beneficial in horses administered Escherichia coli O55:B5 lipopolysaccharides (LPS) endotoxin prior to ...

Thorium, Probleme der Inkorporationsueberwachung - Anwendung, Messung, Interpretation
, 1993 The natural element thorium is widespread due to its technical application. The extremely low annual limits of intakes (ALI-inhalation) laid down in the Radiation Protection Ordinance, the amended version of the related guidelines, and the draft basic ...

Geological Journal, EarlyView.Energy security risk has a positive impact on material footprint. Renewable energy consumption reduces material footprint. ABSTRACT Following a high economic growth path, the group of G7 economies is found to be utilising more and more material, causing a material footprint (MF), which in turn contributes to pollution.

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool
Journal of Quaternary Science, EarlyView.ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades
Land Degradation &Development, EarlyView.ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems
Laser &Photonics Reviews, EarlyView.Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...
