Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

Review and prospects of shear test of bolted rock joints

open access: yesDeep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

open access: yesFlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

New Hollow Cylinder Torsional Apparatus (HCTA) [PDF]

open access: yes
Many geotechnical problems involve the rotation of principal stress and strain directions in the ground. To assess the fundamental behaviour of soils under such conditions, a Hollow Cylinder Torsional Apparatus (HCTA) with independent controls and ...

The behaviour of concrete filled thin hollow steel column under axial load / Greg Alvin V. Thomblon [PDF]

open access: yes, 2006
A study on the behaviour of circular concrete filled hollow steel (CFS) column with various lengths under axial load has been carried out. In this experiment, the compressive strength and the buckling was measured out.

Signal-based bending stress monitoring using guided waves in hollow cylinders [PDF]

open access: yes, 2017
This work provides a time domain approach to detect stress changes in hollow cylinders using low frequency ultrasound guided waves; the proposed scheme makes uses of the subtract method for stress level estimation.

Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.
