Behavior of Sedimentary Rock Tunnel against Rigid Projectile Impact
Applied Sciences, 2022 The tunnels in present-day cities are experiencing varying degrees of loading conditions ranging from static to extreme loading. Therefore, the stability of underground tunnels needs to be analyzed and understood for safer and strengthened design.

Archaeology in Oceania, EarlyView.ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.

Archaeology in Oceania, EarlyView.ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Archaeology in Oceania, EarlyView.ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

The Impact of Rock Morphology on Gas Dispersion in Underground Hydrogen Storage
EnergiesFluid dispersion directly influences the transport, mixing, and efficiency of hydrogen storage in depleted gas reservoirs. Pore structure parameters, such as pore size, throat geometry, and connectivity, influence the complexity of flow pathways and the ...

Archaeology in Oceania, EarlyView.ABSTRACT Both the Tasmanian devil (Sarcophilus harrisii) and the Tasmanian tiger (Thylacinus cynocephalus) are believed to have become extinct on the Australian mainland about 3000 years ago. However, until now there were only 23 known rock art depictions of the Tasmanian devil and about 150 Tasmanian tiger paintings and petroglyphs, mostly at rock art

Hydrophobization by Means of Nanotechnology on Greek Sandstones Used as Building Facades
Geosciences, 2013 Modern sustainable architecture indicates the use of local natural stones for building. Greek sandstones from Epirus (Demati, Greece, EN 12440) used as building facades meet aesthetic and have high mechanical properties, but the inevitable interaction ...
