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

open access: yesThe 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 ...

Displacement analysis and numerical simulation of pile-anchor retaining structure in deep foundation pit [PDF]

open access: yes
Foundation pit excavation can cause settlement and displacement of surrounding existing buildings and roads. In order to study the influence of soil unloading on the surrounding buildings during pit foundation excavation, the application of a pile-anchor

Bite force estimates and morphological correlations of jaw muscles in parrots

open access: yesThe Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Surface settlement of deep foundation pit considering the influence of excavation and freeze-thaw

open access: yesBuildings
Abstract In seasonally frozen soil locations, to investigate ground surface deformation resulting from excavation and freeze-thaw cycles, an indoor scale model test was conducted to analyze temperature distribution and water migration in foundation pit soil.

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

open access: yesThe Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Deformation analysis of deep foundation pit in soft soil area considering space–time effect

open access: yesThe Journal of Engineering, 2019
Taking the deep foundation pit project of Taojiazhai in Shanghai as the background, combined with the real-time monitoring data, the data variation law of several monitoring items during the excavation of foundation pit are analysed.

Experimental Study on the Variation Law of Excess Pore Water Pressure at the Bottom of the Foundation Pit for Excavation

open access: yesAdvances in Materials Science and Engineering, 2020
The excavation unloading of deep foundation pits in soft soil areas often produces negative excess pore water pressure. The rebound deformation of soil on the excavation surface of the foundation pit can be predicted reliably through the accurate ...

Numerical Study on the Deformation of Tunnels by Excavation of Foundation Pit Adjacent to the Subway

open access: yes, 2022
The excavation of the foundation pit will cause changes in the soil stress field around the foundation pit, and that may have adverse effects on the adjacent subway tunnels.

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.
