Truth‐telling in the Australian Curriculum

open access: yesThe Curriculum Journal, EarlyView.
Abstract Unlike Canada and South Africa, Australia has not completed a national Truth‐telling of First Nations histories. As a consequence, the curriculum is at risk of excluding Truth‐telling, leading to indoctrination of past injustices as part of school learning.

Computation of Electric Field on High Voltage Polymeric Insulators Using Actual Model With Optimal Corona Ring Dimensions

open access: yesEnergy Science &Engineering, EarlyView.
Combination of four cases (few water drops, more water drops, different sizes of water drops (16.8 μL and 56.5 μL), and clean insulator) with the use of corona ring (140‐40‐90). ABSTRACT This article deals with the calculations of the electric field and the potential distribution of the polymer insulators of the HVTLs with the use of corona rings.

Observation of an upward lightning flash with 21 upward positive leaders initiated from different wind turbines in wind farm

open access: yesHigh Voltage
As the wind turbine height increases, the probability of multiple upward leaders flashes within the wind farm increases. In this study, an upward lightning flash containing 21 upward positive leaders (UPLs) initiated from different wind turbines in ...

The western North American forestland carbon sink: will our climate commitments go up in smoke?

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Pathways to achieving net‐zero and net‐negative greenhouse‐gas (GHG) emission targets rely on land‐based contributions to carbon (C) sequestration. However, projections of future contributions neglect to consider ecosystems, climate change, legacy impacts of continental‐scale fire exclusion, forest accretion and densification, and a century or more of ...
