Ground Temperature Monitoring During the Period 2004–2024 Indicates Permafrost Degradation in the Austrian Alps

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Long‐term time series on changes in the cryosphere are becoming increasingly important. This study presents data from 20 years of ground temperature monitoring from the eastern‐most confirmed permafrost site in the European Alps (Hochreichart, Austria) spanning the period 2004–2024.

Surface Behavior Regulation of Intermediates on the Copper‐Based Catalysts for Enhancing Electrocatalytic CO2 Reduction to Ethylene

open access: yesSmall, EarlyView.
This review highlights the mechanistic regulation of *CO intermediates in electrocatalytic CO2 reduction to ethylene. Strategies including surface/structural engineering, valence tuning, interface modulation, and deoxygenation pathway control are systematically mapped to *CO generation, coupling, and transformation, offering guidance for mechanism ...

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

open access: yesHigh Voltage, EarlyView.
ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐

Spinifex, fire, and fate

open access: yesGeographical Research, EarlyView.
Abstract Bushfires occur regularly in inland Australia because of the flammability of spinifex (Triodia species). Spinifex and fire are tied together by infertility: the plant is of limited palatability to consumers and accumulates into fuel. Spinifex regrows with cumulative rainfall, and fires recur every couple of decades.

A 3-year observation on analyzing cloud-to-ground lightning in Peninsular Malaysia using graph theory

open access: yesAin Shams Engineering Journal
Malaysia has a high amount of lightning events due to its geographical location and tropical climate, leading to substantial destruction of electrical systems and human injuries.

Lightning discharge identification system [PDF]

open access: yes, 1981
A system for differentiating between cloud to cloud and cloud to ground lightning discharges is described which includes an electric field antenna that senses the rate of charge of an electric field produced by a lightning discharge.

Bushfire management, prescribed burning, and a right to fire?

open access: yesGeographical Research, EarlyView.
Bushfire control is a public policy priority in an era of climate change. Prescribed burning is one management solution. Prescribed burning policies prioritise human lives and avoidance of property losses. However, some species require fire to survive. We find the ‘right to fire’ is not prioritised in prescribed burning policy.

The Issue of Pre‐Islamic Arabic Christian Poetry Revisited

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Is only very little Arabic Christian poetry extant from pre‐Islamic times? While distancing myself from Louis Cheikho's (1859–1927) view that almost all pre‐Islamic poets were Christians, I contend in this article that some of them indeed were.

Lightning current tests on radars and similar structures [PDF]

open access: yes, 2010
A lightning stroke presents a real challenge due to its potential to cause irreversible damage on electronics. Future systems are packaged in composite shielding materials, which give little or no protection with respect to the electromagnetic fields ...
