Dry–wet cycles increase pesticide residue release from soil [PDF]

open access: yesEnvironmental Toxicology and Chemistry, 2012
AbstractSoil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9–17 years) 14C-labeled residues of the herbicides ethidimuron (ETD)

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.

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

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 ...

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 ...

Nonequilibrium Wet–Dry Cycling Acts as a Catalyst for Chemical Reactions

open access: yesThe Journal of Physical Chemistry B
Recent experimental studies suggest that wet-dry cycles and coexisting phases can each strongly alter chemical processes. The mechanisms of why and to which degree chemical processes are altered when subject to evaporation and condensation are unclear. To close this gap, we developed a theoretical framework for non-dilute chemical reactions subject to ...

Uranium storage mechanisms in wet-dry redox cycled sediments

open access: yesWater Research, 2019
Biogeochemical redox processes that govern radionuclide mobility in sediments are highly sensitive to forcing by the water cycle. For example, episodic draining and intrusion of oxidants into reduced zones during dry seasons can create biogeochemical seasonal hotspots of enhanced and changed microbial activity, affect the redox status of minerals ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Impact of wetting/drying cycles on the hydromechanical behaviour of a treated soil [PDF]

open access: yesE3S Web of Conferences, 2020
The positive effects of lime or cement treatment could be altered by weathering in the very long term. In this context, the main purpose of this study is to examine the impact of wetting/drying cycles on the strength and the hydraulic conductivity of a ...

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.
