New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

The Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Clay Content Mediates the Contribution of Suspended Sporosarcina Pasteurii to Microbial Mineralization in Sandstones

Water Resources Research
Bioaugmented microbially induced carbonate precipitation (MICP) is a potentially useful tool for permeability modification of the subsurface. There is, however, uncertainty surrounding how the transport and mineralization capability of augmenting ...

Synthesis and characterization of a highly hydrophilic nanocomposite for wettability alteration, water/oil interfacial tension reduction, and enhanced oil recovery

The Canadian Journal of Chemical Engineering, EarlyView.
Mechanism of wettability alteration, interfacial tension reduction, and oil recovery by novel nanocomposite. Abstract The development of stable nanofluids (NFs) for enhanced oil recovery (EOR) relies on optimizing interactions between reservoir rocks and fluids.
