Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Instability Characteristics of and Control Techniques for Mudstone–Clay Composite Roof Roadways

Applied Sciences
In China’s northwest mining areas, shallow buried coal seams commonly feature double soft composite roof structures of mudstone and clay, resulting in poor roadway stabilization and proving challenging for effective roadway-surrounding rock (RSR) control.

Full-flow cyclic degradation and micro-structure of representative deep-sea soft clay

Yantu gongcheng xuebao, 2019
The geotechnical properties of deep-sea soft clay are quite different from those of terrestrial or offshore clay. For the representative deep-sea soft clay collected from the western region of South China Sea, an improved full-flow penetration device is ...

Structure of laponite-styrene precursor dispersions for production of advanced polymer-clay nanocomposites

, 2011
One method for production of polymer-clay nanocomposites involves dispersal of surface-modified clay in a polymerisable monomeric solvent, followed by fast in situ polymerisation.

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

Archaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

The prediction and back analysis of excavation behaviour in Oxford Clay. [PDF]

, 1996
The work described in this thesis involved the prediction and back-analysis of ground movements and pore water pressures around a temporary excavation, lOm deep, 105m long and 35m wide (50m long and lOm wide at its base) in the heavily overconsolidated

Soft clay stabilization using ladle slag-ground granulated blastfurnace slag blend

, 2019
Ladle furnace basic slag (ladle slag, LS) is a by-product of the steel refining process. There is a great amount of LS generated worldwide every year and the current solution is simply landfilling it, which causes both economic and environmental issues ...

Remote Roca: Integrating Data From Archaeological Survey, Remote Sensing and Geophysics in the Hinterland at the Long‐Lasting Mediterranean Site of Rocavecchia (Apulia, Italy)

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a multi‐method non‐invasive investigation of an approximately 4‐ha area associated with the long‐occupied coastal settlement of Rocavecchia (Apulia, southern Italy), situated between the prehistoric fortified peninsula and the Hellenistic‐Messapian walls.

Tunneling through soft clay

, 2005
A new railway line was under construction in Northern Sweden, along the shoreline of the Gulf of Bothnia, between Umea and Ornskoldsvik. The ground conditions varied dramatically: Postglacial clay and silt valleys with intermediate ridges of crystalline, Precambrian bedrock, crossing the railway line.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...
