Indonesian inquiry: A narrative of biocultural teaching on Sulawesi Utara

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Using phenomenology, narrative inquiry and autoethnographic approaches, this study analyses a program of faculty development conducted alongside the delivery of an international field school. Through this study, we explore the value and benefits of inter‐cultural field programming and how these might serve to complement or to redress ...

Geo-safety challenges against the site selection of engineering projects in the eastern Himalayan syntaxis area

open access: yesDizhi lixue xuebao, 2022
The eastern Himalayan syntaxis is one of the regions having the most intense tectonic activities, the most complex geological conditions, and the most frequent geohazards in the world.

Late Cenozoic tectonic stress fields of the Mongolian microplate

open access: yesComptes Rendus. Géoscience, 2012
The article deals with the Late Cenozoic fault tectonics and crustal stress state in the Mongolian block (Central and West Mongolia). An analysis was made of the stress field reconstructions, tectonic deformations in active fault zones of the central part of the block (Khangai dome), adjacent uplifts, and intermountain basins, i.e., Mongolian Altai ...

Tectonic interpretation of the connectivity of a multiscale fracture system in limestone [PDF]

open access: yes, 2016
This paper studies the statistics and tectonism of a multiscale natural fracture system in limestone. The fracture network exhibits a self‐similar characteristic with a correlation between its power law length exponent a and fractal dimension D, i.e., a ≈

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Numerical modeling of tectonic stress field and fault activity in North China

open access: yesGeodesy and Geodynamics, 2012
On the basis of a 3-dimension visco-elastic finite element model of lithosphere in North China, we numerically simulate the recent mutative figures of tectonic stress field.

Characteristics of Local Geomagnetic Field Variations and the Tectonic Stress Field Adjacent to the 21 May 2021, Ms 6.4 Yangbi Earthquake, Yunnan, China

open access: yesApplied Sciences, 2022
The tectonic processes leading up to an earthquake and the occurrence of the earthquake itself will cause local changes in the geophysical field (geomagnetic field, stress field, etc.).

Exploration of numerical simulation on paleo-tectonic stress field

open access: yesProcedia Earth and Planetary Science, 2009
AbstractThis paper analyzed the numerical simulation method of Paleo-tectonic stress field from three aspects: tectonic simulation target, establishment of the tectonic model, and tectonic modeling. Taking Chengzhuang coal mine of Jin city in Shanxi Province as an example, based on field investigations on macro and micro tectonic features, we ...

Scale-dependence of lithological control on topography: Bedrock channel geometry and catchment morphometry in western Scotland [PDF]

open access: yes, 2010
We propose that a scale-dependent topographic signature of erodibility arises due to fluvial and glacial erosion acting on different parts of the landscape at different times.

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

open access: yesDeep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...
