Fire Histories and Rainforest Aboriginal Archaeology in the Wet Tropics Bioregion, North Queensland

Archaeology in Oceania, EarlyView.
ABSTRACT Unlike the dominant Australian savanna‐sclerophyll vegetation, tropical rainforests do not burn easily. Any evidence of fire in Australian rainforests therefore invites explanations of its source. Analysis of 187 radiocarbon dates that include selected charcoal fragments from 23 soil pits and 7 archaeological sites from the Wet Tropics ...

Research on Resonance Overvoltage of EHV Transmission Lines Caused by Lightning Strike

IEEE Access, 2021
This paper studies the mechanism and influencing factors of resonance overvoltage of EHV transmission lines caused by lightning. By analyzing the time domain steady state of the simplified resonance circuit, the physical mechanism of resonance is ...

Deciphering Neolithic Habitation in Aegean Thrace Through Geophysical Prospection Surveys

Archaeological Prospection, EarlyView.
ABSTRACT Despite the relatively extensive archaeological research conducted in Greece focusing on the Neolithic period, Aegean Thrace remains one of the least studied regions. To address this gap, the MAPFARM (Mapping the Early Farmers in Thrace) project employed systematic archaeological surface survey combined with large‐scale geophysical prospection

Cardiac Effects of Lightning Strikes

Arrhythmia & Electrophysiology Review, 2017
Lightning strikes are a common and leading cause of morbidity and mortality. Multiple organ systems can be involved, though the effects of the electrical current on the cardiovascular system are one of the main modes leading to cardiorespiratory arrest in these patients.

Balancing Barriers and Enablers: Swedish SMEs' Journey Toward Contributing to SDGs

Business Strategy and the Environment, EarlyView.
ABSTRACT Swedish multinational SMEs contribute to sustainable development goals (SDGs) by implementing various business processes and practices that are internal and external to the organization. However, research related to SDGs and business practices contributing to their implementation often focuses on large enterprises, whereas small‐ and medium ...

Research on Line Patrol Strategy of 110kV Transmission Line after Lightning Strike

MATEC Web of Conferences, 2016
Lightning faults occupy in the majority of instantaneous fault and reclosing can usually be successful, so power supply can be restored without immediate patrol in many cases. Firstly, this paper introduces the lightning fault positioning and identifying

Frequency‐Domain Subspace Identification for Noninvasive Transformer Winding Parameter Estimation and Fault Diagnostics

International Journal of Circuit Theory and Applications, EarlyView.
Noninvasive frequency‐domain method estimates transformer winding parameters from terminal measurements, eliminating the need for design data. ABSTRACT A novel frequency‐domain subspace identification method enables precise estimation of transformer winding ladder network parameters directly from terminal measurements.

Lightning Protection Methods for Wind Turbine Blades: An Alternative Approach

Applied Sciences, 2020
Lightning strikes happens in a fraction of time, where they can transfer huge amounts of charge and high currents in a single strike. The chances for a structure to be struck by lightning increases as the height increases; thus, tall structures are more ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Traditional knowledge promotes the protection of large old trees: A case from China's richest biocultural diversity area

People and Nature, EarlyView.
Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.
