Numerical simulation on static cone penetration test (CPT) in aeolian sand areas

Yantu gongcheng xuebao
Aeolian sand is widely distributed in western China, characterized by loose, non-cohesive soil and low water content. The static cone penetration test (CPT), as a widely used and high-quality in-situ testing technique, can easily and accurately obtain ...

Scale effects during cone penetration in spatially variable clays

, 2020
Cone penetration testing (CPT) has become one of the most commonly adopted in situ tests for site investigations, due to its reliability and repeatability of the measurements and the potential for ...

Analysation of the Effect of the Contact Properties on Soil’s Penetration Resistance in Discrete Element Simulations

Acta Technica Jaurinensis, 2019
Cone penetration in-situ tests are commonly used to measure the cone index of the soils. This measurement process can be modelled very well with Discrete Element Method (DEM) if the parameters of the correct contact model are defined properly.

An Analytical Study on Penetration and Pore Pressure Dissipation of Piezocone Test in Typical Normally and Over-Consolidated Silty Clays

Applied Sciences, 2023
The degree of the over-consolidation ratio (OCR) of silty clay affects the soil’s mechanical properties and in situ test results. The present study utilized numerical analysis to investigate the behavior of cone penetration and pore pressure dissipation ...

Experience with light dynamic penetration in a landslide locality [PDF]

, 2019
Because of vital prevention and redevelopment measures in problem localities affected by slope instability, geotechnical investigations must be carried out. One of the applicable methods is Light Dynamic Penetration (LDP).

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Cone angle influence on dynamic light cone penetrability and its effect on tip resistance prediction

Water Science
Dynamic cone penetration test has numerous advantages over commonly adopted static cone penetration test for ground characterisation. However, the major setback of the test is being unable to sorely characterise the ground.
