Application of the Fuller–Thompson equation in sinter blend design to increase sinter productivity Open
Sintering is an important phase of the iron-making chain, as it allows the usage of finer iron ore particles in the blast furnace whilst still maintaining furnace performance. An on-going challenge for sinter plants is to obtain higher pro…

Evidence of increasing wildfire damage with decreasing property price in Southern California fires Open
Across the Western United States, human development into the wildland urban interface (WUI) is contributing to increasing wildfire damage. Given that natural disasters often cause greater harm within socio-economically vulnerable groups, r…

Rapid, non-invasive, <i>in vivo</i> measurement of tissue mechanical properties using gravitational loading and a nonlinear virtual fields method Open
Measuring the mechanical properties of soft tissues in vivo is important in biomechanics and for diagnosis and staging of diseases, but challenging because it is difficult to control the boundary conditions. We present a novel, non-invasiv…

Comprehensive review of carbon quantification by improved forest management offset protocols Open
Improved forest management (IFM) has the potential to remove and store large quantities of carbon from the atmosphere. Around the world, 293 IFM offset projects have produced 11% of offset credits by voluntary offset registries to date, ch…

Fabrication of a positional brain shift phantom through the utilization of the frozen intermediate hydrogel state Open
Synthetic models (phantoms) of the brain-skull system are useful tools for the study of surgical events that are otherwise difficult to study directly in humans. To date, very few studies can be found which replicate the full anatomical br…

<i>In vivo</i> measurement of human brain material properties under quasi-static loading Open
Computational modelling of the brain requires accurate representation of the tissues concerned. Mechanical testing has numerous challenges, in particular for low strain rates, like neurosurgery, where redistribution of fluid is biomechanic…
