Snake and Moon ‘Right Way Marriage’ Stories on Stone and Bark

Archaeology in Oceania, EarlyView.
ABSTRACT In northwest Australia, boab trees hold significant cultural values for First Nations people. Their leaves, bark, roots and nuts are important as traditional resources for food, medicine, fibre, water and shade and serve as reference points in the landscape. Some of the tree trunks are inscribed with images and symbols which tell of events and

Quantifying the Influence of Lightning Strike Pressure Loading on Composite Specimen Damage

Applied Composite Materials, 2019
Experimental work has shown that a component of lightning strike damage is caused by a mechanical loading. As the profile of the pressure loading is unknown a number of authors propose different pressure loads, varying in form, application area and ...

The Architecture of Large Kurgans of the Scythians and Their Periphery: A Challenge for Magnetometer Prospections in the Eurasian Steppe Belt

Archaeological Prospection, EarlyView.
ABSTRACT The burial mounds of the early Iron Age, which we will refer to below as kurgans, from the nomadic equestrian warriors of Eurasia, form a very complex group of archaeological monuments. Archaeological excavations in Aržan 2 (Siberia) and Aleksandropol (Ukraine) show that the large burial mounds are complex architectural constructions.

Review of lightning protection standard in building structures in Nigeria. [PDF]

, 2014
A lightning protection system performs a simple task. It provides a specified path on which lightning can travel. When a building structure is equiped with a lightning protection system, the distructive power of the lightning strike is directed safely ...

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.

Is Fintech Good for Bank Performance? The Case of Mobile Money in the East African Community

International Journal of Finance &Economics, EarlyView.
ABSTRACT Mobile money, a technology‐driven innovation in financial services, has profoundly penetrated the financial landscape in Sub‐Saharan Africa, including banks. Yet, besides anecdotal evidence, little is known about whether mobile money adoption enhances or worsens bank performance.

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

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 ...

Effects of boreal ground layer shrubs and bryophytes on the diversity, biomass and composition of lichen communities across contrasting ecosystems

Oikos, EarlyView.
There has been much recent interest in understanding how abiotic factors such as light, nutrients, and soil moisture affect the composition and biomass of lichen communities. Meanwhile, whether and how ground layer vegetation such as bryophytes and shrubs also influence lichen communities have received much less attention, particularly regarding how ...
