Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Effect of silt interlayer configuration on the cyclic resistance of loose sand in direct simple shear [PDF]

E3S Web of Conferences
Liquefaction is a major source of earthquake-induced ground failure, especially in loose, saturated sandy deposits common in Indonesia. Understanding how layered soils behave under cyclic loading is therefore crucial for developing effective strategies ...

Maintaining egg freshness in the absence of refrigeration: The potential of zero‐energy cooling pots

JSFA reports, EarlyView.
Abstract Background Egg storage in regions with unreliable electricity is challenging, leading to rapid quality deterioration and postharvest losses. This study evaluated the efficacy of a Zero‐Energy Cooling (ZEC) pot, an evaporative cooling technology, for preserving table egg quality in comparison to conventional refrigeration and ambient storage ...

Modeling Biocemented Sands: Hypoplastic Model for MICP‐Based Ground Improvement

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Bio‐cementation offers a sustainable and low‐carbon alternative to conventional ground improvement methods, aligning with the growing demand for green geotechnical solutions. To enable reliable numerical simulation of bio‐cemented soil behavior in engineering applications, advanced constitutive models are required to account for the effects of

Anisotropy in the Liquefaction Resistance of Fibre Reinforced Sand

Materials, 2023
Adding discrete fibres to sand has been seen as a feasible technique to improve sand’s strength as well as liquefaction resistance. Considering the anisotropic distribution of fibre orientations, the anisotropy in the liquefaction resistance of the reinforced sand is also introduced using fibres.

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Influence of clay mineralogy on undrained cyclic strength of sand with fines

Engineering Science and Technology, an International Journal
Soils in natural or reclaimed areas frequently contain a mixture of sand, silt, and clay, rather than consisting solely of clean sand. The influence of a small proportion of fine plastic particles within a sandy matrix on liquefaction resistance still ...

An Experimental Study of Liquefaction of Saturated Sands

Soils and Foundations, 1967
Loose saturated sand was placed in a rigid box, covered with an impervious membrane, and subjected to horizontal vibration while a surcharge was applied on the membrane. The pore water pressure measured at various depths during vibration showed that the process leading to a completely liquefied state consisted of two stages : (1) a period in which the ...

Investigating the Performance of Polytetrafluoroethylene and Polyoxymethylene Creasing Rules in the Package Conversion of Coated Paperboard

Packaging Technology and Science, EarlyView.
Two sets of creasing tools were designed and machined from polytetrafluoroethylene (PTFE) and polyoxymethylene (POM) in this study to improve the creasability of commercial dispersion‐coated paperboard. Their performance was evaluated by measuring the oil and grease resistance of the samples before and after creasing/folding and comparing the results ...
