The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

open access: yesThe FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.

Programming a hillslope water movement model on the MPP [PDF]

open access: yes
A physically based numerical model was developed of heat and moisture flow within a hillslope on a parallel architecture computer, as a precursor to a model of a complete catchment.

The influence of changes in water content on the electrical resistivity of a natural unsaturated loess [PDF]

open access: yes, 2012
Non-destructive methods of measuring water content in soils have been extensively developed in the last decades, especially in soil science. Among these methods, the measurements based on the electrical resistivity are simple and reliable thanks to the ...

On the capillary stress tensor in wet granular materials

open access: yes, 2011
This paper presents a micromechanical study of unsaturated granular media in the pendular regime, based upon numerical experiments using the discrete element method, compared to a microstructural elastoplastic model.

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

PENENTUAN NILAI KONDUKTIVITAS HIDROLIK TANAH TIDAK JENUH MENGGUNAKAN UJI RESISTIVITAS DI LABORATORIUM

open access: yesJurnal Teknik Pengairan, 2013
Electrical resistivity can be used to identify geotechnical parameters such as water content, liquid limit, plastic limit and unit weight. It is known that the hydraulic conductivity values can be predicted based on soil properties, so that should be ...

Fully undrained cyclic loading simulation on unsaturated soils using an elastoplastic model for unsaturated soils

open access: yesE3S Web of Conferences, 2016
Several researchers have reported that Bishop’s mean effective stress decreases in unsaturated soils under fully undrained cyclic loading conditions, and unsaturated soils are finally liquefied in a similar manner as saturated soils.
