Performance evaluation of the Generalized Bounding Surface Model in the simulation of Cajicá clay subjected to monotonic loading [PDF]

E3S Web of Conferences
Different constitutive models, based on principles of mechanics and experimental evidence, have been developed over several decades to represent and predict the stress-strain behavior of soils subjected to various loading conditions.

Development of experimental concepts for investigating the strength behavior of fine-grained cohesive soil in the Spacelab/space shuttle zero-g environment [PDF]

Three different sets of tests are proposed for the NASA Spacelab experimental program. The first of tests, designed to measure the true cohesion of several different soils, would be carried out in space through use of a specially prepared direct shear ...

Avalanche Dynamics in Wet Granular Materials

, 2002
We have studied the dynamics of avalanching wet granular media in a rotating drum apparatus. Quantitative measurements of the flow velocity and the granular flux during avalanches allow us to characterize novel avalanche types unique to wet media.

Influence of Load Frequency on Cohesive Soil Respond

Géosciences, 2018
The mechanism of cohesive soils response to cycling loading is less investigated compared to cohesionless soils. Multiple load-unload cycles cause significant changes in the structure of cohesive soils, which result in complex behaviour under the given ...

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Activism as education in and through the youth climate justice movement

British Educational Research Journal, EarlyView.
Abstract Young people worldwide are increasingly participating in a global movement for climate justice, yet to date, little research has examined how youth climate justice activists conceive of and experience activism as education. The present study used in‐depth, semi‐structured interviews with 16 US climate justice activists (aged 15–17) to address ...

Learning to explain environmental crises: A dialogic analysis of teacher professional learning between Chile and the United States

British Educational Research Journal, EarlyView.
Abstract Many studies and initiatives are animated by the potential for science education to intervene in the climate crisis and crises of environmental degradation and disinformation. For science teachers to learn to address these issues in their classes, their teaching must expand beyond scientific facts and face controversial social aspects. Dealing

Strategies teachers use to support students' self‐regulation skill development in mainstream primary schools: A scoping review

British Educational Research Journal, EarlyView.
Abstract This scoping review has explored the interventions and approaches used by teachers in mainstream (general education) primary schools (students aged 4–11) to support self‐regulation skill development in the classroom. The review followed the PRISMA Extension for Scoping Reviews (PRISMA‐ScR) guidelines for reporting and was guided by the Joanna ...

Marine silicon for biomedical sustainability

BMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Finite Element Analysis for Bearing Capacity of Rectangular Footing Resting Near Sloped Cohesive soil

Tikrit Journal of Engineering Sciences, 2013
Finite element method is used to investigate the ultimate bearing capacity of rectangular footing resting on cohesive soil near slope. The effect of footing aspect ratio (L/B), distance ratio (b/B), and slope angle (β) on the bearing capacity are ...
