Experimental analysis of 3D cracking in drying soils using ground-penetrating radar [PDF]

open access: yes, 2017
This paper describes the capabilities of a novel technique to investigate crack formation and propagation in drying soils. The technique is a relatively simple, non-destructive indirect technique using a ground-penetrating-radar (GPR) system to detect ...

Compaction behaviour of clay [PDF]

open access: yes, 2008
This paper presents an experimental study of the compaction behaviour of non-active clay. One-dimensional static compaction tests were carried out at high and medium water content with matric suction monitoring using Trento high-capacity tensiometers. At

Experimental study on influences of wetting-drying cycles on microstructure and water-retention characteristics of clay

open access: yesYantu gongcheng xuebao
The Long-term wetting-drying cycles can weaken the engineering characteristics of subgrade fillers, resulting in engineering disasters. It is necessary to study the effects of the wetting-drying cycles on their microstructure and water-retention ...

The implementation of sinusoidal PWM on single phase 5-level cascaded H-bridge multilevel inverter [PDF]

open access: yes, 2013
In the new millennium era of technology, modern industrial devices are mostly based on electronic devices that are very sensitive to harmonics. The needs for a free-harmonics and high rating power source is extremely increased in the past few years ...

Influence of cyclic wetting‐drying on the mechanical strength characteristics of coal samples: A laboratory‐scale study

open access: yesEnergy Science & Engineering, 2019
Water‐coal interactions have gained much recent attention, although few studies focus on the strength of coal under wetting‐drying cycles. This study investigates changes in the microstructure and mechanical strength of coal that are induced by water ...

Study on Strength Attenuation Characteristics of Residual Expansive Soil under Wetting-Drying Cycles and Low Stress and Its Relationship with Shallow Landslide

open access: yesGeofluids, 2022
The rapid development of expansive soil fissures and the attenuation of strength under the action of repeated atmospheric wetting-drying cycles have a very adverse impact on the shallow stability of expansive soil slope.

Network modelling of the influence of swelling on the transport behaviour of bentonite [PDF]

open access: yes, 2016
Wetting of bentonite is a complex hydro-mechanical process that involves swelling and, if confined, significant structural changes in its void structure.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Experimental Investigation of the Physical Properties and Microstructure of Slate under Wetting and Drying Cycles Using Micro-CT and Ultrasonic Wave Velocity Tests

open access: yesSensors, 2020
Cyclic wetting and drying processes have been considered as important factors that accelerate the weathering process and have deteriorative effects on rock properties.
